本発明はＦＲＰ線条体の連続製造方法の改良に関するも

できる。<Prior Art and Problems> When manufacturing an FRP filament, a roving is impregnated with an ultraviolet curable resin, the resin-impregnated roving is molded with a molding die, and the surplus of the impregnated resin is squeezed out with the molding die. A method is known in which the resin is cured by ultraviolet irradiation immediately after this molding. By using high-power ultraviolet irradiation, the curing speed can be increased and the manufacturing speed can be increased.

条体に作用する抵抗が増大することが避けられず、細線
（０，４ｍｍｍｍ下）の場合、断線の懸念がある。However, when a high-power ultraviolet lamp is used, the molding die is heated due to its high output, and the curable resin squeezed by the molding die gels, and this gelation increases the resistance acting on the striatum. This is unavoidable, and in the case of thin wires (0.4 mm below), there is a risk of wire breakage.

張力の作用が、光ファイバーに悪影響を与える可能性が
犬であり、問題である。Particularly, in the case of manufacturing FRP-reinforced optical fibers in which an FRP layer is coated on the optical fibers, there is a possibility that the effect of high tensile force due to the above-mentioned increased resistance will have an adverse effect on the optical fibers, which is a problem.

法を提供することにある。<Objective of the Invention> The object of the present invention is to eliminate the gelation of squeezed resin in the molding die and to continuously produce ultraviolet-curable FRP filaments with low tensile force despite the use of high-output ultraviolet lamps. The goal is to provide a method that can be used.
〈発明の構成〉

Immediately after this molding, the resin is cured by UV irradiation.
In the method for manufacturing RP filaments, this method is characterized by squeezing out excess resin before the molding die.
〈実施例の説明〉 以下、図面により本発明を説明する。<Explanation of Examples> The present invention will be explained below with reference to the drawings.

ある。In FIG. 1, 1 is a resin tank for ultraviolet curable resin, and is equipped with a diaphragm bar 2. In FIG. 3 is a curing section, in which an ultraviolet lamp 4 (output of 5 W/cm or more) is installed. 4
0 is a reflective plate. 5 is a molding die provided at the entrance of the hardening section, and usually a round die is used. Reference numeral 6 denotes an auxiliary die provided in front of the molding die 5, and the hole cross-sectional area A1 of the auxiliary die 6 is equal to or slightly smaller than the hole cross-sectional area A2 of the molding die. If A1=KA2, then K
is 1 to 25. 7 is a pulling machine, and A is a roving.

で包まれるので、ロービングのはね上りをよく防止でき
る。To manufacture an FRP filament according to the present invention, the roving A is passed through a resin bath 1 to impregnate the roving with an ultraviolet curable resin, and the roving is passed through a squeezing bar 2 to guide the resin-impregnated roving to an auxiliary die 6. Until you get to dice 6,
The roving state is a flat state in which many fibers are arranged side by side. This resin-impregnated roving is passed through an auxiliary die 6 to squeeze out part or all of the excess resin. In this case, the roving is pushed toward the center of the die 6 and the outer periphery of the roving is covered with a sufficiently thick resin film, so that the roving can be effectively prevented from flying up.
補助ダイス６を通過した樹脂含浸ロービングを更に成形
ダイス５に通過させることによって、そのロービングを
所定の形状、断面寸法に成形する。The resin-impregnated roving that has passed through the auxiliary die 6 is further passed through the forming die 5 to form the roving into a predetermined shape and cross-sectional size.
この段階では、余剰樹脂を既に補助ダイスによりほぼ完
全に除去しであるから、樹脂の絞り出しがほとんどなく

。しかし、成形ダイス５においては余剰樹脂の絞り出し
がなく、樹脂の累積による溜りが実質上発生しないので
、成形ダイス５の樹脂のゲル化によるダイスつまりをよ
く排除できる。At this stage, the excess resin has already been almost completely removed by the auxiliary die, so there is almost no squeezing out of the resin and no displacement of the roving. The distance between the ultraviolet lamp 4 and the roving A' in the curing section 3 is usually several cm (
5 to 15 cIn), and since the molding die 5 is close to the UV lamp 4, if a high output UV lamp is used, the molding die will be heated due to its high output. However, in the molding die 5, there is no squeezing out of excess resin and there is virtually no accumulation of resin, so that clogging of the molding die 5 due to gelation of the resin can be effectively eliminated.
而して、成形ロービングを低張力で硬化部に通過させる
ことができ、この通過中に成形ロービングの含浸樹脂を
高圧紫外線照射により効率よく硬化させ得る。Thus, the molded roving can be passed through the hardening section under low tension, and during this passage, the resin impregnated in the molded roving can be efficiently cured by high-pressure ultraviolet irradiation.
上記において、補助ダイスには、ダイス孔断面積を順次
に大きくした敷部のダイスのタンデム配置を使用するこ
ともできる。In the above, for the auxiliary die, it is also possible to use a tandem arrangement of dies in the bottom section in which the cross-sectional area of the die hole is sequentially increased.

略してもよい。７は巻取機である。In FIG. 2, f is an optical fiber, and the outer periphery of the optical fiber may be coated with a buffer layer. 8 is a preform, for example a batten, which uniformly distributes the resin-impregnated roving around the optical fiber. 6 is as described above. 9 is a post-curing furnace, which may be omitted. 7 is a winder.

条体でも容易に製造することが可能である。<Effects of the Invention> According to the continuous production method of FRP filaments according to the present invention, as described above, even though the impregnated resin of the roving is hardened by high-pressure ultraviolet irradiation, the gelation of the resin pool in the molding die is prevented. It can effectively prevent die jam due to FRP.
Since it is possible to ensure that the striae is pulled under a low tension, even thin FRP striae can be easily manufactured.
