Abstract

The invention relates to an apparatus, in particular a machine, for the pressing and dewatering or filtering of sludges, fibrous material suspensions or cellulosic material suspensions, having two circulating filter belts or screen belts between which the material to be pressed, dewatered or filtered is made to pass, and two circulating pressure belts or supporting belts for supporting said two filter belts on their sides facing away from the material to be treated, with supporting or pressure means, in particular stationary during the operation of the apparatus, for the pressure or supporting belts on their sides facing away from the filter belts or the material to be treated. The invention is characterized mainly in that the supporting or pressure means form a tunnel, in particular a pressure space, preferably with straight longitudinal axis, in the compression, dewatering and filtering zone, the pressure and supporting belts being sealed against the tunnel or pressure space walls directly or indirectly, locally defined, in particular in several loations of the tunnel or pressure space, by elastic belts or the like at least essentially enclosing the pressure or supporting belts and the filter belts and the material to be treated on all sides.
