Abstract:
A method and apparatus for manufacturing a continuous fiber-reinforced thermoplastic resin pellet are provided which can smoothly carry out a continuous drawing-out operation for a reinforcing fiber bundle (continuous fiber-reinforced resin strand).With respect to a terminal end of a reinforcing fiber bundle A of a roving package being exhausted and a front end of a reinforcing fiber bundle B of a new roving package, fiber quantity-halved end portions A1 and B1 each about half of the original fiber quantity are formed respectively, then reinforcing filaments in those fiber quantity-halved end portions are entangled by an air splicer to form an entangled portion C1, and reinforcing filaments in a portion downstream of the fiber quantity-halved end portion in the reinforcing fiber bundle B of the new roving package are entangled by an air splicer to form an entangled portion C2.
