Zusatz zum Patente Λί 92657 vom 5. Februar i<Addendum to the patent Λί 92657 from February 5th i <
Die Einrichtungen, welche in dem D. R. P. Nr. 92657 zur Ausführung des in dem D. R. P. Nr. 92656 beschriebenen Verfahrens zur Herstellung von Glastafeln, Walzen, Röhren und dergl. beschrieben sind, erhalten nach vorliegender Erfindung eine Abänderung, durch welche sich für die gleichmäfsige Durchführung des Ziehverfahrens erhebliche Vortheile ergeben. Es ist in dem D. R. P. Nr. 92657 ein Gefäfs a angegeben, dessen Boden den formgebenden Spalt bildet, in welches Gefäfs die flüssige Glasmasse aus dem Wannenofen hineinfliefst, dasselbe anfüllt und dann aus dem formgebenden Spalt heraustritt, um dem Ziehverfahren zu unterliegen.The devices, which are described in the DRP No. 92657 for the execution of the process for the production of glass sheets, rollers, tubes and the like described in the DRP No. 92656, receive a modification according to the present invention, by which the uniform execution of the Drawing process result in considerable advantages. DRP No. 92657 specifies a vessel a , the bottom of which forms the shaping gap, into which vessel the liquid glass mass flows from the furnace, fills it and then emerges from the shaping gap in order to be subjected to the drawing process.
An Stelle des Gefäfses α soll jetzt ein Raum treten, welcher in dem Wannenofen direct oder in einem Anbau des Wannenofens angeordnet ist und dessen Boden den formgebenden Spalt enthält. Die Ränder dieses Spaltes können durch metallene Röhren, Balken oder Leisten gebildet werden, die durch ihren Abstand von einander den formgebenden Spalt begrenzen. Der Raum selbst kann von ganz geringer Höhe sein, so dafs dann der Stand der Glasmasse über dem Spalt ebenfalls nur geringe Höhe hat.Instead of the vessel α, there should now be a space which is arranged directly in the tub furnace or in an extension of the tub furnace and the bottom of which contains the shaping gap. The edges of this gap can be formed by metal tubes, bars or strips, which delimit the shaping gap due to their distance from one another. The space itself can be of a very small height, so that the level of the glass mass above the gap also has only a small height.
Die den Spalt begrenzenden Balken und Leisten werden am besten wie die ebenfalls zu diesem Zwecke zu verwendenden Röhren hohl gebildet, um durch Wassercirculation gegen Einwirkung der Hitze gekühlt werden zu können. Solche Kühlvorrichtungen sind bekannt und werden bei Ausflufsöffnungen für glühende Massen verwendet. Im vorliegenden Falle bewirkt die Kühlung ein Ueberziehen der Spaltränder mit erstarrender Glasmasse, die die directe Einwirkung der Hitze auf diese Ränder verhindert. Zwischen diesem erstarrten Ueberzuge läuft die zähflüssige Masse im Spalte nieder, und empfiehlt es sich, unter dem Spalte zu beiden Seiten Düsen anzubringen, durch die eine oder mehrere Gasflammen gegen die Mittelpartie des auslaufenden Glasflusses gerichtet werden, um denselben fortdauernd in gleichmäfsiger, zum Ausflusse geeigneter Zähigkeit zu erhalten. Die einwirkenden Stichflammen können nach Bedarf regulirt werden.The joists and ledges delimiting the gap are best like that too Tubes to be used for this purpose are formed hollow to counteract by water circulation To be cooled by exposure to heat. Such cooling devices are known and are used for outflow openings for glowing masses. In the present case effected the cooling, a coating of the edges of the gap with solidifying glass mass, which is the direct effect which prevents heat on these edges. Between these solidified coatings the viscous mass settles in the column, and it is advisable to under the column on both sides To attach nozzles, through which one or more gas flames against the central part of the expiring glass flow are directed to the same continuously in uniform, to the To obtain outflows of suitable tenacity. The acting flames can be used as required be regulated.
Zwichen diesen Flammen geht die zähflüssige Glasmasse nieder, wird erfafst und in die durch den Spalt gegebene Form zu Flächen oder Hohlkörpern ausgezogen. Aus den Figuren der beiliegenden Zeichnung ergiebt sich, dafs die Glasmasse aus dem Schmelzraum, gegebenenfalls unter einer Scheidewand α und über eine Brücke b geführt, in einen zwischen der Wannenwand und der Ofenwand gebildeten Raum c eintritt und direct durch den SpaltBetween these flames the viscous glass mass goes down, is captured and drawn into the shape given by the gap to form surfaces or hollow bodies. The figures in the accompanying drawing show that the glass mass from the melting chamber, possibly passed under a partition α and over a bridge b , enters a space c formed between the furnace wall and the furnace wall and directly through the gap
ausfliefst, der durch Röhren, Balken oder Leisten d begrenzt ist.· which is limited by tubes, beams or strips d.
Die neue Einrichtung führt nicht allein den Vortheil der Ersparung in der Beschaffung von besonderen Gefäfsen und etwa nöthig werdender Auswechselung derselben herbei, sondern gewährt auch noch den Vortheil. der schnelleren Beeinflussung und Regelung der Zähigkeit der Glasmasse durch das bedeutend niedrigere Niveau der Glasmasse über dem Spalt im Vergleich mit der Höhe und dem dadurch bedingten Druck der Masse über dem Spalte in besonderen Gefäfsen.The new facility not only has the advantage of saving in the procurement of special vessels and any necessary replacement of them, but granted also the advantage. the faster influencing and regulation of the toughness of the Glass mass by the significantly lower level of glass mass above the gap in comparison with the height and the resulting pressure of the mass above the crevice in special vessels.
