  • Cutting monofilament
    Patent number: 4172440
    Abstract: Cutting filaments having a long service life consist of a monofilament of a synthetic polymer into which from 0.3 to 10 percent by weight of an abrasive are incorporated. In the cutting process the abrasive is not ripped off, as it does happen with steel wires bearing the abrasive on their surface, but it is pressed into the monofilament and can be easily recovered therefrom.
