    • An improved tire 200 having precured tire tread 10 for mounting to an unvulcanized or a vulcanized tire casing 100 is disclosed. The improved precured tread 10 has a pair of circumferentially continuous projections 60. One projection 60 extends axially outwardly from each of the lateral surfaces 40,50 of the tread. The rejection 60 provides a means for air tightly sealing the tread casing assembly at the lateral surfaces 40, 50 during the vulcanization of the tread 10 to the casing 100. The method of assembly includes placing the tread 10 and casing 100 in a smooth mold, closing the mold inflating a bladder expanding the casing 100 into the tread 10, the tread 10 correspondingly expands effecting an air tight sealing of the tread 10 and the mold at the annular projections 60 of the tread 10, applying heat and pressure causing a uniform flow of unvulcanized material radially outwardly along the tread edges. This invention provides uniform pressure distribution on the tire casing during curing. In this way belt package distortion is greatly minimized or eliminated. In another embodiment, a precured inner liner eliminates the need for an inflatable bladder.
    • 公开了一种改进的轮胎200,其具有用于安装到未硫化或硫化轮胎胎体100的预硫化轮胎胎面10。 改进的预硫化胎面10具有一对周向连续的突出部60.一个突出部60从胎面的每个侧表面40,50轴向向外延伸。 拒收60提供了一种用于在胎面10硫化到壳体100期间将胎面套管组件气密地密封在侧表面40,50处的装置。组装方法包括将胎面10和壳体100放置在光滑模具中, 关闭模具使将套管100膨胀到胎面10中的气囊膨胀,胎面10相应地膨胀,从而在胎面10的环形突起60处进行胎面10和模具的气密密封,施加热和压力,从而产生均匀的流动 的未硫化材料沿着胎面边缘径向向外。 本发明在固化期间在轮胎外壳上提供均匀的压力分布。 以这种方式,皮带包变形被大大减少或消除。 在另一个实施例中,预固化内衬消除了对可充气囊的需要。
