Abstract
A method of manufacturing an escalator handrail which has a composite material including a metallic steel wire and a thermoplastic resin, said metallic steel wire having a center elemental wire and a plurality of strands placed so as to surround the center elemental wire, including: a preheating step of heating the metallic steel wire; a composite-material forming step of integrating the metallic steel wire heated in the preheating step with the thermoplastic resin in a molten state to thereby form the composite material; and a cooling step of cooling the composite material formed in the composite-material forming step.

A method of manufacturing an escalator handrail which comprises a composite material including a metallic steel wire, a canvas and a thermoplastic resin, said metallic steel wire having a center elemental wire and a plurality of strands placed so as to surround the center elemental wire, comprising:
- a preheating step of heating the metallic steel wire and the canvas together in a preheater;
- a composite-material forming step of integrating the metallic steel wire and the canvas heated together in the preheating step with the thermoplastic resin in a molten state to thereby form the composite material;
- and
- a cooling step of cooling the composite material formed in the composite-material forming step.
