In a straight side press having a bed, a reciprocal slide, a power drive for the slide and apparatus for feeding a stock strip onto the dies, and a conventional die set, the improvement of modifying the press to function as a transfer press by replacing the conventional die set with a transfer unit. The unit includes a plurality of longitudinally spaced sequential dies upon a lower die shoe having a sub-plate secured to the bed to define a series of stations. A plurality of corresponding spaced sequential punches are mounted upon an upper die shoe and secured to the slide. A pair of slide bars are reciprocally mounted upon the lower die shoe outwardly of the dies mounting pairs of opposed workpiece gripping fingers adapted for engagement with the respective workpieces at each station. The transfer unit includes a slide bar translator mounted upon the sub-plate and has a reciprocal end plate connected to the slide bars for intermittently transferring the workpieces from station to station. The translator is adapted for alternately moving the slide bars towards and away from each other. The method of modifying a straight side press includes removal of the die set therefrom and replacing it with a transfer unit, so that the modified straight side press functions as a transfer press.
