The present invention relates to a roll over can drive apparatus of tire building machine supporting a bladder turning up a green tire semi-finished product on the molding drum when the bladders are expanded in the green tire molding process, and more specifically, to a roll over can of the tire building machine in which an operation cycle time and failure rate are reduced from a simplified structure. For this, the present invention discloses a roll over can drive device of a tire molding machine comprising: a bladder which supplies air to an interior of a various semi-finished products located on a forming drum and turns up the semi-finished products which located on a bead outside, and a roll over can which pushes the bladder to build a green tire, wherein the roll over can rotates on an axis of rotation of a supporting frame by a cylinder, and wherein the cylinder being connected to a support of the roll over can is mounted via a hinge axis to a top of the support frame.


A tire equipped with a sensor patch includes a sensor module and a sensor patch. The sensor patch is formed integrally with the inner liner of the tire by being vulcanized into the inner circumferential surface, and an accommodation space is formed in a region so that the sensor module can be fixed therein. A sensor patch is integrated with the inner liner without damaging the inner liner, and thus the sensor patch can be strongly bound to the tire. Furthermore, since the sensor patch is formed to have a thickness smaller than the thickness of the inner liner, when the sensor patch is vulcanized into the inner liner, the pressure of the bladder being exerted locally non-uniformly on the inner liner can be prevented.

A pneumatic tire and a method of fabricating a pneumatic tire are disclosed herein. The pneumatic tire includes a tread (10), sidewalls (20), and a carcass (103) including at least one carcass ply. One or more bead wire codes (105, 108) formed by stacking and arranging bead wires in a plurality of layers are formed on one or both sides of the carcass ply. One or more bead filler films (106, 107) are placed between the bead wire codes (105, 108). An end of the carcass ply (103) is wrapped around at least one bead wire code (105, 108). The wrap-around end (Tu) of the carcass ply (103) is disposed between neighboring bead wire codes (105) and (108) or beside the axially outermost bead wire code.

A pneumatic tire is disclosed herein. The pneumatic tire includes a carcass composed of one or more carcass plies that extend to span a tread, sidewalls, and bead parts. Ring bead sheet cords having a predetermined longitudinal length are disposed on both sides of each end of the carcass. Each bead part-side end of the carcass is interposed between the ring bead sheet cords. The ring bead sheet cords are each formed in a closed ring shape having no disconnection along a circumferential direction of the tire. Spaces between the ring bead sheet cords and between the carcass and ring bead sheet cords are filled with a rubber mixture.
