摘要： A method of making a green tire comprises: winding a carcass ply of rubberized cords around a building drum into a substantially cylindrical body; pressing the cylindrical body against the building drum through the entire circumference not to allow the carcass cords to move axially and circumferentially of the drum; constricting edge portions of the substantially cylindrical body so that the outer diameter thereof is decreased; setting a bead core around each of the constricted edge portions; folding back the edge portions around the bead cores; releasing the cylindrical body from the pressing against the building drum after the edge portions are constricted at the earliest; and swelling a main portion of the cylindrical body between the bead cores while decreasing the width between the bead cores.

摘要： A pneumatic tire has a tread portion, a pair of axially spaced bead areas and a pair of sidewalls. A body ply carcass extends axially between the bead areas and contains three body ply layers which turn-up about the bead areas from inside to outside. Two of the body ply layers are of equal axial lengths with the third body ply layer being considerably less or greater than the other two layers. The highest turn-up end of at least one of the body ply layers has a height of between 42% and 55% of the tire section height.

摘要： A diameter of a wheel to which a tire is fitted is made large, and an inner circumferential space is widened, so that a brake having a large size can be arranged in such large inner circumferential space, and moreover, a spring constant can be lowered due to formation of holes to both bilateral side surfaces of the tire, whereby a cushioning performance can be made high and travelling feeling can be made comfortable. For this purpose, there is provided a cushion tire formed from a rubber material without being provided with an airspace inside the tire, in which an aspect ratio, which is a ratio of a sectional height of a tire with respect to a width of the, is set to 15 to 80%, and a number of holes are formed in both bilateral side surfaces of the tire along a circumferential direction thereof.

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.

摘要： An apparatus for manufacture of a tire, the apparatus including a drum with shoulder having a generally cylindrical main receiving surface to receive the products to be assembled, the main receiving surface being radially retractable. The drum has a shoulder axially to the side edges of said main receiving surface. The drum is mounted on a shaft. At least one associated axially movable side crown is mounted coaxially with the drum. The drum has a lateral protuberance coaxially juxtaposed to at least one of its shoulders. The side crown is axially slidable at least partly under the lateral protuberance, the lateral protuberance forming a quasi-cylindrical support surface whose outside diameter is smaller than the diameter of the main receiving surface. The side crown has a substantially cylindrical outer surface capable of passing axially outside of the lateral protuberance.

摘要： Expandable drum for constructing a green carcass of a tire has a periphery and includes a plurality of metal segments positioned to form a substantially cylindrical arrangement, adapted for radial expansion and compression. A thick-walled casing, positioned over the plurality of metal segments, forms the drum periphery. The thick-walled casing includes rubber and a plurality of voids arranged to have an outer periphery in the thick-walled casing. An evacuating pump is coupled to the plurality of voids. The plurality of voids form suctioning voids to suction the green carcass onto the drum periphery during compression of the drum periphery, and are coupled at radially outermost extents to a network of grooves arranged to provide wave-free and smooth contraction of green carcass during its compression, thereby avoiding bulges and creases in contracting green carcass. Radially innermost extents of the voids are coupled to evacuating pump to create vacuum in the grooves.
