  • Patent number: 11767171
    Abstract: An apparatus for conveying an object in a conveying direction includes a conveyor comprised of a plurality of modular links adapted for interconnecting to form a chain. At least one of the links comprises a rounded upper portion forming an apical region for contacting and supporting the article for conveyance along at least a forward run in the conveying direction. The at least one link further including a forwardly projecting portion associated with a first transverse connector forming a part of the upper portion and a rearwardly projecting portion associated with a second transverse connector forming part of the upper portion. The first and second connectors may be staggered in the conveying direction and a direction transverse to the conveying direction. Further aspects pertain to a link with an apical engaging structure, and a sprocket with a removable tooth.
