Abstract: A coating device, comprising a supply roller having a first contact surface, and a counter-roller placed opposite the supply roller and a second contact surface substantially parallel to the first contact surface. The contact surfaces are at least a substrate width in width and maintain a mutual gap for receiving the substrate therein in contact with both contact surfaces. The supply roller and counter-roller are each rotatable about their central axis. A liquid is supplied to the supply roller. At least the contact surface of the supply roller or the counter-roller is axially adjustable along the central axis thereof. Adjusting means align an edge of the contact surface of the supply roller and the counter-roller with a side of the substrate. An opposite edge of the other of the supply roller and the counter-roller is aligned with an opposite side of the substrate.

Abstract: 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.

Abstract: A system for analyzing web breaks in a printing press is provided. The system includes sensing devices for monitoring the web, the printing press and detecting a web break. The system includes a database with predetermined web break causes, a real cause probability calculation algorithm for calculating the probability that the corresponding predetermined web break cause is the real cause of a detected web break as a function of the outputs of the sensing devices and a real web break cause determining processor for executing each real cause probability calculation algorithm. The predetermined web break causes are ranked according to the calculated real cause probabilities, and the web break cause among the predetermined web break causes with the highest real cause probability as the cause for the detected web break is identified. A web printing press and method are also provided.

Abstract: A coating device for moistening a flat substrate, particularly a paper web, comprising a liquid bath which is in contact with the liquid to be applied and a coating roller which is in contact with the liquid in order to take up a quantity thereof and transfer it to the substrate. The coating roller comprises a cylinder body having at a periphery thereof a cylinder surface which is covered with an absorption layer which is able and configured to take up liquid from the liquid bath and supply it to the substrate.
