ABSTRACT:
An assembly is provided for detachably supporting an opener roll and supporting opener roll shaft at an open end spinning unit. The assembly includes a housing defining a cylindrical receptacle, a bearing sleeve attached to the opener roll shaft to be movable therewith as a unit, and being selectively lockable in the receptacle. To accommodate locking of the bearing sleeve in the cylindrical receptacle, a pressure piece which is movable radially into a recess in the receptacle to engage against the bearing sleeve is provided, along with an adjustable locking mechanism connected to the pressure piece for accommodating movement thereof between the respective locking and unlocking positions. In preferred embodiments, the locking mechanism includes a lever portion in the area adjacent the opener roll, which area is exposed when the opener roll is exposed, so that the locking mechanism can be easily released and the opener roll can be then easily removed along with the bearing sleeve from the receptacle.
