Unterhalb der Stempel 19 befinden sich in der Matrize senkrecht verschiebbare Ringe 26, welche ebenfalls von einer (nicht gezeichneten) Feder beeinflusst werden ; diese Ringe dienen zum Halten der Platten und als Auswerfer. Innerhalb des beweglichen Unterstützungsringes 26 ist ein fixer Unterstützungsblock 261 angeordnet, welche beide mit den Stempeln 19, 20 derart zusammenwirken, dass die ausgeschnittene zweite Plombenhälfte 11 durch den fixen Block 261 und Stempel 20 gepresst und durch den Ring 26 und hohlen Stempel 19 an den Rändern 14 umgebogen wird, worauf die gepressten Stücke aus der Matrize durch die hohlen zylindrischen Stempel 19 ausgehoben und, sobald die letzteren am Hubende anlangen, durch die von den Hohlstempeln umschlossenen, vollen Stempel 20 ausgeworfen werden.
Damit die fertigen Stücke nicht auf die Matrize zurückfallen, erteilt man dem Ständer der Presse eine gewisse Neigung.
Obwohl das beschriebene Werkzeug die Erzeugung von zwei Plomben gleichzeitig gestattet, kann die Anordnung der Stempel auch derart getroffen sein, dass nur eine Plombe bei jedem Vorschub des Streifens ausgeschnitten und gestanzt wird.

Below the punch 19 are vertically displaceable rings 26 in the die, which are also influenced by a spring (not shown); these rings are used to hold the plates and as an ejector. A fixed support block 261 is arranged within the movable support ring 26, both of which interact with the punches 19, 20 in such a way that the cut-out second seal half 11 is pressed through the fixed block 261 and punch 20 and through the ring 26 and hollow punches 19 at the edges 14 is bent, whereupon the pressed pieces are lifted out of the die through the hollow cylindrical punches 19 and, as soon as the latter reach the end of the stroke, are ejected through the full punches 20 enclosed by the hollow punches.
So that the finished pieces do not fall back onto the die, the press stand is given a certain incline.
Although the tool described allows the production of two seals at the same time, the arrangement of the stamps can also be made such that only one seal is cut out and punched with each advance of the strip.
