  3. Machine Features
    1. Shear cut, dual-shaft face-interlaced winding (alternative score cut available).
    2. Photoelectric error correction for feeding and unwinding.
    3. Magnetic powder tension control for winding and unwinding.
    4. Frequency inverter control main machine electives.
  4. Unwinder
    1. Manual horizontal alignment eliminates tension and wrinkles caused by thick ends or uneven cores.
    2. Pneumatic brake controls unwinding tension; output torque is balanced, tension fluctuation minimized; Siemens PLC automatically detects material size and controls unwinding tension output.
    3. Hydraulic pressure lift loading for material loading.
    4. Shaftless unwinder with double pneumatic brake tension controlled by PLC.
    5. Web guide control system.
  5. Slitting System
    1. Round knife cutting for neat incision and long service life; upper and lower knife axes widened, speeds matched by gears; hand wheel for knife implementation and automatic cutting.
    2. Slitting shaft: 1 set top knife shaft and 1 set bottom knife shaft (score cut available on other position).
    3. Locking device with rapid tool setting device locks upper knife shaft to avoid cutting quality problems.
    4. High-pressure suction fan through suction pipe for waste discharge.
    5. 30 mm main wall plate: steel frame panels for effective vibration damping and smooth high-speed operation.
    6. Guide roller: Φ 100 × 1650 mm, chrome plated and polished.
  6. Rewinding Unit
    1. Two-axis rolling of left and right axles with pressure arm to balance pressure inside and outside winding; drive incorporates two magnetic powder clutches; uniaxial tension arbitrarily adjustable; winding tension increases with winding volume; PLC automatically calculates winding volume and control tension.
    2. Servo motor control rewinding; steel shaft rewinding of paper core with PLC control tension.
