Abstract: A methods, apparatus and compositions for producing colored, self-cleaning substrates by roll coating are provided. The roll coated, colored, self-cleaning substrates retain the predetermined color and a predetermined gloss of the colored coating, thereby facilitating their use in architectural applications. The roll coated, colored, self-cleaning substrates may be iridescent-free.

Abstract: A method of creating a fluid layer in the micrometer range includes transferring a fluid between substrates and forming a fluid layer. A surface energy of a first substrate releasing the fluid is higher than a surface energy of a fluid on the first substrate to create a first fluid deposit on the first substrate. A surface energy of a second substrate accepting the fluid is lower than a surface energy of a fluid on the second substrate to create a second fluid deposit on the second substrate that is reduced as compared to the first fluid deposit. A surface energy of a third substrate accepting the fluid is higher than a surface energy of a fluid on the third substrate to create a substantially homogeneous third fluid deposit on the third substrate that forms the fluid layer.

Abstract: A device for applying a suspension to which particles, in particular corundum particles, have been added onto a base plate, with a roller mill comprising an applicator roll and a metering roll interacting with the applicator roll. An application groove with two groove halves project laterally and tilt downwards at an angle a to the horizontal with slots on the base side arranged above the roller mill.

Abstract: A method and system for coating a vinyl workpiece includes denibbing the workpiece and deionizing the air around the workpiece. The workpiece is roll coated using a roll coating machine, wherein the roll coating machine includes a plurality of engraving rollers. An angular surface of the workpiece is roll coated using a corresponding angularly positioned application roller. The workpiece is coated with an ultraviolet (UV) curable coating using a vacuum coating machine. The UV coating is cured using the vacuum coating machine.

Abstract: In a display manufacturing method including bonding of a light-transmissive substrate onto a display surface of a display body, the bonding includes bending the light-transmissive substrate into an arch-like shape with a bonding surface thereof having a convex shape. An adhesive sandwiched is put between a bonding surface of the display body and a top of a bonding surface of the bent light-transmissive substrate. The bend of the light-transmissive substrate is released while moving two rollers from a center of the light-transmissive substrate in a direction of the bend of the light-transmissive substrate towards both terminal edges of the light-transmissive substrate in mutually reverse directions. The two rollers press a non-bonding surface of the light-transmissive substrate against the display body.

Abstract: A plurality of gravure rolls are rotated while being allowed to abut against a surface of a moving electrode hoop, thereby applying a coating fluid serving as a precursor of porous layers onto a plurality of linear mixture layers. In this way, a plurality of linear porous layers are formed on the associated linear mixture layers formed on the surface of the electrode hoop. In this case, the location at which each gravure roll abuts against the surface of the electrode hoop is controlled according to variations in the lateral location of associated one of the mixture layers independently of the other gravure rolls.

Abstract: A method for producing a lenticular material having a predetermined surface characteristic of high quality and definition formed on one side thereof is disclosed. The method includes the steps of providing a rotating, engraved cylindrical roll, advancing a material along a predetermined path of travel while directing one surface of the material into contact with a peripheral surface of the rotating, engraved cylindrical roll, applying to the peripheral surface of the roll a coating of a uncured resin, such that the coating is located about the roll and beneath the material, controlling the thickness of the coating, curing the resin coated about the material, and directing the material with the cured resin thereon away from the rotating cylindrical roll.

Abstract: The invention relates to a coating device (10) comprising a coating tank (21) with an opening (22) and a coating roll (31), in which the roll (31) faces the opening (22). A further subject of the invention is a method for coating a substrate with a fluid comprising the steps of (i) supply of a substrate (40) and of a fluid, (ii) application of the fluid to the substrate (40) and (iii) shearing of the fluid by the substrate (40) set in motion in relation to the fluid.

Abstract: The present invention is directed to methods, processes, and systems for roll coating portions of a workpiece as well as to workpieces that have themselves been roll coated in accord with the invention. Under these methods and processes of the invention, one of a roller and/or the workpiece may be moved longitudinally to apply coating to a target surface of a workpiece. In some embodiments, a plurality of rollers may be used and supported by arms. Still further, in accord with the embodiments of the present invention, a dispensing member may be provided to fluidly connect the roller with a reservoir. In still other embodiments, the workpiece may be an implantable medical device and the coating may include a therapeutic.
