  • Cutting line with improved degradability for brush cutters and edge trimmers
    Patent number: 6061914
    Abstract: This cutting line intended to trim and cut vegetation can be used in rotary-head implements such as brush cutters and edge trimmers. The cutting line consists of a core made of biodegradable and/or photodegradable substance which is covered with a coating or "skin" made of a synthetic substance such as polyamide or polyurethane, forming the exterior surface of the line. Such a line can thus be broken down more rapidly after use, while at the same time retaining excellent mechanical qualities while it is being used.
