Abstract

Bodies of revolution are produced having at least one peripheral groove whose width decreases towards the floor of the groove by rotating a blank 9 about its longitudinal axis while a pressure which exceeds the yield point of the material of the blank is locally applied. To avoid excessive hardening of the blank material during shaping, pressure on the blank is reduced from a maximum corresponding to the width of the groove at the peripheral surface of the blank, to the width of the floor of the groove, in accordance with the progressing depth of impression X1 to X5. The blank is rolled between ribs on a central roller (12, Figure 18) and ribs 7 and 8 on die segments 2 to 6. The initial portion of each rib is axially wide but radially shallow and the radial height of the ribs increase while their width decreases. <IMAGE>
