Abstract

PURPOSE:To enable accurate control with quick response over a wide range of tension fluctuation, by compensating the speed of a dancer roll and the electrical current of an electric motor for driving the dancer roll, depending on the difference between the detected tension of a material and an aimed level. CONSTITUTION:When the difference between the detected tension of a material and an aimed level is not larger than a set value, a tension compensation signal TCS is cut by a function generator 23 so that a speed reference signal DELTATS is produced through the function generator and a proportional integrator 24. The signal DELTATS, a speed reference signal VR and the speed compensation signal PCS of a speed control system are applied to an adder 18 to regulate the speed of an electric motor 7 for driving a roll 3, through a speed control unit 11, to eliminate the difference between the tension and the aimed level. When the difference is larger than the set value, the speed compensation signal DELTATS is used to perform speed control through the electric motor 7 for driving the roll 3. At that time, since the output of the function generator 23 is effective, the tension compensation signal TCS is applied to a power supply control unit 13 to compensate the electrical current of an electric motor 10 for driving a dancer roll 4, to eliminate the difference between the tension and the aimed level.
