<p>A control system for a press having a synchronized feed mechanism includes a first drive motor for the press, a second drive motor for the feed mechanism, means responsive to the positions of the press and the feed mechanism for producing an output signal representing any change in the positional relationship between the press and the feed mechanism, control means responsive to the output signal for controlling the speed of the drive motor for the feed mechanism, and means for adjusting the control means to simulate a change in the press position and thereby effect a movement of the feed mechanism. An interlock is responsive to adjustments of the control means for enabling the startup of the press only when the control means is in a preselected position representing a desired positional relationship between the press and the feed mechanism.</p> |
