Description

  The present invention relates to knitting of a tubular knitted fabric, and more particularly to knitting of a tubular knitted fabric in which sleeves are connected asymmetrically in the longitudinal direction.

The inventor has proposed a method for knitting asymmetric knitwear (Patent Document 1: Japanese Patent Laid-Open No. 2005-23440, Patent Document 2: Japanese Patent Laid-Open No. 2005-54296). In these prior patents, the size of the sleeves is asymmetrical in the front and back, and the sleeves on the front sleeve side are made smaller than the sleeves on the rear sleeve side. By forming a large gusset, the sleeve is moved toward the front body. However, in the case of an asymmetrical sleeve mountain and an asymmetrical gusset, the sleeve is connected to the boundary between the front body and the back body, and it is difficult to connect the sleeve completely within the front body. For example, when the sleeve mountain is made asymmetrical in the front-rear direction, a large sleeve mountain on the rear side protrudes to the front side, but the rear part of the sleeve is connected to the back body. If the front gusset is made larger than the rear side, the sleeves will approach the front side, but the sleeves are still connected to both the front and back bodies. Patent Document 3 (US Pat. No. 6,216,494) proposes to move the tubular knitted fabric of the thumb toward the glove body and connect the thumb to the glove body.
JP-A-2005-23440 JP-A-2005-54296 USP 6216494

An object of the present invention is to enable knitting of knitwear or the like in which a sleeve is connected to the inside of the front body.
An additional problem in the present invention is to reduce yarn breakage accompanying movement of the knitted fabric.

In the knitting method of the asymmetrical tubular knitted fabric of the present invention,
a: A first tubular knitted fabric having a relatively large knitting width is disposed at the center in the left-right direction of at least two needle beds of the flat knitting machine, and a relatively small knitting width is provided on the left and right sides of the needle bed. 2, the third tubular knitted fabric is arranged, and one of the front and rear knitted fabrics in the first to third knitted fabrics is arranged on the first needle bed, and the other front and rear in the first to third knitted fabrics. Arranging each of the knitted fabrics on the second needle bed,
b: Move one of the front and rear knitted fabrics of the first tubular knitted fabric from the left and right sides toward the center of the first needle bed to reduce the knitting width and Rotating the left and right ends of the other front and rear knitted fabrics from the second needle bed to the left and right of the one knitted fabric at the first needle bed;
c: The second and third tubular knitted fabrics are rotated and moved from the first needle bed to the second needle bed respectively before and after the second and third tubular knitted fabrics. Are arranged to the left and right of the other knitted fabric before and after the knitted fabric, and are rotated to the first needle bed to the side of the empty needle generated by the rotational movement of one of the knitted fabric before and after the second and third tubular knitted fabrics Further increasing the knitting width by moving the left and right ends and further moving the knitted fabric having a reduced knitting width to the left and right of the first needle bed;
d: joining the other knitted fabrics before and after the second and third tubular knitted fabrics to the left and right of the knitted fabric main body excluding the left and right ends from the other knitted fabric in the first tubular knitted fabric Knitting at least the knitted fabric body;
e: The left and right ends are rotationally moved to the second needle bed, and the front and rear knitted fabrics of the second and third tubular knitted fabrics are joined to the left and right ends, and at least the left and right ends are knitted. And arranging the left and right ends on the left and right of the knitted fabric body,
f: joining the left and right ends and the knitted fabric body;
And do.

  Preferably, when the knitting width is reduced in the step b, about half of the stitches on one of the front and rear sides of the first knitted fabric are locked to the empty needles on the first needle bed, and the knitting is performed in the step c. When increasing the width, a blank needle is provided between the stitches of one of the knitted fabrics before and after the first knitted fabric.

Preferably, between step b and step c,
g: A gusset is formed by the stitches of the left and right ends and the stitches of one of the front and rear knitted fabrics in the second and third knitted fabrics, and the stitches of the knitted fabric body and the second and third knitted fabrics A step of forming gussets with the stitches of the other knitted fabric before and after the step is performed.
Particularly preferably, step c is performed twice in the order of step a, step b, step g, step c, step d, step c, step e, and step f.
In the present invention, the order of the knitting steps can be changed as appropriate except for the case where the order naturally occurs in order to execute the knitting, such as the need to reduce the knitting width of the back body first.

For example, the terms in the present invention correspond to the examples and the like as follows.

First tubular knitted fabric: body
Second and third tubular knitted fabrics: Both sleeves One front and back knitted fabric: Rear body, both rear sleeves The other front and rear knitted fabric: Front body, both front sleeves First needle bed: Rear needle bed (front needle bed But it is possible)
Second needle bed: Front needle bed (possible with back needle bed)
Left and right ends of the front body: The part that has moved to the first needle bed in the front body
Knitted fabric body (front body): The part that did not move to the first needle bed in the front body

In this invention, in step b, the knitting width of, for example, the back knitted fabric of the first tubular knitted fabric is reduced. Here, the knitting width is reduced by moving the rear knitted fabric from the left and right within the first needle bed toward the center of the knitted fabric. It is sometimes referred to as moving the knitted fabric to the left and right of the same needle bed. By reducing the knitting width of the back knitted fabric, the left and right ends of the other knitted fabric before and after the first tubular knitted fabric are turned into the spaces formed on the left and right sides of the back knitted fabric of the first needle bed. Moving the knitted fabric between the two needle beds so as to rotate clockwise or counterclockwise is referred to as rotational movement or turning.
Next, in step c, for example, the back knitted fabric of the second and third knitted fabrics such as both sleeves is rotated from the first needle bed to the second needle bed, and the first needle bed vacant space generated thereby is generated. The left and right ends of the first knitted fabric are moved to the space, and the knitting width of the knitted fabric and the like is increased after reducing the knitting width using the space generated by the movement of both ends.
In step d, for example, the front knitted fabric of the second and third knitted fabrics is joined to the knitted fabric main body.
Further, in step e, the left and right ends of the first knitted fabric are rotationally moved to the original needle bed, and, for example, the rear knitted fabric of the second and third knitted fabrics are joined to the left and right ends of the first knitted fabric. As a result, the left and right ends of the first knitted fabric are arranged on the left and right sides of the knitted fabric body on the second needle bed, and a part of the second and third knitted fabrics are joined to the left and right ends before rotating. May be.
As described above, since the second and third knitted fabrics are joined to, for example, the front knitted fabric of the first knitted fabric, when the left and right ends of the first knitted fabric are joined to the knitted fabric main body in Step f, And the joining of the third knitted fabric is completed.

In the present invention, two tubular knitted fabrics such as both sleeves can be connected to the inside of a larger tubular knitted fabric such as the body. Such a tubular knitted fabric can be used for animal clothing or diapers.
In order to reduce the knitting width, for example, a two-bed flat knitting machine may be used to lock the stitches to the empty needles used for cylindrical knitting. Further, stitches may be locked to an empty needle or a transfer jack in a four-bed flat knitting machine, and two stitches may be locked to one needle by holding using a composite needle.

Preferably, between step b and step c, a gusset is formed between the stitches at both left and right ends and the stitches of one of the front and rear knitted fabrics in the second and third knitted fabrics, and the stitches of the knitted fabric body A gusset is formed by the stitches of the other knitted fabric in the second and third knitted fabrics. Then, since these knitted fabrics can be connected to each other by using a plurality of stitches by gussets, it is possible to prevent yarn breakage when moving the stitches in subsequent operations.
After the formation of the gusset, for example, when the knitting width of the back knitted fabric is returned to the original width in one step, the gusset is stretched. Therefore, if step c is executed in two steps and executed in the order of step a, step b, step g, step c, step d, step c, step e, and step f, stitches generated by knitting in step d However, since it is interposed between the gusset and the knitted fabric body, the force applied to the gusset can be reduced.

  The best mode for carrying out the present invention will be described below, but the present invention is not limited to this.

  1 to 8 show a knitting method of a tubular knitted fabric in the embodiment. FIG. 1 shows a knitwear 1 to be knitted, and the knitwear 1 is an animal garment such as a dog. 2 is a front body, and there is a rear body (not shown) on the back. The left sleeve 3 and the right sleeve 4 are completely joined to the inside of the front body 2, and the rear of the sleeves 3 and 4 are visible in the figure. The sleeve part. 5 is a rib structure on the rear foot side, 6 is a rib structure on the neck side, and 7 and 8 are rib structures provided on the sleeves 3 and 4.

  FIG. 2 shows knitwear 11 such as a diaper, 12 is a front torso, a back torso (not shown) is provided on the back side, 13 is an abdominal rib tissue, and 14 and 15 are rib tissue feet.

  In the embodiment, knitwear in which the left and right sleeves and the left and right feet are joined together is completely knitted without sewing in the front body. The flat knitting machine used is a two-bed, one needle bed can be racked with respect to the other needle bed, and transfer between the needle beds is free. Instead of a two-bed flat knitting machine, a four-bed flat knitting machine may be used. In the embodiment, the front body and both front sleeves are knitted on the front needle bed, the back body and both rear sleeves are knitted on the back bed, knitted with a two-bed flat knitting machine, and one stitch between the stitches and stitches Prepare empty hands one by one. However, the front body and both front sleeves may be knitted with the back needle bed, and the back body and both back sleeves may be knitted with the front needle bed.

  3 to 7 show knitting of the tubular knitted fabric in the embodiment. In each figure, reference numeral 31 denotes a front body, which is knitted on a first needle bed (front needle bed), and 31a is a front body body, which is a portion where transfer from the front needle bed to the rear needle bed is not performed. 32 is a back body, which is knitted on the second needle bed (rear needle bed) and reduces the knitting width to about ½ by holding about half of the stitches to the empty needles in the process of joining the sleeves. . In the reduction of the knitting width, there is no meaning in the ratio itself that the width is reduced to ½, but it is meaningful in that both end portions 47 and 48 of the front body 31 are rotated and moved to the back body side. Therefore, it is not necessary to reduce the knitting width to exactly 1/2. 3 and 4 show the joining operation between the sleeve and the body. The body consisting of the front body 31 and the back body 32 is knitted in a cylindrical shape, and the left sleeve consisting of the left front sleeve 33 and the left rear sleeve 35 is similarly knitted in a cylindrical shape. Further, the right sleeve composed of the right front sleeve 34 and the right rear sleeve 36 is also knitted in a cylindrical shape, and these are arranged on the left and right of the body bodies 31 and 32 on the first and second needle beds at the start of joining of the sleeves. .

  The knitting width of the back body 32 is reduced to, for example, 1/2, and both end portions 47 and 48 of the front body 31 are rotated and moved to the back body 32 side. For example, in parallel with this, the left and right sleeves are moved to the body side (step 1). The rotational movement is to move the knitted fabric as if rotating by transferring between the needle beds and racking the needle beds. The rotational movement model is shown on the right side of step 1 in FIG. If the stitch at the outer end of the front body end 47 is E and the stitch at the boundary with the front body 31a is F, the connecting sequence with the front body 31a is maintained from the stitch E to the stitch F. As described above, the end 47 of the front body is moved to the rear needle bed.

  FIG. 6 schematically shows the reduction of the knitting width of the back body. About half of the stitches on the back body are moved to the front needle bed, the back needle bed is racked, and the stitches on the back body are transferred back to the back needle bed one by one. In parallel with this, the left and right stitches of the front body 31 are rotated and moved to the rear needle bed side. In this way, the knitting width of the back body 32 is reduced to about ½. On the front body side, the left and right end portions 47 and 48 are rotationally moved to the rear needle bed side, so that the knitting width on the front needle bed is reduced. Then, the knitting width of the back body is reduced, and both the left and right end portions 47 and 48 are moved to the rear needle bed, for example, and simultaneously, the left and right sleeves are moved toward the center of the front and back needle beds.

  Symbols A and a in FIG. 3 are stitches at the boundary between the front sleeve and the rear sleeve, and D and d are stitches at both ends of the back body 32. B and b are end stitches of the rear sleeves 35 and 36 on the back body side. Reference numerals 37 to 40 denote gusset forming portions which form gussets 50 between the front body 31a and the end 47 and the sleeves 33 and 35. A gusset 51 is formed between the front body 31a and the end 48 and the sleeves 34 and 36 (step 2). By forming the gusset, the body and both sleeves are joined in a wide range, so that yarn breakage when moving the stitches in the subsequent process can be prevented. Reference numerals 42 and 43 denote rotationally moving portions, which are composed of stitches that are locked to the needles on the rear needle bed even after the formation of the gussets 50 and 51 in the both end portions 47 and 48.

  After forming the gusset, the rear sleeves 35 and 36 are rotated and moved to the front sleeves 33 and 34 side, and the rotational movement parts 42 and 43 and the rear body 32 are moved to the space of the rear needle bed generated thereby, The knitting width of the body 32 is expanded (step 3). Next, the front sleeves 33 and 34 are joined to the front body 31a while moving to the front body 31a side, and for each joint, for example, one or more courses, the front body 31a is knitted to form a new stitch. . Since the number of stitches of the front sleeves 33 and 34 decreases, the rear sleeves 35 and 36 are further rotated to the front needle bed side to compensate for this (step 4).

  Since many courses of the front body 31a are knitted, stitches knitted on the front body 31a are interposed between the front body 31a and the gussets 50 and 51 in the process of joining the front sleeves. For this reason, even if the gussets 50 and 51 are further extended, there is no risk of thread breakage. Therefore, the rear sleeves 35 and 36 are completely rotated and moved to the front needle bed side, for example, and the rotational movement portions 42 and 43 are moved to the space of the rear needle bed generated thereby, so that the back body 32 is returned to the original knitting width, for example. Return (step 5).

  Next, the rotational movement parts 42 and 43 are joined while being moved toward the rear sleeves 35 and 36 on the front needle bed, and for each joint, for example, one course, the back body 32 and the rotational movement parts 42 and 43 are knitted (step). 6). When the joining of the rear sleeves 35 and 36 is advanced, the knitting width on the front needle bed side becomes insufficient. This is because the number of stitches in the back body 32 is larger than the number of stitches in the front body 31 due to the formation of the gussets 50 and 51. Therefore, both end portions of the back body 32 are moved to the front needle bed to be rotationally moving portions 45 and 46. This state is shown as step 6 'in FIG.

  When the joining of the rear sleeves 35 and 36 to the rotational movement parts 42 and 43 is completed, the both ends of the front body 31a and the rotational movement parts 42 and 43 are joined. The front body 31a and both ends 42, 43 are joined by gussets 50, 51 in step 2, but are not joined in the subsequent knitting operation. Therefore, the front body body 31a and both end portions 42 and 43 are joined to form, for example, a double eye, and the entire front body 31 and the back body 32 are knitted in an appropriate number of courses (step 7).

  FIG. 5 shows a modification of joining the sleeves. After the formation of the gussets 50 and 51 in step 2 in FIG. 3, the back body 32 is returned to the original knitting width. Therefore, the rear sleeves 35 and 36 are rotated and moved to the front needle bed (step 13). Next, when the front sleeves 33 and 34 are joined to the front body 31a and the knitting width of the front needle bed is reduced accordingly, the rear sleeves 35 and 36 are rotated to the front needle bed (step 14). The state where the joining of the front sleeve is completed is shown as step 14 '. Thereafter, Steps 6 and 7 in FIG. 3 are executed.

  As described above, in the embodiment, the knitting width of the back body 32 is reduced on the back needle bed, both ends of the front body are disposed on both sides of the back body, and left and right back sleeves are disposed on both sides thereof. At this time, on the front needle bed, left and right front sleeves are arranged on both sides of the front body body, and these are opposed to the rear body of the rear needle bed, both ends of the front body, and both rear sleeves. In order to create this state, it is essential to reduce the knitting width of the back body. If the front sleeve is joined to the front body body and the rear sleeve is joined to both ends of the front body, both sleeves can be joined to the inside of the body.

  FIG. 7 schematically shows an increase in the knitting width of the back body. Move the stitches on the back body one by one to the empty needles on the front body, rack the back needle bed, and transfer the stitches on the back body from the front needle bed to the back needle bed. Locked to the needle bed, the knitting width increases to the original knitting width. And it is good to perform the process of FIG. 7 by dividing into multiple times from the both ends of the back body to the center part, for example.

  Although the gussets 50 and 51 are formed in the embodiment, it is not always necessary to form them. In the embodiment, the left and right front sleeves 33 and 34 are joined to the front body 31a, and then the rear sleeves 35 and 36 are joined to the rotationally moving portions 42 and 43. However, these steps may be performed at the same time, and the rear sleeves 35 and 36 may be joined to the rotational movement parts 42 and 43 while the front sleeves 33 and 34 are joined to the front body 31a.

  In the embodiment, a two-bed flat knitting machine is used, but a four-bed flat knitting machine can be similarly knitted. When such an example is shown in FIG. 8, 71 and 72 are a lower needle bed, and 73 and 74 are an upper needle bed. First, the body bodies 31, 32, etc. are held on the lower needle beds 71, 72 without empty needles. In order to reduce the knitting width of the back body 32, the back body 32 is held by both the lower needle bed 72 and the upper needle bed 74. Here, instead of the upper needle beds 73 and 74, a stitch on the back body may be held using a transfer jack bed or the like. Furthermore, by using a compound needle having a hook and a tongue, by holding one eye with a hook and another eye with a tongue, one compound needle holds two stitches, The knitting width may be reduced.

The knitted fabric knitted in the embodiment is not limited to wear and can be used for various purposes.
