Abstract
A covering for a machine for the production of a fibrous web has, at least in some sections, a two-dimensional structure which is formed by a multiplicity of polymer-based regions which differ from each other at least in part by virtue of a different fraction of filler material and/or by virtue of a different type of filler material.
