Abstract
PURPOSE: To correct the shape of strip correspondingly to the pattern obtained from the strip shape as stated below, and to improve the reliability of measurement, by converting the continuously, optically measured surface shape of metallic strip to a pattern shape.
CONSTITUTION: A metallic strip 1 having edge stretches and center buckles is pretreated by the apparatus 2; a light 3a is irradiated obliquely from upside from a light source 3 in front of the bridle apparatus 5 upon the surface of strip 1 in order to measure the image lines 3b, 3c of edge stretches and center buckles by the camera 4; the results of measurement are transmitted to the converter 6. The results of measurement are converted to a pattern shape which is thereupon displayed on a rectangular coordinates; and correspondingly to this displayed pattern, the controller 7a is operated so as to actuate the bridle apparatus 5, 5' for giving a tension to the strip 1 whose surface shape is, under this condition, corrected by the work roll 7b through the backup roll 7c of the correcting apparatus 7. A light 3a' is irradiated from the light source 3' in the direction similar to above said direction upon the strip 1' whose image lines 3b', 3c' are measured by the camera 4', and the results of measurement are converted to a pattern by the converter 6; then, if the corrected shape is good, the strip 1' is coiled as the product 9 after passing the aftertreatment apparatus 8.
