KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf eine Vorrichtung zum Vulkanisieren von Laufmänteln für Luftradreifen. Es ist bekannt, zum Vulkanisieren zweiteilige Formen mit Gewebeeinlage zu benutzen, welchen ein Heizmittel so zugeführt wird, daß es die Gewebeeinlage durchdringen und auf den zu vulkanisierenden Mantel einwirken kann. Bisher wurde bei solchen Formen die Gewebeeinlage, für sich umThe invention relates to a device for vulcanizing barrel casings for pneumatic tires. It is known to vulcanize two-part molds with a fabric insert to use, which a heating means is supplied so that it is the fabric insert can penetrate and act on the coat to be vulcanized. So far, such Reshape the fabric insert for yourself
ίο den Mantel gewunden, was den Nachteil hat, daß der Mantel, wenn er weich wird, oft nicht den nötigen Halt findet und daher verzogen aus der Form kommt. Dieser Übelstand wird gemäß der Erfindung dadurch vermieden, daß die Gewebeumhüllung in den beiden Formhälften selbst befestigt und unterstützt ist, so daß sie genau die richtige Lage einnimmt und ohne Auf- und Abwickeln mit den Formhälften abgenommen und wieder aufgesetzt werden kann.ίο the coat twisted, which has the disadvantage that the coat, when it becomes soft, often does not find the necessary hold and is therefore warped comes out of shape. This drawback is avoided according to the invention in that the tissue wrapping is fastened and supported in the two mold halves themselves, so that it takes exactly the right position and without winding and unwinding with the mold halves can be removed and put back on.
Der Erfindungsgegenstand ist auf der Zeichnung im Schnitt dargestellt. Die Form ist mit einem ringförmigen Kern 1 versehen, dessen Außenfläche der Innenfläche des fertigen Mantels entspricht. Der Kern 1 ist mit einem Flansch 2 ausgebildet, durch' welchen die ■ beiden Formhälften in richtigem Abstande voneinander gehalten werden, wenn sie vor dem Vulkanisieren miteinander verbunden werden. Die beiden Formhälften 3 und 4 sind außen und innen mit Lappen 5 und 6 ausgebildet, durch welche Verbindungsbolzen greifen. Zur Heizung der Form dienen Dampfkammern 9, denen durch Bohrungen 10 Dampf zugeführt wird. Die der Lauffläche des Mantels gegenüberstehenden Dampfkammern 9 haben eine Anzahl von Rippen 27, zwischen denen Kanäle 26 ausgebildet sind, welche dem Dampf den Zutritt zu der. Gewebeeinlage 25 freilassen. Diese wird im Innern jeder Formhälfte um einen Ring 23 doppelt gelegt und durch Klemmringe 19 und Schrauben 21 festgehalten. Die freien Enden der Einlage treten aus der Form hervor und werden durch Klemmringe 18 auf Kegelflächen 17 der Formhälften festgehalten. Auf diese Art kann man der Einlage die nötige Spannung geben, während sie durch die Rippen 27 in der richtigen Lage gehalten wird.The subject of the invention is shown in section on the drawing. The shape is provided with an annular core 1, the outer surface of which is the inner surface of the finished Mantle corresponds. The core 1 is formed with a flange 2 through which the ■ two mold halves at the correct distance are held from each other if they are bonded together prior to vulcanization. The two mold halves 3 and 4 are designed with tabs 5 and 6 on the outside and inside, through which connecting bolts engage. Steam chambers are used to heat the mold 9, which 10 steam is supplied through holes. That of the tread of the mantle opposing steam chambers 9 have a number of ribs 27 between which channels 26 are formed, which the steam access to the. Fabric insert 25 set free. This is placed twice around a ring 23 inside each mold half and held in place by clamping rings 19 and screws 21. Kick the free ends of the insert out of the mold and are by clamping rings 18 on conical surfaces 17 of the mold halves held. In this way you can give the insert the necessary tension while it is held in the correct position by the ribs 27.
