Abstract
PURPOSE: To make it possible to take quantitative measurements of the shape of a strip easily and accurately by correcting and using outputs of detectors that are arranged in the width direction of the strip and send detection outputs proportional to tension.
CONSTITUTION: Strip 1 is sent out of mill rolls 5 and, while applied with tension T in the overall width direction, i.e. per width, wound around tension reel 6; and then tension T is detected by tension detector 7 and detectors 8i arranged in the width direction of strip 1 send outputs proportional to the tension. Sum total ΣSi of the outputs of detectors 8i is found from the ratio of tension T to sum total ΣSi, correction coefficient (k) is found, thereby correcting the outputs of respective detectors 8i by multiplying them by correction coefficient (k). Consequently, the defective shape of strip 1 is detected as the distribution of the absolute value of the tension from the distribution of each corrected value.
