Abstract (en)
[origin: EP2746206A2] The method involves generating an alternating slip by acceleration and deceleration between a drive drum (3) and a cross-wound bobbin (2). The driving drum is formed with a spiraled groove (9). Maximum speed of the drive drum and rotational speed of the cross-wound bobbin are recorded according to two function portions. Ratio of two time periods is determined. An acceleration phase of the drive drum is adjusted according to comparison of quotient with a reference value. A braking power is applied in a motor (7) for delaying the drive drum. An independent claim is also included for a device for wrapping a cross-wound bobbin.
