    摘要: A unique set of preferred embodiment golf balls is disclosed as follows. In one aspect, a multi-layer golf ball utilizes a particular blend of ionomers in either or both of the cover layers. Preferably, the blend includes a minor percentage of high acid ionomers with a major percentage of low acid ionomers. In another embodiment, golf balls having relatively thin multi-layer cover assemblies are provided. The thicknesses of these cover layer assemblies range from about 0.015 inches to about 0.045 inches. Also, cover assemblies utilizing one or more thermoplastic polyurethanes are disclosed. The multi-layer core assembly used in the golf balls preferably exhibits a PGA compression of less than 85.

    摘要: An apparatus for making a golf ball is disclosed. The apparatus is a molding assembly for making a golf ball which includes a mold body that defines a molding cavity. The molding cavity is adapted to accommodate and preferably retain a golf ball core during a molding operation of one or more layers about the core. The molding assembly includes at least one material flow inlet, at least one material flow channel extending between and providing fluid communication with a material flow inlet and the molding cavity. At least one portion of the material flow channel has a plurality of bends and at least one branching intersection adapted to promote turbulence in a liquid flowing therethrough. A method of making a golf ball is also disclosed. A golf ball made from the disclosed molding apparatus and/or process is also disclosed.

    摘要: The present invention is directed to a golf ball comprising a dual core assembly and a cover layer. The dual core comprises an interior spherical center component formed from a thermoset polymeric material, a thermoplastic polymeric material, or combinations thereof. The center component comprises one or more density adjusting filler materials dispersed throughout the polymeric material. The dual core also comprises a core layer disposed about the center component, formed from a thermoset material, a thermoplastic material, or combinations thereof. The present invention golf ball may further comprise an outer core layer that surrounds the dual core. The cover layer is either a single cover layer or a multi-layer cover assembly and preferably includes a polyurethane material. It is preferred that the inner and outer cover layers differ in hardness by at least 5 on the Shore D scale. The resulting multi-layered golf ball of the present invention provides for enhanced distance without sacrificing playability or durability when compared to known multi-layer golf balls.
