Curtain coating is a process that creates an uninterrupted curtain of fluid that falls onto a substrate. The substrate is transported on a conveyor belt at a regulated speed through the curtain to ensure an even coat of the die. The curtain is created by using a slit at the base of the holding tank, allowing the liquid to fall upon the substrate. Most manufactures will also include a catch pan to retrieve and reuse the excess fluid.

Famous quotes containing the words curtain and/or coating:
“Once the curtain is raised, the actor ceases to belong to himself. He belongs to his character, to his author, to his public. He must do the impossible to identify himself with the first, not to betray the second, and not to disappoint the third.”
—Sarah Bernhardt (1845–1923)
“The world is eaten up by boredom.... You can’t see it all at once. It is like dust. You go about and never notice, you breathe it in, you eat and drink it. It is sifted so fine, it doesn’t even grit on your teeth. But stand still for an instant and there it is, coating your face and hands. To shake off this drizzle of ashes you must be for ever on the go. And so people are always “on the go.””
—Georges Bernanos (1888–1948)
