PRODUCTION METHOD AND PRODUCTION DEVICE FOR LONG FIBER-REINFORCED RESIN STRAND

摘要

A long fiber reinforced plastic strand production device is provided with: a rotary type haul-off machine which forms a long fiber reinforced plastic strand by drawing out a reinforcing fiber bundle which has been impregnated with a plastic from an impregnation head while rotating the reinforcing fiber bundle around the axis thereof to apply twists in the reinforcing fiber bundle, and draws in the formed long fiber reinforced plastic strand; and a rotary type winding-up machine which introduces the long fiber reinforced plastic strand drawn from the rotary type haul-off machine to a winding bobbin while rotating the long fiber reinforced plastic strand around the axis of the strand in the same direction as the rotation direction of the reinforcing fiber bundle rotated by the rotary type haul-off machine, and winds the rotated long fiber reinforced plastic strand around the winding bobbin. The rotary type winding-up machine is constituted to be capable of rotating the long fiber reinforced plastic strand at a number of rotation smaller than the number of rotation of the reinforcing fiber bundle by the rotary type haul-off machine.
