A new tire construction and method which makes the toe guard integral with the inner liner is provided. A tire is made using an inner liner that has a width substantially equal to the width of a prior art inner liner plus the width of prior art toe guards minus any overlap. The edges of the inner liner, which wrap around the bead, are reinforced so that the edges of the inner liner protect the bead area of the tire against damage caused by the rim or the mounting and dismounting procedure.

Tire construction combining the toeguard and inner liner

An open-torus radial ply pneumatic tire is configured for mounting on a specially designed rim. The special rim includes means for restraining the radially outward movement of the tire's rim securing regions, which are spaced apart regions of the rim in which the tire's radial carcass plies are anchored. In the rim securing regions, the carcass plies are turned axially outwardly and encased in a molded elastomeric material having a shape complementary with that of the restraining means of the special rim. The tire also includes a belt structure positioned radially outwardly of the carcass plies.

Tire and rim

The invention relates to a butt splicing technique for use in manufacturing reinforced elastomeric articles, in particular pneumatic tires. In the method, after a butt splice is made, a spun-bonded material is applied to the splice area as a splicing strip. The spun-bonded material has stress/strain/expansion characteristics that closely resemble such properties in an elastomeric component of the article which is spliced so that the splicing strip does not unduly distort the reinforcing structure of the component, while preventing opening of the splice during construction. Articles made using the method are also provided.

Pneumatic tire made by butt-splicing structural members and a method

A rubber tire having a vinylidene chloride copolymer/elastomer polymer blend inner liner is disclosed. This coating may be about 1 to 3 mils thick. The polymer blend has low air permeability, high elongation, low modulus and excellent flex resistance. The polymer blend may be prepared by combining an aqueous vinylidene chloride copolymer emulsion adjusted to pH of about 6.5 to about 8, with an elastomer latex, and applying the resulting mixed emulsion by conventional techniques to the inner surface of the carcas of inner liner of a green tire.

A metallic cable (10) suitable for reinforcing elastomeric articles comprises two or more substantially identical helical formed bare filaments (11,12,13) nested together and secured to one another by axially spaced apart applications of an adhesive substance.

Metallic cable

A method of making metallic cable (10) suitable for reinforcing elastomeric articles which comprises two or more substantially identical helical formed filaments (11, 12, 13) nested together and secured to one another by axially spaced apart applications of an adhesive substance.

Method of making a metallic cable

A metallic cable (10) suitable for reinforcing elastomeric articles comprises two or more substantially identical, helically disposed filaments (11, 12, 13) nested together and twisted together, such that the cable has a lay length (L) that is at least two times greater than the pitch length (P) of the filaments. The cable is manufactured by drawing metallic filaments from a bobbin means (31, 32, 33) and then guiding them through a means for deforming (34) that shapes the filaments into helixes. The filaments are positioned beside and against each other such that each filament is in contact with at least one other filament. After a sunken rotating pulley (37) guides the filaments through the hollow bearing (23) of a first flyer (21), first and second rotating flyers (21, 22) twist the helically disposed filaments together to form a cable.

Metallic cable and apparatus for manufacturing the same

A metallic cable comprises a strand of identical helical shaped filaments positioned beside and against each other such that each filament of the strand is in line contact with at least one other filament of the strand. The helixes of the filaments of the strand are sloped in a first direction. A single filament is twisted with the strand in a direction opposite to said first direction. An apparatus and a method for manufacturing the metallic cable are also disclosed.

Metallic cable and method and apparatus for making same

A metallic cable for reinforcing elastomeric articles comprises two strands of two filaments twisted together and having a cable lay length. The filaments of each strand are twisted together and the strands have strand lay lengths that are equal to one another but different from the cable lay length. The direction of twist of the strands may be either the same as, or opposite to the direction of twist of the cable.

Metallic cable for reinforcing elastomeric articles

A metallic cable comprises a strand comprising a plurality of parallel filaments twisted with another strand comprising at least one filament. The cable is manufactured using a two for one twist principle.

Manufacture of metallic cable

Brass coated steel tire cord is treated with vaporized benzotriazole and/or other treatment agents to promote corrosion resistance and cord to rubber adhesion retention.

Vapor treatment of metal tire cord

A tire having axially spaced rings of elastomeric material with different spring rates and tread configurations to provide variable operating characteristics at axially spaced positions across the tire. Each of the rings has an inner bead portion and an outer belt portion connected by a load-carrying and cushioning intermediate structure which may have radially extending strap members reinforced by a ply of reinforcing cords.

Multiple ring tire

A safety support mounted on a rim inside a tire chamber to resiliently support the tread portion of the tire in the deflated condition and maintain the bead portions of the tire in a separated condition. The support is in the form of a ring member of flexible resilient material with an inner portion at the inner periphery having a diameter not greater than the diameter of the rim and a width substantially the same distance between the bead portions when mounted on the rim. The ring member also has an outer portion at the outer periphery with an outer diameter less than the diameter of the tread portion of the tire in the inflated condition and greater than the diameter of the bead portions. The outer portion and inner portion of the ring member are connected by an intermediate portion which includes a plurality of radially extending webs spaced apart circumferentially of the ring member. The outer portion and inner portion are reinforced by annular plies which may be of bias fabric and helically wound cords.

Safety support assembly for pneumatic tires

A tire having an annular body of resilient elastomeric material with an outer member at the outer periphery which may carry a tread and an inner member at the inner periphery for mounting on a wheel rim. The inner member is supported and cushioned by a plurality of circumferentially spaced-apart wall members extending from the inner member to the outer member. The annular body may have one or more supporting rings and the wall members of adjacent rings as well as the wall members of the same ring may be offset circumferentially of the tire. The wall members provide a lateral spring rate and a variable radial spring rate across the tread of the tire. The wall members, tread, inner member and outer member may be reinforced by cords extending at bias angles or generally circumferentially of the tire. Sidewalls between the inner and outer members may also be provided for low pressure inflation and exclusion of foreign matter from the spaces between the wall members.

Tire with supporting and cushioning walls

A nonpneumatic tire with generally cylindrical inner and outer members connected by radial wall members mounted on a split rim with tire-retaining flanges and a generally cylindrical tire-supporting surface. The diameter of at least some portions of the rim tire-supporting surface is greater than the diameter of adjacent portions of the inner member of the tire for nonrotatable engagement of the tire by the rim in the mounted condition. The tire may include a layer of compressible material spaced radially inward from a reinforcing ply embedded in the inner member. The tire and rim may also have transversely extending, circumferentially spaced-apart ribs and grooves in meshing engagement to prevent rotation of the tire relative to the rim.
