Key Advantages

  • Motor-Initiative Tension Control Adopting motor initiative supplying tension advanced method, stable tension is maintained during foil winding, stopping and foil returning. It avoids loosen situations when tension is lost.
  • Turbine Shaft Speed Reducer The winding speed reducer is a turbine shaft reducer, which keeps the main shaft auto-locked in both power-on and power-off status for enhanced safety.
  • Photoelectric Analog Correction System Uses photoelectric analog sensors with no contact with the foil edge, compatible with both thick and thin foil materials.
  • Intuitive Digital Control Panel Foil tension, layer insulation, and coil parameters are displayed on screen for accurate, easy, and intuitive operation.
  • PLC & Touch Screen Control Controlled by high-performance PLC, resulting in fewer faults, no friction noise, and high working efficiency.
