A coating device for supplying a liquid to a substrate, particularly in the form of an optionally printed web, foil, strip or sheet, comprises a reservoir for holding a quantity of liquid. Coating means are provided which are able and configured to take liquid from the reservoir and transfer it to the substrate. Supply means deliver the liquid into the reservoir during operation. The supply means are controllable and are able to lead a constant liquid flow into the reservoir. The reservoir is provided with level detecting means which are able and configured to detect a liquid level in the reservoir. Provided between the level detecting means and the coating means is a control which controls the coating means during operation on the basis of a detection (LS) of the liquid level in the reservoir in order to maintain the liquid level at a fixed value.

A device for a lacquer transfer includes a frame, transfer roller with a circumferential lateral wall, drive unit for rotating the transfer roller, and slit nozzle with a muzzle end for dispensing lacquer. The slit nozzle includes a first nozzle-part, second nozzle-part and deformation unit. The deformation unit is attached to the first nozzle-part, the lateral wall passing in a rotation direction subsequently the deformation unit and the muzzle end during transfer unit rotation. The lateral wall of the transfer roller is deformed by the deformation unit in the radial direction resulting in a deformation section of the lateral wall in the rotation direction behind the deformation unit, the muzzle end of the slit nozzle arranged for dispensing lacquer into depressions of the lateral wall. The transfer roller can roll with the outside contact surface on a work surface of a work piece for transferring lacquer from the depressions to the work surface of the work piece.

A method of preparing a blank for forming a carton includes obtaining a blank, positioning the blank in a blank feeder assembly of a system for preparing blanks, moving the blank from the blank feeder assembly to a conveyor assembly of the system, and activating the conveyor assembly to move the blank along a coating applicator assembly of the system, the coating applicator assembly having a container defining a reservoir holding a volume of a coating and an applicator wheel rotatably supported at least partially in the reservoir of the coating applicator assembly. The method further includes applying a portion of the coating from the reservoir to a portion of the blank.

A method for applying a multi-layer coating includes passing a substrate through a nip defined by two rolls to apply a first thickness of a first liquid coating material, applying a second liquid coating material on the first liquid coating material having the first thickness as applied by passing through the nip, and controlling a thickness of the applied second liquid coating material.

The invention relates to a device for producing a web of corrugated cardboard comprising a first corrugating roller for producing a corrugated web. The device further has a glue application roller for applying glue to the corrugated web. The glue application roller is associated to the first corrugating roller so as to form a gap and is displaceable relative to the first corrugating roller in order to influence the glue application quantity. The device further comprises a displacement device for displacing the glue application roller relative to the first corrugating roller and a pressing device for pressing a laminating web against the corrugated web. It is further provided with a regulating device which is in signal connection with the displacement device, a gap regulating unit in order to adjust a gap width of the gap between the first corrugating roller and the glue application roller, and a contact force regulating unit in order to adjust a contact force applied to the first corrugating roller by the glue application roller.
