A manufacturing assembly and a method for locating a face insert in a golf club head during manufacture are disclosed herein. In particular, the manufacturing assembly comprises a face locating fixture sized to receive a golf club face insert and a pick fixture configured to removably attach to the face insert. The manufacturing assembly may further comprise a holding fixture sized to receive a golf club head and hold it in place while the face insert is aligned with the head during assembly.

A screw comprising a drive part, a threaded part, and a retaining ring is disclosed herein. Each of the drive part and the threaded part comprises a plurality of interface surfaces that transmit torque from the drive part to the threaded part and prevent the parts from disengaging from one another during use. Each plurality of interface surfaces forms one or more geometric shapes that create additional friction between the drive and threaded parts, and may further include mating pins and holes to prevent the parts from detaching from one another. The retaining ring, which removably connects the screw to a wrench during assembly of the screw with a receptacle, is disposed within a cavity formed when the drive part is assembled with the threaded part.

A heating apparatus () and method for heating golf clubs () during assembly is disclosed herein. The heating apparatus () preferably includes a frame (), a club retention mechanism (), a rotating mechanism () and a heating mechanism (). The heating apparatus () is used to cure an adhesive to bond a shaft () to a golf club head ().

Heating device for the manufacture of golf clubs

A process and apparatus for installation of a handgrip on a golf club shaft is disclosed herein. The handgrip is installed on the golf club shaft wrapped in a double-sided water activated tape. The method and apparatus utilizes a minimal amount of water to provide an initial grip strength greater than 18 foot-pounds. The apparatus has a shaft retention device, a grip attachment device and a misting device.

A gasket assembly for interposition between a mating, mutually-opposed pair of curved surfaces. The gasket includes a flexible metal retainer, and at least one seal element which is supported on the retainer along at least a portion of the inner or outer perimeter thereof. In a stressed state, such as under compression between two curved interface surfaces, the retainer is made to conform to curvatures of the surfaces. However, upon being removed from compression, the retainer substantially recovers to its normal state.

Resilient elastomer and metal retainer gasket for sealing between curved surfaces

A gasket assembly for interposition between a mating, mutually-opposed pair of curved surfaces. The gasket includes a resilient retainer formed of a metal material and having an inner perimeter and an outer perimeter defining an enclosed geometric shape which extends in a normal state of said gasket within a first plane to a first diametric extent along a first axis, and to a second diametric extent along a second axis disposed within said first plane generally perpendicular to said first axis. The retainer is flexible in the first and second diametric extents within one or more planes generally perpendicular to the first plane. At least one generally annular seal element is supported on the retainer to extend coaxially along at least a portion of the inner or outer perimeter thereof. Each of the seal members has oppositely-disposed first and second radial sealing surfaces configured for abutting, sealing contact with a corresponding one of the interfaces surfaces. With the gasket assembly being interposed between the interface surfaces, each of the seal elements is compressible axially. In such stressed state of the gasket assembly, and with one or more fluid-tight seals being effected between the interface surfaces, the retainer is made to curvably conform to the curvatures of the interface surfaces. However, upon being removed from compression between the interface surfaces, the gasket assembly substantially recovers to its normal state from its stressed state.

A method and system for de-molding golf balls having a casted layer is disclosed herein. The invention includes exerting a first lateral force against a top mold half of a mold assembly and exerting a second lateral force against a bottom mold half of the mold assembly to separate the mold assembly and de-mold the golf balls from the top mold half. Preferably, the mold assembly is used to form a thermoset polyurethane cover over a core and boundary layer. The bottom mold half may have a double tapered pin, or a retractable pin with a single taper. The method and system allow for hot de-molding of golf balls from the mold assembly.

De-molding method and apparatus for a golf ball

A replaceable mold cavity for use in the production of golf balls is disclosed herein. The mold cavity has a plastic insert with an inverse dimple pattern thereon that is formed from a plastic molding material, and a support cup in which the plastic insert is placed for the golf ball molding operation. The plastic insert may have a metal layer thereon that has an identical inverse dimple pattern. The entire replaceable mold cavity may also be composed of a plastic material. The use of plastic molding materials to form the plastic insert, or the entire mold cavity, allows for rapid production of golf balls having different dimple patterns which allows for expedited testing and introduction of new golf balls.
