摘要： A method for manufacturing a motorcycle tire comprises: building a raw tire main body, building a breaker, sticking the breaker, and building a band. The building of the breaker comprises: moving two cylindrical support rings to operating positions, swelling the raw tire main body to have its crown portion protruding from the support rings through a gap therebetween, and winding a breaker ply material on the support rings to form a cylindrical breaker ply whose inner surface is adhered to the raw tire main body. The sticking of the breaker comprises: expanding a profiled deck to swell the raw tire main body into a second swollen state, and turning down both edge portions of the breaker while being supported by the profiled deck. The building of the band comprises: spirally winding a tape on the curved breaker ply while being supported by the profiled deck.

摘要： A pair of annular inserts of elastomeric material is circumferentially applied by spiraling around a laying surface of an auxiliary drum. Then a plurality of strip-like elements disposed in parallel side by side relationship with each other in the circumferential extension of the laying surface is applied onto the auxiliary drum, so as to form at least one first belt layer. Respectively opposite end portions of each strip-like element are radially superposed, each against one of the annular inserts, so that each of the annular inserts projects from a respective end edge of the strip-like element. The cap structure formed on the auxiliary drum is coupled to a carcass structure through toroidal conformation of the latter, in such a manner that the radially external ends of sidewall portions previously manufactured on the carcass plies are associated with the axially external ends of the annular inserts.

摘要： The strip is formed of a single layer including a first layer arranged in a tire innermost layer or composite layers of the first layer and a second layer disposed adjacently to a carcass ply and made of a thermoplastic elastomer composition. The first layer is a thermoplastic elastomer composition containing a styrene-isobutylene-styrene block copolymer and a tackifier, a butyl-based rubber and a natural rubber. The strip has a strip main body having a thickness (T1) of 0.02 to 1.0 mm and ear portions formed on opposite sides of the strip main body. The ear portions have a thickness (T2) smaller than the thickness (T1) and a width (W2) of 0.5 mm to 5.0 mm.

摘要： A manufacturing method using a rigid core, wherein high-speed endurance performance is enhanced while breakage of band cords is suppressed. This method for manufacturing a pneumatic tire includes a green tire formation process for forming a green tire by affixing tire-constituting members in sequence to a rigid core. The green tire formation process includes a band ply formation step for winding a ribbon-shaped strip in which a band cord sequence is coated with a topping rubber into a helical shape. The band cord comprises a composite cord in which first strands of aramid fiber and second strands of heat-shrinkable organic fiber are twisted together. The stress-elongation curve of the composite cord has a low-elasticity region from the origin to the inflection point, and a high-elasticity region past the inflection point. The elongation of the composite cord is in the range of 0.9-3.3% at the inflection point, and the modulus of the composite cord is in the range of 11-31 N/% in the low-elasticity region.

摘要： Method of manufacturing a tire (1) by winding contiguous strips onto a rotary form at a pitch and in a number of turns that is suited to the desired profile. The method comprises steps that include laying a strip to form the sublayer (13) onto the plies (15) that form the crown reinforcement belt, the strip being made of a rubbery material that is a poor conductor of electricity, laying one or more strips to form the first part of the tread (11A), these being positioned axially on one side of the tire, the strip or strips being made of rubbery materials that are poor conductors of electricity, and laying a strip to form the insert (10) and that is laid in such a way that at least one radially interior turn (100) is in contact with the sublayer (10), the strip being made of a rubbery material that is a conductor of electricity. A localized pitch offset (130) is created when winding the strip that forms the sublayer (13), the pitch offset being positioned axially in line with the radially interior part of the insert (10), so as to make the turns non-contiguous.

摘要： A method and apparatus for manufacturing an annular tire component such as a tire bead includes locating a toroidal support; placing an ejector nozzle in an interference relationship to the toroidal support; and simultaneously ejecting through the nozzle a continuous stream of an elastomeric belt component material in a suitably fluid state and a continuous length of at least one thread component disposed within the stream onto the toroidal support in a predetermined bead configuration. The bead configuration is at least partially defined by a relief in the nozzle ejection port and by the toroidal support onto which the bead is formed. Rotation of the toroidal support may be coupled with the simultaneous ejection of the elastomeric component and thread component in order to create an annular bead structure. A tire may be constructed having a desired bead configuration and location by means of the method and apparatus.

摘要： A reinforcement strip is laid on a rotating receiving surface during the manufacture of a tire. The strip passes through a guide which is moved alternatingly transversely relative to a travel path of the strip, whereby the strip is laid in an undulating pattern on the receiving surface. The amplitude of the alternating transverse movement is varied as a function of a ratio of: (a) the speed of a portion of the strip approaching the guide, and (b) the speed of the receiving surface. Between the guide and the receiving surface the strip is pivoted by 90 degrees about the strip's longitudinal axis so as to be laid tangentially on the receiving surface.

摘要： A method of manufacturing a carcass structure for vehicle tires includes the steps of making at least one carcass ply by deposition of elongated sections circumferentially distributed on a toroidal support and applying annular reinforcing structures to a region close to inner circumferential edges of the at least one carcass ply. Each of the elongated sections extends in a U-shaped configuration around a cross-sectional outline of the toroidal support to define two side portions mutually spaced apart in an axial direction and one crown portion extending at a radially outer position between the side portions. Each of the elongated sections is laid down substantially in a plane parallelly offset relative to a meridian plane of the toroidal support. A related carcass structure and tire are also disclosed.
