    Abstract: A method of coating a travelling web with at least one layer of a liquid coating composition, includes the steps of moving the web along a path through a coating zone and forming at the coating zone a free-falling vertical curtain which extends transversely of the path and impinges the travelling web to deposit thereon a coating. The free-falling curtain is composed of at least two separately formed free-falling partial curtains which are joined edge to edge, one partial curtain constituting an edge region of the integral curtain and the other or others constituting a central region and another edge region of the integral curtain.

    Abstract: In a method of coating a support with a liquid coating composition in which the coating composition is applied by impingement of a free-falling curtain of coating composition onto the surface of the moving support, formation of edge beads along the edges of the coating which are of greater thickness than the remainder of the coating is effectively avoided by use of laterally adjustable edge guides which are initially positioned so as to establish a stable free-falling curtain and then moved laterally to a position in which they are slightly further apart, whereby the coating assumes a uniform thickness. The method of this invention is useful in both single-layer and multiple-layer curtain coating and are especially advantageous in the manufacture of photographic film and photographic paper in view of the need for precisely uniform thickness over the entire coated area.
