Abstract:
1. A device for regulating the tension of a belt for pressing a web against the surface of a rotating drum in which the belt is deflected on rollers of which at least one comprises a force measuring roller, said force measuring roller comprising at least one force sensor for measuring the force applied by said force measuring roller on said belt and in which at least one of the rollers comprises a tension regulating roller position adjustably held by an actuating drive in an operative connection with said force sensor via a regulating device, said force sensor being in an operative connection with a correcting device that calculates the traction of said belt based on said force applied by said force measuring roller on said belt and a value dependent on the position of said force measuring roller and wherein the output of said correcting device is used by said regulating device in order to adjust the position of said force measuring roller.
