20080315469 | METHOD OF PROVIDING A MOISTURE VAPOR BARRIER LAYER TO A CORE OF A GOLF BALL - A method of forming a water vapor barrier layer to a core of a golf ball is provided. The method includes placing the core of the golf ball into a vapor barrier composition, withdrawing the lifting device, and spinning and optionally oscillating the core within the composition for a time sufficient for the composition to form a layer on the core. The present invention also provides an apparatus that can be used to form a water vapor barrier layer on the core. | 12-25-2008 |
20080317892 | MOLD FOR A GOLF BALL - A golf ball mold having a non-planar parting surface that is formed a computerized modeling system such as CAD or CAE in combination with a CNC machine tool. The mold is comprised of hemispherical upper and lower mold halves being removably mated along the non-planar parting line that is distinct from the position corresponding to an equator line of the spherical cavity. Each mold half having an interior cavity detail for creating a pattern of dimples on the cover of the golf ball, wherein at least one dimple lies across an equator of the ball and the parting line passes around and between interdigitated dimples without intersecting them, therein creating a “seamless” golf ball. The non-planar surface of the upper mold half comprising at least three true sprues for venting of air and excess material; and at least three false sprues for the placement of tabs on the cover for use in aligning the golf ball as it is spun in a buffing machine. | 12-25-2008 |

20090286623 | THIN-LAYER-COVERED MULTILAYER GOLF BALL - A golf ball includes a core formed of an inner core and at least one outer core layer disposed about the inner core, one of which includes a surface amount of trans-polybutadiene and an interior amount of trans-polybutadiene at least 6 percent less than the surface amount. A cover containing an inner cover layer and an outer cover layer is formed over the core. The inner cover layer includes a block copolymer of styrene and butadiene, isoprene, or ethylene-butylene rubber and has a material hardness of about 60 to 70 Shore D. The outer cover layer is formed from a castable polyurethane or polyurea and having a material hardness of 55 Shore D or less. The inner core has an interior hardness and a surface hardness differing from the interior hardness by greater than 20 percent. | 11-19-2009 |
20100016099 | Method of Making a Golf Ball with a Multi-Layer Core - 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. | 01-21-2010 |
20100261553 | MULTILAYER GOLF BALL WITH A THIN THERMOSET OUTER LAYER - The present invention is directed towards a method of forming a multilayer golf ball which comprises a core, an inner cover layer and an outer cover layer. The steps include forming a golf ball core; molding an inner cover layer around said golf ball core with a material having a first shore D hardness; and casting an outer cover layer around said inner cover layer and golf ball core with a thermoset material having a second shore D hardness less than the first. The core is comprised of a center made from a first rubber based material and an outer layer formed from a second rubber based material. Preferably, the first rubber based material has about 15 to 25 parts of a crosslinking agent per hundred parts of rubber and the second rubber based material has about 20 to 40 parts of a crosslinking agent per hundred parts of rubber. | 10-14-2010 |
