  • Patent number: 8201299
    Abstract: A tool for cleaning surfaces, comprising a body with a substantially cylindrical shape, on a face of which there are distributed along at least a path clumps of bristles inserted into corresponding holes made on said face, the axis of each of said holes is inclined in relation to a perpendicular to the surface of said face, on a plane substantially tangential to said at least a path, or on a plane substantially radial to said path, or on both said planes.
    Type: Grant

  • Publication number: 20050081316
    Abstract: A roller for rotating cylindrical brushes that can be applied in any industrial, road-related or other sector, of the kind constituted by a central support, on the outer surface of which a plurality of holes for inserting and fixing respective tufts of bristles are distributed with a constant spacing, the support being constituted by at least one cylindrical ring and the holes being arranged on planes that are perpendicular to the axis of the roller and are successively and alternately inclined on either side with respect to planes that are radial or parallel to radial planes that pass through the axis of the cylinder and through the respective hole in order to sweep, with the ends of the bristles, two bands arranged laterally to the row of tufts.

  • Publication number: 20020189043
    Abstract: A modular roller for industrial rotary cylindrical brushes, particularly for outdoor use, of the type constituted by a central support in which a plurality of tufts of bristles are fixed, the support being constituted by a cylindrical ring whose faces are cut along two mutually parallel planes that are inclined with respect to planes that are perpendicular to the direction of the axis of the cylindrical ring, the tufts of bristles that are distributed along the ring lying on planes that are substantially radial with respect to the ring and parallel to the inclined planes of the faces.
