BIAXIAL EXTRUDER

摘要

PROBLEM TO BE SOLVED: To provide a biaxial extruder which makes it possible to improve the treating capacity at the time of kneading extrusion of extruding material and to improve the quality of a molding. SOLUTION: The two screws 7 of a feeder are constituted by one stripe of flight screws where flights 17 protrude from the outer periphery of a shaft. A cutout surface 18 perpendicular to the axial central direction of the screw is formed on the sidewall of one side to become the extruded surface of an extruding material U at the flights 17 of the respective feed screws 7.
