Zusammenfassung:The present invention thus relates to a device and to a method in which a can body (11) with cylindrical wall (12) and a neck section (13) of lower diameter can be manu­factured in one working stroke in one working direction (A). The device (10) has a drivable drawing ring (27) used for deep-drawing of a cup from a round, disk-like or plate ­like blank (32) in a first phase of the working stroke. Af­ter completion of this first phase the cup is drawn with the aid of an ironing mandrel (59) into an ironing channel (38) and formed into an ironed workpiece . Fi­nally, a stretch-forming mandrel (58) is moved out of a guide recess (60) of the ironing mandrel (59) and forms the neck section (13) or at least a part thereof in a stretch-drawing phase of the working stroke, in conjunction with a forming depression (48) of a domer (45). With the conclu­sion of the stretch-drawing phase, the working stroke is completed.
