  • Steel cord for protection plies of pneumatic tires
    Patent number: 6475636
    Abstract: A steel cord particularly adapted for reinforcement of a protection ply in a tire has under compression in rubber a deformation Wk at instability of at least 3% and is stress-relieved so that its total elongation at rupture in rubber exceeds 3.5%. The steel cord comprises pearlite filaments.
    Type: Grant
    Filed: March 28, 2000
    Date of Patent: November 5, 2002
    Assignee: N.V. Bekaert S.A.
    Inventors: Urbain D'Haene, Marc Eggermont, Yvan Lippens, Dirk Meersschaut
  • STEEL CORD FOR PROTECTION PLIES OF PNEUMATIC TIRES
    Publication number: 20020150786
    Abstract: A steel cord (10) particularly adapted for reinforcement of a protection ply in a tire has under compression in rubber a deformation Wk at instability of at least 3% and is stress-relieved so that its total elongation at rupture in rubber exceeds 3.5%. The steel cord (10) comprises steel filaments (12) having a pearlitic structure.

  • Cord with high non-structural elongation
    Patent number: 5843583
    Abstract: A steel cord adapted for the reinforcement of an elastomer comprises steel filaments of a pearlitic structure. The steel cord has a plastic and elastic elongation at break of x % and a plastic and elastic elongation capability in the vulcanized elastomer of y %, the values x and y fulfilling following equation:y-0.50.ltoreq.x.ltoreq.y+0.50,which means that the total elongation at break does not fall down considerably after embedding the steel cord into an elastomer.

  • Steel strip and method of making
    Patent number: 5198307
    Abstract: A steel strip (1) comprises two to seven round steel filaments (2) lying in parallel adjacent to one another so as to form a single plane of core filaments and one or more filaments (4) which are wrapped around the core filaments in one single wrapping direction. One or more core filaments, individually, or the plane of the core filaments as a whole have residual elastic torsions to such an extent that the strip remains substantially flat over the whole length of the strip if the strip is not subjected to external forces.
    Type: Grant
    Filed: November 20, 1991
    Date of Patent: March 30, 1993
    Assignee: N. V. Bekaert S.A.
    Inventors: Luc Bourgois, Urbain D'Haene, Daniel Van Wassenhove
  • Process for the manufacture of hose or tubing with a high resistance to pressure and fatigue
    Patent number: 4722210
    Abstract: A process for the manufacture of hose or tubing conditions plastic high pressure hose having at least one reinforcing layer of steel wires, cords or longitudinal segments thereof. The hose is internally pressurized for a predetermined period of time which provides a residual permanent elongation of at least 0.5% and increases the interior volume by at least 2% upon release of the pressure.

  • Method of manufacturing fatigue resistant cables
    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.

  • Fatigue resistant cables
    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.
