Abstract

A method and apparatus for individually piecing up yarn on an open-end spinning machine which has a spinning rotor and a rotor brake. A rotor cleaning apparatus is carried on a pivotal cover and is used for cleaning the rotor responsive to being activated. A pivotal lever which when moved relative to the cover simultaneously activates the rotor cleaning apparatus and the rotor brake causing the rotor to be cleaned as the rotor is being stopped. The yarn is pieced up when the rotor is being brought back up to running speed.
