Process
Curtain Coating is a process in which the object or substrate to be coated is guided through a curtain of fluid located in a gap between two conveyors. The mechanism is formed by a tank of fluid from which a thin screen falls down in between the two conveyors. The thickness of the coating layer that falls upon the object is mainly determined by the speed of the conveyor and the amount of material leaving the tank (Pump Speed). Curtain coating is a premetered method, which means that the amount of liquid required is supplying from the tank to the screen in order to be deposited on the substrate.
Curtain coating is one of the technologies used in the converting industry to modify the properties of substrates.

Famous quotes containing the word process:
“When you start with a portrait and search for a pure form, a clear volume, through successive eliminations, you arrive inevitably at the egg. Likewise, starting with the egg and following the same process in reverse, one finishes with the portrait.”
—Pablo Picasso (1881–1973)
“A process in the weather of the world
Turns ghost to ghost; each mothered child
Sits in their double shade.
A process blows the moon into the sun,
Pulls down the shabby curtains of the skin;
And the heart gives up its dead.”
—Dylan Thomas (1914–1953)
“It is part of the nature of consciousness, of how the mental apparatus works, that free reason is only a very occasional function of people’s “thinking” and that much of the process is made of reactions as standardized as those of the keys on a typewriter.”
—John Dos Passos (1896–1970)
