<p>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 the 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, as seen 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 on perforated hole roll (15) pressing against the wire belts. As a result, white-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.</p> |
