Description

Es ist bekannt Luftkissen in der Weise herzustellen, daß zwei luftdichte Folien durch Klebe-oder Schweißnäihlte derart in Räume abgetrennt werden, daß ein Luftpolster entsteht, dessen örtliche Dilclse im aufgeblasenen Zustand zwischen einem Maximum und Null schwankt. It is known to produce air cushions in such a way that two are airtight Foils are separated into spaces by adhesive or weld seams in such a way that a Air cushion arises, the local dilclse of which in the inflated state between a maximum and zero fluctuates.

Um dem Luftpolster eine gleichmäßigere Dicke zu geben, wird gemäß der Erfindung jede Folie eines aus drei oder mehr Foiien bestehenden Pakets jeweils mit der benachbaften Folie an zahlreichen Stellen derart verschweißt oder verklebt, daß die einzelnen Schweißstellen der übereinanderliegenden Folien gegeneinander versetzt sind. Außerdem kann man erfindungsgemäß je zwei benachbarte Folien des Pakets durch ein Netz von örtli!chen Schweißungen zusammenheften, wobei das Netz von Lage zu Lage um eine hallbe Maschenweite verschoben wird. In order to give the air cushion a more even thickness, according to of the invention, each sheet of a package consisting of three or more sheets, respectively welded or glued to the adjacent film in numerous places in such a way that that the individual welds of the overlapping foils against each other are offset. In addition, according to the invention, two adjacent foils can be used Staple the package together by a network of local welds, the network is shifted from layer to layer by a similar mesh size.

Diese Schweißungen oder Klebungen können z. B. kreisförmige Gestalt aufweisen.These welds or bonds can, for. B. circular shape exhibit.

Aus einem so vorbereiteten aufblasbaren Gebilde können luft-, wasser- und wärmeundurchlässige Teile geschnitten oder biegungsfeste Bauteile gebildet werden, indem die Konturen luftdicht verschlossen und im Innern ein Überdruck hergestelilt wird. Die Platte oder die daraus gefertigten Teile haben einen regelmäßigen wabenförmigen Aufbau, wobei die Größe der Waben von dem Abstand der örtlichen Schweißungen abhängt. Um zu erreichen, daß alle Wabenschichten miteinander kommunizieren, können die inneren Folien, z. B. innerhalb der lokalen Schweißungen, perforiert werden. An inflatable structure prepared in this way can produce air, water and heat-impermeable parts are cut or rigid components are formed, by hermetically sealing the contours and creating an overpressure inside will. The plate or the parts made from it have a regular honeycomb shape Construction, whereby the size of the honeycomb depends on the distance between the local welds. In order to ensure that all honeycomb layers communicate with one another, the inner Foils, e.g. B. within the local welds, perforated.

Das Zusammenfügen der Folien in der gewünschten Ordnung und die Herstellung der Klebungen oder Schweißungen geschieht entweder in der Reihenfolge, wie diese schrittweise unzugänglich werden, oder freizügiger nach einer Vorbereitung der Folien in einem Spritz- oder Druckverfahren, bei dem die Stellen, an denen keine Klebungen oder Schweißungen eintreten sollen, gepudert oder metallisiert oder in anderer Weise so verändert werden, daß die Klebe- oder Schweißfäthiigke.it verlorengeht. The assembly of the foils in the desired order and the production the gluing or welding is done either in the order in which this is done gradually become inaccessible, or more revealing after preparing the slides in a spraying or printing process, in which the places where there are no bonds or welds are to occur, powdered or metallized or in some other way changed in such a way that the adhesive or welding capacity is lost.

In der Zeichnung sind einige Ausführungsbeispiele dargestellt. Es zeigt Fig. 1 den wabenförmigen Aufbau einer aufblasbaren Platte aus drei Folien, Fig. 2 eine aufblasbare Platte aus fünf Folien im Schnitt, Fig. 3 das benutzte Schweißmuster mit kreis-oder kreisringförmigen Schweißstellen, Fig. 4 und 5 die gleichzeitige Herstellung mehrerer ,übereinanderliegender Schweißungen in einem Arbeitsverfahren. Some exemplary embodiments are shown in the drawing. It Fig. 1 shows the honeycomb structure of an inflatable plate made of three foils, FIG. 2 shows an inflatable plate made of five foils in section, FIG. 3 shows the welding pattern used with circular or annular welds, FIGS. 4 and 5 the simultaneous Production of several superimposed welds in one work process.

Die Folien 2 bis 7 des aus acht Folien bestehenden Pakets werden an den Stellen und auf der Seite, auf der keine Schweißung eintreten soll, bedruckt oder mit nichtschweißendem Material I5 belegt, so daß bei der Schweißung zwischen den Elektroden 14 die gewünschte paarweise Bindung der Folien eintritt. Werden die Folien zuvor noch an den Stellen I6 perforiert, so kann der Sdhwellkörper nach Herstellung der Randschweißung als Ganzes aufgeblasen werden. - Die Perforationen I6 sind durch die Schweißungen I7 entlastet und können dazu dienen, die Folien in der gewün.schten Ordnung zu stapeln. Slides 2 through 7 of the eight-slide package will be printed in the places and on the side where no welding should occur or covered with non-welding material I5, so that between the electrodes 14 the desired bonding of the foils in pairs occurs. Will the Foils previously perforated at points 16, so the corrugated body can after manufacture the edge weld are inflated as a whole. - The perforations I6 are through the welds I7 relieved and can be used to put the foils in the desired position Order to stack.
