  • Publication number: 20140076487
    Abstract: A method of forming a flexible implement grip utilizing a cured underlist. A sleeve is formed of uncured sheet stock laminated with a carrier having a design thereon of heat transferable colored ink. The laminate is cut to a pattern, wrapped on a core bar and heated in a mold with textured/embossed cavities. The design is heat transferred to the sheet stock in the molding and upon removal from the mold, the carrier and core bar are removed to leave a seamless tubular sleeve with the colored design on the outer surface. The sleeve is then assembled on the underlist and adhesively secured thereon forming a finished grip.

  • Publication number: 20130248089
    Abstract: In one version of the method of making a flexible grip, a thin film carrier with negative of desired colored image is laminated to an uncured skin sheet and flat cured in a mold to heat transfer the image to the skin sheet and concurrently form a textured surface. The carrier is peeled away and the skin sheet wrapped and adhesively bonded to a cured underlist. In another version, the thin film carrier with negative of desired image is laminated on an uncured skin sheet which is wrapped on a cured underlist. The wrapped underlist is cured in a textured mold cavity to concurrently, in a single molding operation, heat transfer the image of the skin sheet from a textured surface and cure the skin sheet in place on the underlist.
