Coating hoppers are extrusion, slide or curtain. Coating uses a chill cabinet and a series of heating/drying cabinents that condition the film or paper to the proper final conditions. Festooning causes coating defects based on the spacing of the top and bottom rods in the festoon.
AFAIK, EFKE is the only plant that uses festooning outside of the former Soviet Union. IDK about those within it.
