    Abstract: A pneumatic race tire has an elastomeric casing with a tread in the crown portion thereof, a pair of bead areas and a body ply carcass extending continuously between the bead areas and through the sidewalls and crown portion. A continuous thin annular band formed of a high strength, lightweight material such as metal, fiberglass, a composite material or the like is located radially inwardly of the tread and between the tread and body ply carcass to enhance tire performance by reducing the thickness of the tread area.

    Abstract: A run flat pneumatic tire has a thin annular band embedded in the crown portion of the tire. The band is formed of a multilayer composite formed of wound layers of a material such as fiberglass and/or graphite impregnated with a resin. The band has a radial cross-sectional thickness with a neutral axis extending through the center in an axial direction. The radial thickness of the band decreases from an axial midpoint toward outer ends of the band to provide greater thickness in the center of the band to reduce interlaminar shear fatigue.

    Abstract: A band element for mounting in the crown portion of a pneumatic tire to provide run flat ability to the tire in the event of loss of air pressure and to provide increased puncture resistance. The band is formed of flat strips of tape having fibers embedded in a resin matrix which are twisted and then pultrated to provide a rectangular cross sectional configuration. The twisted tape is wrapped about a mandrel and forms either the only layer, or the intermediate layer of a composite band in combination with inner and outer layers of flat tape or wound filament fibers, whereby the fibers in the tape extend across the central axis of the band to reduce interlaminar sheer. In another embodiment, a plurality of dimples or depressions are formed in the individual tape layers to extend a plurality of the fibers across the layer boundaries to reduce interlaminar sheer.

    Abstract: A run flat pneumatic tire is reinforced by a thin annular composite band imbedded in the crown portion of the tire in combination with a plurality of radial cords or plies in its sidewalls which have freedom in shear with respect to one another. The band is formed by a plurality of layers of material strips wherein each strip is wound in a helical pattern, with adjacent strips being wound at reverse angles to each other. Each layer is formed under sufficient pressure and at an elevated temperature whereby the band is prestressed in tension which decreases the maximum stress at the footprint area of the tire. The invention furthermore incorporates the method of imparting the prestress on the annular band during its manufacture.

    Abstract: A screen assembly for mounting on the outlet end of an extruder for removing foreign particles from an elastomeric material being discharged from the extruder. The assembly includes a screen support member having a plurality of spaced elongated ribs formed integrally with or removably mounted on a surrounding member. The spaced ribs form a plurality of elongated slots therebetween which provide flow paths for the elastomeric material, and preferably are concavely-shaped in the direction of travel of the extruded material. A mesh screen formed of a high tensile strength, work hardened stainless steel wire cloth is formed complementary to the concavity of the ribs and is mounted in juxtaposition to the ribs for removing the foreign particles as the elastomeric material passes through the screen. The concavity of the ribs and formation of the elongated material flow paths, reduce the amount of back pressure created in the elastomeric material and reduces the bending and shear forces created on the ribs and surrounding support member.

    Abstract: A runflat tire is provided that may be used in applications currently requiring a large aspect ratio tire. The runflat tire of the invention may be substituted in these applications while providing desirable ride characteristics. The runflat tire includes a sidewall with a radial portion and a cantilever portion. The cantilever portion may be fabricated by extending a sidewall insert in the axially inward direction or by extending the bead filler in the axially outward direction. In other embodiments, the cantilever sidewall portion is formed by a combination of the sidewall insert and the bead filler. The resulting runflat tire has desired durability in the uninflated operating condition while having desired ride characteristics in the inflated condition. The sidewall structure allows the tire to be used in applications presently requiring a tire with a high aspect ratio.
