The glass roving bundles 11, 11... whose external shapes have been adjusted are passed through each bundle and pulled out in the direction of the arrow, and the glass roving bundles 11, 11... are impregnated with ultraviolet rays from the high-pressure mercury lamps 15, 15... via the tubes 16, 16... The surface layer of the thermosetting resin is cured. Each transparent tube 16 has an inner diameter larger than the outer diameter of the glass roving bundle 11, and the outer diameter of each glass roving bundle 11 is adjusted by the drawing die 3, so that the uncured thermosetting resin The glass roving bundle 11 will not get stuck inside the transparent tube 16 and become clogged. In this embodiment, the transparent tubes 16 and 1 are pulled out at a drawing speed of 4 m/min.
6. When the atmospheric temperature inside the ultraviolet curing furnace 4 was set to 175°C while passing through the inside, and the length of the curing furnace 4 was set to 75 cm, the outer layer of the glass roving bundles 11, 11... I was able to harden it. At this time, an unsaturated polyester resin was used as the thermosetting resin, and a catalyst for accelerating photocuring was blended into the resin.

させることができるという効果がある。 As explained above, in the present invention, multiple hollow transparent tubes with an inner diameter larger than the outer diameter of the glass roving bundle are installed in the ultraviolet curing furnace, so ultraviolet rays are irradiated from the outside of the tubes. By doing this, the surface layer of the thermosetting resin impregnated into the glass roving bundle can be quickly hardened and the outer shape can be adjusted. Therefore, the present invention has the effect that the pultrusion speed can be increased and productivity can be improved compared to the conventional case of using a heated molding die.
又、透明管の内径をFRP棒状体の外径より大
きく形成させているから、透明管の内部に未硬化

詰まることがなく、円滑に作業を行なうことがで
きるという効果がある。 In addition, since the inner diameter of the transparent tube is larger than the outer diameter of the FRP rod, uncured thermosetting resin will not adhere to the inside of the transparent tube and clog the glass roving, allowing for smooth work. The effect is that it can be done.
又、本考案では、透明管の両端を紫外線硬化炉

う効果もある。 Further, in the present invention, since both ends of the transparent tube protrude outside the ultraviolet curing furnace, styrene monomer gas does not accumulate inside the curing furnace. Therefore, the present invention has the effect that the styrene monomer gas does not accumulate in the curing furnace and explode, making it safe.
