Abstract

Abstract Vacuum metallizing apparatus wherein metal contained in a crucible in a vacuum chamber is melted to form vapor adapted to metallize a continuously moving web of sheet material with metal vapor as it moves therepast and having means to direct such vapor only onto preselected portions of the web, such means including a vapor masking means positioned between the crucible or vapor supply source and the web and consisting of a heat conductive frame having slots therein for receiving vapor masking ribs (of various shapes), which ribs are slidably positioned in thermal contact with the frame, in the slots. The frame is cooled by cooling means connected to it, which cooling means also cool the masking ribs of the vapor masking means by reason of the thermal contact between the frame and the ribs. Connecting material may be inserted between the ribs and the surface portions of the frame defining the slots to thermally connect the ribs to the cooling means.
