ABSTRACT:
A production line for working on a succession of workpieces has a transporter or conveyor defining a longitudinal path for carrying and displacing the succession of workpieces in longitudinal stop-and-go steps through a succession of stations generally longitudinally equispaced along the path, respective machines at the stations for lifting the workpieces off the conveyor and working on the workpieces as same are stopped between transport steps, and a lifter at at least one of the stations for raising the workpieces thereof off the conveyor and holding them clear thereof between transport steps. Thus some of the stations are merely holding or nonworking stations where nothing is done to the workpieces. The machines at this or these stations can be adapted to work only on other types of workpieces mixed in with the production run, or only on certain of the workpieces for custom work.
