Abstract
A method for hydraulic control of a toggle lever press in which the velocity of a driving piston rod is increased at least once in the working region of a press ram. The velocity of the press ram is thus kept relatively constant up to bottom dead center (or upper dead center) of the press ram. A toggle lever press has a control adapted for carrying out this method.
