ABSTRACT:
A method for piecing on a thread in friction spinning machines, having at least one friction surface with a perforated wall defining a spinning wedge at the wall includes moving the friction surface, eliminating the movement of transport air through the perforated wall of the friction surface, supplying fibers to the spinning wedge, sucking away the fibers, subsequently moving a thread to be pieced on into the spinning wedge, resuming suction of transport air through the perforated wall of the friction surface, ending suction of the fibers, and continuously withdrawing the thread from the spinning wedge, and a device for carrying out the method.
