Abstract

A screw apparatus comprises a melting extruder for melting a resin; a screw unit for kneading molten resin and reinforcing fibers to obtain a reinforcing fiber-containing molten resin and supplying it; and a mixer in which at least a part of the reinforcing fibers attach to the molten resin which is extruded from the melting extruder and flows down owing to gravity in an open space, and then the reinforcing fibers and the molten resin are fed into the screw unit.
