Abstract

A steel cord (10) adapted for the reinforcement of elastomeric products comprises a core strand (12) and a layer of outer strands (14) arranged around the core strand (12). The core strand (12) comprises a core and at least a layer arranged around the core. The core further comprises one to three core filaments and the layer further comprises three to nine layer filaments. The core strand (12) has a first wave form and each filament of the outer strands (14) has a second wave form such that the first wave form is substantially different from the second wave form. This allows to guarantee full rubber penetration.
