Device and method for producing a material web

A machine for the production of a fibrous web, the machine comprising:

• a revolving permeable belt having a first compressibility;
• a revolving permeable support belt having a second compressibility different than said first compressibility;
• a first press zone defined between said revolving permeable belt and said revolving permeable support belt, said first press zone having a first press zone length and configured so that a fluid can flow through said revolving permeable belt, the fibrous web and said revolving permeable support belt in at least a section of said first press zone length, the fibrous web being directed through said first press zone and arranged lying between said revolving permeable belt and said revolving permeable support belt;
• and
• a second press zone following said first press zone, said second press zone defined between said revolving permeable belt and said revolving permeable support belt and having a second press zone length, the fibrous web being carried through said second press zone between said revolving permeable belt and said revolving permeable support belt.
• a press element and a drying cylinder defining a third press zone through which the fibrous web is directed together with a clothing;
• and
• a plurality of devices for defining at least one of a selection and a combination of said first press zone, said second press zone and said third press zone.
