されているものであつた。 Conventional fire-resistant and heat-resistant optical fiber cores include:
A structure in which an optical fiber is housed in a robust pipe, or a structure in which a metal coating layer is provided on the optical fiber wire either directly or with a fire-resistant or heat-resistant material interposed therein has been proposed. Of these, the metal coating layer is preferred because it has excellent fire and heat resistance and strength, and can be formed by vacuum vapor deposition, sputtering, ion plating, baking, plating, etc. of metals such as copper and aluminum. However, neither method causes thermal damage to the optical fiber wire.
Since there is a risk of mechanical or chemical damage being caused to the strands, there has been a need for a method for producing a fire-resistant and heat-resistant optical fiber core wire without causing any damage to the strands.

を密着せしめることを特徴とするものである。 As a result of extensive research in response to such demands, the present invention has discovered a method for manufacturing optical fiber core wires that are fire-resistant and heat-resistant without causing any damage to the optical fiber wires. be. That is, in the method of the present invention, a first coating layer made of a tape-shaped heat insulating material is provided on the outside of the optical fiber wire, a second coating layer made of a tape-shaped metal foil is placed on top of the first coating layer, and the edge of the tape-shaped metal foil is placed on the metal foil. The metal foils are provided so as to overlap each other, and then the metal foils are heated to an activated or semi-molten state and passed through a die to bring the overlapped portions of the metal foils into close contact.
本発明において第１被覆層の断熱材を設ける理

ける場合にクツシヨンを形成し、金属箔の被覆操
作を容易にすると共に金属箔を加熱するに際し前
記素線に影響を及ぼさないための断熱的作用をす
るためである。 The reason why the heat insulating material is provided as the first coating layer in the present invention is that when the second coating layer of metal foil is provided on the optical fiber wire, it forms a cushion, facilitates the coating operation of the metal foil, and heats the metal foil. This is because it has a heat insulating effect so as not to affect the strands when doing so.
なお断熱材としては通常のテープ状絶縁紙でも
よいが、特に耐熱性を有するシリカアルミナ（ア
スベスト）紙テープ、フエノール系樹脂紙テープ
等が好ましく、その厚さは20〜200μ程度のもの
を使用する。 The heat insulating material may be an ordinary tape-shaped insulating paper, but particularly heat-resistant silica-alumina (asbestos) paper tape, phenolic resin paper tape, etc. are preferred, and those having a thickness of about 20 to 200 microns are used.
又その被覆方法としてはラツプ巻又は縦沿え等
如何なる方法でもよく、その巻付回数についても
特に限定するものではない。 Further, the coating method may be any method such as wrap wrapping or longitudinal wrapping, and the number of wrappings is not particularly limited.
又金属箔による第２被覆層としては、通常銅、
アルミニウムの如く塑性加工が容易な金属箔を使
用するものであり、その厚さは数μ〜数百μ程度
のものである。 The second coating layer made of metal foil is usually made of copper,
A metal foil such as aluminum that is easily plastically worked is used, and its thickness is approximately several microns to several hundred microns.
その被覆方法としては前記と同様にラツプ巻又
は縦沿え等如何なる方法でもよく、その巻付回数
についても特に限定するものではない。 As for the covering method, any method such as lap winding or longitudinal winding may be used as described above, and the number of windings is not particularly limited.
この金属箔をラツプ巻き又は縦沿えした場合何

箔を巻付けたのみでは密着しえないため、該金属
箔を加熱しつゝダイス内を通過せしめることによ
つて金属箔は締付けられ十分に密着しうるもので
ある。 When this metal foil is lap-wound or vertically laid, overlaps occur, and these overlapping parts cannot be made to adhere tightly by simply wrapping the metal foil, so the metal foil is heated and passed through a die. By tightening the metal foil, the metal foil can be tightened and sufficiently adhered.
又本発明において金属箔を加熱して活性化する
とは金属箔を密着しやすい状態にすることを意味
するものである。 Furthermore, in the present invention, heating the metal foil to activate it means to bring the metal foil into a state where it is easy to adhere to the metal foil.
