A highly efficient brush device is provided with a plurality of ribbon-shaped bands (3), each one provided with two respective main faces (5) and each one provided with end fringes (7). Each end fringe (7) has at least two main surfaces (9) consisting of said main faces (5), or of extensions thereof, and of two lateral surfaces (11). In a rest condition of a ribbon-shaped band (3), in which it is not assembled with the device (1) and lays flat, the intersections (I1, 12) of at least one geometric plane, which is transversal to at least one end fringe (7), with one of the lateral surfaces (11) and with one of the main surfaces (9) of such at least one end fringe (7) form an interposed angle (A) which is different from 90°.
