PURPOSE:To easily set the outer diameter of an FRP tubular member to be molded or the lamination state of reinforcing fiber bundles to an objective value. CONSTITUTION:A plurality of the reinforcing fiber yarns 3 delivered from a plurality of bobbins 2 are arranged to form a reinforcing fiber bindle 4 which is, in turn, impregnated with a resin to be wound around a mandrel 19 to produce an FRP tubular member. In this case, the reinforcing fiber yarns delivered from the bobbins 2 are arranged while the twist number thereof is controlled to form the reinforcing fiber bundle 4. |
