Flexible print mark detection for identification of the cutting position

Film on rolls is used on wrapping machines and the cutting position is detected using a print mark on the film. Reliable detection of the print marks is necessary to prevent defective products and increase productivity. The KT contrast sensors detect slight gray value differences between the mark and the background on matte, glossy, or transparent surfaces at maximum speeds. SICK offers a large selection of device types with different methods of contrast resolution and different teach-in variants.
