Preparation of thread-wound golf balls |
摘要 |
Thread-wound golf balls are prepared by winding a rubber thread around a frozen core to form a core ball, immediately thereafter microwave heating the core ball to thaw the core, and forming a cover over the core ball. Microwave heating causes the frozen core to be briefly thawed without heating the thread rubber layer and without moisture condensation on the core ball surface, reducing the time taken for the core thawing step and eliminating the need for a drying step.
