A press product line of presses for massive forming has toggle lever transmissions for driving a slide. Different slide strokes and path-time characteristic curves of the slide movement are achieved starting with uniform blank components. The critical dimensions, i.e., the bearing locations of the toggle lever transmission on the machine frame, are constant within the entire press product line, so that at least to that extent, uniform machine frames can be used. Specially desired path-time progressions are achieved through appropriate fine machining of the blank components (eccentric, connecting rod and link bars).
