Abstract
A machine for producing and/or processing a fiber web, in particular a tissue web, includes a press roll and a mating roll which forms a nip with the press roll and the circumferential surface of which has a contour running in the cross-machine direction which, during operation of the machine, changes as compared with when the machine is at a standstill. The press roll has a roll core and a roll cover surrounding the roll core. Multiple pressure and/or temperature sensors are disposed in the roll cover and/or between the roll core and the roll cover. The pressure and/or temperature sensors are spaced apart differently far from one another in the cross-machine direction of the press roll, at least in some areas.
