Abstract: Machine for the deposition, under relative vacuum, of a material on parts (1) in a loose state, comprising a chamber (20, 20') in which there is placed at least one cathode (21, 21') that is negatively polarized with respect to the chamber, and conduits having holes and tubes (11, 12; 11', 12'; 11", 12") for keeping the chamber (20, 20') under a relative vacuum of at least one gaseous agent. The chamber (20, 20') is mounted rotationally about an axis inclined (D, D') with respect to the horizontal inside a housing (10, 10') that carries the relative vacuum, the chamber (20, 20') having an upper aperture (22, 22') for introducing the parts (1) in a loose state and a lower aperture (23, 23') for discharging the parts after the deposition of the material. Application to vacuum deposition techniques.
