  • Patent number: 9492714
    Abstract: A method and system for making a golf ball core is disclosed. The method may generally include forming a golf ball core out of a raw core material. The golf ball core may be rapidly heated to begin curing (or vulcanizing) from the outermost surface toward the center of the golf ball core. Before curing the entire golf ball core, the golf ball core may be quenched to stop the curing process. As a result, the golf ball core may include an outer cured zone and an inner uncured zone. In this state, the golf ball core may be incorporated into a finished golf ball to be sold to consumers. Following a set of instructions provided with the golf ball, the consumer may heat the golf ball and a cure indicator to customize the properties of the golf ball core, and, thus, the characteristics of the golf ball.

  • Patent number: 9004798
    Abstract: A golf tee insertion depth measurement tool provides a gauge to facilitate marking the shaft of a golf tee to indicate a desired insertion depth that provides an optimum height for a golf ball placed on the tee, which ball is to be struck by a club face having a height H. The tool has a base portion and an elongate stem portion having a stem length. The base portion has a first surface and a second surface. The stem portion is connected to the base portion and extends outwardly away from the second surface of the base portion. The stem portion is first marked along its length at a location corresponding to the club face height H above the ground. The shaft of a tee is then marked at a location corresponding to the marked location on the stem portion to provide the correct insertion depth for the tee.

  • Patent number: 8529375
    Abstract: Generally disclosed is a golf ball having a core and a cover layer. The cover layer includes a coating material thereon that increases the golf ball's moment of inertia. The coating material is coated on the cover layer in a pattern corresponding to one of the dimple pattern and the pattern of land areas separating the dimples. The golf ball's moment of inertia is increased while utilizing only a small amount of the coating material as a result of the pattern of coating material, which locates the coating material at an outermost radial distance from the golf ball's center of rotation (i.e., the golf ball's center of gravity). The increased moment of inertia causes the golf ball to have a lower rate of spin when hit by a golf club, thereby displaying different play characteristics.

  • Patent number: 8362149
    Abstract: The invention provides a golf ball material composed of an ionomeric resin composition obtained by melt-blending under applied heat one or more compounds selected from among UV/EB-curable materials with, in the presence of a peroxide, a non-ionomeric thermoplastic resin and an ionomeric resin; or of an ionomeric resin composition obtained by using, instead of the ionomeric resin, an acid-containing polymer base of the ionomeric resin and subjecting the acid-containing polymer composition similarly prepared by melt-blending under applied heat to an acid-neutralizing reaction with a metal ionic species. Methods for preparing such a material, and golf balls which include as a component therein a molding made of the golf ball material are also provided. The golf ball material has a good thermal stability, flow and processability, and can thus be used to obtain high-performance golf balls endowed with an excellent abrasion resistance, scuff resistance, durability and flexibility without a loss of rebound.
