Abstract

PURPOSE:To make it possible to control constant tension with high precision, by means of a tension detector only, by estimatingly operating the backward tension from an actual speed value, an actual current value and an actual forward tension value of a roll driving motor. CONSTITUTION:A tension regulator 9 substracts a tension set value T'n from an actual forward tension value Tn with a tension detector 3 and outputs the tensile difference T. A speed regulator 10 outputs a signal in accordance with the added value of the tensile difference T and the carrier speed V'LS of a material 2. On the other hand, a state observation device 8 outputs a differential signal between a backward tension estimated value Tn+I estimated from a motor current actual value n of a motor 4 and a backward tension set value V'n+I. A current regulator 11 controls the current of the motor 4 in accordance with the added value of the outputs of the speed regulator 10 and the state observation device 8 and the actual motor current value I.
