The invention concerns a pressing arrangement for a moving web (6), comprising apress roll (1) which forms a press zone (7) with a moving elastic belt (5) which is endless and supported by a counter body (2, 9). The outside of the belt is surface finished to a roughness which is more uniform than the side of the web contacting it. The press roll is heated to a temperature of at least 100 °C. The arrangement is principally intended for surface finishing of fiber mats such as paper or board. A method is indicated whereby preheating of the web prior to the press zone is achieved.

La surface extérieure de ladite courroie a une rugosité plus régulière que la face de la bande qui est en contact avec elle. Le rouleau de pression est chauffé à une température d'au moins 100 DEG C. Ce dispositif est conçu principalement pour la finition de surface de nappes de fibres constituant par exemple du papier ou un panneau. L'invention concerne un procédé comprenant le préchauffage de la bande avant son passage dans la zone de pression.
