Abstract (en)
[origin: EP0528752A1] By detecting the yarn length delivered from the drawing unit (5), the current wrap angle of the subsidiary winding can be calculated by the data-processing unit (20), thus making it possible to control the motors (7, 17) for the drawing unit and for the spindle shaft in such a way that a predetermined wrap angle of the subsidiary winding of especially 90 DEG to 270 DEG is maintained reliably and accurately. This makes it possible to prevent yarn residues from occurring in the sensitive spinning region during the doffing, thereby reducing the maintenance outlay for the ring spinning or twisting machine (1). <IMAGE>
