ABSTRACT:
A device serves to regulate the tension of a running belt. The belt is deflected on rollers of which one is designed as a force measuring roller and is connected to a displacement sensing device. This roller is provided with at least one force sensor that determines the force applied to the belt. In addition, this roller is position adjustably held by an actuating drive in order to be able to adjust the tension of the belt. The actuating drive is in an operative connection with a regulating device that is influenced by a correction device. This correction device determines the web tension from the force applied to the belt measured by the force sensor and from the position of the force measuring roller, that changes with the position of the tension regulating roller, and transmits this output as an actual value to the regulating device.
