A deviation is made zero between the detected value of a tension meter and a tension target value and also between the detected value of a looper angle 10 and its target value, by a looper control device 12. When the tension of the rolling stock 1 is in excess of a predetermined range, a correcting means 13 for a looper angle is actuated, outputs a corrected value of the looper angle target value and inputs it in the looper control device 12.  When tension deviates from a target value, a looper 7 properly operates, controlling the tension fluctuation; a stable and high precision rolling is therefore made possible.
