<p>In a line of presses (P1-P7), the pieces are transferred from one press to another by means of a plurality of programmable manipulator robots (R1-R6) interposed between the presses (P1-P7). The operating cycles of the manipulator robots are synchronised with those of the presses on the basis of the operating frequency of the first press (P1) at the input in the line, the operating cycles of the various machines in the line being derived from each other in a cascade process starting from the basic operating frequency. <IMAGE></p> |
