Abstract (en)

[origin: WO2020064167A1] The invention relates to a machine (1) for producing a fibrous web (2), in particular a tissue web, with at least one pressing device (6) which comprises a pressing element (7) and a counter-element (8) with a closed surface for forming a pressure nip (9), and with a water-absorbing belt (3) with a web side (4) and an opposite pressing element side (5) which can be guided together with the fibrous web (2) through the pressure nip (9) in such a way that the fibrous web (2) is separated at the end of the pressure nip from the web side (4) of the water-absorbing belt (3) and runs further with the counter-element (8). The machine (1) according to the invention is characterized in that the water-absorbing belt (3) comprises at least a first ply (15) and a second ply (16), and in that, as viewed in the thickness direction of the water-absorbing belt (3), the belt (3) has a layer (18) on the half which faces the pressing element (7), which layer (18) has a higher specific throughflow resistance than the first ply (15) and/or the second ply (16).
