Abstract
A process and apparatus for the positive actuation of a weight compensating mechanism for a ram of a press accommodating a tool set. The process includes the detecting of at least one condition indicative of the changing of a tool set of the press, preventing working operation of the press in response to such detected condition, and then initiating operation of the weight compensating mechanism. The process also includes the enabling of the working operation of the press upon completion of the weight compensating operation. The apparatus for carrying out the process includes at least one signal generator for providing an output indicative of the changing of a tool set, a device for preventing working operation of the press in response to the detection of such condition and a control arrangement for initiating operation of the weight compensating mechanism in accordance with sensed conditions of the press.
