  • Process for fabricating false eyelash system
    Patent number: 5547529
    Abstract: The invention is a false eyelash system, for producing unknotted clusters of false eyelashes from long fibers. A plurality of long fibers are knotted around a main string with a preliminary knot. The long fibers are trimmed a distance away from the main string that corresponds to a desired eyelash length. Cement is applied to the preliminary knot and discernible distance therefrom to form a cement clot. The preliminary knot is removed by cutting through the cement clot to form unknotted clusters of false eyelashes.
