DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a yarn feeding device as set forth in claim 1.

Known yarn feeding device of this type (Swiss special π), Publication No. 64
1.1.19), the raised surface (chest) of the thread groove is formed by each spindle,
These spindles are each arranged in the spacing η' between the two polygonal rods in such a way that the bottom of the thread groove corresponds to the formation of the polygonal rods.

The fed yarn is thus held on the one hand by the polygonal bar and on the other hand by the bottom of the respective thread groove and deflected into the corners of the polygon. In such a configuration, the yarn is tension-balanced at high speed for the purpose of passing it through the yarn feeder near the yarn feeder, for example, the yarn heddle of a loom.

It should be used for the purpose.

A111 Therefore, the circumference of the second (1) part where the thread body is delivered is (-1, the first part, i.e. At the bottom of the groove, t at l knee)
This is because the circumference of the first part, which is additionally forced to the circumference formed by each of the I-shaped pieces, is shorter than the circumference of the first part. If the circumferential length of the first part is equal to the circumferential length of the second part (1), in each case there is a significant difference in the circumferential length of the first part, when the spool body is formed on the other side of the spool body from the first part. It would be impossible for the ship 11 to be handed over to part 1- in the 11th station, which maintained the station 11, and to be transferred from the rear to the front station. (-nuyo (i

bow). In the case of a yarn feeding device of L type, the yarn △, -Ti- on the second part of the body are arranged in an orderly manner L,
The alignment is achieved by sliding the polygonal bar, which is attached to the thread, up to the front end so that it is sufficiently inclined.

That is, in this arrangement, the shape of the polygonal bar on the second part has a truncated conical shape L7, so that the excessive length of each pincushion body relative to the circumferential length of the polygonal bar increases significantly. It is achieved by being [2.This, however, makes it difficult to use this type of yarn feeding device, e.g. in order to subject the yarn to certain subsequent treatments, e.g. to steam-treat the yarn. Use a barrier to place it in place. Furthermore, the bearings, arrangement and drive of the spindles, which are arranged between two polygonal rods, are very expensive and also a construction that is prone to failure. In this case, it is also not possible to draw the thread body still present on the first part into the prepared thread store.

The yarn is passed through the head of a circular knitting machine, for example. A central cylindrical thread body is provided, and this screw 1
11 The body is rotatably bearing on the outside and is provided with a f (-1) shaped body. The transfer 7 of the first part to the second part L' and L' takes place. That is, the storage capacity achieved is relatively small, and at L' and The use of the device requires only a relatively short length of thread to be drawn from the IF.
- Limited to use for machines for 11.

An object of the present invention is to provide a yarn feeding device of the above type with a simple structure and operational reliability, while maintaining a constant yarn tension and a relatively large amount of yarn storage so that yarn can be pulled out. - It is to configure it so that there is no preparation [, advantage Z).

This problem is solved by the features recited in claim 1.

Other advantageous configurations of the present invention are described in claims 2 to 6r.

This configuration ensures reliability in use and requires relatively little cost. ) structure is not achieved.
It is possible to form a yarn feeding device for a consuming machine 44, such as a loom (1), where the yarn tension is constant. (1) Essentially, the thread body is pulled from the first part by the first γ<1!min・\ g6 while maintaining the orderly [7/hi arrangement of the winding, and then the thread body is This is achieved by the impacting action of the last breast against the first part of the first part, and by the fact that they are brought into close contact with each other and sent into a parallel 12' state. The periphery J between the first part and the second part Pre-array is performed in region-1 of the first part, and this child (4!i array is extracted from i-+1).
However, in the first part-1 of the first part, the thread winding bodies are juxtaposed closer together than in the first part. The amount of storage to be prepared and the spool body guided on the first part and present in the red screw groove are also provided in the drawer, and as long as f is 4! = Become. 1'A- This device is constructed from 91J and others.

Finally, on the outer surface of the polygonal rod, a sliding step for the yarn is cut NH3 at half the length of the circle 1iTh. This sliding step makes it possible to achieve a tension balance to a certain degree, which is especially true for yarns with a particular elasticity.Furthermore, the loading of the yarn in the area of the yarn feeding position can be The end of the square rod starts from a ring, which is conveniently carried out by a ring which forms a truncated, conical sliding surface in the yarn feeding plane.The yarn is passed from the thread eye to This sliding face is reached.The thread then passes by the end face of this ring.The end of the thread is seen in the area of the thread feeding position (located approximately in line with the chest section at I-17. The thread is reliably placed in the initial region of the thread groove.
