Abstract: The present invention provides a radial tire forming apparatus capable of being applied to the formation of a carcass band having a large folding length. On a housing for a rollover device of the tire forming apparatus, a plurality of sets of straight rail bearers are fixed at appropriate places, so that a frame provided with rails is advanced toward or retreated from a second forming point on the carcass forming former side by a cylinder fixed to the housing. The diameter of a first rollover ring is slightly smaller than the diameter of a second rollover ring. When the rollover rings are brought closest to each other, the cylindrical portions of the rings enter and lap on each other.

Abstract: A green tire holding device (10) including a frame (12), a rod (14) extending horizontally from the frame (12), and a bladder (16) mounted on the rod (14). The bladder (16) is inflatable to an inflated shape so that it contacts a substantial portion of an inner circumference of a green tire (T) to support the green tire during a pre-curing wait cycle. The green tire holding device (10) can comprise a plurality of rods (14), a plurality of bladders (16), and/or a plurality of bladders (16) on each rod (14). The bladders (16) can be inflated at substantially the same time and/or certain bladders (16) can be deflated independently of other bladders (16). In a tire manufacturing method, the loaded green tire storage device (10) is transported to a doping/curing area with the bladders (16) deflated. At the doping/curing area, the tires (T) are removed from the rods (14), doped, and re-hung on the rods (14). The bladders (16) are then inflated so that the tires (T) are stored on inflated bladders during the pre-curing wait cycle.

Abstract: Within the scope of the manufacturing of a tyre, a belt structure (2) is manufactured by means of strip-like segments (5) each comprising parallel strips incorporated in an elastomeric layer, sequentially laid in mutual circumferential approach relationship onto a toroidal support (3). During the laying of each segment (5), an angular rotation of the toroidal support (3) is caused about an axis of correction (Y-Y) radial to the axis of rotation (X-X) of the toroidal support itself, situated in substantially barycentric position relative to the segment (5) which is about to be laid. A perfect match is thereby assured of each strip-like segment (5) with the adjacent strip-like segments, even when the toroidal support (3) presents a crown area with curvilinear cross section profile.

Abstract: A system for manufacturing an elastomeric tire utilizing a separate formation of a package having a tire core shape and containing tire belts, plies and beads. The package is formed by a laying up of layers of pre-cure elastomer intradigitated with sections of porous fabric, where the fabric fibers are placed at desired crossing angles to one another, and the pre-cure elastomer layers are positioned therebetween as a sandwich, with the sandwich then cold rolled into the tire core shape. Inelastic hoop shaped beads are fitted to and encapsulated in the tire core side walls ends and, as required, an inelastic belt is fitted around the tire core tread area that is secured thereto as by cold rolling a layer of pre-cure elastomer thereover, completing the tire core package. The tire core package is fitted into a mold, preferably a spin casting mold, and is supported therein equidistant from the mold cavity walls to receive an elastomer sprayed therein as the mold is spun. During spinning, the exothermic heat of reaction of the sprayed elastomer constituents as is generated as they are mixed and sprayed into the mold, completes the cure of the pre-cure elastomer, providing a homogenous finished tire with the belts, plies and beads optimally positioned therein.

Abstract: A tire (20) comprises a bead core (22) of ferromagnetic material, for example steel wire, around which one or more windings (30a, 30b, . . . , 30n) of conducting wire are wound to form the secondary of an electricity generator of the induction type. The assembly of windings and bead core (22), together with the circuits using the electricity thus generated, is produced as a single unit to be incorporated, together with the bead filler (26), in a bead (28) of the tire, and of one or more magnets fixed with respect to the hub of the wheel or integral with the chassis of a vehicle comprising a wheel (18) fitted with the tire (20), which induce current in the windings. If the magnets are electromagnets (32) supplied with alternating current, the electricity generator operates both when the wheel (18) is rotating and when the wheel is stationary. On the other hand, if the magnets are permanent magnets (66) or electromagnets supplied with direct current, the electricity generator operates only if the wheel (18) is rotating.

Abstract: A body ply (12) comprising an elastomeric sheet (30) and a plurality of rows of reinforcement cords (32) embedded therein. The plurality of rows can comprise two parallel rows (32a, 32b) of reinforcement cords and the reinforcement cords in one row can be transversely staggered relative to the reinforcement cords in an adjacent row. To make the body ply (12), the reinforcement cords (32) are introduced into a die assembly (44) and rubber is extruded around and between the reinforcement cords. Existing equipment, namely an extrusion apparatus (40) conventionally used to manufacture steel belts or single layer body ply material, can be used to make the body ply material by providing an appropriate replacement insert (56) for its die assembly.
