<p>A workpiece handling system especially for carrying out computer-controlled welding operations has a workpiece table which is rotatable between indexed stations in one direction and a coaxially-mounted support for work-performing apparatus which is rotatable in both directions, either with or contra to the workpiece table. While workpieces are being loaded and unloaded at one station, work can be performed at or during indexed movement between other stations, the work-performing apparatus then rotating contra to the workpiece table to find the next workpiece to be worked on.</p> |
