Abstract
A connecting rod unit is eccentrically supported on the drive shaft. The connecting rod unit is pivotally mounted via link members to double arm levers. Each double arm lever is pivotally mounted to a single arm lever. Furthermore, each single arm lever is coupled at its end remote from the double arm levers to a device for the adjusting of the height position of the ram. Each single arm lever supports a pressing column. These pressing columns are pivotally mounted to the ram. Accordingly, the structural members which transmit the driving force from the connecting rod unit to the pressing columns can be designed extremely stiff and with a minimal springiness. Also, all structural members located between the connecting rod unit and the ram, inclusive the ram, are designed in such a manner that no additional balancing forces for the vertical mass force balancing are needed.
