RW Counter Check is a treatment unit for self-adhesive labels on reels that rewinds clockwise or counterclockwise on different mandrel diameters, counts the labels through a progressive or regressive contactor, checks the presence of labels and stops in the presence of a missing label. RW Counter Check can rewind labels with an average rewinding speed of over 50 meters / minute starting from reels with a maximum diameter of 300 mm wound internally or externally, with a mandrel from 46 to 110 mm, to reels with a maximum diameter of 300 mm with unwinding internal or external.
