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.
Claims28
A method of making a golf ball comprising the steps of:
- forming a core;
- thermoforming a plurality of shells;
- positioning two of said plurality of shells to form a layer around the core;
- and
- forming a cover.
A golf ball comprising:
- a core;
- a plurality of thermoformed laminate layers;
- and
- a cover.
The golf ball of claim 27, wherein the first layer is proximal to the core and the at least one thermoplastic material comprises dynamically vulcanized thermoplastic elastomers, functionalized styrene-butadiene elastomers, thermoplastic rubbers, thermoplastic urethanes, metallocene polymers, ionomer resins, or blends thereof.
