Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigtAn embodiment of the invention is shown in the drawing and is described in more detail below. It shows

F i g. 1 eine schematische isometrische Darstellung der Isolierbandage;F i g. 1 is a schematic isometric illustration of the insulating bandage;

Fig.2 eine schematische Schnittansicht eines Kältegefäßes mit der Isolierbandage.2 shows a schematic sectional view of a refrigeration vessel with the insulating bandage.

F i g. 1 zeigt eine schematische isometrische Darstellung eines Endes der mehrschichtigen Isolierbandage 10. Die Isolierbandage 10 weist eine wandferne Außenschicht 11 auf. Die Außenschicht 11 hat eine wandferne Seite 12 und eine wandnahe Seite 13. Die Breite der Außenschicht 11 entspricht der Höhe der Isolierbandage 10. Die Außenschichi erstreckt sich über die gesamte Höhe der Isolierbandage, wie in F i g. 1 dargestellt. Auf der wandfernen Seite 12 der wandfernen Außenschicht 11 ist ein Lamina! 15 angebracht, das im wesentlichen die eines »J« hat, d. h. sein einer Rand ist um 180° nach außen umgeschlagen, so daß ein Flansch 17 gebildet ist. Das Laminat 15 setzt sich aus einer Metallschicht 18, z. B. aus Aluminium und einer heißsiegelfähigen Schicht 19 zusammen. Diese kann z. B. ein Copolymerisat aus etwa 80% Äthylen und 20% Acrylsäure sein. Es können auch andere bekannte Klebstoffe, beispielsweise Epoxydkunstharze u.dgl. verwendet werden. An der wandnahen Seite 13 der Außenschicht 11 sind mehrere innere Teilschichten 21, 22, 23 und 24 aufeinanderliegend angefügt. Die Schichten 21,22,23 und 24 bedecken zusammen die wandnahe Seite 13 der Außenschicht 11. Auf dieser Seite ist zwischen der Außenschicht U und den Teilschichten 21, 22, 23 und 24 eine Mullschicht 26 zur Verstärkung angebracht, die über die Schichten 21 und 24 umgeschlagen ist. Vorzugsweise ist die Mullschicht 27 für die meisten Zwecke ein offenes Glasfasergewebe. Auf der von der Mullschicht 26 abliegenden Seite ist nuf den Schichten 21,22,23, 24 zweckmäßigerweise eine zweite Mullschicht 27 angebracht. Die aneinandergrenzenden Flächen der Schichten 21 und 22 sind nicht verbunden, sondern können sich ungehindert voneinander entfernen, wenn die Temperatur der inneren Teile an den vom Laminat 15 abgelegenen Stellen herabgesetzt wird. Die zweite Mullschicht 27 ist an den Schichten 21, 22, 23 und 24 an einer Stelle parallel zu und abgelegen von der Mullschicht 26 angebracht. Die Mullschicht 27 vermindert die Tendenz zur Rißbildung, wenn die Temperatur der die Mullschicht 27 tragendenF i g. 1 shows a schematic isometric illustration of one end of the multilayer insulating bandage 10. The insulating bandage 10 has an outer layer 11 remote from the wall. The outer layer 11 has a side 12 remote from the wall and a side 13 close to the wall. The width of the outer layer 11 corresponds to the height of the insulating bandage 10. The outer layer extends over the entire height of the insulating bandage, as in FIG. 1 shown. On the wall-remote side 12 of the wall-remote outer layer 11 is a lamina! 15 attached, which has essentially that of a "J", ie its one edge is turned 180 ° outwards, so that a flange 17 is formed. The laminate 15 is composed of a metal layer 18, e.g. B. made of aluminum and a heat-sealable layer 19 together. This can e.g. B. be a copolymer of about 80% ethylene and 20% acrylic acid. Other known adhesives such as epoxy resins and the like can also be used. On the side 13 of the outer layer 11 close to the wall, several inner sublayers 21, 22, 23 and 24 are attached one on top of the other. The layers 21, 22, 23 and 24 together cover the side 13 of the outer layer 11 close to the wall. On this side, a gauze layer 26 for reinforcement is attached between the outer layer U and the sub-layers 21, 22, 23 and 24, which over the layers 21 and 24 is turned over. Preferably, the gauze layer 27 is an open fiberglass fabric for most purposes. On the side remote from the gauze layer 26, a second gauze layer 27 is expediently attached to the layers 21, 22, 23, 24. The adjoining surfaces of the layers 21 and 22 are not connected, but can move away from one another unhindered when the temperature of the inner parts at the locations remote from the laminate 15 is reduced. The second layer of gauze 27 is attached to layers 21, 22, 23 and 24 at a location parallel to and remote from the layer of gauze 26. The gauze layer 27 reduces the tendency to crack when the temperature of those carrying the gauze layer 27

so Fläche reduziert wird. Zweckmäßigerweise ist die Mullschicht 27 an den Stellen geschlitzt, die den Grenzflächen zwischen den inneren Teilen entsprechen. In dem Laminat 15 sind mehrere querlaufende Riefen 29 geformt. Die Riefen 29 erstrecken sich bis zum J-förmigen Rand. Auf der Außenfläche des Laminates 15 sind entfernt von dem J-förmigen Umschlag mehrere fortlaufende Wülste eines heißklebenden Klebstoffes 31 angebracht.
F i g. 2 veranschaulicht schematisch eine Struktur, dieso area is reduced. The gauze layer 27 is expediently slotted at the points which correspond to the interfaces between the inner parts. A plurality of transverse grooves 29 are formed in the laminate 15. The grooves 29 extend to the J-shaped edge. On the outer surface of the laminate 15, remote from the J-shaped envelope, several continuous beads of a hot-melt adhesive 31 are attached.
F i g. 2 schematically illustrates a structure that

bo unter Verwendung der Isolierbandage gemäß Fig. 1 geschaffen ist. Die Struktur ist insgesamt mit 35 bezeichnet. Sie weist ein Kältegefäß 36 auf, das von einem im wesentlichen zylindrischen Isolaiionskörpcr 37 umgeben ist. Der zylindrische Isolationskörper 37 ist aus meh-bo using the insulating bandage according to FIG. 1 is created. The structure is denoted by 35 as a whole. It has a cold vessel 36 which is held by an im substantial cylindrical Isolaiionskkörcr 37 surrounded is. The cylindrical insulation body 37 is made of several

Dieser Flansch ist gegen dieti r > rercn turns of an insulation material 39 produced, which has a structure according to FIG. 1 has. Each turn has a flange 41 which corresponds to the flange 17 bent downwards. This flange is against the

äußere Lage der nächstunteren Windung platt gedrückt und abgedichtet, so daß eine praktisch flüssigkeitsdichte Außenfläche entsteht.outer layer of the next lower turn pressed flat and sealed, so that a practically liquid-tight External surface is created.

Wenn man eine Isolation gemäß der Erfindung herstellt erstrecken sich die Riefen, etwa die Riefen 29 in Fig. 1, teilweise über das Laminat und sorgen für eine gesteuerte Ausbeulung des metallischen Laminates, wenn der Streifen auf eine Außenfläche, etwa eine sphärische Fläche, gewickelt wird. Die gesteuerte Ausbeulung infolge der Riefen liefert eine verhältnismäßig seichte Vertiefung, die in regelmäßigen Abständen auftritt Vorzugsweise ist die Menge des heißklebenden Klebstoffes 31, etwa ein Streifen von Bitumen, eines Äthylen-Acrylsäure-Copolymerisates oder eines Äthylen-Vinylacetat-Copolymerisates, groß genug, daß beim Heißverschweißen des Außenelementes mit dem benachbarten Streifen, wie in F i g. 2 angedeutet, die flachen Vertiefungen, die den Riefen entsprechen, ausgefüllt werden und man eine flüssigkeitsfeste Außenfläche erhält.When making insulation in accordance with the invention, the grooves extend, such as grooves 29 in FIG Fig. 1, partially across the laminate and provide a controlled bulging of the metallic laminate when the strip hits an outer surface, for example a spherical one Surface that is wrapped. The controlled bulging as a result of the grooves provides a relatively shallow depression that occurs at regular intervals Preferably the amount of heat adhesive Adhesive 31, such as a strip of bitumen, an ethylene-acrylic acid copolymer or an ethylene-vinyl acetate copolymer, large enough that when the outer element is heat-welded to the adjacent strip, as in FIG. 2 indicated, the flat Depressions that correspond to the grooves are filled and you have a liquid-proof outer surface receives.

Besonders zweckmäßige Isofationskörper gemäß der Erfindung erhält man, wenn man geschlossenzellige thermoplastische Schaumstoffe verwendet, wie beispielsweise Polystyrol-Schaumstoff, thermoplastischer Polyurethan-Schaumstoff, Polyvinylchlorid-Schaumstoff, Polyolefin-Schaumstoff, etwa Polyäthylen-Schaumstoff und Polypropylen-Schaumstoff mit geschlossener Zellstruktur. Nach Wunsch kann man auch verschiedenartige Schaumstoffe verwenden.Particularly useful Isofationskörper according to Invention is obtained using closed cell thermoplastic foams such as Polystyrene foam, thermoplastic polyurethane foam, polyvinyl chloride foam, Polyolefin foam, such as polyethylene foam and polypropylene foam with closed Cell structure. A variety of foams can be used if desired.
