 dazwischen liegenden Stempel bringen hingegen, wie aus der   Kräfteverteilung   nach Fig. 2 zu ersehen, ausser den senkrecht zur   Hülsenwandung   wirkenden Drücken noch tangential zur Hülse wirkende Ringbeanspruchungen hervor, durch welche ein Falten der Hülsenwandung verhindert wird. Um die   beim ersten Pressvorgang   an den Stosskänten der Stempel etwa auftretenden Grate zu beseitigen, wird   der ganze Pinael   um 180  gedreht. Da je zwei   gegenüberliegende Stempel.   wie oben erwähnt, verschieden breit sind, so kommen die entstandenen Grate nach dem Drehen

   bindende Ringnut ergeben.

 In contrast, as can be seen from the distribution of forces according to FIG. 2, in addition to the pressures acting perpendicular to the sleeve wall, the punches lying in between also produce annular stresses acting tangentially to the sleeve, which prevent the sleeve wall from folding. In order to remove any burrs that may appear on the punch bumpers during the first pressing process, the entire pinael is rotated by 180. There are two opposite stamps. As mentioned above, are of different widths, the resulting ridges come after turning
