Abstract

PURPOSE: To change the tension while the looper angle is held at a prescribed position in controlling the sheet breadth, and to secure the stability of the sheet threading process, by operating the correcting amount for the roll's circumferential speed and the looper torque on the basis of the breadth deviation of a rolled sheet.
CONSTITUTION: A detector 4 detects the sheet breadth deviation ΔB which is then converted to a tension correcting amount Δσ* that is then inputted to an arithmetic unit 6. The arithmetic unit 6 then operates the correcting amount ΔV for the roll's circumferential speed of rolling rolls 2-1, 2-2 and the correcting amount Δq for the looper torque of a looper 3, and inputs them to a rolling roll driver 7 and a looper driver 8; hereby, the tension is changed while the looper angle is held constant, in order to control the sheet breadth.
