A profiled metal strip for a diaphragm bellows is made from a strip material having at least one border which is subjected to reverse bending. Such a metal strip is wound to produce a diaphragm bellows, with abutting borders of neighboring turns being connected with one another by a material joint, such as a welding seam.
