With this adhesive, on the one hand, due to the method previously known in the first operation, a greater strength is to be achieved a sufficient seal of the adhesive seam can be achieved. Furthermore, it is achieved from the device without, however, bringing about an absolutely rigid connection known from the German utility model 7 026 541, while the point-wise plastic plates to be connected to one another over a large area by means of welding are sufficient for welding; namely using a poly- that the double window even with strong mechanical merisats. Furthermore, from the German patent application 1479 292, a method for sealing a seal is also possible. Furthermore, the method according to the invention has the advantage that its implementation is particularly known as a body made of thermoplastic material, which is economically possible isL

Da der Schmelzkleber zunächst nur eine vorläufige mechanische Festigkeit gewährleisten soll, ergibt sich weiterhin der Vorteil, daß bei dem erfindungsgemäßen Verfahren ohne besondere Spannvorrichtungen gearbeitet werden kann. Da die im Hinblick auf die Dauerfestigkeit angebrachten Schweißpunkte in verhältnismäßig großen Abständen gesetzt werden, gestartet die Plastizität des Schmelzklebers eine geringfügige Bewegung der Platten gegeneinander, wie sie durch Spannungsausgleich bei Erwärmung ausgelöst werden kann. Since the hotmelt adhesive is initially only intended to ensure temporary mechanical strength, there is also the advantage that the method according to the invention can be used without special clamping devices. Since the weld points made with a view to fatigue strength are set at relatively large intervals, the plasticity of the hot melt adhesive starts a slight movement of the plates against each other, as can be triggered by equalizing tension when heated.

Im folgenden wird die Erfindung an der Herstellung einer solchen Doppelscheibe, z. B. für ein Wohnwagenfenster, beschrieben, die in der Zeichnung dargestellt ist In dieser zeigtIn the following the invention is applied to the production of such a double disc, e.g. B. for a caravan window, which is shown in the drawing In this shows

Fig. 1 einen Längsschnitt durch die Doppel scheibe, und zwar im oberen Teil nach dem Einlegen der Schmelzkleberschnur und im unleren Teil nach dem Verflüssigen der Schnur und dem Zusammenpressen der Scheiben, Fig. 1 is a longitudinal section through the double disk, namely in the upper part after inserting the hot melt adhesive cord and in the lower part after the cord has liquefied and the disks have been compressed,

Fig. 2 eine Ansicht der fertigen Doppelscheibe mit der Lage des Heizleiters und der Schweißpurskte. 2 shows a view of the finished double pane with the position of the heating conductor and the welding tracks.

In Fig. 1 sind eine Planscheibe 1 und eine wan nenförmig verformte Scheibe 2 aus einem Poiymeta- crylat zusammengesetzt. In Fig. 1, oberer Teil, liegt zwischen ihnen eine Schmelzkleberschnur 3, die vorher auf eine der beiden Scheiben unter leichter Er- wärmung mittels eines längs des Scheibenrandes ge führten pistolenartigen Heißhifigerätes aufgebracht wurde; es handelt sich hierbei um einen Haftvorgang, um die Lage der Schmelzkleberschnur 711m Scheibenrande 7.U fixieren. In diese: Schnur 3 ist ein elek- frischer Leiter 4, vorzugsweise ein Widerstandsdrain aus Constantan, eingebettet. Die Enden der Schnur werden herausgeführt, und die Enden des Leiters werden an einen (nicht dargestellten) Regeltransformator angeschlossen (0, ft in Fig. 2). In Fig. 1, a face plate 1 and a wan NEN-shaped deformed plate 2 are composed of a poly- methacrylate . In FIG. 1, upper part, there is a hot melt adhesive cord 3 between them, which was previously applied to one of the two panes with slight heating by means of a pistol-like hot tool guided along the edge of the pane; This is fixed to an adhesion process, 711m to the position of the hot melt adhesive cord disc edge 7.U. In this: cord 3, an electrical conductor 4, preferably a resistance drain made of Constantan, is embedded. The ends of the cord are brought out, and the ends of the conductor are connected to a regulating transformer (not shown) (0, ft in Fig. 2).

Fig. J, unterer Teil, zeigt die nach Verflüssigung der Schmelzkleberschnur 3 und Zusammenpressen der Scheiben 1, 2 ausgepreßte Klebenaht 5. FIG. J, lower part, shows the adhesive seam 5 pressed out after the melt adhesive cord 3 has liquefied and the panes 1, 2 have been pressed together.

Sobald der Schmelzkleber seine Endfestigkeit erreicht hat, wird die Doppelscheibe aus der Preß vorrichtung genommen, und in einer Ultraschall-Schweißmaschine werden zusätzlich am Rande der Scheibe, möglichst an der Kante, außerhalb der nach dem Einbau sichtbaren Bereiches, Warzenschweißungen 6 vorgenommen. Diese Scihweißpunkte oder -warzen haben einen Abstand von 20 bis 40, vorzugsweise 30 cm und liegen an den Ecken enger (F i g. 2). Diese Punktschweißung sichert eine echte, unlösbare Verbindung der beiden Scheiben 1, 2 miteinander.As soon as the hotmelt adhesive has reached its final strength, the double pane is removed from the press device taken, and in an ultrasonic welding machine are additionally on the edge of the Washer, if possible on the edge, outside of the area visible after installation, wart welds 6 made. These welding points or -Warts are 20 to 40 cm apart, preferably 30 cm, and are closer at the corners (Fig. 2). This spot welding ensures a real, permanent connection between the two panes 1, 2.

Die Beschreibung zeigt, daß die Herstellung nur eine einfache Spann- und Preßvorrichtung benötigt und keinerlei Fertigkeiten vorai^ietzt. Die Ausfüh rung kann im einzelnen je nach Arnvendungszweck abgewandelt werden, insbesondere müssen die Klebe nähte nicht längs des Plattenrandes verlaufen und die Schweißpunkte nicht im Bereich der Klebenähte lie gen. Es füllt auch in den Rahmen der Erfindung, wenn di-r Schmelzkleber in flüssigem Zustande als Raupe anigeDiachi und dabei — durch entsprechende Gestaltung der Zuführvorrichtung — der Heizleiter in die Raupe eingebettet wird, die rasch erstarrt. Nach dem Zusammenbau der Platten wird die Raupe dann mittels eines durch den Leiter geschickten Stromes erwärmt, wie dies vorher an der Schmelzkleberschnur geschildert wurde, und das Verfahren zu Ende geführt, wie beschrieben.The description shows that the production only requires a simple clamping and pressing device and does not require any skills. The execution can be modified in detail depending on the purpose of use, in particular the adhesive seams do not have to run along the edge of the panel and the welding points do not lie in the area of the adhesive seams. It is also within the scope of the invention if the hot-melt adhesive is in a liquid state as a caterpillar anigeDiachi and - through the appropriate design of the feed device - the heating conductor is embedded in the caterpillar , which quickly solidifies. After the panels have been assembled, the bead is then heated by means of a current sent through the conductor, as previously described on the melt adhesive cord, and the process is completed as described.
