Tires, etc.

The method of making a liner for a pneumatic tire which tire is to be cured by steam and/or hot water, which liner is composed of a plurality of layers, which method comprises curing or partially curing at least a portion of only one layer by irradiation which rearranges the molecular structure of the rubber therein, which portion is substantially coextensive with the other layers and laminating said layers while providing the outer and inner surfaces of the liner with rubber curable by the process used in curing the tire.

The method of making a liner for a pneumatic tire which liner includes an inner layer of a butyl rubber which is adapted to face toward subsequent tire-inflating fluid, the outer layer of the liner being adapted to contact the carcass of the tire and being composed of a rubber curable by irradiation which rearranges the molecular structure thereof, which method comprises curing by such irradiation the inner portion of said outer layer and laminating to the layer of rubber curable by irradiation a layer of a butyl rubber which forms the inner layer of the liner.

The method of making a liner for a pneumatic tire which liner is composed of a plurality of layers which method comprises curing or partially curing at least a portion of one layer by irradaition which rearranges the molecular structure of the rubber therein, which portion is substantially coextensive with the layer, and forming the inner surface of the liner which is the surface which is adapted to face toward subsequent tire-inflating fluid, by laminating another layer to said one layer without completely curing the outer surface of the liner which surface is adapted to contact the carcass.

The method of making a liner for a pneumatic tire which liner for a pneumatic tire which liner is composed of a plurality of layers and includes an inner layer of a butyl rubber which layer is adapted to face toward subsequent tire-inflating fluid, which method comprises curing or partially curing at least a portion of one layer by irradiation which rearranges the molecular structure thereof, which portion is substantially coextensive with the layer, and laminating the layers.

The method of making a liner for a pneumatic tire which liner is composed of a plurality of layers which method comprises curing or only partially curing at least a portion of only one layer other than the inner and outer surfaces of the liner by irradiation which rearranges the molecular structure of the layer, and laminating the layers.

The method of making a liner for a pneumatic tire which liner is composed of a plurality of layers, which method comprises laminating said layers and providing one layer composed of a rubber which is not curable by electron irradiation and a layer of other rubber which can be so cured, one surface of said latter layer forming the outer surface of the liner which is adapted to contact the carcass of the tire, and without completely curing said surface, curing or partially curing said rubber curable by irradiation which rearranges the molecular structure of the rubber.

The method of making a liner for a pneumatic tire, which liner is composed of a plurality of layers, which method comprises curing or partially curing at least a portion of the liner by irradiation which rearranges the molecular structure thereof without curing the inner layer which is adapted to face toward subsequent tire-inflating fluid, which portion is substantially coextensive with the layer, and without completely curing the outer surface of the liner which is opposite said layer, and laminating the layers.

The process of producing a laminated liner for a pneumatic tire which tire is to be cured in a conventional manner, which lamination comprises a first rubber layer which can be cured by electron irradiation and a second rubber layer which forms the inner surface of the liner which is the surface which is adapted to face toward subsequent tire-inflating fluid and which cannot be so cured but is curable by the method of curing the tire, which process comprises curing or partially curing the first layer by irradiation which rearranges the molecular structure of the layer, and laminating the layers, all without completely curing the outer surface of the liner which is adapted to contact the carcass of the tire.

The method of making a liner for a pneumatic tire, which liner is composed of a plurality of layers, which method comprises curing or partially curing at least a portion of only one layer of the liner by irradiation which rearranges the molecular structure of the layer and laminating the layers, all without curing the inner and outer surfaces of the liner.

The method of making a liner for a pneumatic tire which liner is composed of a plurality of layers, which method comprises curing or partially curing by irradiation at least only one face of a layer to which face is laminated a second layer, which irradiation rearranges the molecular structure of the layer, laminating the layers and making a band of the liner.

The method of making a liner for a pneumatic tire which tire is to be cured by a conventional method, the outer layer of which liner is adapted to contact the carcass of the tire and is curable by electron irradiation and the inner layer of which liner is adapted to face toward subsequent tire-inflating fluid and is composed of a butyl rubber, which method comprises curing or partially curing the inner portion of said outer layer by irradiation which rearranges the molecular structure thereof and laminating the layers, all without completely curing the outer surface of the liner, which is the surface which is adapted to contact the carcass.

The method of making a liner for a pneumatic tire, which liner is composed of a plurality of layers, which method comprises curing or partially curing at least a portion of the liner by irradiation which rearranges the molecular structure thereof and which portion is substantially coextensive with the liner, without curing the layer which is adapted to face toward subsequent tire-inflating fluid and without curing the surface of the liner which is adapted to contact the carcass of the tire, and laminating the layers.
