Patent number: 6797097Abstract: The invention provides a method for making a golf ball. Two cups are molded from an elastomer separately from an inner sphere. In one embodiment of the method, the cups are molded on both sides of a single mold part with hemispherical protrusions that form cavities in the cups. An inner sphere is placed within the cavities, and the cups are joined, by preferably crosslinking the cups together or applying adhesive there between. To retain the characterisitics of the cup material where the cups meet, an embodiment of the cups can be formed with nonplanar mating surfaces that mesh with each other. The nonplanar mating surfaces preferably have a pattern that is symmetrical about the inner sphere, such as concentric ridges, for example a tongue and a groove.Type: GrantFiled: January 3, 2003Date of Patent: September 28, 2004Assignee: Acushnet CompanyInventors: Herbert C.

Patent number: 6290610Abstract: The present invention is directed to an improved golf ball and a method of winding that includes measuring and controlling thread stress directly, rather than maintaining and controlling the level of tension on the threads. The golf ball includes a center, a wound layer that surrounds the center to form a wound core, and a cover that surrounds the wound core. The wound layer is formed of at least one thread, and the wound layer includes a plurality of radially extending sections, each section has a thread stress. The stress within each section is substantially constant, but at least two radially extending sections have different stresses. The method for winding thread onto a golf ball center to form a wound core comprises the steps of measuring a stress within a portion of the thread; winding the thread about the golf ball center while applying a force on the thread to form a plurality of portions with predetermined thicknesses and varying the stress between the portions.Type: GrantFiled: September 15, 2000Date of Patent: September 18, 2001Assignee: Acushnet CompanyInventors: Walter L.
