Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a method of joining a knitted fabric in which knitted fabric portions to be engaged with front and back needle beds of a flatbed knitting machine are joined.

  As a method of joining the wale direction end parts of the 1st knitted fabric part and the 2nd knitted fabric part which are back and forth opposed using a flat knitting machine, the method of patent document 1 is mentioned, for example. In Patent Document 1, knitting of a new stitch in a stack in which two adjacent stitches are overlapped at the end of the first knitted fabric portion in the wale direction and knitting of two adjacent stitches at the end of the second knitted fabric portion in the wale direction The two knitted fabric portions are joined by sequentially repeating knitting of a new stitch in a stack of two stitches.

Patent No. 5619008 gazette

  The technique of Patent Document 1 is suitable for joining a first knitted fabric portion and a second knitted fabric portion of Tendon tissue. However, when at least one of the first knitted fabric portion and the second knitted fabric portion has a rib structure, the joint portion is easily bent as if it is wavy. The bending of the joint tends to be more remarkable as n and m of the rib structure of n × m become larger. For example, the photograph shown in FIG. 5A is a photograph showing a knitted fabric obtained by joining a first knitted fabric portion and a second knitted fabric portion of a 2 × 2 rib structure, and the joint portion at the upper end of the knitted fabric It turns out that it has become violently waved. This is because, while the knitted fabric portion of the rib structure is easily shrunk, the amount of contraction of the knitted fabric portion and the amount of contraction of the welded portion because the joint portion forming and fixing a new stitch is difficult to shrink. It is because there is a difference. When the knitted fabric is worn, since the joint extends as shown in FIG. 5B, bending of the joint is less noticeable, but it is easy to notice when the knitted fabric is folded. In recent years, displays may be made in the state where the knitted fabric is folded at the store, and there is a need to avoid that the bending of the joint is noticeable.

  The present invention has been made in view of the above-mentioned circumstances, and it is possible to make a joint between two knitted fabric parts flat even if at least one of the first knitted fabric part and the second knitted fabric part has a rib structure. The purpose is to provide a bonding method of

The joining method of the knitted fabric of the present invention is
Using a flatbed knitting machine having a first needle bed and a second needle bed facing each other and a yarn feeding member for feeding knitting yarn to these needle beds,
The overlapped the first adjacent knitting eyes, the first knitted fabric portion first end knitting eyes at the one end of the knitting width direction of, adjacent to the first end stitch thereof to be engaged with the first needle bed Step A of forming a first layer;
Step B of knitting a new first end stitch which continues in the wale direction of the first lap;
The overlapped the second adjacent knitting eyes, a second knitted fabric portion second end knitting eyes at the one end of the knitting width direction of, adjacent to the second end stitch to be engaged with the second needle bed Step C of forming a second layer;
Step D of knitting a new second end stitch which continues in the wale direction of the second lap;
In the bonding method of the knitted fabric in which the ends in the wale direction of the first knitted fabric portion and the second knitted fabric portion are bonded repeatedly
At least one of the first knitted fabric portion and the second knitted fabric portion is a rib structure,
In the case where the first adjacent stitch has a face, the yarn feeding member is disposed closer to the one end than the first end stitch in the step A, and the first end stitch is formed on the back side of the first adjacent stitch. To form the first double stitches, and knitting the new first end stitches to be reverse stitches in the step B,
When the first adjacent stitch is a reverse stitch, the first end is placed on the front or back side of the first adjacent stitch in a state where the yarn feeding member is disposed closer to the one end than the first end stitch in the step A A stitch is overlapped to form the first lap, and a new first end stitch which is a front stitch in the step B is knitted,
In the case where the second adjacent stitch has a face, the yarn feeding member is disposed closer to the one end than the second end stitch in the step C, and the second end stitch is formed on the back side of the second adjacent stitch. To form the second double stitches, and knitting the new second end stitches to be reverse stitches in the step D,
When the second adjacent stitch has a reverse stitch, the second end is placed on the front or back side of the second adjacent stitch in a state where the yarn feeding member is disposed closer to the one end than the second end stitch in the step C The stitches are overlapped to form the second lap, and a new second end stitch which will be the front stitch in the step D is knitted.

  Here, when the front surface is a stitch of the first knitted fabric portion (the second knitted fabric portion), the first knitted fabric side in the opposing direction of the first knitted fabric portion and the second knitted fabric portion When viewed from (the second knitted fabric part side), it is pulled from the old stitch from the second knitted fabric part side (the first knitted fabric part side) toward the first knitted fabric part side (the second knitted fabric part side) It is a stitch to be done. The back stitch is a stitch drawn out in the opposite direction to the front stitch. Further, in the present specification, “the front side of the stitch” means, when the stitch is a stitch of the first knitted fabric portion, the first knitted fabric portion in the opposing direction of the first knitted fabric portion and the second knitted fabric portion. Is the side on which the On the other hand, "the back side of the stitch" means that, when the stitch is the stitch of the first knitted fabric portion, the second knitted fabric portion in the opposing direction of the first knitted fabric portion and the second knitted fabric portion It is the side to be placed.

As one mode of the joining method of the knitted fabric of the present invention,
When the first adjacent stitch is a reverse stitch, the first end stitch is overlapped on the front side of the first adjacent stitch in the step A,
When the second adjacent stitch is a reverse stitch, the second end stitch may be overlapped on the front side of the second adjacent stitch in the step C.

As one mode of the joining method of the knitted fabric of the present invention,
The first knitted fabric portion and the second knitted fabric portion have the same rib structure, and the front mesh of the first knitted fabric portion and the second knitted fabric portion, and the first knitted fabric portion and the second knitted fabric The form which joins backs of a part can be mentioned.

  According to the joining method of the knitted fabric of the present invention, the first knitted fabric is formed by the crossover yarn that connects the new first end stitch formed in step B and the new second end stitch formed in step D. The part and the second knitted part are joined. The crossover yarn is disposed like a stitch at the joint, and the joint becomes inconspicuous. Further, in the method of joining the knitted fabric according to the present invention, depending on whether the adjacent stitch is the front stitch or the back stitch, the overlapping manner of the adjacent stitch and the end stitch is changed, and the new end stitch continuous to the lap stitch It is changing whether to make it a back eye. By doing so, according to the shape of the rib structure of the knitted fabric portion, it is possible to make a joint that follows the expansion and contraction of the rib structure, and at least one of the first and second knitted fabric portions is a rib structure. Even in this case, it is possible to make the joint between the two knitted fabric parts flat.

  The back of the rib structure becomes difficult to see from the outside when the rib structure contracts in the crosswise direction, but becomes visible from the outside when the rib structure is stretched. When the adjacent stitch is a back stitch, the appearance of the joint is better if the end stitch is overlapped on the front side of the adjacent stitch rather than the end stitch on the back of the adjacent stitch. Therefore, by overlapping the end stitches on the front side of the adjacent stitch consisting of the back stitch, the appearance of the joint can be improved even when the rib structure is stretched.

  The rib texture of the first knitted fabric portion and the second knitted fabric by joining the front stitches of the first knitted fabric portion and the second knitted fabric portion and the back stitches of the first knitted fabric portion and the second knitted fabric portion The two knitted fabric parts are connected in such a manner that the rib tissue of the part is continuous. As a result, even if the two knitted fabric parts have a rib structure, the joint between the two knitted fabric parts is not noticeable, and the appearance of the knitted fabric is good.

First Embodiment
In the first embodiment, an example in which a front body 51 and a back body 52 constituting a body 50 of a sweater (knitted fabric) 100 shown in FIG. 1 are joined at a position of a shoulder line will be described. The front body 51 and the back body 52 are formed of a rib structure, and by forming the joint portion 55 of the both 51 and 52 smoothly, the commercial value of the sweater 100 is increased and the wearing comfort is also improved. Here, the knitted fabric to be a target of forming the joint portion is not limited to clothing, and may be, for example, an accessory such as a bag, a cover of furniture, or the like.

  Hereinafter, a method of joining the knitted fabric in which the end in the wale direction of the front body 51 and the back body 52 of FIG. 1 is joined will be described based on the knitting process diagrams shown in FIGS. In FIGS. 2 and 3, the back body 52 is described as a first knitted fabric portion 1 and the front body 51 is described as a second knitted fabric portion 2. The flat knitting machine used for the method of joining knitted fabrics is a four-bed flat knitting machine having two sets of front and rear needle beds extending in the left-right direction and facing each other in the front-rear direction. The flat knitting machine may be a two-bed flat knitting machine, in which case it is preferable to carry out a needle removal knitting in which an empty needle is provided between adjacent stitches.

  The “S + number” described in the small columns in FIGS. 2 and 3 indicates the number of the knitting process, and the large column on the right of the small column shows the state of the knitting in each knitting process. The black dots in the large columns indicate the knitting needles, the inverted triangle marks indicate the yarn feeding member 9, and the upper case alphabets in the margin indicate the positions of the knitting needles. Circle marks in the large columns indicate outer stitches, diamond marks indicate back stitches, double circle marks indicate lap stitches, and filled marks indicate stitches knitted in the knitting process. Further, the left side and the right side of the drawing sheet indicated by the arrows in the margin will be referred to as one end side LS and the other end side RS in the knitting width direction, respectively.

  In S1 of FIG. 2, the stitches of the first knitted fabric portion 1 are engaged with the lower back needle bed (hereinafter referred to as BD) and the stitches of the second knitted fabric portion 2 are engaged with the lower front needle bed (hereinafter referred to as FD) The state is shown. Both knitted fabric parts 1 and 2 have a rib structure of 1 × 1 in which front and back eyes are alternately arranged in the knitting width direction, and front and back stitches of both knitted fabric parts 1 and 2 are arranged at opposing positions. ing. The subsequent knitting is performed continuously by one yarn feeding member 9. The yarn feeding member 9 may be a plating carrier having a plurality of yarn feeding ports.

  From this state, in S1, the first end stitch 11 locked to the knitting needle A of BD is moved to the knitting needle A of the upper front needle bed (FU) and the first adjacent stitch locked to the knitting needle B of BD Move 12 to the knitting needle B of FU. This S1 is a preparatory step (part of the step A of the present invention) for forming a first stitch 13 (see S4) in which the first end stitch 11 and the first adjacent stitch 12 are overlapped.

  In S2, the first end stitch 11 is moved to the knitting needle B of BD, and in S3, the first adjacent stitch 12 is moved to the knitting needle B of BD (the remaining part of the process A of the present invention). As a result, as shown in S4, a first stitch 13 in which the first end stitch 11 is overlapped is formed on the front side of the first adjacent stitch 12 (outside of the sweater 100 in FIG. 1). The yarn feeding member 9 is disposed closer to the one end side LS than the first end stitch 11 while the first stitch 13 is formed in S1 to S3. Therefore, since the knitting yarn extending from the yarn feeding member 9 does not get tangled in the first end stitch 11 or the first adjacent stitch 12, the joint portion 55 (FIG. 1) can be finished neatly.

  Here, the first end stitch 11 can also be superimposed on the back side of the first adjacent stitch 12 (the inner side of the sweater 100 in FIG. 1). In that case, it is sufficient to move only the first end stitch 11 in S1 and to overlap the moved first end stitch 11 on the first adjacent stitch 12 locked to the knitting needle B of BD. When the first end stitch 11 is overlapped on the back side of the first adjacent stitch 12, the appearance of the joint portion is slightly inferior to that of overlapping the first end stitch 11 on the front side of the first adjacent stitch 12. However, when the knitted fabric parts 1 and 2 of the rib structure are contracted, the slightly inferior appearance hides in a position invisible from the outside of the sweater 100 (FIG. 1). If it is desired to improve the appearance of the joint even when the knitted fabric parts 1 and 2 of the rib structure are stretched, the first end stitch 11 is overlapped on the front side of the first adjacent stitch 12 as shown in S1 to S3. It is good.

  In S4, the yarn supplying member 9 arranged on one end side LS of the first end stitch 11 in S1 is moved to the other end side RS of the first mesh 13. In S5, the yarn supplying member 9 is moved. It is moved to the one end side LS, and a new stitch 14 continuing in the wale direction of the first stitch 13 is formed (corresponding to step B of the present invention). The new stitch 14 is a new first end stitch 11 on one end side LS of the first knitted fabric portion 1 in the knitting width direction. By knitting a new stitch 14 when the yarn feeding member 9 is moved to the one end side LS, it is possible to avoid that the new stitch 14 becomes a twisted stitch.

  In S6, the second end stitch 21 locked to the knitting needle A of the FD is moved to the knitting needle A of the upper rear needle bed (BU), and the second adjacent stitch 22 locked to the knitting needle B of the FD is BU Move to the knitting needle B of This S6 is a preparatory step (part of the step C of the present invention) for forming a second stitch 23 (see S9) in which the second end stitch 21 and the second adjacent stitch 22 are overlapped.

  At S7, the second end stitch 21 is moved to the knitting needle B of the FD, and at S8, the second adjacent stitch 22 is moved to the knitting needle B of the FD (the remaining part of the process C of the present invention). As a result, as shown in S9, the second stitch 23 in which the second end stitch 21 is overlapped is formed on the front side of the second adjacent stitch 22.

  Here, as in the case where the first end stitch 11 and the first adjacent stitch 12 are overlapped, the second end stitch 21 can be overlapped on the back side of the second adjacent stitch 22. In that case, it is sufficient to move only the second end stitch 21 in S6 and to overlap the moved second end stitch 21 on the second adjacent stitch 22 locked to the knitting needle B of the FD.

  At S9, the yarn supplying member 9 disposed at one end LS of the second end stitch 21 at S6 is moved to the other end RS of the second stack 23. At S10, the yarn supplying member 9 is moved. It is moved to the one end side LS, and a new stitch 24 continuing in the wale direction of the second stitch 23 is formed (corresponding to step D of the present invention). The new stitch 24 is a new second end stitch 21 on one end side LS of the second knitted fabric portion 2 in the knitting width direction, and is knitted when the yarn feeding member 9 is moved to the one end side LS It is not a twisted eye.

  In a series of knitting S1 to S10, the first adjacent stitch 12 of the first knitted fabric part 1 and the second adjacent stitch 22 of the second knitted fabric part 2 are the new first end stitch 11 (S5) A new second end stitch 21 (S10) is connected by a connecting yarn. Both adjacent stitches 12 and 22 of S1 are back eyes, and the back eyes of the first knitted fabric portion 1 and the back stitches of the second knitted fabric portion 2 are connected.

  Also in S11 to S20 of FIG. 3, steps A to D of the present invention are repeated as in S1 to S10 of FIG. 2. However, in S11 to S20 of FIG. 3, since the first adjacent stitch 12 adjacent to the first end stitch 11 and the second adjacent stitch 22 adjacent to the second end stitch 21 are both front faces, the adjacent stitch 12 The end stitch 11 (21) is overlapped on the back side of (22), and a new stitch 14 (24) continuing in the wale direction of the stitch 13 (23) is a back stitch.

  In S11, the first end stitch 11 of the knitting needle B of BD is moved to the knitting needle C of FU, and in S12, the first adjacent stitch 12 of the knitting needle C of BD is moved to the knitting needle C of FU The stack 13 (S13) is formed (corresponding to step A of the present invention).

  In S13, the yarn feeding member 9 is moved to the other end side RS, and in S14, the yarn feeding member 9 is moved to the one end side LS and a new stitch 14 continues in the wale direction of the first stack 13 (new first The end stitches 11) are knitted with a back stitch (corresponding to step B of the present invention). In S15, the new first end stitch 11 is moved to the knitting needle C of BD in a state where the yarn feeding member 9 is stopped at the one end side LS which is the knitting start side.

  In S16, the second end stitch 21 of the knitting needle B of FD is moved to the knitting needle C of BU, and in S17, the second adjacent stitch 22 of the knitting needle C of FD is moved to the knitting needle C of BU and the knitting needle C is secondly The stack 23 (S18) is formed (corresponding to step C of the present invention).

  In S18, the yarn feeding member 9 is moved to the other end side RS, and in S19, the yarn feeding member 9 is moved to the one end side LS and a new stitch 24 continues in the wale direction of the second stack 23 (new second The end stitches 21) are knitted with the back stitch (corresponding to step D of the present invention). In S20, the new second end stitch 21 is moved to the knitting needle C of the FD while the yarn feeding member 9 is stopped at the one end side LS.

  In a series of knitting of S11 to S20, the first adjacent stitch 12 of the first knitted fabric part 1 and the second adjacent stitch 22 of the second knitted fabric part 2 have a new first end stitch 11 (S14) A new second end stitch 21 (S19) is connected by a connecting yarn. Both adjacent stitches 12 and 22 of S11 are front eyes, and the front eyes of the first knitted fabric portion 1 and the front eye of the second knitted fabric portion 2 are connected.

  After that, the first knitted fabric portion 1 and the second knitted fabric portion can be joined by repeating the same knitting as in S1 to S20. The joint between the first knitted fabric portion 1 and the second knitted fabric portion 2 joined by the method of joining the knitted fabrics described above is flat and has an extremely excellent appearance.

The above joining method can be used to join the first knitted fabric portion 1 and the second knitted fabric portion 2 having an n × m rib structure including the 1 × 1 rib structure described in FIGS. m is an arbitrary natural number). Regardless of what the numbers n and m are, by sequentially repeating the steps A to D so as to satisfy the following conditions, it is possible to flatten the joint between the two knitted fabric parts 1 and 2.
[Condition 1] When the First Adjacent Stitch 12 (Second Adjacent Stitch 22) is the Front Eye In Step A (Step C), the yarn feeding member 9 is more than the first end stitch 11 (second end stitch 21) The first end stitch 11 (second end stitch 21) is superimposed on the back side of the first adjacent stitch 12 (second adjacent stitch 22) in a state of being disposed on the one end side LS, and a first stitch 13 (second stitch) Form 23). In step B (step D), a new first end stitch 11 (second end stitch 21) to be a back stitch is knitted.
[Condition 2] When the first adjacent stitch 12 (second adjacent stitch 22) is a back stitch In step A (step C), the yarn feeding member 9 is one end more than the first end stitch 11 (second end stitch 21) The first end stitch 11 (second end stitch 21) is superimposed on the front side or the back side of the first adjacent stitch 12 (second adjacent stitch 22) in a state of being disposed on the side LS to form a first stitch 13 (second lap Form the eye 23). In step B (step D), a new first end stitch 11 (second end stitch 21) to be a front stitch is knitted.

  Here, the photograph of the knitted fabric which joined the 1st knitted fabric part and 2nd knitted fabric part which have rib structure of 2x2 using the joining method of the knitted fabric shown to embodiment is shown in FIG. As shown in FIG. 4 (A), the junction is formed straight without waves, making the fabric look extremely good. Moreover, as shown to FIG. 4 (B), even if it extends a knitted fabric and extends a junction part, it turns out that rib tissue of back and front is connected beautifully in a junction part. On the other hand, in the knitted fabric using the joining method of the knitted fabric of Patent Document 1 shown in FIG. 5, the joint portion is bent so as to be violently wavy and compared with the knitted fabric of FIG.
