Verfahren zur Herstellung wärme- und schallisolierter Leitungsrohre
Zusatz zu Patent  (Patentanmeldung P 19 60 932)Process for the production of heat and sound insulated conduits
Addendum to patent (patent application P 19 60 932)
Das Hauptpaptent betrifft ein Verfahren zur Herstellung wärme- und schallisolierter Leitungsrohre, bestehend aus einem Metallrohr,vorzugsweise aus Kupfer, einer Schaumstoffisolierungund einem Außenmantel, bei dem auf das Metallrohr eine Abstandshalterwendel, vorzugsweise aus Papier, aufgebrachtwird, um die Abstandshalterwendel ein längseinlaufendes Band zum Schlitzrohr geformt wird, in das noch offene Schlitzrohrein selbstschäumender Kunststoff eingebracht wird undanschließend die Bandkanten miteinander verbunden werden.The main patent concerns a process for the production of heat and sound-insulated conduit pipes, consisting of a metal pipe,preferably made of copper, a foam insulationand an outer jacket, in which a spacer coil, preferably made of paper, is applied to the metal tubeis formed around the spacer coil a longitudinal band to the slotted tube, in the still open slotted tubea self-foaming plastic is introduced andthen the tape edges are connected to one another.
Nach einer besonders günstigen Weiterbildung dieses Patentes wird auf das Band nach dem Aushärten der Schaumstoffschichtein Außenmantel aus einem Copolymer aufextrudiert.According to a particularly favorable further development of this patent, the foam layer is applied to the tape after the hardeningan outer jacket made of a copolymer is extruded on.
Der wesentliche Vorteil der Erfindung ist darin zu sehen,daß die aufextrudierte Copolymerschicht mit dem Band innigverklebt, so daß sich das so hergestellte Rohr bereitwillig biegen läßt, ohne daß bei Verwendung eines flexiblen Schaumesdas bisher als Außenmantel verwendete Band einknickt, was unter Umständen zu einer Beschädigung des Außenmantelsführen könnte. Es ist somit gelungen, große Längen eines derartigen Leitungsrohres zu Ringbunden zu wickeln.The main advantage of the invention is to be seen inthat the coextruded copolymer layer is intimate with the tapeglued, so that the pipe produced in this way can readily be bent without the use of a flexible foamthe tape previously used as the outer jacket buckles, which may damage the outer jacketcould lead. It has thus been possible to wind large lengths of such a conduit pipe into coils.
Die Erfindung ist an Hand des in der Figur schematisch dargestalltenAusführungsbeispiels näher erläutert. Um einKupferrohr 1 ist zum Zweck der Wärme- oder Schallisolierung eine Schicht 12 aus einem flexiblen Polyurethanschaum aufgebracht.ALs Form fürdenSchaumstoff dient während des Auf-The invention is explained in more detail with reference to the embodiment shown schematically in the figure. A layer 12 made of a flexible polyurethane foam is applied around a copper pipe 1 for the purpose of heat or sound insulation. The form forthe foam is used during assembly

Schäumens ein Band 7 bzw. eine Folie. Als vorteilhaft haben sich Folien aus Polyvinylchlorid erwiesen, es können aberauch dünne Metallfolien verwendet werden. Auf dieses Band 7 wird nach dem Aushärten der Schaumstoffschicht 12 einMantel 13 aus einem für die Verklebung geeigneten Copolymer des Äthylens oder eines Copolymers auf der Basisvon Vinylchlorid aufextrudiert. Dieser Mantel 13 verklebtauf Grund seines chemischen Aufbaus atfe Innigste mit demBand 7» so daß das Leitungsrohr leicht gebogen werden kann, ohne daß das Band 7 einknickt. Mit 4 ist eine Abstandshalterwendel,beispielsweise aus Polyurethan, bezeichnet, die das Band 7 auf gleichen Abstand zum Kupferrohr 1 hält.Da ein flexibler Schaumstoff nicht lichtbeständig ist, kann es von Vorteil sein, das Band 7 oder die Copolymerschicht13 in bekannter Weise lichtundurchlässig zu machen,beispielsweise durch Pigmentierung des Copolymers oder durch nachträgliches Aufbringen einer lichtundurchlässigen Lackschicht.Foaming a tape 7 or a film. Films made of polyvinyl chloride have proven to be advantageous, but they canthin metal foils can also be used. After curing, the foam layer 12 is applied to this tape 7Jacket 13 made of a copolymer of ethylene suitable for bonding or a copolymer based on itextruded from vinyl chloride. This jacket 13 is gluedBecause of its chemical structure, feel most intimate with himBand 7 »so that the conduit can be bent easily without the band 7 buckling. With 4 is a spacer coil,for example made of polyurethane, which keeps the band 7 at the same distance from the copper pipe 1.Since a flexible foam is not lightfast, it can be advantageous to use the tape 7 or the copolymer layer13 to make opaque in a known manner,for example by pigmenting the copolymer or by subsequently applying an opaque lacquer layer.
