摘要： 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.

摘要： 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.
