Abstract: The invention relates to an assembly for a tyre comprising a first fabric, a second fabric and a load-bearing structure comprising filamentary load-bearing elements made of heat-shrinkable textile material connecting the first fabric to the second fabric, the load-bearing filamentary elements exhibit a thermal contraction CT, measured after 2 min at 185° C., greater than or equal to 5%.

Abstract: A reinforcing element includes a single strand of high-modulus textile monofilaments and a single strand of low-modulus textile monofilaments. The strand of high-modulus textile monofilaments and the strand of low-modulus textile monofilaments are wound around each other in a direction D3 with a twist R3. The strand of high-modulus textile monofilaments has a residual twist R1 in a direction D1. The strand of low-modulus textile monofilaments has a residual twist R2 in a direction D2. The residual twists R1 and R2 have a relationship such that: when R2 is substantially non-zero, R1>R2, and when R2 is substantially zero, R1 is substantially non-zero.

Abstract: A high modulus textile cord (50) with at least triple twist (T1, T2, T3) comprises at least N strands (20a, 20b, 20c, 20d), N being greater than 1, twisted together with a final twist T3 and a final direction D2, each strand being made up of M pre-strands (10a, 10b, 10c), M being greater than 1, themselves twisted together with an intermediate twist T2 (T2a, T2b, T2c, T2d) and an intermediate direction D1 opposite to D2, each pre-strand itself consisting of a yarn (5) which has been twisted on itself beforehand with an initial twist T1 (T1a, T1b, T1c) and the direction D1, in which at least half of the N times M yarns have an initial elastic modulus denoted Mi which is greater than 2000 cN/tex. This textile cord can advantageously be used as a reinforcer in tires for vehicles, particularly in the belt or carcass reinforcement of these tires.

Abstract: The reinforcing element (45) comprises an assembly (49) made up: of a multifilament strand made of aromatic polyamide or aromatic copolyamide (46) and of a multifilament strand made of polyester (48). The two strands (46, 48) are wound in a helix around one another, and the reinforcing element (45) is twist-balanced. The twist factor K of the reinforcing element (45) ranges from 5.5 to 6.5 where K is defined by the formula: K=(R×Ti1/2)/957 in which R is the twist of the reinforcing element (45) expressed in twists per metre and Ti is the sum of the counts of the multifilament strands of the reinforcing element (45) in tex.

Abstract: The reinforcing element (36) comprises a single strand (54) of high-modulus textile monofilaments and a single strand (56) of low-modulus textile monofilaments which are wound one around the other in a direction D3 with a twist R3, the strand (54) of high-modulus textile monofilaments having a residual twist R1 in the direction D1, the strand (56) of low-modulus textile monofilaments having a residual twist R2 in the direction D2, the residual twists R1 and R2 being such that: R1>R2 when R2 is substantially non-zero R1 is substantially non-zero when R2 is substantially zero.

Abstract: An aramid textile cord (50) with at least triple twist (T1, T2, T3) comprises at least N strands (20a, 20b, 20c, 20d), N being greater than 1, twisted together with a final twist T3 and a final direction D2, each strand being made up of M pre-strands (10a, 10b, 10c), M being greater than 1, themselves twisted together with an intermediate twist T2 (T2a, T2b, T2c, T2d) and an intermediate direction D1 opposite to D2, each pre-strand itself consisting of a yarn (5) which has been twisted on itself beforehand with an initial twist T1 (T1a, T1b, T1c) and the direction D1, in which at least half of the N times M yarns are aramid yarns. This textile cord can advantageously be used as a reinforcer in tires for vehicles, particularly in the belt or carcass reinforcement of these tires.

This textile cord can advantageously be used as a reinforcer in tires for vehicles, particularly in the belt or carcass reinforcement of these tires.

Abstract: A tyre, which is designed to be able to run flat, includes a carcass reinforcement. The carcass reinforcement includes at least one reinforcing element. Each reinforcing element includes at least one multifilament plied strand made of aramid and at least one multifilament plied strand made of polyester. The at least one multifilament plied strand made of aramid and the at least one multifilament plied strand made of polyester are twisted together.

Abstract: The invention relates to 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. According to the invention, 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, the said textile threads being sized in order to be associated with the said at least one layer of the carcass reinforcement.
