Apparatus on a carding machine for processing textile fibres, for example cotton, synthetic fibres and the like, with a cylinder

Abstract

An apparatus on a carding machine for processing textile fibres, with a cylinder, has, in the preliminary carding zone, after carding zone and / or underneath carding zone, covering elements which lie opposite the cylinder clothing. A fixed carding element is associated with at least one cover element. The spacing of the cylinder clothing from the clothing of the fixed carding element is smaller than the spacing from the cover element. In order to reduce nep formation, to allow improved carding work and to give a better carding result, between at least one clothing strip of the fixed carding element and a cover element arranged upstream and / or downstream thereof, there is arranged an air guide element the spacing of which with respect to the cylinder clothing gradually decreases or increases.

Description

technical field [0001] The invention relates to an arrangement on a carding machine with a cylinder for processing textile fibers such as cotton, synthetic fibers, etc., wherein, in the preliminary carding zone, after the carding zone and / or below the carding zone, flat elements are located Opposite of a cylinder wire, where a fixed carding element is associated with at least one flat element, the distance between the cylinder wire relative to the wire of the fixed carding element (carding nip) is smaller than relative to the flat Spacing between elements. Background technique [0002] In fact, the flat element is only a small distance away from the outer surface of the clothing of the high-speed cylinder. In addition to the flats without clothing, there are usually also stationary carding elements covered with a clothing, which have at least one clothing belt. In many cases, the relatively short unwrapped flats run tangentially to the cylinder wires. [0003] In a known ...

AI Technical Summary

Problems solved by technology

As a result, air turbulence occurs upstream of the stationary carding elements, which undesirably leads to an increase in neps in the fiber material

A further problem is that turbulence leads to increased pressure differences at the stationary carding elements, leading to increased heating of the associated elements, resulting in higher fiber loads and clogging of the clothing belts of the stationary carding elements
