Abstract
A method and an apparatus for manufacturing a workpiece in plurality of manufacturing steps with small time losses between successive manufacturing steps, which utilizes a small number of manufacturing machines, according to which the manufacturing machines and the transferring machines are controlled such that while one manufacturing step is being applied by one manufacturing machine and then the workpiece is being transferred by the transferring machine from that one manufacturing machine to another manufacturing machine for applying a next manufacturing step to the workpiece, the another manufacturing machine is prepare for the next manufacturing step by placing an appropriate one of the manufacturing press dies under the ram of the press machine of the another manufacturing machine by intermittently moving the plurality of manufacturing press dies.
