A method and apparatus for vapor depositing a release agent on a foil. The foil is wrapped around a cylindrical drum which is made of a porous material. The hollow inside of the drum forms a vapor space. The outer surface of the drum includes a thin metallic layer which has engraved or etched therein a pattern of surface passages. A vaporizer vessel provides a vaporized release agent which is conducted to the vapor space inside the drum. The release agent travels through the circumferential passages so as to be deposited in a pattern on the foil which is wrapped around the drum. A conforming body covers the circumferential surface not covered by the foil and can be heated to heat the drum.

Vapor deposition apparatus

A metallizing device for vacuum metallizing arrangements is disclosed having a vaporizer (,) heated by an electrical heating rod (,). This vaporizer (,) is connected to a nozzle element (,) in the form of a hollow body. For the purpose of vaporizing a substrate, vapor flows out of the vaporizer (,) into the nozzle element (,) and from there out of a nozzle gap (,) toward the substrate.
