Abstract

The invention relates to a dewatering device (10) in a paper machine or equivalent. The dewatering device comprises a suction box (11) including guide elements (12a, 12a, 12a3...) for a fabric (H1, H2), such as a wire, so that a pulp web (W) is arranged to run between the wires (H1 and H2) and the wire (H1) is arranged to run conforming to the guide elements (12a1, 12a2...) located in the suction box (11). The dewatering device (10) comprises second fabric guide elements (14a1, 14a2...) in the vicinity of the second wire (H2). Said fabric guide elements (14a1, 14a2...) are arranged to be movable towards and away from the wires/web (H1, W, H2) by means of loading devices (16a1, 16a2...).
