The invention relates to a method for coating at least one surface of a running substrate by the vacuum evaporation of a metal or metal alloy layer that can be sublimated, wherein the metal or metal alloy is provided opposite the surface of the substrate in the form of at least two ingots in contact with each other, the surface of the ingots oriented towards the substrate surface being held parallel to the substrate at a constant distance therefrom during the coating process; the invention also relates to a coating equipment for implementing said method and to a metal supply device (1) for such an equipment.
L'invention concerne un procédé de revêtement d'au moins une face d'un substrat en défilement, par évaporation sous vide d'une couche de métal ou d'alliage métallique susceptible d'être sublimé, selon lequel le métal ou alliage métallique est disposé en regard de la face du substrat sous la forme d'au moins deux lingots placés en contact l'un avec l'autre, la surface des lingots tournée vers ladite face du substrat étant maintenue parallèle au substrat et à une distance constante de celui-ci, au cours du revêtement, ainsi qu'une installation de revêtement pour la mise en AEuvre du procédé et un dispositif d'alimentation en métal (1) pour une telle installation.
