摘要： The present invention is directed to a golf ball comprising a soft core and a hard cover to produce a golf ball having a reduced spin rate. The present invention is also directed to an improved golf ball comprising at least one interior layer and/or a core comprising a silicone material. It is preferred to also utilize a multi-layer cover in conjunction with the silicone materials. The golf ball of the present invention may also utilize an enlarged diameter which serves to further reduce spin rate. The resulting golf ball exhibits properties of reduced spin without sacrificing durability, playability and resilience.

摘要： The present invention is directed to improved multi-layer golf ball compositions and the resulting regulation balls produced using these compositions. In this regard, a lighter core is produced and metal particles, or other heavy weight filler materials, are included in the cover compositions. This results in a molded golf ball exhibiting enhanced interior perimeter weighting. Preferably, the particles are included in an inner cover layer (or mantle) of a solid, three-piece multi-layered golf ball. The weight of the core is reduced in order to produce an overall golf ball which meets, or is less than, the 1.62 ounce maximum weight limitation specified by the United States Golf Association. It has been found that the combination of the present invention produces a golf ball with an increased moment of inertia and/or a greater radius of gyration and thus generates lower spin. This results in a golf ball exhibiting enhanced distance without substantially effecting the feel and durability characteristics of the ball.

摘要： Disclosed herein is a multi-layer golf ball having a soft outer cover. The golf ball has an inner cover layer with a Shore D hardness of 60 or more, and an outer cover with a Shore D hardness of 55 or less, and more preferably 50 or less. In a particularly preferred form of the invention, the outer cover comprises at least 75% of a soft copolymer formed from a polyolefin, an unsaturated carboxylic acid, and a monomer of the acrylate ester class. The golf ball of the invention has exceptionally soft feel and high spin rates on short shots of 80 yards or less and, particularly, 40 yards or less, while maintaining good distance and average spin on full shots.

摘要： The present invention is directed to an improved multi-layer golf ball comprising a core, an inner cover layer and an outer cover layer. The inner cover layer is comprised of a relatively hard cover material. The outer 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 polyesteramide. The outer cover layer exhibits a Shore D hardness of less than 50D. The golf ball may further comprise an optional mantle layer, which may include one or more filler materials. Filler material may be incorporated in one or more of the core, inner cover layer, or outer cover layer. The resulting multi-layered golf ball of the present invention exhibits reduced slippage between the ball and club face, and therefore, relatively high spin rates.

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) a small, inner, high density, spherical center component comprising a blend of powdered metal and a first matrix material comprising polybutadiene and polyisoprene; 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.

摘要： A method for forming non-circular dimples in a spherical surface is characterized by the use of a pantograph to repeatedly translate a master dimple configuration into the spherical surface. A drill bit is drilled into a portion of the spherical surface to a first depth. The drill bit is displaced relative to the surface by the pantograph along a given path without altering the axial orientation of the bit in order to form a non-circular dimple in the surface. The bit is removed from the surface and the process is repeated across other portions of the surface to form identical dimples therein.

摘要： A golf ball utilizing a high density core component, which is preferably part of a multicomponent core assembly is disclosed. The high density core component is preferably in the form of a metal sphere. The golf balls exhibit a unique combination of a relatively high coefficient of restitution, a controlled moment of inertia, and a relatively high spin rate during short distance shots. It is preferred that the high density core component be utilized in conjunction with a multi-layer cover assembly.

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.
