Abstract: A golf ball with multi-lobed dimples is provided. The dimple comprises a plurality of lobes positioned radially around the center of the dimple, wherein each lobe is defined by a circumferential segment. Each lobe comprises a first curved profile extending from the circumferential segment toward the center of the dimple and the first curved profile of each lobe abuts each other in an uninterrupted manner. The curvature of the circumferential segments can be defined by a ratio of an inside radius to an outside radius.

Abstract: A golf ball is provided that has improved aerodynamic efficiency, resulting in increased flight distance for golfers of all swing speeds, and more particularly for golfers possessing very high swing speeds, such as those who can launch the balls at an initial speed greater than 160 miles per hour and more particularly at initial ball speed of about 170 miles per hour or higher. The golf ball of the present invention combines lower dimple count with multiple dimple sizes to provide higher dimple coverage and improved aerodynamic characteristics.

Abstract: Provided herein is a golf ball that includes a generally spherical surface and an array of dimples formed on the surface. The undimpled portion of the spherical surface is the land area. At least one of the dimples includes a perimeter, a base, and a sidewall connecting the perimeter to the base. The sidewall forms an edge angle with the ball surface. The edge angle at a particular point on the perimeter is proportional to width of the land area adjacent to the point. Where the land area width is wide, the edge angle is high. Similarly, where the land area width is narrow, the edge angle is low. As the width of the land area in non-tessellated dimple patterns is determined by the position of the neighboring dimples, the edge angle varies cyclically around the perimeter, with the number of cycles corresponding to the number of neighboring dimples.

Abstract: 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.

Abstract: A golf ball product, or other non-streamlined body, having a dimple pattern in which at least some of the dimples overlap at least one adjacent dimple is disclosed. A new parameter called Overlap Saturation (OS) is disclosed. OS is the ratio of the number of overlap instances on a ball to the maximum possible number for an ideal hypothetical ball with the same number of dimples. Overlap instances are tallied by summing the number of overlapping neighbor dimples for every dimple. Golf ball products employing the disclosed dimple patterns have an increase in total yardage compared to an equivalent product without overlapping dimples.

Abstract: A golf ball is provided with a dimple pattern comprising two substantially identical elongated dimple pattern elements which fit together to form the complete dimple pattern. The dimple pattern can contain 344 dimples covering about 70.4% of the golf ball surface or 392 dimples covering about 73.3%, or other combinations of dimple count and coverage. The sizes of the dimples can be varied among either four distinct dimple sizes ranging from about 0.14 inches to about 0.17 inches or eight distinct dimple sizes ranging from about 0.11 inches to about 0.175 inches, or other dimple size combinations. The arrangement of dimples on the golf ball can be divided into a plurality of triangles having identical dimple arrangements with bilateral symmetry.

Abstract: A high performance golf ball having a reduced overall distance while maintaining the appearance of a high performance trajectory. The golf ball includes a combination of low CoR core and cover materials coupled with a less aerodynamic dimple pattern that achieves a reduction in carry and overall distance of 15 and 25 yards versus a conventional golf ball, while still providing the look, sound, feel and apparent flight of a conventional golf ball. A high performance golf ball having a reduced distance is also achieved by controlling dimensionless coefficients of lift/weight and drag/weight at certain Reynolds numbers and spin ratios for various CoR.

Abstract: An improved mold and method of making a golf ball product is disclosed. The mold parts are flared outward towards the parting line, which creates a golf ball product having a flared area around the equator. The flared area is provided to facilitate post-mold processing steps, particularly buffing. Dimples are formed on the outer surface of the golf ball product, including the flared area. The flared area is removed, resulting in a spherical outer surface having uniform dimples throughout, including the equatorial region. Thus, the flared area allows for more an improved post-buff golf ball product.

Abstract: A golf ball includes an outer spherical surface and a plurality of dimples formed thereon. In accordance to one aspect of the invention, the dimples have a polygonal perimeter and a concave depression. The concave depression satisfies only two of the following conditions: a substantially circular depression perimeter, a substantially spherical shape, and the depression contacting the perimeter of the dimple. In accordance to another aspect of the invention, one or more sides of the polygonal perimeter may be non-linear or curved. The dimples of the present invention may fill the ball's entire outer surface, or the dimples may occupy a predetermined pattern on the ball. The predetermined pattern may also include one or more channels or raised beads on the surface of the ball.

Abstract: An improved mold for making a golf ball comprises a pair of mold cups which are assembled together at an angular interlock. An upper mold cup has a projection rim that mates with a recess in the lower mold cup to provide for a substantially perfect registration, wherein the shift on the molded golf ball is minimized, and the parting line has a minimal amount of flashing that needs to be removed. The upper and lower mold cups have mating surfaces that can produce a corrugated parting line. Each mating surface comprising a plurality of peaks and valleys which are created by multiple radii, whereby when assembled the parting line follows the dimple outline pattern and allows the dimple outline pattern of one mold cup to interdigitate with the dimple outline pattern of the mating mold cup, to form a golf ball of substantially seamless appearance.
