Abstract
This rotary cutting head uses relatively short, individually retained, cutting line filaments. It includes, between its periphery and a central recess, at least one radial passageway of cross section corresponding to twice the cross section of a filament. Each filament passes through the corresponding passageway a first time and is folded through 180° in the recess, in order to pass through the passageway a second time, the 180° folding of the filament forming a lateral swelling which ensures its retention.
