  • the cutting head is provided with several rows of parallel teeth or knives forming fixed the teeth which correspond to the inlet side of each comb may be given la slightly flaring shape, so as to facilitate the penetration and erection of the hairs, as clearly shown by Fig. 4.
  • the various elements of the external combs may be made from a thin steel sheet which is cut, stamped, and folded on itself, forming a double fold between two successive elements, so that the whole may be formed from a single piece which covers the whole of the area of the cutting head.
  • the vertical ribs 6 formed between the teeth of two successive elements constitute rigid supports for the teeth adjacent thereto and increase the rigidity of the whole, at several points intermediate along the width of the cutting head.
  • the latter can therefore be of smaller thickness' and greater area than in the former razors of external combs mounted in a removable manner on the handle 2 of the apparatus.
  • stepped arrangement can be provided only in one direction (Figs. 1 to 9 inclusive) in the case of a shaving apparatus adapted to cut only in one direction, or in both directions (Fig. 10) in the case of a razor adapted to cut in two opposed directions.
  • the teeth of the external combs are arranged in such manner, in the embodiment corresponding to Figs. 3 and 4, as to form steps parallel to this kind and it is possible to adopt a number of steps as high as it is desired, which correspondingly increases the number of inlets and outlets for the hairs. Furthermore, as there remains, as a rule, no space between two successive steps "(excepting the embodiment of Fig. 8) it is possible to take advantage of the whole width of the cutting head' for a satisfactory cutting of the-hairs.
