Abstract
A method for making a multilayer golf ball including a solid center having a center hardness, a plurality of laminates cut into a plurality of shapes formed around the center to create an inner ball, and a cover formed around the inner ball, wherein the plurality of layers can include at least a first layer having a hardness greater than the center hardness and a second layer having a hardness greater than the first layer hardness, and optionally a third layer disposed between the first and the second layers having a hardness greater than the first layer hardness.
Claims21
A method of making a golf ball comprising the steps of:
- forming a core;
- thermoforming a plurality of shells, wherein the plurality of shells are formed from a roll stock comprising a plurality of lamination layers, and wherein at least one lamination layer is formed from a thermoset polybutadiene material;
- positioning two of said plurality of shells to form a layer around the core;
- and
- forming a cover.
A method of making a golf ball comprising the steps of:
- forming a core;
