ABSTRACT:
In one embodiment, the invention comprises at least one roller with a plurality of recesses in its peripheral surface, mounted on the drive and trailing assemblies of a conveyor system. The recesses of each roller are angularly disposed relative to the central axes of their respective drive or trailing assemblies and are sized to receive a portion of an endless conveyor belt contacting the rollers. The bottom and size walls of the recesses act against the engaged portion of the belt to propel the belt through the system, support the belt and maintain the belt in proper tracking alignment. The recesses are preferably distributed in circumferential rows about the periphery of the roller and, in multi-row rollers, in a parallel relation across the width of the roller. A method for estimating the optimum size and configuration of the rollers of the invention for helical woven wire endless belts is also provided.
