  "abstract": "A modular plastic conveyor belt constructed of injection-molded belt modules having narrowed portions either above or below rod holes in hinge elements. The narrowed portions are formed by a restricted-flow region in an injection-mold cavity that ensures that weld lines in the hinge elements are angled off the pull line of the conveyor belt.",
