This range of label slitter rewinder is available with a rotary die cutter. The working portions of the bed and cutting mechanism of the machine are cylindrical. During working, the printed paper is sent to the place between the die-plate roller and the pressure roller by the feeding roller. It is clamped and die cut. One revolution of the die-plate roller is an operating cycle. As the roller rotates continuously during working, the working efficiency is superior to many other die cutting machines. Similar with the FQ-320/450 products, this label slitting rewinding machine also has photoelectric deviation correction, automatic counting and other functions.
