    Abstract: PURPOSE:To ensure the adhesive properties and the smoothness of interface for the core and cladding, by forming the cladding of ion crystal by using an extruder having a crosshead die for a core fiber which is previously formed with the ion crystal. CONSTITUTION:A core fiber 1 of ion crystal is led into a pierced hole 5 of a mandrel 4 provided at the center part of a crosshead die 3 of an extruder 2. At the same time, the ion crystal powder 7 which is turned into a cladding is filled into a barrel 6. The powder 7 is pressed by a ram 9 heated by a heater 8 up to a temperature lower than the melting point to be plasticized, flows into the die 3 through the tip of the barrel 6, sticks to the outside of the fiber 1 which is led through the hole 5 at a lip part 10 to form a cladding 11. In this case, an end of the mandrel 4 is connected to a vacuum pump 14 through a pipe 13 to reduce the pressure within the mandrel 4.

    Abstract: PURPOSE:To prevent a breaking incident and to inhibit the pollution, oxidation, heat absorption, damage, etc. of a linear body by putting a metallic halide in a glass pipe and heating and drawing them. CONSTITUTION:The lower end of a low m.p. glass pipe 19 such as a lead glass pipe is formed into a circularly curved face, the upper end is kept open, and a metallic halide 20 such as TlBr, AgBr or AgBr+AgCl is put in the pipe 19. This pipe 19 is suspended in a frame 1 with holders 5, 6, and after evacuating the pipe 19 to a prescribed vacuum degree with a vacuum device 16, and inert gas is fed from a gas feeder 17. The lower end of the pipe 19 is then heated with a heating furnace 7 to melt the metallic halide 20 as well as to soften the glass, and by coiling the lower end of the pipe 19 with a coiler 18, a linear body 22 provided with a glass sheath is obtd.
