Description
Der Gegenstand der Erfindung ist ein Verfahren zur Herstellung elektrischer Glühlampen auf maschinellem Wege. Das wiederholte Erhitzen des Glasrohres, aus welchem die Glühlampenglocke geblasen wird, und zwar einmal zwecks Verschmelzung mit dem Füßchen und hierauf zwecks Aufblasens der Glühlampenglocke, gibt leicht zu einer Beschädigung des Füßchens oder des LeuchtkörpersThe subject of the invention is a method for producing electric incandescent lamps by machine. The repeated heating of the glass tube from which the incandescent lamp bell is blown, namely once for the purpose of merging with the foot and then for the purpose of inflating the bulb, easily damages the foot or the filament
ίο Anlaß. Durch das Verfahren gemäß vorliegender Erfindung wird dieser Übelstand dadurch beseitigt, daß das Aufblasen des Glasrohres zur Glocke unmittelbar nach dem Einschmelzen des Füßchens erfolgt, noch ehe die Schmelzstelle wesentlich abgekühlt ist. Zur Ausführung des Verfahrens mittels einer Maschine erweist es sich als zweckmäßig, jene -Klemmen; die als Halte- oder Mitnehmerorgane für das Glasrohr bei seiner Rotation dienen, als Hälften einer geteilten Glockenblasform auszubilden, in diese Form den erhitzten Glasrohrteil einzuführen und zur Glocke aufzublasen.ίο occasion. By the method according to the present Invention, this drawback is eliminated in that the inflation of the glass tube to the bell immediately after the foot has melted, before the melting point has cooled down significantly. To the Execution of the method by means of a machine, it proves to be expedient to those -Clamps; as holding or driving organs serve for the glass tube as it rotates, as halves of a split bell-shaped blow mold train to introduce the heated glass tube part in this form and to the bell to inflate.
In der Zeichnung sind drei Stadien des geschilderten Verfahrens dargestellt.The drawing shows three stages of the process described.
