Abstract
The invention concerns a cutting wire for trimming and cutting plants useful in appliances with rotary heads, such as bush cutters and hedge trimmers. It has formed shapes of larger cross-section, such as annular shapes, in succession at intervals in the longitudinal direction of the wires, the shapes being separated from one another by intermediate longitudinal sections of the wire, with smaller cross-sections. Such a cutting wire provides operating noise reduction, in particular elimination of squeal and other high pitched sounds.
