Abstract

PURPOSE: To avoid losing tension balance at time of passing through a stand by degrading a speed command to a pinch roll driving motor in a ramp, when the tail edge of a strip to be wound on a coiler passes through the uppermost stand for adjusting tension.
CONSTITUTION: A pinch roll droop DR is multiplied 1 by a current IP (tension set value), and the output is applied to a ramp function generator 3 through a switch 2 which is closed on condition that the tail edge of a strip passes through an upperstream stand. After the speed bias Δu obtained here is subject to speed command processing 4 with a line synchronous velocity set value SL, the result is added to the output of a rotational frequency detector 7 of a top pinch roll motor 6 and an armature current value If detected by a current transformer 8. The result of the processing is output as a command value to an automatic speed regulator 9, and according to the output of the regulator 9, pinch roll motors 6, 14 located at the top and bottom are driven through an ignition signal generator 12 and a thyristor converter 1.
