Abstract

Paper machines comprise press sections (3) with shoe press nips, through which substantially impermeable belts (16) and felt (15) run with the fibrous webs (1) enclosed between them, drying cylinders (5) and transfer rolls (17) forming nips for transfer of the webs to the drying cylinders.
Belts (16) have compressible polymer coatings having hardness of 50 to 97 Shore A, with web-contacting surfaces with a degree of roughness in unloaded state of 2m<Rz<80 m, and a lower degree of roughness of O<Rz<20 m when the polymer coating is compressed by linear load of 20 to 220 kN/m on the belt as measured in a non-extended press nip. Belts run from shoe presses to drying cylinders to carry webs to the transfer nips, the felts running away from the belts before a water film formed in the nip on the belt breaks up. Adhesive is applied on the drying cylinder.
