ABSTRACT:
A multi-section conveyor roller is engageable with a conveyor belt moveably mounted on a conveyor frame assembly. The roller includes a rotatable mounting hub connected to the conveyor frame assembly, and a plurality of adjacently disposed roller segments fixed to the mounting hub to form belt-engaging, curved outer wall surfaces. The outer wall surfaces are separated by a number of gaps, at least one of the gaps receiving rib structure provided on the conveyor belt for maintaining proper movement of the conveyor belt on the conveyor frame assembly.
