Abstract:
A manufacturing process for making a mascara brush comprising:providing at least one cutting tool with a blade;providing bristles;providing at least one plastically deformable wire, the wire having two branch;positioning the bristles parallel to one another, shifting longitudinally and between the two branches of at least one plastically deformable wire, the bristles being approximately perpendicular to the wire, the bristles and wire forming a brush;providing a tube that defines multiple, narrow, longitudinal bores that select bristles with an angle beta that correspond to a sector in which ablation of the bristles occurs. the tube having an inner diameter that is greater than a diameter of the plastically deformable wire and smaller than the outer diameter of the brush, the tube having a symmetry that permits application of the cutting tool to the bristles of the brush;deploying the tube in such a way as to bend the bristles, forming bent bristles, and to bend the center of the brush;cutting the bent bristles with the cutting tool so that the cutting tool is guided by the twisted wire wherein bristles of the brush are shaved off; andtwisting the plastically deformable wire so as to form with the bristles a helicoidal spiral, characterized in that the spiral includes a partial or total ablation of the bristles in angular sectors of the helicoidal spiral formed by the bristles (5) by the horizontal motion of at least one cutting component.
