摘要： A method of making radial pneumatic tires substantially reduces or eliminates sidewall indentations in the inflated tire. A plurality of cuts is made in one end of each layer of ply fabric where the end of the ply fabric overlaps the other end to form a splice which results in the generally annular shape of the ply layer. The cuts extend in a direction generally transverse to the end edge and preferably have a length which is approximately the same as the width of the overlap of the cut edge with the other edge. The cuts prevent overtensioning of the ply cords, which otherwise result in sidewall indentations.

摘要： A center split, segmented mold for curing a complete tire is provided, comprising a mold container top containing a top mold sidewall plate and a plurality of top tread segments disposed generally equidistant from a central axis and adjacently abutting each other when the mold is in a closed position; and a mold container bottom containing a bottom mold sidewall plate and a plurality of bottom tread segments disposed generally equidistant from the axis and adjacently abutting each other when the mold is in a closed position. Each of the top and bottom tread segments are resiliently biased toward the mold centerline by spring mechanisms, and are slidably coupled to respective frustoconical surfaces of the mold container, such that vertical movement of the mold container top along the axis from a closed position to an open position is translated into outward radial movement of the top and bottom tread segments away from the axis. The top and bottom tread segments mate when the mold is in the closed position in a plane which may be offset from the mold centerline. The top mold sidewall plate mates with the top tread segments and the bottom mold sidewall plate mates with the bottom tread segments at respective seating joints which limit inward radial movement of the top and bottom tread segments toward the axis. Pin assemblies for each tread segment limit outward radial movement of the tread segments away from the axis.
摘要翻译： 提供了一种用于固化整个轮胎的中心分割分段模具，包括：模具容器顶部，其包含顶模侧壁板和多个顶部踏面段，所述多个顶部胎面段大致与中心轴线等距设置，并且当模具处于 封闭位置 以及模具容器底部，其包含底部模具侧壁板和多个底部胎面部分，所述多个底部胎面部段在模具处于关闭位置时与所述轴线大致等距离并相互邻接。 顶部和底部胎面段中的每一个通过弹簧机构朝向模具中心线弹性偏压，并且可滑动地联接到模具容器的相应的截头圆锥形表面，使得模具容器顶部沿着轴线从关闭位置到 打开位置被转换成远离轴线的顶部和底部胎面段的向外径向运动。 当模具处于可能从模具中心线偏移的平面中的关闭位置时，顶部和底部胎面段配合。 顶部模具侧壁板与顶部胎面段配合，并且底部模具侧壁板与相应座椅接合处的底部胎面段配合，从而限制顶部和底部胎面段朝向轴线的向内径向移动。 每个胎面花纹片的销组件限制胎面花纹块远离轴线的径向移动。
