Description
Die Erfindung betrifft nun ein besonderes Verfahren zum Vulkanisieren von Kautschukschläuchen, die in bekannter Weise bleiummantelt und mit einer Gewebeeinlage versehen sind. Die in dieser Weise hergestellten Schläuche wurden bisher auf Trommeln aufgewickelt, mit Preßluft oder Flüssigkeit gefüllt und dann in den Vulkanisierkessel eingebracht. Dieses Verfahren hat mancherlei Nachteile. Der Schlauch wird durch seine Aufwicklung .auf die Trommel in gekrümmtem Zustand vulkanisiert, weshalb der Schlauch in fertigem Zustand immer das Bestreben hat, diese Krümmung beizubehalten.The invention now relates to a particular method of vulcanizing of rubber hoses, which are lead-coated in a known manner and with a fabric insert are provided. The hoses produced in this way were previously on drums wound up, filled with compressed air or liquid and then in the vulcanizing kettle brought in. This method has several disadvantages. The hose is through its winding. on the drum in a curved state vulcanized, which is why the Hose in its finished state always strives to maintain this curvature.
Weiter ist dieses bekannte Verfahren mit dem Nachteil verknüpft, daß bei Vulkanisation mit Dampf der Dampfverbrauch wegen des großen Dampfraumes sehr hoch ist. Wegen dieses Umstandes wird das Verhältnis des Schlauchvolumens sehr ungünstig, und es müssen zunächst große Massen angeheizt werden, bevor Wärme für die Vulkanisation frei wird.This known method is also associated with the disadvantage that in the case of vulcanization with steam, the steam consumption is very high because of the large steam space is high. Because of this fact, the ratio of the hose volume is very unfavorable, and large masses must first be heated before the vulcanization is heated becomes free.
Erfindungsgemäß wird vorgeschlagen, die bleiummantelten,unter Flüssigkeits- oder Luftdruck stehenden Kautschukschläuche in gestrecktem Zustand und mit freiem Spiel durch einen Heizraum hindurchzüführen. Damit sind die -geschilderten Mängel, welche das bisherige Verfahren bezüglich des Dampfverbrauches und auch bezüglich der Güte des späteren Schlauches hat, in einfacher Weise vermieden.According to the invention it is proposed that the lead-coated, under liquid or air pressure rubber hoses in the stretched state and with free Guide the game through a boiler room. This means that the deficiencies described are which the previous method in terms of steam consumption and also in terms of the quality of the later hose, avoided in a simple manner.
In der Zeichnung ist eine Einrichtung zur -Durchführung des Verfahrens schematisch in den Abb. i und 2 dargestellt, wobei die Abb. 2 in vergrößertem Maßstab einen Querschnitt durch die in Abb. i dargestellte Heizkammer zeigt.In the drawing is a device for performing the process shown schematically in Figs. i and 2, Fig. 2 on an enlarged scale shows a cross-section through the heating chamber shown in Fig. i.
Die Bleimantelpresse ist mit i und der zu ummantelnde Schlauch mit 2 bezeichnet. Mit 3 ist der in der Presse i mit einem Bleimantel umgebene Schlauch bezeichnet. Der Schlauch wird von der Trommel q. abgewickelt und im ummantelten Zustand auf die Trommel 5 aufgewickelt. Mit 6 ist eine rohrförmige Heizkammer bezeichnet, durch die hindurch das obere Trum eines endlosen Förderers 7 hindurchgeführt ist. Die Heizkammer ist an beiden Seiten offen, so daß der bleiummantelte Schlauch 3 beim Abwickeln von der Tromme15 frei in die Heizkammer ein-und wieder ausgeführt werden kann. Das Heizmittel befindet sich in der Doppelwand des Heizrohres 6, so daß im Innern die strahlende Wärme zur Auswirkung auf den mit Hilfe .des Förderers 7 durch den Heizraum hindurchgeführten und mit Blei ummantelten Schlauch zur Auswirkung kommt. Der Schlauch 3 steht hierbei in üblicher Weise unter einem Flüssigkeits- oder Luftdruck.The lead jacketed press is marked with i and the hose to be jacketed is marked with 2 designated. With 3 is the hose surrounded by a lead jacket in the press i designated. The hose is taken from the drum q. unwound and sheathed Wound on the drum 5 state. With a tubular heating chamber is designated, through which the upper run of an endless conveyor 7 is passed. The heating chamber is open on both sides so that the lead-sheathed hose 3 when unwinding from the drum15 freely in and out of the heating chamber can be. The heating means is located in the double wall of the heating tube 6, see above that inside the radiating heat to the effect on the with the help of the conveyor 7 through the boiler room and sheathed lead sheathed hose to the effect comes. The hose 3 is here in the usual way under a liquid or air pressure.
