METHOD FOR COATING A SUBSTRATE, EQUIPMENT FOR IMPLEMENTING SAID METHOD AND METAL SUPPLY DEVICE FOR SUCH EQUIPMENT

摘要

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.
