Abstract:
This invention is a golf ball (10) having dimples (12) which have a constant depth (dde). The bottom (12b) of each dimple is substantially the same size as the dimple opening defined by perimeter (12p). The golf ball (10) has a spherical outer surface (11) which is connected to the bottom (12b) of each dimple (12) through wall (12w), which is substantially perpendicular to the dimple bottom (12b), and the outer spherical surface (11) of the golf ball (10).
Abstract:
The present invention is directed towards a multilayer golf ball which comprises a core (2) with one or more layers; at least one cover layer (3); and one or more mantle layers (4) disposed between the core and cover layer, wherein the mantle layer comprises thermoplastic polyetherester, thermoplastic polyester, dynamically vulcanized thermoplastic elastomer, functionalized styrene-butadiene elastomer, thermoplastic polyurethane, metallocene polymer or blends thereof and thermoset materials.
Abstract:
A golf ball having a diameter of approximately 1.68 inches to 1.90 inches includes a fluid mass (18) at the center of the ball; a first, solid non-wound mantle layer (20) surrounding the fluid mass (18) comprised of a polymer material selected from the group of thermoset rubber material, thermoplastic elastomeric material and plastic, and having an inner diameter in the range of 30 % to 70 % of the ball diameter; a second, solid, non-wound mantle layer (22) surrounding and abutting the first mantle layer (18) and being a polymer material selected from the group of thermoset rubber material, and thermoplastic elastomeric material, and having an outer diameter in the range of 80 % to 98 % of the ball diameter, a hardness of approximately 30 Shore C to 95 Shore C, and a resiliency greater than 40 bashore; and a cover (11) surrounding the second mantle layer.
Abstract:
The present invention is directed to golf balls which have a lift to weight ratio greater than 1 to enhance the lofting time of the ball and thereby provide the golfer with a slow swing speed increased distance and improved trajectory. The golf ball has a core and a cover. The cover has dimples on its exterior surface. The golf ball weight ranges from about 1.35 ounces to about 1.62 ounces.
Abstract:
The present invention is directed towards a multilayer golf ball (1) which comprises a core (2), at least one cover layer (3), and one or more mantle layers (4) disposed between the core (2) and cover layer (3). The mantle layer (4) comprises thermoplastic co-polyether ester block copolymer, thermoplastic co-polyesther esther stock copolymer, dynamically vulcanized thermoplastic elastomer, functionally styrene butadiene elastomer, thermoplastic polyurethane, metallocene polymer or blends thereof, and thermoset materials and fillers, such as barium sulfate, zinc oxide, titanium dioxide or blends thereof. Further, the present invention is directed to a ball (1) having a core (2) having a compression less than 70, a mantle layer (4) having flexural modulus of less than 10,000 psi, a specific gravity of greater than about 1.2, and the cover (3) having a flexural modulus greater than 75,000 psi.

The present invention is directed towards a multi-layer golf ball (1) which comprises a core (2) with at least one cover layer (3); and one or more mantle layers (4) disposed between the core (2) and cover layer (3), wherein the mantle layer (4) comprises thermoplastic co-polyether ester block copolymer, thermoplastic co-polyester ester block copolymer, dynamically vulcanized thermoplastic elastomer, functionalized styrene-butadiene elastomer, thermoplastic polyurethane, metallocene polymer or blends thereof, and thermoset materials. Further, the present invention is directed to a ball (1) having a core (2) having a PGA compression less than 60, mantle layer (4) having a flexural modulus of less than 10,000 psi, and the cover (3) having a flexuralmodulus greater than 75,000 psi.
Abstract:
The invention includes a method of manufacturing a golf ball by placing a golf ball core (42) into a preform mold cavity, injection molding a cover around the core (42), placing the resultant preform (56) into dimpled compression mold cavities (76, 78) and compression molding the cover to define a golf ball. The invention also includes injection molding a golf ball preform (56) into an outer non-dimpled elongated spherical shape having an elongate axis, and compression molding a spherical golf ball from the preform (56) in substantially spherical dimpled compression mold cavities (76, 78).
