    Abstract: 타이어의 벨트부 양측 가장자리 근방에서 복수회 감아서 배열 설치하는 선 직경이 0.20∼0.45㎜의 소선을 4 내지 7개 꼬아 만든 1×n 구조의 타이어 보강용 스틸 코드(1, 10)로서, 이 스틸 코드가 대략 나선 형상 또는 대략 평면 형상의 파형 경향을 가지며, 또한, JIS B7721에 의한 인장 시험에 있어서, 50N의 인장 하중을 부하했을 때의 신장율이 1.2∼2.0%이고, 파형 경향이 소거되어 코드가 실질적으로 직선 형상으로 될 때의 인장 하중이 50∼250N의 범위 내이다. 제로도 벨트 코드로서 타이어에 매입될 경우, 타이어 성형 시의 가황 처리에 있어서 타이어의 직경 방향으로의 팽창에 추종해서 적당히 신장되고, 타이어 성형 후에는 신장 특성이 작고, 타이어의 고속 연속 회전에 의한 타이어의 직경 방향으로의 팽창을 억지할 수 있다.

    Abstract translation: 零度轮胎增强钢丝帘线是通过将四根至七根具有0.20-0.45mm钢丝直径的单根钢丝绞合在一起而形成的,其中钢丝帘线具有基本螺旋或基本上平面的波状变形,其伸长率为1.2%至2.0 在50N的拉伸载荷下拉伸,并且在拉伸载荷为50N至250N时其波形变形消失时变得基本上线性。钢丝帘线适度伸展以追踪硫化期间轮胎沿径向的膨胀 处理并且随后在轮胎的持续高速旋转期间抑制轮胎在径向方向上的膨胀。

    Abstract: This invention discloses a steel cord. The steel cord comprises a plurality of strands twisted together with a cord twist pitch. Each strand comprises a plurality of filaments twisted together with a strand twist pitch. The elongation at break of the steel cord is no less than 5%. The strand comprises a strand twist angle. The steel cord comprises a cord twist angle. When the sum of the strand twist angle and the cord twist angle is between 20 and 29 degree, the structural elongation of the steel cord is no less than 2.0%. When the sum of the strand twist angle and the cord twist angle is between 30 and 38 degree, the structural elongation of the steel cord is no less than 2.5%. When the sum of the strand twist angle and the cord twist angle is between 39 and 48 degree, the structural elongation of the steel cord is no less than 3.0%. Preferably, the structural elongation of the steel cord is no more than 4.0%. The steel cord has high elongation at break, high structural elongation and high rubber penetration. This invention also provides a pneumatic tire comprising the steel cord mentioned above.

    Abstract translation: 本发明公开了一种钢丝绳。 钢丝帘线包括多根绞合在一起的绳股扭绞节距。 每根股线包括多个与股线扭转节距捻合在一起的细丝。 钢丝绳断裂伸长率不小于5%。 股线包括股线扭转角。 钢帘线包括绳扭转角。 当股线扭转角和绳索扭转角之和在20和29度之间时,钢丝帘线的结构伸长率不低于2.0%。 当股线扭转角和绳索扭转角之和在30和38度之间时,钢丝帘线的结构伸长率不小于2.5%。 当股线扭转角和绳索扭转角之和在39和48度之间时,钢丝帘线的结构伸长率不小于3.0%。 优选地,钢帘线的结构伸长率不大于4.0%。 钢帘线具有高断裂伸长率,高结构伸长率和高橡胶渗透性。 本发明还提供一种包括上述钢丝帘线的充气轮胎。

    Abstract: The invention relates to a braided rope for bend-over-sheave applications consisting essentially of n braided primary strands being made of polymeric filaments, which rope has an oblong cross-section with aspect ratio in the range 1.2 - 4.0. Such a rope shows markedly improved service life performance in cyclic bend-over-sheave applications. The invention also relates to the use of a braided rope according to the invention as a load-bearing member in bend-over-sheave applications; and to a system comprising such a rope and at least one sheave with a groove, the dimensions of which groove are adapted to the rope dimensions.
