Disclosure of Invention

Problems to be solved by the invention

The garment disclosed in patent document 1 (japanese patent No. 6762991) is produced by sewing a plurality of members such as a front side panel, two rear side panels, a collar, a sleeve portion, and a cuff into a curved shape. Accordingly, the clothing disclosed in patent document 1 (japanese patent No. 6762991) is complicated in the process of manufacturing, and is not suitable for mass production.

The invention provides a method for manufacturing clothes, which is simple in manufacturing method and can be manufactured efficiently.

Means for solving the problems

The manufacturing method of the garment of the invention comprises the following steps: a first conveying process, a second conveying process, a first forming process, a first overlapping process, a second forming process, and a separating process. In the first conveying step, a first sheet for forming a first member that is one of the front body and the rear body is conveyed. In the second conveying step, a second sheet for forming a second member that is the other of the front body and the rear body is conveyed. In the first forming step, the third sheet to be conveyed and the fourth sheet to be conveyed are overlapped, and the third sheet to be conveyed and the fourth sheet to be conveyed in an overlapped state are partially joined and cut at a predetermined position, thereby forming a tubular sleeve member. In the first overlapping step, the conveyed first sheet is overlapped with the sleeve member. In the second overlapping step, the conveyed first sheet and the conveyed second sheet are overlapped so that the sleeve member overlapped with the first sheet is arranged between the first sheet and the second sheet. In the second forming step, the first sheet and the second sheet conveyed in the overlapped state are partially joined in accordance with the outer edge shape of the garment. In the second forming step, the first sheet and the second sheet conveyed in the overlapped state are partially cut according to the outer edge shape of the garment. In the separation step, the garment formed in the second forming step is separated from the first sheet and the second sheet.

ADVANTAGEOUS EFFECTS OF INVENTION

In the method for manufacturing clothes of the present invention, clothes can be manufactured by relatively simple steps, and clothes can be manufactured efficiently.

In the method for producing a garment according to the present invention, the sleeve member is disposed between the first sheet for forming the first member and the second sheet for forming the second member, and therefore, the portion of the outer surface (front surface) of the front body and the sleeve member can be covered with the rear body. Therefore, in the method for producing clothing according to the present invention, clothing excellent in hygiene can be produced in which contamination of the outer surface of the front body or the sleeve member of the produced clothing due to contact with a human hand or the like can be suppressed.

(1) Clothes with a pair of elastic members

(1-1) Summary

A garment 1 manufactured by the garment manufacturing method of the present invention will be described with reference to fig. 1 to 3. Fig. 1 is a schematic view of a state when the garment 1 is worn by a wearer, from the front side. Fig. 2 is a schematic view of the state when the garment 1 is worn by the wearer, from the rear side. Fig. 3 is a schematic view of the state of the garment 1 before wearing, as viewed from the side facing the outside (the side not facing the person) when worn by the wearer. In fig. 3, from the viewpoint of easy view, the members other than the left rear member 20L and the sleeve member 30 that cannot be directly seen are omitted from illustration.

In fig. 1 and 2, a state is depicted in which a belt to be described later for bringing the garment 1 into close contact with the body is not connected. In fig. 3, the garment 1 is depicted in a state of being unfolded for wearing the garment 1, and the garment 1 is folded by the garment manufacturing system 100 for the purpose of compacting the garment 1, not the garment at the time point when the garment manufacturing system 100 described later completes the manufacturing of the garment 1.

In the following description of the garment 1 or the members constituting the garment 1, terms such as "upper", "lower", "front (front)", "rear (back)", "right" and "left" are sometimes used to indicate directions or orientations. These expressions refer to "upper", "lower", "front", "rear", "right", "left" in the wearing state of the garment 1 unless otherwise specified. Specifically, the upper side of the garment 1 refers to the head side of the wearer in a state where the garment 1 is worn normally, the front side of the garment 1 refers to the chest (front) side of the wearer in a state where the garment 1 is worn normally, and the right side of the garment 1 refers to the right arm side of the wearer in a state where the garment 1 is worn normally. The same applies to other expressions.

In the following description of the garment 1 or the members constituting the garment 1, terms such as "outer surface" and "inner surface" are sometimes used, but unless otherwise noted, these expressions refer to "outer surface" and "inner surface" and the like in the worn state of the garment 1. Specifically, the inner surface refers to the surface on the side facing the wearer in the state where the garment 1 is worn normally, and the outer surface refers to the surface on the side not facing the wearer in the state where the garment 1 is worn normally.

The use of the garment 1 manufactured by the manufacturing method of the present invention is not limited, and the garment may be used as, for example, an operating gown or a protective cover for use in an operation. Although the number of uses is not limited, the garment 1 is, for example, a disposable garment that is discarded after use. The garment 1 covers the wearer's upper body and also from the waist portion of the wearer's lower body to the vicinity of the ankle.

The main components of the garment 1 include: a front member 10 (front body) as an example of the first member, a rear member 20 (rear body) as an example of the second member, a first sleeve member 30R (right sleeve) and a second sleeve member 30L (left sleeve). The difference between the first sleeve member 30R and the second sleeve member 30L is that the shape and structure are the same with respect to the difference on which side the members 10, 20 are arranged (which arm of the wearer is inserted). Hereinafter, when it is not necessary to particularly distinguish between the first sleeve member 30R and the second sleeve member 30L, the first sleeve member 30R and the second sleeve member 30L may not be separated, but the sleeve member 30 may be referred to by a single name.

The front member 10, the rear member 20, and the sleeve member 30 constitute the garment 1 by joining the front member 10 and the sleeve member 30 at a predetermined location, joining the rear member 20 and the sleeve member 30 at a predetermined location, and joining the front member 10 and the rear member 20 at a predetermined location. The joining of the front member 10 and the sleeve member 30, the joining of the rear member 20 and the sleeve member 30, and the joining of the front member 10 and the rear member 20 will be described later.

The material of the front member 10 and the rear member 20 is not limited, and is, for example, a film or a nonwoven fabric made of a thermoplastic resin. For example, the front and rear members 10 and 20 are made of a polyolefin resin such as polyethylene or polypropylene, polyethylene terephthalate, nylon, or the like. By using these materials, the front member 10 and the rear member 20 can be heat-fused. The front member 10 and the rear member 20 need not be made of a single type of material, but may be made of a material made of a plurality of materials by stacking a plurality of materials.

For the purpose of reinforcing and improving the comfort of the wearer, other members may be locally attached to the front member 10 and the rear member 20. Although not limited thereto, in the present embodiment, a reinforcing member 12 (see fig. 1) having a material different from that of the front side member 10 is attached to the inner surface of the front side member 10. The reinforcing member 12 is disposed in a region from the vicinity of the chest of the front member 10 to the side of the skirt 18 in the substantially entire lateral direction of the front member 10. As shown in fig. 1, a neck collar member 15a (nonwoven fabric) is attached to the inner surface of the front member 10 around the collar 14 on the front side of the garment 1. In the present embodiment, as shown in fig. 1, a neck collar member 25a (nonwoven fabric) is attached to the inner surface of the rear member 20 around the collar 24 on the rear side of the garment 1.

The front member 10, the rear member 20, and the sleeve member 30 will be described in more detail.

(1-2) Details of the respective Components

(1-2-1) Front side Member

As shown in fig. 1, the front member 10 is a substantially rectangular sheet-like member. However, a collar 14 having a substantially C-shape is formed in an upper portion of the front side member 10 so as to be recessed downward so as to pass through the head of the wearer. The shape of the neckline 14 is arbitrary, and for example, the neckline 14 may have a substantially V-shape. Further, as shown in fig. 1, the shoulder portion 16 of the front side member 10 covering the shoulder of the wearer includes an inclined portion 16a extending obliquely downward from the collar 14 side toward the sleeve member 30 side to match the body of the wearer. Further, as shown in fig. 1, the shoulder portion 16 of the front side member 10 includes a horizontal portion 16b extending between the collar 14 and the inclined portion 16 a. Since the shoulder portion 16 has such a structure, the end 16c of the shoulder portion 16 on the side of the sleeve member 30 is closer to the hem (the hem 18 of the front side member 10) of the garment 1 than the end 16d of the shoulder portion 16 on the side of the neckline 14.

A first front belt 11a and a second front belt 11b are attached as accessories near the waist of the outer surface of the front side member 10. In fig. 1, the first front belt 11a and the second front belt 11b are depicted in front of the front side member 10, but the first front belt 11a and the second front belt 11b are tied up on the back side of the wearer when the wearer actually wears the garment 1. By bundling the first front belt 11a and the second front belt 11b on the back side of the wearer, the garment 1 can be brought into close contact with the wearer's body in the vicinity of the waist of the wearer.

(1-2-2) Rear side Member

The rear side member 20 includes a right rear side member 20R and a left rear side member 20L. The right rear member 20R and the left rear member 20L are substantially rectangular sheet-like members, respectively. In the garment 1, the right rear side member 20R and the left rear side member 20L are arranged in a manner overlapping each other. Specifically, in the garment 1, the left end vicinity portion of the right rear side member 20R is arranged to overlap with the right end vicinity portion of the left rear side member 20L. In fig. 2, the left end vicinity portion of the right rear member 20R is disposed rearward of the right end vicinity portion of the left rear member 20L, but the shape of the garment 1 is not limited to this shape, and the design deformation may be performed so that the right end vicinity portion of the left rear member 20L is disposed rearward of the left end vicinity portion of the right rear member 20R.

Hereinafter, the shape of each of the right rear member 20R and the left rear member 20L will be described by considering the right rear member 20R and the left rear member 20L as an integral rear member 20, instead of describing the shape thereof.

The outer shape of the rear side member 20 has the same outer shape as the front side member 10. As shown in fig. 2, the rear member 20 is a substantially rectangular sheet-like member. However, a collar 24 having a substantially C-shape is formed in an upper portion of the rear member 20 so as to be recessed downward so as to pass through the head of the wearer. The shape of the collar 24 is arbitrary, and for example, the collar 24 may have a substantially V-shape. Further, as shown in fig. 2, the shoulder portion 26 of the rear side member 20 covering the shoulder of the wearer includes an inclined portion 26a extending obliquely downward from the collar 24 side toward the sleeve member 30 side to match the body of the wearer. Further, as shown in fig. 2, the shoulder portion 26 of the rear side member 20 includes a horizontal portion 26b extending between the collar 24 and the inclined portion 26 a. Since the shoulder portion 26 has such a structure, an end 26c of the shoulder portion 26 on the side of the sleeve member 30 is closer to the hem (hem 28 of the rear side member 20) of the garment 1 than an end 26d of the shoulder portion 26 on the side of the collar 24.

The front side member 10 and the rear side member 20 are joined and integrated at the following portions. The shoulder portion 26 of the rear side member 20 engages the shoulder portion 16 of the front side member 10. The left and right outer edges of the rear member 20 and the front member 10 are joined to the entire lower hem 18, 28 of the front member 10 and the rear member 20 from the joint (underarm portion) joined to the lower end portions of the sleeve members 30 of the front member 10 and the rear member 20.

In addition, the neckline 24 of the rear side member 20 and the neckline 14 of the front side member 10 are not joined because the wearer needs to extend the head. In addition, the skirt 28 of the rear side member 20 and the skirt 18 of the front side member 10 are not engaged in order for the wearer to extend the foot.

A first neck strap 22a and a second neck strap 22b are attached as accessories to the outer surface of the rear member 20 near the collar 24. The first neck strap 22a is mounted on the left rear side member 20L, and the second neck strap 22b is mounted on the right rear side member 20R. When the wearer wears the garment 1, the first neck strap 22a and the second neck strap 22b are strapped on the back side of the wearer. By strapping the first neck strap 22a and the second neck strap 22b on the back side of the wearer, the garment 1 can be brought into close contact with the wearer's body around the wearer's neck.

Further, a waist outer belt 21a and a waist inner belt 21b are attached as accessories in the vicinity of the waist of the rear side member 20. The waist outer belt 21a is attached to the outer surface of the left rear side member 20L. The waist inner belt 21b is attached to the inner surface of the right rear side member 20R. When the wearer actually wears the garment 1, the waist outer belt 21a and the waist inner belt 21b are bound on the back side of the wearer. By bundling the waist outer belt 21a and the waist inner belt 21b on the back side of the wearer, the right rear side member 20R and the left rear side member 20L can be suppressed from being separated.

Further, a surface fastener 22c (hook portion) is provided as an accessory on the inner surface of the right rear side member 20R opposite to the outer surface of the left rear side member 20L. When the wearer actually wears the garment 1, the surface fastener 22c is attached to the fibers (loop fastener portion) of the outer surface of the left rear side member 20L, and is used to attach the garment 1 to the wearer's body around the neck of the wearer.

(1-2-3) Sleeve Member

The sleeve member 30 is the portion of the wearer of the garment 1 that passes through the arm.

The sleeve member 30 is a cylindrical member. A cuff 32 for extending the hand of the wearer of the garment 1 is provided on one end side of the sleeve member 30. An arm hole 34 into which the wearer of the garment 1 inserts his or her arm is provided at the other end side of the sleeve member 30.

The sleeve member 30 is joined to the front member 10 and the end of the rear member 20 on the arm hole 34 side. Specifically, the end outer edge of the front surface of the first sleeve member 30R on the arm hole 34 side is joined to the right outer edge of the outer surface of the front side member 10 over the entire area in the up-down direction. Further, the end outer edge of the rear surface of the first sleeve member 30R on the arm hole 34 side is joined to the right outer edge of the outer surface of the rear side member 20 (right rear side member 20R) over the entire area in the up-down direction. Further, the end outer edge of the front surface of the second sleeve member 30L on the arm hole 34 side is joined to the left outer edge of the outer surface of the front side member 10 over the entire area in the up-down direction. Further, the end outer edge of the rear surface of the second sleeve member 30L on the arm hole 34 side is joined to the left outer edge of the outer surface of the rear side member 20 (left rear side member 20L) over the entire area in the up-down direction.

In the sleeve member 30 of the present embodiment, the opening size of the cuff 32 is formed smaller than the opening size of the arm hole 34 of the sleeve member 30. By forming the cuffs 32 of the sleeve members 30 small (by making the opening sizes of the cuffs 32 small), the cuffs 32 of the excess sleeve members 30 are less likely to interfere with the work. On the other hand, by making the opening size of the arm hole 34 of the sleeve member 30 large, the wearer of the garment 1 can easily freely move his or her arms.

Further, a stretchable material E is disposed (attached) to the cuff 32 of the sleeve member 30. The expansion and contraction member E is, for example, a sheet-like member or a wire rubber having high elasticity. Since the extension and contraction piece E of the cuff 32 of the sleeve member 30 tightens the cuff 32, the cuff 32 does not easily interfere with the work, and foreign matter does not easily enter the inside of the garment 1 from the cuff 32.

(1-3) Method of wearing clothing

The wearing method of the garment 1 will be described.

First, before describing the wearing method of the garment 1, the shape of the garment 1 before wearing by the wearer will be described. In order to achieve the compactness of the manufactured garment 1, the garment manufacturing system 100 for manufacturing the garment 1 manufactures the garment 1 in a folded state, as will be described later. However, the shape of the garment 1 after the folded garment 1 manufactured by the garment manufacturing system 100 is not limited to the folded garment 1, but the shape of the garment 1 before the wearer wears the garment 1.

After the garment 1 is worn, the outer surface of the front side member 10 is disposed in front of the wearer and the outer surface of the rear side member 20 is disposed in rear of the wearer. Further, after the garment 1 is worn, the inner surface of the front side member 10 is opposed to the front surface of the wearer, and the inner surface of the rear side member 20 is opposed to the back surface of the wearer.

In contrast, in the garment 1 before the wearer, the inner surface of the front side member 10 (the surface facing the wearer after the wearer) is disposed on the outside, and the inner surface of the rear side member 20 (the surface facing the wearer after the wearer) is disposed on the outside. In other words, in the garment 1 before wearing by the wearer, the outer surface of the front side member 10 (the surface that does not face the wearer after wearing) is disposed inside, and the outer surface of the rear side member 20 (the surface that does not face the wearer after wearing) is disposed inside. In other words, in the garment 1 before the wearer wears, the surface disposed on the outer side is not exposed to the outside when the wearer wears the garment. In the garment 1 before being worn by the wearer, the sleeve member 30 is disposed between the outer surface of the front member 10 and the outer surface of the rear member 20. The arm holes 34 of the sleeve member 30 disposed between the front member 10 and the rear member 20 are opened on the side surface of the garment 1. In other words, before the garment 1 is worn by the wearer, the wearer is in a state in which the arm is insertable into the arm hole 34 of the sleeve member 30.

When the wearer wears the garment 1, the wearer faces the inner surface (the surface facing the wearer after wearing) of the front side member 10 of the garment 1 in the shape of fig. 3 to the front surface of the wearer. Then, the wearer inserts the right arm from the arm hole 34 of the first sleeve member 30R, and protrudes the right wrist from the cuff 32 of the first sleeve member 30R. Further, the wearer inserts the left arm from the arm hole 34 of the second sleeve member 30L, and extends the left wrist from the cuff 32 of the second sleeve member 30L.

In this state, for example, the auxiliary person wearing the clothing 1 covers the back surface of the wearer with the right rear side member 20R and the left rear side member 20L so that the inner surface of the rear side member 20 (the inner surface of the right rear side member 20R and the inner surface of the left rear side member 20L) arranged in front of the wearer faces the back surface of the wearer. Then, the assistant attaches the face fastener 22c provided on the inner surface of the right rear side member 20R to the fiber (loop fastener) of the outer surface of the left rear side member 20L. The assistant wears the first neck strap 22a and the second neck strap 22b on the back side of the wearer, and wears the waist outer strap 21a and the waist inner strap 21b on the back side of the wearer. Next, the auxiliary person or the wearer ties the first front tape 11a and the second front tape 11b on the back side of the wearer. In the above manner, the wearer can wear the garment 1.

(2-1) Material for manufacturing the front side Member and the rear side Member

In the manufacture of the garment 1, as main materials, a first sheet W1 for manufacturing the front side member 10, a second sheet W2 for manufacturing the rear side member 20, and a third sheet W3 and a fourth sheet W4 for manufacturing the sleeve member 30 are used. The materials used for the first sheet W1, the second sheet W2, the third sheet W3, and the fourth sheet W4 are described in the description of the method for producing the garment 1.

The first sheet W1 and the second sheet W2 are sheets of thermoplastic resin, for example. The width of the first sheet W1 (the length in the direction perpendicular to the conveying direction of the first sheet W1, see fig. 4) is equal to the length L1 (see fig. 1) of the left-right width of the front member 10 and the rear member 20 of the garment 1.

The third sheet W3 and the fourth sheet W4 are sheets formed by stacking, for example, nonwoven fabrics and reinforcements. The width of the third sheet W3 and the fourth sheet W4 (the length in the direction orthogonal to the conveyance direction, see fig. 6) is equal to the length L2 (see fig. 2) of the left-right width of the sleeve member 30.

The functions of each device will be described together with the manufacturing method.

The flow of the manufacturing method described below is merely an example. For example, the order of execution of the steps may be changed within a range where there is no contradiction. For example, if there is no contradiction, two or more steps may be performed simultaneously.

In the following description, the expression "a" is sometimes used to overlap "B", but the expression is not limited to the positional relationship in which "B" is arranged above "a", but means that "a" and "B" are in an overlapping state. That is, if there is no contradiction, the expression "a" overlaps "B" also includes a mode in which "a" is arranged above "B", and a mode in which "a" and "B" are arranged in the horizontal direction (adjacent in the horizontal direction).

The first sheet conveying apparatus 110 (see fig. 13) conveys a first sheet W1 fed from a raw material roll (not shown) using, for example, a plurality of rollers (step A1 in fig. 10). The step A1 in fig. 10 is an example of a first conveyance step of conveying a first sheet W1 for forming a front member 10 that is one of a front body and a rear body (herein, a front body). Although the detailed description is omitted here, the first sheet W1 may be a sheet formed by stacking a plurality of sheets, and the step of manufacturing the garment 1 may include a step of manufacturing the first sheet W1 formed by stacking a plurality of sheets.

The reinforcing member joining device 120 (see fig. 13) joins the reinforcing member 12 to the first sheet W1 (step A2 in fig. 10) conveyed by the first sheet conveying device 110, wherein the reinforcing member 12 is cut out of a sheet (not shown) fed out from a raw material roll (not shown). The joining method may be welding or bonding, and may be appropriately selected. The reinforcing member joining device 120 (see fig. 13) joins the reinforcing member 12 to the conveyed first sheet W1 so that the reinforcing member 12 is disposed at a predetermined position on the inner surface of the front side member 10 in the manufactured garment 1. The shape of the reinforcing member 12 may be appropriately determined, and is, for example, rectangular.

The sheet joining device 130 (see fig. 13) joins the neck sheet 15 to the first sheet W1 (step A3 in fig. 10) conveyed by the first sheet conveying device 110, wherein the neck sheet 15 is cut out of a sheet (not shown) fed from a roll (not shown) of raw material. The joining method may be welding or bonding using an adhesive, and may be appropriately selected. The sheet joining device 130 joins the neck panel 15 to the conveyed first sheet W1 so that the neck panel 15a (the member left in the front member 10 after the neck panel 15 is cut together with the first sheet W1 in the subsequent step) is disposed at a predetermined position around the neckline 14 on the inner surface of the front member 10 in the produced garment 1. The shape of the neck surrounding sheet material 15 may be appropriately determined, for example, rectangular.

The front tape joining device 140 (see fig. 13) joins the first front tape 11a to the first sheet W1 (step A4 in fig. 10) conveyed by the first sheet conveying device 110, wherein the first front tape 11a is formed as follows: the sheet Wa1 and the sheet Wa2 cut from a roll of raw material (not shown) are overlapped, and the overlapped sheet is folded one or more times in a direction orthogonal to the conveying direction, joined at a predetermined position, and cut at a predetermined width in the conveying direction. The front tape joining device 140 joins the first front tape 11a to the conveyed first sheet W1 so that the first front tape 11a is disposed at a predetermined position of the front side member 10 in the manufactured garment 1. The joining method may be welding or bonding, and may be appropriately selected.

The front tape joining device 150 (see fig. 13) joins the second front tape 11b formed of the sheets Wb1 and Wb2 to the first sheet W1 conveyed by the first sheet conveying device 110 in the same manner as the front tape joining device 140 (step A5 in fig. 10). The front tape joining device 150 joins the second front tape 11b to the conveyed first sheet W1 so that the second front tape 11b is disposed at a predetermined position of the front side member 10 in the manufactured garment 1. The joining method may be welding or bonding, and may be appropriately selected.

The adhesive applying device 160 (see fig. 13) applies an adhesive to the outer surface of the first sheet W1 (the surface that becomes the outer surface of the front member 10 when the garment 1 is formed) conveyed by the first sheet conveying device 110 at a position where the adhesive is joined to the sleeve member 30 (the first sleeve member 30R and the second sleeve member 30L) (step A6 in fig. 10). Specifically, the adhesive applying device 160 applies an adhesive to a position of the right edge portion of the outer surface of the first sheet W1, which is in contact with the first sleeve member 30R placed on the first sheet W1 in a subsequent process. The adhesive applying device 160 applies an adhesive to a position of the left edge portion of the outer surface of the first sheet W1, which is in contact with the second sleeve member 30L placed on the first sheet W1 in a subsequent step. Although not limited thereto, the adhesive applied by the adhesive applying device 160 is a hot melt adhesive.

Here, the process of forming the sleeve member 30 will be described with reference to fig. 6, 11, and 13, in which the process of the first sheet W1 is temporarily stopped.

The sleeve member 30 is mainly composed of a third sheet W3 and a fourth sheet W4.

The third sheet forming and conveying apparatus 210 (see fig. 13) conveys (step B1 in fig. 11) a third sheet W3, wherein the third sheet W3 is manufactured by superposing (see fig. 6) a sleeve sheet W3nw of nonwoven fabric fed from a raw material roll (not shown) and a reinforcing sheet W3r of a reinforcing material fed from the raw material roll (not shown) and joining them. In fig. 13, a mechanism for joining the sleeve sheet W3nw and the reinforcing sheet W3r together is not shown.

The expansion and contraction member joining device 205 joins the third sheet W3 to be conveyed by disposing expansion and contraction members E at both end portions in a direction orthogonal to the direction in which the third sheet W3 is conveyed (step B2 in fig. 11). The process of step B2 in fig. 11 is an example of the arrangement process.

The fourth sheet forming and conveying apparatus 220 (see fig. 13) conveys (step B3 in fig. 11) a fourth sheet W4, in which the fourth sheet W4 is manufactured by superposing (see fig. 6) a sleeve sheet W4nw of nonwoven fabric fed from a raw material roll (not shown) and a reinforcing sheet W4r of a reinforcing material fed from the raw material roll (not shown). In fig. 13, a mechanism for joining the sleeve sheet W4nw and the reinforcing sheet W4r together is not shown.

For convenience of illustration, step B3 is described after step B1 and step B2, but this does not mean that step B3 is performed after step B1 and step B2. Steps B1 and B2, and steps B3 and B4 described later may be performed in parallel.

The expansion and contraction member joining device 215 joins the fourth sheet W4 to be conveyed by disposing expansion and contraction members E at both end portions in a direction orthogonal to the direction in which the fourth sheet W4 is conveyed (step B4 in fig. 11). The process of step B4 in fig. 11 is an example of the arrangement process.

The third sheet W3 after the attachment of the extensible member E and the fourth sheet W4 after the attachment of the extensible member E are joined (step B5 of fig. 11) to be in an overlapped state. The third sheet W3 and the fourth sheet W4 in the overlapped state are conveyed in the first direction D1 (see fig. 13).

The sleeve edge joining device 230 (see fig. 13) partially joins the third sheet W3 and the fourth sheet W4 conveyed in the first direction D1 (see fig. 6) in an overlapped state (step B6 of fig. 11). Specifically, the sleeve edge joining device 230 joins the third sheet W3 and the fourth sheet W4 conveyed in the first direction D1 in an overlapped state to each other along the entire width direction of the third sheet W3 and the fourth sheet W4 in the direction intersecting the first direction D1 (see a thick solid line drawn above the reference symbol B6 in fig. 6). More specifically, the sleeve edge joining device 230 joins the third sheet W3 and the fourth sheet W4 conveyed in the first direction D1 in an overlapped state so that the shape of the upper edge and the lower edge of the outer shape of the sleeve member 30 substantially matches with the shape of one joining portion and the joining portion adjacent to the joining portion in the first direction D1 when viewed from the direction perpendicular to the sheet surfaces of the third sheet W3 and the fourth sheet W4, and the third sheet W3 and the fourth sheet W4 are joined in their entirety in the width direction. The third sheet W3 and the fourth sheet W4 are joined by the sleeve edge joining device 230 in this manner, and when the third sheet W3 and the fourth sheet W4 are conveyed in the first direction D1 in an overlapped state as viewed from a direction perpendicular to the sheet surfaces of the third sheet W3 and the fourth sheet W4, the sleeve members 30 of the cuffs 32 are disposed on one end side in the second direction D2 orthogonal to the first direction D1 and the sleeve members 30 of the cuffs 32 are disposed on the other end side in the second direction D2 are alternately disposed (in which the sleeve members 30 are connected to each other) (see fig. 6).

The joining method of the third sheet W3 and the fourth sheet W4 by the sleeve edge joining device 230 may be heat welding or ultrasonic welding. The joining method of the third sheet W3 and the fourth sheet W4 by the sleeve edge joining device 230 may be bonding using an adhesive.

The sleeve edge cutting device 240 (see fig. 13) is disposed downstream of the sleeve edge joining device 230 in the first direction D, and cuts the joining portion of each of the third sheet W3 and the fourth sheet W4 conveyed in the overlapped state in the first direction D1, joined by the sleeve edge joining device 230, at the central portion of the joining portion in the extending direction of the joining portion (step B7). In other words, the sleeve edge cutting device 240 cuts the sleeve members 30 in the connected state on the third sheet W3 and the fourth sheet W4 that are conveyed, and forms sleeve members 30 independent of the other sleeve members 30.

In the above embodiment, by performing the overlapping, joining, and cutting of the third sheet W3 and the fourth sheet W4 (by performing steps B5 to B7, which are an example of the first forming step), in the clothing manufacturing system 100, the tubular first sleeve member 30R in which the cuffs 32 are disposed on one end side in the second direction D2 orthogonal to the first direction D1 and the tubular second sleeve member 30L in which the cuffs 32 are disposed on the other end side in the second direction D2 are alternately formed from the third sheet W3 and the fourth sheet W4 that are conveyed in the first direction D1 in the overlapped state. In the present embodiment, the first sleeve member 30R serves as a right sleeve, and the second sleeve member 30L serves as a left sleeve. In this way, by alternately forming the first sleeve member 30R and the second sleeve member 30L from the third sheet W3 and the fourth sheet W4 that are conveyed in the first direction D1 in the overlapped state, the occurrence of the scraps can be suppressed even in the case where the sleeve member 30 having the smaller opening on the cuff 32 side than the opening on the arm hole 34 side is formed (even in the case where the sleeve member 30 having the different thickness is formed).

In the sleeve member 30, the extension and contraction member E of the cuff 32 is useful because the cuff 32 can be tightened. However, the telescoping member E on the arm hole 34 side is not particularly required, and preferably is not present. For this reason, for example, in the method of manufacturing the garment 1, it is preferable to provide a cutting step of cutting the expansion element E attached to the portion to be the arm hole 34 of the sleeve member 30 at the same time or before or after the steps of the steps B6 and B7. In the cutting step, for example, the portion of the arm hole 34 serving as the sleeve member 30 is heated, and the expansion and contraction member E is cut by heat.

The sleeve member 30 formed by performing the steps B5 to B7 as an example of the first forming step is carried by the position adjusting devices 245 and 250 to the sleeve member superimposing devices 260 and 270 (step B8), and the sleeve member superimposing devices 260 and 270 superimpose the sleeve member 30 on the first sheet W1. The position adjustment devices 245 and 250 transport the first sleeve member 30R to the sleeve member superimposing device 260 and transport the second sleeve member 30L to the sleeve member superimposing device 270. Specific description will be given.

The position adjustment device 245 conveys the sleeve member 30 to the position adjustment device 250, and delivers the sleeve member 30 to the position adjustment device 250. The position adjustment device 245 has a function of adjusting the distance between the adjacent sleeve members 30 in the conveying direction of the sleeve members 30. For example, the position adjustment device 245 includes a roller and a plurality of holding members (not shown) provided on the outer circumference of the roller in the circumferential direction. The holding member is a member that receives and holds the formed sleeve member 30. When the roller is rotated and the holding member is rotated to convey the sleeve member 30, the position adjustment device 245 changes the relative position of the holding member with respect to the roller in the circumferential direction of the roller, thereby expanding the distance between the sleeve members 30 adjacent in the conveying direction of the sleeve member 30.

The position adjustment device 250 conveys the first sleeve member 30R of the sleeve members 30 received from the position adjustment device 245 to the sleeve member superimposing device 260, and conveys the second sleeve member 30L to the sleeve member superimposing device 270. The position adjustment device 250 has at least a function of adjusting the distance between the sleeve members 30 adjacent to each other in the direction (width direction) orthogonal to the conveying direction. For example, the position adjustment device 250 includes a roller and a plurality of holding members (not shown) provided on the outer circumference of the roller in the circumferential direction. The holding member is a member that receives and holds the formed sleeve member 30. When the roller is rotated and the holding member is rotated to convey the sleeve member 30, the position adjustment device 250 changes the relative position of the holding member with respect to the roller along the rotation axis direction of the roller, thereby expanding the distance between the sleeve members 30 adjacent to each other in the conveying direction of the sleeve member.

By adjusting the positions of the first sleeve member 30R and the second sleeve member 30L by the position adjustment devices 245 and 250 in this manner, the first sleeve member 30R and the second sleeve member 30L are transported to different transport paths during transport, and are transported to different places. Specifically, the first sleeve member 30R is conveyed to the sleeve member superimposing apparatus 260, and the second sleeve member 30L is conveyed to the sleeve member superimposing apparatus 270.

The description of the processing of the first sheet W1 is returned. Reference is now made mainly to fig. 5, 10 and 13.

The sleeve member superimposing apparatus 260 (see fig. 13) superimposes the conveyed first sheet W1 on the first sleeve member 30R (step A7 in fig. 10). Step A7 of fig. 10 is an example of the first overlapping step. The sleeve member superimposing apparatus 260 superimposes the first sleeve member 30R on the conveyed first sheet W1 so that the first sleeve member 30R is disposed at a predetermined position on the outer surface of the front member 10 in the produced garment 1.

In addition, when the first sheet W1 is overlapped with the first sleeve member 30R, the sleeve member overlapping device 260 heats a portion of the right edge portion of the first sheet W1 to which the hot melt adhesive is applied by the adhesive applying device 160. As a result, the first sheet W1 and the first sleeve member 30R are joined. In other words, step A7 in fig. 10 is also a part of the joining step of joining the first sheet W1 and the sleeve member 30.

The sleeve member superimposing apparatus 270 (see fig. 13) superimposes the conveyed first sheet W1 and the second sleeve member 30L (step A8 in fig. 10). Step A8 of fig. 10 is an example of the first overlapping step. The sleeve member superimposing apparatus 260 superimposes the second sleeve member 30L on the conveyed first sheet W1 so that the second sleeve member 30L is disposed at a predetermined position on the outer surface of the front member 10 in the produced garment 1.

In addition, when the first sheet W1 and the second sleeve member 30L are overlapped, the sleeve member overlapping device 260 heats the portion of the left edge portion of the first sheet W1 to which the hot melt adhesive is applied by the adhesive applying device 160. As a result, the first sheet W1 and the second sleeve member 30L are joined. In other words, step A8 in fig. 10 is also a part of the joining step of joining the first sheet W1 and the sleeve member 30.

Here, the description of the processing performed on the first sheet W1 is interrupted again, and the processing performed on the second sheet W2 will be described mainly with reference to fig. 7, 12, and 14.

The second sheet conveying apparatus 310 (see fig. 14) conveys the second sheet W2 fed from a raw material roll (not shown) using, for example, a plurality of rollers (step C1 in fig. 12). The step C1 in fig. 12 is an example of a second conveying step of conveying the second sheet W2 for forming the rear member 20 of the other of the front body and the rear body (hereinafter referred to as the rear body). Although the detailed description is omitted here, the second sheet W2 may be a sheet formed by stacking a plurality of sheets, and the step of manufacturing the garment 1 may include a step of manufacturing the second sheet W2 formed by stacking a plurality of sheets.

The sheet joining device 320 (see fig. 13) joins the neck sheet piece 25, which is cut out of a sheet (not shown) fed from a roll (not shown) of raw material, to the second sheet W2 (step C2 in fig. 12) conveyed by the second sheet conveying device 310. The joining method may be welding or bonding using an adhesive, and may be appropriately selected. The sheet joining device 320 joins the neck panel 25 to the conveyed second sheet W2 so that the neck panel 25a (the member left in the rear member 20 after the neck panel 25 is cut together with the second sheet W2 in the subsequent step) is disposed at a predetermined position around the neckline 24 on the inner surface of the rear member 20 in the produced garment 1. The shape of the neck surrounding sheet material pieces 25 may be appropriately determined, for example, rectangular.

The slit device 330 (see fig. 14) forms a slit in the conveyance direction of the second sheet W2 in the middle portion of the conveyed second sheet W2 in the width direction of the second sheet W2 (the direction orthogonal to the conveyance direction of the second sheet W2) (step C3 in fig. 12). The step C3 in fig. 12 is an example of the third forming step. The second sheet W2 having the slit formed therein by the slit device 330 is separated into a second right sheet W2a and a second left sheet W2b and conveyed.

The second right sheet W2a is subjected to the following processing.

The neck strap engaging device 340 engages the second neck strap 22b to the second right side sheet W2a that is conveyed (step C4 in fig. 12). The neck strap joining device 340 joins the second neck strap 22b to the conveyed second right sheet W2a so that the second neck strap 22b is disposed at a predetermined position on the outer surface of the rear member 20 in the manufactured garment 1. In addition, the neck strap engaging device 340 is functionally identical to the front strap engaging devices 140, 150 except for the engagement position of the straps, the length of the engaged straps, and the like. Here, in order to avoid redundancy of description, detailed description of the neck strap engaging device 340 is omitted.

The waist belt joining device 350 joins the waist inner belt 21b to the second right side sheet W2a that is conveyed (step C5 in fig. 12). The waist belt joining device 350 joins the waist inner belt 21b to the conveyed second right sheet W2a so that the waist inner belt 21b is disposed at a predetermined position on the inner surface of the rear member 20 in the manufactured garment 1. In addition, the waistband engagement device 350 is functionally identical to the front band engagement devices 140, 150, except that the engagement location of the bands, the length of the engaged bands, etc. Here, in order to avoid redundancy of description, detailed description of the neck strap engaging device 340 is omitted.

The face fastener joining device 360 joins the face fastener 22C to the conveyed second right side sheet W2a (step C6 in fig. 12). The panel joining device 360 joins the panel 22c to the conveyed second right sheet W2a so that the panel 22c is disposed at a predetermined position on the inner surface of the rear member 20 in the manufactured garment 1.

The adhesive applying device 370 (see fig. 14) applies an adhesive to the outer surface of the conveyed second right sheet W2a (the surface that becomes the outer surface of the front member 10 when the garment 1 is formed) at a position where the first sleeve member 30R is joined (step C7 in fig. 12). Specifically, the adhesive applying device 370 applies an adhesive to a position of the right edge portion of the second right sheet W2a that is in contact with the first sleeve member 30R in a subsequent process. Although not limited thereto, the adhesive applied by the adhesive applying device 370 is a hot melt adhesive.

Next, the processing performed on the second left sheet W2b will be described. Although steps C8 to C10 are described after steps C4 to C7 for convenience of illustration, this does not mean that steps C8 to C10 are performed after steps C4 to C7. Steps C4 to C and steps C8 to C10 may be performed in parallel.

The waist belt joining device 380 joins the waist outer belt 21a to the second left side sheet W2b that is conveyed (step C8 in fig. 12). The waist belt joining device 380 joins the waist outer belt 21a to the conveyed second left side sheet W2b so that the waist outer belt 21a is disposed at a predetermined position on the outer surface of the rear side member 20 in the manufactured garment 1. In addition, the waistband engagement device 380 is functionally identical to the front band engagement devices 140, 150, except that the engagement location of the bands, the length of the engaged bands, etc. Here, in order to avoid redundancy of description, detailed description of the waistband joining device 380 is omitted.

The neck strap engagement device 390 engages the first neck strap 22a with the second left side sheet W2b that is conveyed (step C9 in fig. 12). The neck strap joining device 390 joins the first neck strap 22a to the conveyed second left side sheet W2b so that the first neck strap 22a is disposed at a predetermined position on the outer surface of the rear side member 20 in the manufactured garment 1. In addition, the neck strap engaging device 390 is functionally identical to the front strap engaging devices 140, 150 except for the engagement position of the straps, the length of the engaged straps, and the like. Here, in order to avoid redundancy of description, detailed description of the neck strap engagement device 390 is omitted.

The adhesive applying device 400 (see fig. 14) applies an adhesive to the outer surface of the conveyed second left sheet W2b (the surface that becomes the outer surface of the front member 10 when the garment 1 is formed) at a position where the second sleeve member 30L is joined (step C10 in fig. 12). Specifically, the adhesive applying device 400 applies an adhesive to a position of the left edge portion of the second left sheet W2b that is in contact with the second sleeve member 30L in a subsequent process. Although not limited thereto, the adhesive applied by the adhesive applying apparatus 400 is a hot melt adhesive.

The description of the processing performed on the first sheet W1 is returned again. Hereinafter, the processing performed on the first sheet W1 will be described mainly with reference to fig. 5, 10, and 15.

The second sheet overlapping device 410 (see fig. 15) overlaps the conveyed first sheet W1 and the conveyed second right sheet W2a (second sheet W2) such that the first sleeve member 30R overlapped with the first sheet W1 is disposed between the first sheet W1 and the second right sheet W2a (step A9 in fig. 10). Step A9 in fig. 10 is an example of the second overlapping step.

In addition, the second sheet overlapping device 410 heats the portion of the right edge portion of the second right sheet W2a to which the hot melt adhesive is applied by the adhesive applying device 370 when overlapping the first sheet W1 and the second right sheet W2 a. As a result, the second right sheet W2a and the first sleeve member 30R are joined. In other words, step A9 of fig. 10 is also a part of the joining process of joining the second sheet W2 (second right sheet W2 a) and the sleeve member 30.

The second sheet superimposing apparatus 420 (see fig. 15) superimposes the conveyed first sheet W1 and the conveyed second left sheet W2b (second sheet W2) so that the second sleeve member 30L superimposed on the first sheet W1 is arranged between the first sheet W1 and the second left sheet W2b (step a10 in fig. 10). Step a10 in fig. 10 is an example of the second overlapping step.

In addition, the second sheet overlapping device 420 heats the portion of the left edge portion of the second left sheet W2b to which the hot melt adhesive is applied by the adhesive applying device 400 when overlapping the first sheet W1 and the second left sheet W2 b. As a result, the second left sheet W2b and the second sleeve member 30L are joined. In other words, step a10 of fig. 10 is also a part of the joining process of joining the second sheet W2 (second left sheet W2 b) and the sleeve member 30.

As shown in the enlarged double-dot chain line of fig. 15, the first sheet W1, the first sleeve member 30R, the second sleeve member 30L, and the second sheet W2 are arranged in this order through the steps of step A9 and step a 10. Further, through the steps of step A9 and step a10, the first sleeve member 30R and the second sleeve member 30L are placed between the outer surface of the first sheet W1 (the surface that becomes the outer surface of the front side member 10 when the garment 1 is formed) and the outer surface of the second sheet W2 (the surface that becomes the outer surface of the rear side member 20 when the garment 1 is formed).

The first sheet W1 and the second sheet W2 overlapped in the steps A9 and a10 are conveyed further downstream.

In the garment manufacturing system 100, a single garment 1 is formed by the region Z of the first sheet W1 and the second sheet W2 that are conveyed in a stacked state. As shown in fig. 5, the region Z is a region surrounded by the line segment X1, the line segment X2, and both edge portions in the direction orthogonal to the conveyance direction of the first sheet W1 and the second sheet W2. The line segments X1 and X2 are straight lines extending in the width direction of the first sheet W1 and the second sheet W2, which are orthogonal to the longitudinal direction of the first sheet W1 and the second sheet W2. The line segment X1 and the line segment X2 are arranged to be separated by a length L3 (see fig. 3) which is the entire length of the garment 1.

The garment 1 is manufactured from the material of the majority of the zones Z of the first web W1 and the second web W2. Of the first sheet W1 and the second sheet W2 of the region Z, only the portion surrounded by the virtual line X3 and the line segment X1 and the portion surrounded by the virtual line X4 and the line segment X1 become the scraps, wherein the virtual line X3 is a virtual line drawn at a position of a collar (the collar 14 of the front side member 10 and the collar 24 of the rear side member 20) of the garment 1 when the garment 1 is formed, and the virtual line X4 is a virtual line drawn at a position of an inclined portion (the inclined portion 16a of the shoulder portion 16 of the front side member 10 and the inclined portion 26a of the shoulder portion 26 of the rear side member 20) of the shoulder portion 1 when the garment 1 is formed. The line segment X1 here is a line segment drawn at a position that becomes a horizontal portion of the shoulder portion of the garment 1 (the horizontal portion 16b of the shoulder portion 16 of the front side member 10 and the horizontal portion 26b of the shoulder portion 26 of the rear side member 20) when the garment 1 is formed. The line segment X2 is a line segment drawn at a position of the hem (the hem 18 of the front side member 10 and the hem 28 of the rear side member 20) of the garment 1 when the garment 1 is formed.

In steps a11 and a12 described below, in order to form 1 piece of clothing 1 from a region Z in which the first sheet W1 and the second sheet W2 are conveyed in an overlapped state, in the region Z, the first sheet W1 and the second sheet W2 are partially joined in accordance with the outer edge shape of the clothing 1, and the first sheet W1 and the second sheet W2 are partially joined in accordance with the outer edge shape of the clothing 1. That is, the steps a11 and a12 are an example of the second forming step.

In step a11, the first sheet W1 and the second sheet W2 are partially joined by the body edge joining device 180 disposed downstream of the second sheet overlapping device 420 in the conveyance direction of the first sheet W1 and the second sheet W2.

Specifically, the body edge joining device 180 joins the first sheet W1 and the second sheet W2 (the portion shown by the thick solid line) at a portion that swings downward from the underarm portion of the garment 1 when the garment 1 is formed and at a portion that becomes the shoulder portion of the garment 1 when the garment 1 is formed.

In other words, the body edge portion joining device 180 joins the portions of the first sheet W1 and the second sheet W2 that are in direct contact with the first sheet W1 and the second sheet W2, of the two edge portions of the first sheet W1 and the second sheet W2 in the direction orthogonal to the conveyance direction. The body edge joining device 180 joins a portion of the first sheet W1 that becomes the shoulder portion 16 of the front side member 10 when formed into the garment 1 and a portion of the second sheet W2 that becomes the shoulder portion 26 of the rear side member 20 when formed into the garment 1.

The joining method of the first sheet W1 and the second sheet W2 by the body edge joining device 180 may be heat welding or ultrasonic welding. The joining method of the first sheet W1 and the second sheet W2 by the body edge joining device 180 may be bonding using an adhesive.

In step a12, the body edge portion cutting device 190 cuts the first sheet W1 and the second sheet W2 in accordance with the shapes (corresponding to the shapes) of the inclined portions of the shoulder portions (the inclined portion 16a of the shoulder portion 16 of the front side member 10 and the inclined portion 26a of the shoulder portion 26 of the rear side member 20) and the neckline (the neckline 14 of the front side member 10 and the neckline 24 of the rear side member 20) of the outer edge of the garment 1 in the region Z of the first sheet W1 and the second sheet W2 that are conveyed in the overlapped state.

When the detailed description is made with reference to the drawings, in step a12, the body edge cutting device 190 cuts the portion shown by the thick line in fig. 9, which becomes the inclined portion 16a of the shoulder portion 16 of the front side member 10 and the inclined portion 26a of the shoulder portion 26 of the rear side member 20 when the garment 1 is formed. The body edge cutting device 190 cuts the portion shown by the thick line in fig. 9, which becomes the neckline 14 of the front side member 10 and the neckline 24 of the rear side member 20 when the garment 1 is formed. The body edge cutting device 190 cuts a portion of the line segment 17 shown by a thick line in fig. 9, wherein the line segment 17 connects one end of the neckline 14 of the front member 10 and the neckline 24 of the rear member 20 with the other end of the neckline 14 of the front member 10 and the neckline 24 of the rear member 20. The scraps (the portion surrounded by the portion of the neck opening 14 of the front side member 10 and the neck opening 24 of the rear side member 20 and the line segment 17 when the garment 1 is formed) generated at this time are collected by a scrap collecting device (not shown).

On the other hand, the body edge cutting device 190 does not cut the portions indicated by the broken lines in fig. 9, which become the horizontal portion 16b of the shoulder portion 16 of the front side member 10 and the horizontal portion 26b of the shoulder portion 26 of the rear side member 20 when formed into the garment 1. By not cutting the portions of the horizontal portion 16b of the shoulder portion 16 that become the front side member 10 and the horizontal portion 26b of the shoulder portion 26 of the rear side member 20 when the garment 1 is formed, even if the body edge portion cutting device 190 cuts the first sheet W1 and the second sheet W2, the first sheet W1 and the second sheet W2 located downstream of the portion cut by the body edge portion cutting device 190 and the first sheet W1 and the second sheet W2 located upstream of the portion cut by the body edge portion cutting device 190 are in a connected state. Therefore, when the first sheet W1 and the second sheet W2 are conveyed downstream of the portion cut by the body edge cutting device 190, the first sheet W1 and the second sheet W2 can also be conveyed upstream of the portion cut by the body edge cutting device 190.

In step a12, the body edge cutting device 190 may not cut a portion of the line segment 17, as shown by a broken line in fig. 10.

The first sheet W1 and the second sheet W2 processed by the edge portion cutting device 190 are conveyed further downstream.

The tucking device 195 (see fig. 15) tucks both ends of the first sheet W1 and the second sheet W2, which are processed by the edge portion cutting device 190 and conveyed in a superimposed state, in a direction orthogonal to the conveying direction (third direction D3, see fig. 5) of the first sheet W1 and the second sheet W2, into the inner side in the third direction (step a13 in fig. 10). As a result, the width of the conveyed first sheet W1 and second sheet W2 in the width direction orthogonal to the conveying direction is reduced.

The first sheet W1 and the second sheet W2 folded by the folding device 195 are conveyed further downstream, and the separating device 200 disposed on the downstream side of the folding device 195 cuts out the first sheet W1 and the second sheet W2 (in other words, the portions for manufacturing the region Z of the garment 1) of the portion of the one article of garment 1 from the first sheet W1 and the second sheet W2 conveyed in the overlapped state (step a14 of fig. 10). In other words, the separating apparatus 200 separates the garment 1 formed in the second forming process (step a11 and step a 12) from the first sheet W1 and the second sheet W2. The step a14 is an example of the separation step, and the step a14 is performed such that the piece of clothing 1 is separated from the first sheet W1 and the second sheet W2, and is independent of the first sheet W1 and the second sheet W2. The scraps produced at this time are recovered by a scrap recovery device, not shown.

After step a14, in order to further achieve compactness of the garment 1, the garment manufacturing system 100 may also have means to further fold the garment 1. A detailed description thereof will be omitted.

(3) Features (e.g. a character)

The features of the method for manufacturing the garment 1 according to the above embodiment will be described below.

(3-1)

The method for manufacturing the garment 1 according to the above embodiment includes: the first conveying process (step A1), the second conveying process (step C1), the first forming process (steps B5, B6, B7), the first overlapping process (steps A7, A8), the second overlapping process (steps A9, a 10), the second forming process (steps a11, a 12), and the separating process (step a 14). In the first conveying step, a first sheet W1 is conveyed, wherein the first sheet W1 is used to form a front side member 10 (precursor) as an example of the first member. In the second conveying step, a second sheet W2 is conveyed, wherein the second sheet W2 is used to form a rear member 20 (rear body) as an example of the second member. In the first forming step, the third sheet W3 to be conveyed and the fourth sheet W4 to be conveyed are overlapped, and the third sheet W3 and the fourth sheet W4 to be conveyed in an overlapped state are partially joined and cut at a predetermined position, thereby forming the tubular sleeve member 30. In the first overlapping step, the conveyed first sheet W1 is overlapped with the sleeve member 30. In the second overlapping step, the conveyed first sheet W1 and the conveyed second sheet W2 are overlapped so that the sleeve member 30 overlapped with the first sheet W1 is arranged between the first sheet W1 and the second sheet W2. In particular, in the above-described embodiment, in the second overlapping step, the first conveyed sheet W1 and the second conveyed right sheet W2a are overlapped such that the first sleeve member 30R overlapped with the first sheet W1 is arranged between the first sheet W1 and the second right sheet W2 a. In the above embodiment, in the second overlapping step, the first conveyed sheet W1 and the second conveyed left sheet W2b are overlapped such that the second sleeve member 30L overlapped with the first sheet W1 is arranged between the first sheet W1 and the second left sheet W2 b. In the second forming step, the first sheet W1 and the second sheet W2 conveyed in the overlapped state are partially joined in accordance with the outer edge shape of the garment 1. In the second forming step, the first sheet W1 and the second sheet W2 conveyed in the overlapped state are partially cut according to the outer edge shape of the garment 1. In the separation step, the clothing formed in the second forming step is separated from the first sheet W1 and the second sheet W2.

In the method for manufacturing the garment 1 according to the above embodiment, the garment 1 can be manufactured by relatively simple steps, and the garment 1 can be manufactured efficiently.

In the method of manufacturing the garment 1 according to the above embodiment, the sleeve member 30 is disposed between the first sheet W1 for forming the front member 10 and the second sheet W2 for forming the rear member 20, and therefore, the sleeve member 30 and the portion that becomes the outer surface of the front member 10 can be covered with the rear member 20. As a result, in the method for manufacturing the garment 1 according to the above embodiment, the occurrence of contamination of the outer surface of the front side member 10 or the sleeve member 30 of the manufactured garment 1 due to contact by a human hand or the like can be suppressed, and a garment excellent in hygiene can be manufactured.

Further, in the method for manufacturing the garment 1 according to the above embodiment, since the inner surface side of the rear side member 20 is exposed to the outside in the garment 1 before wearing, the occurrence of contamination of the outer surface of the rear side member 20 due to contact with a human hand or the like can be suppressed, and the garment excellent in hygiene can be manufactured.

(3-2)

The method of manufacturing the garment 1 according to the above embodiment includes a third forming step (step C3). In the third forming step, a slit is formed in the second sheet W2 in the direction of conveying the second sheet.

In the method for manufacturing the garment 1 according to the above embodiment, before the garment 1 is worn, contamination of the sleeve member 30 and the portion that becomes the outer surface of the front side member 10 (front body) can be suppressed in the rear side member 20 (rear body), and the rear side member 20 can be easily disposed on the rear side of the body when the garment 1 is worn. In summary, in the method for manufacturing the clothing article 1 according to the above embodiment, the clothing article 1 excellent in hygiene and easy to wear can be manufactured.

(3-3)

In the garment 1 manufactured by the manufacturing method of the garment 1 of the above embodiment, the opening size of the cuffs 32 of the sleeve members 30 is smaller than the opening size of the arm holes 34 of the sleeve members 30. In the sleeve member forming step, the first sleeve member 30R and the second sleeve member 30L are alternately formed from the third sheet W3 and the fourth sheet W4 conveyed in the first direction D1 in the overlapped state. The first sleeve member 30R is a sleeve member 30 in which cuffs 32 are arranged on one end side in the second direction D2 orthogonal to the first direction D1, among the third sheet W3 and the fourth sheet W4 conveyed in the first direction D1 in an overlapped state. The second sleeve member 30L is a sleeve member 30 in which cuffs 32 are arranged on the other end side (opposite side to the first sleeve member 30R) of the second direction D2 orthogonal to the first direction D1 in the third sheet W3 and the fourth sheet W4 conveyed in the first direction D1 in the overlapped state.

The opening size of the cuffs 32 of the sleeve members 30 of the garment 1 manufactured by the method of manufacturing the garment 1 of the above embodiment is small and the opening size of the arm holes 34 is large. Therefore, the clothing manufactured by this manufacturing method is easy to move the arm when worn, and the cuffs 32 are not easy to interfere with the work.

In the third sheet W3 and the fourth sheet W4 that are conveyed in the overlapped state, the smaller number of sheets of the first sleeve member 30R may be disposed at one end (referred to as a first end) in the second direction D2, and the arm hole 34 that requires the larger number of sheets may be disposed at the other end (referred to as a second end) in the second direction D2. On the other hand, in the third sheet W3 and the fourth sheet W4 that are conveyed in the overlapped state, the smaller number of sheets in the second sleeve member 30L can be arranged at the second end portion in the second direction D2, and the arm hole 34 that requires the larger number of sheets can be arranged at the first end portion in the second direction D2. Therefore, compared with the case where only the sleeve member 30 corresponding to the first sleeve member 30R or the second sleeve member 30L is continuously manufactured from the third sheet W3 and the fourth sheet W4, the amount of material required for manufacturing the sleeve member 30 can be suppressed by adopting the manufacturing method of the garment 1.

(3-4)

The method for manufacturing the garment 1 according to the above embodiment includes a first disposing step (step B2) and a second disposing step (step B4). In the first disposing step, the expansion and contraction member E is disposed at both end portions of the third sheet W3 to be conveyed in the direction orthogonal to the direction in which the third sheet W3 is conveyed. In the second disposing step, the extension and contraction member E is disposed at both end portions of the fourth sheet W4 to be conveyed in the direction orthogonal to the direction in which the fourth sheet W4 is conveyed.

In this method of manufacturing the garment 1, since the stretchers E are disposed at both end portions of the third sheet W3 and the fourth sheet W4 in the direction orthogonal to the conveyance direction of the third sheet W3 and the fourth sheet W4, respectively, the stretchers E can be provided at the cuffs 32 of the sleeve members 30. Therefore, in the garment 1 manufactured by this manufacturing method, the cuffs 32 can be tightened by the stretch elements E, so that the cuffs 32 do not easily interfere with the work, and foreign matter does not easily enter the garment 1 from the cuffs 32.

(3-5)

In the method of manufacturing the garment 1 according to the above embodiment, the expansion element E is disposed at both the portion to be the cuff 32 of the sleeve member 30 and the portion to be the arm hole 34 of the sleeve member 30. The method for manufacturing the garment 1 includes a cutting step of cutting the stretchable material E attached to the portion of the arm hole 34 serving as the sleeve member 30.

If the extension and contraction member E is present in the arm hole 34 portion of the sleeve member 30, wrinkles may occur in the sheets W3 and W4 forming the sleeve member 30 or the first sheet W1 or the second sheet W2 to which the sleeve member 30 is attached during the manufacturing process of the garment 1, and there is a possibility that the garment 1 may not be manufactured aesthetically. If the extension and contraction member E is present in the arm hole 34 portion of the sleeve member 30, the wearing of the garment 1 may be hindered.

In contrast, in this method for manufacturing the garment 1, since the expansion element E attached to the arm hole 34 portion of the sleeve member 30 is cut, the expansion element E can be prevented from interfering with the manufacture of the garment 1 or with the wearing of the garment 1.

(3-6)

The method for manufacturing the garment 1 according to the above embodiment includes the joining step (steps A7, A8, A9, a 10). The joining step is performed before joining the first sheet W1 and the second sheet W2. In the joining step, the first sheet W1 is joined to the sleeve member 30, and the second sheet W2 is joined to the sleeve member 30.

In this method for manufacturing the garment 1, misalignment of the sleeve member 30 with respect to the first sheet W1 and the second sheet W2 during the manufacturing process can be suppressed.

(3-7)

In the method of manufacturing the garment 1 according to the above embodiment, the shoulder portions (the shoulder portions 16 of the front side member 10 and the shoulder portions 26 of the rear side member 20) of the garment 1 are disposed at positions closer to the hem (the hem 18 of the front side member 10 and the hem 28 of the rear side member 20) of the garment 1 than the end portions (16 c, 26 c) of the shoulder portions of the garment 1 on the side of the neckline (the neckline 14 of the front side member 10 and the neckline 24 of the rear side member 20) of the garment 1. In the second forming step, the first sheet W1 and the second sheet W2 are cut in accordance with the shape of at least a part of the shoulder portion of the outer edge of the garment 1 (the inclined portion 16a of the shoulder portion 16 of the front side member 10 and the inclined portion 26a of the shoulder portion 26 of the rear side member 20).

The garment 1 manufactured by this manufacturing method has a shape in which the shoulder portion becomes lower from the neckline side to the sleeve portion. Therefore, the garment 1 manufactured by this manufacturing method is easy to fit.

(3-8)

The method for manufacturing the garment 1 according to the above embodiment includes a folding step (step a 13). The folding step is a step after the second forming step (steps a11 and a 12), and is performed on the first sheet W1 and the second sheet W2 conveyed in the third direction D3 in an overlapped state before the separating step (step a 14). In the folding step, both ends of the first sheet W1 and the second sheet W2 in the direction orthogonal to the third direction D3 are folded inward in the third direction D3.

In this method for manufacturing the garment 1, the manufactured garment 1 can be made compact.

(4) Modification examples

A modification of the above embodiment will be described below. The following modifications may be appropriately combined within a range not contradicting each other.

(4-1) Modification A

The positions and the number of the strapping tapes and the surface fasteners provided on the front side member 10 and the rear side member 20 are merely examples, and may be appropriately changed. The strapping tape and the surface fastener may be omitted appropriately.

(4-2) Modification B

In the step C3 of the above embodiment, a slit is formed in the second sheet W2 in the direction in which the second sheet W2 is conveyed.

However, the present invention is not limited thereto, and instead of the slit, an eye may be formed in the second sheet W2 in the direction in which the second sheet W2 is conveyed in the step C3. In addition, in this case, the second sheet W2 is not separated. Accordingly, the steps C4 to C10 in fig. 12 are performed for one sheet (second sheet W2). In this case, as in step A9 and step a10 of fig. 10, the second right sheet W2a and the second left sheet W2b are not overlapped with each other on the first sheet W1 twice, but the second sheet W2 is overlapped with the first sheet W1 in one step. In addition, the garment 1 manufactured in this case is not configured such that the right rear side member 20R and the left rear side member 20L are overlapped as in the above embodiment. When wearing the clothing 1 (see fig. 16) in which the eyelets 23 are formed instead of slits, the back member 20 is disposed on the back side of the wearer after the eyelets 23 are cut, for example, to assist the wearer wearing the clothing 1.

In addition, the step C3 may be omitted. In this case, when wearing the garment 1, an auxiliary person wearing the garment 1 or the like is assisted to cut the rear side member 20 at a predetermined position in the up-down direction (for example, cut the rear side member 20 along a cut line drawn on the rear side member 20), and the rear side member 20 is disposed on the back side of the wearer.

(4-3) Modification C

In the above embodiment, the first sheet W1 and the sleeve member 30 are overlapped, and then the first sheet W1 and the second sheet W2 are overlapped. However, the present invention is not limited thereto, and the second sheet W2 and the sleeve member 30 may be overlapped, and then the second sheet W2 and the first sheet W1 may be overlapped.

(4-4) Modification D

In the garment 1 manufactured by the manufacturing method of the above embodiment, the opening size of the cuffs 32 of the sleeve member 30 is smaller than the opening size of the arm holes 34 of the sleeve member 30. However, the opening size of the cuff 32 of the sleeve member 30 is not limited to this, and may be the same as the opening size of the arm hole 34 of the sleeve member 30. In other words, the thickness of the sleeve member 30 may be the same.

(4-5) Modification E

In the manufacturing method of the above embodiment, the sleeve member 30 as the right sleeve and the sleeve member 30 as the left sleeve are manufactured from the third sheet W3 and the fourth sheet W4. However, the present invention is not limited thereto, and the sleeve member 30 serving as the right sleeve may be manufactured from a pair of sheets, and the sleeve member 30 serving as the left sleeve may be manufactured from a pair of sheets different from the sleeve member 30 serving as the right sleeve. In other words, the sleeve member 30 as the right sleeve and the sleeve member 30 as the left sleeve may be manufactured by different devices. However, in this case, a manufacturing apparatus for the right sleeve and a manufacturing apparatus for the left sleeve are required, respectively, which may increase the cost of the garment manufacturing system.

(4-6) Modification F

In the manufacturing method of the above embodiment, in steps A7, A8, A9, and a10, the joining of the first sheet W1 and the sleeve member 30 and the joining of the second sheet W2 and the sleeve member 30 are completed.

However, the present invention is not limited thereto, and in steps A7, A8, A9, and a10, temporary fixation of the first sheet W1 to the sleeve member 30 and temporary fixation of the second sheet W2 to the sleeve member 30 may be performed. In step a11, when the first sheet W1 and the second sheet W2 are joined, the first sheet W1 and the sleeve member 30 may be joined and the second sheet W2 and the sleeve member 30 may be joined. In addition, as the joining means, even in the case of selecting the heat welding or the ultrasonic welding, the third sheet W3 and the fourth sheet W4 can be prevented from being welded by adjusting the output thereof, and the first sheet W1 and the second sheet W2 can be joined with the sleeve member 30.

(4-7) Modification G

The method of manufacturing the garment 1 described in the above embodiment is only an example of the present invention, and may be modified as appropriate.

For example, in the above embodiment, the expansion element E is attached to the third sheet W3 and the fourth sheet W4, but this step may be omitted.

Further, for example, in the above-described embodiment, after the folding device 195 folds the garment 1, the garment 1 is separated from the first sheet W1 and the second sheet W2, but conversely, the garment 1 may be folded after the garment 1 is separated from the first sheet W1 and the second sheet W2.

(4-8) Modification H

In the garment 1 described in the above embodiment, the shoulder portions 16, 26 have the inclined portions 16a, 26a, but the garment is not limited thereto. The shoulder portions 16, 26 may be entirely formed of the horizontal portions 16b, 26 b.

(4-9) Modification I

In the method of manufacturing the clothing according to the above embodiment, the sleeve member 30 having the cuffs 32 arranged on one end side in the second direction D2 orthogonal to the first direction D1 and the sleeve member 30 having the cuffs 32 arranged on the other end side in the second direction D2 are alternately formed by cutting the third sheet W3 and the fourth sheet W4 (joining/cutting of only two sheets) conveyed in the first direction D1.

The method of manufacturing the garment of the present disclosure is not limited in this manner. For example, in the method of manufacturing the clothing of the present disclosure, the third sheet W3 and the fourth sheet W4 that are conveyed in the first direction D1 may be cut (by joining/cutting the two sheets), and the sleeve member 30 having the cuffs 32 disposed on one end side in the second direction D2 orthogonal to the first direction D1 may be temporarily formed. After the formation of the sleeve member 30, the conveyance posture of the sleeve member 30 may be changed while the sleeve member 30 is conveyed so that the sleeve member 30 having the cuffs 32 arranged on one end side in the direction orthogonal to the conveyance direction and the sleeve member 30 having the cuffs 32 arranged on the other end in the direction orthogonal to the conveyance direction are alternately arranged along the conveyance direction.

As a result of this structure, the sleeve member for the right sleeve and the sleeve member 30 for the left sleeve can be manufactured from the third sheet W3 and the fourth sheet W4.

(4-10) Modification J

In the manufacturing method of the above embodiment, the sleeve edge portion cutting device 240 joins the joining portions of the third sheet W3 and the fourth sheet W4 by the sleeve edge portion joining device 230, and cuts each of the joining portions at the center thereof in the extending direction of the joining portions. As shown in fig. 17, at the time point when this process is completed, the joining portion J (hatched portion) of the third sheet W3 and the fourth sheet W4 is protruded to the outside of the sleeve member 30.

In consideration of the fact that, in the sleeve member 30, if the garment 1 is manufactured in a state in which the joining portions J of the third sheet W3 and the fourth sheet W4 are protruded outward (if the garment 1 is manufactured in a form in which the joining portions J are arranged outward when worn), when the garment 1 is used, there is a possibility that the joining portions J may be caught by, contact with, or the like of the viscera of the patient during an operation, for example, the joining portions J may inadvertently damage the viscera of the patient. In addition, the appearance of such a garment 1 may also deteriorate.

From this point of view, the method of manufacturing the garment 1 may include a turn-over step. The turning step is performed before the first forming step of forming the tubular sleeve member 30 and the first overlapping step of overlapping the sleeve member 30 formed in the first forming step with the first sheet. The turning step is a step of turning the sleeve member 30 so that the surface of the sleeve member 30 disposed on the outer side is disposed on the inner side in the first forming step.

Specifically, the turning-over step is a step of: for example, in the sleeve member formed in the first forming step and having the first surface F1 (the side where the joint J is exposed) directed outward as shown in fig. 17, the cuff 32 side is gripped, the cuff 32 is moved so that the cuff 32 passes through the opening formed between the third sheet W3 and the fourth sheet W4 on the arm hole 34 side, and the first surface F1 is disposed inside the tubular sleeve member 30.

An example of the process of forming the sleeve member 30 including the turn-up process will be described with reference to fig. 18. Here, as shown in modification I, a case will be described in which the sleeve member 30 having the cuffs 32 disposed on one end side in the second direction D2 is formed by joining/cutting only the third sheet W3 and the fourth sheet W4 that are conveyed in the first direction D1.

In the process of forming the sleeve member 30 described herein, the process is the same as the process of steps B1 to B6 in fig. 18 except for the process of forming the sleeve member 30 and the steps B2 and B4 in the above embodiment, and therefore only the differences will be described herein.

Here, since the sleeve member 30 having the cuffs 32 arranged on one end side in the second direction D2 is formed by joining/cutting only the third sheet W3 and the fourth sheet W4, it is not necessary to arrange the stretchers E on both ends in the second direction D2 in the steps B2 and B4, and it is only necessary to arrange the stretchers E on the side serving as the cuffs 32 in the second direction D2. In the manufacturing flow of fig. 18, since the expansion element E is not disposed on the arm hole 34 side, a step of cutting the expansion element E on the arm hole 34 side is not necessary.

In step B7a, as in the above embodiment, the sleeve edge portion cutting device 240 cuts the joined portions of the third sheet W3 and the fourth sheet W4, which are conveyed in the overlapped state in the first direction D1, by the sleeve edge portion joining device 230, respectively, at the center of the joined portions in the extending direction of the joined portions. However, it is preferable that the sleeve edge portion cutting device 240 does not cut the entirety of the third sheet W3 and the fourth sheet W4 in the second direction D2. Therefore, at the time point when the step B7a ends, the sleeve member 30 formed through the process of the step B7a is in a state of being connected to the sleeve member 30 adjacent in the first direction D1 on the arm hole 34 side in the second direction D2 (see fig. 18).

Next, at a position indicated by reference numeral R1 in fig. 18, the sleeve member 30 is turned over by a turning-over device (blower, suction machine, robot arm, or the like). The method of turning over is as described above.

Next, at a position indicated by reference numeral B7B in fig. 18, the sleeve members 30 adjacent to each other in the first direction D1 are cut by a cutting device, and the sleeve members 30 are in a mutually independent state.

After the completion of step B7B, the sleeve member 30 is transported by the position adjustment devices 245 and 250 to the next step (step B8 a) in the same manner as in step B8 of the above-described embodiment. However, in the flow shown in fig. 18, the sleeve member 30 having the cuffs 32 arranged on one end side in the second direction D2 is formed by joining/cutting only the third sheet W3 and the fourth sheet W4 (through the steps of step B6 and step B7 a). Therefore, in step B8a, as described in modification I, the position adjustment devices 245 and 250 also perform the process of changing the conveyance posture of the sleeve member 30 at the same time so that the sleeve member 30 having the cuff 32 disposed on one end side in the direction orthogonal to the conveyance direction and the sleeve member 30 having the cuff 32 disposed on the other end side in the direction orthogonal to the conveyance direction are alternately disposed along the conveyance direction of the sleeve member 30.

The process of forming the sleeve member 30 described with reference to fig. 18 is merely an example, and may be appropriately modified.

For example, the turning process R1 may be performed after the sleeve member 30 is formed as a separate member.

In the case where the third sheet W3 and the fourth sheet W4 (joining/cutting of only two sheets) conveyed in the first direction D1 are cut as described in the above embodiment, the sleeve member 30 having the cuffs 32 disposed on one end side in the second direction D2 orthogonal to the first direction D1 and the sleeve member 30 having the cuffs 32 disposed on the other end side in the second direction D2 are alternately formed, the turn-over step R1 may be employed.

Finally, the technical ideas that can be grasped from the above-described embodiment and other examples (modifications) are described below.

The method of manufacturing a garment of the first aspect of the invention comprises: a first conveying process, a second conveying process, a first forming process, a first overlapping process, a second forming process, and a separating process. In the first conveying step, a first sheet for forming the first member is conveyed. In the second conveying step, a second sheet for forming a second member is conveyed. The first member is one of the front body and the rear body, and the second member is the other of the front body and the rear body. In the first forming step, the third sheet to be conveyed and the fourth sheet to be conveyed are overlapped, and the third sheet to be conveyed and the fourth sheet to be conveyed in an overlapped state are partially joined and cut at a predetermined position, thereby forming a tubular sleeve member. In the first overlapping step, the conveyed first sheet is overlapped with the sleeve member. In the second overlapping step, the conveyed first sheet and the conveyed second sheet are overlapped so that the sleeve member overlapped with the first sheet is arranged between the first sheet and the second sheet. In the second forming step, the first sheet and the second sheet conveyed in the overlapped state are partially joined in accordance with the outer edge shape of the garment. In the second forming step, the first sheet and the second sheet conveyed in the overlapped state are partially cut according to the outer edge shape of the garment. In the separation step, the garment formed in the second forming step is separated from the first sheet and the second sheet.

In the method for manufacturing clothing according to the first aspect, clothing can be manufactured by relatively simple steps, and clothing can be manufactured efficiently.

In the method of manufacturing the garment according to the first aspect, the sleeve member is disposed between the first sheet for forming the first member and the second sheet for forming the second member, and therefore, the portion that becomes the outer surface (front surface) of the front body and the sleeve member can be covered with the rear body. As a result, in the method for manufacturing a garment according to the first aspect, it is possible to manufacture a garment excellent in hygiene that can suppress contamination of the outer surface of the front body or the sleeve member of the manufactured garment due to contact with a human hand or the like.

The method for manufacturing a garment according to the second aspect of the present invention further includes a third forming step in addition to the method for manufacturing a garment according to the first aspect. In the third forming step, a slit or an eye of needle is formed in the first sheet in the direction of conveying the first sheet. Or in the third forming step, a slit or an eye of needle is formed in the second sheet in the direction of conveying the second sheet.

In the method of manufacturing the garment of the second aspect, a slit or an eye of a needle may be formed in the member that becomes the rear body. As a result, the portion of the outer surface of the back body that becomes the front body and the sleeve member can be prevented from being contaminated before the garment is worn, and the back body can be easily disposed on the back side of the body when the garment is worn. In summary, in the method for manufacturing a garment according to the second aspect, a garment which is excellent in hygiene and easy to wear can be manufactured.

A third aspect of the present invention provides the method for manufacturing a garment according to the first or second aspect, wherein the opening size of the cuff of the sleeve member is smaller than the opening size of the arm hole of the sleeve member. In the sleeve member forming step, the first sleeve member and the second sleeve member are alternately formed from the third sheet and the fourth sheet that are conveyed in the first direction in the overlapped state. The first sleeve member is a sleeve member in which cuffs are arranged on one end side in a second direction orthogonal to the first direction, of a third sheet and a fourth sheet that are conveyed in the first direction in an overlapped state. The second sleeve member is a sleeve member in which cuffs are arranged on the other end side (the side opposite to the first sleeve member) in the second direction orthogonal to the first direction, of the third sheet and the fourth sheet conveyed in the first direction in an overlapped state.

In the sleeve member of the garment manufactured by the method for manufacturing a garment according to the third aspect, since the opening size of the cuff is small and the opening size of the arm hole is large, the method for manufacturing a garment according to the third aspect can manufacture a garment in which the arm is easily movable when the garment is worn and the cuff is not easily obstructed from working.

In the third sheet and the fourth sheet that are conveyed in the overlapped state, the smaller number of sheets in the first sleeve member may be disposed at one end (referred to as a first end) in the second direction, and the arm hole requiring the larger number of sheets may be disposed at the other end (referred to as a second end) in the second direction. On the other hand, in the third sheet and the fourth sheet that are conveyed in the overlapped state, the number of sheets in the second sleeve member can be reduced, and the cuffs can be arranged at the second end in the second direction, and the arm holes requiring a larger number of sheets can be arranged at the first end in the second direction. Therefore, in comparison with the case where only the first sleeve member or the second sleeve member is continuously produced from the third sheet and the fourth sheet, if the clothing production method of the third aspect is used, the occurrence of the scraps during the production of the sleeve member can be suppressed.

A method for manufacturing a garment according to a fourth aspect of the present invention further includes a first disposing step and a second disposing step in addition to the method for manufacturing a garment according to the third aspect. In the first disposing step, the expansion and contraction members are disposed at both end portions of the third sheet to be conveyed in a direction orthogonal to the direction in which the third sheet is conveyed. In the second disposing step, the stretchable material is disposed at both ends of the fourth sheet to be conveyed in a direction orthogonal to the direction in which the fourth sheet is conveyed.

In the method for manufacturing a garment according to the fourth aspect, the stretchable material is disposed on both ends of the third sheet and the fourth sheet in the direction perpendicular to the conveying direction of the third sheet and the fourth sheet, respectively, and therefore the stretchable material can be provided on the cuffs of the sleeve members. Therefore, in the garment manufactured by the manufacturing method according to the fourth aspect, the cuffs can be tightened by the stretch members, so that the cuffs do not easily interfere with the work, and foreign matter does not easily enter the garment from the cuffs.

In the method for manufacturing a garment according to a fifth aspect of the present invention, in the method for manufacturing a garment according to the fourth aspect, the stretchable material is disposed at both a portion to be a cuff of the sleeve member and a portion to be an arm hole of the sleeve member. The method for manufacturing the garment further includes a cutting step of cutting the stretchable material attached to the portion of the arm hole serving as the sleeve member.

If the expansion/contraction member is provided in the arm hole portion of the sleeve member, wrinkles may occur in the sheet forming the sleeve member or the first sheet or the second sheet to which the sleeve member is attached during the manufacturing process of the garment, and there is a possibility that the garment cannot be manufactured aesthetically. In addition, if the expansion and contraction member is present in the arm hole portion of the sleeve member, there is a possibility that the wearing of the garment may be hindered.

In contrast, in the method for manufacturing a garment according to the fifth aspect, since the expansion and contraction member attached to the arm hole portion of the sleeve member is cut, the expansion and contraction member can be prevented from interfering with the manufacture of the garment or with the wearing of the garment.

A method for manufacturing a garment according to a sixth aspect of the present invention is the method for manufacturing a garment according to any one of the first to fifth aspects, further comprising a joining step. The bonding step is performed before bonding the first sheet and the second sheet. In the joining step, the first sheet and the sleeve member are joined, and the second sheet and the sleeve member are joined.

In the method for manufacturing a garment according to the sixth aspect, misalignment of the sleeve member with respect to the first sheet and the second sheet during the manufacturing process can be suppressed.

A seventh aspect of the present invention provides the method for manufacturing a garment according to any one of the first to sixth aspects, wherein the end portion of the shoulder portion of the garment on the sleeve member side of the garment is disposed closer to the hem of the garment than the end portion of the shoulder portion of the garment on the neckline side of the garment. In the second forming step, the first sheet and the second sheet are cut in accordance with the shape of at least a part of the shoulder portion of the outer edge of the garment.

The shoulder portion of the garment manufactured by the manufacturing method according to the seventh aspect is formed in a shape that becomes lower from the neckline side toward the sleeve portion. Therefore, the garment manufactured by the manufacturing method of the seventh aspect is easy to fit.

A method for manufacturing a garment according to an eighth aspect of the present invention is the method for manufacturing a garment according to any one of the first to seventh aspects, further comprising a folding step. The folding step is a step after the second forming step, and is performed on the first sheet and the second sheet conveyed in the third direction in an overlapped state before the separating step. In the folding step, both end portions of the first sheet and the second sheet in a direction orthogonal to the third direction are folded inward in the third direction.

In the method for manufacturing a garment according to the eighth aspect, the manufactured garment can be made compact.

A ninth aspect of the present invention provides the method for manufacturing a garment according to any one of the first to eighth aspects, further comprising a turn-over step. The turning step is performed before the sleeve member formed in the first forming step is overlapped with the first sheet in the first overlapping step. In the turning step, the sleeve member is turned over so that the surface of the sleeve member disposed outside in the first forming step is disposed inside.

In the method for manufacturing a garment according to the ninth aspect, the joining portion of the third sheet and the fourth sheet of the sleeve member can be disposed inside the sleeve member, so that the joining portion of the sleeve member can be prevented from protruding outward to interfere with the work of the wearer of the garment. In the method for manufacturing a garment according to the ninth aspect, the third sheet and the fourth sheet of the sleeve member can be arranged in the sleeve member at the joint portion, so that the manufactured garment has a good appearance.
