TECHNICAL FIELD The present invention relates to a method of forming knitting the knitted fabric using a flat knitting machine, to a method reducing inner forming the reduced line is gradually reduced in particular knitting width.

[0002]

2. Description of the Related Art When a knitted fabric is knitted using a flat knitting machine, the knitted fabric is moved to a desired shape by moving the stitches by transferring the stitches or swinging a needle bed to increase or decrease the knitting width. Can be organized. Such knitting is called forming knitting, and the loss at the time of cutting the knitted fabric can be eliminated, and the production cost of the knitted product can be reduced. The present invention relates to reducing knitting width, i.e. reducing knitting width, in forming knitting. There are two main methods of reduction, outside reduction and inside reduction. In the outside reduction, one stitch on the side end of the knitted fabric is moved inward by one stitch and overlapped with the inner stitch. In the inside reduction, for example, 4-7 on the side edge of the knitted fabric
The stitch group of the degree, that is, the stitch group at the side end is moved inward, and the innermost one or two stitches of the stitch group at the side end are overlapped with the stitch that has not been moved to form a stitch. With the outside reduction, the side edges of the knitted fabric tend to be jagged, and with the inside reduction, the side edges of the knitted fabric become smooth. For this reason, the inside reduction is superior to the outside reduction in the quality of the product after knitting.

[0003] In the inner reduction, an overlapping line is formed inside the knitted fabric side end, which becomes a so-called fashion line. For example, when the inside is reduced at the underarm part of the clothing parts such as the body and the sleeve, a fashion line is generated in this part. Then, after knitting, the stitches at the side ends of the parts are sewn together with a linking sewing machine or the like to produce clothing such as a sweater. Similarly, shrinkage is also used in the manufacture of sleeveless clothing such as vests. Inner reduction is performed in association with knitting of a knitted fabric, and is usually performed once every time a stitch row of about 2 to 4 courses is knitted. The number of stitches can be reduced by two at a maximum in one cycle, and if the number of stitches exceeds that, problems such as thread breakage are likely to occur.

FIGS. 4A and 4B show a knitting structure of a reduced portion of a knitted fabric 10 knitted by conventional inner reduction. Each rectangular portion indicates a group of stitches at the side end that moves due to reduction, and a small rectangle within a large rectangle indicates an individual stitch. Reference numeral 20 denotes a stitch in the case where six stitches are shifted and one stitch is reduced. In the knitted fabric 100, the number of stitches is shifted by six and the number of stitches is reduced by two. All are knitted fabric 10,
Every time two courses of 100 are formed, a reduction is made. As is clear from these figures, in FIG. 4A, the wale of the twelfth is reduced by the reduction of 10 times, and in FIG. 4-B, the wale of the twentieth is reduced by the reduction within 10 times. The number of courses knitted during this period is 20 in each case. By the way, since the second reduction is the upper limit in one reduction, the angle of the reduction lines L1 and L2 (the angle with respect to the stitch course other than the reduction portion, and the angle with respect to the horizontal direction in the figure) is as shown in FIG.
The case of b is the lower limit. This places constraints on the design of the forming knit.

In FIGS. 4A and 4B, the lengths of the reduction lines L1 and L2 are different, and the number of stitches required along the reduction lines is also different. Nevertheless, the number of courses of the stitches to be knitted during this period is the same with the conventional reduction in the number of stitches. On the contrary, the number of stitches along the reduction line is the same as the inside of the knitted fabric. For this reason, in the conventional knitted fabric knitted by inner reduction, the knitted fabric shrinks near the reduction line compared to other portions, and stitches are drawn from the inside of the knitted fabric to the reduced portion. Therefore, a desired reduction line cannot be obtained. This becomes more pronounced as the line decreases from FIG. 4-a to FIG. 4-b and the line becomes sharper. Such a knitted fabric is distorted and garments are likely to wrinkle.

[0006]

The basic object of the present invention is to reduce the angle at any angle with respect to the direction of the knitting width.
An object of the present invention is to provide an inner reduction method in which distortion does not occur in the reduction section.

[0007]

According to the present invention, a knitted fabric is formed by knitting a knitted fabric while forming a stitch group consisting of an appropriate number of stitches at a side end of the knitted fabric.
In <br/> Herashi method among using flat knitting machine for gradually reducing the knitted fabric knitting width by causing moved overlapped with stitches of the knitted fabric inwardly, a: the stitches of the knitted fabric end only for the group, the knitting of the next course
A step of organizing the eyes, b: relative stitch group wider range including the stitch group of the knitted fabric end, a step of knitting the stitches of the next courses, c: during the above a, b of step The knitting on the side end of the knitted fabric
The eye group is moved to the inside of the knitted fabric overlapped with stitches in the knitted fabric
And repeating the step of repeating the steps .

The stitch group on the side of the knitted fabric is 3 to 1
A stitch group consisting of 0 stitches .

Preferably, the number of the steps a and c and the number of the steps b are changed according to the shape of the knitted fabric, ie, the direction of the reduction line with respect to the direction of the knitting width.

Particularly preferably, the ratio of the number of steps a and c to the number of steps b is made substantially constant along a reducing line, that is, a line at the side of the knitted fabric at the portion where the reduction is performed. A straight reduction line is used.

More preferably, the number of steps a and c is determined on the basis of the length of the reduction line and the size of the stitch in a direction perpendicular to the stitch course at a portion where there is no reduction.

The operation of the present invention will be described. The stitch group to be moved along with the inner reduction is, for example, 3 to 10 at the knitted fabric side end,
Preferably, 4 to 7 stitches are moved. These stitches are called side stitch groups. Also, the line at the side of the knitted fabric at the portion where the reduction is performed is referred to as a reduction line. Further, a stitch group including the entire knitting width or at least a stitch group at the side end and having a wider range than the stitch group is a stitch group having a wider range than the stitch group at the side end. The course refers to a row of stitches in the direction of the knitting width, and particularly refers to a row of stitches knitted in one knitting. The pattern is a pattern in which the shape of the knitted fabric is specified on the design, and refers to literal pattern paper or data in which the shape of the knitted fabric is specified by a design device such as CAD. Since the object of the present invention is reduction, only the part to be reduced is considered unless otherwise specified.

If knitting is added only to an appropriate number of stitch groups at the side ends of the knitted fabric, the number of stitches increases along the reduced line compared to other portions. Since the stitch is moved in the reduction section, the stitch direction changes. For this reason, in order to prevent distortion in the knitted fabric, more stitches are required than in other portions. This stitch is supplemented by the knitting of the stitch group at the side end, and distortion of the knitted fabric can be prevented. The inner reduction itself is the stitch on the side edge
This is done by moving inside the group , preferably one movement per movement.
Move your eyes or two eyes. By adding the knitting of only the side stitch group , a stitch moving step, that is, a reduction step can be added, and the reduction can be performed at an arbitrary angle with respect to the direction of the knitting width. The reduction step is performed, for example, every time the additional knitting is performed for one or two courses.

Here, in order to prevent distortion of the knitted fabric,
It is necessary to determine the number of stitches along the reduction line. In the outside reduction, the moved stitch is elongated and distortion is unlikely to occur. In the inside reduction, the stitch group at the side end is reduced and the direction is parallel to the line,
The required number of stitches is determined by the length of the reduction line and the stitch size. The stitch size is, for example, the stitch size in the direction perpendicular to the stitch width when the stitch is in a natural state without any reduction. This size is the stitch size in the direction perpendicular to the stitch course at the portion where there is no reduction. Therefore, preferably, the number of stitches necessary for the reduction line is obtained using the length of the reduction line and the stitch size. This is the sum of the number of knitting of only the side end stitch group and the number of knitting in a wider range.

When the pattern is determined and the design of the knitted fabric is determined, the length of the line and the length of the knitted fabric at that portion are determined in consideration of the size of the stitch and the length of the knitted fabric at that portion is determined. The number of formations is determined. In addition, the sum of the number of times of knitting of only the side end stitch group and the number of times of knitting in a wider range is determined from the length of the reduction line. As a result, the number of times of knitting of the side end stitch group is determined. The width of reduction of the knitted fabric is determined from the pattern paper, which is determined by the number of movements of the side end stitch group and the number of movements per time. Therefore, a desired reduction line can be obtained by regularly repeating the three steps of knitting only the side stitch group, knitting in a wider range, and moving the side stitch group. For example, if the above three steps are reduced and evenly distributed along the line, a straight, uniform and clean reduction line is obtained.

As a result, in the present invention, the knitted fabric can be reduced at an arbitrary angle without causing any distortion in the knitted fabric, and hence without causing wrinkles when made into clothing or the like. Preferably, the number of knitting of only the side stitch group, the number of knitting in a wider range, and the number of movements of the side end stitch group are determined by the size of the pattern and the stitch. If there is a defect in the data determined in this way, the defect can be eliminated by finely modifying the design or the like. In this manner, the knitting procedure of the inner reduction unit can be easily determined. Furthermore, if the three processes of knitting of only the side stitch group (additional knitting), knitting in a wider range (normal knitting), and movement (reduction) of the side end stitch group are appropriately distributed, not only a straight line but also a desired one can be obtained. A line with a reduced shape can be obtained.

[0017]

FIG. 1 shows the design of the reduced portion in the pattern 1, the length of the line AB in the direction of the knitting width from the pattern 1,
The length of the line BC, which is the length of the knitted fabric at the reduction portion, and the length of the line AC of the reduction line 2 are known. A method of reducing the inner diameter when knitting with a predetermined stitch size according to the pattern 1 will be described below. The stitch size can be determined, for example, from the number of stitches in the x and y directions per 10 cm of the knitted fabric. For example, JP-A-7-1
As described in Japanese Patent No. 33562, a plurality of types of texture samples are knitted by changing the stitch size in advance, a sample having an optimum texture is selected, and the stitch size is determined. Then, the stitch size is applied to the size of the pattern 1 to determine the number of stitches.

The following data can be found from the dimensions of each part and the stitch size. The number of stitches to be reduced by reduction is determined from the length of the line AB, and this is determined by the number of reductions and whether one reduction or two reductions per reduction. The length of the knitted fabric of the line BC is determined by the number of times of normal knitting. The length of the line AC, that is, the length of the reduction line 2 is determined by the sum of the number of additional knitting and the number of normal knitting. In the vicinity of the reduction line 2, the stitch faces the direction of the reduction line 2, which is the direction of the stitch group at the side end. Therefore, the required number of stitches along the reduction line 2 for preventing the knitted fabric from being distorted is determined from the length of the line AC. The number of stitches can be obtained by dividing the length of the line AC by the size of the stitch, assuming that the stitch faces the direction of the line AC. The stitch size is determined from an optimal texture sample at the time of design, and is the size of the stitch in a direction perpendicular to the knitting width.
In an actual knitted fabric, this size is a stitch size in a direction perpendicular to a stitch course at a portion where no reduction is made. By subtracting the number of stitches required for line BC from the number of stitches required for line AC,
The number of additional formations is determined. In this way, the number of additional knitting, the number of regular knitting, and the number of reductions are determined. The number of stitches required along the line AC can also be obtained by the product of the number of stitches along the line BC and the length of the line AC and the length of the line BC. For example, if the length of the line AC is twice the length of the line BC, a double stitch along the line BC along the line AC is required. However, the knitted fabric has elasticity, and even if the number of stitches along the line AC is shifted by about ± 10% from the above value,
No significant distortion occurs along the line AC. The knitted fabric W is knitted so that the reduction line 2 is knitted regularly. For example, if the additional knitting and reduction and the normal knitting are equally distributed along the line 2 at the same ratio, a linear and regular reduction line 2 is obtained. Also, whether or not a knitted fabric according to the pattern is obtained depends on the stitch size. In the case of distribution of locations where additional knitting is performed or locations where reduction is performed, if there is an excess or deficiency in fractions or the like, the line BC or the line AB What is necessary is just to fine-tune the length. It is also possible to adjust whether one stitch or two stitches are reduced by one cut.

FIG. 2 shows that the length of the line 2 (the length of the line AC) is reduced at a ratio of 1: 3 with respect to the knitted fabric length (the length of the line BC) based on the stitch size and the pattern. The knitting block in the case is shown. In this example, every time the knitted fabric W is normally knitted twice, the knitted fabric group K at the side end of 5 wales is additionally knitted four times, and during that time, the first reduction is performed three times. Forming knitting with inner reduction is started from blocks 1 and 2 in FIG. 2, the knitting yarn is supplied to the needles a to r one round trip, and two stitches are knitted over the entire width of the knitted fabric W. The arrow of the block 3 indicates the direction of movement of the stitch, and the side ends 5 locked by the needles a to e of the front needle bed.
After the stitch group K is moved to the rear needle bed, the rear needle bed is shifted rightward by two needles, and is again moved to the needles c to g of the front needle bed. Thereby, the knitting width of the knitted fabric W is reduced by two stitches. Next, in blocks 4 and 5, one reciprocating knitting yarn is supplied to the needles c to g that lock the side stitch group K moved in the block 3 to knit two course stitches. In block 6, similarly to block 3, the stitch group K at the side end is moved to the rear needle bed, and then moved inside the knitted fabric for two stitches and moved to the needles ei of the front needle bed. . Thereby, the knitting width is further reduced by two stitches (P in R1). In subsequent blocks 7 to 9, the same knitting course as in blocks 4 to 5 is repeated, and the knitting width of the knitted fabric W is further increased by 2
Eyes decrease. In blocks 10 and 11, the knitting yarn is supplied to the needles g to r of the entire knitting width of the knitted fabric W in one reciprocating motion, and two stitches are knitted. Block 12 and subsequent steps correspond to the repetition of block 3 and subsequent steps. When the knitting cycle of R2 in the figure is repeated a required number of times, the inside is reduced and the line 2 can be reduced. In this manner, the regular knitting, the additional knitting and the reduction are regularly distributed. For this reason, the number of stitches along the reduction line 2 increases more than the number of stitches along the knitted fabric length (line BC), and at the same time, the knitting width decreases. For this reason, the distortion of the knitted fabric can be suppressed, and a knitted fabric having a shape close to the pattern can be obtained.

FIG. 3 shows a modification of the knitting cycle R3, in which the stitches are arranged along the line 2 (line AC) by reducing the knitted fabric length (line BC) by a ratio of 1: 2. Show. Every time the knitted fabric W is knitted for two courses, the stitch group K at the side end of 5 wales is knitted for two courses, during which the number of stitches is 3
Eyes decrease. In FIG. 2, the sub-cycle P is performed twice during the knitting cycle R1, but in FIG. 3, the knitting cycle P ′ equivalent to P is executed once. That is, the needles p to a in block 1
Is supplied, and the stitches of the knitted fabric W are knitted in one course. In the subsequent block 2, the stitch group K at the side end locked to the needles a to e of the front needle bed is moved to the rear needle bed, and thereafter, the rear needle bed is shifted rightward by one needle, and The stitch group K is transferred to the needles b to f of the front needle bed again. Thereby, the knitting width of the knitted fabric W is reduced by one stitch. Next, in blocks 3 and 4, the needles b to f for locking the stitch groups K at the side ends of the knitted fabric W moved in the previous block.
Is supplied to the knitting machine to form two course stitch courses. In block 5, after the stitch group K at the side end locked to the needle is moved to the rear needle bed, it is moved to the inside of the knitted fabric by one stitch and moved to the needles c to g of the front needle bed. Locked. For this reason, the knitting width is reduced by one stitch. In the subsequent block 6, only the inner reduction is performed, the stitch group K at the side end is moved to the needles d to h, and the knitting width is further reduced by one stitch. At block 7, the needle d for the entire knitting width
Ｐp are supplied, and the knitted fabric W is knitted for one course.

As can be seen from the above examples, the number of knitting and the number of reductions of only the side stitch group K are variously changed according to the angle of the reduction line. As the angle becomes acute, that is, the number of stitches to the knitted fabric length (line BC) (line A)
As B) increases, the number of additional knitting and reduction increases. In the present invention, when it is desired to sharply reduce the knitting width, the number of additional knittings is increased with respect to the number of normal knittings, and the number of reductions is accordingly increased. In this manner, reduction at an arbitrary angle can be performed.

In the embodiment, knitting for obtaining a linear reduction line has been described. However, the present invention can be applied even when the reduction line is a curve. In this case as well, the number of additional knitting and the number of reductions may be determined based on the shape and size of the curved portion, as in the embodiment. To get the knitting data,
Using AD, the pattern paper data including the dimensions of the knitted fabric to be knitted and the stitch size are quantified, and the length of the line AC with respect to the line BC is determined based on these numerical data. The number of reductions may be obtained. At this time, it is preferable that the pattern and the number of reductions can be automatically corrected in the CAD so that the knitted fabric to be knitted is similar to the pattern. In this way, the knitting data can be easily obtained.

[0023]

According to the inner reduction method of the present invention, it is possible to sharpen the angle of the reduction line by adding the knitting of the stitch course and the reduction knitting to the stitch group at the side end according to the shape of the reduction line, The restriction of the angle as in the related art is eliminated, and the knitted fabric can be formed and knitted into a desired shape.

Further, at this time, a required number of stitch courses are added to the stitch group at the side end of the reduced line, so that the length of the knitted fabric at that portion is extended, and the occurrence of distortion or the like of the knitted fabric can be suppressed. .

Further, the number of added knitting steps is reduced and evenly distributed to the lines, thereby preventing the appearance of the lines from being impaired.

Further, by reducing the required number of stitch courses in consideration of the stitch size and arranging the stitches in a line, a knitted fabric substantially in accordance with the pattern paper can be obtained, and the occurrence of wrinkles and the like can be prevented.
