  • Patent number: 3999506
    Abstract: Method and apparatus are provided for depositing a coating of uniform thickness across a substrate coated by a vapor-deposition process, for confining and directing the vapor to the substrate in a manner to minimize vapor loss, and for conveniently collecting vapor which bypasses the substrate. A pair of opposed adjustable barrier plates extend transverse to walls defining the path from a vapor source. Means feed a substrate strip in the plane of and between said plates. Condenser rolls overlie the space between corresponding edges of said plates and strip. Means recover coating material condensed into said rolls. Additional means associated with the underside of said strip, disposed transverse to the plate means and external to said walls, further inhibit vapor loss.
