  • Patent number: 5014760
    Abstract: High strength steel wire for use e.g. in tire reinforcement is treated so as to have a cementite free surface region. This can be achieved by electroplating or other coating methods, or be decarburizing the surface. The wire has increased resistance to hydrogen embrittlement and corrosion fatigue. The wire with its ferrous surface region is then covered with a rubber adherent outer layer of e.g. brass.

    Inventors: Martin Bombeke, Paul Dambre
  • Patent number: 4952249
    Abstract: After a last patenting operation at a first diameter d.sub.1 a steel wire is (a) drawn by means of a lubricant to an intermediate work hardened state at an intermediate diameter d.sub.2, (b) coated at said intermediate diameter d.sub.2 and work hardened state with a brass alloy, (c) drawn at said intermediate diameter d.sub.2 and work hardened state to a final diameter d.sub.f. This process may increase the ultimate tensile strength of the steel wire and may reduce the frequency of fractures during the drawing operation. The process also may provide steel wires with an improved adhesion to rubber.

  • Patent number: 4854032
    Abstract: A method of manufacturing a steel wire with high tensile strength having improved bending and torsional ductility properties useful as a reinforcement wire or cord, especially for rubber products such as tires, comprising providing steel comprising less than 0.015%, preferably less than 0.010%, and most preferably less than 0.008% by weight sulfur and drawing said steel beyond normal drawing limits into a wire having a tensile strength in N/mm.sup.2 of at least 2250-1130 log d where d is the wire diameter in millimeters, and optionally, depositing a covering layer of rubber adherable material such as brass on the drawn wire.

  • Patent number: 4829760
    Abstract: A steel cord comprises a central bundle of three twisted steel filaments (1) with a diameter d.sub.1 and nine steel filaments twisted around said central bundle with the same twist pitch and twist direction as the central bundle. Three filaments (2) of said nine steel filaments have a diameter d.sub.2 and contact two adjacent steel filaments of the central bundle. Six steel filaments (3) of said nine steel filaments have a diameter d.sub.3 and contact both one steel filament of the central bundle and one steel filament of the three filaments with diameter d.sub.2. The ratio d.sub.2 /d.sub.1 is greater than 1.05 and smaller than 1.16. The raio d.sub.3 /d.sub.1 is greater than-0.205=0.814.times.d.sub.2 /d.sub.1 and smaller than-0.105+0.814=d.sub.2 /d.sub.1.

  • Patent number: 4759806
    Abstract: A process for manufacturing pearlitic steel wire, particularly with fine diameters and for use in reinforcing rubber vehicle tires. The wire is subjected to a patenting treatment before being drawn down to its final diameter, but is held at the transformation temperature for no more tha 5 seconds after transformation has taken place. Such a step renders the wire capable of being subjected to true strains of more than 3.0 and achieving tensile strengths of 3000 Nmm.sup.-2 or more. The wire may be cooled from the transformation temperature via a first stage in which the temperature is reduced to 400.degree. to 450.degree. C. over a period of time not less than 3 seconds.

  • Patent number: 4737392
    Abstract: Bending and torsional ductility of high tensile reinforcement steel wire or cord, especially for rubber products, such as tires, is improved by taking care that the steel compositions that are currently used for such application, have an extra low sulphur content, i.e. below 0.015%, preferably below 0.010%.

  • Patent number: 4651513
    Abstract: A steel cord for reinforcing rubber products such as truck tires comprises a plurality of steel wires twisted together to form a multiwire layered cable construction having two or more successive wire layers around a common core. The wires of the outer layer are covered by a rubber adherable coating of, e.g. brass, and the wires (shaded) of the layer inwardly adjacent the surface layer are covered by a corrosion resistant coating, such as zinc or a zinc alloy.

  • Patent number: 4612792
    Abstract: In order to improve the fatigue resistance of a cable, particularly a rubber adherable cable for reinforcing rubber articles such as vehicle tires, substantially uniformly distributed residual compressive stress is induced in substantially the complete peripheral zone of the wires making up the cable. The stress may be induced by submitting lengths of the cable to a number of elementary bending-unbending operations in considerably different planes and simultaneously tensioning the cable.

  • Patent number: 4481996
    Abstract: In order to improve the fatigue resistance of a cable, particularly a rubber adherable cable for reinforcing rubber articles such as vehicle tires, substantially uniformly distributed residual compressive stress is induced in substantially the complete peripheric zone of the wires making up the cable. The stress may be induced by submitting lengths of the cable to a number of elementary bending--unbending operations in considerably different planes and simultaneously tensioning the cable.
