Abstract: The present invention is directed to multi-layer golf balls having a center, a cover layer, and at least one intermediate layer between the core and the cover layer. The center, the at least one intermediate layer and the cover are constructed to have different initial velocities and COR such that the gradients of initial velocities and COR progress from a slower center to a faster cover.

Abstract: A golf ball that is formed by a mold developed from a computerized modeling system such as CAD or CAE in combination with a CNC machine tool which superimposes a short waveform, or multiple waveforms, onto a longer base waveform to create a non-planar parting line that is functionally dependent on the underlying dimple geometry. The non-planar parting line is comprised of a plurality of peaks and valleys that are offset from the dimple perimeters, as not to bisect any dimple edge. Also, dimples on one side of the parting line interdigitate with dimples on the other side to form a more uniform distribution of dimples over the entire golf ball surface. Still further, the non-planar parting line has a amplitude which is less than 0.02 inch from an axis substantially coincident with the equator of the ball and the length of the parting line is less than 110 percent of the length of a curve defined by the circumference of the equator.

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: A golf ball comprising an outer surface including a plurality of dimples that form indicia. The plurality of dimples take the form of text letters, characters or other symbols and are relatively similar in size to a plurality of conventional shaped dimples or larger. The plurality of dimples occupy a substantial portion of the ball's surface in a repeating, distributed pattern.

Abstract: A multi-lobed golf ball dimple 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 and may be further defined by spoke-like ridges. 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 multi-lobed dimple may include uniform and non-uniform dimples. The curvature of the circumferential segments can be defined by a ratio of an inside radius to an outside radius. Each dimple also includes a slightly convex floor that is continuous and smooth. The curvature may match that of the outer surface of the golf ball. Further, a sloped wall interrupted by spoke-like ridges may connect the convex floor with the outer surface of the golf ball.

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 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 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: A golf ball with aerodynamic coefficient magnitude and aerodynamic force angle, resulting in improved flight performance, such as increased carry and flight consistency regardless of ball orientation.

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: 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.
