Abstract (en)

[origin: WO2020064166A1] The invention relates to a machine (1) for producing a structured fibrous material web (2), the machine having: a forming area (3); at least one downstream press device (6), which comprises a press element (7) and a counter element (8) having a closed surface for forming a press gap (9); a permeable belt (4) having a web side (5) with a structure, which belt, together with the fibrous material web (2) lying on the web side (5), can be guided through the press gap (9) in such a manner that the fibrous material web (2) is separated at the end of the press gap (9) from the web side (5) of the permeable belt (4) and continues running with the counter element (8). The machine (1) according to the invention is distinguished in that the permeable belt (4) is designed as a water-absorbing press felt (4) and elevations (12) for generating the structure (13) are applied on the web side (5).
