The present invention is directed to improved cover compositions for golf ball construction and the resulting low modulus golf balls produced utilizing the improved cover compositions. The novel golf ball cover compositions of the invention comprise a blend of a relatively low amount of at least one hard ionomeric resins and a relatively large amount (i.e. from about 75 to about 85-90 percent) of at least one soft ionomer resin. When the cover compositions of the invention are utilized to manufacture golf balls, the golf balls produced thereby, exhibit properties of improved playability at low swing speeds without substantial sacrifices in durability and/or distance characteristics when compared to known hard-soft ionomer blends.

Low modulus covered golf balls

A new configuration for dimples on the surface of a golf ball is characterized by at least a portion of the bottom surface of the dimple having a raised contour which is still below the surface of the ball. The contoured portion may comprise many shapes including a crescent or a sinusoidal configuration. Moreover, the contoured portion may have different portions having different depths. The contours within at least some of the dimples on the surface of the ball alter the air flow across the golf ball surface to reduce drag and increase the distance the ball will travel.

Golf ball with contoured dimples

The present invention is directed to a golf ball comprising a solid core component that includes a relatively hard central portion and a relatively soft skin portion surrounding the central portion. Various preferred embodiment golf balls are disclosed utilizing this core configuration. A golf ball comprising the noted core component having a wound layer disposed about the core skin portion is described. Another preferred embodiment relates to the use of the noted core component having a multi-layer cover assembly surrounding the core. Various methods for producing such golf ball core components are disclosed.

The present invention is directed to improved molded golf ball core constructions and methods for improving the molded golf ball core construction. The molded 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.

Method of molding a golf ball

A solid golf ball comprising a solid core and a multi-layer cover assembly enclosing the core is disclosed. The core includes a center core component and one or more core layers enclosing the center core component. The multi-layer cover includes an inner cover layer generally disposed about the core and an outer cover layer enclosing the inner cover layer. In a preferred aspect, the present invention golf ball has a moment of inertia less than 0.43 oz. in and a coefficient of restitution of at least 0.760.

Multi-core, multi-cover golf ball

Disclosed herein is a golf ball comprising a spherical shell which includes at least an inner first layer, a second layer, and a third layer, the second layer being sandwiched between the first layer and the third layer, and a core which substantially fills the spherical shell, the core comprising at least one of a liquid, a gel and a melt. The sum of the thickness of the first layer, second layer and third layer is 0.10-0.30 inches. The core at least substantially fills the spherical shell without stressing the spherical shell. The spherical shell, as opposed to the core, is primarily responsible for the high initial velocity obtained when the golf ball is struck by a golf club so as to allow the golf ball to be driven long distances both in the air and on the ground when it lands. A method of making the golf ball also is disclosed. The golf ball is particularly well-suited for use by players seeking a long distance ball with a low spin rate.

The present invention is directed to improved molded golf ball core constructions and methods for improving the molded golf ball core construction. The molded 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.
