MACHINE FRAME FOR SUPPORTING DEWATERING ELEMENTS ABSTRACT OF THE DISCLOSURE A machine frame for supporting at least one dewatering element (for instance, a roll, suction box or the like) over which an endless belt (for instance a wire or felt) may travels upon operation of a paper manufacturing machine, having the following features: a) the dewatering element (10) has an operator-side end and a drive-side end; b) a beam (11) which extends substantially parallel to the dewatering element (10) is connected in torsionally rigid manner; b1) to a first frame part (12) for supporting the drive-side end of the dewatering element (10) and which rests in tilt-proof manner on a foundation (9); b2) and to a second frame part (13) for supporting the operator-side end of the dewatering element (10) and which rests on the foundation (9) via removable intermediate pieces (14); and c) an extension (15) of the beam (11) extends beyond the operator-side frame part (13), the outer end of the extension (16) being adapted to rest on the foundation (9), the improvement wherein: d) the beam (11) is arranged laterally alongside of the dewatering element (10); and e) the beam has a cross-section having a height (h) which is at least twice its width (b). Preferably the height is about 3 to 8 times the width. Advantageously, an additional beam (17) which also extends parallel to the dewatering elements (10) is arranged above the first beam (11) and is connected in torsionally rigid manner to upper frame parts (18, 19) for supporting a second dewatering element (for instance a roll 20) which is arranged laterally alongside the second beam (17). The two beams ( 11 and 17) are rigidly connected to each other at their drive-side ends so as to form a C-shaped structural part. The operator-side end of the second beam (17) may rest on the first beam (11) via a removable intermediate piece (21).
