Title:

COMPOSITE MATERIAL PRESS MOLDING SYSTEM AND KNEADER/EXTRUDER USING SAME

Document Type and Number:

WIPO Patent Application WO/2015/190340

Kind Code:

A1

Abstract:

The present invention provides a kneader/extruder that is provided with a heating cylinder (16), a screw (17) housed in the heating cylinder (16) so as to be capable of rotation and forward/backward movement, and a die (18) attached to the tip of the heating cylinder (16), and generates a plastic compound (6) having a reinforcement fiber kneaded therein, said kneader/extruder being provided with a shutter member (19) that opens and closes a compound extrusion port (18a) provided in the die (18), and performing kneading and extrusion of the compound (6) intermittently. The shutter member (19) may be provided with a scraper (20) that scrapes the compound (6) off from the surface of the die (18). Due to this, this kneader/extruder can generate a one-press portion of the compound and can be easily maintained.
