This demo displays Comptrol Inc.'s capabilities in the paper, foil, and film industries. Using calculated wrap angles, our tensioncells precisely measure material tension and can adjust spool speeds accordingly. Rolls of material can be monitored to reach a desired weight or diameter via programmable logic controllers. The entire system is controlled by a large, color touchscreen liquid crystal display. Analog tension indicators show material tension at different points along the system, and an anti-static tinsel bar is used to free the material of any electric charge.
