ABSTRACT:
An elastically deformable press cover of a press for dewatering web material, in particular of a dewatering press for paper making machines, or the like. The press cover surrounds a support and is an endless belt. At its outside, which faces toward the web, the press cover has ridges which lie in preferably equidistant diametral planes or run round the cover in the form of a helical line. Between the ridges there remain grooves which are open to the outside. As seen in cross-section, the top lands of the ridges are concave.
