Abstract

A knitting method of an intersia pattern fabric and a weft knitting machine in which the condition of yarn catch can be improved. As shown at (a), when a knitting yarn (5) is kept hooked from the knitting needle (3a) of high tuck on the starting side of a section to the knitting needle (3d) of high tuck on the ending side, inclination angle of the knitting yarn (5) becomes ϑ. Drawing-in of the knitting needle (3d) on the ending side is preceded. As a result of preceded drawing-in, inclination angle of the knitting yarn (5) decreases to φ and the timing at which the knitting yarn (5) is hooked to the hook (6b) can be delayed. Because of this timing lag, yarn catch at the knitting needle (3b) begins after knock over is started at the knitting needle (3a) on the starting side. Knock over started at the knitting needle (3a) can decrease a level difference of the knitting yarn (5) at an adjoining knitting needle (3b) and the condition of yarn catch can be improved.

Method for knitting intarsia pattern knitted fabric and flat knitting machine

Technical field

[0001] The present invention relates to a knitting method and a flat knitting machine for an intarsia pattern knitted fabric in a flat knitting machine capable of simultaneously supplying knitting yarn that can be warp yarns in a plurality of sections.

Background art

Conventionally, a flat knitting machine for knitting a weft knitted fabric is basically a flat knitting machine that can supply a knitting yarn that can be used as a warp for knitting a knitted fabric similar to a warp knitted fabric. A knitting yarn supply device for a knitting machine is used (for example, see Patent Document 1). This knitting yarn supply device is equipped with a lace bar which is equipped with a plurality of yarn supply pipes and can simultaneously supply knitting yarn in a plurality of sections, and performs a wrapping operation which reciprocates in the longitudinal direction of the needle bed of the lace bar. With a swing motion that swings to the front and back of the needle bed, a structure similar to a warp knitting structure in which the knitting yarns forming the stitches continue in the wale direction can be knitted. An intarsia pattern knitted fabric can be knitted by combining the wrapping operation of the race bar and the swing operation (see, for example, Patent Document 2).

FIG. 6 shows a state in which the knitting yarn 5 is passed from the yarn supply pipe 4 attached to the lace bar to the plurality of knitting needles 3 advanced from the needle bed 2 to the mouth 1. As shown in FIG. 6 (a), the yarn supplying pipe 4 passes the knitting yarn 5 for each section by the swing operation, wrapping operation and swing operation of the race bar. Here, one section is formed by four knitting needles 3 a, 3 b, 3 c and 3 d. At the start end of the section, the yarn supply pipe 4 swings in a swing motion from the back side to the front side on the left side of the knitting needle 3a, and the knitting yarn 5 is pulled from the old loop of the knitted fabric that is locked to the back side of the needle bed 2. Pull out to the front side of needle bed 2. The yarn feed pipe 4 is moved laterally by the lapping operation from the knitting needle 3a on the start end side to the knitting needle 3d on the end side, and the yarn feed pipe 4 is connected to each knitting needle 3a, 3b, 3c, 3d belonging to this section. Feed knitting yarn 5 from the tip of. On the end side of the section, on the right side of the knitting needle 3d, the yarn supply pipe 4 swings by swinging from the front side to the back side of the needle bed 2, and the knitting yarn 5 is pulled out. Needle bed 2 is inclined upward with respect to Tooth 1 so that Tooth 1 side rises . A yarn feeder equipped with a lace bar is provided above the needle bed facing the needle bed 2 with the tooth lip 1 in between, and the tip of the yarn feed pipe 4 is positioned on the front side of the extension line of the needle bed 2 The knitting yarn 5 is pulled toward the tip of the knitting needle 3 and hooked on the hook 6 at the end of each section. Therefore, the knitting yarn 5 to be stretched is inclined at an angle Θ (0 ° <6 »<90 °).

[0004] As described in paragraphs 0 0 4 6 of Patent Document 2, in the tuck knitting used to connect the intarsia boundary between warps, the old loop side that is knocked over by the knitting operation of the knitting needle 3 is used. In addition, a high tack for tacking the knitting yarn 5 can be selected. In the following, when the same kind of knitting needles 3 a, 3 b, 3 c, 3 d, etc. are indicated generically, only numbers such as “3” are described, and letters following the numbers such as “a” are omitted. To do. With high tack, there is no retraction by hook 6 and a knitted fabric with a tight clog is obtained. A knitting needle 3 shown in FIG. 6 is a composite needle having a needle body 7 having a hook 6 at its tip and a slider 8 for opening and closing the hook 6. The slider 8 is composed of two plates, and is of a type that can be transferred when the hook 6 of the needle body 7 is moved to the side of the mouth 1 from the position where the hook 6 is closed. When a compound needle is used as the knitting needle 3 and the knitting yarn 5 is passed with the start and end sides of the section in a high tack state, the knitting yarn 5 on the start end side is fed onto the slider 8 as shown in (b). Then, the knitting yarn 5 on the end side is fed into the hook 6. The knitting needles 3b and 3c in the middle of the section capture the knitting yarn 5 to be caught in the hook 6 to form a stitch, so that the plating knitting operation is selected as in the case of using the splicing yarn. Is done.

FIG. 7 and FIG. 8 simply show a partial configuration of a warp cam lock 10 that drives the knitting needle 3 shown in FIG. 6 for knitting operation. The warp cam lock 10 corresponds to one of the three systems mounted in the carriage that reciprocates in the longitudinal direction of the needle bed 2, as in FIG. 1 of Patent Document 2. A weft cam lock is provided on the left side of the figure, and a warp cam lock is further provided. The warp cam lock 10 shown in the figure and the left-hand warp cam lock (not shown) act to move the selected knitting needle 3 forward to the tooth mouth 1 when the carriage is moving left and right. I do. Fig. 6 shows the knitting needle 3 that stays in the mouth 1 The lace bar equipped with the yarn feeder 4 performs swinging and rubbing operations, and passes the knitting yarn 5. The warp cam lock 10 draws the knitting needle 3 around which the knitting yarn 5 is stretched by the stitch cam 18 in order from the start end side to the end side when the carriage moves rightward to form a stitch. Similarly, the left warp cam lock (not shown) forms a stitch when the carriage moves to the left.

[0006] The warp cam lock 10 includes a needle body cam lock 1 1 for guiding a bag for driving the needle body 7, a slider cam lock 1 2 for guiding a bat for driving the slider 8, and an A presser 1 3 , H presser 14 and B presser 15 are included. Each knitting needle 3 is selected so that the select jack is in the A position, H position or B position by the action of the needle selection mechanism provided between the weft cam lock on the left side of the figure. The A presser 13 is a movable presser capable of switching between operation and non-operation, and is provided in a path through which a bar protruding from a selector jack whose A position is selected passes. H presser 14 has two movable H pressers 14 a and 14 b that can be switched between action and non-action individually, and the path through which the butt of the select jack with the H position selected passes. Provided. The B presser 15 is a fixed presser that always operates, and is provided in the path through which the back of the select jack with the B position selected passes.

[0007] The needle main body cam lock 1 1 includes a needle raising cam 1 6 having inclined cam surfaces 1 6 a and 16 b for guiding the needle body 7 to advance into the tooth opening 1, and a needle raising cam 1 A guard cam 1 7 provided above 6, a stitch cam 18 having an inclined cam surface that guides the needle body 7 to be pulled from the tooth opening 1 when the carriage is on the right side, and a selector jack lowering cam 1 9 including.

FIG. 7 shows a path through which each bag is guided at the time of high tack set for the knitting needle 3 on the start end side and the end end side of each section in FIG. The selector jack is selected as the H position. When the carriage moves to the left, the first half of the H presser 14a is inactive and the second half of the presser 14b is set to active. The left-hand path 2 2 a of the bag 卜 2 1 that drives the needle body 7 rises toward the mouth 1 side along the rising cam surface 1 6 a. Reach the needle raising cam 1 from the shoulder position of the 6

Since 14 a is inactive, the needle advancing further toward the mouth 1 side along the rising cam surface 16 b of the needle raising cam 16. The guard cam 17 is provided with a two-step descending force surface 17a and 17b. The lower cam surface 1 7a on the left side is jumped because it corresponds to the position where the second half H presser 14b is applied, and the bag 2 1 moves along the lower cam surface 1 7b on the right side. Returned to the shoulder position, descended to the lower end of the descending cam surface 1 7 b and then pulled out almost horizontally to the right in the figure. The left-hand path 2 4 a of the bat 2 3 that drives the slider 8 is the inactive action of the H-pressor 1 4 a in the first half, and the needle body 7 moves along the lifting surface 1 6 b of the needle raising cam 1 6 As you move into the mouth 1 you will move into the mouth 1 side. By the action of the second half H presser 14 b, / 2 2 3 jumps the descending cam surface 1 2 a of the slider cam lock 1 2, and the left-hand path 2 2 a of the needle body 7 is the guard force m 1 7 Even if it moves backward from the tooth opening 1 along the descending cam surface 1 7 b, it keeps the advanced position and moves to the right in the figure.

[0009] When the carriage moves to the right, both H pressers 14a and 14b are set to work. The right-hand path 2 2 b of the needle 2 7 2 of the needle body 7 is almost horizontal, the position of the shoulder of the needle raising cam 1 6 is maintained, and the inclined cam surface of the stitch cam 1 8 is reached. The needle body 7 is pulled from the mouth 1 to the needle bed 2 along The right-hand path 2 4 b of the bat 2 3 of the slider 8 is substantially horizontal up to the descending cam surface 1 2 b provided on the left side of the slider force mulock 1 2, and along the descending cam surface 1 2 b. Pull the slider 8 from the mouth 1 into the needle bed 2.

FIG. 8 shows a path through which each butt is guided during plating set for the intermediate knitting needle 3 excluding the start end side and the end end side of each section in FIG. Select 卜 Jack is selected to the A position, and A Presser 13 is set to inactive when the carriage goes to the left. As a result, the left-hand path 2 6 a of the bat 25 that drives the needle body 7 extends from the shoulder position of the needle raising cam 1 6 and further along the rising cam surface 1 6 b of the needle raising cam 1 6. Advance to the first side of the mouth. The bat 2 5 is a needle along the descending cam surface 1 7 a on the left side of the guard cam 1 7 Raising cam 1 Returned to the shoulder position of 6 and descends to the lower end of one descending cam surface a. The left-hand path 2 8 a of the battery 2 7 that drives the slider 8 is indicated by the needle body 7 as the rising cam surface of the needle raising cam 1 6

1 Advancing to the side of tooth 1 as it advances to tooth 1 along b. Batch

2 7 moves backward from the tooth opening 1 along the descending cam surface 1 2 a of the slider cam lock 12 2, and keeps the position of the lower end of the descending cam surface 1 2 a, and then comes out to the right in the figure. The select jack lowering force 19 provided on the right side of the needle raising cam 16 acts so that the select jack selected at the A position is retracted to the H position and then pulled out to the right.

[0011] When the carriage is on the right side, the selector 卜 jack selected for the A position on the left side returns to the H position by the action of the select jack lowering cam 1 9 and both are set to work. H Presser 1 Passes 4 a and 1 4 b. If the selector jack lowering cam 1 9 is not provided, the selector jack keeps the A position when the carriage moves to the left and moves to the right and returns to the A position when the carriage moves to the right. In this case as well, if the A presser 13 is set to act, the path of the needle body 7's bag 25 becomes the same as the right-hand time path 26b when returning in the H position. The right-hand path 2 6 b of the butt 2 5 of the needle body 7 reaches the inclination force surface of the stitch cam 1 8 while maintaining the shoulder position of the needle raising cam 1 6 almost along the inclination cam surface. The needle body 7 is pulled into the needle bed 2 from the mouth 1. That is, it is retracted in the same manner as the right-hand path 2 2 b of the needle body 7 shown in FIG. The right-hand path 2 8 b of the bat 2 7 of the slider 8 keeps the position left on the right side of the figure when it is on the left-hand side, and reaches almost the descending cam surface 1 2 b provided on the left side of the slider cam lock 1 2. The slider 8 is horizontal, and the slider 8 is pulled from the tooth opening 1 to the needle bed 2 along the descending cam surface 1 2 b.

Problems to be solved by the invention

[0013] As shown in Fig. 10, in the knitting needle 3b adjacent to the high-tack knitting needle 3a on the start side of the section, the knitting yarn 3 hung on the slider 8a is hooked with the knitting needle 3a. 6 Must be pulled into b. If the distance between the high-tack knitting needle 3a on the start side of the section and the high-tack knitting needle 3d on the end side is relatively small, the inclination angle Θ of the knitting yarn 5 to be spanned as shown in Fig. 6 (a) is It is necessary to catch the knitting yarn 5 at a relatively early timing in the hook 6 b of the knitting needle 3 b. As shown in Fig. 10, in the case of knitting yarn 5 that is stretched from the slider 8a of the knitting needle 3a on the start side of the high tack to the hook of the knitting needle on the end side, the starting end side is in the hook or on the hook in normal knitting. The difference in height is larger than when it is passed between the slider and the slider. In particular, when the section is short, the knitting needle 3b adjacent to the high-tack knitting needle 3a on the starting end side has a tip at the end of the hook 6b when the knitting yarn 5 shown in the section 5b is caught in the hook 6b. It may happen that the knitting yarn 5 is broken or the knitting yarn 5 cannot be captured. Depending on the conditions, it may be difficult to use the plurality of knitting needles adjacent to the high-tack knitting needle 3a on the start end side.

[0014] An object of the present invention is to provide a knitting method and a flat knitting machine for an intarsia pattern knitted fabric that can improve the conditions of yarn wetting.

Means for solving the problem [0015] According to the present invention, a pair of needle beds each having a compound needle as a knitting needle face each other at the mouth, and the knitting needle that advances from one needle bed to the mouth is performed by a swinging operation and a wrapping operation of the race bar. With a flat knitting machine that can simultaneously feed knitting yarn that can be warped from the start side to the end side in each section of multiple sections, select the knitting needles at both ends of each section to a high tack state, and start In a method of knitting an intarsia pattern knitted fabric while performing high tack connection to the knitting needle at the end of an adjacent section at the side boundary,

An intarsia pattern characterized in that a high-tack knitting needle on the end side of each section is drawn from the tooth opening to the needle bed side in advance of the knitting needle adjacent to the knitting needle that performs high-tack connection at least on the start side This is a knitting method of the knitted fabric.

[0016] Further, in the present invention, the flat knitting machine includes a cam mechanism that guides and drives the needle body and the slider of the composite needle according to a needle selection state, respectively.

The intermediate knitting needles excluding the start and end of each section are selected so that the high tack state and the needle body path are the same and the slider path is different when introduced into the cam mechanism,

The cam mechanism is branched in such a way that the path of the needle body differs depending on the slider path, and the needle body of the knitting needle selected in the high tack state is drawn in from the tooth opening in advance. And

[0017] Further, in the present invention, the compound needle is accommodated in a needle groove provided in a needle bed so that the needle body is on the bottom side and the slider is on the top side,

The cam mechanism drives the needle main body and the slider with a cam groove in the butt protruding from the needle groove,

A path for guiding the needle body bag is provided with a branch portion that guides the bag protruding from the needle groove to the path that the needle body retracts from the tooth opening.

In the path for guiding the slider bag of the intermediate knitting needle, the slider butt is pressed in correspondence with the position of the branch portion of the path for guiding the needle body bag, and the needle body bat is pushed by the branch portion. It is characterized by not branching to the route of drawing in from the mouth.

[0018] Further, the present invention provides, as a knitting needle, a needle body provided with a hook at the tip of the mouth side, A pair of needle beds provided with a compound needle having a slider that is displaced relative to the needle body to open and close the hook are opposed to each other at the mouth, and one of the knitting yarns that can become warp yarns by the swing operation and lapping operation of the race bar. In a flat knitting machine capable of knitting an intarsia pattern that is connected to the knitting needles that have advanced from the needle bed to the tooth opening and connected to the tack at the boundary,

A needle selection mechanism that selects the knitting needle that becomes the boundary of the section in a high tack state, and selects the needle in the middle of the section in a state different from the high tack;

A slider guide mechanism that guides the sliders of the knitting needles in a high tack state and a state different from the high tack state to different paths,

Guide the needle body of the knitting needle in a high tack state and a state different from the high tack to the same route halfway, and use only the needle body in the high tack state from the middle using the difference in the route in the slider guide mechanism. A flat knitting machine characterized by including a needle main body guide mechanism that guides a branching path from a tooth opening to a path to be drawn in advance.

[0019] According to the present invention, the knitting needle on the end side of each section of the intarsia pattern is drawn from the tooth opening to the needle bed side prior to the knitting needle adjacent to the knitting needle that performs high-tack connection at least on the start end side. The inclination angle of the knitting yarn spanned from the start end side to the end end side can be reduced. Since the knitting needle adjacent to the knitting needle performing high tack connection on the start end side can be inclined with the same knitting yarn as the case where the interval from the start end side to the end side is large, the timing of the thread digging is delayed. Can be made. When the high-tack knitting yarn is passed over the slider on the knitting needle on the start end side, the difference in height of the knitting yarn to be hung is large. When the knitting yarn is knocked over, the difference in height is small, and the yarn weaving height at the adjacent knitting needle is lowered, so that the yarn wetting can be improved.

[0020] Further, according to the present invention, the knitting needles at the start and end of the section and the intermediate knitting needle are branched by the cam mechanism so that the path of the needle body is different depending on the difference in the path of the slider. The needle body of the knitting needle selected in the high-tack state Can be pulled in. Since the difference in the slider path is used, the branch of the needle body path can be realized without the addition of a new selection mechanism.

[0021] According to the present invention, the needle body of the high-tack knitting needle is switched because the branch of the needle main body bat is switched by pressing the slider batter in the path guiding the slider batter. Can be achieved without the need for a movable switching mechanism.

[0022] Further, according to the present invention, the high-tack knitting needle on the end side of each section is drawn from the tooth opening to the needle bed side ahead of the knitting needle adjacent to the knitting needle performing high-tack connection on the start side at least. Therefore, it is possible to delay the timing of thread weaving with the knitting needle adjacent to the starting end side. While the timing of yarn weaving is delayed, the knitting yarn is knocked over by pulling in the knitting needle on the start side, and the yarn weaving height at the adjacent knitting needle is lowered, so that weaving can be improved.

BEST MODE FOR CARRYING OUT THE INVENTION

1 to 5, an embodiment of the present invention will be described. The parts corresponding to those described with reference to FIGS. 6 to 10 are denoted by the same reference numerals, and overlapped. The explanation to be performed may be omitted. As an example of an intarsia pattern, one section is knitted with four knitting needles 3a, 3b, 3c, 3d. The present invention can improve the yarn biting.

FIG. 1 shows a basic idea about a method of knitting an intarsia pattern knitted fabric as one embodiment of the present invention. That is, as shown in (a), when the knitting yarn 5 is stretched from the high-tack knitting needle 3a on the start side of the section to the high-tack knitting needle 3d on the end side as shown by a one-dot chain line, While the inclination angle of the knitting yarn 5 is 6 », the drawing-in of the knitting needle 3d on the end side is performed in advance. As a result of the preceding pull-in, the inclination angle of the knitting yarn 5 is reduced to 0 as indicated by the two-dot chain line. Yarn biting at the knitting needle 3b adjacent to the start end side is directed to the knitting yarn 5 at an inclination angle ø, so that the timing at which the knitting yarn 5 is applied to the hook 6b can be delayed. As will be described later with reference to FIGS. 4 and 5, before the drawing of the intermediate plating knitting needles 3b and 3c starts, the drawing of the high-tack knitting needles 3a and 3d on both sides of the section starts. . As a result, as shown in FIG. 1 (b), the knitting yarn 5 hanged from the slider 8 a of the knitting needle 3 a on the start side to the hook 6 d of the knitting needle 3 d on the end side is also retracted from the mouth 1. However, when the hook 6 b of the knitting needle 3 b is pulled, the timing for capturing the knitting yarn 5 in the hook 6 b is also delayed. [0027] FIG. 2 shows the knitting needles 3a, 3 at the timing at which the knitting needle 3b adjacent to the knitting needle 3a adjacent to the starting end side is used when the cam shown in FIGS. 4 and 5 is used. The states of b, 3c3d and knitting yarn 5 are shown. As shown in FIG. 2 (a), prior to the thread biting with the knitting needle 3 b, the knitting needle 3 a on the start side starts knocking over the knitting yarn 5 hung on the slider 8 a as a high tack. . As a result, as shown as a cross section 5a in FIG. 2 (b), the knitting yarn 5 applied to the knitting needle 3a is in the middle of being detached from the slider 8a along the outer periphery of the hook 6a. The height difference between the cross section 5a of the knitting yarn 5 on the start end side and the cross section 5d of the knitting yarn 5 in the hook 6d on the end side is also reduced, and the hook 6b only needs to be captured at the position of the cross section 5b. Reliable thread bite is possible.

FIG. 3 shows the configuration of the main part of the knitting needle 3. Knitting needle 3 consists of needle body 7 and slider

8 is a separate body, and the hook 6 at the tip of the needle body 7 is opened and closed by the relative movement of the slider 8 with respect to the needle body 7. The needle body 7 bats 2 1 and 2 5 for driving the needle body 7 and the bats 2 3 and 2 7 for driving the slider 8 are connected to the tails of the needle body 7 and the slider 8 mentioned in the explanation in FIGS. The needle jack 3 1 and the slider jack 3 2 are provided respectively. A bifurcated portion 3 1 a is provided in the vicinity of the needles 2 1 and 25 of the needle jack 3 1 and accommodates the tail portion of the slider jack 3 2. When the tail end of the slider jack 32 contacts the inner surface of the bifurcated portion 3 1 a of the needle jack 31, the slider 8 is prevented from moving backward relative to the needle body 7. That is, with the tail end of the slider jack 3 2 in contact with the inner surface of the bifurcated portion 3 1 a, the hook 6 opens to the maximum. In this state, if the needle body 7 advances to the tooth opening 1, the slider 8 also advances to the tooth opening 1. If the butt 2 3 and 2 7 of the slider jack 3 2 is driven and only the slider 8 is advanced to the tooth mouth 1 side, the needle body 7 stays, so that the hook 6 can be closed at the end of the slider 8 . The slider of the compound needle described in Patent Document 2 can be moved relative to the needle body only to the position where the hook is closed. However, in the knitting needle 3 of this embodiment, the slider 8 can be further moved. . Such differences do not affect the implementation of the present invention, and the present invention is patented. The same applies to compound needles as described in Document 2.

[0029] The knitting needle 3 is accommodated in a needle groove formed in the needle bed 2, and slides and displaces in the needle groove. Needle jack 3 1 and slide jack 3 2's 2 1 2 5; 2 3 and 2 7 are affected by the cam. Butts 2 1 and 2 5; 2 3 and 2 7 protrude outside the needle groove It is time to do. In the needle groove, above the tail portion of the needle jack 31 is a select jack not shown. The select jack is inserted into the needle groove when it receives the action of the A presser 13, H presser 14, or B presser 15 described in FIGS. 9 and 10, and FIGS. 4 and 5 described later. As a result of being submerged, the needle jack 3 1 is also interlocked and submerged in the needle groove. As a result, the bats 2 1 and 2 5; 2 3 and 2 7 also do not protrude out of the needle groove.

4 and 5 show a simplified partial configuration of the warp cam lock 40 that drives the knitting needle 3 shown in FIG. 1 for knitting operation. Fig. 4 shows the left-handed path 2 2 a, 2 4 a, where the high-tack knitting needle 3 is guided by the back 2 1 that drives the needle body 7 and the back 2 3 that drives the slider 8. And right-hand routes 2 2 b and 2 4 b are also shown. FIG. 5 shows a path 2 6 a, 2 8 for the knitting needle 3 of the plating, in which the guide 2 5 for driving the needle body 7 and the guide 2 7 for driving the slider 8 are guided. A and right-hand routes 2 6 b and 2 8 b are also shown. The warp cam lock 40 is the same as the warp force mulock 10 except that the warp cam lock 10 shown in FIGS. 7 and 8 is partially modified as described later. Further, although the warp force mulock 40 mounted on the right side of the carriage is described, it goes without saying that the same applies to the warp cam lock mounted on the left side.

[0031] As shown in FIG. 4, the warp cam lock 40 has a branch cam portion 41 added to the guard cam 17 of the needle main body cam lock 11 that guides the bag 21 that drives the needle body 7. It is. The branch cam part 4 1 is a high-tack needle when the carriage moves to the right.The path 2 2 b of the right side of the bag 2 that drives the main body 7 is lowered along the cam surface 4 1 a of the branch cam part 4 1 Branch off from mouth 1. Bag after branch 右 2 1's right-hand path 2 2 b passes through a position that is further retracted from the mouth 1 while passing through the shoulder of the needle-raising cam 16 at the conventional high tack shown in Fig. 7. On the left side of the branch cam section 41, there is an inclined surface 4 1 b that increases in height from the cam plate surface of the carriage. You can move over.

[0032] When the carriage moves to the right in FIG. 4, the position where the bag 21 is branched by the branch cam portion 41 and retracted from the tooth opening 1 is the knitting yarn from the yarn supply pipe 4 shown in FIG. 1 (a). Within the range where the conditions for smooth supply of 5 are satisfied. Although not shown, a thin force is placed between the knitting needles 3. When the hook 6 of the knitting needle 3 is pulled into the needle bed 2, the knitting yarn 5 first contacts the tip of the thin force, and the thin force and the hook Pull the knitting yarn 5 with 6 to form a new stitch loop, and then knock over the old loop. When the high-tack knitting needle 3d on the end side is knocked over first, the new loop force and the hook 6 are tightened with the old loop, and the supply of the knitting yarn 5 to the other knitting needles belonging to the section stops. End up. Even if knock-over does not occur, if the knitting needle 3d is pulled in and the knitting yarn 5 comes into contact with the thin force, the friction between the thin force and the knitting yarn 5 will increase, and the knitting yarn 5 will not be supplied smoothly. There is a fear. In the knitting needles 3 a, 3 b, 3 c, 3 d in each section, it is necessary to sequentially form the stitches from the knitting needle 3 a on the start end side to the knitting needle 3 d on the end side. Accordingly, it is preferable that the leading retraction of the knitting needle 3d on the end side by the branch cam portion 41 is in a range where the knock-over is not performed and the knitting yarn 5 is also in a range where the knitting yarn 5 is not in contact with the thin force.

[0033] The position of the H presser 14 4 b acting on the needle jack 31 is in time for the timing when the retracted position right-hand path 2 2 b contacts the inclined cam surface of the needle raising cam 16. Since there is no slider, the presser part 4 2 is added to the slider cam lock 1 2 to push the slider 2 3 of the slider jack 3 2 into the needle groove, that is, the front side of the page. When the back 2 3 is pushed down by the presser section 4 2 in the right-hand path 2 4 b of the back 2 3, when the back 2 3 is pushed down, the combination of the slider jack 3 2 and the needle jack 3 1 as shown in Fig. 3 3 1 is also pushed down, and the bag 2 1 sinks into the needle groove. As a result, the battery 2 1 Jump on the inclined cam surface of Ising cam 1 6 and move horizontally until it touches the inclined cam surface of stitch cam 1 8 on the left. When the carriage is on the right, keep both H pressers 14 inactive. At the left side of the carriage, the second half H presser 14 b is operated so that the bat 21 jumps on the descending cam surface 17 a of the guard cam 17.

[0034] As shown in FIG. 5, the bat 25 that drives the needle body 7 during plating is not branched, and the descending cam surface 41a of the branch cam portion 41 is jumped. For this reason, the presser section 4 3 is provided in the right-hand path 2 8 b of the bat 2 7 that drives the slider 8, and the slider jack 3 2 is submerged in the needle groove in the same manner as the presser section 4 2 described above. Then, the needle jack 3 1 is also submerged in the needle groove so that the bag 卜 2 7 jumps on the descending cam surface 4 1 a.

[0035] In the present embodiment, the difference between the right traveling paths 2 4 b and 2 8 b of the pads 23 and 2 7 that drive the slider 8 with high tack and plating is used to perform the plating. The presser part 4 3 is provided in the right-hand path 2 8 b, and only the high tack is used to branch the right-hand path 2 2 b of the bag 21 that drives the needle body 7. At the position where the presser part 4 3 is provided, the path 2 8 a on the left side of the battery 2 7 also coincides with the path 2 8 b on the right side, and the presser part 4 3 It affects 2 7 but does not affect the left-hand path 2 2 a of the battery 2 1. This is because the butt 2 1 gets over the inclined surface 4 1 b of the branch cam portion 4 1 in the left-hand route 2 2 a as described above.

[0036] The basic idea as shown in Fig. 1 is, for example, if you select plating without using the select jack lowering cam 19 in Fig. 5, the select jack will keep the A position, It can also be realized by adding a presser acting on the selector jack corresponding to the position where the branching cam part 41 is provided and jumping the descending cam surface 41a of the branching cam part 41. In addition, for example, even in a flat knitting machine in which an actuator such as a linear motor is provided on the knitting needle 3 and the knitting needle 3 is individually driven without driving the knitting needle 3 with a cam mounted on the carriage, the control changes Can be realized. Ie, book It goes without saying that changes and modifications to the present invention may be made without departing from the spirit and scope of the invention.
