A tension control system is a mechanism designed to regulate and maintain the tension of a material, such as a web or a wire, during various manufacturing processes. This system ensures that the material being processed remains at a consistent tension level, which is crucial for achieving high-quality results in processes like printing, coating, laminating, and converting.

The tension control system typically consists of sensors, controllers, and actuators. Sensors detect the tension of the material, while controllers analyze the data and adjust the actuators accordingly to maintain the desired tension level. Actuators can include brakes, clutches, motors, or pneumatic devices that apply force to the material to either increase or decrease tension as needed.
