Description

Verfahren zum Ziehen von Glasröhren Gegenstand der Erfindung ist ein Verfahren zum Ziehen von Glasröhren, bei welchem der zylinderförmigen, aus der Bodenöffnung eines Behälters austretenden Masse aus geschmolzenem Glas mit Hilfe eines schief in das Innere der Glasmasse eingeführten und gegen die Innenwand gerichteten Luftstroms eine kreisende Bewegung erteilt wird. Hierdurch wird eine gleichmäßigere Abkühlung des Glases hervorgerufen.A method for drawing glass tubes Method for drawing glass tubes, in which the cylindrical, from the bottom opening a container leaking mass of molten glass with the help of a crooked air flow introduced into the interior of the glass mass and directed against the inner wall a circular motion is given. This results in a more even cooling of the glass.

Abb. i ist ein Schnitt durch eine Vorrichtung zur Ausführung des Verfahrens. Abb.2 ist ein Schnitt durch das Rohr nach Linie 2-2 der Abb. i.Fig. I is a section through an apparatus for carrying out the method. Fig.2 is a section through the pipe along line 2-2 of Fig. I.

Die GlasmasseA, die in dem Ofen 24 geschmolzen ist, fließt durch ihr Eigengewicht durch die Austrittsöffnung B. In der Achse der Öffnung befindet sich ein Rohr oder Dorn 9, das in eine kegelförmige Erweiterung i i ausläuft, die ein Absperrventil für die Öffnung B bildet, wenn man das Rohr 9 anhebt. In das Rohr 9 wird Luft unter Druck eingeführt. Die Luft mündet in die rohrförmige Glasmasse P am unteren Ende des Dornes durch eine Leitung i ia ein, so daß die Luft im Winkel gegen die Glasmasse strömt und ihr dadurch eine kreisende Bewegung erteilt wird. Die Leitung i ia kann beispielsweise eine schraubenförmige Gestalt besitzen, wie in Abb.2 dargestellt ist.The glass mass A melted in the furnace 24 flows through it Dead weight through the outlet opening B. Located in the axis of the opening a tube or mandrel 9 which terminates in a conical extension i i, which is a Shut-off valve for opening B forms when the pipe 9 is lifted. In the pipe 9 air is introduced under pressure. The air flows into the tubular glass mass P at the bottom of the mandrel through a conduit i ia a so that the air is at an angle flows against the glass mass, giving it a circular motion. The line i ia can for example have a helical shape, such as is shown in Fig.2.
