Description

ABSTRACT:
Pond pressure controlling device, e.g. a tiltably mounted metering lip baffle is mounted on the floor area which in part defines with an upstanding doctor blade and rib running on the backing surface roll a coating application pond chamber, provides an adjustable output orifice for the chamber spaced from the blade at an upstream location relative to the direction of travel of the web. A pressure fluid responsive device, e.g. an inflatable bladder, is adapted for selectively adjusting the pond pressure controlling lip baffle for obtaining a desired output orifice dimension. In another form the controlling device may comprise simply an inflatable tubular bladder mounted on the floor area provided with any adjustable orifice-defining rib.
