Machine for producing a fiber web

A machine for at least one of producing or processing a fiber web or a tissue web, the machine comprising:

• a press roll defining a cross-machine direction and having a roll core, a roll cover surrounding said roll core and a central region and edge regions in said cross-machine direction;
• a mating roll being a drying cylinder or a Yankee cylinder, said mating roll forming a nip with said press roll, said mating roll having a circumferential surface with a contour running in said cross-machine direction, said contour changing during operation of the machine as compared to a standstill of the machine and said contour being curved during operation at least in some sections;
• and
• a multiplicity of at least one of pressure sensors or temperature sensors disposed at least one of in said roll cover or between said roll core and said roll cover, said sensors being spaced apart at different distances from one another in said cross-machine direction of said press roll, at least in some areas and said distances between said sensors being smaller in said edge regions than in said central region.
