| 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. | ||||||

| A braiding apparatus includes a base, a strand supplier supplying a core strand, strand carriers shuttling on the base and providing carrier strands that wrap the core strand and twist together to form a rope, a guiding pulley disposed above the strand carriers to feed the rope to a strand collector, and a control device having a driving source connected to the guiding pulley, at least one recognition unit arranged on the guiding pulley, a sensor disposed relative to the guiding pulley, and a controller electrically connected to the sensor and the driving source. The sensor counts the number of the recognition unit passing the sensor when the guiding pulley rotates to measure lengths of divided sections of the rope. Concurrently, the controller controls the driving source and the guiding pulley to have different rotational speeds, thereby controlling different braid densities of different sections of the same rope precisely. | ||||||

| PROBLEM TO BE SOLVED: To prevent core deformation generated during rim assembly while ensuring corrosion resistance and air leak resistance in a tire manufactured by a core method.SOLUTION: A bead core is composed of inner and outer core pieces in a tire axial direction and sandwiches an inner end of a carcass ply in the radial direction therebetween. The inner and outer bead pieces are comprised of a spiral body formed by winding bead wire from the inside in the radial direction in a spiral manner. The bead wire is composed of a core section formed by twisting core strand and a sheath section formed by twisting sheath strand around the core section. The core strand and/or sheath strand include embossed strand. A twisting direction and a twisting pitch Pc of the core strand are set to be the same as a twisting direction and a twisting pitch Ps of the sheath strand. | ||||||
