Abstract
Apparatus and methods for automatically spraying a mist of mold release into the confined space between a tire and an inflatable bladder in a tire molding machine so that the mold release covers the outer surface of the inflatable bladder and/or the interior surface of the tire and does not get onto the walls of the mold. In addition, bladder release is pre-sprayed onto the interior surface of the green tire prior to posititoning the green tire within the tire mold.
