A modular conveyor belt (10) formed by rows (12A.12B) of belt modules (14) connected at hinge joints by non-circular hinge rods (30). Each rod has an arcuate outer face that forms a portion of a cylinder and extends circumf erentially over a first angle. An axial groove (32) is formed in the hinge rod opposite its outer face. Openings in hinge eyes (20,21) at opposite ends of the belt rows are sector-shaped. The openings (20) along a leading end of a row are shaped to receive a hinge rod snugly. The openings (21) along a trailing end of an adjacent row have similar radial dimensions, but extend circumferentially over a greater second angle. The hinge eyes of adjacent rows are interleaved to receive a rod and give the hinge joint a range of articulation. Protrusions (28) extending into the openings are received in the grooves in the rod to register it in the joint with limited vertical motion. |
