Abstract
The invention relates to an assembly for producing a web of corrugated cardboard. The assembly has a corrugating device for producing a corrugated web, a glue application device for applying glue to the corrugated web and a pressure belt device which has an endless pressure belt guided around a deflection roller and a belt course regulating roller for pressing a cover layer against the corrugated web provided with glue. The pressure belt device has at least one pressure belt detection device associated to the pressure belt, the pressure belt detection device comprising a first pressure belt detection means for detecting the position of a first outer endless side edge of the pressure belt in the transverse direction thereof, a pressure belt regulating device in signal communication with the pressure belt detection device and an actuating device connected to the belt course regulating roller displacement device for displacing the belt course regulating roller depending on the regulating signals received from the pressure belt regulating device.
