  • Patent number: 6298889
    Abstract: The invention is a process of manufacture, namely an automobile tire that is made of a colored composition that is of a single, inherent non-black color. The rubber composition of the tire is thus enhanced by the use of a coloring agent such as a pigment or dye that will yield a desired color upon completion of the tire manufacturing process. Such dye or pigment may be enhanced by the use of reflective, luminescent or photochromic agents that will enhance certain effects and appearances of the tire including: ease of visibility, other safety concerns including wear and puncture identification, and aesthetic appearance.

  • Patent number: 6221453
    Abstract: A fluorescent label can be used to identify the location of variations, e.g. radial variations, in a pneumatic tire so the tire can be precisely mixed and matched with other components such as tire rims which may have compensating variations. The fluorescent label desirably includes a release backing, a pressure sensitive adhesive to bind said label to a tire, a nontransparent face sheet that reflects a substantial portion of incident light back towards its source, transparent top layer which contains one or more fluorescent dye(s) disproportionately present in the surface portion of the layer and preferably in the layer nearest the adhesive side. The location of the largest portion of the fluorescent dye is important as commercial labels with the dye on the exterior surface suffer from fluorescent reading losses apparently due to migration of mobile molecules from other tires stored in contact with the label's exterior surface.

  • Patent number: 5124390
    Abstract: The invention relates to a whitened polymeric blend composition in which the whiteness is achieved by the substitution of from about 0 to about 20 parts per hundred rubber of calcium sulfate for from about 0 to about 20 parts per hundred rubber of titanium dioxide by volume. The invention allows for a reduction of up to 20 percent of the titanium dioxide, while maintaining a brightness of at least 85 as measured on the L scale of the Minolta Chroma Meter test.

  • Patent number: 5058647
    Abstract: Tires having white sidewalls are very popular in the United States and Canada. Tires having white lettering thereon are also very popular. This invention discloses a process for preparing such tires having decorative appliques thereon. By practicing the process of this invention, tires having better uniformity can be built at lower costs than when standard tire building techniques are utilized. This invention specifically relates to a method of preparing a pneumatic rubber tire having a decorative design on the sidewall thereof which comprises (a) applying the decorative applique to the sidewall of an uncured tire and (b) curing the tire; wherein the decorative applique is comprised of from about 25 weight percent to about 75 weight percent syndiotactic 1,2-polybutadiene having a melting point which is within the range of about 70.degree. C. to about 160.degree. C.

  • Patent number: 5047110
    Abstract: An apparatus and technique for applying markings or decorations to the sidewall of a cured tire. A thin polyester carrier sheet has a thermoplastic transfer stock thereon. A heated die is provided having thereon the geometric configuration of the desired marking or decoration. The heated die is urged against the transfer laminate to impinge the transfer stock against the sidewall of the cured tire. The heat of the die effects a release of the transfer stock from the carrier sheet in areas congruent with the indicia carrier by the die. The affinity of the transfer stock for the tire is greater than its affinity for the carrier sheet and the transfer is thus made.

  • Patent number: 4967820
    Abstract: A white sidewall band for radial ply tires consisting of upstanding wall areas extending axially outward from surrounding sidewall areas and having white rubber disposed radially across the width of the band and recessed axially inward from one wall area to the other. Sidewalls of this type can be made using buffing stones having buffing surfaces of convex cross-section, and result in white sidewalls protected from dirtying during transportation, storage, and the like without introducing structural weakness in the sidewall area.

  • Patent number: H1871
    Abstract: A curable rubber compound having enhanced tack and rubber articles and components, such as tires and treads, made therefrom. Compounds of the invention do not contain wax in an amount that is in excess of the wax's solubility in the rubber. Treads made from compounds of the invention generally do not require cement to secure their splices. Compounds of the invention typically include a formulated fatty acid or alkylated aromatic or phenolic resin, carbon black, natural and/or synthetic rubber, paraffinic or naphthenic oils, and a curing agent. Compounds of the invention have a tack of at least about 3 Newtons. Rubber compounds of the invention, and rubber components made therefrom, can be protected from ozone attack and oxidation by coating an outer surface of the compound and/or component with wax. Treads protected using these methods should have the wax applied to their outer surface subsequent to securing any tread splice.
