To provide a manufacturing method for elevator cable that provides a high torsion suppression effect and does not require post-installation adjustment work for torsion improvement.SOLUTION: A manufacturing method for elevator cable, in which a wire comprising a plurality of strands twisted together and a plurality of wires are integrated by resin extrusion molding, comprises a step of rewinding in which a wire 3 is rewound from a first drum 5 to a second drum 6, and a step of extrusion molding in which the wire is fed out of the second drum 6 and extruded together with the plurality of wires. The step of rewinding is that the wire 3 wound on the first drum 5 is wound on the second drum 6 by relaxing the self-rotation.SELECTED DRAWING: Figure 3

    【課題】高い捻じれ抑制効果が得られると共に、捻じれ改善のための設置後の調整作業が不要なエレベータ用ケーブルの製造方法の提供。【解決手段】複数本の素線を撚り合わせてなるワイヤと複数本の電線とが樹脂の押出成形により一体化されたエレベータ用ケーブルの製造方法は、ワイヤ3を第1のドラム5から第2のドラム6に巻き替える巻き替え工程と、第2のドラム6からワイヤを送り出して複数本の電線と共に押出成形を行う押出成形工程とを有し、巻き替え工程において、第1のドラム5に巻かれたワイヤ3の自転性を緩和して第2のドラム6に巻き取る。【選択図】図3
