SU1359366A1 - Device for feeding weft to gripping shuttle of multicolour loom - Google Patents

Abstract

The invention relates to textile machinery and allows for an increase in the speed capabilities of the machine. The holders are moved to the feed position of the weft yarn to the clamping hook by means of the slider 7, then rotate the sector 5 to the next feed position of the weft yarn. The twisting of the rotary sector 5 begins until the end of the movement of the holder, the angle of rotation of which is determined by the contact of the tooth 8 of the slider 7 with the slot of the holder.

Description

The invention relates to textile engineering and is intended for use when changing the color of the weft yarns on weaving machines with a clamping hook.

The purpose of the invention is to increase the speed capabilities of the machine.

Figure 1 presents the feeder weft threads to the clamping shuttle multicolor loom, top view; figure 2 is the same, side view; on fig.Z - section aa in figure 2.

A feeder for feeding the weft yarns to the clamping hook (not shown) with steel wire 1, the number of which is equal to the number of replaceable weft yarns. The holders 1 have nodal grooves 2 and 3 and are placed in the guides 4 of the rotary sector 5 connected with the mechanism for forming the weft pattern of the machine (not shown). In the guide 6 there is a slider 7, having a tooth 8 entering the groove 2 holder 1. Niter holders 1 in the guides 4 are fixed by means of plate springs 9- fixed on the turning sector 5, the lamellar springs 9-, the protrusions 10 of which are included in clauses 3 of the three holders. Prongs 9 are provided with protrusions 11 for engaging with roller 12,

The rotary sector 5 has an IN 13, and is fixed in the working position by means of a roller 15 mounted on the lever 14,

The device works as follows.

The rotary sector 5 according to a predetermined program from the duck pattern formation mechanism, turning, brings to the working position one of the 4 thread holders 5 that are placed in the guides, which has its own groove. 2 comes in contact with a tooth; 8 crawling; CI. In this case, the roller 15 is transferred from the single slot 13 to the other.

The bottom frame 7 of the protrusion 8, by movement from the cam actuator (not shown), moves the thread holder 1 at the working position to the position for transferring the weft thread to the clamping shuttle.

The rotation of sector 5 to a new working position begins, without waiting for the end of movement of the holder 1, under the influence of the slider 7,

When turning, sector 5 tooth 8 of the slider 7 will gradually exit from the groove 2 of the holder 1, but their contact lasts until the holder takes up the rearmost position.
