Method and device for the automatic removal of underwinding residues on spindles of ring-spinning or twisting machines

摘要

The invention relates to a method and a device for the automatic removal of underwinding residues on spindles 5 of ring-spinning or ring-twisting machines. Thus, with any automatic elimination of a thread break, an automatic removal of underwinding residues on spindles 5 of the ring-spinning or ring-twisting machine is carried out, and moreover the number of take-ups since the last automatic removal of underwinding residues is summed specifically to the workstations and, when an adjustable counting sum is reached, the automatic removal of underwinding residues is induced by the respective workstation via a control command, irrespective of the automatic elimination of a thread break. For this purpose, a thread-piecing unit 10 and a device 11 for the removal of underwinding residues are arranged on a common servicing traveller and are connected to a stationary control unit 12 consisting of a counting device 13, of a resetting device 18 and of a control unit 17 for the control commands. <IMAGE>
