PROBLEM TO BE SOLVED: To provide a moving handrail of a passenger conveyor for which a molding time is shortened, and wall thickness molding is performed while hanging-down of an ear part is suppressed.SOLUTION: A method of manufacturing a moving handrail of a passenger conveyor includes: a base material supply process for supplying a canvas 12 and a tension member 13 which are base materials to an extrusion molding die 1; a handrail extrusion molding process for applying thermoplastic resin supplied to the extrusion molding die 1 to the base materials, and molding a composite extrusion molded product in which the cross-sectional shape of the thermoplastic resin is C-shaped; and a cooling and solidifying process for forcibly cooling and solidifying the composite extrusion molded product which has been subjected to the handrail extrusion molding process while executing dimension correction. In the handrail extrusion molding process, an ear part of the composite extrusion molded product (a moving handrail ear part 4d) released from the extrusion molding die 1 is adjusted so that its lower side end part is not curved.SELECTED DRAWING: Figure 1
【課題】成形時間を短縮すると共に、耳部垂れを抑制しながら肉厚成形された乗客コンベアの移動手摺を提供することを目的とする。【解決手段】本発明の乗客コンベアの移動手摺の製造方法は、押出成形ダイス1に基材である帆布12及び抗張体13を供給する基材供給工程と、押出成形ダイス1に供給された熱可塑性樹脂を基材に塗布し、熱可塑性樹脂の断面形状がC字型形状である複合押出成形物を成形する手摺押出成形工程と、手摺押出成形工程を経た複合押出成形物を、寸法矯正をしながら強制冷却して固化する冷却固化工程と、を含む。手摺押出成形工程において、押出成形ダイス1から放出された複合押出成形物の耳部(移動手摺耳部4d)を、その下側端部が湾曲しないように調整することを特徴とする。【選択図】図1
