Applicable field: For cutting all kinds of printed packing Main features: 1.With PLC (Programmable Logic Controller) and HCI (Human-computer interface), the machine could calculate the tension automatically. 2.Slip differential air shaft and electrically controlled proportioning valve could compensate the tension slightly, and then it could solve the different thickness problem from the raw material or half-finished product. 3.With the servo driving and CCD (Charge-coupled Device) eye-mark tracking, the rectification speed would be faster and more accurately.
