Document Type and Number:
Japanese Patent JP2012040376
Kind Code:
A
Abstract:

To improve a conventional technology of a golf ball by additional golf ball options for affecting the flight, feeling and characteristic of the ball.

Golf balls may include a first pole, a second pole, and a seam located between the first and second poles. Dimples are formed on a surface of the ball in a pattern that includes a plurality of repeating sectors around each pole of the ball. The sectors on one ball half are rotationally offset across the seam line from the sectors on the other ball half. Additionally, each individual sector includes a line of symmetry over which the dimple pattern on one half of the sector is mirrored on the other half. A variety of different dimple types also may be arranged on a golf ball surface, e.g., within the sectors described above. Additional aspects of this invention relate to the features of various layers of a multi-piece golf ball and to methods of making golf balls having at least some of the above features.
