Abstract

PURPOSE:To keep a constant tension by memorizing the tension variation of a long material in time sequence and executing the compensation so that the tension variation in the preceding time is offset in the net rewinding and automatically correcting the tension variation during rewinding. CONSTITUTION:If rewinding is started when an A-shaft electric motor 2 drives an A-shaft taking-up roll 1, a timer arranged on an A-shaft tension controller 8 starts time counting. In a rewinding tension variation compensating circuit, the tension variation compensation data No. is set to 1 in the initial value, and the pertinent compensation value is read. Then, in the tension instruction calculation circuit, the tension variation compensation value is added onto the tension instruction TREF. At the same time, in the rewinding tension variation compensation circuit, the variation portion is calculated from the difference between the tension instruction TREF and the tension detection value, and the tension variation compensation data is corrected. In the rewinding of the next taking-up roll, the tension variation compensation data is read at each sampling time, and the tension instruction in rewinding is changed, and the tension variation of a long material can be suppressed.
