Description

Dorn für die Herstellung von Gummischläuchen. Es war bislang nicht möglich, Gummischläuche derjenigen Art, bei welcher um die Gummischlauchseele Stoffe und Gummilagen in mehrfacher bzw. abwechselnder Reihenfolge gelegt werden, in beliebigen Längen einwandsfrei herzustellen. Der Grund liegt in der ungeeigneten Beschaffenheit des Dornes. Letzterer bestand entweder aus Metall oder aus Gummi.Mandrel for the production of rubber hoses. It wasn't before possible, rubber hoses of the type in which substances around the rubber hose core and rubber layers are laid in multiple or alternating order, in any order Produce lengths flawlessly. The reason lies in the unsuitable nature of the thorn. The latter was either made of metal or rubber.

Der aus Metall hergestellte Dorn verlangte einen Vulkanisierkessel von unnatürlich großer Länge. Auch war es nicht möglich, den Schlauch bei größeren Längen des Dornes unbeschädigt von letzterem herunterzubringen.The metal-made mandrel required a vulcanizing kettle of unnaturally great length. It was also not possible to use the hose with larger ones To bring down lengths of the mandrel undamaged from the latter.

Bestand der Dorn aus weichem Material, z. B. Gummi, so wurde bei der Herstellung des hlöppelmantels die Gummischlauchseele zu fest auf den Gummidorn gedrückt, und es machte große Schwierigkeiten, den Gummidorn aus dem fertigen Schlauch zu entfernen.If the mandrel was made of soft material, e.g. B. rubber, so was the Production of the hlöppelmantels the rubber hose core too tightly on the rubber mandrel pressed, and it made great difficulty removing the rubber mandrel from the finished hose to remove.

Diesen Übelständen wird gemäß der Erfindung dadurch begegnet, daß die Gummischlauchseele mit einer leicht erstarrenden Masse, wie z. B. Gelatine, ausgefüllt wird, so daß diese Masse nach ihrem Erstarren die bislang üblichen, obenerwähnten Dorne ersetzt. Hierdurch wird es erst möglich, die Umklöpplung der Schlauchseele in unbegrenzten Längen durchzuführen, ohne daß durch das bislang während des Arbeitsverfahrens erforderlich gewesene Verschieben oder jeweilige Entfernen des Dornes die Schlauchseele leidet oder sich in ihrer Form verändert, so daß jetzt eine Umspritzung und weiteres Umklöppeln unbehindert in beliebiger Anzahl und Reihenfolge und ununterbrochenem Arbeitsgang erfolgen kann.These drawbacks are countered according to the invention in that the rubber tube core with a slightly solidifying mass, such as. B. gelatin, is filled, so that this mass, after its solidification, the previously usual, above-mentioned Replaced mandrels. This only makes it possible to clap the hose core to be carried out in unlimited lengths without being affected by this so far during the working process Any shifting or removal of the mandrel that has been necessary, the hose core suffers or changes in shape, so that now an encapsulation and more Unhindered winding in any number and order and uninterrupted Operation can be done.

Nachdem auf diese Weise der Schlauch hergestellt ist, wird der Dorn durch chemische oder physikalische Behandlung seiner :Masse so verändert, daß er durch einfaches Auslaufenlassen entfernt werden kann. Der Schlauch wird dann in eine Form gebracht und in bekannter Weise beispielsweise wie bei den Hohlkörpern durch Innendruck gegen eine beheizte Formwand gepreßt und so vulkanisiert.After the hose is made in this way, the mandrel is made by chemical or physical treatment of his: mass so that he can be removed by simply draining it. The hose is then in brought a shape and in a known manner, for example as with the hollow bodies pressed against a heated mold wall by internal pressure and thus vulcanized.
