Vacuum deposition apparatus used for coating films by condensation of the metal vapor has a gas lance for guiding a cooling gas stream against the film arranged in the winding chamber approximately over the width of the film
A gas lance (15) for guiding a cooling gas stream against the film is arranged in the winding chamber approximately over the width of the film. Vacuum deposition apparatus comprises a roller (10) with a partial region of its sleeve surface inserted in a winding chamber (4) held under vacuum and a vacuum deposition chamber (3). A film (9) to be coated is lead out of the winding chamber along a partial region of the sleeve surface of the roller through the deposition chamber and back to the winding chamber. A gas lance (15) for guiding a cooling gas stream against the film is arranged in the winding chamber approximately over the width of the film. An Independent claim is also included for a process for the coating a film using the above vacuum deposition apparatus.
