An apparatus and method of applying a finish or paint coating in a prefinishing or finishing line to a fencing panel or picket that disguises the screen-back texture of the engineered wood substrate. After paint or similar coating is applied (such as by one or more spray nozzles) to a face to a fence picket or fencing product or component, the fence picket passes under a roller, brush, or roller brush or similar paint applicator while the paint is still wet. The roller/brush removes some of the paint and applies an angled pattern to the face, which disguises the screen-back texture of the substrate.

The present invention generally relates to a device and a process for performing large-scale noncovalent functionalization of 2D materials, with chemical pattern elements as small as a few nanometers, using thermally controlled rotary Langmuir-Schaefer conversion. In particular, the present invention discloses a device comprising a thermally regulated disc driven by a rotor with fine speed control configured to be operable with a Langmuir trough for performing large-scale noncovalent functionalization of 2D materials, achieving ordered domain areas up to nearly 10,000 m.sup.2, with chemical pattern elements as small as a few nanometers. A process using the device for performing large-scale noncovalent functionalization of 2D materials with chemical pattern elements as small as a few nanometers is within the scope of this disclosure. The process we demonstrate would be readily extensible to roll-to-roll processing, addressing a longstanding challenge in scaling Langmuir-Schaefer transfer for practical applications.

The present disclosure provides a coating method for suppressing variations in a coating amount, a coating apparatus and a method for manufacturing a component. A coating method is employed, which includes: discharging a coating needle adhering to an adhesive from a nozzle; separating the adhesive into the tip of the coating needle and the nozzle; and adhering the adhesive to a first member. A coating apparatus is employed, which includes: a nozzle which holds the adhesive; a coating needle which is discharged from the nozzle in a state where the adhesive is adhered to the tip; and a control unit which controls moving speed of the coating needle to separate the adhesive into the tip of the coating needle and the nozzle.

A method for applying a product by roller on a surface of a substrate (112) transported horizontally with respect to an application head (111, 111) is discloses. The method includes moving the application head (111, 111) immediately from a lowered position of the application head (111, 111), wherein the application roller (122, 122) applies the product in a predetermined position of the surface of the substrate, to a raised position of the application head (111, 111), wherein the application roller (122, 122) does not apply product; or vice versa. An application system using the method for applying a product by roller is also disclosed.

A device for treating substrates by a treating liquid has at least one rotatably supported support roller which a substrate to be treated rests on during operation. The support roller has a hollow cylinder having a porous rigid material which the substrate to be treated rests on during operation. The device is configured to deliver, during operation, treating liquid via the interior of the hollow cylinder of the at least one support roller through the porous rigid material to the external surface of the hollow cylinder in order to treat at least one surface of the substrate by the treating liquid. The device is configured to treat several substrates in the form of plate-shaped separate wafers arranged one behind the other and/or next to one another in the device, by the treating liquid and to transport the substrates in a transport plane during the treatment.

A coating device includes a coating member, a nip forming member, a pair of conveying members, and circuitry. The nip forming member forms a coating nip together with the coating member. The pair of conveying members is opposed each other to nip and convey a recording medium to the coating nip. The circuitry is configured to cause the pair of conveying members to release nipping of the recording medium at timing when a leading end of the recording medium reaches the coating nip.

A method for coating a surface of a substrate may involve coating the surface of the substrate with a wet coating by way of a coating station, conveying the substrate by way of a conveying device, and detecting the surface coated with the wet coating by producing a thermal image of a detection region that comprises part of the surface. The thermal image may be recorded in a spectral range that includes a wavelength between 1 micrometer and 20 micrometers. Further, the detection region may be located directly downstream of the coating station, or the detection region may at least partially include the coating station.

An apparatus and method for producing a coated analytic substrate using a compact and portable automated instrument located in the laboratory setting at the point of use which can consistently produce one or a plurality of coated analytic substrates on demand for using the analytic substrate immediately after coating, preferably without a step of rinsing the coated analytic substrate before use. The apparatus preferably uses applicator cartridges having a reservoir containing the coating compositions used to form the coatings. Preferably the cartridges are removable and interchangeable to facilitate the production of individual analytic substrates having different coatings or different coating patterns. These coated analytic substrates have superior specimen adhesion characteristics due to the improved quality of the coatings applied by the coating apparatus and due to the quickness with which the coated analytic substrates can be used in the lab after production.

The subject matter of the present invention is a method for producing coated, and in particular painted, building boards (1), preferably for the interior finishing of buildings. First, the respective building board (1) is provided on its longitudinal edges (2) and/or transverse edges with a bevel (4). Then, the respective building board (1) is transferred to a rubber-like transporting belt (7) in such a way that the edges (2) respectively provided with the bevels (4) are arranged transversely in relation to the conveying direction (F) of the transporting belt (7) and the bevels (4) are arranged adjacent to a visible side (6) of the building board (1), facing away from the transporting belt (7). Finally, a coating material, and in particular paint (13), is applied to the visible side (6) of the building board (1) and respective bevel areas (5) of the bevels (4) in one operation with the aid of at least one roller (11) arranged above the transporting belt (7) and rotating substantially transversely in relation to the conveying direction (F).
