Abstract
A method of making molds for the production of golf balls is disclosed. A hob is made having an imperfectly spherical arcuate surface that is composed of at least two different arcs in continuous arrangement to each other. A mold half is formed using the hob so that the imperfectly spherical hob creates an imperfectly spherical golf ball cavity within the mold half. When used to make golf balls, the imperfectly spherical cavity results in golf balls having a higher degree of sphericity than golf balls made by spherical hobs and mold half cavities.
Claims23
The method of making a golf ball mold half which comprises:
- a. forming a golf ball hob having an arcuate surface defined by at least two arcs having different center points;
- b. contacting the arcuate surface of the golf ball hob with a golf ball mold blank;
- and
- c. applying pressure to cause a negative of at least the arcuate surface of the golf ball hob shape to be imparted to the golf ball mold blank to form the golf ball mold half.
The method of making a golf ball mold half which comprises:
- a. forming a golf ball hob having an imperfectly spherical three-dimensional contour;
- b. contacting the contour of the golf ball hob with a golf ball mold blank;
- and
- c. applying pressure to cause at least a negative of the contour of the golf ball hob shape to be imparted to the golf ball mold blank to form the golf ball mold half.
A method of making a golf ball comprising:
- a. providing first and second golf ball mold halves, each mold half having a cavity with an arcuate surface defined by at least two arcs having different center points;
- b. placing a golf ball subassembly into a golf ball mold cavity defined by the cavity of the first golf ball mold half and the cavity of second golf ball mold half;
- and
- c. disposing a cover material within the golf ball mold cavity around the subassembly.
