ABSTRACT:
A method of creating an air barrier on both sides of an innerliner splice on the inside surface of a green tire when a bladder release lubricant is being applied thereto to prevent contamination of the splice. High pressure air is directed through air nozzles on both sides of the innerliner splice just prior to and during the application of the lubricant. A pressure sensor detects high or low air pressure during the creation of the air barriers to stop the spray of lubricant should either situation be detected.
