What is a Tension Control System?
A tension control system keeps web material at a controlled force as it unwinds, processes, and rewinds through a roll-to-roll machine.
How a tension control system works
In a converting line, tension changes as roll diameter, speed, friction, and process load change. A tension controller compares the target tension with feedback from load cells or dancer position sensors, then adjusts brakes, clutches, motors, or drives to keep the web stable.
Main components
- Tension controller for signal processing and control output.
- Load cells or tension sensors for real-time feedback.
- Magnetic powder brakes, clutches, or drive systems for actuation.
- Operator interface for setpoint, calibration, and alarm handling.

FAQ
Is closed-loop tension control better?
Closed-loop control is preferred when tension accuracy and repeatability are critical.
What information is needed to select a system?
Material type, web width, line speed, tension range, roll diameter, and control zone are the key starting points.
