A twin-wire belt press for dewatering of a fibre suspension and forming of a continuous web thereof comprises two dewatering tables (11, 12) forming a wedge-shaped pressure space (13) between wire belts (5,6) for initially pressing and dewatering the fibre suspension, whereby a web is formed between the wire belts. A roll arrangement (14) is situated after the dewatering tables, in the direction of movement of the wire belts, for finally pressing and dewatering the web between the wire belts. The roll arrangement comprises at least one perforated hole roll (15) pressing against the wire belts. As a result, water that the hole roll presses out of the web between the wire belts is drained at least in part through the hole roll without rewetting the web.
L'invention concerne une presse à double ceinture en toile permettant d'essorer une suspension fibreuse et de la transformer en bande continue. Cette presse comprend deux tables d'essorage (11, 12) formant un espace de pression cunéiforme (13) entre les ceintures en toile (5, 6) pour initialement presser et essorer la suspension fibreuse. On obtient ainsi une bande entre les ceintures en toile. Un système de rouleaux (14) est placé en aval des tables d'essorage, vu dans le sens de déplacement des ceintures en toile, pour finalement presser et essorer la bande entre les ceintures en toile. Le système de rouleaux comprend au moins un rouleau perforé (15) qui appuie sur les ceintures en toile. Ainsi, les eaux blanches, exprimées de la bande située entre les ceintures en toile par les rouleaux perforés, sont drainées au moins partiellement à travers les rouleaux perforés sans remouiller la bande.
