摘要： In order that spaces, including a space in the central portion, inside a steel cord used as a reinforcement by being embedded in a tire or the like are filled with an uncured rubber, the uncured rubber is coated on plural steel core filaments which are then stranded to form a single layer steel cord, the core then being stranded with uncoated outer layer filaments. Consequently, it is possible to exhibit satisfactory corrosion resistance and satisfactory fatigue resistance as a steel cord, shorten a curing time in tire component assembling or the like to attain energy saving and prolong the life of a steel cord itself and the life of a tire or the like using the same as a reinforcement. Further, production can be performed at low cost.
摘要翻译：为了将包含在中心部分中的空间，用作通过嵌入在轮胎等中的加强件的钢帘线内的空间填充有未固化的橡胶，将未固化的橡胶涂覆在多个钢芯长丝上绞合以形成单层钢帘线，然后将芯与未涂覆的外层丝绞合。因此，作为钢帘线，可以显示出良好的耐腐蚀性和令人满意的耐疲劳性，缩短轮胎部件组装等中的固化时间，以达到节能，延长钢丝绳本身的寿命和轮胎的使用寿命使用与加强件相同的类似物。此外，可以以低成本进行生产。

摘要： A steel cord is configured so that, when the steel cord is used as a tensile cord for an elastic crawler, a center-core dislocation and the early breakage of the wires of a core are prevented. A steel cord comprises: a core which comprises a single core strand, and a sheath which is formed by twisting together six sheath strands arranged around the core. The core strand has a layer-twisted structure comprising: a center-core portion which is formed by twisting three core wires together; and an external layer portion which is formed by twisting together eight to nine core wires arranged around the center-core portion. The sheath strands each have either a bundle twisted structure which is formed by twisting twelve to nineteen sheath wires or a multi-layer twisted structure which is formed by twisting twelve to nineteen sheath wires in layers. The diameter (dc) of the core wires is greater than the diameter (ds) of the sheath wi res. The average gap (Gc) between the core wi res of the external layer portion is 0.015 mm or greater, and the average gap (Gs) between the sheath strands is 0.1 mm or greater.
