ABSTRACT:
A mechanical press has an elevated welding station and a workpiece conveyor extending through the press at a level spaced below the welding station. A lift mechanism below the conveyor is designed to elevate the platen with a straight line vertical motion in two successive steps to first engage a workpiece on the conveyor and then elevate the workpiece to the welding station. Thereafter the lift mechanism lowers the platen with a straight line vertical motion in two successive steps to first deposit the welded workpiece on the conveyor and then recede to its starting position. The drive for the lift mechanism gradually accelerates the platen at the beginning of each step and gradually decelerates it to a near zero velocity at the end of each step.
