Summary: | To provide a method for manufacturing an optical fiber cable which has a wider residual strain control range of the optical fiber cable than ever before and is easier to control.SOLUTION: A method for manufacturing an optical fiber cable including a coated optical fiber (illustrated as a coated optical fiber tape 10) and a slot rod 20 having a slot groove for housing the coated optical fiber includes the steps of: twisting the slot rod before housing the coated optical fiber (illustrated as a winding device 37); housing the coated optical fiber in the twisted slot rod (illustrated as a gathering device 34); and resolving twisting of the slot rod by winding the slot rod housing the coated optical fiber (illustrated as the winding device 37).SELECTED DRAWING: Figure 1
【課題】従来に比べて光ファイバ心線の残留歪みの制御範囲が広く、制御しやすい光ファイバケーブルの製造方法を提供する。【解決手段】光ファイバ心線(光ファイバテープ心線10で例示)と、光ファイバ心線を収納するためのスロット溝を有するスロットロッド20と、を備えた光ファイバケーブルの製造方法である。光ファイバ心線を収納する前のスロットロッドを捻回するステップ(巻取装置37で例示)と、捻回したスロットロッドに光ファイバ心線を収納するステップ(集合装置34で例示)と、光ファイバ心線を収納したスロットロッドを巻き取ることにより、スロットロッドの捻回を解消させるステップ(巻取装置37で例示)と、を含む。【選択図】図1 |
