  • Tandem belt conveyor system
    Patent number: 5415274
    Abstract: A tandem belt conveyor system comprising an endless primary conveyor belt, an endless support conveyor belt and a synchronous drive for synchronously driving the primary and support conveyor belts. The primary conveyor belt is a flat wire belt having a carrier flight for transport of articles and a return flight. The support conveyor belt has a support flight for supporting the carrier flight of the primary conveyor belt, and a return flight. The support conveyor belt includes a pair of chains interconnected by transverse cross bars for supporting the primary conveyor belt. The synchronous drive includes an AC motor for driving one of the belts, a DC motor for driving the other belt, and a DC motor controller for controlling the AC and DC motors in master-slave relationship to synchronize the speeds of the belts.
