Abstract
For the purpose of cleaning an open-end spinning rotor, the fiber feed is usually interrupted and the open-end spinning rotor slowed down. Subsequently, in the case of many embodiments, after a cover is removed from the vacuum chamber, cleaning elements are inserted into the exposed rotor cup. According to the present invention, it is provided that before the open-end spinning rotor is actually uncovered, namely before it comes to a standstill, the cover is moved just a short distance away from the vacuum chamber and thereafter, that the vacuum chamber is again closed over momentarily. In this way, a fiber ring present in the inside of the rotor cup can be more easily removed before the actual cleaning of the open-end spinning rotor.
