Description

The invention relates to the textile industry and can be used in spinning production on carding, tape, tape connecting, combing, leveling, spinning, spinning, and the like.

The purpose of the invention is to simplify maintenance by ensuring that the fiber product is self-refueling at the oce-fO tension of the product and exiting it from

howl channel.

FIG. 1 shows a device, side view; in fig. 2 - the same, front view; in fig. 3 - the same, top view.

The device comprises a clamping pair | of rollers 1, in front of which a reel is fixed in the direction of movement of the fibrous product 2. Reel

represents a rod of diameter G-20 ka, a slight resistance to the movement of the semifinished product 3 and the maximum possible twist value in the oncoming branch.

6 mm, curved along a helical line with the formation of one and a half turns 3 with an angle of inclination d equal to 40-50, and an axial channel 4 for the passage of the fibrous product.

The ends of the rod are bent to form guide sections 5 for the fibrous product placed on one side in the radial direction. The inclination of the guide sections 5 to the middle of the turns of the reel allows the reel to be fastened in close proximity to the pair of rollers, which excludes the possibility of latent drawing during the turns of the coils and crosswise one relative 30 products.

The design of the proposed device will reduce to a minimum the time of filling the product into a reel, while retaining all the performance indicators j of similar devices. In this case, the guide portions 5 are connected at one end to the turns by means of transition sections 6 located on diametrically opposite sides with respect to the turns.

The free ends of 7 sections 5 are made straight and are arranged vertically from diametrically opposite sides of the coils at an angle to sections 5 equal to 25-30. Sections 5 of the reel are inclined to the middle part of the turns of the reel in its longitudinal direction. Loose ends 7 can

The design of the proposed device will reduce to a minimum the time of product refueling into the reel, while maintaining all the performance indicators j of such devices. Formula of the invention

A device for imparting a false twist to the product, containing a fixedly mounted in front of the clamping pair of rollers in the direction of movement of the fiber product, a reel, which is a rod.

to be bent into a convenient for fastening 45 curved along a helical line with an image configuration depending on the type and shape of one and a half turns and the axial profile of the equipment. The reel is fitted with an offset of the axis of its channel 4 relative to the line 8 of the clip of the rollers 1.

The device works as follows.

The fibrous product 2 is filled into a clamping pair of rollers 1, which, rotating, pulls it.

Under the action of tension, the product 2 slides along the guide sections 5 of the rod, lies in the middle zone of the turns of the reel and, by pulling, passes

for the passage of a fibrous product, characterized in that, in order to simplify servicing by providing self-refueling of the fibrous product in the axial channel, the ends of the rod are bent with the formation of coils located along the radial direction of the side a fibrous product located crosswise to one another and connected to the turns of the reel by means of diametrically opposed transitional sections of the rod 6 and self-directing into the axial channel 4 of the spiral of the reel. As the pair of rollers 1 rotates, the filled product moves along the 4 turns of the spiral-shaped part of the reel, thus obtaining a false twist, which strengthens and levels it.

coils due to the occurrence of sucrutine at the time of tension of the product, it is again self-replenished without the worker. The selected parameters of the number of turns, the inclination of the turns, the spatial arrangement and configuration of the guides ensure unimpeded self-filling of the semifinished product into the spiral part of the reel. The tilting of the guide sections 5 to the middle of the turns of the reel allows you to attach the reel in close proximity to a pair of rollers, which eliminates the appearance of hidden stretching in the semifinished product.

The design of the proposed device will reduce to a minimum the time of filling the product into a reel, while retaining all the performance indicators of such devices.
