An apparatus for treating fibre material containing liquid, comprising two rotating drums (2, 3), an endless driven belt (17) pervious to liquid and gas and extending between and passing around the surfaces (8, 9) of the drums, a feeding means (10) for the supply and a discharging means (13) for the removal of the fibre material, at least one container for collecting liquid, the liquid being displaced from the fibre material through the endless driven belt (17), a continuous wall means (18) impervious to liquid and gas and extending along a main part of and at a distance from the belt (17) from the feeding means (10) to the discharging means (13) in such a manner that a continuous space (19) is defined for the fibre material between said wall means (18) and the belt (17), and at least a part of the space (19), seen in the direction of movement of the belt (17), forms one or more treating zones where liquid is displaced from the fibre web through the movable belt (17) to one or more containers. According to the present invention the distance between belt (17) and wall means (18) is about 5-100 mm, preferably about 10-50 mm, and is chosen depending primarily on the fibre concentration of the fibre material so that the fibre material is moved by the moving belt (17) in the form of a fibre web substantially continuous in all directions through said space (19) in sliding contact with the wall means (18) with substantially no relative movement between the belt (17) and fibre web or layer thereof. 1987-05-20 (95) 376-PCT |
