ABSTRACT:
In an open-end friction spinning process provisions are made for the fibers to be fed tangentially onto the surface of a hollow friction roller, at an angle to the longitudinal axis of said roller, whereby the fibers reach the spinning wedge in this position. In this manner, the fibers are arranged at a predetermined angle as they go from the fiber feeding channel to the spinning wedge and are brought into contact with the yarn end in this position which facilitates the joining process.
