ABSTRACT:
A steel cord reinforcement for elastomers and elastomeric articles comprising a steel cord crimped in a zig-zag fashion used in the warp direction of the reinforcing fabric; the crimps of adjacent warped cords lie in phase, and the wave length p of the crimp and the amplitude c of the crimp are related such that 0.02 p.ltoreq.c.ltoreq.0.07 p; to achieve optimal properties of cord elongation and cord deformation, the relationship S=k p.sup.2 wherein 0.7.ltoreq.k.ltoreq.3, and the stiffness S=10.sup.4 N [.SIGMA.(D.sub.i.sup.4 .times.n.sub.i)] wherein D.sub.i represents the diameter of wire filament "i" in the cord, n.sub.i is the number of wires "i" per warp cord, and N is the number of warp cords per mm width of the fabric.
