摘要： A method of producing a radial tire for a construction vehicle, the method enabling a vast reduction in facility costs. A first green tire is formed in a first step molding machine and then removed from it. After that, a vulcanizer bladder unit is installed on the tire. The tire is inflated by the vulcanizer bladder unit and then again placed in the first step molding machine with the vulcanizer bladder unit installed. After that, on the first step molding machine, belts and tread rubber are adhered to the outer periphery of the tire to form a completed green tire. Then the completed green tire, with the vulcanizer bladder unit, is assembled in a vulcanizing mold for vulcanization.

摘要： A method of highly efficiently producing pneumatic tires, wherein both bead portions (B) of a green tire (G) are supported by a pair of holders (24, 50) and opposite axial ends of a bladder (25) are tightly attached to the holders (24, 50), respectively. The holders (24, 50) are joined to each other and a fluid is supplied into the bladder (25), to preliminarily inflate the bladder (25) within the green tire (G). The green tire (G) is transferred into a vulcanizer, together with the holders (24, 50) and the preliminarily inflated bladder (25). A heat medium is supplied into the bladder (25), to vulcanize the green tire (G) and form a vulcanized tire (K). The preliminary inflation of the bladder (25) at a location outside of the vulcanizer eliminates or shortens the waiting time within the vulcanizer, thereby improving the overall work efficiency and productivity at a tire factory.

摘要： A cylindrical-shaped body is formed by mounting a carcass to the outer peripheral side of a film formed of a thermoplastic resin or a thermoplastic resin elastomer composition, a primary molded body is formed by fitting bead rings on opposite width direction ends of the cylindrical-shaped body, and the primary molded body is sucked on the inner peripheral surface of a transfer and holding mold. After a rigid inner mold is inserted into the body, suction is stopped and the body is transferred to the outer peripheral surface of the inner mold. Then, another tire member is stacked on the outer peripheral surface to mold a green tire. The tire, from which the inner mold was removed, is mounted inside a curing mold which is heated. The film is inflated and heated to vulcanize the tire, and bonded to the inner peripheral tire surface to form an inner layer.

摘要： A green tire is built on a forming drum and then transferred to a bead molding and pre-vulcanization station where each bead of the tire is molded by tightening it between two axially opposite clamping surfaces respectively carried by an axially external annular locating element and an axially internal annular locating element consisting of radially expandable circumferential sectors. The tightened beads can be pre-vulcanized through heat supply by means of electric resistors integrated into the axially external annular locating elements. The tire with the tightened and possibly pre-vulcanized beads is transferred to a molding cavity having an inner wall substantially conforming to the shape of an outer surface of the molded tire to carry out molding and complete vulcanization of the tire.

摘要： An apparatus for effectively heating a green tire generates heat to a metal member embedded therein using electromagnetic induction, to complete a heating formation of a green tire in a sufficiently short time. Particularly, in the thick portion of the green tire which is hard to heat, the efficiency of heat generation due to electromagnetic induction is increased by effectively concentrating a high frequency magnetic field on the metal member embedded therein. The apparatus for heating a green tire includes a local heating coil for forming a high frequency magnetic field along a portion of extending direction of a metal member, a high frequency power supply for supplying high frequency power to the local heating coil, and a mechanism for moving the local heating coil relatively in the extending direction of the metal member.

摘要： There is disclosed herein a method of manufacturing low aspect radial tires. The radial tires are mounted upon a bladder assembly during the time from the assembly of the tread reinforcing structure with the carcass until the vulcanization of the tire in a mold. Restrictor band material is wrapped around the tire to prevent circumferential growth of the tire beyond a predetermined diameter, so that the tire will not become too large to fit into the mold.

摘要： A green tyre (2) for bicycles is built, comprising at least one carcass ply (4) having axially opposite end flaps (4a) engaged with respective bead cores (5) and a tread band (6) applied in a radially outer position around said at least one carcass ply (4). The built tyre (2) removed from the building drum, is profiled so as to translate the tread band (6) in a radially outer direction with respect to the bead cores (5), so as to impart a cross-sectional convex profile to the tyre (2) in a radially outer direction. The profiled tire is engaged by means of a transfer member (31) comprising a gripping device (30) which holds it hanging and loads it into a vulcanisation mould (101) by axially positioning an axial centreline plane (M) of the green tyre at an axial reference (51) arranged at a predetermined height along a reference axis (K) of a central body (103) of the vulcanisation mould (101).
