ABSTRACT:
A set of ribs in a dewatering device in a paper machine which is used to support and/or to load the wire or wires in the paper machine and/or to doctor water from an inner face of a loop of the wire or wires. The set of ribs includes at least two transverse ribs placed one after the other at a distance from one another in the machine direction. The height positions of the ribs are adjustable and the ribs are interconnected in pairs by intermediate parts. The intermediate parts connect to the ribs by mechanisms of four articulated joints placed at a distance from one another in the transverse direction of the wire/wires so that the positions of the ribs in the horizontal direction remaining invariable irrespective of the height positions of the ribs in relation to one another. The intermediate parts and associated articulation mechanism are placed at a distance from one another in the vertical direction. The intermediate parts in the mechanism of four articulated joints are attached to the frame parts of the successive ribs by articulated joints so that one end of the intermediate part is attached to the frame by an articulated joint, and the other end of the part is attached to the frame of the other rib, respectively.
