Abstract: The herein described invention relates to a preparing of tires where a part of the tire is cured by exposure to electron irradiation or other means of radiation which have the same curing effect on the part. The irradiation is effected in a continuous operation in which the source of radiation and said part are moved continuously relatively to one another.

Abstract: Strands of steel bead wire or the like are individually surrounded with rubber and the rubber is then partially cured sufficiently by irradiation so that the rubber remains moldably plastic and the final cure will completely cure the rubber. Each bead core when completed is often enclosed in fabric. The completed bead assembly is incorporated in the carcass of a tire. When the tires, including the carcass, tread, etc., are cured, the rubber in the beads is completely cured and the beads are securely bonded to the balance of the tire.

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 then curing.

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.
