Claim:
A method for forming a golf ball having a multilayer core, comprising: forming a first plurality of shells, wherein the steps for forming the first plurality of shells comprise: placing a first strand of layer material over a first mold plate, wherein the first mold plate defines a first plurality of cavities and wherein the first strand of layer material is placed over more than one of the first plurality of cavities; placing a center plate over said first mold plate, wherein said center plate defines a first plurality of protrusions on a first side of the center plate, and wherein said first plurality of protrusions are substantially aligned with said first plurality of cavities on said first mold plate; compressing the first strand of layer material between said first mold plate and said center plate so that it at least partially fills said first plurality of cavities to form said first plurality of shells; forming a second plurality of shells, wherein the steps for forming the second plurality of shells comprise: placing a second strand of layer material over more than one of a second plurality of protrusions on a second side of said center plate, wherein said second plurality of protrusions on the second side of the center plate are substantially aligned with said first plurality of protrusions; placing a second mold plate over said center plate, wherein said second mold plate defines a second plurality of cavities that are substantially aligned with said second plurality of protrusions on said center plate; compressing the second strand of layer material between said center plate and said second mold plate to form said second plurality of shells; wherein the steps of compressing said first and second strands of layer material are performed at substantially the same time.
