DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a single circular knitting machine in which two knitting yarns are simultaneously supplied and one of the knitting yarns can be switched, and one surface of the single knitting yarn is switched with a different knitting yarn. The present invention relates to a method of knitting a knitted fabric of a knitted reversible structure.

[0002]

2. Description of the Related Art For example, a knitted fabric of a reversible structure, in which cotton yarn is exposed on one side and wool yarn is exposed on the other side, is generally widely knitted and used in terms of a heat retaining effect and a decorative effect. Further, the knitted fabric of the knitting structure is knitted while switching one surface with a plurality of yarns every several courses, thereby further improving the decorative effect and the like.

However, it is not possible to use a single circular knitting machine with a switching device for knitting while switching a plurality of yarns every several courses to knit a knitted fabric of a completely reversible structure such that the yarns on the front and back are completely different. It was possible.

In general, in order to knit a knitted fabric of a completely reversible structure, separate yarns (a surface knitting yarn and a backing knitting yarn) are always fed from a different direction to a different position in a hook of a needle without change. It is necessary to drill two relatively small diameter through holes for the yarn path at different angles at different positions of the yarn guide, and use this guide to prevent the yarn from oscillating while keeping the needle hook in the hook. Generally, yarn is always supplied to different positions without fluctuation. The reason why the yarn is fed into the needle hook from different directions is that the yarn does not come into contact even when the yarn is fed due to a change in the yarn path. But a guide is needed.

Furthermore, when using the above-mentioned single circular knitting machine with a switching device, it is necessary to switch one of the knitting yarns, and in each case, insert the switched yarn into the through hole for the yarn path of the yarn guide. Therefore, a V-shaped groove is formed on the outer surface of the yarn guide in place of one of the through holes, and the V-shaped groove is guided so as to be in sliding contact with the bottom of the groove and supplied into the needle hook at a predetermined position and angle. It is common to thread.

[0006]

However, when the yarn is supplied along the V-shaped groove, the knitting yarn is simply slid in contact with the V-shaped groove and supplied. Since there is less restriction on the swing of the yarn as compared with the above, it is impossible to feed the yarn in a desired direction in a desired position without a change in a yarn path in a narrow hook, and a complete reversible structure is required. It was impossible to knit the knitted fabric.

In view of the above situation, the present invention provides a completely reversible knitted fabric by feeding different yarns (a surface knitting yarn and a backing knitting yarn) at different positions in a hook of a needle without change. It is intended for knitting.

[0008]

According to the knitting method for a reversible structure of a circular knitting machine with a switching device of the present invention, two knitting yarns are simultaneously supplied and one knitting yarn is supplied to achieve the above object. In a single circular knitting machine with a switching device that is switchable, the switchable knitting yarn is fed into the hook of the latch needle, and the other thread is outside the hook of the latch needle, and when the latch of the latch needle is closed and rotated. And knitting by feeding yarn to a position where it is pushed into the hook in contact with the yarn.

[0009]

According to the present invention, of the two knitting yarns supplied to the single circular knitting machine, the switchable knitting yarn is fed into the hook of the knurled needle. On the other hand, the other yarn is supplied to a position outside the hook of the latch needle, which is brought into contact with the latch and pushed into the hook when the latch of the latch needle is closed and rotated. Without being reversed, the other thread is always pushed from below into a fixed position in the left corner of the hook. For this reason,
Since the relative position of the latch needle in the hook does not always fluctuate, a knitted fabric with a completely reversible structure can be obtained.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. In the drawing, reference numeral 1 denotes a yarn guide, and a V-shaped groove 2 is formed in the yarn guide 1, and a surface material knitting yarn 3 is slidable in this groove 2 in a pressed state. For this reason, the outer knitting yarn 3 is guided along the bottom of the groove 2 and supplied to the innermost portion A of the hook 5 of the latch needle 4. After the desired knitting of the outer knitting yarn 3 is completed, the yarn is switched by a known switching device and guided by the groove 2 of the yarn guide 1, so that the yarn may slightly fluctuate. Considering this, the yarn may be supplied to a position from the center of the hook 5 of the spatula needle 4.

A yarn insertion pipe 6 is fixed to a side edge of the yarn guide 1, and a lining knitting yarn 7 is inserted through the insertion pipe 6. The position of the lower end of the pipe 6 is set to a specific position. That is, the lower end of the pipe 6 can be supplied outside the hook 5 of the latch needle 4 to a position B which is brought into contact with the latch 8 and pushed into the hook 5 when the latch 8 of the latch needle 4 is closed and rotated. Is set. In this manner, the outer knitting yarn 3 and the backing knitting yarn 7 are separately supplied and knitted, and a knitted fabric having a completely reversible structure can be knitted. The thread insertion pipe 6 is preferably made of friction-resistant titanium or fiber reinforced plastic or the like, and its inner diameter is preferably 0.5 to 1.0 mm. Note that, instead of the pipe 6, the shape of the yarn guide 3 may be increased to provide a through hole at a desired position. As a modified application of the knitted fabric of the reversible structure, by using an elastic yarn for the knitting yarn, a reversible stretch fabric can be obtained by using a switching machine.

[0012]

As is apparent from the above description, according to the present invention, two knitting yarns supplied to a single circular knitting machine are supplied into the hooks of the latch needles relatively constantly without fluctuation. Therefore, it is possible to provide a knitting method of a reversible structure that can obtain a knitted fabric of a complete reversible structure even when one of the two knitting yarns can be switched.
