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.
Claims13
A winding device for winding a yarn onto a package tube to form a yarn winding package, comprising:
- a spindle configured to hold and rotationally driving the package tube about a longitudinal axis of the package tube;
- a support roller configured to abut against a peripheral surface of the yarn winding package during winding of the yarn;
- the spindle supported by at least one pivotably mounted swivel arm, wherein the spindle can swivel relative to the support roller;
- a contact-force control device, comprising:
- an actuator disposed to actuate the swivel arm;
- a control device configured with the actuator;
- a bending beam load cell configured on the swivel arm to determine an actual value of a contact force (FA) by which the yarn package and the support roller are pressed against one another;
- and
- wherein the contact force (FA) is regulated to a predetermined target value via control of the actuator by the control device.
