4.PLC program system for automatic tension control.

5. Unwinding is shaft-less, controlled by servo motor, with hydraulic type web rolls lifting.

6.Unwinding with EPC.     

7.Rewinding controlled by servo motor.   

8.Rewinding use double friction slippery shaft.

9.Traction controlled by servo motor

10.Imported PLC integrated control is used in electrical control system, human-machine communication is carried out by touch screen, Set and display working parameters according to the requirements from different products.

11.Servo motor is adopted for unwinding, roll diameter is automatically calculated by PLC to achieve automatic tension control, unwinder shaft-less with EPC. Hydraulic lifting web rolls system, easy unloading and loading material.

12.Servo motor is adopted for rewinding, active winding, roll diameter is automatically calculated by PLC to achieve automatic tension control, double slip air shaft for good & stable tension.

13. Using the flat knives for slitting , regularity disc surface , air exhausting device for waste .

14. In the system, there are calculations of meter, roll diameter, automatic machine stop when lack of material etc.

15. The system has perfect mechanical, electric and pneumatic design, also good safety protection.

16.Rewinding with double friction slippery shaft.
