Abstract
In a turret type yarn winder, a contact pressure acting on a roller bail by a yarn package is detected and used for controlling the rotation of a turret disc in accordance with the development of yarn layers on a bobbin so that the contact pressure is maintained at a predetermined value. A roller bail (5) detects a pressure acting thereon from a yarn package by a contact pressure sensor (7). If the detected contact pressure is higher than a target value, the turret disc (1) is driven in the direction to reduce the contact pressure. A driving torque of a motor (11) for driving the turret disc (1) is controlled in the normal/reverse direction by a signal corresponding to a deviation between the detected contact pressure and the target value so that the detected contact pressure coincides with the target value.
