  • Publication number: 20140290204
    Abstract: A method of manufacturing a metal cord with two concentric layers of wires is provided. The cord includes an internal layer of M wires, M having a value from 1 to 4, and an external layer of N wires. The cord is rubberized from within in situ. That is, during manufacture of the cord, the cord is rubberized from inside. According to the method, the internal layer is sheathed with rubber or a rubber compound by passing the internal layer through an extrusion head, and the N wires of the external layer are assembled around the sheathed internal layer to form a two-layer cord rubberized from the inside. The rubber is an unsaturated thermoplastic elastomer that is extruded in a molten state, and preferably is a thermoplastic styrene (TPS) type of thermoplastic elastomer, such as an SBS or an SIS block copolymer, for example.

  • Publication number: 20140051312
    Abstract: Rubber composite, and in particular tyre, reinforced with a sized textile material, such as a fibre or a film, at least one portion of which is coated with an adhesive layer, capable of adhering directly via curing (crosslinking) to an unsaturated rubber matrix, such as a natural rubber matrix, characterized in that said layer comprises an adhesive composition or thermoplastic adhesive, in the liquid or solid state, which is based on at least one unsaturated thermoplastic styrene (TPS) elastomer and a poly(p-phenylene ether) (PPE). Such an adhesive based on unsaturated TPS and PPE advantageously makes it possible to replace a conventional textile adhesive of RFL type.
