Abstract (en)
[origin: WO9211572A1] Described herein is method for coating a support (14, 14'), such as a web of paper or film, with a liquid composition, such as photographic emulsion. The support is moved through a coating zone and a moving sheet (32, 134) of the composition is directed at the support. The moving sheet may be a falling curtain (32) or it may be formed by an extrusion die with the sheet directed other than vertically. The sheet and the support are positioned relative to one another so that the sheet impinges on the support in the coating zone with an acute angle between the sheet and the uncoated support and so that the angle between the plane of the sheet just prior to infringement and a plane tangential to the support at the line of impingement of the sheet on the support is A DEG which lies in the range of 30 DEG to 60 DEG . It is ensured that the liquid in the sheet has a speed just before impingement on the support of at least 200 cm per sec.
