Abstract: The method includes a step (a) of geometric characterization of the profile, during which a first set of geometric remarkable points prepresenting the shape of the profile is provided. In a step (b) of functional characterization of the profile, a second set of functional remarkable points linked to the laying laws which specify the conditions for laying the tire component is provided. The remarkable points are stored in a path chart. At step (c) a series of equidistant virtual points, referred to as “potential guide points”, is defined on the profile, from the first functional remarkable point to the last functional remarkable point. Then, at step (d), the size of the path chart is reduced by applying to the path chart one or more selection criteria in order to select some of the potential guide points and remarkable points.

Abstract: This manufacturing method of a pneumatic tire having a tread reinforcing layer reduces tire mass while maintaining the durability performance of the tire. A tread reinforcing layer formation step includes a winding step for winding belt-shape plies around an approximately cylindrical winding surface. The winding step involves: a first winding step in which, with the side edges of the belt-shape plies spaced from one another, said belt-shape plies are spirally wound from a first end located on one side of the tire in the axial direction, to a second end located on the other side of the tire in the axial direction; and a second winding step in which, with the side edges of the belt-shape plies spaced from one another, said belt-shape plies are spirally wound from the second end to the first end in the direction opposite that in the first winding step. A lattice-form tread reinforcing layer is formed that has gaps substantially rhombic in shape and bounded by the belt-shape plies.

Abstract: A rubber strip is bonded with high accuracy to the surface of a non-linear cylinder-like wound body. The space occupied by the device is reduced. Provided is a transporting conveyor having a transporting belt guided rotatably by guiding rollers. A transporting surface of the transporting belt is provided with a transporting surface width centerline extending in a straight line over the entire length thereof. The guiding rollers are distributed into forward-side guiding rollers and backward-side guiding rollers in the transporting direction. Since the forward-side guiding roller is held tiltibly around the transporting surface width centerline, the transporting surface forms a twistable twisting transporting surface portion between a forward-side transporting surface portion supported by the forward-side guiding roller and a forward-side transporting surface portion supported by the backward-side guiding roller.

Abstract: In the invention, at least a tire outer circumferential side portion of a tread portion is formed of a non-conductive rubber layer. The non-conductive rubber layer is formed by winding and laminating a non-conductive rubber ribbon along a tire circumferential direction. A conductive layer is provided on an outer circumference of the non-conductive rubber ribbon, and the conductive layer continuously and spirally extends along the tire circumferential direction, and is exposed on a tread surface from a bottom surface of the non-conductive rubber layer toward a tire outer circumferential side. Accordingly, an electricity generated in a vehicle body is discharged to a road through the conductive layer. Since the conductive layer is scattered within the non-conductive rubber layer and exposure on the tread surface is preferably secured, it is possible to achieve an excellent conductivity.

Abstract: An unvulcanized rubber member passed from the transfer terminal end of a liner to the outer peripheral surface of a winding roller is transferred and press-fitted to a winding body by rotating the winding roller. By this, the unvulcanized rubber member is transferred from the transfer terminal end of the liner to the winding body while being restrained by an outer peripheral surface of the winding roller. Thus, even if vibration is applied to a transfer means due to a diagonal waving, the winding position and the wound shape of the rubber member can be maintained substantially unchanged.

Abstract: A method and apparatus for building a green tire or a tire component member by winding and laminating a rubber strip on a rigid core or a building drum. The apparatus includes a flattening roll and a rubber strip winder. The flattening roll flattens a projection of a stepped portion produced by overlapping portions of the rubber strip, and a roller of the flattening roll is moved so that it is constantly located at a given position with reference to the rigid core or building drum. The flattening roll moves in a direction opposite to a moving direction of the rubber strip winder during helical winding of the rubber strip on the rigid core or building drum.
