Abstract

PURPOSE:To display the sectional shapes corresponding to the moving speeds of a long size sheet successively, by measuring the sectional shapes of the sheet simultaneously with plural detectors, storing the signals thereof and calculating the distances of the continuous pattern signals. CONSTITUTION:When the preceding end of a moving long size sheet 1 arrives at a detecting part 2, the arrival is detected and the patterns of sectional shapes are inputted into an arithmetic part 3, and are stored therein; at the same time, the moving speed of the sheet 1 is detected with a detecting roll 5 and the pulse signal indicating the speed is inputted from a pulse generator 6 to the part 3. The distances between the respective measuring positions of the periodically measured patterns are calculated in the part 3, and the sectional shapes A-D,... corresponding to the moving speeds of the sheet are displayed in real time on a CRT display 4.

形状を測定するものであった。(Technical background of the invention and its problems) Conventionally, the cross-sectional shape of a moving long sheet such as a steel plate has been determined by scanning the detection part of a thickness needle in the width direction of the sheet. The purpose was to measure the cross-sectional shape oblique to the surface.
