Abstract

In the donning and doffing operation of a spinning machine, a tube (20) is pushed onto a packaged tube (14), whereby the thread (7) remains unbroken. The package (14) and the tube (20) are rotated together, until a few turns of the thread (7) are wound on to the tube (20). The tube (20) is subsequently held and the packaged tube containing the package (14) is removed. Subsequently, the empty spindle (15) is guided into the tube (20) for subsequent spinning operations without the necessity for removing overwindings which normally occur.
