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.

Open-end spinning apparatus

An open end spinning machine has individual spinning locations which include a spinning rotor, various drive rollers and conduits and drive shafts which are brought into tangential engagement with drive belts or the like. For this purpose, each spinning location is enclosed in a movable housing which can be displaced vertically on a column mounted on the machine by one end. A stop pin in the column cooperates with a rotating ring in the housing and provides therewith a bayonet-like engagement. The motion of the housing in the opposite direction is limited by the angled arm of a lost-motion slide connected to the housing which makes contact with the stop pin in the column. Easy removal without tools permits ready access to the machine space behind each housing.
