Abstract

Device for deforming hollow bodies using an inner high pressure comprises a two-part tool, an axial cylinder assigned to both sides, and a sealing stamp (20) formed as a steel stamp with a sealing edge (24) revolving on a support plate (22) in the transition to the foot region of the stamping heads (20a, 20b) with respect to the outer edge (23) of the support plate. The sealing edge has a material accumulation (26a, 26b) on each starting region of a groove (21).
