ABSTRACT:
A process for producing glass fiber-reinforced thermoplastic resin pellets, which comprises a step of drawing out glass fiber strands from the inside of glass fiber rolls and introducing them into a resin impregnation die, a step of supplying a molten thermoplastic resin into the resin impregnation die and impregnating the glass fiber strands with the thermoplastic resin, a step of drawing out the glass fiber strands impregnated with the thermoplastic resin from the resin impregnation die and cooling and solidifying the thermoplastic resin to obtain a linear molded product, and a step of cutting the molded product into a predetermined length, wherein as the glass fibers, glass fiber strands drawn out from rolls, each roll obtained by bundling monofilaments having a diameter of from 6 to 25 μm and winding them so that the inner diameter will be from 18 to 50 cm, are used.
