Abstract: The invention relates to a vapour generator for the deposition of a metal coating onto a substrate (7), preferably a steel strip, that comprises a vacuum chamber (6) in the form of a housing including a vapour deposition head or ejector (3) in tight communication via a supply duct (4) with at least one crucible (1) containing the coating metal in a liquid form and located outside the vacuum chamber (6), characterised in that the ejector (3) includes a longitudinal slot for the vapour outlet acting as a sonic throat and extending on the entire width of the substrate (7), a filtration medium or a charge loss member (3A) made of a sintered material being provided in the ejector immediately before said slot on the vapour path in order to equalise the flow speed of the vapour exiting the ejector (3) through the sonic throat.

Abstract: A vacuum deposition facility 1 for continuously depositing, on a running substrate S, coatings formed from metal or metal alloy, the facility including an evaporation crucible 4 suited to supply metal or metal alloy vapor and including an evaporation pipe 7, a deposition chamber 2 suited to have the substrate S run through along a given path P and a vapor jet coater 3 linking the evaporation pipe to the deposition chamber, wherein the vapor jet coater further includes a repartition chamber 31 including at least one reheater 33 positioned within the repartition chamber and a vapor outlet orifice 32 including a base opening linking the vapor outlet orifice to the repartition chamber, a top opening through which the vapor can exit in the deposition chamber and two sides converging toward each other in the direction of the top opening.

Abstract: A vacuum deposition facility for continuously depositing, on a running substrate, coatings formed from metal or metal alloy, the facility including—a vacuum chamber and a device for running the substrate through the vacuum chamber along a given path, wherein the vacuum chamber further includes: a central casing including a substrate entry and a substrate exit located on two opposite sides of the central casing and a vapor jet coater, the inner walls of the central casing being suited to be heated at a temperature above the condensation temperature of the metal or metal alloy vapors, a vapor trap in the form of an external casing located at the substrate exit of the central casing, the inner walls of the vapor trap being suited to be maintained at a temperature below the condensation temperature of the metal or metal alloy vapors.
