METHOD AND APPARATUS FOR COMPOUNDING RESIN AND FIBER

摘要

Molding material consisting of resin coated reinforcing fiber strands in a molten mass of resin is prepared at a molding site for controlled supply to a molding machine (64). Continuous strands (18, 20) of fiber from supply spool s (2, 4) are entrained with pressurized, molten resin flowing through a coatin g device and coated with the resin. The movement of the fiber and resin throug h the coating die (200) may be controlled so as to accurately and predictably produce any desired quantity of the molding material by operating in a discontinuous manner. The receiving device (16) may be the feed screw (66) f or an injection molding machine (64) or simply a plate movable to and from a compression molding machine. The fiber strands may be cut into predetermined lengths by a cutting device (92) positioned downstream of the aforesaid coating or conveying devices.
