Abstract

PURPOSE:To make slack quantity of catenary constant and to enable stable automatic operation by arranging means for controlling tension of the catenary part with weight of the catenary part. CONSTITUTION:The steel strip 1 forms the catenary in steel strip treating part 2. Bridle rolls 4 at outlet side are driven with a bridle driving device 4A at outlet side controlled with the velocity and the bridle rolls 3 at inlet side are driven with a bridle driving device 3A at inlet side controlled with the current. Pulse generator 5 tracks the connecting part of a strip to obtain the position thereof from the bridle roll 3 at the inlet side. The position is calculated with a tracking arithmetic unit 6A. Data of the tracking arithmetic unit 6A is inputted to a strip wt. arithmetic unit 6B to calculate the weight of the strip in the catenary part. Based on this strip weight, the tension value is calculated with a tension reference arithmetic unit 7. This tension is varied together with shifting of the connecting part and the catenary quantity is held constant.
