The method for manufacturing a makeup brush includes: molding a ferrule and welding bristles to the ferrule. The ferrule includes a ferrule inner end; a ferrule outer end; a ferrule body; an interior; and a well. The well has a well base parallel to the ferrule outer end. The well base has an inner side and an outer side. The step of welding the bristles includes the steps of disposing the bristles in contact with the outer side of the well base and exposing the inner side of the well base to welding.

The invention concerns a dish brush (1, 11) for conventional sweeping machines for cleaning, brushing or sweeping paved surfaces, wherein special constructed sweeping elements (4) and steel cable plugs (5) both waste and weeds remove from different types of paved surfaces. The mentioned sweeping elements (4) are fastened with welds (8,9) from the top side of the raised contour edge (2) through slit openings (6,7) and the steel cable plugs (5) are fastened with a weld (10) from the bottom side of said contour edge (2). The advantage is a well applicable sweeping and weeds removing dish brush (1,11) and which can be manufactured in a very economical way.
