<p>A drive mechanism (10) drives a slide (4) in a cycle along a centerline. The slide includes a press center symmetrical with a frame centerline. A frame includes (103) guides aligned with the press center (P) and the slide to eliminate rotative force upon the slide during operation and increase precision. The drive mechanism includes a first (15) and a second (17) link coupling a main gear (14) to a crank shaft (13) to lower a slide speed near a bottom dead center position and increase a slide speed near a top dead center thereby increasing a press force at the bottom dead center position and speeding cycle turn. <IMAGE></p>
