Slitting & Rewinding

Tension Control for Slitting and Rewinding Machines

Slitting machines need stable tension during acceleration, changing roll diameter and rewind build-up to protect edge quality and finished roll consistency.

Control Challenges

Common slitting defects linked to tension

Telescoping rolls

Poor tension balance can create roll shifting, loose edges and inconsistent roll hardness.

Edge quality variation

Web drift before knives can reduce slit accuracy and increase trim waste.

Diameter change response

Closed-loop feedback helps maintain target tension as unwind and rewind diameter changes.

Recommended Configuration
