Web Tension Controller

A Web Tension Controller is used to maintain constant tension in continuous materials such as paper, film, foil, or fabric during processing. It works by measuring web tension through load cells or dancer rollers and comparing it with a preset value. The controller continuously adjusts motor speed or torque via drives or brakes to correct tension variations. This ensures smooth unwinding, processing, and rewinding of the material. Proper tension control prevents wrinkles, stretching, web breakage, and misalignment. Web Tension Controllers improve product quality, machine efficiency, and operational stability in printing, laminating, coating, and packaging industries.
