Document Type and Number:
WIPO Patent Application WO/2023/153003
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an extrusion apparatus which can impart a stretching activity to a resin raw material while preventing the clogging of the resin raw material. The extrusion apparatus (1) according to one embodiment of the present disclosure is provided with: a cylinder (2) into which a resin raw material is supplied from a hopper (3); a discharge section (4) which is arranged at an end part of the cylinder (2) and from which the kneaded resin raw material is discharged; a screw (5) which is rotatably inserted into the cylinder (2), kneads the resin raw material, and conveys the resin raw material to the discharge section (4) side; a partitioning section (6) which is arranged between the cylinder (2) and the screw (5) and has, formed therein, a penetration part (61) through which the resin raw material passes; a first passage which is formed between the screw (5) and the partitioning section (6) and through which the resin raw material passes; and a second flow passage which is formed between the cylinder (2) and the partitioning section (6) and through which the resin raw material passes.
