Description

The present invention relates to a knitted fabric knitting method in which a rear knitted fabric portion is knitted on a rear needle bed by a front yarn feeder, a front knitted fabric portion is knitted on a front needle bed by a rear yarn feeder, and the two knitted fabric portions are joined.

For example, Patent Document 1 discloses a method of knitting a knitted fabric by knitting a rear knitted fabric portion on a rear needle bed with a front yarn feeder and knitting a front knitted fabric portion on a front needle bed with a rear yarn feeder. . The front needle bed and the rear needle bed face each other. The front yarn feeder is arranged closer to the front needle bed than the rear yarn feeder. The front yarn feeder feeds the first knitting yarn, and the rear yarn feeder feeds the second knitting yarn. The first knitting yarn and the second knitting yarn intersect at the ends in the knitting width direction of the front knitted fabric portion and the rear knitted fabric portion depending on the positional relationship between the front yarn feeder and the rear yarn feeder and the order of movement of both yarn feeders. . The crossing of the knitting yarns joins the front knitted fabric portion and the rear knitted fabric portion. Further, in Patent Document 1, by forming a miss pattern on the left and right boundaries between the front knitted fabric portion and the back knitted fabric portion, the intersection of the knitting yarns is made inconspicuous and the left and right boundaries look the same.

JP 2010-53490 A

The miss pattern formed at the boundary between the front knitted fabric portion and the rear knitted fabric portion may be conspicuous depending on the texture pattern of both knitted fabric portions. In that case, there is a need to obscure the intersection of knitting yarns at the boundary by a knitting method different from the knitting method of Patent Document 1.

One of the objects of the present invention is to provide a method of knitting a knitted fabric in which crossing of knitting yarns for joining a front knitted fabric portion and a rear knitted fabric portion can be made inconspicuous.

The knitting method of the knitted fabric of the present invention comprises:
Using a flat knitting machine comprising a front needle bed, a back needle bed facing the front needle bed, a front yarn feeder feeding a first knitting yarn, and a rear yarn feeder feeding a second knitting yarn hand,
By knitting the back knitted fabric portion on the back needle bed by the front side yarn feeder and knitting the front knitted fabric portion on the front needle bed by the back side yarn feeder, the knitting width direction of the front knitted fabric portion and the back knitted fabric portion is knitted. In the knitting method of a knitted fabric, the first knitting yarn and the second knitting yarn are crossed at the end of to join the front knitted fabric portion and the rear knitted fabric portion,
When the first knitting yarn and the second knitting yarn are crossed, knitting is performed so that one of the end stitches of the front knitted fabric portion and the end stitch of the back knitted fabric portion is a back stitch and the other is a front stitch.

As one embodiment of the knitting method of the knitted fabric of the present invention,
The flat knitting machine comprises a carriage on which four cam systems are mounted,
A mode in which the front knitted fabric portion and the rear knitted fabric portion are knitted while the carriage is moved in one direction is exemplified.

According to the knitting method of the knitted fabric of the present invention, when the first knitting yarn and the second knitting yarn are crossed, the front stitch and the back stitch are arranged across the boundary between the front knitted fabric portion and the rear knitted fabric portion. As a result, a step is formed between the front stitch and the back stitch at the position of the boundary between the two knitted fabric portions. Intersections of knitting yarns are easily hidden in this level difference. Therefore, in the knitted fabric obtained by the knitting method of the present invention, the crossing of the knitting yarns joining the front knitted fabric portion and the rear knitted fabric portion is inconspicuous. In addition, the step formed by arranging the front stitches and the back stitches is less conspicuous than the mistake pattern of Patent Document 1.

By knitting the front knitted fabric portion and the rear knitted fabric portion while moving the carriage in one direction, the knitted fabric is knitted very efficiently. For example, when the front knitted fabric portion and the rear knitted fabric portion are knitted by circular knitting using one yarn feeder, the carriage must be reciprocated.

FIG. 1 is a schematic diagram of a carriage with four cam systems. FIG. 2 is a first knitting process diagram of the knitting method of the knitted fabric according to the first embodiment. FIG. 3 is a second knitting process diagram following FIG.

A method of knitting a knitted fabric according to the embodiment will be described below with reference to the drawings.

<Embodiment 1>
In this embodiment, an example of the knitting method of the knitted fabric of the present invention using a four-bed flat knitting machine will be described with reference to the drawings.

A four-bed flat knitting machine includes a lower front needle bed, a lower back needle bed, an upper front needle bed, and an upper back needle bed. The lower front needle bed, the lower back needle bed, the upper front needle bed, and the upper back needle bed are hereinafter referred to as FD, BD, FU, and BU, respectively. FD and BD face each other. The FU arranged above the FD and the BU arranged above the BD face each other. The four-bed flat knitting machine further comprises a plurality of yarn feeders and a carriage. The relationship between the needle bed, the yarn feeder and the carriage will be briefly described with reference to the schematic diagram of FIG.

FIG. 1 is a schematic diagram of a portion of the flat knitting machine 5 viewed from the FD side. Illustration of the FU is omitted in FIG. A carriage 6 provided in the flat knitting machine 5 reciprocates on the needle bed. The carriage 6 of this example comprises four cam systems 6A, 6B, 6C, 6D arranged in the longitudinal direction of the needle bed. Each cam system has cams corresponding to FD, BD, FU, and BU. 1 also shows a front yarn feeder 8 arranged on the FD and FU side and a rear yarn feeder 9 arranged on the BD and BU side of the front yarn feeder 8 among the plurality of yarn feeders. ing. The yarn feeders 8 and 9 are movably attached to a rail 7 arranged above the needle bed.

Next, an example of a method of knitting a knitted fabric using the flat knitting machine 5 shown in FIG. 1 will be described with reference to FIGS. 2 and 3. FIG. "S+Number" in the left column of FIGS. 2 and 3 indicates the number of the knitting process. The right column shows the knitting state of the stitches in each knitting process. A black dot in the right column indicates a knitting needle, and an inverted triangular mark indicates a front yarn feeder 8 or a rear yarn feeder 9 . A straight arrow indicates the transfer. The stitches newly knitted in each knitting process are indicated by thick lines.

S0 in FIG. 1 shows a state in which the front knitted fabric portion 2 is locked to the FD and the rear knitted fabric portion 3 is locked to the BD. The front knitted fabric portion 2 is knitted with the second knitting yarn 9Y fed from the rear yarn feeder 9 . The rear knitted fabric portion 3 is knitted with the first knitting yarn 8Y fed from the front yarn feeder 8 . In this example, the knitting method of the knitted fabric of the present invention is carried out at the right and left ends of the knitted fabric 1 from the state S0 to knit the tubular knitted fabric 1 . The knitted fabric 1 is knitted by full needle knitting. Full-needle knitting means knitting without empty needles between adjacent stitches.

In S1, the rear yarn feeder 9 is moved rightward, and a new front knitted fabric portion 2 is knitted. All the stitches of the new front knitted fabric portion 2 are front stitches. The front stitch is a stitch pulled out from the old stitch toward the outside from the inside of the tubular knitted fabric 1 . Unlike this example, the back knitted fabric portion 3 may be knitted first.

In S2, of the left end stitch 3L and the right end stitch 3R in the knitting width direction of the back knitted fabric portion 3, the right end stitch 3R is transferred from BD to FU. The stitches other than the end stitch 3R in the back knitted fabric portion 3 remain retained on the BD.

In S3, the front yarn feeder 8 is moved rightward, and a new back knitted fabric portion 3 is knitted. In the new back knitted fabric portion 3, the right end stitch 3R is a back stitch, and the stitches other than the end stitch 3R are front stitches. A back stitch is a stitch that is pulled out from an old stitch from the outside toward the inside of the tubular knitted fabric 1 . As a result of S3, the first knitting yarn 8Y and the second knitting yarn 9Y intersect on the outer side of the knitted fabric 1 in the knitting width direction.

In S4, the end stitch 3R of the back knitted fabric portion 3 formed in the FU in S3 is transferred to the BD. By S4, all the stitches of the front knitted fabric portion 2 are held on the FD, and all the stitches of the rear knitted fabric portion 3 are held on the BD. The end stitch 2R and the end stitch 3R are arranged at positions sandwiching the boundary between the front knitted fabric portion 2 and the back knitted fabric portion 3 on the right side of the drawing. The end stitch 2R is a front stitch, and the end stitch 3R is a back stitch.

The knitting indicated by S1 to S4 is performed by moving the carriage 6 (see FIG. 1) in one direction. Specifically, the knitting of S1, S2, S3, and S4 is performed by cam system 6A, cam system 6B, cam system 6C, and cam system 6D mounted on carriage 6, respectively. That is, by moving the carriage 6 in one direction, the knitting of the front knitted fabric portion 2, the transfer of the end stitch 3R of the back knitted fabric portion 3 on the traveling direction side of the carriage 6, the knitting of the back knitted fabric portion 3, and the end stitch 3R are performed. are returned to the original needle bed in this order.

In S5 of FIG. 3, of the left end stitch 2L and the right end stitch 2R in the knitting width direction of the front knitted fabric portion 2, the left end stitch 2L is transferred from FD to BU. The stitches other than the end stitches 2L in the front knitted fabric portion 2 remain held by the FD.

In S6, the rear yarn feeder 9 is moved leftward, and a new front knitted fabric portion 2 is knitted. The left end stitch 2L of the new front knitted fabric portion 2 is a back stitch, and the stitches other than the end stitch 2L are front stitches. As a result of S6, the first knitting yarn 8Y and the second knitting yarn 9Y that cross each other at the right end of the knitted fabric 1 are entwined, and the front knitted fabric portion 2 and the rear knitted fabric portion 3 are joined.

In S7, the end stitch 2L formed in the BU in S6 is transferred from the BU to the FD.

In S8, the front yarn feeder 8 is moved leftward, and a new back knitted fabric portion 3 is knitted. All the stitches of the new back knitted fabric portion 3 are front stitches. Therefore, the end stitch 2L and the end stitch 3L sandwiching the boundary between the front knitted fabric portion 2 and the back knitted fabric portion 3 on the left side of the page are the back stitch and the front stitch, respectively. Unlike this example, one of the right end stitch of S6 and the right end stitch of S8 may be the front stitch and the other may be the back stitch.

The knitting indicated by S5 to S8 is performed by moving the carriage 6 (see FIG. 1) in one direction. Specifically, the knitting of S5, S6, S7, and S8 is performed by cam system 6D, cam system 6C, cam system 6B, and cam system 6A mounted on carriage 6, respectively. That is, by moving the carriage 6 in one direction, the end stitch 2L of the front knitted fabric portion 2 on the traveling direction side of the carriage 6 is transferred, the front knitted fabric portion 2 is knitted, and the end stitch 2L is transferred to the original needle bed. Knitting of the back knitted fabric portion 3 is performed in this order.

After S8, by repeating the same knitting as S1 to S8, a tubular knitting having the front knitted fabric portion 2 and the rear knitted fabric portion 3 joined by the crossing of the first knitting yarn 8Y and the second knitting yarn 9Y is performed. You can organize the ground 1. In this knitted fabric 1, front stitches and back stitches are arranged with the boundary between the front knitted fabric portion 2 and the rear knitted fabric portion 3 interposed therebetween. As a result, a step is formed between the front stitch and the back stitch at the boundary position. The intersection of the knitting yarns 8Y and 9Y is likely to be hidden by this step. Therefore, in the knitted fabric 1 obtained by the knitting method of the knitted fabric of the present invention, the crossing of the knitting yarns 8Y and 9Y that join the front knitted fabric portion 2 and the rear knitted fabric portion 3 is inconspicuous. The step is less conspicuous than the incorrect pattern of Patent Document 1.

Here, if the front stitches and the back stitches are arranged across the boundary between the front knitted fabric portion 2 and the back knitted fabric portion 3, the crossing of the knitting yarns 8Y and 9Y at the boundary is less conspicuous. Therefore, the combination of the front stitches and the back stitches at the boundary is not limited to the combination of the back stitches for the end stitches 2L and 3R and the front stitches for the end stitches 2R and 3L illustrated in FIGS. For example, the end stitches 2L and 3R may be front stitches, and the end stitches 2R and 3L may be back stitches.

According to the knitting method of the knitted fabric of this example, the front knitted fabric portion 2 and the rear knitted fabric portion 3 can be knitted by two stages while the carriage 6 is reciprocating once. Also, in this example, there is no empty course where only the carriage 6 is moved. Therefore, the knitted fabric 1 can be completed efficiently.

<Other embodiments>
In the embodiment, the front knitted fabric portion 2 and the back knitted fabric portion 3 have a jersey weave, but may have a weave pattern such as a rib weave or a garter weave. For example, the front knitted fabric portion 2 and the rear knitted fabric portion 3 may have a rib structure. In that case, it is preferable to transfer some of the stitches of the back knitted fabric portion 3 to FU in S2 and transfer some of the stitches of the front knitted fabric portion 2 to BU in S5. If not only the end stitches 2L and 3R but also the stitches adjacent to the end stitches 2L and 3R are purl stitches like the rib structure, the intersection of the knitting yarns 8Y and 9Y can be more easily hidden by the steps.

The front knitted fabric portion 2 and the rear knitted fabric portion 3 may be knitted in a C shape. In this case, the knitted fabric portions 2 and 3 are joined at one end in the knitting width direction of the knitted fabric portions 2 and 3, and the knitted fabric portions 2 and 3 are not joined at the other end.

The knitting method of the knitted fabric of the present invention can also be carried out by a flat knitting machine equipped with two or three cam systems. Further, the knitting method of the knitted fabric of the present invention can also be carried out by a two-bed flat knitting machine. When using a two-bed flat knitting machine, the front knitted fabric portion and the rear knitted fabric portion are knitted by needleless knitting. Needle-free knitting means knitting with empty needles arranged between adjacent stitches. Empty needles arranged between adjacent stitches are used for stitch transfer and stitch formation.
