ABSTRACT:
A control system for automatically counterbalancing the ram and tooling of a mechanical press by the measurement of strain in a press component or components subject to stress during operation of the press. The air pressure in one or more counterbalancing cylinders is varied to maintain balanced conditions in response to the strain measured at the top of the press cycle.
