Description
Auf der Trommelachse der Konfektioniertrommel ist gemäß Erfindung ein axial verschiebbarer ringförmiger Kolben 1 mit einer konischen Auflaufseite angeordnet, der in einen analog konischen ausgearbeiteten Spreizring 2 mit bekannten Mitteln drückbar ist und mittels Federn 6 zurückholbar gestaltet ist. Der Spreizring 2 besteht aus einem festen federnden und verschleißfesten Material wie z. B. Teflon, Miramid oder einem anderen Kunststoff mit elastischen Eigenschaften. Wechselseitig vom inneren und äußeren Durchmesser ausgehend weist der Spreizring 2 Schlitze auf, die in axialen Durchgangslöchern 8 enden. Der Durchmesser der Durchgangslöcher 8 beträgt etwa ein Drittel bis der Hälfte der Breite der sich ergebenden Segmente des Spreizringes 2, und diese ragen 1,5 bis 4,0mm an den jeweiligen inneren bzw. äußeren Durchmesser des Spreizringes 2 heran.On the drum axis of the confectioning drum according to the invention, an axially displaceable annular piston 1 is arranged with a conical bearing side, which can be pressed in an analog conical elaborated spreader ring 2 by known means and designed by means of springs 6 retrievable. The spreader 2 consists of a solid resilient and wear-resistant material such. As Teflon, Miramid or another plastic with elastic properties. Starting from the inner and outer diameters, the spreader ring 2 has slots which terminate in axial through-holes 8. The diameter of the through holes 8 is about one-third to one-half the width of the resulting segments of the spreader ring 2, and these protrude 1.5 to 4.0 mm to the respective inner and outer diameter of the spreader ring 2 zoom.
Der Spreizring 2 ist weiterhin mit einem Gummiring 3 mit einer Shorehärte von 65-75° in einer Dicke von 20-30mm überdeckt.The spreader ring 2 is further covered with a rubber ring 3 with a Shore hardness of 65-75 ° in a thickness of 20-30mm.
Oberhalb dieses Gummiringes 3 befindet sich der Hochschlagbalg 5, auf dem gemäß diesem Ausführungsbeispiel die Konfektionierung eines Fahrzeugluftreifens erfolgt.Above this rubber ring 3 is the high-lift bellows 5, on which takes place according to this embodiment, the assembly of a pneumatic vehicle tire.
Die Funktion der Konfektioniertrommel wird wie folgt beschrieben.The function of the confectioning drum is described as follows.
Nach dem Auflegen einzelner Aufbauelemente auf die Konfektioniertrommel, z. B. Karkaßlagen, wird das zentrisch festzuklemmende Aufbauelement, z.B. die mit Kerngummi versehene Wulst, mit bekannten Elementen darübergebracht. Der ringförmige Kolben 1 wird in den Spreizring 2 gedrückt, wobei dieser sich aufgrund seiner Elastizität im Durchmesser vergrößert und das festzuklemmende Aufbauelement exakt zentrisch spannt. Durch den Gummiring 3 wird das Fixieren des Aufbauelementes begünstigt, da sich dieses leicht in den Gummiring 3 eindrücken kann.After placing individual components on the confectioning drum, z. B. carcass plies, the centrally clamped structural element, e.g. the beaded rubber bead, with known elements over it. The annular piston 1 is pressed into the spreader ring 2, wherein it increases in diameter due to its elasticity and clamps the clamping element firmly centered exactly. By the rubber ring 3, the fixing of the structural element is favored, since this can easily be pressed into the rubber ring 3.
Die erfindungsgemäße Einrichtung besteht im wesentlichen pro Trommelseite nur aus drei Elementen, die aus verschleißfestem Material herstellbar sind. Der Aufbau ist dadurch einfach und wartungsarm.The device according to the invention consists essentially per drum side only of three elements that can be produced from wear-resistant material. The structure is thus simple and low maintenance.
Das absolut zentrische Spannen der aufzubringenden Elemente wird durch die Erfindung gesichert, so daß sich qualitativ hochwertige Fahrzeugluftreifen herstellen lassen, die sich insbesondere durch eine hervorragende Gleichförmigkeit auszeichnen.The absolutely centric clamping of the applied elements is ensured by the invention, so that it is possible to produce high-quality pneumatic vehicle tires, which are characterized in particular by an excellent uniformity.
