Abstract (en)
[origin: US6468592B1] A web is coated by passing it in a horizontal web travel direction beneath a slot nozzle extending transversely of the direction. A pigment-carrying liquid is ejected at a flow speed from a slot of the nozzle to form a downwardly free-falling curtain extending across the web. A vertical inner face of a guide element is oriented at each outer edge of the curtain with each face extending from a respective end of the slot downward to adjacent the passing web. An upper region of each of the inner faces is fed is to a respective partial stream of the liquid such that the partial streams flow down the respective inner faces at a speed at least equal to the curtain flow speed and merge with the outer edges of the curtain.
