! After cutting and spinning the glass using a furnace, high-frequency furnace, CO2 laser, oxyhydrogen flame, etc., the resin composition is completely applied and cured to maintain the virgin strength of the glass and to prevent future scratches. Therefore, a so-called tandem primary co-1 method is being investigated (see Japanese Patent Application Laid-Open No. 100734/1973).

厚の制御が難しいという欠点を有している。The die-stipping method, the felt method, the spray method, etc. have been used to apply this resin composition, but each method has its advantages and disadvantages, and the die-stipping method is preferred because it can be applied without contacting the fiber. The spray type is superior and is the most commonly used. However, the die coating method is incapable of forming a coating film with a thickness of 2 to 3μ711 or less, and the spray method requires that the optical fiber be coated uniformly with a coating thickness of 1. It has the disadvantage of being difficult to control.
ここに従来のスプレ一方式を用いる装りについて説明す
る。Here, a conventional one-spray system will be explained.

給装置である。In this case, in order to recover the resin composition sprayed from the sprayer 3 and to prevent it from adhering to peripheral equipment, the sprayer 3 performs the coating in a spray coating container 4 that is normally sealed except for the optical fiber passage hole. In addition, in the figure, 6 is a resin composition supply device.

ある。When such a spray application container 4 is used, this 41 part is equivalent to a sealed state, and the sprayer 3 can release 0.1 kg.
/ crlI~5 Kg/c! Because the entire resin composition is injected at a pressure of There's a problem.
以上説明したように、スプレ一方式は均一に塗布が難し

長Ｈｒがあり、本発明は従来の方θＰ合・改善して均一
な塗布ができる方法ｔ４に供しようとするものである。As explained above, it is difficult to apply the spray uniformly with the one-sided spray method, but it has the advantage of being able to apply to a thickness of 2 to 3 μm or less. This is intended to be applied to method t4, which enables coating.
以下第２図、第３図に示す実施例により本発明舎・説明
する。The present invention will be explained below with reference to the embodiments shown in FIGS. 2 and 3.

収されることになる。Further, an injection hole 12 of the sprayer 3 is formed laterally across the inner box 8 and the outer box 9, and when the resin composition is sprayed from the nozzle of the sprayer 3, the airflow from the nozzle passes through the optical fiber insertion. Hole 10. It intersects l1i-11+1m to reach the side wall of the inner box 8, and an exhaust hole 13 is formed at the position where this jet airflow reaches. The jetted airflow of the resin composition K is collected through the exhaust hole 13 in the space between the inner box 8 and the outer box 9.

ことになる。The melt-spun optical fiber 2 is completely passed through the upper and lower optical fiber insertion holes 10.11, and when it is fed out from below while being continuously spun, resin is sprayed onto the optical fiber 2 from the nozzle of the sprayer 3 in the lateral direction. The jetted airflow of the composition hits and coats the resin composition, and the jetted airflow of the resin composition that passes through the optical fiber 2 passes through the exhaust hole 1B, hits the outer wall of the outer box 9, and is dispersed into the inner box. 8 and the outer box 9.

越えて回収される。The provision of optical fiber insertion holes and injection holes is the same as in conventional devices, and when the resin composition is injected from the injection hole 12 with the nozzle of the sprayer 3, the jet airflow from the nozzle passes through the 10 optical fiber insertion holes. The connecting axis intersects with the side wall of the box 14, and an exhaust hole 13 is formed in this part.The above-mentioned exhaust blower 5 is installed in the exhaust pipe 15 connected to this exhaust hole 13, and the optical fiber is connected to the exhaust pipe 15. - The resin composition jet airflow that has passed through the exhaust blower 5 is forcibly collected by the exhaust blower 5.
