A stitcher device presses a carcass ply to be pressure-bonded to a rubber member after that the carcass ply is wound around an outer periphery of a building drum movable along a drum guide path via a rubber member. The stitcher device includes an annular frame that is able to surround the outer periphery of the building drum by inserting the building drum thereinto, and a pressure-bonding device provided in the annular frame so as to be able to press the carcass ply from its outer periphery and pressure-bond the carcass ply to the rubber member. The annular frame is provided so as to be openable and closable by being divided into a plurality of parts in a peripheral direction.

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 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 cutting out a sheet-like belt for one full circle of tire by cutting a master roll diagonally with respect to a longitudinal direction between a master roll table 10 and a belt table 14, moving the belt table 14 carrying the cut-out sheet-like belt to a winding position of the sheet-like belt, winding the sheet-like belt around a winding cylinder 50 at the winding position, and unwinding the sheet-like belt from the winding cylinder 50 in a place facing a molding drum 64 and forming a cylindrical belt by winding the sheet-like belt around the molding drum 64.

A method of forming a belt structure for a tire includes providing a drum having a center section. A first drum edge is near a first edge of the center section and a second drum edge is near a second edge of the center section. A first end surface extends from the center section first edge to the drum first edge and a second end surface extends from the center section second edge to the drum second edge, and a radius of each end surface is smaller than the center section radius. A rubber strip reinforced by a plurality of cords includes an outer edge and an inner edge. The strip is wound about the drum, turning from a first winding angle to a second winding angle on an end surface to reduce the tension and length differential between cords at the outer edge and inner edge of the strip.

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 pneumatic tire for resonance noise reduction, which includes a plurality of resonance noise-reducing members that are disposed along the circumferential direction of the inner liner of a tire, and are formed to protrude from the inner liner so as to reduce the interference of the resonance noises generated inside the tire. The resonance noise-reducing members are formed at an irregular interval of disposition along the circumferential direction of the inner liner.

A manufacturing device includes a belt table situated adjacent to a master roll table; a hand feeding the master roll from the master roll table to the belt table; and a cutting device cutting the master roll between the master roll table and the belt table, wherein the hand includes a first hand which keeps holding a front part of the master roll in a feeding direction of the master roll from start to end of feeding of the master roll and a second hand which holds a rear part trailing the front part in the feeding direction

A pneumatic tire (1) is provided with a cylindrical annular structure (10) that is disposed around the rotational axis and that has an outer surface and an inner surface, a carcass portion (12) at least a part of which is disposed on an outer side of the annular structure in a direction parallel to the rotational axis, the carcass portion (12) having a cord covered by rubber, a rubber layer (11) at least a part of which is disposed so as to face the outer surface of the annular structure, the rubber layer (11) including a tread portion, and a fiber (2) disposed between the annular structure and the rubber layer so as to suppress generation of a gas space between the annular structure and the rubber layer.
