ABSTRACT OF THE DISCLOSURE A moving substrate material (12) such as a web of piper, paper- board, film, or other substance is covered with a coating by propel- ling a coating material (38) onto a deflector bar (39) positioned near the substrate material. The deflector bar (39) is configured to de- flect the coating material (38) toward the moving web in a continuous, free standing, smooth jet curtain (40) of coating material. The coat- ing on the web is free of skips, scratches, and other imperfections. In one embodiment, propulsion of the coating material toward the bar (39) is accomplished by rotating a drum (22), or applicator roll, through the coating material. The surface of the drum (22) or roll carries the material to the deflector bar (39) at a speed and in a sufficient quantity to cause the material to be deflected by the bar (39) in a continuous free standing curtain (40) toward the paper web.
