Description
Verfahren zum Herstellen von mit einem von Luft verschiedenen Gas gefülltem Isolierglas Process for producing insulating glass filled with gas other than air
Die Erfindung betrifft ein Verfahren zum Füllen von Isolierglas mit einem von Luft verschiedenen Gas (Schwergas, z.B. Schwefelhexafluorid, einem Edelgas, oder Mischungen von Luft mit verschiedenen Gasen). The invention relates to a method for filling insulating glass with a gas other than air (heavy gas, for example sulfur hexafluoride, a noble gas, or mixtures of air with various gases).
Im Stand der Technik sind verschiedene Verfahren für das Füllen von Isolierglas mit Schwergas bekannt. Als Beispiele werden genannt die Verfahren und Vorrichtungen, die in der AT 368985 B (= DE 31 39 856 A und US 4,369,84 A), der EP 0 324 333 A, der AT 399 500 B, der AT 408 982 B und der AT 409 128 B gezeigt und beschrieben sind. Various methods for filling insulating glass with heavy gas are known in the prior art. Examples which may be mentioned are the processes and devices described in AT 368985 B (= DE 31 39 856 A and US Pat. No. 4,369,84 A), EP 0 324 333 A, AT 399 500 B, AT 408 982 B and US Pat AT 409 128 B are shown and described.
Problematisch bei den bekannten Verfahren zum Füllen von Isolierglas mit einem von Luft verschiedenen Gas ist es, dass wenigstens in dem Bereich, durch den das Gas in den Innenraum des Isolierglases einzufüllen ist, wo also der Gastausch stattfinden soll, zwischen dem Abstandhalter und wenigstens einer der Glasscheiben ein Abstand vorliegen muss. Dies wird in der Praxis oft so erreicht, dass eine Glasscheibe in der Gasfüllvorrichtung mit Abstand von der ihr zugekehrten Fläche des Abstandhalters gehalten wird, indem sie an eine mit Unterdruck beaufschlagte Platte der Gasfüllvorrichtung angesaugt und von dieser gehalten wird. A problem in the known method for filling insulating glass with a gas other than air is that at least in the area through which the gas is to be filled into the interior of the insulating glass, ie where the exchange is to take place between the spacer and at least one of Glass panes must be a distance. In practice, this is often achieved by holding a glass sheet in the gas filling device at a distance from the surface of the spacer facing it, by sucking it onto and holding it by a plate of the gas filling device subjected to negative pressure.
Der Erfindung liegt die Aufgabe zu Grunde ein Verfahren anzugeben, mit dem der Abstand zwischen wenigstens einer der Glasscheiben und dem Abstandhalter erreicht werden kann, ohne dass eine Glasscheibe an eine Platte einer Gasfüllvorrichtung angesaugt und so im Abstand vom Abstandhalter gehalten werden muss. The invention has for its object to provide a method by which the distance between at least one of the glass panes and the spacer can be achieved without a glass pane to be sucked to a plate of a gas filling and kept at a distance from the spacer.
Gelöst wird diese Aufgabe erfindungsgemäß mit einem Verfahren, das die Merkmale von Anspruch 1 aufweist. This object is achieved according to the invention with a method having the features of claim 1.
Bevorzugte und vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. Preferred and advantageous embodiments of the invention are the subject of the dependent claims.
Da beim erfindungsgemäßen Verfahren im Bereich des Abstandhalters nur während des Gasfüllvorganges wirksame Distanzmittel vorgesehen sind, die während des Füllvorganges den Abstand zwischen dem Abstandhalter und der ihm gekehrten Fläche der Glasscheibe sicherstellen, ist es nicht mehr erforderlich die Glasscheibe im Abstand vom Abstandhalter zu halten, indem sie von einer Saugplatte gehalten wird. Since in the method according to the invention in the region of the spacer effective distance means are provided only during the gas filling process, which ensure the distance between the spacer and the swept surface of the glass pane during the filling process, it is no longer necessary to keep the glass pane at a distance from the spacer by it is held by a suction plate.
Die Distanzmittel können über die gesamte Länge des Abstandhalters verteilt angeordnet sein, oder aber nur in einem Bereich des Abstandhalters, nämlich in dem Bereich, in dem eine Öffnung vorliegen soll, über die der Innenraum des Isolierglases mit Gas zu füllen ist. Die Distanzmittel können Erhebungen (Vorsprünge) in dem Strang aus Kleber, der zum klebenden Verbinden der Glasscheibe mit dem Abstandhalter dient, sein. Diese Erhebungen können bereichsweise Verdickungen des Stranges aus Kleber oder aber auf den Strang aus Kleber aufgesetzte und in diesen eindrückbare Distanzmittel sein. Falls die Abstandhalter aus thermoplastischem oder elastoplastischem Werkstoff bestehen, können die Distanzmittel in den Abstandhalter eindrückbar sein. The spacer means may be arranged distributed over the entire length of the spacer, or only in a region of the spacer, namely in the region in which an opening is to be present, via which the interior of the insulating glass is to be filled with gas. The spacer means may be protrusions in the strand of adhesive used to adhesively bond the glass sheet to the spacer. These surveys may be regions of thickening of the strand of adhesive or patch on the strand of adhesive and in this depressible spacer. If the spacers are made of thermoplastic or elastoplastic material, the spacer means can be pressed into the spacer.
Alternativ kann vorgesehen sein, dass die Distanzmittel an den Rand der Glasscheibe angesetzte und dort klemmend festgesetzte Distanzmittel sind. Diese Distanzmittel werden nach dem Füllvorgang, noch vor dem Verpressen des Isolierglases wieder abgenommen. Alternatively, it can be provided that the spacer means are attached to the edge of the glass pane and fixed there by clamping distance means. These spacers are removed after the filling process, before the compression of the insulating glass again.
Wenn an den Rand der Glasscheibe angesetzte Distanzmittel (Klipse) außerhalb des Stranges aus Kleber (Butylkautschuk) angeordnet sind, also nur den nicht mit Kleber belegten Bereich des Abstandhalters berühren, können sie auch bis nach dem Verpressen des Isolierglases angesetzt verbleiben und es genügt, wenn die Distanzmittel vor dem Versiegeln des Isolierglases (Füllen der Randfuge mit Versiegelungsmasse) abgenommen werden. If attached to the edge of the glass spacer (clips) outside the strand of adhesive (butyl rubber) are arranged, so only touch the not occupied with adhesive portion of the spacer, they may remain attached until after pressing the insulating glass and it is sufficient if the spacers are removed before sealing the insulating glass (filling the edge joint with sealant).
Das erfindungsgemäße Verfahren ist nicht nur für Zwei-Scheiben-Isolierglas geeignet, sondern auch für Drei- und Mehr-Scheiben-Isolierglas, wobei der Strang aus Kleber entweder auf den der den äußeren Glasscheiben zugekehrten Flächen des Abstandhalters und/oder der Innenseite der Glasscheiben angebracht wird. Auch hier können Distanzmittel Erhöhungen im Strang aus Kleber, an diesen angesetzte Distanzklötze (Stöpsel) oder aber Klipse, wie oben beschrieben, oder aber in den Abstandhalter (aus Kunststoff) eindrückbare Distanzmittel sein. The inventive method is suitable not only for two-pane insulating glass, but also for triple and multi-pane insulating glass, wherein the strand of adhesive mounted either on the facing the outer glass panes surfaces of the spacer and / or the inside of the glass sheets becomes. Here too, spacer means can be elevations in the strand of adhesive, spacers (plugs) attached thereto, or clips, as described above, or else spacers which can be pressed into the spacer (made of plastic).
Wenn die Distanzmittel im Bereich des Stranges aus Kleber vorgesehen sind, also Erhöhungen desselben oder auf diesen aufgesetzte Stöpsel sind, ist vorteilhaft, wenn die Distanzmittel eine solche Abmessung haben, dass sie beim Verpressen des Isolierglases nach dem Gasfüllvorgang in dem Strang aus Kleber hineingedrückt werden, sodass dieser seine Funktion als Diffusionssperre erfüllen kann. If the spacers are provided in the region of the strand of adhesive, that is elevations thereof or on this patch plug, it is advantageous if the spacer means have such a dimension that they are pressed in the strand of adhesive during the compression of the insulating glass after the gas filling process, so that it can fulfill its function as a diffusion barrier.
Ein Vorteil des erfindungsgemäßen Verfahrens ist es auch, dass an sich bekannte Gasfüllvorrichtungen (Gasfüllpressen) verwendet werden können, beispielsweise die in den oben genannten Dokumenten offenbarten Gasfüllvorrichtungen, wobei lediglich das Abheben der einen Glasscheibe, um zwischen ihr und dem Abstandhalter eine Öffnung für den Eintritt von Gas in den Innenraum des Isolierglases zu erzielen, entfallen kann. It is also an advantage of the method according to the invention that gas filling devices known per se (gas filling presses) can be used, for example the gas filling devices disclosed in the abovementioned documents, wherein only the lifting of the one glass pane to form an opening for entry between it and the spacer To achieve gas in the interior of the insulating glass, can be omitted.
Weitere Einzelheiten und Merkmale der Erfindung ergeben sich aus der nachstehenden Beschreibung von Ausführungsbeispielen anhand der Zeichnungen. Es zeigen Fig. 1 bis 4 in schematisierten Schrägansichten verschiedene Ausführungsformen von Dreifach-Isolierglas, wobei das erfindungsgemäße Verfahren zum Füllen des Innenraumes von Isolierglas mit Gas schematisiert dargestellt ist, und Fig. 5 bis 7 Ausführungsformen mit Distanzmitteln an einem Abstandhalter aus Kunststoff. Further details and features of the invention will become apparent from the following description of exemplary embodiments with reference to the drawings. 1 to 4 show diagrammatic oblique views of various embodiments of triple insulating glass, wherein the inventive method for filling the interior of insulating glass with gas is shown schematically, and Fig. 5 to 7 embodiments with spacers on a spacer made of plastic.
Bei der in Fig. 1 gezeigten Ausführungsform des Füllens von Drei-Scheiben-Isolierglas 1 , das in Fig. 1 als "Rohling" bestehend aus einem Paket aus drei Glasscheiben 3, 4 und Abstandhaltern 5 vorliegt, mit einem von Luft verschiedenem Gas (Schwergas) wird das Gas aus einem Doppelkanal 9 in beide Innenräume 7 zwischen den äußeren Glasscheiben 3 und der mittleren Glasscheibe 4 geleitet. Bei der in Fig. 1 gezeigten Ausführungsform sind an der mittleren Glasscheibe 4 zwei Abstandhalter 5 angebracht, die auf ihren, den äußeren Glasscheiben 3 zugekehrten Flächen einen Strang 11 aus diffusionsdichtem Kleber, z.B. Butylkleber, mit Vorsprüngen 13 (Abstand der Vorsprünge 13 voneinander etwa 50 bis 500 mm) tragen. So wird gewährleistet, dass zwischen den äußeren Glasscheiben 3 und den Abstandhaltern 5, die an der inneren Glasscheibe 4 (mittlere Glasscheibe) angeordnet sind, Freiräume 15 verbleiben, durch die das Gas aus dem Doppelkanal 9 in die Innenräume 7 strömen kann, wie dies in Fig. 1 durch Pfeile 21 symbolisiert ist. In the embodiment shown in Fig. 1 of the filling of three-pane insulating glass 1, which is present in Fig. 1 as a "blank" consisting of a package of three glass sheets 3, 4 and spacers 5, with a gas other than air (heavy gas ), the gas from a double channel 9 in both interior spaces 7 between the outer glass sheets 3 and the middle glass pane 4 is passed. In the embodiment shown in Fig. 1, two spacers 5 are attached to the central glass pane 4 and, on their faces facing the outer glass panes 3, comprise a strand 11 of diffusion-proof adhesive, e.g. Butyl adhesive, with projections 13 (distance of the projections 13 from each other about 50 to 500 mm) wear. This ensures that free spaces 15 remain between the outer glass panes 3 and the spacers 5, which are arranged on the inner glass pane 4 (middle pane of glass), through which the gas can flow from the double channel 9 into the interior spaces 7, as shown in FIG Fig. 1 is symbolized by arrows 21.
Sobald der Füllvorgang beendet ist, also der gewünschte Füllgrad der Innenräume 7 mit Schwergas erreicht worden ist, wird die Gaszufuhr unterbrochen. Die äußeren Glasscheiben 3 werden in einer Presse, die gleichzeitig die Vorrichtung zum Füllen mit Schwergas sein kann (Gasfüllpresse), aufeinander zu verschoben, sodass sie an den Strängen 11 an beiden Abstandhaltern 5 anliegen, dabei die Vorsprünge 13 verformen und schlussendlich flächig an den Strängen 11 anliegen. As soon as the filling process has ended, ie the desired filling level of the interior spaces 7 with heavy gas has been reached, the gas supply is interrupted. The outer glass sheets 3 are in a press, which may be the same device for filling with heavy gas (Gasfüllpresse), moved towards each other, so that they rest against the strands 11 on both spacers 5, thereby deforming the projections 13 and finally flat on the strands 11 abut.
Das so verpresste Isolierglas (Rohling) wird dann einer Vorrichtung zum Füllen der Randfuge mit Versiegelungsmasse (Versiegelungsautomat) zugeführt, in welcher in die beiden Randfugen, die nach innen von den Abstandhaltern 5 und seitlich von den Glasscheiben 3 undThe thus pressed insulating glass (blank) is then fed to a device for filling the edge joint with sealant (sealing machine), in which in the two edge joints, the inwardly from the spacers 5 and the side of the glass sheets 3 and
4 begrenzt sind, Versiegelungsmasse (meist eine Masse auf Polysulfidbasis) eingespritzt wird. 4 are limited, sealant (usually a polysulphide-based mass) is injected.
Die in Fig. 2 gezeigte Ausführungsform unterscheidet sich von der in Fig. 1 gezeigten dadurch, dass die Stränge 11 aus Kleber (Butylkautschuk) nicht auf den Abstandhaltern 5 sondern an den Innenseiten der äußeren Glasscheiben 4 aufgebracht sind. Auch hier sind auf den zu den Abstandhaltern 5 hin weisenden Flächen der Stränge 1 1 aus Kleber Vorsprünge 13 vorgesehen, die während des Gasfüllvorganges einen Abstand zwischen den AbstandhalternThe embodiment shown in FIG. 2 differs from that shown in FIG. 1 in that the strands 11 of adhesive (butyl rubber) are not applied to the spacers 5 but to the insides of the outer glass panes 4. Again, on the spacers to the 5 facing out surfaces of the strands 1 1 of adhesive projections 13 are provided, which during the Gasfüllvorganges a distance between the spacers
5 und den äußeren Glasscheiben 4 sicherstellen, sodass Gas in die Innenräume 7 zwischen den Glasscheiben 3 und 4 einströmen kann. 5 and the outer glass panes 4 ensure that gas can flow into the interiors 7 between the glass sheets 3 and 4.
In Fig. 3 ist eine Ausführungsform gezeigt, die grundsätzlich der Anordnung von Fig. 1 ähnlich ist, wobei hier die Abstandhalter 5 zu einem Abstandhalter 5 vereinigt sind und die mittlere Glasscheibe 4 nur bis in den Abstandhalter 5 ragt. Um die mittlere Glasscheibe 4 und den Abstandhalter 5 während des Füllvorganges zu stützen, ist auf dem Doppelkanal 9, aus dem Gas zugeführt wird, eine Stützleiste 19 vorgesehen. An Stelle der Stützleiste 19 können am Doppelkanal 9 auch einzelne Stützvorsprünge angebracht sein. In Fig. 3, an embodiment is shown, which is basically similar to the arrangement of Fig. 1, in which case the spacers 5 are combined to form a spacer 5 and the middle Glass pane 4 only extends into the spacer 5. To support the middle glass pane 4 and the spacer 5 during the filling process, a support strip 19 is provided on the double channel 9, is supplied from the gas. Instead of the support bar 19 may be attached to the double channel 9 and individual support projections.
Die in Fig. 4 gezeigte Ausführungsform unterscheidet sich von der in Fig. 3 gezeigten dadurch, dass die Stränge 11 aus Kleber nicht auf den Außenflächen, also den den äußeren Glasscheiben 3 zugekehrten Flächen des Abstandhalters 5, sondern auf den nach innen weisenden Flächen der äußeren Glasscheiben 3 angebracht sind. The embodiment shown in Fig. 4 differs from that shown in Fig. 3 in that the strands of adhesive 11 not on the outer surfaces, ie the outer glass plates 3 facing surfaces of the spacer 5, but on the inwardly facing surfaces of the outer Glass panels 3 are mounted.
Anstelle der durch Erhebungen der Stränge 11 aus Kleber gebildeten Vorsprünge 13 können als Distanzmittel beim erfindungsgemäßen Verfahren auch auf die Stränge 11 aus Kleber aufgesetzte Distanzmittel in Form von Knöpfen, Stöpseln oder ähnlichen verwendet werden, die beim Verpressen des Isolierglases (wie oben beschrieben) nachdem der Füllvorgang beendet ist, in die Stränge 11 hineingedrückt werden. Instead of formed by elevations of the strands 11 of adhesive projections 13 can be used as spacers in the process according to the invention also on the strands 11 of adhesive patch spacers in the form of buttons, plugs or the like, during compression of the insulating glass (as described above) after the Filling is completed, are pressed into the strands 11.
Es ist auch eine Ausführungsform in Betracht gezogen, bei welcher Stränge 11 aus Kleber sowohl auf den äußeren Glasscheiben 3, als auch auf den nach außen weisenden Flächen des/der Abstandhalter 5 vorgesehen sind. Also contemplated is an embodiment in which strands of adhesive 11 are provided on both the outer glass sheets 3 and the outwardly facing surfaces of the spacer 5.
An Stelle der in den Fig. 1 bis 4 gezeigten Ausführungsform, bei welcher die Distanzmittel, die vorübergehend, also nur während des Füllvorganges wirksam sind, um wenigstens in einem Bereich eine spaltförmige Öffnung zwischen dem Abstandhalter 5 und einer der äußeren Glasscheiben 3 zu bilden, Vorsprünge 13 in Form von Erhebungen des Stranges 11 aus Kleber oder von auf dem Strang 11 aus Kleber aufgesetzte Distanzmittel sind, können im Rahmen der Erfindung auch Distanzmittel verwendet werden, die auf den Rand wenigstens einer der Glasscheiben 3 (bei einem Zwei-Scheiben-Isolierglas an wenigstens einer der Glasscheiben) aufgesetzt werden, um Abstand zwischen der Außenfläche des Abstandhalters 5 und den Glasscheiben 3 zu gewährleisten, um so spaltförmige Öffnungen für den Gastausch zu bilden. Diese Distanzmittel können federnde Distanzmittel sein, die am Abstandhalter 5 lediglich in einem Bereich angreifen, der außerhalb des mit dem Strang 11 aus Kleber beschichteten Bereiches des Abstandhalters 5 liegt. In place of the embodiment shown in FIGS. 1 to 4, in which the spacer means, which are temporarily effective, ie only during the filling process, to form at least in one area a gap-shaped opening between the spacer 5 and one of the outer glass panes 3, Projections 13 in the form of elevations of the strand 11 of adhesive or on the strand 11 of adhesive patch spacers are, in the invention can also be used spacers on the edge of at least one of the glass panes 3 (in a two-pane insulating glass on at least one of the glass panes) to ensure spacing between the outer surface of the spacer 5 and the glass sheets 3, so as to form gap-shaped openings for the gas exchange. These spacers can be resilient spacers which engage the spacer 5 only in a region which lies outside the area of the spacer 5 coated with the strand 11 of adhesive.
Diese Distanzmittel werden spätestens vor dem Versiegeln des Rohlings abgenommen. These spacers are removed at the latest before the blank is sealed.
Wenn die Distanzmittel im Bereich des Stranges 11 aus Kleber auf dem Abstandhalter 5 anliegen, werden sie abgenommen bevor das Paket aus wenigstens zwei Glasscheiben 3, 4 und Abstandhalter 5 zu einem Rohling von Isolierglas verpresst wird. If the spacer means in the region of the strand 11 of adhesive on the spacer 5, they are removed before the package is pressed from at least two glass sheets 3, 4 and 5 spacer to a blank of insulating glass.
Bei der in Fig. 5 gezeigten Ausführungsform ist der Abstandhalter 5 zwischen den Glasscheiben 3 ein Abstandhalter 5 aus Kunststoff. Solche Abstandhalter 5 aus Kunststoff sind beispielsweise aus der DE-A 30 02 904 bekannt und werden häufig als "swiggle-strip" bezeichnet. Dieser Abstandhalter 5 hat die Form eines Bandes mit Rechteckquerschnitt, das mit Schutzfolien versehen von einer Vorratstrommel abgezogen wird und mittels einer Appliziervorrichtung auf die Glasscheibe 3 aufgebracht wird. Bandförmige Abstandhalter 5 auf Basis von Butylkautschuk sind zäh wie Plastik und stark klebend, damit eine gasdichte Verbindung zwischen den Glasscheiben 3 des Isolierglases möglich ist. In the embodiment shown in Fig. 5, the spacer 5 between the Glass sheets 3, a spacer 5 made of plastic. Such spacers 5 made of plastic are known for example from DE-A 30 02 904 and are often referred to as "swiggle-strip". This spacer 5 has the shape of a strip with a rectangular cross-section, which is provided with protective films withdrawn from a storage drum and is applied by means of an applicator on the glass pane 3. Band-shaped spacers 5 based on butyl rubber are tough as plastic and strongly adhesive, so that a gas-tight connection between the glass sheets 3 of the insulating glass is possible.
Bekannt sind auch Abstandhalter 5 aus elastoplastischem Kunststoff auf Basis von Polyurethan oder ähnlichem. Diese Abstandhalter 5 haben ebenfalls Rechteckquerschnitt und tragen auf ihrer späteren Außenseite eine Diffusionssperre, z.B. eine Lage aus Aluminiumfolie. Diese elastoplastischen Abstandhalter 5 sind an ihren zur Anlage an den Glasscheiben 3 bestimmten Schmalseiten herstellerseitig mit einer dünnen bis zum Applizieren des Abstandhalters mit Schutzfolien abgedeckten Beschichtung aus einem stark adhäsiven Kleber versehen. Also known are spacers 5 made of elastoplastic plastic based on polyurethane or the like. These spacers 5 are also of rectangular cross-section and carry on their later outer side a diffusion barrier, e.g. a layer of aluminum foil. These elastoplastic spacers 5 are provided at their intended for contact with the glass sheets 3 narrow sides manufacturer with a thin to cover the application of the spacer with protective films covered coating of a highly adhesive adhesive.
Bei der in Fig. 5 gezeigten Ausführungsform ist in den Abstandhalter 5 aus Kunststoff als Distanzmittel eine Reihe von Stiften 31 eingesetzt, und zwar zunächst so, dass die freien Enden der Stifte 31 in Richtung auf die Glasscheibe 3, auf welcher der Abstandhalter 5 zunächst noch nicht anliegt, vorstehen und die Glasscheibe 3 im Abstand vom Abstandhalter 5 halten. Nach dem Füllvorgang des Innenraumes 7 mit Gas werden die Stifte 31 beim Zusammenbau und Verpressen des Isolierglases in den Abstandhalter 5 aus Kunststoff eingepresst und von diesem umschlossen. In the embodiment shown in Fig. 5, a number of pins 31 is inserted into the spacer 5 made of plastic as a spacer means, and initially so that the free ends of the pins 31 in the direction of the glass sheet 3, on which the spacer 5 initially does not lie, protrude and hold the glass 3 at a distance from the spacer 5. After filling the inner space 7 with gas, the pins 31 are pressed during assembly and compression of the insulating glass in the spacer 5 made of plastic and enclosed by this.
Bei der in Fig. 6 gezeigten Ausführungsform sind als Distanzmittel mehrere auf den Abstandhalter 5 aufgesetzte, im Wesentlichen U-förmige Bügel (Klipse) 33 vorgesehen, die reibschlüssig auf der Außen- und Innenseite des Abstandhalters 5 klemmend anliegen und so den Abstand zum Bilden des den Füllspalt bildenden Freiraumes 15 definieren. Auch die Bügel 33 werden beim Verpressen des Isolierglases in den Abstandhalter 5 hineingedrückt und von diesem umschlossen. In the embodiment shown in FIG. 6, a plurality of spacers 5 placed on the spacer 5, substantially U-shaped brackets (clips) 33 are provided as a spacer means, which bear frictionally on the outside and inside of the spacer 5 in a clamping manner and thus distance to form the define the filling gap forming free space 15. Also, the bracket 33 are pressed in the pressing of the insulating glass in the spacer 5 and enclosed by this.
Bei der in Fig. 7 gezeigten Ausführungsform sind als Distanzmittel U-Haken 35 vorgesehen, die in den Abstandhalter 5 zunächst nur so weit eingesteckt sind, dass ihr Steg an der Glasscheibe 3 anliegt, die dem Abstandhalter 5, der an der anderen Glasscheibe 3 angebracht ist, gegenüberliegt, um so den Freiraum 15 für den Gasdurchtritt zu bilden. Auch die Distanzmittel in Form von U-Haken 35 werden beim Verpressen des Isolierglases in den Abstandhalter 5 eingedrückt und von dessen Werkstoff umschlossen, sodass, so wie bei den Ausführungsformen von Fig. 5 und 6, eine diffusionsdichte Verbindung der Glasscheiben 3 mit dem Abstandhalter 5 erreicht wird. Zusammenfassend kann ein Ausführungsbeispiel der Erfindung wie folgt beschrieben werden: In the embodiment shown in FIG. 7, U-hooks 35 are provided as spacers, which are initially inserted into the spacer 5 only so far that their web abuts against the glass pane 3, which is the spacer 5 attached to the other glass pane 3 is opposite, so as to form the space 15 for the passage of gas. The spacers in the form of U-hook 35 are pressed into the spacer 5 during pressing of the insulating glass and enclosed by its material, so that, as in the embodiments of FIGS. 5 and 6, a diffusion-tight connection of the glass sheets 3 with the spacer. 5 is reached. In summary, an embodiment of the invention can be described as follows:
Zum Füllen von Isolierglas mit einem von Luft verschiedenen Gas wird zwischen dem Abstandhalter 5 und der Glasscheibe 3 ein Freiraum 15 für den Eintritt von Gas in den Innenraum 7 des Isolierglases dadurch gewährleistet, dass im Bereich des Stranges 11 aus Kleber, der auf der Innenseite der Glasscheibe 3 oder einer Seitenfläche des Abstandhalters 5 aufgebracht ist, Distanzmittel, beispielsweise in Form von Vorsprüngen 13 des Stranges 11 aus Kleber, vorgesehen sind. Diese Vorsprünge 13 werden beim Verpressen des Scheibenpaketes aus (wenigstens) zwei Glasscheiben 3 mit dazwischen gefügtem Abstandhalter 5 zu einem Isolierglasrohling 1 in den Strang 1 aus Kleber gedrückt, worauf der Isolierglasrohling 1 zum Versiegeln einer Versiegelungsstation zugeführt wird. For filling insulating glass with a gas other than air between the spacer 5 and the glass plate 3, a free space 15 for the entry of gas into the interior 7 of the insulating glass is ensured by the fact that in the region of the strand 11 of adhesive on the inside of the Glass plate 3 or a side surface of the spacer 5 is applied, spacer means, for example in the form of projections 13 of the strand 11 of adhesive, are provided. These projections 13 are pressed during compression of the disk pack of (at least) two glass sheets 3 with spacer 5 joined between them to form an insulating glass blank 1 in the strand 1 of adhesive, after which the insulating glass blank 1 is fed to seal a sealing station.
