An apparatus for forming socket and bead configurations in tubular bodies including a divided external mold, an expanding mandrel having two parts between which a sizing ring is provided. The sizing ring is rotatably mounted on a slide element supported in a rotatable guide member. By setting the guide member into rotation the sizing ring scribes a circular path about the central axis of the expanding mandrel. A radial-displacing cylinder is provided for shifting the slide element and thus sizing ring 3 in the radial direction. Also disclosed is the method resulting from the use of the above apparatus.
