Abstract
The balancing weights are hingedly mounted at their lower ends to link rods. These link rods are hingedly mounted to an extended section of first rods. At opposite ends the balancing weights are hingedly mounted to reversing levers that in turn are hingedly mounted to second rods. The first rods and the second rods are supported on a common eccentric sleeve. Accordingly, the drive of the balancing weights does not come from structural members of the machine which are directly mounted to the ram. Accordingly, no mass forces and oscillations of the balancing weights and of the structures driving same can be transmitted onto the ram. Conclusively, the moving sequence of the ram and accordingly the cutting or embossing action is no longer influenced detrimentally such that the quality of a respective product produced is improved.
