Abstract (en)

[origin: EP2626324A2] The method involves supplying the thread by a yarn outlet unit in a continuous manner, where the sensory rotation pulses of a cross-wound bobbin (8) are detected. The timing of the rotation pulses is measured such that the respective driving diameter of the conical cross-wound bobbin is calculated. The speed of the bobbin drive roller (10) is balanced on the driving diameter. The detection of the speed pulses takes place before an application process at a non-wound cross-wound bobbin. An independent claim is included for a working station with a control unit.
