ABSTRACT:
A press and press method wherein an article is shaped by displacing a tool thereagainst in a plurality of time-spaced main strokes separated by intervals in which the energy for the main strokes is stored in a force-storing element such as a rod under tension and during these intervals, the tool continues to be advanced against the article by an auxiliary motor. The apparatus utilizes a lever pivotally connected to a support, to the force-storing element and to the tool. The main drive motor acts on this lever.
