Abstract

A golf ball is provided having a controlled weight distribution about a designated spin axis. The golf ball includes a core defining one or more high density regions interiorly disposed along a common plane and centered about the horizontal spin axis of the ball. As a result of the controlled weight distribution, the resulting ball significantly reduces hooks and slices. A method of manufacturing and/or utilizing the present golf ball is also provided.

Claims (12)

1. A golf ball comprising:

a core having one or more layers; and

one or more high-density regions interiorly disposed along a common plane in at least one of the core layers of the golf ball and centered about the horizontal spin axis of the ball, further comprising a cover disposed about said core, wherein the high-density regions are not visible to a golfer through the cover, the cover further comprising one or more markings, said markings providing a visible indicia of at least one of: (1) the gyroscopic center plane of the ball; and (2) a spin axis of the ball, the spin axis being perpendicular to the center plane and passing through a center of the ball.

2. The golf ball of claim 1 , wherein the one or more high-density regions comprise a continuous or discontinuous band of high-density material positioned along the gyroscopic center plane of the golf ball.

3. The golf ball of claim 2 , wherein the band is disposed in the outer layer of the core along a longitudinal axis which is perpendicular to the ball's spin axis.

4. The golf ball of claim 2 , wherein said band comprises two or more equally segmented parts radially disposed along a common plane.

5. The golf ball of claim 2 , wherein said band comprises three or more equally segmented parts radially disposed along a common plane.

6. The golf ball of claim 2 , wherein the band comprises from 2 to 12 equally spaced segments.

7. The golf ball of claim 6 , wherein the segments comprise high-density members which are radially equally spaced apart about a spin axis of the golf ball, and wherein each segment is located within the golf ball an equal distance from the spin axis.

8. The golf ball of claim 2 , wherein said band comprises five or more equally segmented parts radially disposed along a common plane and equal distance from the spin axis;

the cover comprises one or more cover layers; and

the one or more high-density regions comprise at least one continuous or discontinuous band of high-density material formed in at least one core layer.
