The preparation of the tube body 5 is carried out using the layers 7.1 - 7.3 having sheet-like film composite material or sheet 8 (Figure 2 and 3), From the starting or sheet 8, which is withdrawn, for example, from a supply roll, a shaped body 10 is formed, and Although by rolling the starting or flat material 8 to a tubular or cylindrical body and by connecting the after rolling adjacent longitudinal sides of the Fiachmaterials 8 along a connecting or welding seam 9. The formation of the tubular or cylindrical shaped body 9, for example, takes place continuously with the Pulling the starting or Fiachmaterials from the supply roll, in which case the rolling takes place at least one oriented in the web longitudinal direction axis. In principle, it is also possible to separate blanks from the flat material, from which then the respective shaped body is formed, wherein the curling can also take place here about axes perpendicular to the web longitudinal direction. In detail, the connection to the connecting or welding seam 9 takes place in accordance with the representation of FIG. 5 by butt welding in such a way that at least each layer consisting of plastic, for example the

Schichten 7.1 und 7.3 an den Längsrändern 8.1 des zu dem schlauchförmigen Formkörper 10 geformten Flachmaterials jeweils mit sich selbst stumpf verbunden sind, also die Verbindungs- und Schweißnaht 9 von einer stumpfen und nicht von einer überlappenden Verbindung gebildet ist. Weiterhin liegen die Randbereich der beispielsweise aus dem metallischen Material gebildeten Schicht 7.2 an der Verbindungs- oder Schweißnaht zumindest stumpf gegeneinander an. Um die Schweißverbindung bzw. Verbindungs- oder Schweißnaht 9 zu sichern, wird bei der dargestellten Ausführungsform auf die Innenfläche des Formkörpers 10 oder auf die Innenfläche der die jeweilige Tubenkörperwand 7 bildenden Längen 1 1 des Formkörpers 10 ein die Verbindungs- oder Schweißnaht 9 überlappendes Band aufgebracht, weiches sich über die gesamte Länge des Formkörpers 10 bzw. des Tubenkörpers erstreckt. Das Band 12 dient einerseits zur mechanischen Sicherung, d.h. zur Verstärkung der Verbindungs- oder Schweißnaht 9 in der Weise, dass auch bei erhöhten Belastungen der Tube 1 , d.h. bei einem erhöhten auf die Innenfläche des Tubenkörpers 5 ausgeübten Kräften oder Drücken, wie sie beispielsweise auch bereits bei dem üblichen Gebrauch der Tube 1 bzw. beim Ausdrücken des Tubeninhalts über die geöffnete Tubenöffnung auftreten und einen erhöhten Tubeninnendruck erzeugen, nicht öffnet. Der so hergestellte Formkörper 10 oder Längen 1 1 dieses Formkörpers 10 werden dann zur Komplettierung der Tube 1 mit dem Tubenelement 2 verbunden. Layers 7.1 and 7.3 at the longitudinal edges 8.1 of the tubular shaped body 10 shaped flat material are each butt-joined to themselves, so the connection and weld 9 is formed by a blunt and not by an overlapping connection. Furthermore, the edge region of the layer 7.2, formed, for example, from the metallic material, abuts against one another at the joining or welding seam, at least in a blunt manner. In order to secure the welded connection or connecting or welding seam 9, in the embodiment shown, the length of the inner tube of the molded body 10 or of the inner surface of the respective tube body wall 7 is formed 1 1 of the molded body 10 applied to the connection or weld 9 overlapping band, which extends over the entire length of the molding 10 and the tube body. The band 12 serves on the one hand for mechanical securing, ie for reinforcing the connecting or welding seam 9 in such a way that even at increased loads of the tube 1, ie at an increased forces or pressures exerted on the inner surface of the tube body 5, as for example already occur during the usual use of the tube 1 or when expressing the tube contents on the open tube opening and produce an elevated internal tube pressure does not open. The molded body 10 produced in this way or lengths 1 1 of this shaped body 10 are then connected to the tube element 2 to complete the tube 1.

Mit dem Aufbringen des Bandes 12 wird aber gleichzeitig eine zusätzliche With the application of the tape 12 but at the same time an additional

Abdichtung oder Versiegelung von eventuell noch verbliebenen Leckagen im Bereich der Verbindungs- oder Schweißnaht 9 erreicht. Hierfür ist das Band 12 wenigstens zweilagig ausgeführt, und zwar bestehend aus einer ersten Lage 12.1 , die nach dem Aufbringen des Bandes 12 die dem Tubenkörperinnenraum zugewandte Seite dieses Bandes bildet und die mechanische Festigkeit garantiert, und aus einer Lage 12.2, die die Verbindung zwischen dem Band 12 und dem Formkörper 10 bewirkt und eventuell verbliebene Leckagen im Bereich der Verbindungs- oder Schweißnaht 9 verschließt bzw. versiegelt, wie die mit 12.3 angedeutet ist. Das Aufbringen des Bandes erfolgt thermisch. Hierfür besteht die Schicht 12.1 aus einem thermoplastischen Kunststoff, der bei der beim Aufbringen des Bandes 12 verwendeten Temperatur in einem flüssigen oder zähflüssigen Zustand übergeht, sodass mit der Schicht 12.2 nicht nur die Verbindung des Bandes 12 mit dem Formkörper 10 erreicht wird, sondern das verflüssigte Material der Schicht 12.2 zugleich durch Kapillarwirkung in eventuell bestehende Leckagen oder Spalte im Bereich der Verbindungs- oder Schweißnaht 9 eindringt, so dass nach dem Abkühlen diese Leckagen durch die Versiegelung 1 2.3 zuverlässig verschlossen sind. Insbesondere wird mit dem Material der Schicht 1 2.2 auch ein Verschließen eines eventuell bestehenden Spaltes zwischen den beiden einander benachbarten Rändern der Schicht 7.2 erreicht, die (Ränder) nur dicht oder stumpf gegeneinander anliegen, aber wegen des für diese Schicht 7.2 verwendeten Materials nicht materialschlüssig mit einender verbunden sind, Die Schicht 12.1 besteht beispielsweise ebenfalls aus Kunststoff, z.B. aus thermoplastischem Sealing or sealing of any remaining leaks in the connection or weld 9 achieved. For this purpose, the band 12 is performed at least two layers, consisting of a first layer 12.1, which forms the tube body interior facing the side of this band after application of the band 12 and the mechanical strength guarantees, and from a layer 12.2, the connection between the Band 12 and the molded body 10 causes and possibly remaining leaks in the connection or weld seam 9 closes or sealed, as indicated by 12.3. The application of the tape is thermal. For this purpose, the layer 12.1 consists of a thermoplastic material, which merges at the temperature used in applying the tape 12 in a liquid or viscous state, so that not only the connection of the strip 12 with the molding 10 is achieved with the layer 12.2, but the liquefied Material of the layer 12.2 at the same time penetrates by capillary action in any existing leaks or gaps in the region of the connection or weld seam 9, so that after cooling these leakages are reliably closed by the seal 1 2.3. In particular, with the material of the layer 1 2.2, closing of a possibly existing gap between the two adjoining edges of the layer 7.2 is achieved, which (edges) lie only tightly or dull against each other, but because of the used for this layer 7.2 Material are not materially connected with einender, The layer 12.1 is also made of plastic, for example, for example, thermoplastic

Kunststoff, wobei allerdings der Kunststoff für die Schicht 12.1 so ausgewählt ist, dass er bei der Verarbeitungstemperatur noch nicht in dem schmelzflüssigen Zustand übergeht, d.h. der Kunststoff der Schicht 12.1 einen gegenüber der Schicht 12,2 höheren Schmelzpunkt aufweist. Plastic, wherein, however, the plastic for the layer 12.1 is selected so that it does not change to the molten state at the processing temperature, i. the plastic of the layer 12.1 has a higher melting point than the layer 12.2.

Vorstehend wurde davon ausgegangen, dass das Band 12 auf die Innenfläche des Formkörpers 10 bzw. der durch Abtrennen aus dem Formkörper erzeugten Längen 1 1 aufgebracht wird. Es besteht aber auch die Möglichkeit, das Band 12 auch auf die Außenseite des Formkörpers 10 oder der Längen 1 1 die Verbindungs- oderIt has been assumed above that the tape 12 is applied to the inner surface of the molded body 10 or the lengths 1 1 produced by separation from the molded body. But it is also possible, the tape 12 also on the outside of the molded body 10 or the length 1 1 the connection or

Schweißnaht 9 überlappend aufzubringen, und zwar wiederum durch Erhitzen und Verflüssigen der dann gegen die Außenfläche des Formkörpers 10 anliegenden Schicht 12,2, wobei das Material dieser Schicht durch Kapillarwirkung in eventuell vorhandene Leckagen oder Spalten im Bereich der Verbindungs- oder Schweißnaht 9 eintritt und diese Leckagen verschließt. Weiterhin besteht die Möglichkeit, sowohl auf die Außenseite als auch auf die Innenseite des jeweiligen Formkörpers 10 das die Verbindungs- oder Schweißnaht 9 überlappende Band 12 aufzubringen, Apply weld 9 overlapping, in turn by heating and liquefying the then abutting against the outer surface of the molding 10 layer 12.2, the material of this layer enters by capillary action in any leaks or gaps in the region of the connecting or welding seam 9 and this Leakage closes. Furthermore, it is possible, both on the outside and on the inside of the respective shaped body 10 to apply the connecting or welding seam 9 overlapping band 12,

Vorstehend wurde davon ausgegangen, dass das Versiegeln der Verbindung bzw. Verbindungs- oder Längsnaht 9, d.h. das dichte Verschließen eventueller im Bereich der Verbindung verbliebener Spalten oder Leckagen, insbesondere auch das dichte Verschließen des Übergangs zwischen den nicht materialschlüssig verbundenen Enden der Schicht 7.2 unter Verwendung des Bandes 12 erfolgt. Beispielsweise dann, wenn auf die mechanische Verstärkungsfunktion des die Verbindung 9 überlappenden Bandes 12 verzichtet werden kann, ist es auch möglich, das die Versiegelung bildende Material, beispielsweise das die Versiegelung bewirkende thermoplastische Kunststoffmaierial entlang der Verbindung 9 streifenförmig bereit zu stellen, beispielsweise in Form eines von einem Vorrat abgezogenen It has heretofore been assumed that the sealing of the connection or longitudinal seam 9, i. the tight closure of any gaps or leaks remaining in the region of the connection, in particular the tight closing of the transition between the non-materially connected ends of the layer 7.2 using the strip 12, takes place. For example, if the mechanical reinforcing function of the band 9 overlapping the connection 9 can be dispensed with, it is also possible to provide the material forming the seal, for example the thermoplastic plastic material causing the sealing, strip-shaped along the connection 9, for example in the form of a withdrawn from a supply

bandförmigen Materials oder durch Aufspritzen eines die Versiegelung band-shaped material or by spraying a the seal

bewirkenden Materials und durch anschließendes Erhitzen dieses Materials oder aber durch Aufbringen eines bereits flüssigen und nach dem Eindringen in eventuelle Leckagen der Verbindung 9 dort, erstarrenden Materials. Weiterhin besteht auch die Möglichkeit, auf den Formkörper 10 oder auf die jeweilige Formkörperlänge 1 1 z.B. durch Umspritzen ein Material aufzubringen, welches den Formkörper 10 oder die jeweilige Formkörperlänge 1 1 auf dem gesamten Umfang umschließt und welches dann zusätzlich z.B. durch erneutes Erhitzen die Versiegelung 12.3 der Verbindung bewirkt. Diese Ummantelung 13, die dann beispielsweise zugleich auch als eine Art„Urnreifung" den Tubenkörper 5 im Bereich der Verbindung 9 mechanisch verstärkt, kann auch mehrlagig ausgeführt sein, beispielsweise mit einer an die Tubenkörperwand 7 unmittelbar causing material and by subsequent heating of this material or by applying an already liquid and after penetrating into possible leaks of the compound 9 there, solidifying material. Furthermore, it is also possible to apply to the molding 10 or to the respective molding body length 1 1, for example by encapsulating a material which encloses the molding 10 or the respective molding body length 1 1 on the entire circumference and which then additionally, for example by re-heating the seal 12.3 causes the connection. This sheath 13, which then mechanically reinforced, for example, at the same time as a kind of "Urnreifung" the tube body 5 in the region of the compound 9, may also be designed in several layers, for example with a directly to the tube body wall 7

anschließenden inneren Lage aus einem thermoplastischen Kunststoffmaterial mit niedrigem Schmelzpunkt und aus einer äußeren Lage aus einem thermoplastischen Kunststoff mit höherem Schmelzpunkt. subsequent inner layer of a thermoplastic material with a low melting point and an outer layer of a thermoplastic material with a higher melting point.

Weiterhin besteht die Möglichkeit, die Verbindung 9 an einer Seite des Furthermore, it is possible to connect 9 on one side of the

Tubenkörpers 5 durch eine die Verbindung überlappendes Band oder durch ein den schlauchförmigen Körper 10 oder die jeweilige Form kör per länge 1 1 am gesamten Umfang umschließende, eine Umreifung bildende, wenigstens einlagige Schicht zu verstärken und von der anderen Seite des Tubenkörpers 5 her mit einem geeigneten Material, beispielsweise mit einem thermoplastischen Kunststoffmaterial die Versiegelung der Verbindung 9 vorzunehmen. Tube body 5 by a compound overlapping the band or by the tubular body 10 or the respective shape kör per length 1 1 on the entire circumference surrounding, forming a strapping, at least single-layer strengthen and from the other side of the tube body 5 ago with a suitable Material, for example, with a thermoplastic plastic material to make the sealing of the compound 9.
