A device for processing a plate element () has a rotable hub (), two tools (), mounted on the hub () to process the element () when each tool is in a respective processing position; a drive to rotate the hub () and the two tools (); a rotatable counter-tool (). The rotation (R) of the hub () varies during a rotation cycle of the hub (), and includes two constant speed phases during each of which one of the two tools () is, in succession, in the processing position; and at least one phase with each of the two tools () in an intermediate position between the respective processing positions, so as to achieve a front lateral processing position and a rear lateral processing position on the element ().
