Abstract
A two-layer multi-strand cord () comprises an internal layer (CI) of the cord made up of J>1 internal strands (TI) and an external layer (CE) of the cord made up of L>1 external strands (TE). The cord satisfies the relationship 95≤MC≤175, where MC=(J×MI+L×ME)/(J+L); MI=200×cos(α)×[Q×(D/2)×cos(β)+P×(D/2)×cos(δ)+N×(D/2)×cos(γ)]/[Q×(D/2)+P×(D/2)+N×(D/2)]; and ME=200×cos(α')×[Q′×(D′/2)×cos(β′)+N′×(D′/2)×cos(γ′)]/[Q′×(D′/2)+N′×(D′/2)], where D, D′, D, D′, and Dare in mm, α and α′ are the helix angle of each internal and external strand (TI), β and β′ are the helix angle of each internal thread (F, F′), δ is the helix angle of each intermediate thread (F) and γ and γ′ are the helix angle of each external thread (F, F′).
