Abstract

PURPOSE: To make the shape controller possible to correct the shape of even a composite wave, by installing a specified arithmetic device for correcting the set point signal to be inputted to each controller depending on the shape detecting signal.
CONSTITUTION: The setter 21 inputs such initial information as sheet breadth, quality of material, sheet thickness, draft percentage, etc., into the computer 23, which then operates the vertical bending force for the roll, the horizontal bending force for the roll, the forward and backward movements of the backup roll; on the other hand, the shape detector 22 inputs the shape detecting signal into the computer 23; the computer 23 operates the set point of each actuator from these data, and inputs it into each actuator. That is, the initial set point S0 for each of forward and backward movements of the backup roll 11 is operated by the computer 23 from the input for the sheet thickness, etc., and it is set at each jack 14 which is then driven by the controller 24; besides, the initial set point S0 is compared with the detecting signal of the sensor 25, inputted to the addition operator 26 as the feedback; if there is a difference from the initial set point S0, the addition operator 26 corrects it to the set point S0; hereby, the colsed loop control is carried out. Similarly, the vertical bending force F0, etc., is respectively controlled.
