Abstract (en)
The belt (10) has fiber material layers (20, 22, 24, 26) i.e. thin fleece layers, fixedly connected with a carrying structure (12) e.g. fabric. The fiber material layers contain a polymer material i.e. polyurethane material, that covers the fibers of the fiber material layers partially as a polymer film. The content of the polymer material in the fiber material layers is different. The fiber material layers, whose fibers are covered with the polymer film, exhibit a permeability of maximum 7 cubic feet per minute. An independent claim is also included for a method for producing a belt for producing a sheet material.
