It performs die-cutting processing by continuous rotation in the form of a roller. It is one of the most productive models of die-cutting machines. During the die-cutting process of the circular knife die-cutting machine, multiple materials are compounded or separated, which involves the transportation of the main material belt and the slave material belt. The slave material belt needs to be pressed onto the main material belt before die-cutting. At present, the main material belt and the slave material belt of some die-cutting machines are fed synchronously, and the slave material belt is pressed in the non-die-cutting area of ​​the main material belt, which causes a waste of resources.
