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.
