PURPOSE: To prevent reinforced fiber from scattering into the atmosphere without providing particularly a cutting device for reinforced fiber by feeding the reinforced fiber in the long fiber state into a kneading device while a resin material is kneaded by means of a multi-screw kneading device, cutting the reinforced fiber in the kneading device and dispersing the same into a resin material as the reinforced fiber of short fiber shape.
CONSTITUTION: Thermosetting resin and an inorganic filler are fed quantitatively and continuously at the constant ratio into a casing 11 through respective feeding inlets 13a and 13b. Both materials are fed into a filler kneading section M1 while both materials are mixed in a carrying section T1. Then, the both materials are kneaded strongly in a kneading section M1 while being pushed back at a backflow section R1. A kneaded material is fed into a carrying section T2 by the extrusion pressure from the upstream side at the carrying section T1. Further reinforced fiber is fed from a reinforced fiber feeding section 13c provided at the carrying section T2 into the casing 11 continuously. Said materials are kneaded strongly at a reinforced fiber kneading section M2 by the action of a backflow section R2, and a glass roving F is cut into various kinds of dimensions in the casing 11.
