Abstract
A bearing and driving unit for a spinning rotor of an open-end spinning unit is provided. A braking element is provided for braking a rotor shaft, and a cleaning element is provided for cleaning the rotor shaft. Actuating elements are provided for activating and deactivating the braking element and the cleaning element. The cleaning element is applied to the rotor shaft with a contact force which is controlled independent of a contact force control of the braking element.
Claims17
Bearing and driving unit for a spinning rotor of an open-end spinning unit comprising:
- at least one spinning rotor unit having a rotor and a rotor shaft attached to said rotor;
- braking means for braking said rotor shaft when applied to said rotor shaft with a controlled contact force;
- cleaning means for cleaning said rotor shaft when applied to said rotor shaft with a controlled contact force;
- and
- actuating means for activating and deactivating said braking means and said cleaning means to activated and deactivated positions, said cleaning means contact force control being independent of said braking means contact force control.
Process for operating an open-end rotor spinning unit comprising:
- driving a rotor shaft upon which is attached a rotor;
- applying braking means to said rotor shaft with a controlled contact force during a braking operation;
- applying cleaning means to said rotor shaft with a controlled contact force during a cleaning operation during said braking operation;
- and
- activating said braking means and said cleaning means such that the cleaning means contact force control is independent of the braking means contact force control.
