A multistage continuous rotary screw press assembly with the helical or spiral collars, vanes or ribs of each stage within the casing separated from those of an adjacent stage in the direction of material feed through the casing by a transition zone in which fixed material impingement elements, for example, knives, are mounted for dividing the material as it is expressed from one stage to the next adjacent stage in the material feeding direction.
