Abstract
Official abstract text for this publication.
The present invention provides a golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least 20 percent of the dimples incorporate directional surface texturing therein. The directional surface texturing preferably comprises substantially parallel channels or protrusions formed within the dimples.
First claim
Opening claim text (preview).
What is claimed is: 1. A golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least 20 percent of the dimples incorporate directional surface texturing comprised of 2 or more substantially parallel linear channels having a U-shaped cross-section with a depth of less than 0.002 inch. 2. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises less than 400 dimples and at least 50 percent of the dimples incorporate directional surface texturing therein. 3. The golf ball of claim 1 , wherein a plurality of the dimples have linear channels that are disposed at an angle of between about 10 and 90 degrees with respect to linear channels of an adjacent dimple. 4. The golf ball of claim 1 , wherein a plurality of the dimples have linear channels that are arranged at an angle of about 90 degrees with respect to linear channels of an adjacent dimple. 5. The golf ball of claim 1 , wherein no dimple on the ball has an adjacent dimple with parallel linear channels. 6. The golf ball of claim 1 , wherein a plurality of dimples on the ball have an adjacent dimple with parallel linear channels. 7. The golf ball of claim 1 , wherein the linear channels within a dimple have different lengths. 8. The golf ball of claim 1 , wherein a plurality of the linear channels have a channel length that is at least 5 times a width of the channel. 9. A golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least 20 percent of the dimples incorporate directional surface texturing comprised of 2 or more substantially parallel linear protrusions having a V-shaped cross-section with a height of less than 0.002 inch. 10. The golf ball of claim 9 , wherein the outer surface of the golf ball comprises less than 400 dimples and at least 50 percent of the dimples incorporate directional surface texturing therein. 11. The golf ball of claim 9 , wherein a plurality of the dimples have linear protrusions that are disposed at an angle of between about 10 and 90 degrees with respect to linear protrusions of an adjacent dimple. 12. The golf ball of claim 9 , wherein a plurality of the dimples have linear protrusions that are arranged at an angle of about 90 degrees with respect to linear protrusions of an adjacent dimple. 13. The golf ball of claim 9 , wherein no dimple on the ball has an adjacent dimple with parallel linear protrusions. 14. The golf ball of claim 9 , wherein a plurality of dimples on the ball have an adjacent dimple with parallel linear protrusions. 15. The golf ball of claim 9 , wherein the linear protrusions within a dimple have different lengths. 16. The golf ball of claim 9 , wherein a plurality of the linear protrusions have a protrusion length that is at least 5 times a width of the protrusion.
