Abstract
A sliver opening device for an open-end spinning unit (1) with an opening cylinder (21) which rotates in an opening-cylinder housing (17) and comprises a base (29) arranged on a bearing shaft (26) with a replaceable annulus (30) of card-clothing fitted onto the base (29). The annulus (30) is held between an abutment flange (31) of the base (29) and a cover disk (33) of an enlarged diameter. The housing (17) and the cover disk (33) have mating stepped regions (45) at their outer circumferences to enclose and generally seal the housing. A visor-like shield (50) is arranged at a distance in front of the cover disk (33) to protect the cover disk from being touched inadvertently.
