1. A take-up speed detector 12 for detecting a take-up side speed of a web 1 to be tension controlled, a speed detector 10 for detecting a rotation speed of a take-up drum 8, and a take-up side of a take-up side of the web 1. Start-up·
A speed command calculator for controlling the rising / falling speed of the winding device so that the acceleration / deceleration curve is smooth by giving an optimum speed control signal using the output of the speed setter 15 which gives a stop command and the maximum speed command as an input. 16, a polarity reversing device 21 for reversing the polarity of the acceleration / deceleration amount, and an initial moment of inertia and an initial moment of inertia of a setting device 18, 19 for setting the initial moment of inertia and the initial outer diameter of the web 1 wound around the feeding drum 2. The inertial amount calculation unit 22 having a function of correcting the outer diameter and a function of calculating a tension fluctuation amount at the time of acceleration / deceleration from the reverse acceleration / deceleration amount output of the polarity reversing device 21 is provided. The load energy amount of the feeding device, which is suitable for the tension fluctuation due to the inertial force generated during acceleration / deceleration, is controlled by the acceleration / deceleration controlled so that the acceleration / deceleration curve is smooth and the feeding-side inertia moment. Inertia tension compensation winding feeding device to.
