摘要： A tire manufacturing method includes making a master batch, using the master batch to make a rubber composition, and making a green tire. The master batch is made wherein a carbon-black-containing pre-coagulation rubber latex is coagulated to obtain a coagulum; a compound according to Formula (I) is added to the water-containing coagulum; wherein R1 and R2 each indicates a hydrogen atom, an alkyl group having 1 to 20 carbons, an alkenyl group having 1 to 20 carbons, or an alkynyl group having 1 to 20 carbons, R1 and R2 may be the same or different, and M+ indicates sodium ion, potassium ion, or lithium ion; and the compound according to Formula (I) is dispersed within the coagulum. The green tire is provided with unvulcanized rubber sheeting made up of the rubber composition, chafer(s), carcass ply or plies, and bead filler(s).

摘要： In the building of a carcass structure for tyres of vehicle wheels, the step of reinforcing with a loop at least one annular anchoring structure (10) associated at the axially opposite end edges of a carcass ply is carried out. Said reinforcement step is carried out on at least one radially expandable/contractable service drum (107a, 107b) and comprises the steps of: setting the service drum (107a, 107b) to a predetermined radial dimension selected according to the fitting diameter of the tyre to be manufactured, depositing the loop (5) on the service drum (107a, 107b), loading the annular anchoring structure (10) onto the service drum (107a, 107b) in a radially outer position with respect to the loop (5), radially expanding the service drum (107a, 107b) up to lock in position the annular anchoring structure (10), rotating the service drum (107a, 107b) about a longitudinal axis (X-X) thereof and, during such a rotation, turning the loop (5) up about the annular anchoring structure (10).

摘要： The present invention has an object of providing a pneumatic tire that exhibits better uniformity by improving the wire wound body for constituting the bead core. The pneumatic tire 1 comprises a bead core 5 comprising a wire wound body 10 in which one bead wire 10a is spirally wound in a continuous around a tire rotational axis CL so that a plurality of layers of the bead wire are formed in a radial direction of the tire. The wire wound body 10 comprises a first part 13 and a second part 14. The first part 13 comprises a plurality of layers of the bead wire 10a each circumferentially extending with a constant radius from the tire rotational axis CL. The second part comprises a plurality of layers of the bead wire 10a each circumferentially extending while changing its radius from the tire rotational axis CL.

摘要： A bead core formation apparatus includes a rubber coating device that coats a circumferential surface of a steel wire with rubber, and two cooling rollers around which the rubber-coated wire, which is a steel wire coated with rubber, is wound. The second roller includes a first groove and a second groove around which the rubber-coated wire located at a downstream side of the first groove is wound. The diameter LB of a portion including the second groove is smaller than the diameter LC of a portion including the first groove.

摘要： The invention provides a method and apparatus for easily and efficiently manufacturing a cable bead, which features excellent wire winding performance. In this method, an annular core is held by a core rotating means. Then a reel wound with a wire is revolved in one direction through the inside and the outside of the core by a reel revolving means by holding the reel wound with a wire alternately on one side and on the other side of the core. And a wire is wound helically around the core as the core is rotated in a circumferential direction in association with the revolving motion of the reel.

摘要： A winding apparatus winds a wire around the circumference of a circular former and lays out the wire in an arrangement of columns and rows to form a bead ring. A roller for pressing a wire positioned on the circumference of the former is located on an apparatus frame and movable in a direction along the columns of the wire and a direction along the rows of the wire. A circular cam having cam surfaces is supported by a camshaft that rotates in synchronism with rotation of the former. A cam follower is engaged with the cam surfaces of the cam and moved integrally with the roller in the direction along the columns of the wire and the direction along the rows of the wire. Thus, the cam surfaces act to move the roller in the direction along the columns of the wire.
