  • Patent number: 10293213
    Abstract: The present invention is directed to a golf ball having a non-planar parting line about non-circular dimples on its spherical surface. The parting line comprises non-concentric arcs having straight connecting line segments between the arcs. Each arc maintains a tangency with its connecting lines and a relief distance greater than or equal to 0.003 inches when measured from an average non-circular dimple diameter to one of the non-concentric arcs and an absolute relief distance of at least 0.001 inches when measured from all points on the non-circular dimple perimeter to one of the non-concentric arcs. The sum of the lengths of the non-concentric arcs relates to the sum of the straight connecting line segments according to the equation: (0.15)?LARCS??LLINES?(0.50)?LARCS.

  • Patent number: 9649536
    Abstract: The present invention is directed to a golf ball comprising of non-concentric arcs defining a non-planar parting line on its spherical surface resulting in having a large size disparity between non-circular dimples in one hemisphere and adjacent non-circular dimples from the opposing hemisphere. The parting line is produced by a pair of adjacent non-circular dimples, wherein ?d indicates the average non-circular dimple diameter and N indicates dimples from the Northern hemisphere and those from the Southern hemisphere are indicated by S. A large disparity may be created, if the following condition is satisfied: ? d ? ( N ) ? d ? ( S ) > 1.25 ? ? or ? ? ? d ? ( N ) ? d ? ( S ) < 0.80 .

  • Patent number: 8414428
    Abstract: A golf ball mold having a non-planar parting surface formed by superimposing a base waveform with a least one shorter secondary waveform. The base waveform is defined by a series of concentric arcs wherein adjacent arcs are connected with a straight line segment that is tangent to the arcs and creates an acute angle. The length of the straight line segment being critical to the accuracy and predictability of the parting line.
