摘要： The invention relates to a method for producing a metal cord having three concentric layers (C1, C2, C3), of the type that is rubberized in situ, i.e. during the production thereof. The cord comprises a first inner layer or core (C1), around which N strands of diameter d
2 are wound together in the form of a helix with a pitch p
2 to form an intermediate layer (C2), N varying between 3 and 12. In addition, P strands of diameter d
3 are wound together around this second layer in the form of a helix with a pitch p
3 to form a third outer layer (C3), P varying between 8 and 20. The method includes the following steps: a first step in which the core (C1) is coated with a rubber composition known as "filling rubber" in the non-crosslinked state; a step in which the N strands of the second layer (C2) are assembled and twisted around the thus coated core (C1), so as to form an intermediate cord, known as the "core strand" (C1+C2), at a point known as the "assembly point"; a step in which the P strands of the third layer (C3) are assembled and twisted around the core strand (C1+C2); and a final twist value balancing step. The invention also relates to the device used to implement one such method.

摘要： The invention relates to a three-layer metal cord of L+M+N construction, which can be used to reinforce a tyre carcass reinforcement. The inventive cable comprises: an inner layer C1 with L wires having a diameter d1, L varying between 1 and 4; an intermediate layer C2 which surrounds the inner layer, with M wires having a diameter d2, which are helically wound together with a pitch p2, M varying between 3 and 12; and an outer layer C3, which surrounds the intermediate layer C2, with N wires having a diameter d3, which are helically wound together with a pitch p3, N varying between 8 and 20. The cord is characterised in that a sheath, which is made from a crosslinkable or crosslinked rubber composition based on at least one diene elastomer, covers at least the aforementioned intermediate layer C2. The invention also relates to the plastic and/or rubber semifinished products or articles reinforced with one such multilayer cord, such as tyres that are intended for industrial vehicles and, more specifically, heavy vehicle tyres and the carcass bracing plies thereof.

摘要： The invention relates to a method for producing a metal cord having three concentric layers (C1, C2, C3), of the type that is rubberized in situ, i.e. including a composition comprising rubber in the non-crosslinked state, known as "filling rubber". The cord comprises a first inner layer or core (C1), around which N strands of diameter d
2 are wound together in the form of a helix with a pitch p
2 to form an intermediate layer (C2), N varying between 3 and 12. In addition, P strands of diameter d
3 are wound together around this second layer in the form of a helix with a pitch p
3 to form a third outer layer (C3), P varying between 8 and 20. The method includes the following steps: a first step in which the core (C1) is coated with the filling rubber; a first step in which the N strands of the second layer (C2) are assembled and twisted around the thus coated core (C1), so as to form an intermediate cord, known as the "core strand" (C1+C2), at a point known as the "assembly point"; downstream from said assembly point, a second step in which the core strand (C1+C2) is coated with the filling rubber; a second step in which the P strands of the third layer (C3) are assembled and twisted around the thus coated core strand (C1+C2); and a final twist value balancing step. The invention also relates to the device used to implement one such method.
