ABSTRACT:
A load control system and tool arrangements are disclosed for controlling the shutheight and back-up load on a mechanical press tool in response to a monitored or measured parameter indicative of press tool force or part quality, which monitored parameter is communicated to a controller for determination of a control signal to control a means for regulating the press tool back-up load and shutheight without interrupting press operations. The control system is operable to control a single station or multi station press and can be installed on either an individual press tool or the bolster or slide.
