ABSTRACT:
The invention relates to opening rollers for open-end spinning wherein the opening roller has a support part for attachment to the driving spindle and an adapter having the fiber engaging teeth of the roller. According to one aspect of the invention, the support part and adapter have a releasable connection which both establishes driving attachment of the adapter to the support part and secures the adapter on the support part without the intervention of a third element. The invention also includes an arrangement in which a screw screwed axially into the support part has a head received in a recess formed partly in the support part and partly in the adapter whereby the screw both establishes a driving connection between the two parts and secures the adapter to the support part.
