ABSTRACT:
A conveyor belt, which is made of an elastic material, is made of a flat center piece which is flexurally rigid about the longitudinal axis of the belt owing to a transverse reinforcement and is but slightly extendible in the longitudinal direction owing to a longitudinal reinforcement; two flat edge pieces which are articulated to respective side edges of the center piece, are flexurally rigid about the longitudinal axis of the belt owing to a transverse reinforcement, are extendible in the longitudinal direction of the belt, and together have a width at least equal to the width of the center piece; and two link pieces which connect each respective edge piece with the center piece, are flexible about the longitudinal axis of the belt and extendible in the longitudinal direction of the belt, ar resilient to enable outward pivotal or folding movement of the edge pieces from a position in which the edge pieces are folded over the center piece, and have a width substantially smaller than that of the center piece. A longitudinal strip, which is fixedly connected to one side of the center piece and projects upwardly, is extendible in the longitudinal direction of the belt. The height of the strip is not substantially larger than the width of the link pieces and its transverse position on the center piece is such that the edge pieces, when folded over the center piece, are applied against the strip.
