A durable reinforcing band for conveyer belts, wherein a reinforcing band (3) is formed by, interweaving a number of hard cords (6) facing a direction orthogonal to the longitudinal direction and longitudinally spaced at predetermined intervals with a number of longitudinally directed warp yarns (7) in such a manner as to prevent longitudinal shift, the reinforcing band (3) being disposed on the upper or lower surface of a core (2) composed of canvas or the like and being then surrounded by rubber (5), thereby forming a belt (1), and wherein the transverse stiffness and shape retainability of the belt can be enhanced by arranging the hard cords in a direction orthogonal to the longitudinal direction of the belt, and moreover, the hard cords are prevented from shifting longitudinally of the belt; and a conveyer belt, particularly pipe conveyer belt, using the same.

L'invention concerne une bande de renforcement longue durée destinée à des transporteurs à courroie. On forme une bande de renforcement (3) en entrelaçant un certain nombre de cordes dures (6) s'orientant dans une direction orthogonale par rapport à une direction longitudinale et étant espacées de façon longitudinale à des intervalles prédéterminés au moyen d'un certain nombre de fils de chaîne dirigés de façon longitudinale (7), de manière à prévenir un décalage longitudinal, la bande de renforcement (3) étant placée sur les surfaces supérieure et inférieure d'un noyau (2) composé de canevas ou analogue et étant entouré de caoutchouc (5), formant ainsi une courroie (1), la raideur transversale et le maintien de la forme de la courroie pouvant être améliorés par la disposition des cordes dures dans une direction orthogonale par rapport à la direction longitudinale de la courroie. De plus, les cordes dures ne peuvent pas se décaler, de façon longitudinale, de la courroie. L'invention concerne également un transporteur à courroie, notamment un transporteur à courroie tubulaire utilisant ladite bande.
