Abstract:
An apparatus for open-end spinning comprising:an opening roller,a spinning rotor,a fiber feed channel for transporting fibers using a suction airflow from the opening roller to the spinning rotor, anda bypass air inlet opening located in an area of the opening roller and operable to support the suction airflow into the fiber feed channel;wherein said fiber feed channel tapers in a fiber transport direction, and has a deflecting zone on its transport path formed by adjoining fiber feed channel sections defining fiber feed paths inclined with respect to one another,wherein a bypass opening for drawing off a part of the suction airflow is provided at a distance upstream from a narrowest cross section at the fiber feed channel,wherein said bypass opening is arranged immediately after the beginning of the deflecting zone in an area which is substantially free of fibers due to deflection of the travel path of the fibers at the deflecting zone, andwherein the opening roller is disposed in an opening roller housing, which has a trash removal opening disposed ahead of the bypass air inlet opening with respect to an opening roller movement direction.
