摘要： An annular metal cord and an endless metal belt are provided which have superior breaking strength and which are easy to be produced.
The annular metal cord includes an annular core portion 3 and an outer layer portion 4. The annular core portion 3 is formed by connecting together both ends of a first strand material 1 which is made up of six twisted first metal filaments 5. The outer layer portion 4 is formed by winding spirally a second strand material 2 which is made up of six twisted second metal filaments 6 around the annular core portion 3. The second strand material 2 is wound at a predetermined winding angle relative to a center axis of the annular core portion 3, and a winding initiating end portion and a winding terminating end portion thereof are connected together. Since it is not that six second strand materials 2 are not wound but that the second strand material 2 is wound six rounds, there only has to be the single second strand material 2, and there is only one connecting portion. As a result, the breaking strength of the annular metal cord can be made large, and the production thereof can be facilitated.摘要翻译： 提供环形金属线和环形金属带，其具有优异的断裂强度并且易于制造。 环形金属线包括环形芯部3和外层部分4.环形芯部3通过将由六根扭曲的第一金属细丝5组成的第一股线材料1的两端连接而形成。外层 部分4通过螺旋地卷绕由六根扭曲的第二金属细丝6围绕环形芯部分3组成的第二股线材料2形成。第二股线材料2相对于环形芯部分的中心轴以预定的卷绕角度卷绕 芯部3和绕组起始端部及其绕组终止端部连接在一起。 由于不是六根第二股线材料2不被卷绕，而是第二股线材料2缠绕六圈，所以仅需要单个第二股线材料2，并且只有一个连接部分。 结果，能够使环状金属线的断裂强度大，能够促进其生产。

摘要： There are provided an annular concentric stranded bead cord which can realize a reduction in weight while ensuring its strength, a method for manufacturing the same and a vehicle tire.
The manufacturing method is a method for manufacturing an annular concentric stranded bead cord 2 by forming a sheath layer 13 by winding spirally a lateral wire 12 round an annular core 11. After the sheath layer 13 has been formed, the lateral wire 12 is annealed in a pressure-reduced inactive gaseous atmosphere with an annealing quantity which exceeds a heating quantity (temperature × time) which is necessary for vulcanization of a vehicle tire 1 with the annular concentric stranded bead cord embedded in a rubber of the vehicle tire 1 when building the same and is shaped so that "Diameter shaping ratio (%) = H/D × 100" becomes 20% or larger and 105% or smaller.摘要翻译： 有设置在环形设计同心绞股胎圈帘线能够在实现重量的减少，同时确保其强度，其制造和车辆轮胎的方法。 的制造方法是用于制造环形设计同心绞股胎圈帘线2的由螺旋地缠绕侧线环形设计芯11的鞘层13之后的12轮形成护套层13已经形成的方法中，横向线12在退火 与在退火量的减压惰性气体气氛中超过一个加热量（温度×时间）所有这是必要的具有嵌入在车辆轮胎1的橡胶。当构建环形设计同心绞股胎圈帘线的车辆轮胎1的硫化 相同的，并且成形为使得“直径成形率（％）= H / D×100”变为20％或更大和105％或更小。
