METALLDRAHTKABEL ZUR VERSTAERKUNG VON ELASTOMEREN.

摘要

A metal cord (10 or 26) for reinforcing elastomeric articles, such as earth mover tires, comprises a plurality of metal wire-filament strands, including a center strand and multiple peripheral strands (14 through 24) concentrically surrounding the center strand. Each of the center and peripheral strands includes multiple individual wire filaments (26) of similar diameter having identical strand lay direction and length. Each strand has a hexagonally close-packed longitudinally uniform polygonal outline in which filaments are in concentric layers, with each individual filament being tangential to all adjacently surrounding filaments. The peripheral strands are tangential to the center strand and have a predetermined cord lay length and direction either the same as (Lang's Lay) or opposite to that of the center strand.
