  Zusammenklappbare   Aufbautrommel für den flachen Autbau   von   Fahrzeugradreifen.   



   Die Erfindung bezieht sieh auf zusammenklappbare Aufbautrommeln zur Herstellung von Fahrzeugradreifen und betrifft eine solche Ausführung, die für den flachen Aufbau namentlich solcher Reifen bestimmt ist, die bei verhältnismässig kleinem Wulstringdurchmesser eine grosse Breite in flachem Zustand haben. 



   Um bei diesen zusammenklappbaren   Aufbautrommeln   das Abnehmen der Reifen durch weitgehendes Einziehen der   Mantelteile   zu erleichtern, ist erfindungsgemäss das aus einem oder mehreren Teilen bestehende   Schlussstiick   des Trommelmantels parallel der Drehachse der Trommel verschiebbar und das gegebenenfalls auch mehrere Teile umfassende Hauptteil des Trommelmantels um eine senkrecht zu dieser   Trommelaehse   gerichtete und diese kreuzende Achse aus der Drehebene der Trommel ausschwenkbar. Diese Schwenkachse ist hiebei ausserhalb der senkrecht zur Drehachse der Trommel durch die Mitte der Trommel gelegten Ebene, zweckmässig nahe einem Trommelrand angeordnet, so dass das Ausschwenken nicht durch die Trommeldrehachse verhindert ist.

   Da die neue Einrichtung vornehmlich zum Aufbau solcher Fahrzeugradreifen bestimmt ist, deren Breite in flachem Zustand etwa 75% des Wulstringdurchmessers beträgt, ist das   Mantelsehlussstüek   entgegen Federwirkung kippbar, so dass das   Sehlussstüek   beim Ausschwenken des Hauptmantelteiles dem von den Wulsträndern beschriebenen Bogen folgen kann.

  Foldable building drum for the flat construction of vehicle wheel tires.



   The invention relates to collapsible building drums for the production of vehicle wheel tires and relates to such a design which is intended for the flat construction, namely tires which have a large width in a flat state with a relatively small bead ring diameter.



   In order to make it easier to remove the tires in these collapsible building drums by largely pulling in the casing parts, according to the invention the end piece of the drum casing consisting of one or more parts can be displaced parallel to the axis of rotation of the drum and the main part of the drum casing, which may also comprise several parts, can be displaced perpendicular to this Trommelaehse directed and this crossing axis can be swiveled out of the plane of rotation of the drum. This pivot axis is here outside the plane perpendicular to the axis of rotation of the drum through the center of the drum, expediently arranged near the edge of the drum, so that pivoting out is not prevented by the drum axis of rotation.

   Since the new device is primarily intended for the construction of such vehicle wheel tires, the width of which in the flat state is about 75% of the bead ring diameter, the cover end piece can be tilted against the action of a spring, so that the cover end piece can follow the curve described by the bead edges when the main cover part is pivoted out.
