SU44160A1 - Extraction device with endless straps - Google Patents

Description

In the proposed stretching device with the use of brackets, printed on the straps, the upper strap is forced to move on devices installed on carding, tape, bank and wadding machines, and additional fiber friction occurs during the stretching process, which is especially necessary for cotton wool. , and the wear of the leather is reduced, since all the friction of the fiber lies on the steel brackets, as a result of which it is possible to replace the leather straps with woven straps that can be woven from cotton Bulk or flax yarn.

In FIG. 1 shows a schematic view of the straps with brackets on the side; FIG. 2-view of the strap with a bracket in the section; FIG. 3-type strap with brackets on top; FIG. 4-view bracket.

The brackets 1 are made of steel wire about 1 mm in diameter and packed parallel to both the lower and upper straps 2 at a distance of about 3-4 mm from each other. The edges of the brackets bent on the inside of the straps enter into the grooved grooves on the surface of the cylinder 3 and the roller 4.

The protrusions formed from the wire lying on the strap are like grooves of the cylinder 3 and the roller 4, and each such lower strap protrusion enters the cavity forming between the two wires of the upper strap. As a result, the upper strap engages and therefore the latter receives a forced movement.

The subject matter of the invention.

Extraction device with endless straps. Characterized by the fact that in order to communicate the forced movement of the straps and additional friction to the fibers, brackets 1 of wire are applied, which are packed parallel to the straps 2 and entering with their curved edges on the inside of the straps into the grooved grooves on the surface of the cylinder 3 and the roller 4.
