Abstract: A golf ball comprising a core and a cover layer, wherein the cover layer provides one or more deep dimples that extend through the cover layer to and/or into a layer or component underneath is disclosed. The cover may be a single layer or it may include multiple layers. If the cover is a multi-layer cover, the dimples extend to or into at least the first inner cover layer, and may extend to and/or into two or more inner cover layers. If the cover is a single layer, the dimples extend to and/or into the core. The cover layer(s) may be formed from any material suitable for use as a cover, including, but not limited to, ionomers, non-ionomers and blends of ionomers and non-ionomers. The dimples may be spherical or non-spherical, and the portion of the dimple that extends to or into the next inner layer may be the same or different shape as the outer portion of the dimple. Optionally, a moisture barrier layer may be present between the core and/or the cover layer(s).

Abstract: Molding equipment and related techniques for forming a golf ball with one or more deep dimples are disclosed. The golf ball comprises a core and a cover layer, wherein the cover layer provides one or more deep dimples that extend through the cover layer to and/or into a layer or component underneath are disclosed. Preferably, the deep dimples are at least twice the depth of conventional dimples, more preferably, three or four times the depth of the conventional dimples. The deep dimples may be spherical or non-spherical, and the portion of the dimple that extends to or into the next inner layer may be the same or different shape as the outer portion of the dimple.

Abstract: 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 one or more polyurethane materials. 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.

Abstract: An apparatus and related techniques for making a golf ball having one or more deep dimples are 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 the material flow inlet and the molding cavity. The molding cavity includes at least one outwardly extending protrusion that forms a deep dimple that extends through the cover of the golf ball to and/or into the underlying component of the golf ball upon molding. The outwardly extending protrusion has a height greater than or equal to the thickness of the cover.
