Abstract
Barrier coatings are deposited onto fibrous materials at atmospheric pressure by a continuous CVD process. A relatively short furnace tube with an unrestricted outlet is used. Thus, the supply and takeup reels do not need to be contiguous with the coating part of the apparatus. This allows the periodic removal of fuzz and soot without the interruption of the coating process.
