Abstract

PURPOSE:To economically, high accurately control the draft position of the roll, by composing the equivalent backlash element equivalent to the backlash of the screw down device, and by inputting the output of the roll position detector to the backlash element on purpose to compare the output signal of the backlash element with the reference position. CONSTITUTION:The screw down motor 2 drives the shaft 3 according to the output of the position controller 1 and screws down the roll 7 in the housing 6 through the screw 5; then, the output signal X of the roll position detector 4, attached to the motor shaft 3, is inputted to the equivalent backlash element 11 equivalent to the backlash of the screw down device, for comparing the output signal Z of the element 11 as the feedback signal with the reference position. According to this constitution, the actual backlash 10 of the screw down device is equivalently realized at the equivalent backlash element 11 whose output signal Z becomes equal to the true roll position detecting signal; hereby, the draft position of the roll is high accurately, economically controlled.
