ABSTRACT:
The disclosure relates to open end friction spinning devices of the type having fibers supplied in an air stream to a yarn forming slot between two friction rollers driven in the same rotational direction. Auxiliary air supply arrangements are described for supplying an air flow to counteract the tendency of fibers to adhere to the friction roller rotating outwardly from the yarn forming slot. These auxiliary air supply arrangements also aid in returning and properly aligning fibers in the yarn forming region of the yarn forming slot.
