Abstract

A method for producing a structured fibrous web, in particular a tissue web, includes bringing a fibrous suspension into contact with at least one structured forming belt and dewatering by using at least one dewatering element, in particular a suction element. The at least one structured forming belt includes a layer of polymer foam providing a paper-contacting side of the structured forming belt. The structure of the foam layer is at least partially transferred to the fibrous web. A structured forming belt and a machine for producing a fibrous web are also provided.
