APPARATUS FOR PRODUCTION OF FIBER-REINFORCED RESIN STRAND

摘要

To provide a manufacturing apparatus of a fiber-reinforced resin strand achieving excellent durability and capable of manufacturing a fiber-reinforced resin strand at a high production rate without causing slipping. In a manufacturing apparatus of a fiber-reinforced resin strand including spreaders 8 that spread a reinforcing fiber bundle 3 and are provided inside a crosshead 5 to which a molten resin material 2 is supplied continuously from an extruding machine 6, twisting rollers 11a and 11b that are provided at a downstream position from an exit nozzle 5a of the crosshead 5 and pultrude a fiber-reinforced resin strand 9 formed of a resin-impregnated fiber bundle from the exit nozzle 5a while imparting twists thereto, and twist retaining rollers 12a and 12b that are provided at a downstream position from the twisting rollers 11a and 11b and retain twists of the fiber-reinforced resin strand 9, all of the twisting rollers 11a and 11b and the twist retaining rollers 12a and 12b are made of metal with asperities being formed on the surface thereof.
