Abstract: An apparatus for transporting a plurality of containers through a plurality of work stations including at least two conveyor assemblies, each conveyor assembly being adapted to sequentially convey at least one group of containers therealong in a row from one work station to another. The apparatus further includes a plurality of holder assemblies for holding the containers, some of the holder assemblies being associated with one of the conveyor assemblies and some of the holder assemblies being associated with the other conveyor assembly. The holder assemblies are located on the respective conveyor assemblies such that the plurality of containers are positioned adjacent to each other as they move through the plurality of work stations. A computer control system is programmable to control the coordinated operation of the conveyor assemblies so as to move such conveyor assemblies at different cycles of movement as the containers move through the work stations.
