There is provided an apparatus configured to adhere a belt-shaped tire member onto a mold drum including: a feeding device including the belt-shaped tire member arranged so as to be capable of being fed and a transferring and adhering device configured to transfer the belt-shaped tire member from the feeding device side to the mold drum side and adhere the belt-shaped tire member onto the mold drum, wherein the transferring and adhering device includes: a transferring device configured to circulate between the feeding device side and the mold drum side and transfer the belt-shaped tire member sucked on the feeding device side to the mold drum side; and a separating unit configured to separate the transferred belt-shaped tire member on the mold drum side from the transferring device and adhere the belt-shaped tire member onto the mold drum.

Apparatus and method of adhering belt-shaped tire member

A sidewall rubber disposed outside of a carcass layer, reinforcing a portion between beads, in a widthwise direction of the tire is configured from a wide rubber ribbon having a width of 20 to 100 mm wound spirally along a circumferential direction of the tire outward of the tire such that the rubber ribbon is deviated radially outward of the tire.

Pneumatic tire and producing method of pneumatic tire

A carcass ply producing apparatus for producing a carcass ply constituting a carcass layer of a tire includes a supply head for supplying one or a plurality of ply cords, a head driving mechanism for reciprocating the supply head along a widthwise direction of the carcass ply, a sticking body having a sticking surface to which the ply cord supplied by the supply head is stuck, a sticking body driving mechanism for moving the sticking surface of the sticking body along a longitudinal direction of the carcass ply, and a moving amount controlling mechanism capable of controlling a moving amount of the sticking surface with respect to a moving amount of the supply head. When the ply cord is supplied along the widthwise direction of the carcass ply, a disposition angle of the ply cord with respect to the longitudinal direction can be changed.
