  Verfahren zum Ausschneiden von kreisrunden Öffnungen aus Glasgegenständen mittels der Stichflamme. 



   Ein bekanntes Verfahren, Hohlglaskörper von der Glaspfeife abzutrennen, beruht darin, an derjenigen Stelle, an welcher die Abtrennung erfolgen soll,   Stirhtlammen   auf das Glas einwirken zu lassen, solange sich dasselbe in formfähigem Zustande befindet. Dabei kann entweder die Schnittlinie am Brenner vorbei, oder der Brenner längs der Schnittlinie geführt werden. 



   Die Erfindung betrifft nun das Ausschneiden kreisrunder Öffnungen aus   Glasgegenständen   nach diesem Verfahren und bezweckt, den bei   der Stichflammenbehandlung   entstehenden Schmelzwulst zu verflachen   und   gleichmässig am Rand der Öffnungen zu verteilen, um eine be-   sondere Nachbearbeitung   des Lochrandes entbehrlich zu machen. 



   Das neue Verfahren besteht darin, das   Arbeitsstück   gegen einen   feststehenden Stich-   flammen brenner um eine durch den Mittelpunkt des Kreisausschnittes gehende Achse zu drehen, nach dem vollendeten Ausschneiden der Einwirkung der Stichflamme zu entziehen und   fürt   so gesteigerter Geschwindigkeit weiterzudrehen. dass durch die Fliehkraft die beabsichtigte

   Die gleichmässige Verteilung und Verflachung   des Schmelzwulstes   unter der Einwirkung der Fliehkraft beruht darauf, dass die weiter von den Oberflachen des Glases entfernten Teilchen des hohen flüssigen Wulstes bei ihrem Bestreben, nach aussen zu flichen, einen geringeren Widerstand finden als   die näher dem inneren Rand   der Öffnung gelegenen Teilchen, hinter denen sich grössere und starrere   Gasmassen     befinden. Die äusseren Teilchen   des Wulstes können also grössere Wege zurücklegen, als die inneren,   wodurch der gewünschte Ausgleich   der    Wulst masse   herbei-

  Method for cutting out circular openings from glass objects using a jet flame.



   A known method of separating hollow glass bodies from the glass pipe is based on letting forehead lambs act on the glass at the point where the separation is to take place, as long as the same is in a formable state. The cutting line can either pass the burner or the burner can be guided along the cutting line.



   The invention now relates to the cutting out of circular openings from glass objects by this method and aims to flatten the molten bead that occurs during the jet flame treatment and to distribute it evenly on the edge of the openings in order to make special post-processing of the edge of the hole unnecessary.



   The new process consists in rotating the work piece against a stationary jet flame burner around an axis going through the center of the circular segment, after the cutting out of the effect of the jet flame withdrawn and thus increasing the speed further. that by centrifugal force the intended

 union production of holes with the jet flame, which could previously only be removed by special reworking of the cooled glass object.



   The even distribution and flattening of the melt bead under the action of centrifugal force is based on the fact that the particles of the high liquid bead further away from the surface of the glass encounter less resistance in their attempt to flow outwards than those closer to the inner edge of the opening located particles behind which there are larger and more rigid gas masses. The outer particles of the bead can cover longer distances than the inner ones, whereby the desired balancing of the bead mass is achieved.
