Abstract
During the run-up of a bobbin winding machine with a gap between the contact roller and the bobbin tube on a chuck, a disturbance in the speed (VTW) of the contact roller caused by the contact of the bobbin package on the bobbin tube with the contact roller is used for instantly switching on a controller for the speed control of the speed of the chuck. The time (t1), the direction as well as the magnitude of the change in speed of the contact roller during the contact are used for correcting the speed ramp of the chuck drive during a subsequent winding process. The detuning by different speeds of the surfaces of the contact roller and the bobbin package can also be used at any time during the whole package build-up for controlling the chuck speed.
