ABSTRACT:
An open-end spinning device (1) with a spinning rotor (17) which is mounted with its rotor shaft (8) in the V-slots of a support-disk bearing (5) and whose spinning cup (17) rotates at a high speed in a rotor housing (6) which is open to the front and can be loaded by suction. The rotor housing (6) can be closed by a pivotably mounted cover element (10) which comprises a sliver opening device and is arranged so that it can be disengaged if required. The cover element (10) comprises a locking and unlocking device (20) with locking bolts (23) which can be controlled in a defined manner and which are movably mounted in bearing brackets (22) of the cover element (10). The locking bolts (23) engage during spinning operation in bearing locations (34) on the spinning box frame (2). The cover element (10) can be readily taken off the spinning box frame (2), if required, by appropriately actuating the locking and unlocking device (20).
