ABSTRACT:
Apparatus for accommodating changing of bobbins on open-end spinning machines. Spooling devices are provided for joining a thread reserve section and a starting winding to an empty spool tube which is to be inserted in place of a completed bobbin. The spooling devices are constructed to form a starting winding of sufficient length to form a plurality of one-time piecing operations at a spinning station. A spool transfer device is provided for transferring a prepared spool with starting winding and reserve thread section into a bobbin holder. In certain preferred embodiments the spooling device is carried on a movable unit which travels along the spinning stations and includes an auxiliary bobbin for supplying the reserve and starting winding thread section. In other preferred embodiments, the spooling device is provided separate from the movable unit along the spinning machine and includes apparatus for forming and storing a plurality of pre-prepared bobbins. In the last-mentioned embodiment, the moving device and the spooling device include means for transferring the store of prepared starting bobbins to the moving device so that they can then be transferred to the respective bobbins.
