Abstract (en)
[origin: EP2172409A2] The method involves accelerating a winding shaft (23) and a thread traversing device (24) at a time point in a constant base speed, which lies below 30 percentage of operating speed. A thread draw-off device (13) is started and accelerated at another time point, where a thread (9) is removed from a clamping device by the thread draw-off device. The winding shaft and the thread traversing device are accelerated from the latter time point, and the thread draw-off device is accelerated upto to a third time point in a terminal velocity in a stationary spinning operation. An independent claim is also included for a cross wound bobbin of a textile machine.
