Devices and methods for applying liquid coatings to substrates |
摘要 |
Liquid film dies for coating of substrates with thin films of fluid have substantially constant fluid path geometry fluid passages leading to fluid outlet orifices. A fluid film applicator for applying a film of a fluid onto a substrate includes a dispensing head which dispenses the fluid so that the fluid is deposited as a continuous sheet on the substrate, and a meniscus forming member that controls the thickness of the fluid in the continuous sheet. The dispensing head may include upper and lower plates with a fluid channel between, the plates being offset and positioned relative to the meniscus former. A variable contour dispensing head has movable dispensers which feed coating fluid to a common slot, and the slot can be deformed to correspond to the shape of the surface being coated.
