Abstract
PURPOSE: To greatly improve the accuracy of correcting work, by arranging a counter for starting the counting for the pulse generated from the pulse generator and converted to the distance value, and by comparing the counted value with the preset value in the setter by the comparator, and by controlling the correcting work according to the result of this comparison.
CONSTITUTION: A pulse generator 9 generates the pulse signal synchronously with the rotation of the correcting roll; the detectors 13, 13 are arranged in front of the feed-in side of the correcting roll; the timers 14, 14' work with the detecting signal produced from the detectors 13; the time-up signal of the timers 14, 14', as the roll- gap closing signal for the feed-in side correcting roll, is inputted to the roll gap adjusting devices 15, 15', 15", and at the same time, is inputted to the counter 11 as the count starting signal. The nondetecting signal of the detectors 13 is inputted, as the roll-gap opening signal for the feed-in side correcting roll, to the roll gap adjusting devices 15, 15; 15", and also is inputted to the counter 11 as the count starting signal. At the same time, the comparators 18, 18' compare the preset value of the setters 17, 17' with the counted value of the counter 11; if two values coincide each other, a work signal is successively sent to the roll gap adjusting devices 15, 15', 15" for the middle and following correcting rolls.
