Abstract (en)
[origin: WO9949132A8] A paper machine for manufacturing soft paper comprises a press section (3) with a shoe press nip, through which a substantially impermeable belt (16) and a felt (15) run with the fibrous web (1) enclosed between them, a drying cylinder (5) and a transfer roll (17) forming a nip for transfer of the web to the drying cylinder. According to the invention the belt (16) comprises a carrier with a compressible polymer coating having a hardness of 50 to 97 Shore A, which polymer coating has a web-contacting surface with a degree of roughness in unloaded state of Rz=2-80 m, measured in accordance with ISO 4287, and a lower degree of roughness of Rz=0-20 m when the polymer coating is compressed by linear load of 20-220 kN/m on the belt as measured in a non-extended press nip, the belt and the web-carrying felt being arranged to run together not until they enter the press section, the belt running directly to the press section. Further, the belt runs from the shoe press to the drying cylinder to carry the web to the transfer nip, the felt running away from the belt before a water film formed in the nip on the belt breaks up. A device (31) is also provided for applying adhesive on the drying cylinder.
