Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Fahrzeugluftreifens mit einem eine Laufstreifencap und eine Laufstreifenbase aufweisenden Laufstreifen, wobei die Laufstreifenbase aus einer elektrisch leitfähigen Kautschukmischung und die Laufstreifencap durch Spulen zumindest eines Materialstreifens aus einer elektrisch nicht leitfähigen, insbesondere Kieselsäure enthaltenden Kautschukmischung hergestellt werden.The invention relates to a method for producing a pneumatic vehicle tire with a tread cap and a tread base having tread, wherein the tread base made of an electrically conductive rubber compound and the tread cap are produced by coils of at least one strip of material of an electrically non-conductive, especially silica-containing rubber mixture.
Es ist bekannt, dass Kieselsäure enthaltende Laufstreifen, die den Fahrzeugreifen an sich gute Fahreigenschaften, wie einen geringen Rollwiderstand und gute Nassrutscheigenschaften verleihen, elektrisch kaum leitfähig sind, sodass elektrostatische Aufladungen unangenehme Entladungsvorgänge verursachen können. Es ist daher üblich, bei solchen Fahrzeugluftreifen im Laufstreifen durch elektrisch leitfähigen Gummi Passagen zu schaffen, die eine elektrisch leitfähige Verbindung der Außenfläche des Laufstreifens zum Unterbau herstellen.It is known that silica-containing treads which impart to the vehicle tire per se good drivability, such as low rolling resistance and good wet-skid properties, are electrically hardly conductive, so that electrostatic charges can cause uncomfortable discharging operations. It is therefore common practice to provide passages in such tread tires by electrically conductive rubber which provide an electrically conductive connection of the outer surface of the tread to the base.

Bei den beiden zuletzt genannten Verfahren erfolgt daher ein Einfügen elektrisch leitfähiger Teile in den Laufstreifen bzw. in die Laufstreifencap und die Laufstreifenbase während der Extrusion. Diese bekannten Verfahren lassen sich bei Laufstreifen, die durch Spulen eines Materialstreifens aus einer Kautschukmischung hergestellt werden, nicht anwenden.In the two latter methods, therefore, an insertion of electrically conductive parts in the tread or in the tread cap and the tread base during the extrusion takes place. These known methods can not be applied to treads made by winding a strip of material from a rubber compound.
Der Erfindung liegt daher die Aufgabe zu Grunde, auf einfache Weise in einer durch Spulen eines Materialstreifens hergestellten Laufstreifencap aus einer elektrisch nicht leitfähigen Kautschukmischung lokal einen in Umfangsrichtung umlaufenden Einsatz aus einer elektrisch leitfähigen Kautschukmischung einbringen zu können.The invention is therefore based on the object to be able to bring in a simple way in a produced by coils of a strip of material tread cap of an electrically non-conductive rubber mixture locally a circumferentially encircling insert of an electrically conductive rubber mixture.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Laufstreifen auf einer expandierbaren, segmentierten Hilfstrommel aufgebaut wird, deren Segmentteile in axialer Richtung geteilt und bewegbar sind, wobei bei auseinander gefahrenen Segmentteilen die Laufstreifenbase aufgebracht wird, die Segmentteile unter Bildung einer örtlichen Wölbung zusammengefahren werden, die Laufstreifencap beidseitig der Wölbung gespult wird und der fertige Laufstreifen der Hilfstrommel entnommen wird.This object is achieved in accordance with the invention in that the tread is constructed on an expandable, segmented auxiliary drum whose segment parts are divided and movable in the axial direction, the tread base being applied when the segment parts are driven apart, the segment parts are brought together to form a local curvature, The tread cap is wound on both sides of the curvature and the finished tread of the auxiliary drum is removed.
Der Fahrzeugluftreifen gemäß der Erfindung ist besonders einfach aufgebaut, da die Laufstreifenbase das elektrisch leitfähige Gummimaterial für den rippenartigen Einsatz zur Verfügung stellt. Die Herstellung erfordert kein gesondertes Hantieren mit einer leitfähigen Kautschukmischung zum Bilden einer umlaufenden elektrisch leitfähigen Gummirippe im Laufstreifen und keine komplizierten Verfahrensschritte. Von besonderem Vorteil bei der Erfindung ist, dass das Spulen der Laufstreifencap durch das Bilden der Rippe nicht beeinträchtigt und nicht behindert wird.The pneumatic vehicle tire according to the invention is particularly simple in construction, since the tread base provides the electrically conductive rubber material for the rib-like insert. The manufacture does not require separate handling with a conductive rubber compound to form a circumferential electrically conductive rubber fin in the tread and no complicated process steps. Of particular advantage in the invention is that the coils of the tread cap is not affected by the formation of the rib and is not hindered.
Die Ausformung bzw. die Ausformungen der Laufstreifenbase werden während der Herstellung des Laufstreifens, und zwar vor dem Spulen der Laufstreifencap, aus der Laufstreifenbase gebildet.The shape or the formations of the tread base become during the production of the tread, prior to winding the tread cap, formed from the tread base.
Dabei wird bei der Herstellung des Laufstreifens in den in Umfangsrichtung umlaufenden Spalt zwischen den auseinander gefahrenen Segmentteilen der Segmente der Hilfstrommel vor dem Aufbringen der Laufstreifenbase eine in ihrem äußeren Durchmesser vergrößerbare Einrichtung eingebracht. Gemäß einer bevorzugten Ausführung der Erfindung ist diese Einrichtung ein aufblasbarer Balg. Mit einem Balg lässt sich auf einfache Weise eine umlaufende Wölbung in der Laufstreifenbase erzeugen.In this case, in the production of the tread in the circumferentially circumferential gap between the divergent segment parts of the segments of the auxiliary drum before the application of the tread base is introduced an enlargeable in its outer diameter means. According to a preferred embodiment of the invention, this device is an inflatable bellows. With a bellows can be easily create a circumferential curvature in the tread base.
Bei einer anderen Ausführungsvariante der Erfindung ist die Einrichtung ein fester, in Umfangsrichtung segmentierter Ring aus Metall oder Kunststoff. Auch mit einem solchen Ring lässt sich eine in Umfangsrichtung umlaufende Wölbung, die dann später die Rippe im Laufstreifen bildet, erzeugen. Wird die Außenseite des Ringes bzw. seiner Segmente mit einer Reihe von Erhebungen oder Vorsprüngen versehen, so wird die rohe Laufstreifenbase beim Vergrößern des Durchmessers des Ringes lokal ausgewölbt, sodass im fertigen Reifen diskrete, örtlich begrenzte Passagen leitfähigen Gummis vorhanden sind, die in Umfangsrichtung in einer Reihe angeordnet sind.In another embodiment of the invention, the device is a solid, segmented in the circumferential direction ring made of metal or plastic. Even with such a ring can be a circumferential circumferential curvature, which then later forms the rib in the tread, produce. If the outer side of the ring or its segments is provided with a series of projections or protrusions, the raw tread base is locally bulged as the diameter of the ring increases to provide discrete, localized passages of conductive rubber circumferentially in the finished tire are arranged in a row.
Die Laufstreifencap kann beidseitig der Wölbung in einer oder in zwei Lagen gespult werden. Dabei kann vorgesehen sein, der Wölbung der Laufstreifenbase unmittelbar benachbart etwas weniger Material aufzubringen. Damit kann beim nachfolgenden Zusammenfahren der Segmente der Hilfstrommel verhindert werden, dass sich zuviel Material der Laufstreifencap seitlich der gebildeten Rippe bzw. der Ausformungen befindet.The tread cap can be wound on both sides of the buckle in one or two layers. It can be provided to apply the curvature of the tread base immediately adjacent slightly less material. This can be prevented during subsequent collapse of the segments of the auxiliary drum, that too much material of the tread cap is located laterally of the formed rib or the formations.
