23. A reinforcing cord comprising at least one strand of metal wires for reinforcing an elastomeric product, the metal wires having each a substantially rectangular cross-section defining opposite broad and narrow sides and having rounded edges, the metal wires in the strand contacting one another along their broad sides to provide a strand of a substantially uniform compact rectangular cross-section, the strand being twisted about its longitudinal axis, the sum of narrow sides of the superposed metal wires equals substantially to the breath of the broad side and wherein the ratio of the broad side to a narrow side is between 4 and 1.5.
