ABSTRACT:
In a control circuit for a transfer device including feed bars movable along two or three axes and servo-actuators respectively provided for driving the feed bars in stroke-forming movements along the axes, there are provided a stroke signal generator for generating a stroke defining signal separately from press movement and press control device for controlling the operation of a press. Based on the output signal from the stroke signal generator, the press control delivers press starting and stopping instructions at appropriate instants not interfere with the movements of the feed bars for initiating press operations of an intermittent nature.
