Abstract
(EN)
The present invention relates to an apparatus (2) and a process for drying a fibre web (4), e.g. a web of paper or paperboard, the apparatus comprising an adjustable heated press nip (6) including at least one pressure device, such as a roll (8), supporting one side of the web (4) and at least two pressure shoes (10) opposite said device (8) and acting on the other side of the web (4), each of the pressure shoes (10) including means for providing an individual pressure (P1, P2, P3, P4, P5) respectively on the web, where at least one intermediate conduit (16) is arranged in-between said shoes (10), whereas the intermediate conduit (16) includes means (18, 20) which forms an additional individual pressure zone (24) on the web (4).
(FR)
L'invention concerne un appareil (2) destiné au séchage d'une bande de fibres (4), par exemple, une bande de papier ou de carton. L'appareil comprend entre les rouleaux une ligne de contact (6) chauffée et ajustable ainsi qu'au moins un dispositif de pression, tel un rouleau (8), qui supporte une face de la bande (4) et au moins deux patins presseurs (10) placés à l'opposé de ce dispositif (8) et agissant sur l'autre face de la bande (4). Chacun des patins de pression (10) comprend des moyens permettant de délivrer une pression individuelle (P1, P2, P3, P4, P5) respectivement sur la bande. Au moins un conduit intermédiaire (16) est placé entre ces deux patins (10) sachant que le conduit intermédiaire (16) comprend des moyens (18, 20) qui forment une zone de pression individuelle supplémentaire (24) sur la bande (4).
