A method of making a golf ball core, including the steps of providing a plurality of centers; providing a top mold plate defining a first plurality of cavities, a bottom mold plate defining a second plurality of cavities corresponding to the first cavities, and a center mold plate disposed between the top and bottom mold plates and comprising a plurality of corresponding protrusions; forming a plurality of shells from a layer material by placing the layer material into the top and bottom mold plate cavities; and molding the layer material around the protrusions of the center plate by applying at least one of heat and pressure to the top and bottom mold plates such that the layer material has a different temperature than the mold plates; opening at least one mold plate from the center plate and placing the centers in the shells; and joining the top and bottom mold plates to join the shells around the centers.

Method for making multi-layered cores for golf balls

The present invention is directed to an automated molding machine and method for forming hemispherical components for a golf ball. The machine includes an L-shaped frame and three separate plates. The plates move between longitudinally spaced positions and vertically spaced positions. The machine also includes a rotating frame for inverting several of the plates during manufacture.
