Abstract
A shiftable workpiece transfer apparatus for transferring a workpiece to a press while simultaneously shifting the workpiece centerline. Such a transfer apparatus includes cooperating workpiece transfer tables, the movement of which is directed by respective guide rails. A first workpiece transfer table is directed along a path that is substantially parallel to the centerline of the press line. The second workpiece transfer table is directed along a path that is skewed with respect to the centerline of the press line by an amount sufficient to produce a desired shift of the workpiece centerline. As the second transfer table moves along the skewed guide rail and toward the first transfer table, the workpiece is automatically moved across the surface of the first transfer table to a desired centerline offset point.
