Tension Control for Slitting Machines
Slitting requires stable web tension from unwind through rewind to maintain edge quality and roll structure.
Why tension matters in slitting
Unstable tension can cause telescoping rolls, wrinkles, uneven slit edges, core shifting, and material stretch. A properly selected controller helps maintain consistent tension as roll diameter and line speed change.
Recommended control zones
- Unwind tension control for stable material feed.
- Intermediate tension control for process stability.
- Rewind tension or taper control for roll quality.
