摘要：
A device for processing a plate element (35) has a rotable hub (52), two tools (57, 58), mounted on the hub (52) to process the element (35) when each tool is in a respective processing position; a drive to rotate the hub (52) and the two tools (57, 58); a rotatable counter-tool (64). The rotation (R) of the hub (52) varies during a rotation cycle of the hub (52), and includes two constant speed phases during each of which one of the two tools (57, 58) is, in succession, in the processing position; and at least one phase with each of the two tools (57, 58) 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 (35).
