ABSTRACT:
A spiral conveyor belt adapted to turn on a radius. The spiral conveyor belt comprises a plurality of link assemblies with each of the link assemblies having a plurality of forward link ends and a plurality of rearward link ends. Each link assembly is positioned near one of the other link assemblies with the forward link ends on one of the link assemblies being disposed near the rearward link ends on the other link assembly. A link shaft is disposed through the forward link ends and the rearward link ends of the adjacent link assemblies for interconnecting the link assemblies to form the spiral conveyor belt. The forward link ends and the rearward link ends on each of the link assemblies near at least a first end of the link assembly are spaced a distance apart and connected by connecting members whereby the forward link ends and the rearward link ends and the connecting members connected thereto are collapsible generally toward each other or expandable generally away from each other as the spiral conveyor belt is turned on the radius. Each of the link shafts is tapered at least near the first end thereof to permit movement of the tapered portion of the link shaft in shaft openings in the forward and rearward link ends as the spiral conveyor belt is turned on a radius.
