Abstract

PURPOSE: To prepare a core line of optical fiber having fire resistance and heat resistance without damaging an elemental line at all, by forming an elemental line of optical fiber covered with metal with a heat insulating material sandwiched by them, wherein the layers of tapes of the heat insulating material and the metal cover are attached to the line tightly.
CONSTITUTION: The elemental line 1 of optical fiber obtained by subjecting a glass fiber to the first coating of a silicone resin and to the second coating of nylon is unwound. The asbesto paper 2 is subjected to 1/2 wrap winding on the unwound line to form the first covering layer, and the Al tape 3 is subjected to 1/2 wrap winding three times on the outside of the first covering layer, to form the second covering layer. After that, the surface of the Al tape is heated by the circular burner 6, the tape is passed through the dice 7 and fastened, the superimposed parts are bonded tightly and wound, to give a product.
