Japanese Patent Laid-Open No. 2003-73961

  In recent years, with the diversification of fashion, there has been a demand for a knitting method of a knitted fabric that more efficiently knits a tubular portion having a rib structure. On the other hand, in the conventional method shown in FIG. 2, the movement of the carriage is performed three times to form the rib structure on the one side knitted fabric portion 1F and to knitting the rib structure on the other side knitted fabric portion 1B. Three times, that is, a total of six times was required to knit the cylindrical portion 1 by one stage.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a knitting method of a knitted fabric capable of knitting a cylindrical portion having a rib structure more efficiently than in the past.

  As a result of intensive studies on the above problems, the present inventor has conceived that a plurality of yarn feeders provided in a flat knitting machine are used, and has completed the present invention. The present invention is defined below.

The present invention comprises at least a pair of front and rear needle beds, a first yarn feeder and a second yarn feeder for feeding knitting yarn to the knitting needles of each needle bed, and is capable of transferring stitches between the front and rear needle beds. The present invention relates to a knitting method of a knitted fabric using a knitting machine and knitting a rib structure on at least a part of a tubular portion including a knitted fabric portion on one side and a knitted fabric portion on the other side. In the knitting method of the knitted fabric of the present invention, from the state where the first yarn feeder and the second yarn feeder are arranged at positions sandwiching the cylindrical portion that is locked to the needle bed, the following steps α to δ are performed. It is characterized by performing.
[Step α]... The stitches of the one side knitted fabric portion locked to one needle bed are arranged on one needle bed and the other needle bed by transfer.
[Step β]... The first yarn feeder is moved to the second yarn feeder, and the rib structure is knitted on the one side knitted fabric portion.
[Step γ]... The second yarn feeder is moved away from the first yarn feeder, and a rib structure is knitted on the one side knitted fabric portion.
[Step δ] In the rib structure of the one side knitted fabric portion knitted in step γ, the stitches locked to the other needle bed are transferred to one needle bed.

  As one form of the knitting method of the knitted fabric of the present invention, when knitting the rib structure on the other knitted fabric portion locked to the other needle bed, the same knitting as in the steps α to δ is performed. be able to. The steps α to δ of the other side knitted fabric portion are the “one side knitted fabric portion”, “one needle bed”, and “the other needle bed” in the steps α to δ of the one side knitted fabric portion. Each may be read as “other side knitted fabric portion”, “other needle bed”, and “one needle bed”.

  As one form of the knitting method of the knitted fabric of the present invention, there is a form in which the steps α to δ are repeated for the one side knitted fabric portion and the steps α to δ are repeated for the other side knitted fabric portion. be able to. In that case, the process δ of the n-th one-side knitted fabric part and the process α of the n-th other-side knitted fabric part are simultaneously performed, and the process δ of the n-th other-side knitted fabric part and the n + 1-th one-side knitting The ground portion process α is performed simultaneously. However, n is a natural number of 1 or more.

  According to the knitting method of the knitted fabric of the present invention, the rib structure can be knitted on the tubular portion more efficiently than the conventional knitting method of the knitted fabric. For example, as shown in the first embodiment to be described later, when the knitting method of the knitted fabric of the present invention is performed using one composite cam system, each of the steps α to δ is performed by one movement of the carriage. It corresponds to the operation that can be. That is, in the knitting method of the knitted fabric according to the present invention, the one side knitted fabric portion can be knitted in two stages by moving the carriage four times. On the other hand, in the conventional knitting method of the knitted fabric shown in FIG. 2, the one side knitted fabric portion is knitted by one stage by moving the carriage three times. Movement of the carriage is required. As described above, the knitting method of the knitted fabric of the present invention has a smaller number of carriage movements (that is, the number of knitting steps) than the knitting method of the conventional knitted fabric, and is more efficient than the knitting method of the conventional knitted fabric. A cylindrical portion having a rib structure can be knitted.

  By knitting the rib structure of the other side knitted fabric part in addition to the knitting of the rib structure of the one side knitted fabric part, the rib structure is formed on both the one side knitted fabric part and the other side knitted fabric part by performing steps α to δ. The formed cylindrical portion can be knitted more efficiently than the conventional method.

  By performing the steps α and δ of both knitted fabric portions simultaneously with one movement of the carriage, as shown in an embodiment described later, the one side knitted fabric portion and the other side knitted fabric with a total of six movements of the carriage. The ground part can be knitted in two steps.

It is a knitting process figure of the cylindrical part which has the rib structure | tissue which concerns on embodiment. It is a knitting process figure of the cylindrical part which has a rib structure | tissue which concerns on a prior art.

  Hereinafter, embodiments according to the knitting method of the knitted fabric of the present invention will be described. In the embodiment, one needle bed (hereinafter referred to as FB) and the other needle bed (hereinafter referred to as BB) extending in the left-right direction and facing each other in the front-rear direction, and at least two yarn feeders, FB and BB, An example of knitting using a two-bed flat knitting machine capable of transferring stitches between the two will be described.

<Embodiment 1>
In Embodiment 1, a knitting method of a knitted fabric of the present invention using one composite cam system will be described with reference to FIG. The view of FIG. 1 is the same as FIG. 2 used for description of the conventional knitting method of the knitted fabric.

  In S0 of FIG. 1, one side knitted fabric portion 1F of the tubular portion 1 is locked to the knitting needles A, C, E, G, and I of the FB, and the knitting needles B, D, F, H, and J of the BB are tubular. A state in which the other knitted fabric portion 1B of the shape portion 1 is locked is shown. At this time, the first yarn feeder 8 is disposed on the left side of the sheet with the tubular portion 1 interposed therebetween, and the second yarn feeder 9 is disposed on the right side of the sheet. Although not shown, the carriage is on the right side of the page.

  In S1, the carriage is moved in the left direction, and the stitches of the one side knitted fabric portion 1F locked to the knitting needles C and G of the FB are transferred to BB (step α of the one side knitted fabric portion 1F). The stitch transfer performed in S1 is for knitting a 1 × 1 rib structure over the entire width in the knitting width direction of the one side knitted fabric portion 1F. By changing the stitches to be transferred, the rib structure knitted on the one side knitted fabric portion 1F is changed to a rib structure other than the 1 × 1 rib structure (a structure including at least one back stitch and combined with the front stitch). You can also. Of course, the rib structure can be knitted only in a part of the knitting width direction of the one side knitted fabric portion 1F.

  In S2, the carriage is moved in the right direction, and the knitting yarn is alternately fed from the first yarn feeder 8 to the knitting needles A, E, I of the FB and the knitting needles C, G of the BB. The knitted fabric portion 1F is knitted (step β of the one side knitted fabric portion 1F). By this S2, the first yarn feeder 8 is moved to the second yarn feeder 9 side (right side).

  In S3, the carriage is moved to the left, and the knitting yarns are alternately fed from the second yarn feeder 9 to the knitting needles A, E, I of the FB and the knitting needles C, G of the BB, so The knitted fabric portion 1F is knitted (step γ of the one side knitted fabric portion 1F). By this S3, the second yarn feeder 9 is moved to the side away from the first yarn feeder 8 (left side).

  In S4, the carriage is moved rightward, and in S3, the stitches of the rib structure of the one side knitted fabric portion 1F formed on the knitting needles C and G of the BB are transferred to the knitting needles C and G of the FB (one side knitted fabric). Step δ) of part 1F. In S4, among the stitches of the other side knitted fabric portion 1B, the stitches locked to the knitting needles B, F, J of the BB are transferred to the knitting needles B, F, J of the FB (the other side knitted fabric portion 1B). Step α). In addition, the stitch of the other side knitted fabric portion 1B transferred at S4 can be appropriately changed according to the rib structure formed on the other side knitted fabric portion 1B, similarly to the one side knitted fabric portion 1F of S1.

  In S5, the carriage is moved in the left direction, and the knitting yarns are alternately fed from the first yarn feeder 8 to the knitting needles B, F, J of the FB and the knitting needles D, H of the BB. The knitted fabric portion 1B is knitted (step β of the other side knitted fabric portion 1B). By this S5, the first yarn feeder 8 is moved to the second yarn feeder 9 side (left side).

  In S6, the carriage is moved in the right direction, and the knitting yarns are alternately fed from the second yarn feeder 9 to the knitting needles B, F, J of the FB and the knitting needles D, H of the BB. The knitted fabric portion 1B is knitted (process γ of the other side knitted fabric portion 1B). By this S6, the second yarn feeder 9 is moved to the side away from the first yarn feeder 8 (right side).

  Henceforth, by repeating S1-S6, the knitted fabric provided with the cylindrical part which has a rib structure | tissue can be knitted. However, the other side knitted in the nth S6 (step δ of the other side knitted fabric portion 1B) before performing the n + 1th time (n is a natural number of 1 or more) S2 (step β of the one side knitted fabric portion 1F). Among the stitches of the knitted fabric portion 1B, the stitches locked to the FB must be transferred to the BB. Transfer of the stitches of the other side knitted fabric portion 1B may be performed simultaneously with the transfer of the one side knitted fabric portion 1F (step α of the one side knitted fabric portion 1F) in the n-th S1.

  According to the knitting process described above, the one-side knitted fabric portion 1F and the other-side knitted fabric portion 1B can be knitted by two stages by moving the carriage six times. This is markedly different from the conventional knitting method with reference to FIG. 2 in which the one side knitted fabric portion 1F and the other side knitted fabric portion 1B can be knitted only one step at a time by six carriage movements. Efficient.
