Features:

1.Three individual servo motors synchronous control and the big drum roller surface winding structure provide accurate web tension which is calculated by PLC.

2. Siemens PLC control system with touch screen brings much convenience for operator, it has multi-functions, like meter reached auto stop, tension auto control, and so on.

3. Shaftless unwind with hydraulic auto loading for heavy jumbo rolls and web guiding system to detect the web position.

4. Be equipped with rotary shear slitting knives and razor blade cutting system.

Standard configuration:

> Unwinding section
1. Floating type shaft-less unwind stand, 3”and 6” step chuck.

2. Hydraulic lifter for heavy jumbo roll, Max diameter 1400mm and Max weight 1800kg.

3. Left and right arm is controlled by hydraulic, and can be moved separately.

4. Web adjustment roller ensures the web tension balance from left to right.

5. Tension is calculated by PLC and controlled by magnetic brake automatically.

6. Web-guiding system: ultrasonic sensor to detect the web position

7. Constant closed-loop tension control system(optional): the tension is sensed by load cell sensor and compared to the set tension.
> Traction and drive
1. Servo motor is connected to the main drive roller.

2. Synchronous belt transmission.

3. Pneumatic nip rubber roller, the pressure of nip can be adjusted: providing perfect tension isolation
> Slitting section
