ABSTRACT:
An open-end spinning unit includes a rotor housing and a rotor revolving in the rotor housing and having a fiber collecting groove formed therein defining a groove bottom. An apparatus for cleaning the rotor includes a cleaning device having a scraper to be positioned in a predetermined position in the fiber collecting groove of the rotor. The scraper automatically assumes an optimal length independently of its abrasion from wear upon entry of the cleaning device into the rotor, for assuring a secure placement of the scraper in the bottom of the fiber collecting groove.
