Abstract
A chain link conveyor belt carries lateral slats extending from the chain links, upon which are formed integral ribbed finger load carrying platform structure that interdigitates and overlaps their ribbed fingers with leading and trailing chain links in a conveyor belt. Wider belts are feasible when a parallel pair of spaced chains support the lateral slats extending horizontally from the chain links to the belt edges. The chain links are Y-shaped with elongated pivot rod slots in the leg to permit flexibility for laterally pivoting the belt around curved paths. Specially shaped structure on the slats near the belt edges supports long finger tip ribs of adjacent slats, thereby to strengthen the edge portions of the belt. The outermost fingers are reinforced to slide on guide rails. The trailing ribbed fingers diverge inwardly from the belt edges to avoid interference and fracture. In a typical embodiment, the belt modules are integrally molded of plastic with ribs about 1/16th inch thick and 1/4 inch high, slats about 1/4 inch thick and about 24 inches long, with two chain links having the slats disposed on their upper surface and being about 8 inches apart and 8 inches from the be…
