Abstract
Drying section of a machine for producing a material web, such as a paper or cardboard web, comprises at least one drying group having at least one drying cylinder and at least one web guidance device around which the material web is guided in a meandering manner. The shrinkage gradient that occurs in the material web transversely with respect to the direction in which the web travels is set or controlled by providing at least one, and preferably several, areas in which an at least mostly free, unhindered shrinkage of the material web is possible.
