Abstract
A tractive link member for connecting adjacent rods of an endless conveyor belt and for assuming tractive load. The links include a substantially flat piece of metal formed into a general U-shape with a pair of spaced leg portions joined by a connecting portion. Each of the leg portions have at least one hole for receiving adjacent rods of a conveyor belt. The substantially flat piece of metal along the length of the connecting portion has both a first thickness area and a second, reduced thickness area. The reduced thickness area is a compressed work-hardened area of the metal. The reduced thickness area in the connecting portion can form a curved bearing surface against which a rod can bear. A middle section of the link leg can diverge outwardly from an inner section of the link leg to form a single offset between the slotted portions of the link.
