PURPOSE: To wind a yarn on a foundation at a constant tension by forming a constitution for controlling a speed for unwinding the yarn in accordance with a speed for winding the yarn on the foundation. CONSTITUTION: An unwinding device 6 for a yarn 1 includes a storage spool 7 for the yarn 1, an unwinding drive part 8 for the yarn 1, a yarn tension regulator 9 particularly called a dancer arm facility, and an electrical or electronic control 10. The yarn 1, close to and in front of a foundation 2 or close to and in front of a previously placed guide unit 4, is guided through a speed detector 13, which provides a speed measurement signal to the control 10 with the unwinding speed of the unwinding drive 8 controlled by the control 10 according to the reference of the speed measurement signal. The resulting constitution winds the yarn 1 at a constant yarn tension.
