In a manufacturing method and apparatus for manufacturing sheet metal packets in punch-packeting technology with a round or oval iron cross section. laminations are punched from a ribbon and are provided with depressions at one side and with elevations at the other side that coincide with the depressions and lie opposite them, with the elevations being in the form of at least two circular nipples being pressed into the depressions upon assembly of each packet. In one lamination per packet, serving as a separating lamination, cylindrical holes are punched instead of the depressions, the nipples of the neighboring lamination engaging into these holes. Laminations are thereby punched from the strip that respectively exhibit different outside contours, particularly different widths, and are joined with one another to form a packet that has a cross-section that is at least partially round, by virtue of the sheet metal packet having graduated edges.
