Abstract

PROBLEM TO BE SOLVED: To provide a guide for feeding yarns capable of accurately feeding the yarns without mutually turning over the yarns of different kinds when doubling the plural kinds of the yarns of different kinds and feeding the yarns to a circular knitting machine. SOLUTION: A yarn guide piece 8 in a recessed shape is arranged near a cutting off part 6 in a guide 1 for feeding a yarn obtained by installing a yarn feed port 2 at a site in a lower part of the guide 1 in a rectangular shape for feeding the yarn and further providing the cutting off part 6 in a circular arc shape at a site in a lower part of the guide 1. Thereby, there is no fear of slipping off of the yarn guided by the guide piece 8 from the guide piece 8 in the recessed shape even when vibrated in the vertical, left and right directions under an abnormal tension. As a result, the positions for feeding yarns of different kinds are not mutually turned over when feeding the yarns of the different kinds to the side of a knitting needle 30. An abnormal knitting defect is not caused and a knitted fabric good in quality can efficiently be produced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn feeder for supplying a plurality of different kinds of yarns to a circular knitting machine so that the different kinds of yarns can be supplied accurately without being inverted. About the guide.

[0002]

2. Description of the Related Art Conventionally, when two or three different kinds of yarns are aligned and fed in a knitting circular knitting machine, for example, as shown in FIG. In knitting the knitted fabric by feeding the yarn to the knitting needle 30 side such as a needle, the yarn 20 such as cotton thread is inserted into the yarn feeder 52 and the yarn 21 such as polyurethane elastic fiber with high elasticity is fed. The yarn is fed to the knitting needle 30 through the cutout portion 56 provided at the lower part on the front side of the guide 50.

[0003]

As described above, when the yarn 21 passes through the cutout portion 56 of the yarn feeding guide 50, the yarn 21 may be moved in the vertical and horizontal directions due to, for example, abnormal tension fluctuation. When the thread 21 vibrates in the direction
6 and moved to the lower part on the opposite back side,
The yarn 21, which is displaced, passes through the back side of the yarn feeding guide 50 and is fed to the knitting needle 30 side.

Accordingly, as shown in FIG. 4, a yarn 20 to be knitted and positioned on the surface side of the knitted fabric is positioned on the back side of the dough as shown in FIG. The yarn 21 to be positioned is located on the surface side of the fabric, and this has caused abnormal occurrence of abnormal knitting flaws.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a yarn feeding port 2 in a lower portion of a rectangular yarn feeding guide 1 and a circular hole in a lower portion of the guide 1. In the configuration in which the arc-shaped cut portion 6 is provided, the concave thread guide piece 8 is provided in the vicinity of the cut portion 6, so that the thread guided by the guide piece 8 is vertically moved by abnormal tension. Even if the yarn is vibrated in the left-right direction, there is no danger that the yarn will come off from the concave guide piece 8, and therefore, when the different kinds of yarn are fed to the knitting needle 30, the yarn feeding positions are not reversed with each other. It is possible to efficiently produce knitted fabrics of good quality without generation.

[0006]

1 and 2, reference numeral 1 denotes a yarn feeding guide of a circular knitting machine, and reference numeral 2 denotes a yarn feeding port provided at a lower portion of the guide 1 so that a yarn 20 such as cotton thread can be inserted therethrough. Reference numeral 5 denotes a protrusion integrally provided below the thread guide 1, reference numeral 6 denotes a cutout portion cut out in an arc shape at a lower portion on the front side of the protrusion 5, and reference numeral 8 denotes a cutout of the cutout portion 6. A thread-shaped concave guide piece fixedly provided in the vicinity guides a yarn 21 made of highly elastic polyurethane-based elastic fiber through the guide piece 8.

[0007] Reference numeral 10 denotes an elongated hole provided above the yarn feeding guide 1, which is adapted to appropriately fix the guide 1 to the circular knitting machine via a screw piece 11, and 15 denotes a guide for the yarn 21. It is rotatably provided on the side of the yarn feeding guide 1 as needed.

In the present invention, since the yarn 21 is guided to the knitting needle 30 such as the lower needle through the concave guide piece 8 as described above, even if the yarn 21 vibrates vertically due to abnormal tension. The yarn is reliably supplied to the knitting needle 30 without coming off from the concave guide piece 8. The present invention is also applicable to a milling circular knitting machine including a lower needle and an upper needle.

[0009]

According to the present invention, as described above, the yarn feeder 2 is provided below the rectangular yarn feeding guide 1, and the arc-shaped cutout 6 is provided below the guide 1. By providing the concave thread guide piece 8 in the vicinity of the cutout section 6, the thread guided by the guide piece 8 can be concavely guided by the abnormal tension even if it vibrates vertically and horizontally.
It does not come off.

That is, when two kinds of yarns are fed to the knitting needle 30, for example, as in the prior art, the yarn feeding positions are not reversed with each other, so that abnormal knitting flaws do not occur and the quality is good. It is possible to efficiently produce natural knitted dough.
