Description
Die vorliegende Erfindung betrifft eine Weiterbildung der im Hauptpatent beschriebenen Ausführung und besteht darin, daß der elektrisch leitfähige Belag auf dem Preßschlauch durch eine elektrisch leitfähige Füllung des Preßschlauchinnern, z. B. eine elektrisch leitfähige Flüssigkeitsfüllung, gebildet wird. Man kann diese Ausführung so auffassen, als ob ein auf der Innenwand des Preschlauches angebrachter, elektrisch leitfähiger Belag das ganze Schlauchinnere ausfüllt. Der Belag braucht dann auf der Schlauchwandung nicht zu haften, und es können Schläuche der bisher üblichen Art und Herstellungsweise verwendet werden, die erst durch die besondere Art ihrer Füllung ihre Eignung für den Sonderzweck als Elektrode erhalten. The present invention relates to a further development of the main patent described embodiment and consists in that the electrically conductive coating on the press hose through an electrically conductive filling of the press hose interior, z. B. an electrically conductive liquid filling is formed. You can do this Conceive of the design as if a, electrically conductive coating fills the entire interior of the hose. The topping needs then not to adhere to the hose wall, and hoses can be the hitherto customary type and method of manufacture are used, which only through the special Type of their filling their suitability for the special purpose as an electrode.
Als elektrisch leitfähige Füllung kann z. B. Wasser verwendet werden, das durch Beifügung von Salzen oder Säuren für elektrischen Strom leitfähig gemacht wurde, z. B. kapn eine Wasserfüllung mit einem Zusatz von 2 So Ammoniumchlorid Verwendung finden.As an electrically conductive filling, for. B. water can be used, made conductive for electric current by adding salts or acids was e.g. B. kapn a water filling with an addition of 2 so ammonium chloride use Find.
Die Zuführung der elektrischen Energie kann über die in den Schläuchen üblicherweise vorhandenen Steckventile erfolgen, wobei aber dafür Sorge getragen werden muß, daß diesellben gegenüber der anderen Elektrode isoliert sind, oder durch besondere in die Schlauchwandung einvulkanisierte Anschlußstücke aus Metall oder elektrisch leitfähiger Kautschukmischung. The supply of electrical energy can be via the tubes usually existing plug-in valves take place, but care is taken must be that diesellben are isolated from the other electrode, or by special connection pieces made of metal or vulcanized into the hose wall electrically conductive rubber mixture.
In der Zeichnung ist ein Ouerschnitt durch eine Reifenform als ein Ausführungsbeispiel der Erfindung dargestellt. In the drawing, a cross section through a tire shape is shown as a Embodiment of the invention shown.
Anlehnend an die Bezeichnungsweise des Hauptpatentes ist der einer Wärmebehandlung zu unterwerfende Reifenrohling mit 1 bezeichnet, ein Formteil aus elektrisch isolierendem, z. B. keramischem Werkstoff mit 3 und ein übriger metallischer Formteil mit 4, während der in das Reifeninnere eingelegte Preß- oder Heizschlauch die Bezeichnung 5 erhalten hat. Das Innere dieses Schlauches ist ganz mit einer elektrisch leitfähigen Flüssigkeit 7 augefüllt, die durch das Steckventil 8 eingeführt ist. One is based on the designation of the main patent Heat treatment to be subjected to green tire denoted by 1, a molded part electrically insulating, e.g. B. ceramic material with 3 and the rest of the metallic Molded part with 4, while the compressed or heated hose inserted into the tire interior has received the designation 5. The inside of this tube is all with one electrically conductive liquid 7, which is introduced through the plug-in valve 8 is.
I)ie Anwendung des hier beschriebenen Erfindungsgedankens ist nicht auf Reifen beschränkt, sondern kann bei der Herstellung aller Kautschukgegenstände mit Hohlraumbildungen, z. z. 13. Schläuchen, Anwendung finden. An Stelle eines vollwandigen Preßschlauches kann auch eines der bekannten Ersatzgebilde verwendet werden, welches eine Abdichtung zwischen den Reifenwulsten bewirkt. In diesem Fall berührt die leitende Flüssigkeitsfüllung unmittelbar die Reifenwand, und es braucht nicht eine Heizschlauchwand miterwärmt zu werden. Die erfindungsgemäß ausgel>ildete Innenelektrode arheitel mit einer Außenelektrode, wie im Hauptpatent beschrieben, zusammen. I) he application of the inventive concept described here is not limited to tires but can be used in the manufacture of all rubber articles with cavities, e.g. z. 13. Hoses, find application. Instead of a full-walled Press hose can also be used one of the known replacement structures, which causes a seal between the tire beads. In this case, the senior touches Liquid filling directly the tire wall, and it does not need a heated hose wall to be warmed up. The inner electrode designed according to the invention arheitel with an outer electrode, as described in the main patent, together.
P A T E N T A N S P R Ü C H Form zur Wärmebehandlung von Kautschuk oder kautschukähnlichen Stoffen im elektrischen, hochfrequenten Kondensatorfeld nach Patent 831 860 für Reifen oder ähnliche Gegenstände mit Hohlraumbildung, wobei eine der Elektroden von einem elektrisch leitenden Aufstrich oder Belag auf dem im Innern des Reifens befindlichen Preßschlauch (Heizschlauch) gebildet wird, dadurch gekennzeichnet, daß der elektrisch leitfähige Belag auf dem Preßschlauch (5) durch eine elektrisch -leitfähige Füllung des Preßschlauchinnern, z. 1'. eine elektrisch leitfähige Flüssigkeitsfüllung (7), gebildet wird.
