    Abstract: A steel cord (20) adapted for the reinforcement of rubber products, comprising an inner strand of at least three and no more than seven filaments (22a- 22f) twisted together in a first twist direction with a first twist step and further comprising a layer of filaments (24) twisted around said inner strand in a second twist direction with a second twist step. One of the filaments (22a- 22f) of the inner strand is alternatingly taking the position as core filament. The alternating role of the filaments to function as core filament provides a good mechanical anchorage of this core filament in the steel cord and the outer layer (24) provides an outer surface with a decreased roughness so that processability problems are avoided or at least reduced to a minimum.
