SJ-828 Automatic Tension Controller
Stable tension control solution for high-speed roll-to-roll web processing, rewinding, printing, coating and converting lines.
The SJ-828 automatic tension controller is designed for continuous web material production lines that require smooth, stable, and accurate tension control. With a no-overshoot PI algorithm, constant tension and taper tension modes, seamless auto/manual switching, and acceleration/deceleration compensation, it helps reduce tension fluctuation, prevent web stretching, and improve winding quality during high-speed production.
No-Overshoot PI Algorithm
The optimized PI control algorithm provides fast and smooth control response, helping avoid tension overshoot during start, stop, acceleration, and deceleration.
Dual Tension Modes
Supports both constant tension and taper tension control. Tension can be reduced automatically as winding diameter increases.
Seamless Auto / Manual Switch
Short press to switch working mode, and long press to capture current tension as the set value, enabling mode switching without machine stop or tension shock.
Acceleration Compensation
Built-in acceleration and deceleration coefficient adjustment keeps tension stable during high-speed running and speed changes.
Key Advantages
- Fast and smooth tension control without obvious overshoot.
- Suitable for easily stretched materials such as film and paper.
- Constant tension mode for stable web processing.
- Taper tension mode for improved winding quality.
- Automatic tension reduction helps prevent slipping, curling and poor roll formation.
Application Fields
- High-speed printing production lines.
- Coating and laminating equipment.
- Film and paper roll-to-roll processing.
- Rewinding and winding tension control.
- Flexible material converting and continuous web processing systems.
How It Improves Web Tension Control
Detect Tension Change
The system monitors the tension condition during start, stop, acceleration, deceleration and continuous running.
Calculate Smooth Output
The controller uses PI algorithm logic and compensation settings to calculate stable control output.
Maintain Stable Web
Stable tension output helps reduce web stretching, roll slipping, curling, and tension fluctuation.
