KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es ist bekannt, daß das Motzen von Glasmasse unmittelbar an Eisenflächen wegen der wärmeentziehenden Eigenschaft des Eisens nicht vorteilhaft ist.It is known that the moth of glass mass directly on iron surfaces because of the heat-extracting property of iron is not beneficial.
S Bei der Vorbereitung der Glasmasse für die Mundbläserei benutzt man daher vorzugsweise Motzen, die ganz aus Holz oder aus Eisen mit einer Einlage von Holzstoff bestehen. Dabei benetzt man die InnenflächenS It is therefore preferable to use when preparing the glass mass for oral blowing Motzen made entirely of wood or of iron with an insert of wood pulp exist. In doing so, the inner surfaces are wetted
ίο der Motzen mit Wasser, um sie vor dem Verbrennen zu schützen. Durch die Berührung der heißen Glasmasse mit den nassen Flächen entwickelt sich Dampf. Dieser erleichtert das Abwälzen der Glasmasse in der Motze und verhindert gleichzeitig ein Abdrücken von Unregelmäßigkeiten in der Struktur der Holz- oder Holzstofflächen an der Oberfläche des weichen Glases. Diese Verhältnisse sind auch schon beim Walzen von Glas ausgenutzt worden, indem man Glas zwischen porösen, ' mit Wasser angefeuchteten Flächen ausgewalzt hat.ίο the moths with water to clean them before Protect from burning. When the hot glass mass comes into contact with the wet surfaces, steam is generated. This makes it easier the rolling of the glass mass in the moth and at the same time prevents it from being pushed off of irregularities in the structure of the wood or wood pulp surfaces the surface of the soft glass. These ratios are already in place with rolling of glass has been exploited by placing glass between porous, 'moistened with water Has rolled out surfaces.
Gegenstand vorliegender Erfindung ist, diesen Vorgang für das bekannte mechanische Blasverfahren nutzbar zu machen, bei welchem Glasmasse in einer Vorform vorgepreßt und in einer Fertigform ausgeblasen wird. Man benutzt hierzu im wesentlichen eiserne Vorpreßformen, die aber ebenfalls .,den Nachteil besitzen, daß sie der Glasmasse rasch und viel Wärme -entziehen. Es ist zwar schon versucht worden, einzelne Teile dieser Vorpreßformen aus schlecht wärmeleitenden Stoffen herzustellen oder die Leitung durch Hinterfüllung der Formenwandungen mit derartigen Stoffen zu vermindern. Die Haltbarkeit solcher Formenteile bei unmittelbarer Berührung der heißen Glasmasse mit den schlecht, wärmeleitenden Stoffen konnte aber naturgemäß nur sehr gering sein und die Unterbrechung der Leitung des Eisens durch Hinterfüllung verhindert nicht in genügender Weise die Abkühlung des vorgepreßten Glaskörpers. The present invention is this process for the known mechanical To make blowing process usable, in which glass mass is prepressed in a preform and is blown out in a finished mold. Basically iron ones are used for this purpose Pre-compression molds, which, however, also have the disadvantage that they rapidly remove the glass mass and extract a lot of heat. Attempts have already been made to individual parts of this Prepare pre-press molds from poorly thermally conductive materials or through the line To reduce backfilling of the mold walls with such substances. The durability of such molded parts with immediate However, contact of the hot glass mass with the poorly thermally conductive substances could naturally only be very small and the interruption of the conduction of the iron through Backfilling does not sufficiently prevent the pre-pressed glass body from cooling down.
Nach vorliegender Erfindung werden nun die Vorpreßformen ganz oder teilweise aus solchen Stoffen hergestellt, welche leicht Wasser aufsaugen, __ also z. B. aus Holz, Holzstoff, Papierstoff, Asbestfasern, Zement, Sandstein usw. Der Kopfteil der Formen wird zweckmäßig aus Eisen hergestellt, da der sich darin bildende Teil des Glaskörpers im folgenden Blasvorgang nicht verändert werden soll. Der ganze übrige Teil der Formen wird aber, mindestens soweit er mit der Glasmasse in Berührung kommt, aus Stoffen obiger Art hergestellt. Die Form kann ganz und gar aus diesen Stoffen angefertigt oder es können eiserne Formen mit einem Futter aus solchen Stoffen versehen werden. Sollen nun Glaskörper zum Verblasen vorgeformt werden, so durchnäßt man die Formen mit Wasser. Beim Einpressen der -heißen Glasmasse bildet sich dann eine Dampfschicht zwischen Formenwand und Glaskörper. Diese Dampfschicht ermöglicht die Erzielung vorgepreßter Glaskörper mit Feuerpolitur und von einer vollkommenen Bildsamkeit. Dadurch werden in dem folgenden Blasvorgang Glaskörper erhalten von unbedingt gleichmäßiger Glasverteilung und an Aussehen ebenbürtig den durch Mund-According to the present invention, the pre-compression molds are completely or partially made made of such substances, which easily absorb water, __ so z. B. made of wood, Wood pulp, paper pulp, asbestos fiber, cement, sandstone, etc. The head part of the molds is expediently made of iron, since the part of the glass body that forms in it should not be changed in the subsequent blowing process. The whole remaining part of the forms is, however, at least as far as it is with the glass mass comes into contact, made of substances of the above type. The shape can be made entirely from these materials or iron forms can be lined with such materials. Shall now have glass bodies for blowing are preformed, the molds are soaked with water. When pressing in The hot glass mass then forms a layer of vapor between the mold wall and Vitreous. This vapor layer enables pre-pressed glass bodies to be achieved Fire polish and of a perfect malleability. This will result in the following Blowing process Glass bodies have an absolutely even glass distribution and an appearance that is equal to that produced by the mouth.
bläserei erhaltenen Glaskörpern. Da bei der vorgeschlagenen Art des \'"orpressens der Glasmasse Wärme in fühlbarer Menge nicht entzogen wird, so kann man die zum Fertigblasen bestimmten gepreßten Glaskörper auch wesentlich dünner und kleiner, als es seither möglich war, gestalten. Hierdurch kann das Ausblasen der Glaskörper beschleunigt und auf kleine Gegenstände, wie z. B. Flakons,vitreous bodies preserved in the blowing process. Since with the proposed type of \ '"orpressing the Glass mass heat is not withdrawn in a noticeable amount, so you can blow it up certain pressed glass bodies are also much thinner and smaller than it has been since then was possible. This can accelerate the blowing out of the glass body and on small objects such as B. flacons,
ίο ausgedehnt werden, was mit den bekannten Verfahren so gut wie ausgeschlossen ist. Ebenso wie die Vorpreßform kann der Preßstempel aus einem Wasser aufsaugenden Stoffe bestehen. Es kann dann auch die Innenfläche der vorgepreßten Glaskörper mit Feuerpolitur und unbeschränkter Bildsamkeit erhalten werden.ίο be extended what with the known Procedure is as good as impossible. Just like the pre-press mold, the press ram consist of a water-absorbent substance. The inner surface of the pre-pressed glass body can then also be used Fire polish and unlimited malleability are preserved.
Nach erfolgter Pressung muß der Glaskörper gleichzeitig mit dem Preßstempel aus der Vorpreßform entfernt werden, damit er von dem sich in der Form entwickelnden Dampf nicht in die Höhe geblasen werden kann. Der Glaskörper wird daher entweder gleich durch den Preßstempel mit ausgehoben, oder die Form muß nach unten verschwinden, während der Preßstempel nach oben geht. In beiden Fällen hängt der Glaskörper lediglich in dem Kopfteil der Form, der entsprechende seitliche Auflagen besitzen muß. Doch gehören diese bei der auf das Pressen folgenden Weiterbehandlung des Zwischenkörpers zu beobachtenden Vorsichtsmaßregeln nicht zu der geschützten Erfindung.After pressing, the glass body must be removed at the same time as the ram the preform to be removed from the developing in the mold Steam cannot be blown up. The vitreous is therefore either lifted immediately by the ram, or the shape must disappear downwards, while the ram goes up. In both cases the glass body only hangs in the head part of the form, who must have appropriate lateral supports. But these belong to the Press following further treatment of the intermediate body to be observed precautionary measures not related to the protected invention.
