    Abstract: A method of coating a substrate comprises immersing a surface portion of a substrate in a liquid or supercritical first phase. The first phase comprises carbon dioxide and a coating component such as a polymer. The substrate is then withdrawn from the first phase into a distinct second phase such as a gas atmosphere so that the coating component is deposited on said surface portion. The withdrawal step is followed by separating the carbon dioxide from the coating component (e.g., by evaporation, venting, heating, etc.) so that the coating component is retained as a coating layer formed on the surface portion. Apparatus for carrying out the method by free meniscus coating, or employing a metering element such as a knife, blade, or roll, are also disclosed.

    Abstract: An applicator implement applies liquid or pasty coating medium directly onto a moving layer of material, in particular paper or cardboard. The applicator implement includes a pre-metering device which extends along the width of the moving material layer. The pre-metering device is divided into a number of segments, each of which are in turn associated with at least one actuator that enables the segments to move with respect to the thickness of the material layer in order to shape a desired profile of the pre-metering device. The applicator implement further includes, following along the path of movement of the material layer, a finishing metering device which also extends along the width of the moving material layer, and which is divided into a number of segments, each of which are in turn associated with at least one actuator that enables the segments to move with respect to the thickness of the material layer in order to shape a desired profile of the finishing metering device. The widths of the segments of the pre-metering device and the finishing metering device are identical according to a first embodiment or first base model. According to a second embodiment or second base model, the widths of the segments of the pre-metering device and the finishing metering device are not identical.

    Abstract: An application unit for applying a liquid or pasty medium onto a surface moving past the application unit. This has particular application to direct or indirect application of such a medium to a paper or board web. A support beam and a front wall supported generally further from and a rear wall supported generally closer to the moving surface. The walls are spaced apart for defining a pasty medium supply gap between them and are oriented so that the supply gap generally directs the medium toward the surface. The front and rear walls can selectively receive releasable attachment of members for forming a liquid medium an application chamber, the chamber having a downstream end with a blade, an upstream end with a damming strip over which the excessive medium in the application chamber can overflow. Alternatively, a second set of attachable members may be attached to the walls for forming a free jet nozzle dosing gap that communicates with the supply gap for directing the medium to the surface. Therefore, the basic structural group remains unchanged and selectively it may be modified to either an application chamber or a free jet nozzle dosing gap. In an alternate embodiment, the elements defining the dosing gap themselves can receive the attachable elements for defining the application chamber. This enables rearranging the application unit either to define an application chamber or a free jet nozzle with replacement of fewer parts, and generally the parts that are toward the surface.

    Abstract: This invention describes a process and an apparatus for the raster-formed coating of web-shaped flexible flat articles (3) with hot-melt adhesives in a screen printing process by filling all perforations of a rotary screen printing stencil (1) by means of an outer blade (6) with a solution or dispersion of a paste (2), by placing the flat article (2) on the rotary screen printing stencil (1) and by subsequently additionally applying a paste (5) by means of an inner blade (4). On the finished product, paste (2) produces a plastic base layer which is not or only slightly capable of thermal activation and paste (5) produces a hot-melt adhesive top layer which is easily capable of being thermally activated. Following the drying and sintering of the double-layered printed flat article (8), it can be used as an attachable inlay material for items of clothing.

    Abstract: A method of and apparatus for applying coating liquid to a web of paper traveling over a web supporting surface at speeds of 3,000, 4,000 and more feet per minute to produce a coated web free of streaking and other imperfections comprises apparatus for and the sequential steps of distributing coating liquid in a turbulent state over the supported web through a limited application zone within a very short dwell time of the turbulent liquid on the web; subjecting the coating liquid on the supported web to an initial doctoring by means of a primary doctor blade biased under pressure against the coated web at the rear edge of the application zone to form on the web downstream from the zone a relatively quiescent layer of coating liquid having a wet film thickness sufficiently in excess of the final wet film thickness to accommodate a subsequent final wet film doctoring of the coating liquid on the web; and, at a location downstream and isolated from the application zone, subjecting the relatively quiescent layer of excess coating liquid on the supported web to a final doctoring by means of a final doctor blade biased under pressure against the coated web to remove the excess coating from the web and to level and smooth the coating retained on the web to final wet film thickness and smoothness. The method and apparatus of the present invention produces essentially a constant paper smoothness in relation to web speed at which it was coated and subsequently supercalandered, i.e., smoothness does not decrease at higher web speeds, and produces higher gloss with less decline in gloss at higher web speeds.
