摘要： The invention relates to a twin wire press (2) for dewatering a fibre suspension, comprising a lower wire (8) and an upper wire (10) between which a fibre web (F) is formed. An arrangement of rolls (4) comprises a first dewatering control means (22) having a dewatering element (24) forming a press nip (25) with a first roll (26) (or a second dewatering control means), where the element and the first roll, (or alternative second control means), along a section of the press nip where they bear on each other, are adapted to each other to provide a thickness profile designed to provide a dewatering profile, and where the element presses the formed web (F) against the first roll, or the alternative second control means, via the wires, whereby water pressed from the web is drained through the element. The invention also concerns a method for dewatering a fibre suspension.

摘要： 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.
