Abstract (en)
[origin: WO2009024186A1] A pressing apparatus for a paper- or board-making machine for removing fluids from a web (W) by pressing comprises at least one belt which guides the web. The belt (20) is impervious to fluids and forms an endless loop. At least one nip is formed between a press roll (2) and a pressure means (1) of the pressing apparatus. The guided web is arranged to pass through the nip. The pressure means comprises at least one pressure chamber containing a pressure medium and extending along the length of the nip in the web moving direction such that the pressure medium directly contacts the belt. The pressure chamber has a pressure-operated sealing member (40) which cooperates with the belt, and the sealing operating pressure is adjusted in accordance with the pressure acting in the pressure chamber.
