Description
leitung. Ihre Länge ist so gewählt, daß die Öffnung 6 a in einen an den Hohldornen 5, 6, 7, 8 entlanggeführten Hohlkörper 9 erst dann hineinragt, wenn der Hohlkörper 9 hinreichend ausgehärtet ist. Der neben dem Hohldorn 5 für die Druckluft vorgesehene dritte Hohldorn 8 kann Spülluft für den ausgehärteten Hohlkörper 9 führen; durch sie kann jedoch auch das bei der Abfüllung von kohlensäurehaltigen Getränken erforderliche CO2 in den Hohlkörper 9 hineingedrückt werden. Die Öffnung 8 α des Hohldoms 8 ist so angebracht, daß die in den Hohlräumen 4 sich längs der Hohldorne 5, 6, 7, 8 bewegenden Hohlkörper 9 erst diese Öffnung 8 α überfahren, bevor sie zu der Öffnung 7 α des Hohldoms 7 gelangen. Der Hohldom 7 führt das Füllgut, z. B. Milch, Bier od. dgl. zu. Durch die Verteilung der Öffnungen la und 8 α wird erreicht, daß der Hohlkörper 9 gespült bzw. mit CO2 gefüllt ist, bevor das Füllgut in ihn eintritt. Außer den Hohldornen 5, 6, 7, 8 können beliebige weitere Leitungen vorgesehen sein, um z. B. sowohl zu spülen als auch mit CO2 zu füllen.management. Their length is chosen such that the opening 6a in a guided along the hollow mandrels 5, 6, 7, 8 hollow body 9 only protrudes, if the hollow body 9 is sufficiently cured. The third hollow mandrel 8 provided for the compressed air in addition to the hollow mandrel 5 can carry scavenging air for the cured hollow body 9; however, they can also be used to press the CO 2 required for filling carbonated beverages into the hollow body 9. The opening 8 α of the hollow dome 8 is attached so that extending along the hollow mandrels 5, 6, 7, 8 moving hollow body 9 until this opening 8 run over α in the cavities 4 before α to the opening 7 of the hollow dome 7 enter. The hollow dome 7 leads the filling material, for. B. milk, beer or the like. To. By distributing the openings la and 8 α it is achieved that the hollow body is flushed 9 and filled with CO 2 before the medium enters it. In addition to the hollow mandrels 5, 6, 7, 8, any other lines can be provided to, for. B. both to flush and to fill with CO 2.
Das Hals- und Bodenstück der Formteile 3 ist auf der Ober- und Unterseite mit je einer freien Vertiefung 10,11 versehen, die der Bildung von Standflächen 12 bei dem fertigen Hohlkörper 9 dient. Außer den Vertiefungen 10 und 11 sind die Formteile 3 auf ihrer Innenseite mit ringsum laufenden Rillen 13 versehen. Diese Rillen 13 deuten in dem dargestellten Beispiel Faßbänder an, die die Aufmachung eines Fäßchens vervollständigen.The neck and bottom pieces of the molded parts 3 are each with a free recess on the top and bottom 10, 11, which is used to form standing surfaces 12 in the finished hollow body 9. In addition to the recesses 10 and 11, the molded parts 3 are running all around on their inside Grooves 13 provided. In the example shown, these grooves 13 indicate tapes that define the presentation of a vial to complete.
ίο Die Hals- und Bodenstücke der Formteile 3 weisen an den bogenförmigen Partien der Formausnehmung Schweißtrennkanten 14 auf, die den Hohlkörper 9 in diesem Bereich freischneiden. Die Hohlkörper 9 hängen lediglich über Röhrchen 20 aneinander, welche beim Aufblasen des Kunststoffschlauchs 2 während seines Entlangfahrens an den Hohldomen 5, 6, 7, 8 entstehen (Fig. 1 a). Zum Vereinzeln und Verschließen des gefüllten Hohlkörpers 9 braucht die Schweißvorrichtung nur auf die Röhrchen 20 angesetzt zu werden, wodurch sich eine erhebliche Vereinfachung der Trennschweißung ergibt.ίο The neck and bottom pieces of the molded parts 3 point on the arcuate parts of the shaped recess weld separating edges 14 which form the hollow body 9 cut free in this area. The hollow bodies 9 are only attached to one another via tubes 20, which when the plastic tube 2 is inflated while it is traveling along the hollow domes 5, 6, 7, 8 arise (Fig. 1 a). To isolate and close the filled hollow body 9, the needs Welding device only to be placed on the tube 20, which results in a considerable Simplification of the separation weld results.
