Abstract

Apparatus and method for measuring adhesion capability in a tire liner, the apparatus including a film strip attaching to the tire liner and having a through opening and an attachment interface distanced from the opening; an adhesive backed cover member attaching to the film strip in covering relationship to the strip opening and a cover member surface portion establishing an adhesive bond with the tire liner through the film strip opening; means attached to the strip attachment interface for exerting a directional peeling force upon the strip sufficient to unitarily peel the film strip and the cover member from the tire liner; and means for measuring the directional peeling force.

Claims

1. Apparatus for measuring adhesion capability in a tire liner, characterized by:

a film strip having a through opening and an attachment interface distanced from the opening;

an adhesive backed cover member for attachment to the film strip in covering relationship to the strip opening;

means attached to the strip attachment interface for exerting a directional peeling force upon the strip; and

means for measuring the directional peeling force.

2. Apparatus according to claim 1 wherein the film strip opening is shaped and dimensioned to overlap at least part of a target region of a tire inner liner.

3. Apparatus according to claim 1 wherein the attachment interface comprises a through-hole.

4. Apparatus according to claim 1 wherein the cover member comprises a tape strip for attachment over the film strip and having an adhesive tape surface exposed through the film strip opening.

5. In combination a tire and apparatus for measuring adhesion capability of a tire inner liner characterized by:

the tire liner having a target surface region;

a film strip for attachment to the tire liner and having a through opening located for overlapping at least a portion of the tire liner target surface region and the film strip having an attachment interface distanced from the opening;

an adhesive backed cover member for attachment to the film strip in covering relationship to the strip opening and the cover member including a portion for establishing adhesive contact with at least of portion of the tire liner target surface region through the film strip opening;

means attached to the strip attachment interface for exerting a directional peeling force upon the strip sufficient to separate the cover member portion from the tire liner target surface region portion; and

means for measuring the directional peeling force.

6. Apparatus according to claim 5, wherein the film strip opening is shaped and dimensioned to overlap at least part of a target region of a tire inner liner.

7. Apparatus according to claim 5, wherein the attachment interface comprises a through-hole.

8. Apparatus according to claim 5, wherein the cover member comprises a tape strip for attachment over the film strip and having an adhesive tape surface portion exposed through the film strip opening.

9. Apparatus according to claim 5, wherein the tire liner target surface region is an annular surface extending about a sidewall portion of the tire liner.

10. A method for measuring adhesion capability in a tire liner, characterized by the steps:

a. positioning a film strip over a tire liner surface, the film strip having an opening disposed to overlap a liner target surface region and an attachment interface distanced from the film strip opening;

b. applying an adhesive backed tape to the film strip over the film strip opening and into an adhesive attachment with a portion of the tire liner target region located through the film strip opening;

c. engaging the film strip interface to unitarily peel the film strip and the tape from the liner surface; and

d. measuring the force required to effect the peeling of the film strip and tape from the liner surface.
