ABSTRACT:
A winding device for a yarn (1), in particular for winding a inelastic yarn (1) about a foundation (2). The device, optionally, includes a yarn guide unit (4) upstream from foundation (2). A rotary drive (5) for the foundation (2) and an unwinding device (6) for the yarn (1) are provided, with the unwinding device (6) including an unwinding drive (8) for unwinding yarn (1) from a supply package or yarn source (7). A yarn tension regulator (9) is embodied, in particular, as a compensating arm mechanism and which produces a feedback signal to an electrical or electronic control (10), such that even extreme yarn tension variations coming from the foundation are reduced and a largely constant yarn tension on the foundation can be achieved without problems. The yarn (1), close to and in front of foundation (2) or in front of upstream yarn guide unit (4) is guided through a speed detector (13), which provides a speed measurement signal to a control unit (10) with the unwinding speed of unwinding drive (8) controlled by the control unit (10) according to the speed measurement signal.
