Abstract
A multi layered tire former bladder and a method for making the bladder is described. The multi layered bladder includes a elastomeric bladder having an outer surface and an inner surface; a release coating on the outer surface of the bladder; and at least two fabric reinforcing plies which include a first outer ply embedded in the bladder below the outer surface and an inner surface fabric ply at the inner surface of the bladder. In the method of making the bladder an air dried release coating is applied to the outer elastomeric surface of the bladder.
