Abstract

A method for preparing an innerliner of a pneumatic tire and adhering an electronic monitoring device to the innerliner includes the step of providing a patch having a cover and a layer of uncured rubber. The patch is placed at a selected area of the innerliner of a green tire before the green tire is cured. At least a portion of the patch is removed after the tire is cured to provide a prepared area at the selected area of the tire. The electronic monitoring device is then adhered to the prepared area.

Claims

1. A method for preparing an area on an innerliner of a pneumatic tire for the connection of an electronic monitoring device thereto, the method comprising the steps of:

(A) selecting an area of the innerliner of a green tire to be prepared;

(B) placing a patch on the innerliner at the selected area;

the patch having a first surface area facing the innerliner;

(C) curing the green tire whereby the patch provides the prepared area on the innerliner at the selected area; and

(D) pressing the entire first surface area of the patch against the innerliner during step (C) to texturize the selected area.

11. The method of claim 1, wherein step (C) includes the step of pressing the patch against the innerliner of the tire with the expandable bladder used during the curing process.

12. The method of claim 1, wherein step (A) includes the step of selecting an area of the innerliner adjacent the bead ring of the tire.

2. A method for preparing an area on an innerliner of a pneumatic tire for the connection of an electronic monitoring device thereto, the method comprising the steps of:

(A) selecting an area of the innerliner of a green tire to be prepared;

(B) placing a patch on the innerliner at the selected area;

(C) curing the green tire whereby the patch provides the prepared area on the innerliner at the selected area; and

(D) providing the patch with a layer of cured rubber and a layer of uncured rubber.

3. The method of claim 2, wherein step (B) includes the step of connecting the layer of uncured rubber to the innerliner.

4. The method of claim 3, further comprising the steps of providing the patch with a release cover over the layer of uncured rubber and removing the release cover of the patch prior to placing the patch on the innerliner.

5. The method of claim 3, wherein the step of placing the patch on the innerliner further includes the step of stitching the patch to the innerliner.

6. A method for preparing an area on an innerliner of a pneumatic tire for the connection of an electronic monitoring device thereto, the method comprising the steps of:

(A) selecting an area of the innerliner of a green tire to be prepared;

(B) placing a patch on the innerliner at the selected area;

(C) curing the green tire whereby the patch provides the prepared area on the innerliner at the selected area; and

(D) removing at least a portion of the patch after the step of curing the green tire.

7. The method of claim 6, wherein the step of placing the patch on the innerliner further includes the steps of providing a patch having a cover and a layer of uncured rubber and connecting the layer of uncured rubber to the innerliner.

8. The method of claim 7, wherein step (D) includes the step of removing the cover.

9. The method of claim 6, wherein step (D) texturizes the surface of the innerliner.

10. The method of claim 6, wherein step (D) includes the steps of depositing a frame of rubber on the surface of the innerliner and texturizing the surface of the innerliner inside the frame.

14. The method of claim 6, wherein step (D) includes the step of depositing a layer of rubber on the innerliner.

13. A method for preparing an area on an innerliner of a pneumatic tire for the connection of an electronic monitoring device thereto, the method comprising the steps of:

(A) selecting an area of the innerliner of a green tire to be prepared;

(B) placing a patch on the innerliner at the selected area;

(C) curing the green tire whereby the patch provides the prepared area on the innerliner at the selected area; and

(D) providing a patch having a frame of uncured rubber and a layer of cured rubber.

23. The method of claim 13, further comprising the step of removing the layer of cured rubber after the step of curing the green tire.

24. The method of claim 23, further comprising the step of providing a layer of cure material between the layer of uncured rubber and the layer of cured rubber.

25. The method of claim 24, further comprising the step of pressing the cure material against the innerliner through the frame of uncured rubber during step (C).

15. A method for preparing an area on an innerliner of a pneumatic tire and adhering an electronic monitoring device to the innerliner at the prepared area, the method comprising the steps of:

(A) placing a patch on the innerliner of a green tire at a selected location;

(B) curing the green tire;

(C) removing at least a portion of the patch to provide a prepared area at the selected location; and

(D) adhering an electronic monitoring device to the prepared area.

16. The method of claim 15, wherein step (C) includes the step of depositing rubber on the innerliner of the tire.

17. The method of claim 16, further comprising the step of providing an attachment patch connected to the electronic monitoring device, the attachment patch having a layer of uncured rubber.

18. The method of claim 17, further comprising the step of placing activator fluid on the rubber that was deposited on the innerliner and the uncured rubber of the attachment patch prior to connecting the electronic monitoring device to the innerliner.

19. The method of claim 17, further comprising the step of pressing the uncured rubber of the attachment patch against the rubber deposited on the innerliner of the tire and curing the two layers together with heat and pressure.

20. A method for preparing an area on an innerliner of a pneumatic tire and adhering an electronic monitoring device to the prepared area of the innerliner, the method comprising the steps of:

(A) placing a patch on the innerliner of a green tire at a selected location, the patch having a layer of uncured rubber contacting the innerliner, a cover, and a layer of cure material between the layers of uncured rubber and cover;

(B) curing the green tire whereby the layer of uncured rubber of the patch cures to the innerliner of the tire;

(C) removing the cover and cure material of the patch to provide a prepared area at the selected location;

(D) providing an attachment patch connected to the electronic monitoring device, the attachment patch having a layer of uncured rubber; and

(E) curing the uncured layer of rubber of the attachment patch to the prepared area of the innerliner.

21. The method of claim 20, wherein step (E) is achieved by chemically curing the two layers together.

22. The method of claim 20, wherein step (E) is achieved with heat and pressure.

26. A method for preparing an area on an innerliner of a pneumatic tire for the connection of an electronic monitoring device thereto, the method comprising the steps of:

(A) selecting an area of the innerliner of a green tire to be prepared;

(B) placing a patch on the innerliner at the selected area;

the patch having a first portion and a second portion;

(C) curing the green tire after the patch is positioned;

(D) depositing the first portion of the patch on the innerliner; and

(E) removing the second portion of the patch after step (C).

27. The method of claim 26, further comprising the step of attaching an electronic monitoring device to the first portion of the patch.
