An anti-crimping roll is fixed to a vehicle moving in a direction perpendicular to the moving trace of a piston by way of a cylinder extending/shrinking the piston in a linear direction, and they are disposed at a position capable of moving along a longitudinal direction of a steel sheet within a plane in which the anti-crimping roll is perpendicular to the axis of rotation of a tension reel. A control device calculates an aimed winding angle of the steel sheet to the anti-crimping roll capable of avoiding occurrence of crimps based on a thickness and a width of the steel sheet, and drives the cylinder and the vehicle such that the calculated angle is aligned with an actual wind-up angle calculated from the stroke amount of the piston, moving amount of the vehicle to adjust the position of the anti-crimping roll. Since the position of the anti-crimping roll is automatically controlled depending, for example, on the change of the coil diameter during coiling, occurrence of crimps can be avoided easily without imposing burdens on an operator.

A method of controlling a form of a strip in a rolling mill. A plurality of paired data of manipulation amounts of form control actuators, and amounts of variations in the form of the strip corresponding to the manipulation amounts are prepared, as prototype manipulation examples. Calculation is performed to obtain a degree of similarity between an actual form error representing difference between an actual form of the strip and a target form, and variations in the form of the prototype manipulation examples. Then, actuator manipulation amounts of the prototype manipulation examples are weighted in accordance with calculated degree of the similarity, and the actuators are manipulated based on weighted actuator manipulation amounts.
