Abstract (en)
[origin: WO2009145697A1] 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.
