Abstract

A paper machine for manufacturing textured soft paper comprises a press section with a press nip, through which an impermeable belt and a felt run with the fibrous web between them, a drying cylinder and a transfer roll forming a nip for transfer of the web to the drying cylinder. According to the invention the belt is a texturing belt having a back layer and a web-contacting layer having depressions with surface portions situated between them to form a relief pattern in the web upon passage through the press nip, the texturing belt running from the press to the drying cylinder in order to carry the textured web to the transfer nip. The felt runs away from the texturing belt before a water film formed in the press nip on the texturing belt breaks up. A device is provided before the transfer nip to apply adhesive on the drying cylinder.
