[origin: WO2008041901A1] The present invention relates to a twin-wire press (50) for dewatering of a fibre suspension, comprising an endless lower wire (1.0) and an endless upper wire (12), an upper wire guiding member (20), a lower wire guiding member (18), such that a tapering dewatering space (6) is formed between the upper and lower wire guiding members, and sealing members (54) extending from an inlet box (8). The sealing members (54) in the twin-wire press comprises an upper and lower substantially form-stable sealing element (54', 54''), respectively, that in the tapering space (21) between the upper and lower wire guiding members (18, 20) is sealingly arranged against the upper and lower wire (10, 12), respectively.
