发明名称 A vegetation cutter including a cutting filament
摘要 The invention is directed to a cutting filament for a vegetation cutter. The vegetation cutter includes a drive motor which sets the cutting filament in motion thereby producing noise. The cutting filament extends substantially radially outwardly because of the centrifugal force. The cutting filament reduces noise especially at high rotational speeds and thus also at high peripheral speeds. This is achieved in that the cutting filament is configured to have a cross section not having point symmetry. The cutting filament preferably has at least one slot and/or protrusion formed in the surface thereof to extend in the longitudinal direction. The slot and/or protrusion can, for example, be formed so as to follow a helical path with respect to the longitudinal axis of the filament or it can extend parallel to this axis.
