摘要:
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.

摘要:
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.
