  • Patent number: 6812317
    Abstract: A golf ball and a method of making a golf ball that includes a center formed from a material including polybutadiene and having a high resilience, at least one cover layer formed of a material including polyurethane, and at least one wound layer of a tensioned material windings between the center and the cover. The polyurethane composition is formed from the reaction product of at least a prepolymer of a polyisocyanate and a polyol, and a diamine curing agent. The polybutadiene composition includes a butadiene polymer with a resilience index greater than about 40 and a weight average molecular weight greater than about 200,000. Such golf balls can have a coefficient of restitution that is optimized for low swing speed players. The wound layer of the present invention may be applied to golf balls having liquid or solid centers to achieve desired golf ball characteristics.

  • Patent number: 6797097
    Abstract: The invention provides a method for making a golf ball. Two cups are molded from an elastomer separately from an inner sphere. In one embodiment of the method, the cups are molded on both sides of a single mold part with hemispherical protrusions that form cavities in the cups. An inner sphere is placed within the cavities, and the cups are joined, by preferably crosslinking the cups together or applying adhesive there between. To retain the characterisitics of the cup material where the cups meet, an embodiment of the cups can be formed with nonplanar mating surfaces that mesh with each other. The nonplanar mating surfaces preferably have a pattern that is symmetrical about the inner sphere, such as concentric ridges, for example a tongue and a groove.

  • Patent number: 6787091
    Abstract: A method of molding a layer of a thermoset or thermoplastic material around a golf ball component within a mold, in which the component is positioned within a mold cavity defined by opposing mold portions of the mold, to leave a cavity space between the component and the mold portions. A reaction mixture comprising at least two reactants is injected under a hydraulic pressure into the cavity space. The pressurized reaction mixture pushes the mold portions apart from each other to a partially open position with an opening therebetween. The reaction mixture is allowed to react partially within the cavity space, and then the mold portions are compressed toward each other to the closed position. The reaction mixture further reacts to form the layer of the thermoset or thermoplastic material immediately about the component.
