Abstract
In order to clean the fibrous material supplied to the spinning rotors of open-end spinning units, removal openings for impurities are arranged in the area of the opener roller. These removal openings lead to collection chambers for the impurities. In order to permit these impurities to be removed from these collection chambers without any additional constructional effort for transport means having to be provided for each spinning unit and without this removal being able to have an unfavorable effect on the spinning process, this removal of impurities is handled by a travelling maintenance unit which removes the impurities from the collection chambers of the individual spinning units from time to time.
