Abstract: An emulsion coater apparatus for filling a screen with emulsion is described. A head delivers pressurized emulsion onto and through holes in a screen. Squeegees located on either side of the screen are then drawn across the screen's surface so as to remove excess emulsion and fill any holes not filled by the high pressure head. The emulsion coater apparatus coats a screen in a single pass, thus making the coating process more efficient. Moreover, dispersing emulsion under pressure alleviates the need to degrease the screen, saving costs and minimizing environmental damage.
