In order to provide a rotating trimming line (10) for brush cutters (100) equipped with a driving motor (119) which sets the rotating trimming line (10) that is clampingly secured with one end (13) into rotational movement, in which case the rotating trimming line (10), by virtue of the centrifugal force, extends essentially toward the outside and the rotating trimming device (10) is constructed in such a way that, in relation to its longitudinal axis (L), it possesses a varying position of the cross-section, with which, even at a high speed of rotation or at a high number of revolutions per unit time of the rotating trimming line, a substantial noise reduction can be achieved in comparison with the known rotating trimming line embodiments, which is simple to manufacture and which possesses a great stability, it is proposed that the rotating trimming line (10) possesses a radially symmetrical, viz. a polygonal, cross-section (Q, Q1, Q2, Q3), that the cross-section (Q, Q1, Q2, Q3), in relation to the longitudinal axis (L), is constant and that the position of the cross-section, in relation to the longitudinal axis (L), varies continuously by a constant angular amount per unit of length of the longitudinal axis (L).
