  • Process for forming double-strand edged monofilament line for use in line trimmers
    Patent number: 6124034
    Abstract: A process for forming flexible cutting line for use in rotary vegetation trimmers of the type having two or more monofilament lines mounted on a common spool. The line produced by the process of the present invention defines two monofilament strands joined together in a side-by-side relationship by a severable bond. Each strand defines a plurality of circumferentially spaced and outwardly projecting vegetation cutting edges thereon, two of the edges on one of the strands being in parallel contact with two of the edges on the other strand so as to define a pair of parallel readily severable welds bonding the strands together in a side-by-side disposition.
    Type: Grant
