[0001] METHOD FOR KNITTING KNITTED FABRIC [0002]

The present invention is characterized in that, when the knitting of a knitted fabric is resumed by stopping the yarn feeding member in the middle in the knitting width direction of the knitting fabric and moving the yarn feeding member again, (stitch) of the knitted fabric can be prevented from becoming smaller than the knitting fabric originally.

In the case of knitting a tubular knitted fabric using a weft knitting machine, transition from knitting in one (one) needle bed to knitting in the other (needle bed in the other) There is a problem that the end stitches of one needle bed are smaller than the other stitches. The reason why the end stitch becomes smaller is that the moving direction of the yarn feeding member is changed after the yarn feeding member is stopped for a moment when the traveling direction of the yarn feeding member is changed after knitting the end stitch and the tension applied to the end yarn is changed It is thought that it is because it becomes. As a means for solving such a problem, for example, a knitting method described in Patent Document 1 is known.

The knitting method of Patent Document 1 is a knitting method in which the end stitch of one of the needle beds is suppressed by using a cam system mounted on a carriage that reciprocates in the longitudinal direction of the needle bed. The cam system is a member having a function of acting on the knitting needle so as to advance the knitting needle of the needle bed toward the needle bed gap or to withdraw the knitting needle in the direction opposite to the advancing direction. Patent Document 1 discloses a knitting machine in which knitting is performed on a needle bed of the other needle bed using a cam system corresponding to one of the needle beds in a cam system corresponding to the other needle bed, Thereby preventing the end stitches of one of the needle beds from becoming small by preventing the advance of the needle bed or by inserting the needle into the retracting direction.

Here, the change in tension acting on the stitch is not caused only in the stitch in the knitting width direction end portion, but also in the stitch in the middle in the knitting width direction. As an example in which the tension acting on the stitch in the middle portion in the knitting width direction is changed, for example, when the yarn feeding member is temporarily retracted from the knitting of twisted stitch or intarsia knitting described in Patent Document 2 And the like.

In Patent Document 2, when knitting a tubular knitted fabric such as gloves and socks, a plurality of torsion stitches arranged in parallel in the knitting width direction are knitted, and these twist stitches are turned and inserted (see paragraph 0022 of Patent Document 2) Reference). The twist stitch is a stitch that is in a twisted state in advance and moves the yarn feeding member in one direction (one direction). When the yarn feeding member once passed through the knitting needle is moved in the opposite direction, the knitting yarn is fed to the knitting needle, And is knitted by moving in one direction. When the yarn feeding member is stopped and moved repeatedly in accordance with the change of direction of the yarn feeding member, the last knitted stitch (first stitch) is smaller than the knitting original when the yarn feeding member is stopped.

In addition, in the intaglio knitting using a plurality of yarn feeding members, the yarn feeding member (B), which is disturbed when knitting by the yarn feeding member (A), is returned at the middle portion in the knitting width direction. In this case, too, the tension acting on the stitch (hereinafter referred to as the first stitch) directly connected to the knitting yarn extending from the yarn feeding member B largely changes, so that the first stitch becomes smaller than the original stitch.

: Japanese Patent No. 4944015 : Japanese Patent Application Laid-Open No. 2006-111995

The knitting method of Patent Document 1 is a technique that can be applied to the end stitches in the knitting width direction in the knitting of the tubular knitted fabric. Therefore, it is not a technique that can be applied when knitting is temporarily stopped in the knitting widthwise direction in the knitting of the torsion stitch or the knitting of the knitting yarn in Patent Document 2.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a knitting yarn in which the yarn feeding member is stopped in the middle in the knitting width direction of the knitting fabric and the yarn feeding member is moved again, Which is capable of restraining a first stitch knitted at the last time from becoming smaller than a knitting stitch at the time of knitting.

A method of knitting a knitted fabric according to the present invention comprises a needle bed and a needle bed facing one another and a yarn feeding member feeding a knitting yarn to a needle bed gap formed between one needle bed and the other needle bed The first yarn is stitched on one of the needle beds by using the yarn feeding member, and then the yarn feeding member is stopped and the yarn feeding member is moved again so that the knitting width of the first stitch In a knitting method for knitting a knitting fabric that knits a second stitch adjacent to the first stitch in the direction of the first stitch.

[Process alpha] ... The first stitch directly connected to the knitting yarn fed from the yarn feeding member is transferred from the knitting needle of one needle bed to the needle of the other needle bed.

[Process beta] ... The yarn feeding member is moved to knit the second stitch and the knitting needle to which the first stitch on the other needle bed is engaged is inhibited from advancing toward the needle bed gap.

[Process γ] ... The first stitch is returned to the knitting needle that has been engaged before being transferred in the step a.

Further, when the moving direction of the yarn feeding member is changed, the yarn feeding member is stopped for a very short time. Therefore, changing the moving direction of the yarn feeding member includes "stopping the yarn feeding member and moving the yarn feeding member again".

Here, the state in which the knitting needle in the step? Is prevented from advancing toward the needle bed gap can be achieved by any one of the following. For example, a cam system mounted on a carriage can be used to inhibit advance of the knitting needle.

[1] Fix the knitting needle so that the knitting needle does not advance toward the needle bed gap.

[2] While the knitting needle is restricted from advancing toward the needle bed gap, it is not limited that the knitting needle exits from the side opposite to the needle bed gap.

[3] Draw the needle on the opposite side of the needle bed gap.

As a method of knitting a knitted fabric of the present invention, in the case of knitting a tubular knitted fabric without forming coprecipitation between adjacent stitches, the stitches to be bonded to the other needle bed are moved before the step & And a step of forming a coprecipitate < RTI ID = 0.0 > a '. ≪ / RTI > One of the knitting needles of the needle bed may be used for the movement of the stitch. For example, in the case of using a four-bed flat knitting machine having one needle bed arranged vertically and two needle beds arranged vertically and two needle beds arranged vertically, two of the two needle beds Is used as the needle bed. Further, in the case of a weft knitting machine having a holding function for once holding the stitches, the stitches of the other needle bed may be held on the knitting needles of one of the needle beds in order to form a coin needle on the other needle bed For example, Japanese Patent Application Laid-Open No. 11-43849, etc.).

As a method of knitting a knitted fabric of the present invention, there is a form in which the second stitch is a torsion stitch. In order to make the second stitch into a torsion stitch, the moving direction of the yarn feeding member when knitting the second stitch is made to be opposite to the moving direction of the yarn feeding member when the first stitch is knitted, as described later in the embodiment. Of course, the method of knitting a knitted fabric of the present invention also includes a mode in which the second stitch is not made into a torsion stitch. In the case where the second stitch is not a torsion stitch, the moving direction of the yarn feeding member when knitting the second stitch may be the same as the moving direction of the yarn feeding member when the first stitch is knitted.

According to the knitting method of the knitted fabric of the present invention, the cam system acting on the knitting needle of the other needle bed which joins the first stitch by moving the first stitch to the other needle bed before knitting the second stitch, The cam systems acting on the knitting needles of one of the needle beds knitting the stitches can be made different from each other. The timing at which both the cam systems act on the knitting needle can be matched by making the cam system acting on the knitting needle for engaging the first stitch and the cam system acting on the knitting needle for knitting the second stitch different from each other, The second stitch can be knitted while restraining the knitting needle from advancing toward the needle bed gap. Therefore, according to the knitting method of the knitted fabric of the present invention, even if the knitting of the knitted fabric is resumed by stopping the yarn feeding member in the middle of the knitting width direction of the knitting fabric and moving the yarn feeding member again, It is possible to prevent the first stitch from becoming smaller than the knitting original.

According to the method of knitting a knitted fabric of the present invention having the process? ', Even when the tubular knitted fabric is knitted without forming coprecipitates between adjacent stitches, it is possible to suppress the first stitches from becoming smaller than the knitting original.

According to the method of knitting a knitted fabric of the present invention, even when the second stitch is a twist stitch, that is, when the yarn feeding member is moved in the direction toward the first stitch to knit the second stitch, the first stitch is smaller Can be suppressed. This is because the cam system acting on the knitting needle for engaging the first stitch and the cam system acting on the knitting needle for knitting the second stitch are different from each other, so that the timing at which both cam systems act on the knitting needle can be matched.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a knitting method of a knitting fabric according to the present invention will be described with reference to the drawings. The weft knitting machine used in the embodiment includes a lower front needle bed (hereinafter, FD) extending in the left-right direction and facing each other in the front-rear direction, and a lower front needle bed a lower front needle bed (hereinafter, referred to as BD), and an upper front needle bed (hereinafter referred to as FU) provided above these FD and BD and having a plurality of knitting needles arranged at the same pitches as FD and BD, And an upper back needle bed (hereinafter, referred to as BU). In this flat knitting machine, a needle bed gap is formed between the FD (FU) and the BD (BU), and a yarn feeding member feeds the knitting yarn to the needle bed gap. Thereby knitting a knitted fabric. Also, in this flat knitting machine, stitch transfer can be performed between the FD (FU) and the BD (BU), and BD and BU provided in the flat knitting machine can be racked left and right.

In this embodiment, in the case of knitting a tubular knitted fabric 10 having the front knitted fabric 10F and the rear knitted fabric 10B shown in Fig. 1, in the front knitted fabric 10F, A twisted stitch is knitted in a specific region (specific region) 10R on the left side (left end side), and the twisted stitch is turned by turning it toward the rear knitted fabric 10B. The tubular knitted fabric 10 may be knitted by forming an empty needle between adjacent stitches. In the present embodiment, knitting is performed between adjoining stitches without forming coprecipitation.

The order of knitting the specific region 10R will be described with reference to Fig. In Fig. 2, " S + number " in the left column indicates the number of the knitting process, and in the right column, the knitting condition of stitches in each knitting process is shown. The black dot in the black circle indicates a knitting needle provided in the needle bed, a circle indicates a stitch, a symbol indicates a stitch newly knitted in each knitting process, and an arrow indicates a transfer direction of the stitch. Upper case alphabets A to G of URAN indicate the needle positions of FD and FU, and lower case alphabets a to g denote needle positions of BD and BU. In addition, in the right column, the part actually knitted in each knitting step is indicated by a bold line.

In S1, the yarn feeding member 9 is moved in the left direction of the paper surface to knit a new stitch subsequent to the stitches to be bonded to the knitting needles G, F, E of the FD, And stops at the position on the left side of the knitting needle (D). The stitches (first stitches 1) to be engaged with the knitting needles E of the FD are stitches that are finally knitted when the yarn feeding member 9 is stopped and are directly connected to the yarn feeding member 9. [ By this S1, the front knitted fabric 10F is knitted up to the front of the specific region 10R. The reason why the stop position of the yarn feeding member 9 is set to the left side of the knitting needle D in S1 is that knitting stitches 2 are knitted on the knitting needle D of the FD in a later step.

The stitches 3 of the rear knitted fabric 10B joined to the knitting needle d of the BD are moved to the knitting needles F of the FU after the BD and BU are racked two pitches in the rightward direction Process α '). This S2 is for forming a coin to move the first stitch 1 in the next step S3. For this reason, in the case of knitting a knitted fabric by forming coprecipitation between adjacent stitches, this S2 is not necessary. Also, both BD and BU are racked because BD and BU are integrally racked in the present structure of the flat knitting machine.

In step S3, the first stitch 1 coupled to the knitting needle E of the FD is moved to the knitting needle d of the co-ordinated state of the BD after one pitch of BD and BU is lapped in the left direction ). The knitting needle (d) of the BD is the coin needle formed by S2.

In S4, first, BD and BU are racked one pitch leftward. The yarn feeding member 9 is moved in the rightward direction to knit a new stitch (second stitch 2) on the stitch to be engaged with the knitting needle D of the FD and the BD (first stitch) The knitting needle d of the first stitch 1 is inhibited from advancing toward the needle bed gap so that the knitting of the first stitch 1 is prevented from becoming smaller than the original stitch (step? Of the present invention). The movement of the knitting needle d in the advancing direction can be suppressed by, for example, a cam system of the carriage advancing and retracting the knitting needle of the BD as in Patent Document 1. [

Here, when the cam system is used to inhibit the movement of the knitting needle (d) in the advancing direction, the cam system is actuated on the knitting needle (d) according to the knitting timing of the second stitch (2). Specifically, the position of the knitting needle (d) in the left-right direction is adjusted so that the cam system acts on the knitting needle (d) at least until the knitting of the second stitches (2) is completed. The knitting needle d to which the first stitch 1 is engaged is disposed at a position opposite to the knitting needle D of the FD to which the second stitch 2 is engaged as shown in Fig. Of course, if the knitting needles d of the BD and the knitting needles D of the FD are in the range of allowing the cam system to act on the knitting needle d of the BD until the knitting of the second stitches 2 is finished, It may be out of order.

In S5, the yarn feeding member 9 is moved to the left to stop the yarn feeding member 9 to the left of the knitting needles C of the FD. At the end of this step S5, the second stitches 2 joined to the knitting needle D of the FD become torsion stitches. If the second stitches 2 are not made to be twist stitches, the yarn feeding member is returned to move the yarn feeding member in the right direction instead of performing the above-described S4. Instead of performing the step S5, the yarn feeding member 9 is moved in the leftward direction to knit the stitches (second stitches 2) on the knitting needles D of the FD, and the first stitches 1 are engaged The knitting needle d of the BD is inhibited from advancing toward the needle bed gap.

In step S6, BD and BU are racked one pitch in the rightward direction, and then the first stitch 1 attached to the knitting needle d of the BD is returned to the knitting needle E of the FD in step S3 γ).

In step S7, BD and BU are racked one pitch in the rightward direction, and the stitches 3, which were engaged with the knitting needles F of the FU in S2, are returned to the knitting needles d of the BD.

After S7, knitting stitches in the knitting needles C, B, A of the FD need to be knitted in the same manner as S2 to S7. Specifically, in the case of knitting a torsion stitch in the knitting needles C of the FD, the second stitches 2, which are twist stitches knitted at the knitting needles D of the FD in S5, are defined as the first stitches 1 , And S2 to S7. By repeating the same knitting as S2 to S7 in this manner, it is possible to suppress the torsion stitches of the knitting needles D, C, and B of the FD from being smaller than the original knitting. Further, in order to suppress the torsion stitch of the knitting needle A from becoming small when knitting the rear knitted fabric 10B following the knitting of the twist stitch in the knitting needle A of the FD, using the technique of Patent Document 1 do.

Here, in repeating the same knitting as that of S2 to S7, the n-th S6 may be regarded as the (n + 1) th S2 and S7 may be omitted (n is a natural number). In other words, it is regarded that the step? Of the present invention for the n-th time and the step? 'Of the present invention for the (n + 1) th time are concurrently performed, and S7 may be omitted.

According to the knitting method described above, it is possible to suppress the torsion stitch of the specific region 10R and the stitch (first stitch) of the knitting needle E of the FD adjacent to the right side of the specific region 10R from becoming smaller than the original knitting . Therefore, the loop quality in the vicinity of the torsion stitch can be made substantially the same as the other portions, and the smoothness of the knitted fabric can be improved as compared with the conventional art.

In the above-described embodiment, the method of knitting a knitted fabric of the present invention is applied to a tubular knitted fabric. However, in a method of knitting a knitted fabric of the present invention into a single-layer knitted fabric to be bonded to one of the front and rear needle beds May be applied. The knitting method of the knitted fabric of the present invention may be applied when the yarn feeding member is temporarily stopped and then restarted in the knitting of the intaglio. By doing so, the formation of the second stitch and the knitting needle bed It is possible to inhibit the advance to the gap side.
