Abstract: A steel cord (1) for the reinforcement of rubber articles such as tires comprises a core consisting of two to four steel filaments (2) and a layer of steel filaments (3, 4) around the core. All the filaments have a diameter between 0.15 and 0.40 mm and are twisted in the same direction and at the same pitch. The cord has substantially over its entire length cross-sections where the accumulated gaps between adjacent layer filaments are at least 0.03 mm. At least one filament of the layer has been preformed differently from the other filaments. Core migration is avoided.

Abstract: The present invention prevents core deformation at a time of mounting a tire on a rim while corrosion resistance and air-leak resistance are assured in a tire made with a inner molding process. A bead core comprises axially inner and outer core pieces, and a radially inner end part of a carcass ply is held therebetween. The axially inner and outer bead pieces are composed of a spiral-wound body in which a bead wire has been spirally wound and overlapped. The bead wire comprises a core part in which core strands have been twisted together and a sheath part in which sheath strands have been twisted together around the core part. The core strands and/or the sheath strands comprise an embossed strand. The twisting direction and twisting pitch (Pc) of the core strands are the same as the twisting direction and twitching pitch (Ps) of the sheath strands.

Abstract: The invention relates to a metal cord (C-1) comprising three concentric layers (C1, C2, C3) with an M+N+P structure, a first layer or core (C1) having a diameter d
c consisting of M wire(s) (10) of diameter d
1 , around which N wires (11) of diameter d
2 are wound together in the form of a helix according to a pitch v>2, in a second layer (C2), around which P wires (12) having a diameter d
3 are wound together in the form of a helix according to a pitch p
3 , in a third layer (C3), in which at least some of the gaps or capillaries (14) of the cord, arranged between the core (C1) and the N wires (11) of the second layer, and between the core wires themselves when M is higher than 1, and also between the N wires (11) of the second layer and the P wires (12) of the third layer, contain a filling rubber (13) based on an unsaturated thermoplastic elastomer, especially a styrenic thermoplastic elastomer (TPS) such as a block copolymer SBS, SBBS, SIS or SBIS. Such a thermoplastic elastomer, implemented in its melted state, does not cause any unwanted sticking problems in the event of the filling rubber overrunning outside the cord after production; its unsaturated and therefore (co)vulcanisable character enable it to be excellently compatible with diene rubber matrices, especially natural rubber, such as those usually used as calendering rubber in the metal fabrics used to reinforce tyres.

Abstract: 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.
