Abstract

PURPOSE:To produce an optical fiber cable which has no pinholes in its protective pipe, and has less thermal effect on optical fiber strands by using a specific frictional driving extruder. CONSTITUTION:If a metallic material 13 is supplied from the leading end 11 of a pipeline 10, the material 13 is fed in toward the trailing end 12 of the pipeline 10 by the contact frictional resistance between a groove surface 7 and the material 13 along with the rotation of a driving wheel 6, by which it is exerted with pressure and is extruded through a pipe extrusion die 14 from an extruding chamber 16, and is thus formed into a pipe 5. On the other hand, if an optical fiber strand 4 is fed into the extruded pipe 5 through the core insertion hole 15 of a hollow mandrel 17, an optical fiber cable 3 is formed. Then, the extruded cable 3 is immediately cooled by a cooling trouch 18, thereafter it is wound by a coiler. Further, in the case of decreasing the outside diameter of the pipe 5, it is passed through a pipe elongating die 19 disposed in tandem and is drawn under the exertion of a pulling force T.
