ABSTRACT:
Production of a longitudinally striated coating on a strip article by advancing the article past an open side of an otherwise-enclosed trench so that the article surface to be coated closes the open trench side, while delivering concurrent laminar flows of two different liquid coating materials to the trench at least at one locality spaced from the trench open side, to keep the trench completely filled and to deposit a layer of coating material on the moving article surface. Liquid circulation in the trench caused by the motion of the article surface so distributes the two coating materials along the trench that the applied coating layer is constituted of alternating longitudinal striations of the two materials. With delivery of concurrent flows of the two coating materials at each of plural localities spaced along the trench, positional and other variations of the striations can be achieved by varying the relative total flows delivered at different ones of these localities, for example to create a simulated wood-grain pattern.
