Claims
- 1. A golf ball comprising:
a center; and a wound layer surrounding the center to form a wound core, the wound layer being formed of at least one thread, and the wound layer including a plurality of radially extending sections, each section having a stress, and at least two radially extending sections have different stresses and the stress within each section being substantially constant. a cover comprised of an inner layer and an outer layer.
- 2. The golf ball of claim 1, wherein the thread further includes a cross-sectional area, and a first percentage variation in the stress within each section is less than a second percentage variation in the cross-sectional area of the thread within each section.
- 3. The golf ball of claim 1, wherein stresses are different by at least 10%.
- 4. The golf ball of claim 1, wherein in a radially outward direction the stress increases from one radially extending section to another radially extending section.
- 5. The golf ball of claim 1, wherein in a radially outward direction the stress decreases from one radially extending section to another radially extending section.
- 6. The golf ball of claim 1, further including at least two radially extending sections and each section has a thickness equal to at least 25% of a total wound layer thickness, wherein the stress of each radially extending section is different from the stress in the adjacent radially extending section.
- 7. The golf ball of claim 6, further including at least three different stresses.
- 8. The golf ball of claim 1, wherein the inner layer is comprised of a thermoset material selected from the group of thermoset vinyl resins, thermoset polyolefins, thermoset polyurethanes, thermoset polyureas, thermoset polyamides and thermoset acrylic resins.
- 9. The golf ball of claim 1, wherein the inner layer is a thermoplastic material with a flexural modulus of greater than 50,000 psi.
- 10. The golf ball of claim 1, wherein the inner layer is a thermoplastic non-ionomeric material selected from the group of vinyl resins, polyolefins, polyamides, acrylic resins, thermoplastic polyurethanes, olefinic thermoplastic rubbers, polyphenylene oxide resins, and thermoplastic polyesters.
- 11. The golf ball of claim 8, wherein the outer layer is a thermoplastic material having a flexural modulus of at least 50,000 psi.
- 12. The golf ball of claim 9, wherein the outer layer is comprised of a thermoset material selected from the group of polyurethanes and polyureas.
- 13. The golf ball of claim 1, wherein the thickness of each radially extending section is from about 0.007 inches to about 0.008 inches.
