Abstract: The present invention relates to a asymmetric cap ply reinforcement cord comprising yarns having yarns with two different linear density values in range of 1300-1500 dtex and 850-100 dtex in the cap ply reinforcement layer that is located between the tread and the belt package in a pneumatic radial vehicle tire comprising a tread and a belt package, and that is formed by winding spirally as strip comprising at least two cords such that it will make 0 to 5° angle with the equatorial plane on the said belt package.

Abstract: The present invention relates to a novel tire cord reinforcement made of ultra high modulus aramid fibers which has bi-elastic tensile properties. The cord includes at least two plies, and there is a spacing between the cord plies. The cord twisting improves bending and compression fatigue resistance of the aramid, but at the same time reduces the modulus and strength too.

Abstract: A dipped and heat-set aramid cord, comprising a plurality of cord plies having a spacing between the plurality of cord plies, wherein a TASE at 2.0% elongation of the aramid cord is less than 2.0 cN/dtex; wherein the spacing between the plurality of cord plies is more than 10% and less than 80% of a cord diameter (D) of the cord plies.

Abstract: A dipped and heat-set carbon fiber cord, including a plurality of cord plies having a spacing between the plurality of cord plies. A TASE at 2.0% elongation of the carbon fiber cord is less than 2.0cN/dtex. The spacing between the plurality of cord plies is longer than 15% and shorter than 80% of a cord diameter of the plurality of cord plies.

Abstract: The present invention relates to a novel polyester tire cord reinforcement which has bi-elastic tensile properties. The tire cord includes at least two cord plies, and there is a spacing between the cord plies. Such a novel bi-elastic polyester tire cord improves high speed durability and significantly eliminates flatspotting when used as a cap ply in pneumatic radial tires.

Abstract: A two or three-ply nylon 6.6 cord having a breaking elongation of 8 to 12% and a minimum tenacity of 9 g/dtex is disclosed in the present invention. The two or three-ply nylon 6.6 cord is used as tire reinforcement, in particular as cap ply spirally wound on belt package with 0° to 5° to the equatorial plane of the radial pneumatic tire.

Abstract: Pneumatic radial tire (1) having improved high speed durability and low flatspot feature, and which has polyethylene terephthalate cap ply reinforcement layer (6). The objective is to provide a pneumatic radial tire (1) wherein the pressure on the belt package (5) is increased at high speed and high temperature by increasing the thermal shrinkage force of the cap ply cord.

Abstract: A tire cord fabric having paired cords used as warps. The fabric is suitable for use in pneumatic tires as carcass and cap ply reinforcement, enabling the use of less rubber and higher cord content in a specified cord-rubber composite volume.

Abstract: The present invention relates to a reinforcing belt package for radial vehicle tires (1) which is wound between the tread and the carcass in tires used in motor vehicles, and essentially comprises at least one circumferential belt (2), which is formed by arranging metallic cords and polymeric cords next to each other in an alternating way, covered above and below with a rubber layer (3). This reinforcing belt package increases the cornering resistance and the life of the tire.

Abstract: The present invention relates to a tire cord fabric (1) which is used as reinforcement in vehicle tires (L) and wherein the cord (2) twists within its structure vary depending on the area to which they will correspond, and a production method thereof. The processed cords used as warp yarns in the inventive tire cord fabric (1) are produced by twisting the cord with initial twist (K) again and fixing from the twist points (4) with thermal, mechanical and/or chemical methods so that the twist levels of the twist zones (3) having different twists do not change.

Abstract: Tire reinforcement material (1) formed of cords or yarns (2, 3, 4, 5) with different elasticity moduli and which is gained bielasticity property depending on the different thermal shrinkage (TK, AS) properties thereof. To provide a tire reinforcement material (1) which has the process and performance behaviour of the classic hybrid cord, and at the same time a reduced thickness of the fabric (gauge reduction). It allows the production process and performance properties of the tire reinforcement fabric to be optimized independent from each other.

Abstract: A tire cord fabric (1) which comprises alternate cords (2,3) with different tensile extensibilities is used as carcass reinforcement in radial pneumatic tires. The tire cord fabric (1) is formed by cords (2, 3) having different tensile extensibilities and is used as reinforcement in radial pneumatic tires to provide a sidewall area with an ondulated carcass structure.
