The current embodiments provide a system for determining a parameter of a tire component. The system may have a background surface, a first measurement device configured to measure a dimension with respect to the reference surface and a support surface located at least partially between the first measurement device and the reference surface, where the support surface is configured to support the tire component. The parameter may correspond to the dimension on the background surface.

An apparatus for removing flash from a tire includes a laser sensor which, while the tire is rotating, can be moved along the outer contour of the shoulders and tread area of a tire to detect the contour of the tire. A first sanding assembly removes the flash from the tread area, while the tire is not rotating, by moving horizontally and vertically in accordance with the detected contour of the tread area. A second sanding assembly removes the flash from the shoulder area, while the tire is rotating, by moving horizontally, vertically, and pivotally in accordance with the detected contour of the shoulder area.

The laminate according to the present invention includes a thermoplastic resin film-containing layer and a rubber layer, in which the rubber layer contains a modified diene polymer, and the rubber layer has a dynamic storage modulus E′ at −20° C. of 1.0×10.sup.5 to 1.0×10.sup.8 Pa. This laminate can improve the resistance to the fractures and the cracks of the inner liner.

Methods for treating the surface of a cured inner liner are disclosed. By use of these methods a treated, cured inner liner is produced which has a lower surface with increased adherability to other materials (e.g., adhesives). Treated, cured inner liners resulting from such methods as well as tires containing the treated inner liners.

A method for manufacturing a pneumatic tire includes: a step of winding carcass plies around a molding drum to mold a carcass, wherein the carcass has a joint portion in which ends of each of the carcass plies in a tire circumferential direction are overlapped with each other, the method further includes a step of pasting a rubber tape that covers at least a part of the joint portion after winding the carcass ply, and the rubber tape has: a central portion pasted to an outside of the joint portion and extending with a constant thickness along the tire circumferential direction; and tapered portions individually extending from both ends of the central portion in the tire circumferential direction along the tire circumferential direction while reducing a thickness of each of the tapered portions, and having tip ends with an angle of 45 degrees or less.

Methods for treating the surface of a cured inner liner are disclosed. By use of these methods a treated, cured inner liner is produced which has a lower surface with increased adherability to other materials (e.g., adhesives). Treated, cured inner liners resulting from such methods as well as tires containing the treated inner liners.

In a pneumatic tire production method including a step of overlapping end portions of a sheet laminate and vulcanization-molding the tire, the sheet laminate being obtained by layering an elastomer layer and a sheet of a thermoplastic resin composition containing a thermoplastic resin or a blend of a thermoplastic resin and an elastomer, after the end portions of the sheet laminate are overlapped, the overlapped portion of the sheet laminate is compression-bonded at a temperature of not less than a glass transition temperature Tg of the thermoplastic resin and not greater than 120° C.

A post-cure inflation machine for processing a tire may include a tire holder shaft. The tire holder shaft may include a chuck to secure the tire to the tire holder shaft. A hollow passage may be defined in the tire holder shaft. A spray nozzle may be connected to a spray shaft that is telescopically disposed in the hollow passage of the tire holder shaft. The spray nozzle may extend to spray an air barrier material onto the tire.

Method and application unit (3) for applying a sound-absorbing material (2) to an inner cavity of a pneumatic tyre (1) using a strip (4) of sound-absorbing material (2) provided on one side with an adhesive layer (6) covered with a protective lining (7). The following steps are provided: attaching an initial part of the protective lining (7) to a recovery drum (26); partially winding the strip of sound-absorbing material onto the applicator roller (24); pressing, by means of the applicator roller (24), the strip (4) of sound-absorbing material (2) against the inner cavity of the pneumatic tyre (1) whilst the pneumatic tyre (1) is caused to rotate; and rotating the recovery drum (26) synchronously with the pneumatic tyre (1), such as to wind the protective lining (7) around the recovery drum (26), step-by-step, as the protective lining (7) is separated from the strip (4) of sound-absorbing material (2).

Provided is an attaching device and a method for attaching a band-like member to a tire inner surface. A holder that holds the band-like member in a wound state and a paddle are disposed in an inner portion of a tire, and a dispensed portion is pressure-bonded to the inner surface by repeatedly performing: a bonding operation in which a predetermined length dispensed from the band-like member in a wound state toward the inner surface is pressed, by moving the paddle close to the inner surface with no relative rotation of the tire in the circumferential direction with respect to the holder, and is pressure-bonded to the inner surface and a dispensing operation in which, after the bonding operation, the paddle is moved away from the inner surface, and together with relatively rotating the tire in the circumferential direction, a new dispensed portion is formed.
