Abstract

PURPOSE: To control the width of plate with high accuracy to target plate width by operating the roll opening of stand by delaying a hour alone required for metal belt to move between detector and stand according to the difference between plate width detected and target plate width.
CONSTITUTION: The inlet of the edger 5 is provided with the plate width detector 11, the plate width Wn detected and reference plate width set in the target plate width setter 12 are sent to the adder 13, and the plate width change amount Δ Wn calculated there is then sent to the delay circuit 14. The delay circuit 14 memorizes a plate width change amount corresponding to a position from the tip of a material which passed through the plate width detector 11 and at the same time sends to the arithmetic amplifier 15 a plate width change amount corresponding to the position of material which reached the roll inlet of Rn stand as much hours late as material moves from the plate width detector 11 to the Rn stand, whereby the roll opening Sn is operated through the amplifier 16 and the outlet plate width of the Rn stand is controlled constantly.
