Patent number: 5954289Abstract: A method of producing a random wound yarn package includes driving a yarn package with a friction roller, setting and maintaining a constant yarn tension in the yarn, setting and maintaining a constant contact force between the friction roller and the yarn package being driven thereby, and temporarily regulating the yarn tension and the contact force during a time of a pattern winding zone of the winding process in order to maintain a constant winding density both before and during the time of the pattern winding zone. The winding station includes a friction roller for driving the yarn package, a yarn tensioner, a device that generates a constant contact force between the yarn package and the friction roller, and an evaluation and regulation unit that temporarily regulates the yarn tension generated by the yarn tensioner and the contact force generated by the device during the time of the pattern winding zone.Type: GrantFiled: June 26, 1997Date of Patent: September 21, 1999Assignee: W.

Patent number: 5826815Abstract: A yarn package (both conical and cylindrical) is produced at a winding station of a textile winding machine by alternately: accelerating the friction roller driving the yarn package with slippage between the friction roller and the entire surface of the yarn package; and decelerating the friction roller driving the yarn package without slippage between the friction roller and at least part of the surface of the yarn package, e.g., the neutral zone of a conical package. The periods (and thus the frequencies and angular velocities) of the friction roller and the yarn package are detected by sensors which communicate the detected values to a control and evaluation device. Based on the detected values during at least one phase of deceleration, the control and evaluation device estimates the yarn package radius during an acceleration phase.Type: GrantFiled: June 26, 1997Date of Patent: October 27, 1998Assignee: W.
