    15. Machine color: standard white (or as required)
  2. Unwinding Unit
    1. Structure: independent feed unit, shaft roll hydraulic lifting
    2. Shaft roll hydraulic feed frame, stops automatically when lift is completed
    3. LPC horizontal correction mechanism
    4. Automatic tension control
    5. Roll width range: 100~2000 mm
    6. Unwinding diameter (max): Φ1300 mm
    7. Unwinding pneumatic brake: 100 N.m x 2
    8. Edge guiding correction accuracy: ±0.4 mm
    9. Maximum unwinding load: 1500 kg
    10. Edge correction hydraulic cylinder
    11. Shaftless cone specifications: 3" or 6", 1 set
    12. Shaftless hydraulic loading and unwinding unit, fast and convenient vertical lift
    13. With edge guiding to ensure neat rewinding
    14. Tension includes magnetic powder tension unit and PLC; automatically calculates the winding diameter to achieve automatic tension control, which provides for full tension control
    15. Magnetic powder tension control unwinding allows the tension to be low, without residual torque, has high tension control precision
    16. The hydraulic cylinder for edge control includes an analog control, the unit does not vibrate
    17. U-shaped ultrasonic sensors/guides are included for edge correction, with high sensitivity
    18. A 30 mm wide guide rail is used underneath to achieve the edge correction
  3. Traction Drive
    1. AC vector inverter drive
    2. Synchronous belt drive
    3. Active traction rollers with steel roll structure
    4. Rotors are made of high-grade bearings
    5. Double roll on-roll, combined with soft steel
    6. Roller clutch, pressure regulating is achieved by the pneumatic components
    7. With the traction device, the unwinding tension and the winding tension can be controlled, so that the changes do not occur in winding or unwinding
    8. Because the rollers are balanced, the machine has no vibration therefore it runs smoothly
    9. Imported bearings make the rollers rotate smoothly at high speeds and reduce the noise of the whole machine
    10. The use of synchronous belts makes the speed transmission accurate, runs smoothly, and reduces the noise of the whole machine
    11. The machine is controlled by servo motor drives, which makes the system tension stable and with high accuracy
  4. Slitting
    1. Shear cutters
    2. The edge material is blown to the waste bin for collection by the exhaust fan in the slitting section
  5. Rewinding Unit
    1. Flat strip type air expansion shafts
    2. Rewinding shaft snap lock (easy to unload)
    3. Motorized active winding
    4. With automatic tension control
    5. Winding diameter (max): Φ1000 mm
    6. Winding motor power: 11 kW x 2 independent drives
    7. The air expansion shafts can be used for a wide range of materials
    8. The tension is automatically calculated by the PLC and the electric proportional valve, which makes the tension control of the material precise and accurate
    9. The motor's active winding enables a wide range of tension control range, no residual torque, and good tension control accuracy
    10. The asynchronous servo motor has high transmission accuracy
