ABSTRACT:
A workpiece transfer apparatus is provided wherein an overhead transfer rail is arranged along and over a line of machine tools performing the same machining function, for guiding a plurality of pairs of workpiece carriers associated respectively with the machine tools. Each pair of the workpiece carriers are movable for respectively performing the loading of a workpiece into and the unloading of the same from an associated one of the machine tools. One of each pair of the workpiece carriers is also movable for transferring a workpiece from a support station disposed before the associated one of the machine tools directly to another support station disposed behind the associated one of the machine tools so that the same is bypassed by any workpiece to be machined in a succeeding one of the machine tools or having been machined in a preceding one of the machine tools.
