Abstract: A method of removing parting line flash from a molded golf ball by use of low temperature cryogenic deflashing apparatus is disclosed. The cryogenic deflashing apparatus incorporates a rotating basket wherein the golf balls are placed and therein agitate them such that each ball will be evenly exposed to a recirculating blasting media. The low temperature environment causes the very thin gauge (0.003″) parting line flash to become embrittled relative to the ball and is deflashed by the blasting media, which comprises plastic pellitized shot.

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.

Abstract: An improved apparatus comprising a three plate mold for forming golf ball cores having dual parting lines. The mold comprises top, center and bottom plates, each having at least one mold insert with each insert having a cavity therein. The three cavities collectively form a spherical shape for molding a golf ball core. Upon the cores being formed, the center plate holding the cores, is lifted and rotated to a juxtaposed position against a stripping plate, whereby the cores are mechanically separated from both the mold and overflow flashing.

Abstract: The present invention relates to an improved apparatus for plasma treatment of golf ball surface. The improved apparatus comprises a cylindrical basket shaped rotating tumbler made from aluminum sheet metal that holds a plurality of golf balls within a sealed casing for surface preparation. A staggered hole pattern yields about 57% of open area in the tumbler surface to insure evacuation with minimum resistance. The holes are individually machined and have machined radiuses at each side of the sheet metal to allow for adequate coverage of a hard anodic coating which is necessary for protection of the sheet metal from the high intensity plasma. A two stage dry vacuum pumping system is used to reduce hydrocarbon impurities and improve print and paint adhesion.

Abstract: The present invention relates to method and apparatus for making golf ball cores. The method includes using an inspection system during preform formation to measure the perform. The measurements are used to determine the measured perform volume and compare it to a standard preform volume. The method also includes using mold with pairs of self-aligning half-molds. The apparatus for inspecting the preforms comprises a non-contact measuring device, such as a camera. The self-aligning half-molds each include an upper surface with an angularly offset portion. When the offset portions mate during mold closure, the half-molds move with respect to one another.

Abstract: An improvement in the manufacture of golf ball cores utilizing a three plate mold to form the cores therein providing the cores with dual parting lines.

Abstract: The present invention is directed to a method of forming a golf ball subassembly. After forming a partially-cured golf ball subassembly, the partially-cured subassembly is placed in a medium to continue curing until it is a substantially-cured subassembly. The medium in this embodiment is heated air and the subassemblies are moved through the heated air on a spiraled path. Subsequent to substantially curing the subassembly, it can be cooled in a cooling unit with a spiraled path. In one embodiment, the subassembly is a core, in another embodiment the subassembly is a core with a castable material thereabout.
