<p>PURPOSE:To eliminate a defect on the surface of a strip, which is caused by sliding by measuring the tension of the strip in the entry and the delivery of a bridle roll, and controlling the torque of a clutch based on a result of said measurement. CONSTITUTION:Output signals of tension meters TM1, TM2 are inputted to an operation processor 19, and output signals of tension meters TM3, TM4 are inputted to an operation processor 20 and brought to operation processing. Based on output signals of the operation processors 19, 20, the torque of powder clutches P1, P2 and P3, and P4, P5 and P6 serving as slip-type clutches is controlled so taht a slide between bridle rolls 3, 4 and a strip 1 always becomes zero completely by following up a variation of substantial strip tension of the time of an operation.</p> |
