ABSTRACT:
An apparatus for successive application of two coats of at least one coating medium on one side of a traveling fiber material web includes a rotating backing roll and a first rotating applicator roll having a roll surface. The first applicator roll and the backing roll define a first press nip therebetween. A first applicator assembly is positioned in association with said roll surface for applying a first coating medium to the roll surface. The first applicator assembly and the first applicator roll conjunctively define a first indirect applicator for applying the first coating medium to a first side of the fiber material web. A first drying apparatus is positioned after the first press nip relative to a direction of travel of the fiber material web. The first drying apparatus is positioned in association with the first side of the material web. A second applicator is positioned after the first drying apparatus relative to the direction of travel of the fiber material web. The second applicator is also positioned in association with the backing roll whereby the traveling fiber material web travels between the second applicator and the backing roll. The second applicator is configured for applying a second coating medium to the first side of the fiber material web.
