  • Process for making integrated racket strings from monofilaments
    Patent number: 4288977
    Abstract: The quality of a resin-bonded twisted string comprised of three flattened monofilaments in a side-by-side relationship is improved when the monofilaments are precoated with resin prior to twisting and then twisted in a zone wherein the excess lengths of the two outer monofilaments in the twisted configuration is compensated for during twisting by forwarding the two outer monofilaments at a positively controlled speed and allowing the speed of the middle monofilament to be controlled by being drawn into the twisting zone through a roller slot guide at a speed freely determined relative to the speed of the two other monofilaments entering the twisting zone.
