Abstract
In one embodiment, the invention comprises at least one, and preferably a plurality, of rollers provided with recesses in their peripheral surfaces and mounted on the drive and trailing assemblies of a conveyor system. At least one side wall of each recess is angularly disposed relative to the central axes of the respective drive or trailing assemblies and the recesses are sized to receive therein a portion of the belt contacting the rollers. The bottom and side 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. Alternative embodiments employing polygonal rollers, alternately slotted rollers and rollers with "single sided" recesses are also provided.
