Abstract: Coating apparatus (20) includes a pair of juxtaposed bodies (22, 24, 112, 114, 112a, 114a, 138, 140) defining a nip region (30, 126, 126a, 150) therebetween, with each presenting a periphery (26, 28, 116, 118, 116a, 118a, 144, 146) and being rotatable in opposite directions, respectively. The peripheries (26, 28, 116, 118, 116a, 118a, 144, 146) of the bodies (22, 24, 112, 114, 112a, 114a, 138, 140) are provided with a series of indentations (32, 120, 120a, 148). Liquid coating material is directed onto the bodies (22, 24, 112, 114, 112a, 114a, 138, 140) through an outlet (100, 110, 158) during rotation of the bodies (22, 24, 112, 114, 112a, 114a, 138, 140). This generates an adjustable spray or fog flow pattern (108) for effective coating of a substrate.

Abstract: Coating apparatus (20) includes a pair of juxtaposed, cylindrical bodies (22, 24) defining a nip region (30) therebetween, with each presenting a periphery (26, 28) and being rotatable in opposite directions, respectively. The peripheries (26, 28) of the bodies (22, 24) are provided with a series of laterally extending notches (32), optionally oriented to provide chevron patterns (68) with apices (32a) and diverging legs (70a, 70b); the patterns (68) are positioned so that the apices (32a) first pass through the nip region (30), with the legs (70a, 70b) in trailing relationship. Liquid coating material is directed onto the bodies (22, 24) through an outlet (100, 110) during rotation of the bodies (22, 24). This generates an adjustable spray or fog flow pattern (108) from the apparatus (20) for effective coating of a substrate.
