Es waere daher aeusserst wuenschenswert, ueber ein Verfahren zur Formung derartiger Artikel verfuegen zu koennen, welches wesentlich einfacher, wirtschaftlicher und vor allein leichter ausfuehrbar ist, um die Produktionsbedingungen zu verbessern. Es ist die Hauptaufgabe der Erfindung, ein derartiges vereinfachtes Verfahren zu schilf fen.It would therefore be extremely desirable to have a method for molding such articles which is much easier, more economical and more than alone is easier to implement in order to improve production conditions. It is the main object of the invention to be a such a simplified procedure to reed.

Ferner hat sich die Erfindung die Aufgabe gestellt, ein Formpressverfahren zur Erzeugung der besagten Artikel in Vor— schlag zu bringen, welches vor allem bei Verwendung von Kunststoffen, wie in erster Linie Polyvinylchlorid, als biegsamer Werkstoff zur Bildung der Schichten der Artikel geeignet und zweckmaessig ist.Furthermore, the invention has set itself the task of a To bring compression molding process for the production of said articles in the proposal, which especially when using Plastics, such as primarily polyvinyl chloride, as flexible material for forming the layers of the article is suitable and expedient.

Zur Loesung dieser Aufgabe schlaegt die Erfindung ein Verfahren zur Bildung von mehrschichtigen Erzeugnissen, mit mindestens zwei Schichten aus elastischen biegsamen Werkstoffen und Lufteinschluessen zwischen den Schichten, innerhalb einer Form vor, welches durch die folgenden Verfahrensschritte gekennzeichnet ist: Folien der besagten Werkstoffe werden Seite gegen Seite in gegenseitige Beruehrung gebracht, wobei mindestens eine der Beruehrungsflaechen gaufriert ist; in der Beruehrungszone der Folien wia-d Kur TVildutig der Lufteinschlucsse ein Luftstrom durchTo solve this problem, the invention strikes Process for the formation of multi-layer products, with at least two layers of elastic, flexible materials and air pockets between the layers, within a mold, produced by the following process steps is marked: foils of the said Materials are brought into mutual contact side by side, with at least one of the contact surfaces is embossed; in the contact zone of the foils wia-d Kur TVildig air flow through the air pockets

Entlang des Umfanges ist der Pressenstempel 12 mit einer Trennschweissvorrichtung versehen, die eine ebenfalls an den Hochfrequenzgenerator angeschlossene Elektrode I7 und ein beweglich am Stempel angeordnetes Schneidmesser 19 umfasst, Wie die Figur 1 zeigt, werden auf den Formboden 11 zwei Folien 20, 21 aus biegsamen Kunststoff, beispielsweise PVC, ueboroinander gelegt, wobei die untere Folie 20 an ihrer oberen Flaeehe gaufriert ist, so dass die Boruehrung zwischen den beiden Folien diskontinuierlich ist.Π π don die Ausm'liiiiu.ujycMi 13 uiiigobonclon Zonori are on Prossensteinpel 12 Schweisselekfcroden 16 arranged on A high frequency generator is connected. The press ram 12 is provided with a separating welding device along the circumference provided, which is also connected to the high-frequency generator electrode I7 and a movable comprises cutting knife 19 arranged on the punch, As FIG. 1 shows, two are placed on the mold bottom 11 Sheets 20, 21 made of flexible plastic, for example PVC, laid one on top of the other, with the lower film 20 attached its upper surface is embossed, so that the Boruehrung is discontinuous between the two foils.

Zur Erzeugung des Artikels wird der Pressenstempel 12 bis zur AufIngo auf don auf dom Formbodon 11 liegenden Folien abgesenkt (siehe Figur 1), wonach die Vakuumpumpe in Betrieb gesetzt wird. Auf diese Yeise wird durch die Kanae-Ie Ik die Luft aus den Atisnohmungen I3 abgesaugt, wodurch von aussen Luft in die Beruehrungszone zwischen den beiden Folien 20, 2 1 oinstroomt, was durch die diskontinuierliche Beruehruiig der beiden Folien ermoeglicht wird. Dies hat zur Folge, dass sich die obere Folie 21 an den Stellen der Ausnehmungen I3 aufblaeht (wie durch die strichpunktierten Liηion in Figur 1 veranschaulicht ist) und sich Lufteinschluesso 22 bilden, die in ihrer Form jener der Ausnehmungen 13 entsprechen. Ihre Geometrie und Abmessungen sowie der Luftdruck in ihnen koennen daher verschieden gewaehlt wer-To produce the article, the press ram 12 is lowered to the top of the foils lying on the Formbodon 11 (see FIG. 1), after which the vacuum pump is put into operation. In this Yeise the air is aspirated from the Atisnohmungen I3 through the Kanae-Ie Ik, which oinstroomt from the outside air into the Beruehrungszone between the two films 20, 2 1, which is made possible by the discontinuous Beruehruiig of the two films. The consequence of this is that the upper film 21 expands at the locations of the recesses I3 (as illustrated by the dash-dotted lines in FIG. 1) and air inclusions 22 are formed, the shape of which corresponds to that of the recesses 13. Their geometry and dimensions as well as the air pressure in them can therefore be chosen differently.

Das erfindungsgemaesse Verfahren kann je nach den Produkfcionsorf ordorni rsoij auch automatisiert werden. Die beim Verfahren anwendbaren biegsamen Kunststoffe koemien aus einer ziemlich xveiten Vielzahl ausgewaehlt werden. Insbesondere ist die Verwendung von PVC vorzuziehen, wobei die Werkstoffe auch mit jeglicher Art von Geweben kombiniert werden koonnen, um den fertigen Erzeugnissen fuer die vorschrioclonsten Anwendungen die geeignetsten 'Eigenschaften verleihen.The inventive method can depending on the producfcionsorf ordorni rsoij can also be automated. The flexible plastics that can be used in the process can be selected from a fairly wide variety. In particular, the use of PVC is preferable, the materials also being made with any type of fabric can be combined to give the finished product the most suitable properties for the most prescribed applications to lend.

So eignet sich das erfindungsgemaesse Verfahren beispielsweise zur Erzeugung von Einlagesohlen, Sohlen, Oberleder, inneren und aeusseren Verkleidungen fuer jede Art von Schuhwerk, von industriellen Polsterungen, Poelstern, Matrazzen, zum Beispiel fuer sanitaeren Gebrauch, von Spielzeugen, Sportartikeln u.a.m.For example, the method according to the invention is suitable for the production of insoles, soles, upper leather, inner and outer coverings for every kind of footwear, of industrial upholstery, poelstars, mattresses, for example for sanitary use, of Toys, sporting goods, etc.
