Abstract

In a method for coating strip material by means of an electron beam line evaporator, deflecting in a time-invariant program the electron beam to a plurality of dwell points arranged along a path normal to the direction of strip travel, sensing film thickness in a time-variant programmed mode at a plurality of positions arranged along a course normal to said direction of strip travel and subsequent to said path in said direction of strip travel, controlling in accordance with said programmed mode the dwell of said electron beam at selected dwell points to provide uniform film thickness distribution on said strip.
