  • Patent number: 9174803
    Abstract: A conveyor system including a train of carrier plates arranged for movement along a conveyor path which possesses either rightward turns or leftward turns and each carrier plate defines a leading edge and a trailing edge. Each of the leading and trailing edges has an outer portion which is disposed adjacent a side of the carrier plate opposite the direction of turn of the conveyor path and an inner portion. Each carrier plate is pivotally mounted upon an endless drive member at a location along the carrier plate which is disposed between the leading and trailing edges of the plate, and is shaped so that the outer portion of each of its leading and trailing edges is longer than the inner portion of its leading and trailing edges. Gap plates cover any gap between two sequential conveyor plates as the train is moved through non-linear sections of the conveyor path.
