摘要： A game ball having a cover formed from a crosslinkable thermoplastic polyurethane is disclosed. Various types of game balls are described, including golf balls and softballs. By selective exposure to radiation, the thermoplastic polyurethane cover is crosslinked and its hardness is increased. Typically, increases in hardness values of at least 2 units on the Shore D scale are realized upon exposure to 3.5 Mrads of gamma radiation.

摘要： A golf ball is provided having a controlled variable moment of inertia. The golf ball includes a core defining at least one hollow channel. At least one movable weight is located within each hollow channel. The end of the hollow channel at the outer edge of the core is enclosed with a plug. The movable weight and plug may each further include a magnet or the hollow channel may include a placement member such as a spring to control the movement of the weight. When the present golf ball is struck, the spin rate forces the weights to move from the interior of the core outwardly towards the outer edge of the core, thereby varying the moment of inertia of the golf ball. A method of manufacturing the present golf ball is also provided. The golf ball also significantly reduces hooks and slices due to the gyroscopic effect of the moving weight(s) to the outer edge of the core.

摘要： The present invention is directed to a solid, non-wound, golf ball comprising two or more core components, and a cover component. The core components comprise i) an inner, high density, spherical center component comprising a blend of powdered metal and a first matrix material selected from the group consisting of thermoset material, a thermoplastic material, or combinations thereof; and, ii) an outer core layer disposed about the spherical center component, formed from a second matrix material selected from the group consisting of a thermoset material, a thermoplastic material, or combinations thereof. The golf ball may further comprise a second or additional outer core layer(s) that surround the first outer core layer. Preferably, the inner, high density, center component is produced without the use of a crosslinking agent or coagent, which is the reaction product of an unsaturated carboxylic acid or acids and an oxide or carbonate of a metal such as zinc. The cover may be single or multi-layered. For a multi-layered cover, the inner cover layer is comprised of a low or high acid ionomer or ionomer blend and the cuter cover layer is comprised of a soft, very low modulus ionomer or ionomer blend, or a non-ionomeric thermoplastic elastomer such as polyurethane, polyester or polyetheramide. The resulting golf ball of the present invention provides for enhanced playability characteristics (i.e., spin and feel) without sacrificing distance or durability properties.

In one preferred embodiment, the present invention golf ball includes a dual core having a center component of a thermoset material and a core layer of a thermoplastic material and a cover layer disposed about the core. The cover layer includes an inner cover layer with a Shore D hardness of 65 or greater and an outer cover layer having a Shore D hardness of 65 or less. In another preferred embodiment, the golf ball includes the previously noted dual core and a cover layer that includes an inner cover layer having a Shore D hardness of 65 or less and an outer cover layer of 65 or greater. In yet another preferred embodiment, the golf ball, as noted, includes the previously described dual core and a cover layer that includes a single outer cover layer having a Shore D hardness of from about 40 to 80. The center component of the preferred dual core has an outer diameter of from about 0.500 inches to about 1.250 inches. And, the preferred dual core has an outer diameter of from about 1.250 to about 1.600 inches.

摘要： The present invention is directed to golf ball core constructions and methods for forming the golf ball core construction. The golf ball comprises a molded spherical core having a soft skin integral therewith, and a cover molded over the core. The soft skin is formed by controlling exothermic molding temperatures. A slug is placed in a mold cavity which is then closed. A steam set point is set, and steam is applied for a 25-30 minute period such that a maximum mold temperature exceeds the steam set point. In the alternative, the core surface may be softened by first immersing a slug in water prior to subjecting the slug to conventional molding conditions.
