A strip (100) intended for the reinforcement of the wall of high pressure hoses or flexible pipes is presented. The strip (100) comprises multiple wires (102) arranged side-by-side and held together by means of a hardened adhesive (104) originating from a waterborne dispersion. Different embodiments are presented wherein the wires (102) are embedded in the hardened adhesive (104), or wherein only one side of the strip (100) is covered with hardened adhesive (104) or wherein the hardened adhesive (104) is present only between the wires (102) and not on the surfaces (S1, S2) delineating the strip (100). In one preferred embodiment the wires (102) are flattened with the flats being parallel to the surfaces (S1, S2) of the strips (100).
