Abstract

PURPOSE: To enable the shapes of strip form patterns to be known intuitionally and make the judgement of goodness or not of the shapes by expressing the strip shape patterns in terms of parameters indicating the differences in the rates of elongation to the center of the strip.
CONSTITUTION: Shape detectors 1 are provided in a plurality by leaving their detecting ends 2 therebetween and are disposed orthogonally in the strip pass direction R so as to detect the shape in the width direction of a strip S. The detecting ends 2 detect the rates of elongation at the respective points in the width direction of the strip S, output these as shape signals, and input these shape signals into a shape signal input unit 3. Based on the shape signals of the shape signal input unit 3, an electronic calculator 4 calculates parameters expressing the rates of elongation for the strip center. Hence, the shape is intuitionally known by the magnitude of the absolute values of the values of these parameters and positive and negative codes; in addition the goodness or not of the shape thus detected may be readily judged.
