Detecting the end of the reel when unwinding material

When unwinding the tire material from the material bobbin, the end of the reel must be detected reliably so that the machine does not run empty. The material can vary in terms of width and thickness and have a shiny black surface. This presents a challenge for sensors when it comes to accurately detecting the edges. The Inspector 2D vision sensor reliably detects the edge, regardless of the different material properties.
