PURPOSE:To raise a reinforcing effect by reinforcing resin, by forming a molding face of a metallic mold by a base material having a quality which is weak in its adjesive force with thermoplastic resin used as a reinforcing material, warming up this metallic mold in advance, and cooling molten resin fed forcibly. CONSTITUTION:On the molding part of a pair of metallic molds 5 which can be split in parallel with an optical fiber 3, a molding member 13 which is weak in its chemical adhesive force with thermoplastic resin 7 such as nylon used for covering as a reinforcing material, and has a smooth molding face is coated. On the molding face of this metallic mold, a connecting part 4 of the optical fiber which removes a covered layer 1 and melt-sticks and connects each optical fiber strand is positioned, and after that, a holding member 14 is fitted to both ends of the metallic mold 5. Between the metallic mold 5 and the holding member 14, an air hole 15 is provided, a heater 8' is fitted to the metallic mold 5, the resin 7 in an injecting vessel 6 is melted by a heater 8, simultaneously, the metallic mold is also warmed up by the heater 8', and the molten resin 7 is pushed softly into a gap between the molding face of the metallic mold 5 and the connecting part of the optical fiber 3 by a piston. |
