(57) Abstract The present invention relates to support apparatus of a dewatering unit (30) below a bottom wire of the twin wire forming section of a paper or board machine. The problem in known, corresponding arrangements has been in- sufficient crosswise stiffness of the dewatering unit and lack of adjustability. The above-mentioned disadvantages have been eliminated or minimized by a supporting arrangement, characterized in that the dewatering unit (30) is supported on beams (36) trans- versely in view of the machine direction by means of hose-like pressure-medium filled elements (37), which also allow a longitudinal adjustment of the dewatering unit by means of an adjusting element (38).
