ABSTRACT:
A thin metal layer is applied in a thickness of less than 1,000 nm to a polymeric, web-like substrate which is moved along a cylindrical support in a vacuum chamber containing an evaporator crucible releasing the metal vapor toward the support and two coating screens arranged between the evaporator crucible and the support and defining the limiting angles of incidence of the vapor jet striking the substrate, by a process in which, in the case of predetermined limiting angles of incidence, the amount of metal vapor applied to the substrate can be optimized by means of the arrangement of the coating screens and the position of the evaporator crucible.
