Abstract:
A device for regulating the tension of a moving web of material, in particular a web of paper in a paper-working machine such as a corrugating machine, comprisinga machine frame (19); a first roller (21) that is mounted for rotation about a first axis of rotation (23) in relation to the machine frame (19), taking up a web of material (4) by an angle of contact a; and a supporting device, which supports itself on the machine frame (19), which is mounted for pivoting about the first axis of rotation (23) by a pivoting drive, and which supports at least a second roller (28, 29) mounted for rotation about a second axis of rotation (30, 31) that is substantially parallel to the first axis of rotation (23); wherein the angle of contact a of the web of material (4) on the first roller (21) is modifiable by the at least one second roller (28, 29) being pivoted about the first roller (21); wherein a humidifier unit (40; 40â€²) is provided for the supply of humidity to the web of material (4); wherein the web of material (4) has a conveying direction and the humidifier unit (40; 40â€²) is disposed upstream of at least one of the first roller (21) and second roller (28; 29) along the web of material (4); and wherein the humidifier unit (40; 40â€²) is disposed on a side of the web of material (4) that is turned towards the first roller (21).
