Abstract
PURPOSE:To uniformize the breadth of the roughly rolled material, by computing and controlling the roll gap corresponding to the variation in the distance, from the front (rear) end of the rolled sheet under an edging pass to edging roll, according to the formula representing the fluctuation in the breadth of the rolled sheet as the function of the distance from the front (rear) end of the rolled sheet. CONSTITUTION:When the rolled material 1 arrives at the material's front end detector 7, the function generator 6, which has been waiting at the edger roll gap of the reference value, receives a signal from the detector 7, and delivers an output signal for DELTA (0) computed by placing x=o on the left and the right. The roll gap adjuster 5 adjusts the roll gap so as to change only DELTA (0) from above stated reference value, and waits for the feed-in of the front end of the rolled sheet into the roll. The change in the (x) with progress of following rolling work is detected by the revolution counter 8, and the distance from both ends of the rolled sheet is computed by the computer 9. As a result, the function generator 6 delivers an instruction for the renewed value of the edging DELTAx, on purpose to continue the controlling of the roll gap.
