Abstract
The process according to the invention comprises twisting a plastically deformable wire, typically of metal, so that it imprisons fibers within it, with the parts of the fibers projecting from the wire forming bristles in a helicoidal spiral, and of shaving off some of the bristles in predefined angular sectors by using the twisted wire to guide the components causing the total or partial ablation of the bristles.
