Abstract: A method for applying a fluid coating onto a substrate includes forming a fluid wetting line by introducing a stream of fluid onto a first side of the substrate along a laterally disposed fluid-substrate contact area. An electrical force is created on the fluid from an electrical field (originating from electrical charges which are on the second side of the substrate) that is substantially at and downstream of the fluid wetting line. The electrical field can be generated by charges that have been transferred to the second side of the substrate from a remote charge generator.

Abstract: An object of the invention is to provide a method to obtain and keep a uniform charge distribution on a web to be coated at the time of coating to establish stable high-speed coating. It was identified after some research that non-uniform charging is caused by not only non-uniformity at electrifying the web but also leakage of charge to transporting rollers from lateral edge area of the web while the web is transported contacting the rollers. An electrostatic charge on the electrified web leaks from one side surface when the one side contacts the roller and the amount of the leakage depends on a surface resistivity of the surface portion of web. If the leakage happens from a back surface (surface usually not to be coated), which causes leakage from a front surface area (surface to be coated) corresponding to the back surface area where the leakage happened. Thus it is understood that web of which back surface has higher resistivity in the edge area than that in the central area is useful for stable coating using electrified web. One of ways to provide higher surface resistivity to either both edge areas or one edge area is to apply a subbing layer to the web to leave the edge area unapplied.

Abstract: In the method for curtain coating a moving support with any kind of coating solution, the air which is carried along by the moving support is extracted in front of the curtain as seen in the running direction of the support in a gap which extends concentrically to the support, and air is continuously supplied in a controlled manner. In the process, the supplied air is regulated in function of the extracted air in such a manner that a parabolic velocity profile develops which comprises a point P at a distance d from the support where the air velocity is equal to zero. In the device implementing the method, this adjustment is essentially enabled by a porous layer which is disposed on the support side in a cavity to which a suction resp. an air supply channel is connected. In this manner, a uniform coating of high quality can be obtained.

Abstract: A method and apparatus for preventing vortical air flow behind a free-falling curtain in a curtain coating apparatus. There is a critical region within the coating apparatus defined in part by a coating hopper, the free-falling curtain delivered from the coating hopper, a portion of the moving substrate supported on a roller to which the free-falling curtain is delivered, and an air shield located between the roller and the coating hopper. A first intake slot proximate to the moving substrate shield is used to remove boundary-layer air entrained on the moving substrate. A second intake slot positioned within the critical region is used to remove boundary-layer air entrained on the free-falling curtain. Each of the two intake slots is connected to vacuum source. One or two vacuum sources may be used.

Abstract: A system for coating a substrate with an ultra-thin layer includes moving the substrate through a coating station and forming a composite layer including a coming fluid and a carrier fluid. The composite layer flows at a rate that is sufficiently high to form a continuous flowing fluid bridge of composite layer to the substrate surface and to contact the substrate with the flowing composite layer to interpose the coating layer between the substrate and the carrier fluid. The carrier fluid is removed while leaving the coating fluid deposited on the substrate as a coating layer.

Abstract: A method of curtain coating that applies a free falling curtain of liquid coating composition onto a running support is disclosed. In the method, the sides of the support parallel to the running direction of the support are bent downwardly before the curtain is applied, and thus are not coated, and are subsequently unbent.
