A winding method includes: attracting a sheet-like belt 8b onto a table 14 by multiple attracting means 15 lined up in a longitudinal direction of the sheet-like belt 8b; and winding the sheet-like belt 8b around a winding cylinder 50 by moving the winding cylinder 50 in the longitudinal direction of the sheet-like belt 8b while rotating the winding cylinder 50 above the sheet-like belt 8b and by cancelling attraction by the attracting means 15 one after another from attracting means 15 to which the winding cylinder 50 has moved.

A manufacturing method includes feeding a master roll 8a from a master roll table 10 to a belt table 14, and cutting the master roll 8a between the master roll table 10 and the belt table 14. In the step of feeding the master roll 8a from the master roll table 10 to the belt table 14, the master roll 8a is fed by holding a front part of the master roll 8a by a first hand 30 and a rear part of the master roll 8a by a second hand 40, and the front part of the master roll 8a is continuously held by the first hand 30 from start to end of the feeding.

A manufacturing method for manufacturing a sheet-like belt 8b from a master roll first and then forming a cylindrical belt by winding the sheet-like belt 8b around a molding drum includes measuring a length of the sheet-like belt 8b, and making a pass of fail determination as to the length of the sheet-like belt 8b. The sheet-like belt 8b is wound around a winding cylinder 50 and transported to a place for lamination to the molding drum only when a pass determination is made in the step of making a pass or fail determination as to the length of the sheet-like belt 8b.

A manufacturing method includes: cutting out a sheet-like belt 8b by cutting a master roll 8a between a master roll table 10 and a belt table 14; moving the belt table 14 carrying the cut-out sheet-like belt 8b to a winding position of the sheet-like belt 8b; and winding the sheet-like belt 8b around a winding cylinder 50 at the winding position. The master roll 8a is fixed onto the belt table 14 by attraction when the master roll 8a is cut between the master roll table 10 and the belt table 14 and the belt table 14 is moved to the winding position of the sheet-like belt 8b while keeping the cut-out sheet-like belt 8b fixed onto the belt table 14 by attraction.

A tire-wheel assembly includes a run-flat support member disposed on an inner side of a tread portion of a pneumatic tire, wherein the run-flat support member is made from a foamed body and has a height or greater of a cavity height of the pneumatic tire. When an internal pressure of the pneumatic tire is higher than a predetermined air pressure, the run-flat support member does not come into contact with a rim of the wheel, a side portion of the pneumatic tire, or an inner circumferential surface of a bead portion When an internal pressure of the pneumatic tire is equal to or lower than a predetermined air pressure, an inner side of the run-flat support member in a tire radial direction comes into contact with an outer circumference of the rim of the wheel and/or the inner circumferential surface of the bead portion of the pneumatic tire.

Methods for treating a cured inner liner as well as treated, cured inner liners resulting from such methods are disclosed. Also disclosed are tires containing the treated inner liners. The methods include treatment of the lower surface of inner liner surface with a rubber-containing liquid to produce a rubber-containing film thereupon.

A tire-wheel assembly includes a run-flat support member disposed on a rim within a cavity portion of a pneumatic tire and including a support surface formed on an outer circumference; the run-flat support member being a bladder comprising a foamed body therein and being disposed in an annular manner around an outer circumference of the rim.

To control compressed air to a prescribed pressure without using a relief valve and a chamber and to suppress deviation of the pressure. A compressor device 2 of a puncture repair kit 1 has a pressure gauge 6. The pressure gauge 6 has a tubular body portion 18 provided in a front end portion with a communicating hole 21 communicating with a surge chamber 12B, a piston 19 movable within the tubular body portion 18 in the longitudinal direction by the compressed air from the communicating hole 21, and a spring 20 biasing the piston 19 toward the front end and changing its displacement according to the magnitude of the pressure of the compressed air. An exhaust port 25 is formed on the peripheral wall of the tubular body portion 18. The exhaust port 25 releases the compressed air when a seal ring 23 of the piston 19 exceeds the exhaust port 25.

A method and system for cleaning the inner surface of a tire, comprising the steps of: emitting a laser beam that is directed against the inner surface using at least an emitter device; performing deeper cleaning within at least a first annular zone of the inner surface in applying, using at least the laser beam, to the first annular zone a first surface energy density; and performing less thorough cleaning within at least a second annular zone of the inner surface by applying, using at least the laser beam to the second annular zone a second surface energy density that is lower than the first surface energy density.

A method for predicting a pressing force of a bead portion of a tire having a bead core in the bead portion, comprises a step of predicting the pressing force of the bead portion when the tire is fitted onto a rim of a wheel by using a numeric expression including at least the inner diameter of the bead core, the diameter of the rim, and the thickness inward in the tire radial direction from the bead core.
