Apparatus and method for testing tire liner surface adhesion capability
First Claim
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.

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.

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. - View Dependent Claims (6, 7, 8, 9)

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.
