ABSTRACT:
The invention relates to an opening cylinder unit for open-end spinning machines. An opening cylinder (3) is mounted to transmit rotations on a shaft rotatable mounted in a bearing housing, which is covered at one front side by an axially fitted cover. The opening cylinder engages over the bearing housing forming a hollow space. In order that the hollow space can be freed from penetrated microdust in simple fashion, at least two cleaning ducts (15) disposed substantially in parallel to the axis of the opening cylinder are formed in the opening cylinder (3), which extend from the hollow space at least to one front side of the opening cylinder. The hollow space can be cleaned by these cleaning ducts using compressed air.
