1. In a conveyor which is adapted to elevate flowable products from a receiving station to a discharge station, the combination of, a flexible endless belt, a plurality of rollers upon which said belt is mounted with a product conveying run extending from said product receiving station along an upwardly inclined path to and around a roller at said product discharge station, said conveyor belt presenting a product conveying surface upon which the product is deposited and supported during the conveying movement, and a continuous array of closely nested cleats mounted on said belt along said product conveying surface, said cleats having a generally chevron-shaped configuration in plan with each of said cleats having two leg portions which extend respectively from the opposite side edges of said product conveying surface and which converge to an apex in the opposite direction to that of the belt movement, said leg portions being interconnected at said apex along the central portion of said product conveying surface and comprising a continuous base portion bonded to said belt and an integral upstanding flexible wall which is corrugated longitudinally and has a total wall height which is sufficient to permit the wall to remain substantially upright from said product supporting surface when said belt passes around one of said rollers, said cleats being bonded to said product conveying surface with the base portions thereof positioned adjacent each other and the apex of each cleat being located between the ends of an adjacent cleat, adjacent the apex of said adjacent cleat, to define a continuous array of overlapping and nested cleats whereby each pair of adjacent cleats defines a pocket therebetween with said product conveying surface during the upwardly inclined movement of said product conveying surfaces, to retain said flowable product therebetween, and the corrugations in said corrugated longitudinal walls of each of said cleats opening by flexing as they pass over said roller at said discharge opening while remaining upright to completely discHarge said flowable material from said pockets.
