Abstract

[Problem] To provide a method and an apparatus for producing a reinforcing fiber-containing resin pellet which, even when a die having a wide width and a long die length is used in producing pellets each containing reinforcing fibers having a long fiber length, is capable of obtaining a stable strand, exhibiting an excellent appearance of a molded body, and exhibiting excellent mechanical properties. [Solution] A method for producing a reinforcing fiber-containing resin pellet comprises: a step for supplying, to a twin-screw extruder, a resin from the inlet side relative to a first kneading part and melt-kneading the resin in the first kneading part; a step for supplying, to the twin-screw extruder, reinforcing fibers from the outlet side relative to the first kneading part and the inlet side relative to a second kneading part and further melt-kneading the resin in the presence of the reinforcing fibers; and a step for extruding, from a nozzle outlet of a die and in the form of a strand of a reinforcing fiber-containing resin, the melt-kneaded resin containing the reinforcing fibers. The combination of a base and the die having a nozzle satisfies a specific condition. An apparatus for producing a reinforcing fiber-containing resin pellet is used for said method and comprises: a twin-screw extruder having a first kneading part and a second kneading part which is provided at the outlet side relative to the first kneading part and which is equipped with a reverse-feeding screw element having a notch and/or a kneading disk featuring reverse feeding; and a die part provided at an outlet of the twin screw extruder.
