Abstract
A system for measuring an amount of a rubber bank between rolls having a camera arranged in front of rubber banked between a pair of rolls for obtaining an image of the banked rubber. A screen acts as a background for the banked rubber when said screen is photographed by said camera along a straight line connecting the camera with the banked rubber. A light source irradiating light onto the screen illuminates by back lighting. A processor calculates the amount of the banked rubber from an image produced by the camera.
