Abstract
A covering for a machine for treating a material web, in particular a fibrous web, has a multilayer construction with at least two layers formed respectively by at least one polyurethane film, between which there lies a layer made of a reinforcement fabric whose mesh widths are selected such that the two adjacent layers of polyurethane film touch each other in the meshes. This covering can be used advantageously in particular as a transfer belt or a dryer fabric.
