WEB TENSION REGULATOR

The BZR tension regulator

The BZR tension regulator maintains constant web tension even when the outside diameter of the reel varies.The outside diameter is measured by ultrasonic, eliminating the need for any direct contact with the product. The ultrasonic signal is converted by the central control unit into an air pressure value, to control a brake or a torque limiter. The pressure is regulated in such a way that the torque takes account of the outside diameter of the reel concerned, to ensure constant tension.
