Abstract
An improved apparatus and method for forming a golf ball is described. The method includes utilizing strands of a desired material. The method employs a top, center and bottom plate. The strands are placed over the concave cavities of a lower plate and over the hemispherical protrusions of a center plate. The three plates are then placed in a press, along with a top plate, thereby forming two sets of hemispherical shells. One set of shells remains in the cavities of the top plate, and one set remains in the cavities of the bottom plate. Centers are placed inside the hemispherical shells of the bottom plate. The two sets of shells are then brought together to form a complete core. A cover may be added to complete the formation of a golf ball.
