Zusammenfassung:	A can body (II) having a can base (13) and a can wall (14) is shaped by a wall ironing process starting with a blank (12). A drawing punch (15) moves the blank (12) through a wall ironing container (34) from an opening (35) to an exit (36). The edge (R) of the can body (II) opposite the can base (13) is separated using a cutting device (45), which has a force generating unit (46) arranged adjacent to the exit (36) and at least one cutting edge (26, 27) which can be arranged on the drawing punch (15). The force generating unit (46) generates a force (F) onto the can wall (14) edge (R) to be separated, whereby the edge is sheared off on the at least one cutting edge (26, 27). The can body (II) is located on the drawing punch (15) while the edge (R) is being separated.
