Abstract
A winding device for winding a yarn onto a package tube has a spindle that holds and rotationally drives the package tube. A support roller abuts against a peripheral surface of the yarn winding package during winding of the yarn. The spindle is supported by a pivotably mounted swivel arm so as to swivel relative to the support roller. A contact-force control device is provided and includes an actuator disposed to actuate the swivel arm, and a control device configured with the actuator. A bending beam load cell is configured on the swivel arm to determine an actual value of a contact force between the yarn package and the support roller. The contact force is regulated to a predetermined target value via control of the actuator by the control device.
