Features:

1. Five individual motors with ABB inverters synchronous control provides accurate web tension which is calculated by PLC.

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

3. Heavy-duty shaftless unwind with hydraulic auto loading for heavy jumbo rolls and web guiding system to detect the web position.

4. Special rewinding structure, two big drum rollers help to rewind at high speed stably.

5. Automatic hydraulic rolls unloading structure for rewinding shaft is convenient to unload the heavy rolls.

6. Fully automatic pneumatic knife adjustment, you just need to set the knife distance on a touch screen.

Standard Configurations:

Unwinding section: heavy-duty motor drive unwind

1. Floating type shaft-less unwind stand, 3” and 6” step chuck.
2. Hydraulic lifter for heavy jumbo roll, Max diameter 1800mm and Max weight 3600kg.
3. The Left and right arm is controlled by hydraulic and can be moved separately.
4. The web adjustment roller ensures the web tension balance from left to right.
5. Tension is calculated by PLC and controlled by two sets of motors automatically.
6. Web-guiding system: ultrasonic sensor(Pausource) to detect the web position.
7. Constant closed-loop tension control system: the tension is sensed by the load cell sensor and compared to the set tension.

Slitting section: motor drive

1. Knife rollers are driven by a motor
2. Pneumatic automatic rotary knife: full automatic, just need to set distance on touch screen, the knife can be moved to set position automatically.
3. Trim disposal: 3kw trim suction fan.

Rewinding section

1. Single rewind shaft surface winding structure, 1 pc 3” air shaft, the Max. rewind diameter 1500mm.
2. Two big drum rollers which are controlled by motors with gear reducers guarantee the stablity when high speed rewinding(600-800m/min)
3. Hydraulic lay-on big metal roller moving on guiding rails guarantees full contact between lay-on roller and slit roll, the lay-on pressure can be adjusted.
4. Hydraulic unloading system with pneumatic pusher helps heavy rolls unloading as well as efficiency during slit roll exchange.
5. Pneumatic lock for rewind shaft.
6. Banana roller to spread the web.
7. Protective cover for rewinder
