Abstract
In the case of an apparatus for open-end spinning, a fiber feed channel is arranged between an opening roller and a spinning rotor, which fiber feed channel tapers in a transport direction and which comprises a deflecting zone on its transport path. Immediately after the beginning of the deflecting zone, a bypass opening is provided, through which opening a part of the suction airflow transporting the fibers to the spinning rotor is drawn off. In the area of the opening roller, a bypass air inlet opening is provided additionally to support the suction airflow.
