In order to hold the longitudinal edges (12, 14) of a can body (10) which are to be butt-welded together contiguous with one another on the way to a welding apparatus (52), the can body (10) is moved past a magnet (40) by means of which the longitudinal edges (12, 14) are magnetized with opposite polarity. The two poles (NS, SN) of the magnet (40) each have a supporting surface (42, 44) for a conveyor belt (36) which conveys can bodies (10) one behind the other from a guide member (22) to the welding apparatus (52). |
