Tire manufacturing method
A tire manufacturing method includes: a step of arranging rubber inside a spring antenna of an electronic component having a communication function, a step of interposing by rubber sheets the electronic component having the spring antenna into which rubber was arranged, and a setting step of arranging the electronic component interposed by rubber sheets in a tire.
1. A tire manufacturing method comprising:
preparing an electronic component which includes a coil-shaped spring antenna that transmits or receives wireless signals,
filling rubber only inside the coil-shaped spring antenna of the electronic component, wherein air is not left in the spring antenna between the antenna and the rubber filled inside the antenna;
interposing, between two rubber sheets, the electronic component having the coil-shaped spring antenna into which the rubber was filled; and
setting the electronic component interposed between the two rubber sheets in a tire.
2. The tire manufacturing method according to claim 1 , wherein the filling step includes filling the rubber inside the coil-shaped spring antenna until the inside of the coil-shaped spring antenna is completely embedded in the rubber so that air is not left in the spring antenna between the antenna and the rubber.
3. The tire manufacturing method according to claim 2 , wherein the tire further includes a carcass ply and a side-wall rubber which is provided to an outer side in a tire-width direction of the carcass ply, and
wherein the rubber sheets are configured from rubber having a higher modulus than the side-wall rubber.
4. A manufacturing method of an electronic component which is interposed between two rubber sheets and includes a coil-shaped spring antenna that transmits and receives wireless signals, and an RFID chip to which the coil-shaped spring antenna is connected, and to be set in a tire,
the method comprises filling, in the electronic component which includes the coil-shaped spring antenna and the RFID chip, rubber only inside the coil-shaped spring antenna of the electronic component;
and
interposing the electronic component which includes the coil-shaped spring antenna in which the rubber was filled and the RFID chip between the two rubber sheets; wherein
air is not left in the coil-shaped spring antenna between the antenna and the rubber filled inside the antenna.
5. A tire manufacturing method comprising:
preparing an electronic component which includes a coil-shaped spring antenna that transmits or receives wireless signals,
filling rubber only inside the coil-shaped spring antenna of the electronic component;
interposing, between two rubber sheets, the electronic component having the coil-shaped spring antenna into which the rubber was filled, wherein
air is not left in the spring antenna among the antenna, the rubber filled inside the antenna, and the rubber sheets; and
setting the electronic component interposed between the two rubber sheets in a tire.
6. The tire manufacturing method according to claim 5 , wherein the filling step includes filling the rubber inside the coil-shaped spring antenna until the inside of the coil-shaped spring antenna is completely embedded in the rubber so that air is not left in the spring antenna between the antenna and the rubber.
7. The tire manufacturing method according to claim 6 , wherein the tire further includes a carcass ply and a side-wall rubber which is provided to an outer side in a tire-width direction of the carcass ply, and
wherein the rubber sheets are configured from rubber having a higher modulus than the side-wall rubber.
