ABSTRACT:
The spinning rotor of an open-end spinning device is supported by means of a rotor shaft in the nip of at least one pair of supporting disks and can be driven by means of a tangential belt. A change-over device with a pressure roller is provided to press the tangential belt against the rotor shaft and a rotor brake which can be brought into action alternatively is provided. The change-over device is connected to a control lever which can be controlled as a function of the position of an actuator connected to a spinning station cover. The control lever is provided with an actuating arm. By opening the spinning station cover completely, a sufficient clearance can be produced between the actuator and the control lever so that the rotor brake can be deactivated through action exerted on the actuating arm of the control lever by means of the change-over lever on the one hand without allowing on the other hand the pressure roller to be yet actuated. The control lever can be made in several segments, with a first lever segment being connected to the change-over device and interacting with the actuator of the spinning station cover, while a second lever segment is provided with the actuating arm and interacts with the first lever segment.
