ABSTRACT:
An apparatus for curing a tapered airsleeve has a bladder curing chamber into which a rigid tapered sleeve cartridge is inserted to form the airsleeve thereon. The bladder curing chamber is formed by a rigid bladder support tube positioned between upper and lower plates and joined by strain rods. A straight cylindrical bladder is positioned within the bladder support tube and the ends are sealed by flipping them from the inside of the bladder support tube 180.degree. over each end of the tube for sealing the curing chamber. The hollow tapered sleeve mold or cartridge is inserted into the bladder curing chamber and will be dimensionally similar to the airsleeve to be molded therein. A preshaped uncured green sleeve is positioned over the tapered sleeve cartridge before inserting it into the curing chamber. The straight cylindrical bladder is inflated and expands radially outwardly causing the uncured sleeve to conform against the tapered sleeve cartridge. A mixture of steam and air enters the interior of the support tube through an inlet port for expanding the bladder toward the sleeve cartridge, and together with a heated fluid injected into the hollow interior of the cartridge, cures the tapered sleeve.
