ABSTRACT:
In one embodiment, the invention comprises at least one and preferably a plurality, of rollers provided with recesses which are mounted on the drive and trailing assemblies of a conveyor system. The recesses of each roller include abutment surfaces angularly disposed relative to the central axes of their respective drive or trailing assemblies and are sized to receive, support and align the belt. Alternative embodiments employing polygonal rollers, rollers with a single wall forming two angled abutment surfaces and rollers with support surfaces disposed to receive multiple belt segments are also provided. The rollers, in addition, may include sets of the recesses distributed in circumferential rows about their periphery, including an odd number of sets of recesses to reduce wear on 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.
