  • Tire comprising cables for reinforcing the carcass having low perviousness, and textile threads associated with the carcass reinforcement
    Patent number: 9889707
    Abstract: A tire having a radial carcass reinforcement, composed of at least one layer of metal reinforcing elements, the said tire comprising a crown reinforcement, itself topped radially by a tread, the said tread being joined to two beads via two sidewalls. The metal reinforcing elements of at least one layer of the carcass reinforcement are cords exhibiting, in the “permeability” test, a flow rate of less than 20 cm3/min and at least one layer of the carcass reinforcement is provided, on at least one face, with textile threads exhibiting, in the “permeability” test, a flow rate of between 1 and 3 cm3/min.
    Type: Grant

  • Tire comprising carcass reinforcing cords of low permeability and textile threads associated with the carcass reinforcement
    Patent number: 9108465
    Abstract: A tire having a radial carcass reinforcement, comprised of at least one layer of metal reinforcing elements, said tire comprising a crown reinforcement, which is itself covered radially with a tread, said tread being joined to two beads via two sidewalls. The metal reinforcing elements of at least one layer of the carcass reinforcement are non-hooped cords having, in the permeability test, a flow rate of less than 20 cm3/min and at least one layer of the carcass reinforcement being provided on at least one side with textile threads oriented mainly along a direction parallel to that of the metal reinforcing elements of said at least one carcass reinforcement layer, said textile threads being corrugated about this main direction.

  • TIRE COMPRISING CABLES FOR REINFORCING THE CASING HAVING LOW PERVIOUSNESS, AND TEXTILE THREADS ASSOCIATED WITH THE CASING REINFORCEMENT
    Publication number: 20140345775
    Abstract: A tire having a radial carcass reinforcement, composed of at least one layer of metal reinforcing elements, and having a crown reinforcement, itself topped radially by a tread, the said tread being joined to two beads via two sidewalls. The metal reinforcing elements of at least one layer of the carcass reinforcement are cords exhibiting, in the “permeability” test, a flow rate of less than 20 cm3/min and at least one layer of the carcass reinforcement is provided, on at least one face, with non-continuous textile threads composed of two parts, one end of a textile thread being positioned on the turn-up of the said at least one layer of reinforcing elements around the bead wires and the other end of a textile thread being radially interior to the orthogonal projection of the shoulder end onto the said at least one face of the said at least one layer of the carcass reinforcement.

  • Device and process for manufacturing undulating plies
    Publication number: 20060191618
    Abstract: Process and device intended for the production of an undulating ply (O) formed of a ply of rubber mix reinforced by reinforcement cords (R) arranged side by side in the longitudinal machine direction at a given pitch, in which ply the reinforcement cords (R) form, in the plane of the ply, undulations in the transverse direction of a controlled amplitude and period. This device comprises means for delivering, a continuous straight-cord ply (D), means (1) for undulating the reinforcement cords in the plane of the ply, means (2) for applying retaining cords (B) in the longitudinal direction of the ply.
