    Abstract: A tension member for an elevator system has an aspect ratio of greater than one, where aspect ratio is defined as the ratio of tension member width w to thickness t (w/t). The increase in aspect ratio results in a reduction in the maximum rope pressure and an increased flexibility as compared to conventional elevator ropes. As a result, smaller sheaves may be used with this type of tension member. In a particular embodiment, the tension member includes a plurality of individual load carrying cords encased within a common layer of coating. The coating layer separates the individual cords and defines an engagement surface for engaging a traction sheave. The individual cords are constructed of several strands and each strand is separated from direct contact with each other strand by polymeric material. While aspect ratios of greater than one are preferred, tension members of other ratios including round also benefit from the prevention of direct contact.

    Abstract: An elongated article such as a rope or cord having a series of fairings spaced apart along its length is produced in a continuous manner by the method and apparatus of the present invention. The rope comprises a core having a plurality of yarns surrounded by a layer of resilient material, and a braided jacket surrounds the core and anchors the fairings thereto. The fairings are provided by a resilient fairing yarn which is fed toward the core and which is manipulated by a needle during braiding of the jacket to cause each fairing to have a base portion anchored between the jacket and the resilient layer of the core and streamer portions extending outwardly from the base portion. The needle is mounted for reciprocation parallel to the moving core upstream of the braider, and the fairing yarn passes through the eye of the needle and a first length is displaced through the path of movement of the braid yarns into engagement with a gripping assembly located downstream of the braid yarns. The gripping assembly holds the first length of fairing yarn so that as the needle retracts, another length of braid yarn is pulled through the needle-eye. Continued operation of the braider causes the jacket to be applied around the portion of the fairing yarn engaged with the core, thereby forming the base portion for the next fairing. A control system is disclosed for synchronizing movement of the needle with the displacement of the rope and for adjusting of the spacing between the fairings.In another embodiment, a method and apparatus is disclosed for producing a faired article which does not have a separately-formed core.

    Abstract: A method of manufacturing an escalator handrail of the invention is characterized by including: a metallic steel-wire producing step of placing a center elemental wire and a plurality of strands so that the plurality of strands surrounds the center elemental wire, and applying tension to them so that each distance between the center elemental wire and each of the strands becomes the same, to thereby produce the metallic steel wire; a preheating step of heating the metallic steel wire to a temperature equal to or more than that of a thermoplastic resin in a molten state; a composite-material forming step of integrating the metallic steel wire heated with the thermoplastic resin in a molten state, and extruding them through a die finished into a cross-section shape of the escalator handrail to thereby form the composite material; and a cooling step of forcibly cooling the composite material.
