Claim:
A twin-wire press for dewatering a fiber suspension, comprising a plurality of lower rolls, an endless lower wire that runs around said plurality of lower rolls, a plurality of upper rolls, an endless upper wire that runs around said plurality of upper rolls, thereby defining a longitudinal direction for said press, a first dewatering table and a second dewatering table supporting said endless upper and lower wires, respectively, said first and second dewatering tables being present at substantially the same longitudinal location of said press and forming a wedge-shaped dewatering space between said endless upper and lower wires in said longitudinal direction of said twin-wire press for initial pressing and dewatering of said fiber suspension entering said wedge-shaped dewatering space, whereby a fiber web of said dewatered fiber suspension is formed between said endless upper and lower wires, a roll arrangement positioned subsequent to said first and second dewatering tables in said longitudinal direction for final pressing and dewatering of said fiber web between said endless and lower wires, a press frame, said roll arrangement being provided in said press frame, a press and lift arrangement for vertically adjusting one of said first and second dewatering tables, and a link system having a first end and a second end, said first end of said link system joined by a first joint to said press frame and said second end of said link system joint by a second joint to said one of said first and second dewatering tables, whereby said one of said first and second dewatering tables is movable along its entire longitudinal extension in the direction from and against said other of said first and second dewatering tables by means of said press and lift arrangement such that a rear edge of said one of said first and second dewatering tables is vertically adjusted a substantially equal distance as a front edge of said one of said first and second dewatering tables, whereby said one of said first and second dewatering tables is vertically adjusted along its entire longitudinal extension.
