Abstract
A double action mechanical press, especially for cupping operations in which an outer slide is provided within which an inner slide is reciprocally mounted on a common crankshaft. According to the present invention, a single dynamic balancer, out of phase from both the inner and outer slides, is provided on the crankshaft in order to counterbalance the inertial forces generated by the inner and outer slides during press operation.
