ABSTRACT:
A method for operating a dewatering press wherein a mass for wet fibrous material is dewatered on all six sides by compressing the mass with a second ram against a plurality of liners arranged on a front face of the second ram, on a rear face of a door, and on a top wall, a bottom wall, and two opposing side walls of a press box. Before entering the press box, a quantity of the mass of wet fibrous material is selected by a first ram which is guided a predetermined distance beneath a hopper of wet fibrous material by a pair of piston rods and cylinders arranged on opposite external sides of the first ram. On one side edge of the front face of the second ram and also on one side wall of the press box, there are positioned four-edged knives which cut off a selected quantity of wet fibrous material after such material is fed into the compression chamber but before such material is pushed into the press box by the second ram.
