    摘要： A wheel shaping apparatus including a single cotter for expanding first and second dies circumferentially split into a plurality of first and second die elements, respectively. The single cotter is supported by a cotter supporting member at one end portion of the cotter and is also supported by a cotter guide at the other end portion of the cotter during shaping of a rim element. Because of the single cotter supported at both end portions thereof, rim bead seat portions located at axially end portions of the rim element are shaped in an accurate alignment with each other and almost exactly parallel to each other. In the case when ring-like members are provided around the first and second dies or when teeth are formed at sides of each first and second die element, formation of local deformations at gaps between two adjacent first die elements and between two adjacent second die elements is suppressed.

    摘要翻译： 一种轮胎成形设备，包括用于分别将第一和第二模具沿周向分割成多个第一和第二模具元件的单个开口。 单个开口由开口的一个端部处的开口支撑构件支撑，并且在边缘元件成形期间还在开口的另一端部处由开口导向器支撑。 由于在其两端部支撑单个开口，所以位于轮辋元件的轴向端部的轮辋凸缘座部分成形为彼此精确对准并且几乎完全相互平行。 在环形构件设置在第一和第二模具周围或者当在每个第一和第二模具元件的侧面处形成齿时，在两个相邻的第一模具元件之间的间隙处和在两个相邻的第二模具元件之间形成局部变形 被压制

    摘要： A delivering apparatus for selectively delivering a work conveyed from one inlet path to one of three paths. The delivering apparatus is disposed at an intersection of the inlet path and the exit paths. The delivering apparatus comprises a series of free rollers, a first stopper, and a series of chains. The series of free rollers can take upper and lower positions in a vertical direction between which an uppermost portion of the series of chains is positioned. When the series of free rollers takes the upper position and the first stopper is opened, the work is selectively conveyed out onto a first exit path which is located opposite to the inlet path. When the series of free rollers takes the lower position, however, the work is selectively conveyed out onto either a second exit path or a third exit path according to the rotational direction of the series of chains.

    摘要翻译： 一种递送装置，用于选择性地将从一个入口路径输送的工件传送到三个路径之一。 输送装置设置在入口路径和出口路径的交叉点处。 输送装置包括一系列自由辊，第一止动件和一系列链条。 一系列自由辊可以在垂直方向上上下位置，在该方向上，一系列链的最上部分被定位。 当一系列自由辊处于上部位置并且第一止动件打开时，工件被选择性地输送到与入口路径相对的第一出口路径上。 然而，当一系列自由辊处于较低位置时，根据一系列链条的旋转方向，将工件选择性地输送到第二出口路径或第三出口路径上。
