ABSTRACT:
A short dwell coater and film applicator coating has an application chamber between an inlet overflow baffle plate and a final metering element. An adjustable wedge is spaced in the machine direction from a fixed wedge to define a gap which serves as a coating extraction port. A cylindrical rod is positioned in the extraction port which is about 3/8th to about two inches in diameter and is driven to rotate at a rate of between one and one-hundred rpm. The rod serves to extract air and coating from the application chamber. Alternatively, an adjustable plate may be positioned to obstruct an opening leading to the extraction port.
