摘要: Die Erfindung bezieht sich auf ein Vulkanisierverfahren für Fahrzeugluftreifen, deren Reifenwülste (3) in montierter Stellung am radial inneren Umfang einer Felge neben sich im wesentlichen nach radial innen erstreckenden -Felgenhörnern angeordnet sind. Um Reifen hoher Haltbarkeit und mit gut dichtenden Reifenwülsten zu erhalten, wird vorgeschlagen, daß die Reifen im wesentlichen konturgerecht vulkanisiert werden, daß zum Abheizen der im Reifeninnenraum liegenden Dichtflächen für ein luftdichtes Anliegen des Reifens an der Felge zwei radial geteilte, im Durchmesser veränderbare und axial verschiebbare Wulstformringe (6) im eingefahrenen Zustand in den Innenraum des Reifenrohlings eingebracht werden, wobei mindestens einer der beiden Reifenwülste (3) oval verformt wird, daß die Formnngsegmente anschließend auf einen radialen Ringdurchmesser ausgefahren werden, mit dem die Formringe (6) mit ihren Formflächenteilen ohne Verformung der Wülste des Rohlings axial nach außen über diese hinweggeschoben werden, daß die Formringe anschließend wieder auf ihren kleinsten Durchmesser zusammengefahren und danach verriegelt werden und daß schließlich der Reifen in der Vulkanisierform vulkanisiert wird.

摘要: Along a building line (10), a green tyre (2) is built on a rigid toroidal support (11) having an outer surface (Ha) substantially conforming in shape to an inner surface (2a) of the green tyre (2). The green tyre (2) is then transferred to a bead moulding and prevulcanisation station (20) where each bead (6) of the tyre (2) is moulded by tightening it between a surface portion (23) of the toroidal support (11) and an annular clamping surface (22) carried by a removable tightening flange (27). The tightened beads (6) are prevulcanised through heat supply by means of electric resistors integrated into the tightening flanges (27). The tyre (2) with the prevulcanised and tightened beads (6) is transferred into a moulding cavity (44) having an inner wall of a shape substantially conforming to that of the outer surface (2b) of the moulded tyre, to carry out moulding of the tyre (2) and complete vulcanisation of same.

摘要: A tire curing press and method are characterized by a center mechanism (48) operative first to center the top bead of a green tire carcass with respect to the top mold section (42) and then the bottom bead with respect to the bottom mold section (44), and to hold the beads centered and axially separated as the press closes to cause the beads to register and seat with the toe rings of the top and bottom mold section simultaneously as the press closely approaches its closed condition. The center mechanism comprises top and bottom segmented annular clamping rings (52) adapted to engage and shape the axial interior of the bead area of the tire and respective chuck assemblies including a multi-faceted linear cam (102) and respective followers (64,66) for each ring segment (54, 56) operative to collapse each alternate ring segment (54) and then each other ring segment (56). The clamping rings achieve automatic loading, centering and unloading and may be used individually or paired in bladder or bladderless curing.
