Bei der Herstellung von für den Transport von Flüssigkeiten oder auch Gasen bestimmten zusammenroll- oder -faltbaren Druckschläuchen auf Basis natürlicher oder synthetischer Gummisorten wird üblicherweise so verfahren, daß ein vorvulkanisierter Gummischlauch in einen durch Weben, Wirken oder Klöppeln aus natürlichen oder künstlichen Fasern hergestellten Schlauchmantel lose eingezogen und dann mittels Durchleitung von überhitztem Wasserdampf ausvulkanisiert und gleichzeitig haftfest mit dem Schlauchmantel verbunden wird.In the manufacture of rolled-up materials intended for the transport of liquids or gases or -foldable pressure hoses based on natural or synthetic rubber types usually proceed so that a pre-vulcanized rubber hose in one by weaving, knitting or Tubular sheath made of natural or artificial fibers is loosely drawn in and then vulcanized through the passage of superheated steam and at the same time firmly adhered to it the hose jacket is connected.
In der gleichen Weise wird auch bei einem bekannten Verfahren zur Herstellung von gewebearmierten Schläuchen mit einem Schlauchmantel aus natürlichen oder synthetischen Fasern und einer Innenauskleidung aus linearem Polyester vorgegangen. Dabei wird die Innenauskleidung aus einer Polyesterfolie hergestellt, die einseitig mit Polyäthylen beschichtet ist. Diese dublierte Folie wird zunächst so zusammengerollt, daß ihre seitlichen Ränder aneinanderstoßen, woraufhin diese dann mittels eines zusätzlichen Folienstreifens miteinander verbunden werden, so daß ein Schlauch entsteht, bei dem die polyäthylenbeschichtete Seite die Außen- und die Polyesterseite die Innenwand bildet. Nach Einbringung dieses vorgefertigten Schlauches in den durch Weben, Wirken od. dgl. ebenfalls vorgefertigten Schlauchmantel wird durch Einleitung überhitzten Wasserdampfes in das Innere des Innenschlauches dessen Polyäthylenschicht plastifiziert und an die Innenseite des Schlauchmantels angepreßt, wodurch sich eine haftfeste Verbindung zwischen Innenschlauch und Schlauchmantel ergibt.In the same way is also in a known process for the production of fabric-reinforced Hoses with a hose jacket made of natural or synthetic fibers and a Lining made of linear polyester proceeded. The inner lining is made of a Made of polyester film, which is coated on one side with polyethylene. This duplicated slide will first rolled up so that their side edges butt against each other, whereupon these then be connected to one another by means of an additional film strip, so that a tube is formed at where the polyethylene-coated side forms the outer wall and the polyester side forms the inner wall. To Introduction of this prefabricated hose into the one also prefabricated by weaving, knitting or the like Hose jacket is created by introducing superheated steam into the interior of the inner hose whose polyethylene layer is plasticized and pressed against the inside of the hose jacket, which results in a firm connection between the inner hose and the hose jacket.
Nach diesem Verfahren lassen sich auch Schlauchkombinationen mit einem Kunststoffinnenschlauch auf Polyamidbasis erzielen, wobei dieser in Form eines wiederum vorgefertigten dünnwandigen Folienrohres in den Schlauchmantel eingezogen und unter Zugabe eines geeigneten wärmeaktivierbaren Haftvermittlers zwischen die Außenfläche des Folienrohres und die Innenfläche des Schlauchmantels sowie unter Anwendung von Druck und Hitze mit dem Schlauchmantel haftfest verbunden wird.This method can also be used to create hose combinations with a plastic inner hose Achieve based on polyamide, this in turn in the form of a prefabricated thin-walled film tube drawn into the hose jacket and with the addition of a suitable heat-activated adhesion promoter between the outer surface of the foil tube and the inner surface of the hose jacket and is firmly bonded to the hose jacket using pressure and heat.
Sowohl bei den linearen Polyesterfolien als auch bei den Folien auf Polyamidbasis, wie sie bei diesen
Schlauchkombinationen in Form von vorgefertigten Innenschläuchen Verwendung finden, handelt es sich
um zwar flexible, aber dennoch relativ starre Materialien, die weder eine gummielastische Konsistenz
aufweisen noch bei den zur Anwendung kommenden, unterhalb des Schmelzpunktes der Produkte
liegenden Temperaturen eine Plastifizierung erfahren, Verfahren zum Herstellen von flexiblen

Fasern hergestellten Schlauchmantel und einer

so vielmehr relativ starre Konsistenz beibehalten. Innenschläuche aus diesen Materialien machen daher zwar eine etwa durch Rollen, Falten od. dgl. verursachte Dehnung des elastischen Schlauchmantels mit, im Gegensatz zu diesem stellt sich bei ihnen die Dehnung jedoch nicht mehr zurück. Daher kommt es, daß in der Verbindungsfläche zwischen Innenschlauch und Schlauchmantel Spannungen auftreten, die nicht nur eine Ablösung der beiden Schlauchteile voneinander, sondern auch eine Knickbeanspruchung des gegenüber dem Schlauchmantel länger gewordenen Innenschlauches zur Folge haben können, die mit der Zeit — insbesondere bei weiterem wiederholtem Rollen oder Falten der Schlauchkombination — schließlich zum Bruch führt.so rather maintain a relatively rigid consistency. Inner tubes therefore make of these materials one caused by rolling, folding or the like Stretching of the elastic hose jacket, in contrast to this, the stretching occurs with them but no longer back. Hence it happens that in the joint area between the inner tube and hose jacket tensions occur, which not only cause the two hose parts to become detached from each other, but also a buckling load on the hose that has become longer than the hose jacket Inner tube can have the consequence over time - especially with further repeated Rolling or folding the hose combination - ultimately leads to breakage.
Zwar ist es nach diesem bekannten Verfahren auch möglich, Schlauchkombinationen aus einem aus natürlichen oder künstlichen Fasern durch Weben, Wirken od. dgl. hergestellten Schlauchmantel und einer dünnwandigen Innenauskleidung aus gummielastischem Kunststoff, beispielsweise aus weichgestelltem Polyvinylchlorid oder Polyurethan, also aus solchem Material herzustellen, das sowohl eine Dehnung des Schlauchmantels als auch deren Rückbildung mitmacht und demgemäß die vorstehend genannten Nachteile vermeidet. Dabei gestaltet sich jedoch der Herstellungsvorgang insofern äußerst schwierig, als diese Materialien durch Wärmeeinwirkung in den thermoplastischen Bereich übergeführt werden, dabei mit zunehmender Temperaturbelastung zusehends ihre Zähigkeit verlieren und schließlich in den zähflüssigen thermoplastischen Zustand übergehen, was erforderlich macht, daß bei genau defi-Although it is also possible according to this known method, hose combinations from one from natural or artificial fibers by weaving, knitting od.

In this respect, however, the manufacturing process turns out to be extremely high difficult when these materials are converted into the thermoplastic area by the action of heat lose their toughness with increasing temperature load and finally pass into the viscous thermoplastic state, which makes it necessary that with exactly defi-
