Abstract
An open end spinning machine is provided with individual thread guides for each station. The thread guides direct compressed air along an axial channel in which the thread travels. The air expels the thread in the direction reverse to normal thread travel whenever it is desired to return a broken thread to the spinning chamber and rotor. The apparatus includes a thread cutting mechanism, disposed between the pneumatic thread guide and the spinning chamber, for cutting the thread to a fixed length so that it may be reattached to the fibers in the rotor without discontinuities.
