A method for manufacturing a belt-shaped cord member by cutting a rubber topped fabric produced by covering a topping rubber on an interdigitated fabric formed by interweaving many warp textile cords and few wefts to a predetermined width, comprising; an interdigitated fabric forming step of arranging a cord having conductivity for every predetermined number of the many warp textile cords which is then interwoven with the weft yarn, a rubber topped fabric producing step of topping rubber on the front and back surfaces of the interdigitated fabric, and a cutting step of cutting the produced rubber topped fabric by every predetermined number of the textile cords, wherein, in the cutting step, the rubber topped fabric is cut along the textile cord in which a cord having conductivity is arranged, after the position of the textile cords is specified by energizing the rubber topped fabric.

A tire includes: an annular tire frame member; and a belt layer that is provided at an outer periphery of the tire frame member, wherein the belt layer includes a reinforcing cord spirally wound at intervals in a tire width direction, a resin layer that surrounds the reinforcing cord and integrally covers the reinforcing cord across an entire area of the reinforcing cord in the tire width direction, and a bonding layer that is bonded to one surface of the resin layer.

A method and a device for manufacturing a rubber coated cord, comprising:

a rubber coated cord including a preceding cord is manufactured by causing the preceding cord to pass through a preceding head while filling the preceding head with unvulcanized rubber extruded from a rubber extruder, and a rubber coated cord including a next cord is manufactured by setting a leading edge portion of the next cord in a state where the leading edge portion of the next cord has passed through the next head in advance, manufacturing a predetermined length of the rubber coated cord including the preceding cord, and subsequently causing the next cord including a leading edge portion side range bonded to a trailing edge portion of the rubber coated cord including the preceding cord to pass through the next head while switching from the preceding head to the next head.

A belt layer is provided at a tire radial direction (arrow R direction) outer side of a carcass. This belt layer is structured to include a reinforcing portion and a resin portion. The reinforcing portion of the belt is formed by reinforcing cords crossing, and surfaces of the resin cords are covered by the resin portion.

A tire includes a spiral belt layer and ring-shaped bands. The spiral belt layer is provided at the outer periphery side of a tire carcass member and is formed by a resin-coated cord wound in a helical shape. The bands are disposed at the tire diameter direction outer side of each of an end portion of the spiral belt layer at one side in the tire width direction and an end portion at the other side. Each band includes a belt-shaped member that is wound at least one full circumference in the tire circumference direction. The band is provided with an overlap portion that is specified with a larger number of layers of the belt-shaped member than other regions of the band in the circumference direction. The overlap portion is disposed at a circumference direction position that does not correspond with length direction end portions of the resin-coated cord.

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 shear band for a tire includes a first belt layer extending circumferentially around the tire, a second belt layer extending circumferentially around the tire, and a shear band coupon radially interposed between the first belt layer and the second belt layer. The shear band coupon includes a first reinforcing ply radially adjacent the first belt layer, a third reinforcing ply radially adjacent the second belt layer, and a second reinforcing ply radially interposed between the first reinforcing ply and the second reinforcing ply. The first reinforcing ply includes a first three dimensional layer enclosed by a first fabric layer. The second reinforcing ply includes a second three dimensional layer enclosed by a second fabric layer. The third reinforcing ply includes a third three dimensional layer enclosed by a third fabric layer.
