ABSTRACT:
The inner surface of a green tire provided with an air-sealing liner, is cured or partially cured to produce a steam- and water-resistant surface, and the tire after such treatment is cured in a usual press without an air-bag or bladder.
One or more plies of a tire, usually the outer fabric plies, are partially cured before assembly in the tire, to insure that plies so located are cured, without over-curing inner and outer portions of the tire.
New tires are made by placing a carcass, whether green or partially cured, in a mold and extruding rubber over the outer surface of this carcass to fill the mold, and then giving the final cure to the resulting tire.
Tires are retreaded by applying ribbons of tread stock over the carcass prepared in any conventional manner, and then completing the cure without the use of a mold.
Retreaded tires are cured by placing a carcass prepared in any conventional manner, in a mold, extruding tread stock into the mold around the carcass, and the curing.
A tire, the inner surface of which is provided with a non-cured liner reinforced with a non-wicking fabric is cured without an air-bag or bladder.
Curing or partial curing may be effected by electron irradiation. Progressive irradiation is disclosed by which an object is repeatedly irradiated to attain a desired cure. Other methods of curing may be preferable in some operations.
