Abstract:
PROBLEM TO BE SOLVED: To provide a pneumatic radial tire for suppressing occurrence of a separation trouble due to core removal of a steel cord while suppressing growth in an outer diameter. SOLUTION: In the pneumatic radial tire using a steel cord S comprising a core 10 formed by one steel filament 11 without formed with permanent deformation and a plurality layers of sheathes 20, 30 formed by a plurality of steel filaments 21, 31 twisted around the core 10 in the same direction and same pitch in the densest state as a reinforcement material of a tire constituent member, at least one line part 41 extending spirally is processed on the surface of at least one steel filament out of the steel filaments 11, 21 constituting the core 10 and the innermost side sheath 20 of the steel cord S.

Abstract:
PROBLEM TO BE SOLVED: To provide hybrid layered cables which can be used to reinforce at least one crown protection ply for tires fitted on heavy vehicles or earthmovers, and others to reinforce the tire beads in light motorised vehicles such as motorcycles, and a composite fabric usable as a crown protection ply for such heavy vehicles or earthmovers, a bead wire intended to reinforce the tire beads, and the tires. SOLUTION: The hybrid layered cable (C) comprises a non-metallic internal layer (C i ) and an unsaturated external layer (C e ) comprising plural strands each of which is at least in part metallic and which are wound in helix around the internal layer, the cable having a relative elongation at break At, measured in tension in accordance with the standard ISO 6892 of 1984, which is higher than 7%. The internal layer is composed of at least one material having a relative elongation at break Ar at 20°C in excess of 6%. COPYRIGHT: (C)2010,JPO&INPIT
