  • Fiber feed arrangement for open-end friction spinning machines
    Patent number: 4567722
    Abstract: A fiber feed arrangement for an open-end friction spinning machines is disclosed. The fiber distribution zone in the wedge-shaped yarn forming gap formed by the friction rollers is configured in its size and/or its location relative to the friction rollers in dependence on the fiber length being processed and/or the desired yarn characteristic. In preferred embodiments the distribution zone is adjustable by means of at least one separate movable feed channel component in the area of the feed channel opening to the friction rollers.
