Die Erfindung betrifft eine Reifenaufbaumaschine zum Flachaufbau und anschließenden Bombieren von Karkassen mit zwei gleichachsig zueinander ausgerichteten und gegeneinander verschiebbaren Wulsthaltescheiben, die radial spreizbar sind, insbesondere mit Wulsthaltevorrichtungen, die aus je einem aufblasbaren Schlauch und einem diesen abdeckenden, ausdehnbaren Gummiring mit Mantelrille bestehen, und zwischen denen ein Ringraum an eine Druckluftquelle zum Verformen der Karkasse anschließbar ist, sowie mit den Wulsthaltescheiben zugeordneten Vorrichtungen zum Umschlagen und Anrollen der Ränder der Gewebelagen der Karkasse über die auf der Gewebelage an den Wulsthaltescheiben angelegten Wulstringe.The invention relates to a tire building machine for flat building and subsequent crowning of carcasses with two coaxially aligned and mutually displaceable bead retaining disks, which are radially expandable, in particular with bead holding devices, each consisting of an inflatable Hose and an expandable rubber ring with a jacket groove covering it, and between which an annular space can be connected to a compressed air source for deforming the carcass, as well as with the bead retaining disks associated devices for turning over and rolling the Edges of the fabric layers of the carcass over those placed on the fabric layer on the bead retaining washers Bead rings.
Bei den bekannten Aufbautrommeln ist der Ringraum zwischen den Wulsthaltescheiben luftdicht von einem Mantel überspannt. Der aufblähbare Mantel kann sich auch rechts und links seitlich der Wulsthaltescheiben erstrecken. Auf dem Mantel werden die Karkassenlagen aufgewickelt, die Wulstringe aufgesetzt und Umfangsteile der Wulsthaltescheiben gegen die Wulstringe angepreßt, so daß der Mantel mit eingeklemmt wird. Anschließend erfolgt das Bombieren. Der Erfindung liegt die Aufgabe zugründe, den aufblähbaren Mantel für den Bombiervorgang entbehrlich zu machen.In the known building drums, the annular space between the bead retaining washers is airtight spanned over a coat. The inflatable jacket can also be on the right and left side of the bead retaining washers extend. The carcass plies are wound onto the casing and the bead rings are attached and peripheral portions of the bead retaining washers are pressed against the bead rings so that the shell is pinched with. Then the crowning takes place. The invention is based on the task to make the inflatable jacket unnecessary for the crowning process.
Die Erfindung besteht darin, daß der zwischen den Wulsthaltescheiben liegende Ringraum am äußeren Umfang offen und durch die aufzulegende Gewebelage der Karkasse schließbar ist. Es hat sich gezeigt, daß die Karkassenlagen so dicht sind, daß sie ohne Verwendung eines Mantels den Luftdruck beim Aufblähen halten. Durch die Erfindung wird der Mantel eingespart und der Vorteil erzielt, daß die Karkassenlagen einwandfreier in die Reifengestalt übergehen, weil sie nicht an der Oberfläche eines Mantels haften. Dabei kann das Umschlagen der Karkassenlagenenden auf den Mittelteil der Karkasse in gleicher Weise erfolgen, wie bei der bekannten Aufbautrommel, da der Mittelteil der Karkasse durch Beaufschlagen mit einem entsprechenden Druck die benötigte Abstützung beim Anlegen bietet.The invention consists in that the annular space lying between the bead retaining washers on outer periphery is open and can be closed by the fabric layer to be placed on the carcass. It has shown that the carcass plies are so dense that they can withstand the air pressure without the use of a jacket Keep puffing up. The invention saves the jacket and has the advantage that the Carcass layers blend into the tire shape more perfectly because they are not on the surface of a tire Stick coat. The carcass ply ends can be turned over to the middle part of the carcass take place in the same way as in the known building drum, since the middle part of the carcass through Applying an appropriate pressure provides the necessary support when applying.
Vorteilhafterweise sind an den einander abgekehrten Seiten der Wulsthaltescheiben eine Mehrzahl von sich zu einem Spreizzylinder ergänzenden Segmenten mit je einem auf dem Umfang angeordneten auftreibbaren Ringschlauch und wenigstens je einem im Inneren angeordneten Ringschlauch schwenkbar gelagert. Hierdurch wird die Art der Abstützung dem Ablauf des "Anrollvorganges der Karkassenenden an den Mittelteil der Karkasse besser angepaßt.Advantageously, there are a plurality of the bead retaining disks on the sides facing away from one another of complementary segments to form a spreader cylinder, each with one arranged on the circumference expandable ring tube and at least one ring tube arranged inside each pivotable stored. As a result, the type of support is adapted to the sequence of the "rolling on of the carcass ends" the middle part of the carcass better adapted.
