ABSTRACT:
An article carrying chain includes a plurality of interconnected molded plastic chain link assemblies each having a planar top plate. The chain link assemblies are interconnected so as to permit articulation between adjacent links around orthogonal axes. The potential for wear or breakage between adjacent links is reduced by beveling at least one of the mating edges between the top plates of adjacent links. Product kick-up is avoided by rounding the upper surface of each top plate along its leading and trailing edges. The underside of each link assembly is shaped so as to be engageable by either side of a sprocket tooth to thereby permit the sprocket to drive the chain in either of two directions. A plurality of upper and lower tabs formed along the lower portions of the chain link assemblies function to stabilize the chain relative to a pair of glide rails while permitting free removal of the chain link assemblies from the guide rails.
