Abstract: In the paper coating operation a wet or dry edge from coating composition is formed on the, seen in the direction of movement of the paper web, downstream side of the doctor, the so-called stalagmite formation. This stalagmite formation leads to various problems in the papermaking process and especially occurs at high speeds of the paper web and/or a high solids content of the coating composition, which two operating conditions are exactly required to obtain a maximum paper yield and a high paper quality. According to the invention the stalagmite formation is effectively prevented by supplying a fluid inhibiting the stalagmite formation to an area bounded, on the one hand, by the paper web and, on the other hand, by the above side of the doctor blade.

Abstract: A method and apparatus for producing paperboard, the method comprising the steps of applying a coating mix layer having a thickness greater than that of the final coat thickness to the surface of the web being coated using a coating mix formulation in which the solids content is at least 55%, passing the web with the coat applied thereto to a doctor blade located downstream in the travel direction of the web at a distance from the applicator apparatus such that the dwell time from the application step of the coating mix to the doctoring step is at least 130 ms, and smoothing the coat layer to its final thickness by means of a doctor blade. By this method a smooth surface can be obtained even on high coat weights.

Abstract: In an applicator a thick coating of a liquid is applied to a flexible web that is then moved through a doctor assembly where excess liquid is scraped from the web. The doctor assembly has a generally stationary support at the station and a holder beam extending longitudinally substantially parallel to the web and transverse to a web travel direction. The beam is movable on the support transversely of itself and of the travel direction forward toward and backward away from the web and has a front face directed toward the web and an opposite back face turned away from the web. The support has front and back faces generally parallel to and respectively confronting the front and back faces of the holder beam. A doctor rod held in the holder beam is juxtaposable thereby with the web to scrape the excess liquid from the web. Front inflatable hoses are provided between the front faces of the holder beam and support and back inflatable hoses between the back faces of the holder beam and support. These hoses can be selectively inflated and deflated so that when the front hose is inflated at greater pressure than the back hose the holder beam moves backward in the support and when the back hose is inflated at greater pressure than the front hose the holder beam moves forward in the support.

Abstract: An arrangement for dosing with a blade, in coating machines or similar, onto a running web of paper or cardboard carried by a roll in or with the arrangement. The blade is forced by means of a hold-down or several hold-down sections on the roll respectively the web. A transmitter transmits light, notably laser light. The blade features in the area between the contact line of the hold-down on it, and its contact line on the roll respectively the web, on its side away from the roll, at least one light-reflecting layer for reflection of the light ray directed by the transmitter at the layer. A receiver registers the position or angle of the ray reflected upon it by the light-reflecting layer of the blade. A controller is provided for controlling, dependent on the position signal of the receiver for the reflected light ray, the angular position of the blade, notably in its area between the contact line of the hold-down or the hold-down section and the roll.
