Abstract

The present invention is tag connected to an inner surface of a tire and the method of attaching a tag to the inner surface of a tire. Methods of mounting a tag on an inner surface of a tire include coating a tag or a premask film with a pressure sensitive adhesive on a side and adhering that side of the tag or premask to the inner surface of a tire. With the premask film, the tag is adhered to adhesive on the premask, normally after a release liner is removed. Similarly, direct mount of a tag with a pressure sensitive adhesive, the tire is cured after the tag is mounted, which allows the pressure sensitive adhesive on the tag to cure into the tire. The tire is ideally cured after attachment of the tag or premask film so the pressure sensitive adhesive strongly bonds to the inner surface of the tire.

Claims

1. A method of mounting a tag to an inner surface of a tire including the steps of:

obtaining materials to be made into a tire;

making a premask with a pressure sensitive adhesive on a first side of the premask;

cutting the premask in a shape that is compatible with the tag to be mounted;

adhering the first side of the premask to a surface that will be the inner surface of the tire;

curing the tire after the pressure sensitive adhesive is adhered to the inner surface; and

mounting the tag on the premask.

2. The method of claim 1 including an additional step of coating the tag with a complementary adhesive and wherein the step of mounting the tag on the premask includes mating the premask with the complementary adhesive of the tag and then applying pressure to the tag, wherein the premask will securely bond with the complementary adhesive of the tag so that the tag is securely mounted to the inner surface of the tire.

3. The method of claim 1 wherein the pressure sensitive adhesive is a rubber based adhesive.

4. The method of claim 1 wherein the pressure sensitive adhesive is a modified acrylic pressure sensitive adhesive including a grafted polymer.

5. The method of claim 1 including the additional steps of:

applying the pressure sensitive adhesive to a second side of the premask;

applying a release liner over the pressure sensitive adhesive on the second side; and

removing the release liner before the tag is mounted on the premask.

6. The method of claim 5 including an additional step of coating the tag with a complementary adhesive and wherein the step of mounting the tag on the premask includes mating the pressure sensitive adhesive of the premask with the complementary adhesive of the tag and then applying pressure to the tag, wherein the pressure sensitive adhesive of the second side of the premask will securely bond with the complementary adhesive of the tag so that the tag is securely mounted to the inner surface of the tire.

7. The method of claim 1 wherein the step of cutting the premask includes cutting the premask in a shape slightly larger than the tag to be mounted.

8. The method of claim 1 wherein the tag is a RFID tag.

9. The method of claim 1 wherein the tag is less than five mils thick.

10. The method of claim 1 wherein the tag includes the antenna and electrical contacts, and comprises an additional step of applying a chip-interposer to the tag.

11. The method of claim 1 wherein the premask has a substrate film that is less than two mils thick.

12. A method of mounting a tag directly on an inner surface of a tire comprising the steps of:

coating the tag with a pressure sensitive adhesive on a side;

attaching the adhesive-coated side of the tag to the inner surface of the uncured tire;

curing the tire with the tag attached to allow the pressure sensitive adhesive to cure into the tire.

13. The method of claim 12 wherein the pressure sensitive adhesive is a rubber based adhesive.

14. The method of claim 12 wherein the pressure sensitive adhesive is a modified acrylic based pressure sensitive adhesive.

15. The method of claim 12 wherein the tag is a RFID tag.

16. The method of claim 12 wherein the tag is less than 50 mils thick.

17. The method of claim 12 wherein the tag includes the antenna and electrical contacts, and comprises an additional step of applying a chip-interposer to the tag.

18. The method of claim 12 wherein the tag includes a polyester film less than two mils thick.
