Radialer LKW-Reifen und metallischer Kord

摘要

The invention improves rubber permeability while making a cord diameter compact. A metal cord is constituted by a layered structure having a core comprising totally 6 to 12 filaments sectioned into 1 to 4 filament bundles (13), and a sheath comprising 8 to 15 filaments arranged around the core. Each of the filament bundles includes a waved filament (20) modeled in a two-dimensional wave shape and a non-waved filament (21), in a state before being bundled. The core makes the wave of the waved filament three-dimensional within the core by applying torsion to each of the filament bundles.
