Elastomeric article with 2+1+9 or 2+1+9+1 metallic cord

摘要

A metallic cord has (a) a core composed of two filaments either parallel or intertwisted with each other, (b) a single filament surrounding the core and (c) a sheath of nine filaments surrounding the core and single filament. Preferably, the diameter of each filament ranges from about 0.15 to 0.4 mm. The cord may reinforce elastomeric articles such as tires, belts and hoses and preferably is used in a belt ply or carcass ply of a pneumatic tire.
