Abstract

A system and method for manufacturing a golf ball with one or more patterned film layers is disclosed. The system and method may involve creating a patterned film layer and applying the patterned film layer to the surface of a golf ball. The patterned film layer may include a layer of film having cutouts leaving the remaining portions of film in a pattern. The pattern may include a net pattern. The patterned film layer may include a material that is relatively harder or relatively softer than the surface of the golf ball. The method may include removing portions of film from a film material to create a patterned film material, cutting the patterned film material into sheets, molding two patterned film sheets into substantially hemispherical cups, and applying the two substantially hemispherical cups to a golf ball.

Claims

1. A method of manufacturing a golf ball with a patterned layer, comprising:

providing a golf ball, wherein the golf ball comprises a land area and a plurality of dimples;

forming a pattern on a film material by removing portions of film from the film material;

molding the film material with the pattern into substantially hemispherical cups of the film material with the pattern; and

then

applying the substantially hemispherical cups of the film material with the pattern to the land area of the golf ball to form the patterned layer, wherein the pattern on the film is aligned with the dimples of the golf ball.

2. The method according to claim 1, further comprising removing the portions of film with a die cutter.

3. The method according to claim 2, further comprising feeding the film material through a rotary die cutter.

4. The method according to claim 1, further comprising cutting sheets from the film material with the pattern.

5. The method according to claim 4, further comprising positioning the sheets of film material with the pattern between mold halves.

6. The method according to claim 5, further comprising positioning a bladder between the sheets of film material with the pattern while the sheets of film material with the pattern are positioned between the mold halves.

7. The method according to claim 6, further comprising molding the film material with the pattern into substantially hemispherical cups of the film material with the pattern by pressing the mold halves together and inflating the bladder between the sheets of film material with the pattern so that the bladder presses the sheets against mold portions of the mold halves.

8. The method according to claim 1, further comprising applying the substantially hemispherical cups of the film material with the pattern to the outer surface of a golf ball by positioning the substantially hemispherical cups of the film material with the pattern into mold halves and pressing a golf ball between the mold halves.

9. The method of claim 1, wherein the substantially hemispherical cups of the film material with the pattern form a patterned layer with a hardness different from the hardness of the outer surface of the golf ball.

10. A method of manufacturing a golf ball with a patterned layer, comprising:

providing a golf ball, wherein the golf ball comprises a land area and a plurality of dimples;

forming a pattern on a film material by removing portions of film from the film material in a pattern;

molding the film material with the pattern into substantially hemispherical cups of the film material with the pattern by placing film material with the pattern between a first set of mold halves; and

then

applying the substantially hemispherical cups of the film material with the pattern to the land area of the golf ball to form the patterned layer, wherein the pattern on the film is aligned with the dimples of the golf ball.

11. The method according to claim 10, further comprising heating the first set of mold halves.

12. The method according to claim 10, further comprising disposing adhesive between the substantially hemispherical cups of the film material with the pattern and the outer surface of the golf ball.

13. The method according to claim 10, further comprising applying the substantially hemispherical cups of the film material with the pattern to the outer surface of the golf ball by positioning the substantially hemispherical cups of the film material with the pattern into a second set of mold halves, positioning the golf ball between the substantially hemispherical cups of the film material with the pattern, and pressing the second set of mold halves together.

14. The method according to claim 13, further comprising heating the second set of mold halves.

15. The method according to claim 10, further comprising unrolling the film material from a roll of film material.

16. The method according to claim 15, further comprising cutting sheets of film material.

17. The method of claim 10, wherein the substantially hemispherical cups of the film material with the pattern form a patterned layer with a hardness different from the hardness of the outer surface of the golf ball.

18. A method of manufacturing a golf ball with a patterned layer, comprising:

providing a golf ball, wherein the golf ball comprises a land area and a plurality of dimples;

forming a pattern on a film material by removing portions of film from the film material in a pattern;

molding the film material with the pattern into substantially hemispherical cups of the film material with the pattern by placing film material with the pattern between a first set of mold halves, pressing the first set of mold halves together, and inflating a bladder between the first set of mold halves; and

then

applying the substantially hemispherical cups of the film material with the pattern to the land area of the golf ball, wherein the pattern on the film is aligned with the dimples of the golf ball.

19. The method according to claim 18, further comprising removing the portions of film with a die cutter.

20. The method according to claim 19, further comprising feeding the film material through a rotary die cutter.

21. The method according to claim 18, further comprising applying the substantially hemispherical cups of the film material with the pattern to the outer surface of the golf ball by positioning the substantially hemispherical cups of the film material with the pattern into a second set of mold halves, positioning the golf ball between the substantially hemispherical cups of the film material with the pattern, and pressing the second set of mold halves together.

22. The method according to claim 21, wherein the first set of mold halves and the second set of mold halves include substantially hemispherical shapes.

23. The method of claim 18, wherein the substantially hemispherical cups of the film material with the pattern form a patterned layer with a hardness different from the hardness of the outer surface of the golf ball.
