To provide handrails for moving walkways in which the effect of prevention of charging due to friction with the guide rail is great and the running smoothness is good. In the handrail for moving walkways of this invention, surface canvas 5, which is woven by positioning conductive yarn or a string-shaped body as the warp or weft at specified spacing, and multiple sheets of polyester canvas 6 are laminated sandwiching strength maintenance members 7. Then core 4 is formed by press-fitting these as one using adhesive rubber and, at the same time, moulding them into a C-shaped cross-section. Cosmetic rubber layer 11 is provided incorporated over this. As the conductive yarn or string-shaped body, conductive yarn 10, in which carbon fibre 9 is wound spirally round the outer periphery of polyester yarn 8, or conducting string 12, which is conductive polyamido resin, into which carbon powder is blended, moulded into string shape, are used.

Cette invention concerne une main courante d'escalier mobile qui atténue considérablement la formation d'électricité statique par frottement contre la glissière et qui prévient bien les à-coups. La main courante selon la présente invention comporte, d'un côté, une toile 5 dont l'armure comprend des fils conducteurs de trame et de chaîne selon un espacement prédéfini et, de l'autre côté, une série de couches en polyester 6 stratifiées autour d'éléments de renfort 7. L'âme 4 de la main courante est réalisée par agglomération à la presse en présence de caoutchouc adhésif suivie d'un moulage en forme de C. L'objet de l'invention reçoit par la suite une couche de caoutchouc de propreté 11. Le fil conducteur 10 utilisé est un fil en polyester 8 autour duquel est spiralée une fibre de carbone 9 ou il s'agit d'une ficelle conductrice 12 en résine polyamide mélangée de poudre de carbone et moulée à la forme requise.
