Abstract

A conveyor apparatus intermittently feeds a workpiece a fixed feed stroke in a conveyance direction, a plurality of workpiece pedestals spaced apart by the feed stroke in the conveyance direction support the workpiece until the moment of a subsequent feed operation, and a plurality of machines arranged near respective ones of the pedestals machine the workpiece supported by the pedestal. A walking beam in the conveyor apparatus for receiving the workpiece is moved upward, forward, downward and backward to raise the workpiece supported by one of the pedestals, convey the workpiece to a point above the next pedestal and then lower the workpiece so that the latter is supported by this next pedestal. The supporting position of the pedestal adjacent a machine having a first working area is at a level different from that of the pedestal adjacent a machine having a second working area not the same as the first working area, whereby the workpiece is set at a position which will not interfere with the working areas of machines other than the machine adjacent the pedestal supporting the workpiece.
