Abstract

1. A device for storing filamentary material e.g. weft yarn, wire, tape etc., it, weaving machines, comprising a substantially cylindrical former (6) for forming the package and a material feed passage (8), one of the said two parts, i.e. the former (6) and the material feed channel (8), being constructed to rotate relatively to the other part, characterized by at least one hook-shaped recess (12) disposed at that end (30) of the former (6) which faces the material feed passage (8), for returning to the former (6) a material run (10) which has incorrectly been wound behind said end (30) of the former.

The invention relates to textile machinery and relates to devices for collecting thread-like material on a loom.

The purpose of the invention is to increase the reliability of the device by returning the filament material descended from it to the body.

FIG. 1 shows the proposed device; in fig. 2-6 - the same, in different positions; in fig. 7 - the second form of the device; in fig. 8 - the same, axonometrics; in fig. 9 - schematic implementation of the excavation.

The device contains SFig. 1-6) disk t, fixed on axis 2. On disk 1, the winding body 3 is fixed with axis 4. Axes 2 and 4 do not coincide with each other. On the winding body 3 and the disk, the bows 5 are fixed. Onch together with the winding body 3 form a surface 6 on which a thread of the pattern is removed. If the material 9 is removed, the first package of turns coils and part of the thread-like material is behind the disk, then

ny material. In the direction of arrow 7, the 25th part rotates is automatically pulled out and

The yarn guide 8 which winds the yarn-like material 9 onto the surface 6. The yarn guide 8 rotates between the disk I and the clapper 10 (Fig. 3). The coils 9a of the thread-like material are placed between two shafts 11, moving along arrow 12 and as they are released, the thread-like material for rolling into the base of the warp along arrow 13. On the disk 1 there is a notch 14, which is hook-shaped and positioned so that the top of the notch is always directed towards the reeled threadlike material. The notch 14 contains the internal profile 15 and the top 16 formed by the intersection of the profiles 15 and 17. On the disk

1 there may be three recesses 14, 14a and 4b (Fig. 1). The outwardly formed recess 14 ends with a tip 18 directed upward and towards the material being wound.

In the device of FIG. 8 and 9 on the axis

2 secured the drum 19, which is wound material 9 with a conical expansion 20, where the groove 14 is made. The tip 18 can be bent upwards.

The device works in the following way.

When the thread-like material 9 is broken, the yarn guide 8 (Fig. 2) should rotate in the opposite direction of the arrow 7. At the same time, he is in position 8a

and after this position 8b (fig.Z). This position is taken as the initial one after the thread interruption

of material 9 has been eliminated. In this case, the material 9 forms a loop 9b and when the yarn guide 8 is rotated according to arrow 7, a significant loop 9c is formed (Fig. 4).

When the yarn guide 8 is in position 8d (Fig. 5), a branch of the thread-like material 9d (indicated by strokes) may be behind the disk 1. With the subsequent rotation of the thread guide 8, the thread-like material 9 in section 9f (Fig. 6) is caught by the notch 14 and thereby returns to surface 6. The operation of the device is no different from the usual

mode.

If, after the elimination of the breakage of the material 9, the first pack of turns shrinks and a part of the threadlike material is behind the disc, then this

the part is automatically pulled out and

this eliminates winding on axis 2.

If the thread-like material 9 falls behind the disk 1 during the operation of the loom and the storage device, the thread-like material 9 returns to the surface 6 when the thread guide 8 passes over the recess 14.

The proposed device allows to increase the reliability of the weaving machine.

Claims (2)

1. Device for accumulating threadlike material on a loom, containing a cylindrical winding body with conical expansion at the beginning of winding the threadlike material and feeding thread, as well as a means for preventing thread winding from the cylindrical winding body installed with rotation; , with the fact that, in order to increase the reliability of the device by returning the thread-like material to the winding body from it, The water turns of the threadlike material is made in the form of at least one notch having a hook shape and located in a conical expansion of the winding body, with the top of the notch being in the form The hook is always directed towards the threadlike material that is wound on the winding body. 2. The device according to claim 1, characterized in that it is found 14438084 The forming hook-shaped recesses are directed upwards with their tips relative to the longitudinal axis of the cylindrical winding body and towards the winding thread-like material. five Fig lit FIG L ft 1b 9d fPug.S FIG. 6 M id Fig l 9
