摘要： A method and apparatus for molding and curing a pneumatic tire in which the method comprises fixing in a symmetrical position with respect to the mid-circumferential plane of the mold the beads and part of the side walls of a tire which has been partially shaped, maintaining the profile of the tread band centered with respect to the plane, partially impressing a profile on the tread band by causing penetration of the radial sculptures of the mold in the band while pressure is within the tire, completing the profile by expanding the top portion of the tire by increasing the pressure within the tire and curing the tire. The apparatus includes a mold constituted by two continuous annular sections for contact with the sidewalls of the tire and a plurality of sectors disposed around the tread band capable of radial displacement and carrying radial sculptures corresponding to the cavities of the profile to be molded on the tread band and an elastic membrane capable of fitting within the tire and of exerting different pressures on the interior of the tire at different positions of the mold elements by the admission of compressed fluid inside the membrane. The assembled apparatus is perfectly centered with respect to the mid-circumferential plane of the tire. Attached to the annular sections and sectors are platens to cure the tire after it has had the profile impressed upon the tread band.

摘要： PROBLEM TO BE SOLVED: To prevent separation between adjacent blend layers and also prevent a corrosion phenomenon in a metal reinforcement or the like by applying an treatment for preventing the pressurized fluid from passing in the inner side of a tire itself on the inner surface of a green tire before introducing the pressurized fluid. SOLUTION: The inner surface of a tire 1 is treated before introducing the pressurized heated fluid in the inner side of the tire 1 itself. At least one primer layer 13 of a pre-vulcanized elastomer material is formed in the inner surface of the tire 1. The elastomer material is pre-vulcanized to the extent that penetration of the pressurized heated fluid inside the structure of the tire 1 is effectively prevented after introducing the tire 1 in vulcanizing molds 2 during the production process or the following tire 1. In order to achieve the sufficient pre- vulcanization of the primer layer 13 before introducing the tire 1 in the vulcanizing molds 2, a mixture of the pre-vulcanized elastomer material for forming a layer is prepared, and a cross-linking is formed at a relatively low temperature.

摘要： PROBLEM TO BE SOLVED: To fix a tire to a rim effectively and hold a bead fixedly between rim a butting surfaces, even when pressure does not exist inside of the tire owing to a tire blowout. SOLUTION: An air tube 3 shaped into a enclosed-pipe is defined by carcass plys 6, 11 formed from a code wound around a cross-sectional profile of the air tube so as to form a curvature along an extending distance in the circumferential direction. A ring-shaped fixing element 7 lies between the carcass plys 6, 11, and each element 7 is provided with a pointed primary portion 7a which defines a tire bead and incorporates a ring-shaped reinforcing insert 9. A rim 2, to which a tire 1 is attached, is provided with an operation abutting surface 16 at the tire bead in a side portion and provided with a cylindrical center positioning surface 17 certainly positioning the center of a tire to an axis of the wheel.

摘要： PROBLEM TO BE SOLVED: To produce various models at minimum costs by a method in which the number of tires of each system is divided into lots consisting of a specified number of tires, and the production of a specified lot of unvulcanized tires of a specified system and the production of a lot a system different from it are done alternately. SOLUTION: Tires of various systems are divided into lots in advance. Each lot is made to include the production of one mold per 24 hr. First, the lot of the first system is produced, and tools and a relative control condition are changed to produce the lot of the second system. The production is repeated similarly until a lot of each system is produced, and the production is started again from another lot of the first system. For that purpose, A constitutional element necessary for the produced tire is attached to a distribution device 212, and tools obtained from a receiving position 240 are arranged previously in a production machine 210. In a vulcanization treatment area 300, a mold for providing a prescribed design is attached to work the same unvulcanized tire.

摘要： PROBLEM TO BE SOLVED: To reduce the noise level and to improve the water discharging function by employing special arrangement, dimensions and a shape for grooves in the longitudinal direction and grooves in the transverse direction of a tire for automobiles. SOLUTION: In this tire for automobile wheels, the grooves 9 in the longitudinal direction of a tread band 3 and the grooves 10 in the transverse direction are inclined opposite to each other on both sides of the equatorial plane of the tire, and intersected portions form lags 6. The grooves 9 in the longitudinal direction have a part of an extended portion included in a contact area A of the tire. Inclined portions of the grooves 9 in the longitudinal direction are tapered at both ends and have blind hole shapes to form an end portion oriented in the circumferential direction. A tapered end portion oriented in the circumferential direction is shorter than the inclined portion.

摘要： PROBLEM TO BE SOLVED: To provide a method for molding/curing a tire for a vehicle wheel which can obtain desirable effects for a final product stably by a method in which the inner end fringe in the circumferential direction of a tire is substantially disengaged from a ring-shaped support simultaneously with the inflation of the tire and made freely movable to/from the support by a controlled method. SOLUTION: An unvulcanized tire 7 produced on a ring-shaped support 10 is enclosed in a vulcanization casting mold 2. After the inflation of the tire 7, steam or another pressurized fluids is supplied to a diffusion cavity 18 formed between the inner surface of the tire 7 and the outer surface of the support 10. The inflation of the tire 7 is corrected by the separation of a bead 7b in the axial direction from the support 10. In this way, the generation of excessive tension by codes forming a tire carcass structure is prevented. The inner surface of the tire 7 is coated with a preliminarily cured liner in advance to prevent the diffusion of water particles in an unvulcanized elastomer.

摘要： PROBLEM TO BE SOLVED: To provide a winter type tire with a tread pattern whose tread bands are especially suitable for traveling on a road covered with snow and/or ice, and its manufacturing method. SOLUTION: A tire especially designed for traveling on snow-covered road has a tread band 1 in a tread block 3. A first system and a second system of sipes 9 are formed in the block. Individual sipes are slanted in opposite direction in respect to a direction (n) perpendicular to a rolling surface of the treat bands 1. The sipes 9 extend along a curved extension part in recessed form to a grip end 10a with a sharp angle that is indicated by individual flexible parts 10 whose boundary is set by sipes themselves in the block 3. The peripheries of individual blocks 3 are partitioned by crosswise grooves 5 having first sides perpendicular to a rolling surface and second sides extending from the first side to the rolling surface itself, and lengthwise grooves.

摘要： PROBLEM TO BE SOLVED: To reduce a standard deviation between tires of different types as much as possible by continuously supplying a vulcanized material to an inlet of a final range, and maintaining a temperature and a viscosity value of a blend of an outlet of an initial range in a predetermined range. SOLUTION: A polymer material and various components from tanks 104 and 105 are continuously supplied to a transfer cooler 4 of a blend by a biaxial screw mixer 2 from a charging hopper 3. Further, not only the blend from the cooler 4 but also vulcanized components from tans 106 and 107 are continuously supplied directly from the hopper. At this time, a heating profile of the blend to be processed is controlled based on temperature and viscosity value at outlets C-C, A-A and B-B of the mixer 2 at two parts or more along the mixer 2. Thus, a standard deviation between the manufactured compounds is reduced, and its uniformity can be improved.
