Method for sealing porosity leaks in pneumatic tires
First Claim
1. A method for sealing porosity openings in a pneumatic tire having an interior chamber which comprises the steps ofintroducing into the interior tire chamber an aqueous sealing solution containing a butyl latex emulsion and natural fibers;
- inflating the tire;
rotating the inflated tire and forming a film of the sealing solution over the interior chamber;
flowing portions of the sealing solution into the porosity openings;
rotating the tire over a surface and creating frictional heat; and
utilizing the frictional heat to dry the portions of the sealing solution within the porosity openings and effecting sealing closure of the said openings.

Abstract
The method of sealing microscopic holes formed in tires and similar articles during the manufacturing process including the steps of reducing the pressure within the tire to substantially atmospheric pressure, introducing an emulsion of butyl latex combined with natural fibers into the interior void defined by the tire, inflating the tire with air to super atmospheric pressure, rotating the tire to contact the microscopic openings with portions of the emulsion and then solidifying the portions of the emulsion within the openings to effect closure.
