NOISE ATTENUATING FLEXIBLE CUTTING LINE FOR USE IN ROTARY VEGETATION TRIMMERS AND METHOD OF MANUFACTURE

A noise attenuating cutting line (10) for use in rotary vegetation trimmers formed by a pair of molten monofilament strands (10a, 10b) in proximate disposition through a rotating die (40) so as to form a line comprised of two monofilament polymer strands bonded together in a twisted disposition abou...

Zusammenfassung:	A noise attenuating cutting line (10) for use in rotary vegetation trimmers formed by a pair of molten monofilament strands (10a, 10b) in proximate disposition through a rotating die (40) so as to form a line comprised of two monofilament polymer strands bonded together in a twisted disposition about a central longitudinal axis so as to define a pair of substantially V-shaped opposed troughs (12a, 12b) extending helically along and about the line.
