Abstract
A steel wire cord which comprises an assembly of strands each of which comprises a plurality of filaments of steel, said filaments having been drawn to give a reduction in their cross-sectional area of less than 96%, the strand helix angle being not less than 40.degree. and the filament helix angle being not less than 20.degree..
Claims13
A steel wire cord which comprises an assembly of strands each having a plurality of filaments of steel, said filaments having been drawn, after at least one heat treatment, to give a reduction in their cross-sectional area after the last heat treatment, of less than 96%, the strand helix angle being not less than 20.degree. and the filament helix angle being not less than 40.degree..
A steel wire cord reinforced elastomeric article which comprises an assembly of strands each having a plurality of filaments of steel, said filaments having been drawn after at least one heat treatment, to give a reduction in their cross-sectional area after the last heat treatment in the range of 95% to 96%, the strand helix angle being not less than 20.degree. and the filament helix angle being not less than 40.degree., said assembly of strands being embedded in elastomeric material to form a reinforcement thereof.
