ABSTRACT:
A web to be coated travels over a deflecting roll and underneath a slot nozzle from which a curtain of a coating material falls. A suction box open toward the roll and web has upstream and downstream ends and extends full axial length of the roll. An upstream seal on the upstream side of the box is juxtaposed with the web, extends the full axial length of the roll, and has upstream and downstream edges extending transverse to the web-travel direction. A similar downstream seal is provided on the downstream side of the box juxtaposed with the web. The downstream-seal downstream edge is spaced upstream in the direction from where the curtain falls on the web. Air is withdrawn from the box between the seals to suctionally strip a boundary layer of air from the web between the seals.
