Fiber feed arrangement for friction spinning

摘要

An arrangement is disclosed for open-end friction spinning with two adjacently arranged friction rollers driven in the same rotational direction and forming a wedge shaped yarn forming gap. An inlet and opening device is provided for feeding single fibers to the wedge gap, and a yarn withdrawal device is provided for drawing off the yarn being produced in the longitudinal direction of the wedge gap. Between the inlet and opening device and the friction rollers a closed fiber feed channel is arranged which includes devices for reducing the flight speed of the fibers so that the optimum high speed operation of the opening device is facilitated while the fiber speed is subsequently reduced to optimize the yarn forming process.
