Title: Reinforcing band for conveyor belts, and conveyor belt using the same

Abstract: 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.
