Abstract: A modular belt link which includes a link base having at least one hinge barrel for connecting the link to adjacent links. A side guard is fixed to the link base, and defines a non-planar wall having a bottom and top joined by sides. The wall is twisted relative to an axis of rotation extending through said top and bottom.

Abstract: A roller top conveyor chain assembly includes a first strand of conveyor chain formed from a plurality of first link assemblies. A second strand of conveyor chain is formed from a plurality of second link assemblies. The second strand of conveyor chain is substantially parallel to the first strand of conveyor chain for cooperatively conveying an object with the first strand of conveyor chain. A first roller support frame extends between one of the first link assemblies of the plurality of first link assemblies and one of the second link assemblies of the plurality of second link assemblies. The roller support frame includes a top wall having at least one upwardly opening cavity formed therein. A roller is rotatably mounted in the cavity for supporting the object being conveyed by the first and second strands of conveyor chain.
