The present invention relates to dimples and dimple patterns for golf balls (), preferably dimple patterns composed of letters, symbols, logos and combinations thereof, inset into the cover of the golf ball (). The golf ball () has dimples () and logo depressions () in a cover of the golf ball (). The logo depressions () are preferably letters, symbols, logos and combinations thereof, inset into the cover of the golf ball ().

Dimples composed of letters or symbols inset into cover

A golf ball () having a low volume cover layer () is disclosed herein. The golf ball () has a cover layer () with a volume less than 0.1550 cubic inches. In a preferred embodiment, the cover layer () is composed of a reaction-injection molded polyurethane material. Preferably, the cover layer () has a plurality of deep depressions () with either a plurality of multi-faceted polygons () or dimples.

Low volume cover for a golf ball

A golf ball having traditional dimples and a tubular lattice structure is disclosed herein. The golf ball has dimples and a plurality of lattice members that form multi-faceted polygons. Each of the plurality of lattice members has an apex and the golf ball of the present invention conforms with the 1.68 inches requirement for USGA-approved golf balls. The interconnected lattice members form a plurality of polygons, preferably hexagons and pentagons. Each of the lattice members preferably has a continuous contour.

Aerodynamic pattern for a golf ball

An apparatus and method for demolding golf balls from a mold cavity are disclosed. More specifically, an apparatus and method for demolding a golf ball from a mold cavity subsequent to forming a cover layer without the use of ejector or knockout pins are disclosed. The molding apparatus utilizes an undercut configuration that, upon opening the molds after molding a golf ball, serves to impart a rotational force upon the ball and dislodge it from the molds.

Method and apparatus for demolding a golf ball

A golf ball comprising a core and a cover layer, wherein the cover layer provides one or more deep dimples having two or more different radii is disclosed. The deep dimples(s) extend(s) through the cover layer to and/or into a layer or component underneath. The cover may be a single layer or it may include multiple layers. The deep dual dimples may be spherical or non-spherical, and the portion of the dimple that extends to or into the next inner layer may be the same or different shape as the outer portion of the dimple.

Golf ball

A golf ball () having a plurality of primary dimples () with annular tubular portion () is disclosed herein. In a preferred embodiment, there are 332 primary dimples which cover a surface area ranging from 81% to 87% of the golf ball (). Also in a preferred embodiment, there are twenty different types of primary dimples (), which vary in diameter, chord depth and/or entry angle.

Dual dimple surface geometry for a golf ball

Aerodynamic surface geometry for a golf ball

Molding equipment and related techniques for forming a golf ball are disclosed. The golf ball comprises a core and a cover layer, wherein the cover layer provides one or more deep dimples that extend through the cover layer to and/or into a layer or component underneath are disclosed. The molding equipment provides one or more selectively positionable knock-out pins along the surface of the molding chamber. These pins are specially tailored such that subsequent to molding, the resulting voids are traditional or deep dimples. The molding equipment and related processes are particularly useful when forming the various layers by reaction injection molding.

Method and apparatus for forming a golf ball

A process for reaction injection molding a polyurethane material for a layer of a golf ball is disclosed herein. The layer is preferably a cover for the golf ball. The process discloses preferred pressure parameters and mass flow parameters for reaction injection molding the layer. Such preferred pressure parameters include the difference from mix-head open to the shot mid-point, &#x394;&#x394;Pom, and the pressure difference from mix-head open to close, or &#x394;&#x394;Poc. The mass flow parameters include the percentage change in mass flow ratio from mix-head open to shot mid-point, or % MFRom, and the change in mass flow ratio from mix-head open to shot mid-point, or &#x394;MFRom.

Method for manufacturing a golf product

A golf ball () having a non-planar parting line (), a first false non-planar parting line () and a second false non-planar parting line (). A first groupof parting dimples defines the non-planar parting line (). A second group () of parting dimples defines the first false non-planar parting line (). A third group () of parting dimples defines the second false non-planar parting line (). A plurality of hexispheres () are defined by the non-planar parting line () the first false non-planar parting line () and the second false non-planar parting line ().

Golf ball dimple pattern

A golf ball with a dimple pattern designed to maximize flight characteristics employs dimples which are created by joining two or more intersecting surfaces. The invention provides for single radius or dual radius dimples, preferably including smaller radius cylinders tangentially arranged along the side of the larger cylinders. The intersection of the cylinders forms tri-cylinders, tri-semicylinders, bi-cylinders, quad-semicylinders, penta-semicylinders, or more generally n-cylinders depending upon the number of intersecting cylinders. The golf ball includes a plurality of single or dual radius dimples created by intersecting n-cylinders to create maximum turbulence on the ball during flight.
