Abstract
A flat wire conveyor belt comprising a plurality of tractive pickets, a plurality of connecting cross rods and a plurality of bar links is disclosed. Elongate openings in several of the wedge-shaped segments of each tractive picket adjacent the outer edge define a gap between the connecting rod and the adjacent surface of the openings during straight and lateral travel of the belt. Elongate openings in the remainder of wedge-shaped segments are in contact with the connecting rod in straight travel. Openings in the bar links define a gap between the connecting rod and an adjacent surface of the opening during straight travel of the belt. The remainder of the wedge-shaped segments thus carry a substantial tractive load during substantially straight travel of the belt, the bar links carry a substantial tractive load during travel around lateral curves, and the wedge-shaped segments adjacent the outer convex edge of the belt never carry a substantial tractive load.
