Abstract

PURPOSE:To provide a thermoplastic resin kneading extruder which has large extrusion capactity and small back pressure with preferable resin kneading and dispersion performance by providing to a shaft at the extrusion end of the extruder a specific gap part expanding radially. CONSTITUTION:In a resin extruder in which a rotary screw 11 (reference numeral 11a represents fins) is inserted into a cylinder 10, a disc 12 is provided at the end of the screw 11 to form a gap radially expanding between the disc and the cylinder 10, and a number of kneading grooves 13 are formed on the end face 12a of the disc 12 and the inner peripheral end 10a of the cylinder 10 facing to each other.
