S p e c i f i c a t i o n TITLE OF THE INVENTION Vacuum Evaporation Equipment ABSTRACT OF THE DISCLOSURE A vacuum evaporation equipment for continuous vacuum evaporation of a metal onto a band or hoop of product including at least one vacuum sealing station, is improved by the provision of duct means that are disposed surrounding the band product and extending from the point of vacuum deposition where the band product is subjected to vacuum evaporation process to a chamber held at a reduced pressure or vacuum state to an extent that substantially no reevaporation of once deposited metal is effectively prevented from occurring, and that are adapted to be heated to a point substantially higher than the temperature of said steel band product. In addition, there is attained a further improvement of a vacuum evaporation equipment for continuous vacuum evaporation of a metal onto a band product including at least one vacuum sealing station, roll means mounted rotatably in the interior of a casing and complementary cover means mounted in a complementary engagement relationship with the roll means at a close gap therebetween, which comprises side panel means mounted self-adjustably in sliding motion in the longitudinal direction along the axes of the roll means on the opposite ends thereof, and heater means mounted adjacently and operatively to heat the roll means and complementary cover means.
