Abstract
A discrete cutting element (18) including a plurality of cutting filaments (26) for use in a vegetation line trimmer (10). In a preferred embodiment provided filaments (26) emanate from a common locus (27) at a filament holder (16) for rotation about the holder's axis of rotation. Certain embodiments can include axially fixed apparatus for conducting the associated filaments (26) away from a spool-like member (23) around which the filaments (26) are wound, and aiding divergence of the filaments.
Claims11
A cutting assembly for use in a vegetation line trimmer, comprising:
- a filament holder mounted to the vegetation line trimmer for rotation about an axis;
- and
- a plurality of associated cutting filaments the free ends of which emanate from a common situs at the outer surface of said filament holder, said plurality of filaments disposed for radial extension from said outer surface when said filament holder is made to rotate about said axis.
In a vegetation line trimmer of the type in which a line cutting element is mounted for rotation about an axis to define a cutting path, an improved cutting assembly, comprising a cutting element having a plurality of associated discrete cutting filaments, source ends of each of said filaments extending radially from a common angular locus spaced from said axis, to cooperate with one another in operation in the cutting of vegetation.
