  • Rolling conveyor guide rail
    Publication number: 20040099511
    Abstract: A conveyor having a conveyor surface has along the lateral edges rotating guide elements. The rotating guide elements rotate on axes of rotation that lie in a plane that is substantially perpendicular to the conveyor surface, and also in a plane that is substantially perpendicular to the path of the conveyor. Each guide element has an outer circumferential surface that engages the lateral sides of a conveyed article on the conveyor surface to rotate the guide element, substantially eliminating sliding or rubbing contact between the conveyed article and the lateral guide elements.
