Title: METHOD FOR APPLICATION OF A FLUID ON A SUBSTRATE FORMED AS A FILM OR WEB
Abstract:
A method for application of a fluid on a substrate formed as a film or web or laminate in which the substrate is located between two spaced apart electrodes for generating an electrostatic field. An electrostatic field is generated on each side of substrate and a fluid is introduced as droplets for application to the substrate into the electrostatic field on at least one side of the substrate, forming electrostatically charged droplets. The electrostatically charged droplets are directed based upon a predetermined pattern onto the at least one side of the substrate. In accordance with one embodiment, the electrode on the side opposite to the side on which the droplets are introduced is used used to cause the droplets to migrate into the interior of the substrate.
