Description

Verfahren zur Herstetlung von Hohlkörpern. Bei dem bekannten Verfahren zur Herstellung von Hohlkörpern mit durchbrochenen Verzierungen konnten keine Hohlkörper mit durchbrochenen Verzierungen hergestellt werden, bei welchen die Verzierungen in einem so spitzen Winkel ausliefen, daß das Material am Ende des spitzen Winkels dicht zusammentritt, da Schnittwerkzeuge zum Durchbrechen solcher Verzierungen gar nicht ausführbar sind und gegebenenfalls die Stempel der Werkzeuge schon beim Durchbrechen einiger Verzierungen abgenutzt wären.Process for the production of hollow bodies. In the known method Hollow bodies could not be used to produce hollow bodies with openwork decorations are made with openwork decorations, in which the decorations ran out at such an acute angle that the material was at the end of the acute angle close together, since cutting tools for breaking through such decorations even are not executable and possibly the stamp of the tools already when breaking through some decorations would be worn out.

Durch die vorliegende Erfindung wird es ermöglicht, Hohlkörper mit solch durchbrochenen Verzierungen herzustellen, indem ein bandartiger Streifen a auf einer Längsseite ohne Abfall durch Einschnitte c in kammartige Zinken b getrennt wird, wie dies Abb. i darstellt, und dann in .die Form des Hohlkörpers zusammengebogen wird, so daB die Enden der Kammzinken b am Boden dicht zusammenbleiben, wie dies als Ausführungsform in Abb. 2 dargestellt ist. Es kann auch ein bandartiger Streifen a (Abb. 3) kammartig ausgeschnitten und dann irr die Form des Hohlkörpers zusammengebogen werden, so daß die Enden der Kammzinken a1 (Abb. q.) am Boden dicht nebeneinanderstehen.The present invention makes it possible to use hollow bodies to produce such openwork decorations by making a ribbon-like strip a separated on one long side without waste by incisions c in comb-like prongs b is, as shown in Fig. i, and then bent into .die shape of the hollow body so that the ends of the comb teeth b stay close together at the bottom, like this is shown as an embodiment in Fig. 2. It can also be a ribbon-like strip a (Fig. 3) cut out like a comb and then bent into the shape of the hollow body so that the ends of the comb teeth a1 (Fig. q.) are close to each other on the ground.

Material, Größe und Form der herzustellenden Hohlkörper werden zweckentsprechend gewählt.The material, size and shape of the hollow bodies to be produced are appropriate chosen.
