Abstract
The instant invention provides a compact sprocket type drive unit which can be manufactured from reduced number of parts. The invention further provides a method by which multiple drive units for a single conveyor or synchronization between separate conveyors can be achieved without the necessity of costly electrical and mechanical control devices. Because the present invention provides automatically synchronized multiple conveyors, the transfer of work from one conveyor to another can be achieved with vast savings in cost of conveyor design, manufacturing, and installation.
