The process of sending label material from a roll or paper cutting machine to a cutting device using a label die-cutting machine. Usually, two rollers are used to feed the label. One roller is the driving roller, which is driven by a motor to move the label material forward; The other roller is a tension roller, which maintains the tension of the label material and ensures stable feed. Place the label material accurately on the cutting device so that the cutting device can cut according to the predetermined shape. There are two types of positioning methods: photoelectric positioning and mechanical positioning. Optoelectronic positioning determines the position by detecting the markings or holes on the label material through photoelectric sensors; Mechanical positioning is achieved through mechanical devices such as positioning pins, pneumatic positioning, robotic arms, etc.
