    Abstract: In a device for the coating of a running web of paper or cardboard, provisions are that in a press gap formed between two rolls a coating substance applied in a very small quantity on the surface of the one roll is first pressed on the web leaving a very thin coat on the web which, however, covers all spots including the "mounds" of microroughness. Next, the second coat can be applied and dosed on the still moist first coat with the usual means. In the process, the first coat is preferably dosed on the shell of the first roll, by means of the peripheral grooves of a rotary doctor. The same may be performed also as regards the second coating on the web.

    Abstract: Apparatus for maintaining a relatively placid pool of liquid coating material in the trough between two nipped rolls comprises a pair of deckles, one disposed near either end of the nipped rolls, each of the deckles having an edge generally conforming to a segment of the adjacent roll to effectively form an end of the trough formed by the rolls. At least one of the deckles has one or more openings which permit the liquid coating material to flow laterally out of the trough and through the deckle at a rate proportional to the depth of the coating material in the trough. Controlling the lateral outward flow of material from the trough stabilizes both the turbulence of the liquid coating material in the trough and the surface condition of the coating material.

    Abstract: The invention concerns a device and method for limiting of the width of coating in coating of paper or board. The coating agent is spread onto a moving base to be coated by means of a coating device provided with a grooved coating bar. The coating agent is spread substantially only over the width of the web and any coating agent extending substantially beyond the web width is scraped off the base to be coated with the aid of smooth end areas fitted at both ends of the coating bar. The invention is also related to a device for carrying out the method.

    Abstract: The coating device features a first applicator which, to begin with, forces coating substance applied on the shell of a web roll (1), in a press gap formed between said roll and a press roll (2), into the web (W), thereby impregnating it. This makes it possible to apply with maximum uniformity and without web breaks and wrinkles, immediately successively, a second coating layer during the still wet condition of the first layer where, naturally, again a web guide roll (3) is provided.

    Abstract: A coating press apparatus is disclosed for coating a first and second side of a pressed web formed in a forming section of a papermaking machine. The apparatus includes a first press roll which defines a smooth imperforate first surface. The first surface cooperates with the first side of the web. A first backing roll cooperates with the first press roll for defining therebetween a first nip for the passage therethrough of the web. A first felt supports the web during passage through the first nip and a first short-dwell coater applies a coating directly to the surface of the first press roll upstream relative to the first nip such that a smooth and even first layer of the coating substance is applied to the first side of the web during passage of the web through the first nip. A second short-well coater is disposed downstream relative to the first nip for applying a smooth and even second layer of coating substance to the second side of the web such that the first and second sides of the resultant pressed web exhibit a higher coating content than the coating content betwen the first and the second sides thereby enhancing the surface properties and resulting printability of the web.
