Provided is a coating apparatus including: a liquid coating section; an adjusting section which is configured to be capable of coming into contact with and/or separating from the liquid coating section, and which adjusts an amount of the liquid in the liquid coating section; and a hardware processor differentiating the contact timing between the coated medium and the liquid coating section and the contact timing between the liquid coating section and the adjusting section in a case where the coated medium is coated with the liquid.

A device for a lacquer transfer is disclosed having a transfer roller, the transfer roller includes a cylindrical support body, a first ring element, a second ring element, and a tire, wherein the tire comprises a middle section forming a circumferential outer contact surface with several depressions. The transfer roller is configured to roll with the outer contact surface on a work surface of a workpiece for transferring lacquer from the outer contact surface and from the depressions to the work surface of the workpiece. The tire includes two annular end sections, which are attached to the support body resulting in two axially separated and circumferentially extending connections. The tire, the connections, and the outer shell of the support body are fluid-tight and arranged such that a fluid-tight main cavity is formed between the tire and the support body. The first and second ring elements are arranged in the main cavity and seated on the support body at a predefined distance in an axial direction (A) of the transfer roller from one another.

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.

An alignment film coating method is provided, and includes steps of: supplying alignment film solution to a coating roller at a first end of a machine table; placing a first substrate on the machine table; moving the coating roller from the first end to a second end of the machine table; supplying alignment film solution to the coating roller at the second end of the machine table; taking the first substrate down from the machine table, and placing a second substrate on the machine table; and, linearly moving the coating roller from the second end to the first end of the machine table.

Various embodiments of the present disclosure provide lumber stack marking machines and methods of applying marking sets to lumber stacks.

Controlling application of adhesive on a substrate includes using a gas sensor, obtaining a first sensor signal. The first sensor signal indicates a partial pressure of a gas that arises from a constituent of the adhesive. Based at least in part on this partial pressure, the controller either controls an applicator's delivery of the adhesive to a substrate or causes an error signal indicative of the adhesive's unsuitability for adhesion.

A vacuum processing system for a flexible substrate is provided. The vacuum processing system includes a first chamber adapted for housing a supply roll for providing the flexible substrate; a second chamber adapted for housing a take-up roll for storing the flexible substrate after processing; a substrate transport arrangement including one or more guide rollers for guiding the flexible substrate from the first chamber to the second chamber; a maintenance zone between the first chamber and the second chamber wherein the maintenance zone allows for maintenance access to or of at least one of the first chamber and the second chamber; and a first process chamber for processing the flexible substrate.
