BG48524A1 - Method and device for manufacture of combined yarns from staple fibres - Google Patents

Abstract

This method and device are employed in the textile industry. The combined yarns produced are very soft, furry, and bulky. The method uses staple fibers of different types, content and length, which are combed and mechanically separated from the wire clothing. Initially their front ends are picked, falsely twisted by means of individually and fully drawing the clothing, and bound together with a binding yarn. The device consists of a mechanism for the feeding of fibers in the form of a sliver (1) to a wire clothing roller (3), furnished with a mechanism for the separation of fibers (4) from the clothing with means for the addition of a false twist (5) to the separated fibers. There is additionally a hollow spindle (6) and a winding mechanism (8). The mechanism for fiber separation (4) is comprised of fiber separators (9) arranged along the combing roller (2) with two adjacent rows of needles between each. The fiber separators (9) have the capability to consecutively rise over the needles of the wire clothing (3) in the area of fiber separation (18). The means for the addition of the false twist (5) is represented by a spinning nozzle placed between the area of fiber separation (18) and the hollow spindle (6).
