Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for forming an opening in a portion of a bag knitted fabric knitted by a flat knitting machine.

[Prior art]

According to a flat knitting machine having front and rear needle beds, bag knitting can be performed by causing the knitting needles on either the front or rear needle beds to perform a knitting action in the forward course, and by causing the knitting needles on the other needle bed to perform a knitting action in the backward course. Work gloves, socks with toe pockets, and the like are made using this method.

By the way, as shown in Figures 10 and 11, this glove has holes 3 at appropriate locations in the finger pockets 2 of the glove 1, which makes it convenient to insert and remove only the fingers. As shown, holes 4 are formed in the folded part 1a of the wrist knitted fabric or the palm part 1b.
Alternatively, if 5 is left open, it is convenient to provide a pocket 6 with that opening as the opening. In addition,
Reference numeral 7 denotes a lid that covers the hole 5, which is the opening of the pocket 6.

Further, as shown in FIG. 12, holes 9 and 9' for inserting and removing the hands are made in the gloves 8 and 8', which are knitted long at the wrist, respectively.
8' are sewn together and connected 10 to form a glove muffler 11 that can be used both as a muffler and as gloves.

However, in the prior art, openings 3, 4, 5, 9, 9' as described above are formed only by the knitting structure in a part of such a bag knitted fabric knitted by a flat knitting machine. It was not easy to form it.

This is because, in order to form an opening in a part of the bag knitted fabric, if an arbitrary number of consecutive stitches in the course direction are removed from the knitting needles during knitting of the bag knitted fabric using a flat knitting machine, the knitting needles It is necessary to perform a process to prevent the stitches removed from unraveling.Next, in order to create the stitches for the set-up course of the opening, the stitches of the bag-knitted fabric are placed on the knitting needles on the opposite needle bed. Because the knitting needles are so dry that I can't use them,
This is because there was no other choice but to create the stitches of this set-up course by hand.

Therefore, as a conventional method, for example,
A method such as that seen in Publication No. 59-71402 has been proposed. That is, it is proposed that after the glove is manufactured, the fingers and palm surfaces are incised to form an opening, and the cut is overstitched or impregnated with resin to allow the knitting yarn to be formed. It has been proposed to prevent it from unraveling from the cut end.

[Problem that the invention seeks to solve]

However, with the conventional method described above, it takes a lot of work to form openings at desired locations in the bag knitted fabric, or else the openings cannot be finished neatly. With drawbacks.

In this invention, by knitting a bag knitted fabric including an opening using a knitting method different from the conventional method, the opening can be easily formed and a beautiful opening can be obtained. The present invention aims to provide a method for forming an opening in a part of a bag knitted fabric.

[Means to solve the problem]

That is, in order to solve the above-mentioned problem and form an opening in a part of a bag knitted fabric, when knitting a bag knitted fabric by a flat knitting machine, in the middle of knitting, the bag knitted fabric is continuously knitted in the course direction. After discarding any number of courses on a series of arbitrary number of stitches, remove the last course of the discarded stitches from the knitting needles, and then first knit the discarded fabric for each course. Raise any two or every third knitting needles among the knitting needles that have been removed to the working position, feed the knitting yarn of the set-up part to these knitting needles by turning over the required number of courses, and perform the knitting operation on these knitting needles. By giving this, the set-up part is made to form a set-up part stitch in which at least two or more gaps are discontinuous in the course direction, and then the knitted fabric of the next course and subsequent courses is knitted, and then the knitted fabric is knitted again. Provide bag making.

[Effect]

The method of the present invention is a method in which openings are formed as a knitting structure at desired locations in the bag knitted fabric during the knitting process of the bag knitted fabric. An arbitrary number of series of stitches are removed from the knitting needles, but in the method of the present invention, an arbitrary number of waste stitches are performed before the stitches are removed from the knitting needles, so that the end of the stitch forming the opening is By appropriately selecting the course knitting yarn, it is possible to prevent the yarn from unraveling easily.

Furthermore, in the method of the present invention, in order to be able to knit a bag knitted fabric following the opening, the stitches of the set-up portion of the opening are formed using knitting needles from which the loose knitted fabric has been removed. , the method of forming the stitches is to raise every second or third arbitrary knitting needle among the knitting needles from which the waste knitted fabric was previously removed to the working position, and apply the set-up part to these knitting needles for each course. By folding and feeding the required number of courses of knitting yarn and giving a knitting action to these knitting needles, first, a stitch of a set-up part in which at least two or more gaps are not continuous in the course direction is formed in the set-up part. Since this is a method of knitting the fabric from the next course onward, each stitch of the next course formed in the set-up part in this way has its sinker loop connected to the knitting of the previous course. It is knitted in such a way that the threads also penetrate in the course direction.

Therefore, the opening edge on the knitting start side of the opening formed according to the method of the present invention is mechanically knitted into a knitting structure that will not unravel.

Example 1 The opening ₃ as shown in Figs.
When the nth course is reached, it is temporarily interrupted and the 9th stitches L ₁ , L ₂ ...L ₈ , which are continuous in the course direction
Feed the knitting yarn y ₂ for waste knitting only to the knitting needles N ₁ , N ₂ , ... N ₈ , N ₉ on which L ₉ is attached, and perform 2 courses (1 round trip course) of waste knits 12 and 13. Furthermore, when the stitches of the final course 13 of the waste knitting are removed from the knitting needles _N1 to _N9 , the knitted structure on the knitting end side is obtained.

Next, when knitting the set-up part of the opening, first, among the knitting needles N ₁ to _{N 9} from which the stitches have been removed,
Raise every second knitting needle N ₂ , N ₅ , N ₈ to the working position, and continue to feed the knitting yarn y ₂ used for knitting the waste stitches to these knitting needles N ₂ , N ₅ , N ₈ through this opening. After feeding the yarn as a knitting yarn to the set-up part of the section and knitting the first course 14, in the next second course 15, the other knitting needles N ₁ to N ₉ from which the stitches were previously removed are used. Every second knitting needle N ₉ , N ₆ , N ₃ and the knitting needle at the end of this course
Raise N ₁ to the working position and connect these knitting needles N ₉ , N ₆ ,
When the knitting yarn y ₂ is fed to N ₃ , N ₁ and a knitting operation is given to these knitting needles, the knitting needles N ₁ , N ₂ , N ₃ , N ₅ ,
By N ₆ , N ₈ , and N ₉ , the stitches are knitting needles N ₄ and N ₇
Setup stitches that are missing only at certain positions, that is, stitches L′ ₁ , L′ ₂ , L′ ₃ , L′ ₅ , L′ ₆ , in the setup portion where two or more breaks are not continuous in the course direction, L' ₈ ,
L′ ₉ is formed.

After that, it goes without saying that by raising the full-knitting needle on which the stitches are being applied to the working position, it is possible to restart the bag knitting of the next course (n+1) or less, and in the case of this example, the next course with knitting yarn y ₁ can be resumed. (n+
By knitting 1), the set-up stitches of all the wales in the part of the bag knitted fabric in the opening 3 are completed for the first time, and the sinker loop of this course (n+1) is knitted in the previous courses 14 and 15. It is pierced and secured by thread y ₂ .

Example 2 In the above example, in the bag knitting course (n+1) using knitting yarn y ₁ , the set-up stitches of all the wales of the bag knitted fabric portion in the opening 3 were completed, but in other examples , when knitting the set-up portion of the opening, the first and second courses 14,
After organizing 15 courses, the next 3rd and 4th courses 16,
17 may be organized as shown in FIG. In other words, knitting is continued with knitting yarn y ₂ ,
During this time, the set-up stitches of all the wales for the bag knitted fabric in the opening 3 may be completed.

In the embodiment shown in FIG. 2, the third course 1
6 stitches L' ₁ , L' ₄ , L' ₇ are transferred to every other two remaining knitting needles N ₁ of the previously removed knitting needles N ₁ to N ₉ ,
It is formed by feeding knitting yarn y ₂ to N ₄ and N ₇ , but in this case as well, the sinker loop formed by the next fourth course 17 is the same as that of the previous one. It is prevented from unraveling by being penetrated by the knitting yarn _y2 of courses 14, 15, and 16.

In addition, in this embodiment, at the turn-around section where the third course 16 of the set-up section transitions to the fourth course 17,
The knitting yarn y ₂ is also fed to the knitting needle N ₁₀ on which the right phosphorous bag knitted fabric of the knitting needle N ₉ is applied, and the knitting operation is also given to the knitting needle N ₁₀ , thereby knitting the knitting needles N ₁ to _{N 9} . Therefore, when obtaining the stitches for the set-up part of the bag knitted fabric in the opening 3, the stitches by knitting y ₂ are placed on the right side of the knitting needle N ₁₀ .
L′ ₁₀ is formed.

Embodiment 3 In the above embodiment, only in the turning section where the third course 16 of the set-up section transitions to the fourth course 17,
The knitting yarn y ₂ was fed to the knitting needle N ₁₀ on which the right phosphorus bag knitted fabric of the knitting needle N ₉ was placed, but in other embodiments, as shown in FIG. 1st

Embodiment 7 FIG. 6 shows yet another embodiment. This embodiment is different from the fifth embodiment described above.
In this embodiment, the knitting yarn y ₂ fed to the knitting needles N ₀ and N ₁₀ in the set-up courses 14 and 15 is knitted in the same manner as in the third embodiment, thereby forming the set-up stitch L' ₁
Although stitches L' ₀ and L' ₁₀ were formed on both sides of ~L' ₉ , in this seventh embodiment, the knitting yarn y ₂ fed to the knitting needles N ₀ and N ₁₀ was used in the fourth embodiment. Similarly, in the case of , it is at the point where the tasks T ₀ and T ₁₀ are made.

Example 8 In the above example, an example in which the loosely knitted fabric is knitted in only two courses is illustrated, but in other examples, as shown in FIG. If the coarse knitted fabric is knitted, the loosely knitted fabric remains in the form of a flap at the edge of the opening 3 formed by the method of the present invention.
It can be a lid 7 for the opening 5 as shown in FIG.

Example 9 In each of the above examples, an example was shown in which the waste knit fabric and the set-up stitch of the opening were knitted with one continuous knitting yarn _y2 , but in other examples, the waste knit It goes without saying that the set-up stitches for the base and opening may be knitted using different, non-continuous knitting yarns _y2 and _y3 (see Figure 8).Example 10 Figures 1 to 7 In each of the examples shown, after removing the stitches of the final course 13 of waste knitting from knitting needles N ₁ to N ₉ ,
Immediately, the knitting of the set-up course 14 at the opening was started, but in other embodiments, as shown in FIG _.
~ After removing from N ₉ , knitting yarn y ₁ knits the bag knitted fabric on the knitting needles on which the bag knitted fabric is still applied, without immediately moving to knitting of the opening set-up course 14.
, an arbitrary number of courses 2 with the opening 9 as the turning point
1, 22, 23, 24, 25 may be turned over and fed to form a plain knitted fabric of an arbitrary length continuing on the bag knitted fabric in the wale direction on both sides of the opening 9.

Such openings 9 are suitable as the holes 9, 9' of the glove muffler 11 shown in FIG.

Example 11 FIG. 9 shows the knitting structure of the opening obtained by another example. This example is the first to
The difference from the embodiment shown in FIG. 8 is that when the set-up portion of the opening is knitted, the first to fourth courses

N ₁ (2nd course 15), N ₄ , N ₈ (3rd course 16)
By feeding the yarn to N ₉ , N ₇ , N ₃ , N ₁ (fourth course 17) and giving a knitting operation to each course, the knitting yarn y ₂ of the four courses 14 to 17 in the set-up section is Then,
The point is that set-up stitches of all wales for the bag knitted fabric in the opening 3 are obtained. In addition, in the case of this example, the sinker loop of the next course (n+1) of knitting yarn y ₁ is the sinker loop of the previous course 14 to 1.
By being penetrated by knitting yarn y ₂ of No. 7,
It will be unraveled.

Example 12 In Examples 1 to 10 above, when knitting the set-up part of the opening, the knitting yarn y ₂ was used in the first to fourth courses 14 to
In 17, the yarn was always fed to every second knitting needle, and in the above-mentioned Example 11, the yarn was always fed to every third knitting needle, but in other examples, the yarn was fed to every second knitting needle in the above-mentioned 1st to 4th courses 14 to 17. In addition, the knitting yarn y2 may be fed every second yarn or every third yarn at different intervals, and in another embodiment, the knitting yarn _y2 may be fed every second yarn or every third yarn in one course. The knitting yarn _y2 may be fed at different intervals (not shown).

[Other Examples]

In addition, as shown in FIGS. 1 to 6 and 8 to 9, if there are several courses or less, all of the waste courses 12 and 13 correspond to this, but the above By knitting several courses of each of the loosely knitted fabrics, including the courses that will become the edge portions, with a knitting yarn mixed with a low melting point thermoadhesive yarn, the knitted fabric can be formed by the method of the present invention. By heat-treating the knitting end edge of the knitted fabric at the opening section after removing it from the knitting needles, it can be prevented from unraveling, and every other knitting needle is attached to the set-up section of the opening sections 3 and 9. If the fed knitting yarn is knitted with a knitting yarn mixed with stretchable elastic yarn that is stretchable at room temperature, such as woolly nylon spandex or rubber yarn, the knitting yarn can be formed by the method of the present invention. The set-up stitches of the openings 3 and 9 can be easily tightened.

That is, as in the embodiment described with reference to FIGS. 1 to 9 above, the loose knitted fabric and the stitches in the set-up portions of the openings 3 and 9 were knitted with knitting yarn y ₂ or y ₂ , y ₃ . In this case, if this part is knitted with a knitting yarn that is a mixture of a low-melting point heat-adhesive yarn and a stretchable elastic yarn that is stretchable at room temperature, the openings 3 and 9 can be formed by heat treatment. The edges of the waste stitches have an anti-unraveling effect,
In the set-up portions of the openings 3 and 9, a tightening effect of the set-up stitches can be obtained.

An example of a low melting point thermoadhesive yarn for obtaining the above effects includes, for example, the low melting point thermoadhesive fiber "Toray Elder Yarn" (trade name) manufactured by Toray Industries, Inc.

〔effect〕

According to the method of the present invention, the stitches on the set-up side of the opening are knitted into a knitting structure that is prevented from unraveling from the beginning only by mechanical operation without manual operation, and is therefore compared to conventional methods. Therefore, openings can be formed very efficiently. The knitting end side of the opening requires treatment to prevent unraveling, but since this part has been knitted, several courses, including the course that will become the edge, are sewn by a sewing machine or processed with a low melting point. By knitting with knitting yarn mixed with heat-adhesive yarn, etc., it is possible to easily prevent unraveling.

Therefore, according to the method of the present invention, an opening can be formed in a part of the bag knitted fabric with fewer steps overall, but the openings formed according to the method of the present invention can be The opening edge on the side of the set-up course is made up of only knitted fabric and is very clean, so the method of this invention can be used not only for gloves and glove mufflers mentioned at the beginning, but also for socks and other flat knitting machines. Therefore, it can be used to form an opening in a part of any bag-knitted product that can be knitted, increasing its commercial value.
