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 with or without an air-bag or bladder.
One or more tread layers or outer fabric plies, are partially cured before assembly in the tire, so as to shorten the curing time of the tire in the mold and thereby create substantial savings.
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 then curing.
A tire, the inner surface of which is provided with a non-cured liner reinforced with a non-wicking fabric is cured with or without an air-bag or bladder.
Curing or partial curing may be effected by electron irradiation or other irradiation which changes the molecular structure of the rubber. Progressive irradiation is disclosed by which an object is repeatedly irradiated to attain a desired cure. Shielding of one or more portions of a green tire or tire element is disclosed to prevent the irradiation from curing the shielded rubber. Other methods of curing may be preferable in some operations.
