Advantages

⚙️ Motor Initiative Tension Control

Adopting motor initiative supplying tension advanced method, stable tension is maintained during foil winding, stopping and foil returning.

🔒 Auto-Lock Speed Reducer

Winding speed reducer is a turbine shaft reducer — it keeps the main shaft auto-locked whether in power-on or power-off status.

🎯 Photoelectric Analog Correction System

Uses photoelectric analog sensors that do not contact the foil edge, making it compatible with both thick and thin foil materials.

📱 Intuitive Touch Screen Display

Foil tension, coil parameters, and winding status can all be set and displayed on screen — easy to operate, accurate and intuitive.

🤖 PLC & Touch Screen Control

Controlled by PLC for fewer faults, no friction noise, stable working and high working efficiency.
