<p>The subject of the invention is a head for cutting hair in the nose and ears without making the blades come into contact with the skin. The technical problem consists in the difficulty of making a closed crown of very small diameter (around 9 millimetres) with numerous openings for the hair to enter. With a crown 2 millimetres wide, the internal diameter is 5 millimetres with openings of around 0.3 millimetres and shoulders around 0.6 millimetres, if there are only 16 openings. The solution consists in making, on the shoulders of the outer diameter (approximately 1.4 millimetres wide), another series of openings, yet limiting their length so as not to reach the shoulders at the internal diameter and therefore not weaken them. The result is a doubling of the openings and of the entries for hair on the external diameter, while maintaining the necessary mechanical strength. <IMAGE></p> |
