Abstract
In the case of a device for open-end rotor spinning, the axles of the spinning rotor, the supply roller and the opening roller--in plan view--are arranged in parallel planes to each other. In side view the axles of the supply roller and the opening roller are arranged inclined compared to the horizontal axle of the spinning rotor. A driving shaft extends perpendicularly to the above mentioned planes and drives the supply roller with a worm and a worm gear. The axle of the drive shaft is also the swivel axis for a hinged housing which supports the supply roller and the opening roller, the hinged housing also containing the cover for the spinning rotor. The hinged housing is supported independently from the rotor housing and is detachable at right angles to the swivel axis. Both the opening roller and the supply roller are accessible from the operational side when the hinged housing is in spinning position.
