Abstract

1,012,766. Extruder screws. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. July 5, 1963 [Aug. 9, 1962], No. 30612/62. Heading B5A. An extrusion screw comprises a mixing section D composed of a series of eccentrically mounted discs 8, and an adjacent downstream flow resistance section E which, in conjunction with the extruder barrel 3 surrounding the screw 4, opposes discharge of plastic material from the mixing section D. A devolatilization zone F may follow immediately downstream of the flow resistance section E equipped with a vent part 2 in the barrel 3. An alternative embodiment in which the resistance section is constructed in the form of a screw thread opposed to the thread of the extruder is also described.
