Abstract: The present invention is a golf ball which comprises spherical-cosine dimples on the surface thereof. The spherical-cosine dimples have a cross-sectional shape defined by the superposition of a spherical function and a cosine function. Each of the spherical-cosine dimples preferably has a dimple diameter of 0.180 inches or greater.

Abstract: The present invention provides a method for arranging dimples on a golf ball surface in which the dimples are arranged in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron. The method includes choosing control points of a polyhedron, generating an irregular domain based on those control points, packing the irregular domain with dimples, and tessellating the irregular domain to cover the surface of the golf ball. The control points include the center of a polyhedral face, a vertex of the polyhedron, a midpoint or other point on an edge of the polyhedron and others. The method ensures that the symmetry of the underlying polyhedron is preserved while minimizing or eliminating great circles due to parting lines.

Abstract: The present invention provides a golf ball having an aerodynamic subsurface for packing dimples. More particularly, the invention relates to a golf ball having an exterior surface and at least a first subsurface containing at least two dimples located solely on the subsurface and lying below the exterior surface of the golf ball. A transition zone between the exterior surface and the subsurface is disclosed having an angle of transition and a top radius and a bottom radius. According to the present invention, the exterior surface and at least the first subsurface have at least a first and second surface textures that are different.

Abstract: Golf balls comprising a core having at least one layer and a cover having at least one layer are provided. At least one of the layers is made from a thermoplastic composition preferably comprising a borophene material. Mixtures of borophene material and polybutadiene rubbers or ethylene acid copolymers can be prepared. The borophene-containing compositions can be used to make a core layer having good strength and impact durability and it also should help provide the ball with high resiliency.

Abstract: Golf balls and golf ball components made using three-dimensional (3D) additive manufacturing systems are provided. The golf ball includes at least one three-dimensional piece. Preferably, a continuous liquid interface printing method is used to make the three-dimensional structure. Ultraviolet (UV)-light polymerizable materials are used in the method. The method may be used to make single-piece or multi-piece balls. For example, the ball may include an inner core produced by the liquid interface printing method. An outer core layer may be disposed about the inner core, and a cover comprising inner and outer cover layers may encapsulate the core assembly to form the finished golf ball. The outer core and cover layers may be made using conventional molding technologies or the methods of this invention.

Abstract: The present invention is directed to a golf ball having a non-planar parting line on its spherical surface. The plurality of dimples located adjacent to the parting line consists of a first portion of dimples, each dimple of the first portion having a wave relief distance of from 0.001 inches and 0.005 inches, and a second portion of dimples, each dimple of the second portion having a wave relief distance of greater than 0.008 inches, where wave relief distance is measured as the shortest distance from the average dimple diameter of the dimple to the parting line.

Abstract: The present invention concerns a golf ball having dimples with a cross-sectional profile comprising a conical top portion and a non-conical bottom portion. More particularly, the profiles of the present invention are defined by three independent parameters: dimple diameter (DD), edge angle (ΦEDGE), and saucer ratio (Sr). These parameters fully define the dimple shape and allow for greater flexibility in constructing a dimple profile versus conventional spherical dimples. Further, conical dimples provide a unique dimple cross-section which is visually distinct.
