GOLF BALLS HAVING IMPROVED SHORT GAME PERFORMANCE
Golf balls having three-dimensional shaped fret areas and methods of making the same are disclosed. The three-dimensional shaped fret areas have at least three edges that meet at an apex point or an apex surface. The three-dimensional shaped fret areas may have a three-dimensional irregular pyramid shape or a three-dimensional truncated irregular pyramid shape. The three-dimensional shaped fret areas create golf balls having increased traction upon impact with the playing surface.
Golf ball having non-spherical dimples
A golf ball has a generally spherical surface and a plurality of dimples separated by a land area formed on the surface. The plurality of dimples includes a plurality of non-spherical dimples each having a non-axially symmetric plan shape, a varying edge angle, and a geometric centroid of the non-axially symmetric plan shape (GC). Each dimple cross-section of each non-spherical dimple consists of two arcs, each arc extending from a defined point of maximum dimple depth to a point at the land area of the golf ball. Each non-spherical dimple is oriented at an orientation angle, , relative to a reference line. The orientation angle is dependent on the position of the GC on the surface of the golf ball.
