    摘要： Tyre with radial carcass having a breaker structure that comprises two radially overlapped layers (1,2) of metallic fabric reinforced by cords transversally disposed in respect to the circumferential direction of the tyre and crossed together and, on each extremity of said couple of layers, at least a rubberized fabric strip 3 reinforced by metallic cords of high elongation (HE) or very high elongation (VHE) eventually in combination with Hybrid textile cords (Aramide/Polyamide) disposed according to the circumferential direction and having, in the vulcanized tyre, a modulus of elongation of non-increasing value passing from the axially outermost cord to the axially innermost one.
    Said strip 3 is suitably realized by the coupling of cords (axially from the outside to the inside) HE-VHE (High Elongation - Very High Elongation), HE-Hybrid (High Elongation - Aramide/Polyamide) and VHE-Hybrid.

    摘要翻译： 具有径向胎体的轮胎具有断路器结构，该断路器结构包括两个径向重叠的金属织物层（1,2），该层由相​​对于轮胎的圆周方向横向设置并交叉在一起的帘线加强，并且在所述一对层的每个末端， 至少一个由具有高延伸率（HE）或非常高伸长率（VHE）的金属帘线加强的橡胶织物带3，最终与根据圆周方向设置的混合纺织帘线（芳族聚酰胺/聚酰胺）结合，并且在硫化轮胎中， 从轴向最外面的帘线到轴向最内侧的不增加值的伸长模量。 所述条带3适用于通过将帘线（从外部到内部的轴向）HE-VHE（高伸长率 - 超高伸长率），HE混合（高伸长 - 酰胺/聚酰胺）和VHE-混合物的耦合来实现。

    摘要： The metal core used for reinforcing tire beads is consti­tuted by a plurality of coils of wire (16), (17), (18), axially arranged side-by-side and radially superimposed, in which the wire has a straight section of modular shape with two equal and parallel opposite sides (1), (2), the profiles (15) connecting the corresponding ends of the opposite sides having a distance, from the axis of said pair of sides, whose value varies from one side to the other, said variation comprising at least one inversion of value along the development of the profile.
