    Abstract: A method and apparatus for applying a film of liquid pigmented coating material to a moving web of paper at, and between, a low limit of two pounds per ream per side and a high limit of fifteen pounds per ream per side. The method and apparatus utilize a reservoir of liquid coating material established between a forward liquid coating material seal and a rearward pneumatically loaded and clamped doctor blade spaced a small distance of a few inches or less from the liquid seal. The reservoir is pressurized in the range of 7 to 150 inches of water so that the coating material is applied under pressure to the moving web and then almost instantaneously wiped by the doctor blade. The reservoir is formed by two relatively movable, sealed members which may be opened for easy cleaning, and may have one or more internal coating material distribution headers at its end opposite the web to uniformly distribute the coating material. A reliable, duplicable adjustment for a movable element forming the front edge of the reservoir is provided to establish and control the liquid seal. End dams are located at the ends of the reservoir between the doctor blade and cut-away portions of the movable element to control undesired outflow of coating material. Further, a pair of such applicators may be arranged on opposite sides of the web to simultaneously coat both sides of the web. In addition, the method and apparatus have other features providing easy adjustment, operating, clean-up, high, low or medium weight coatings better than any single prior device and method, and better lightweight coatings than prior devices and methods.

    Abstract translation: 一种用于将液体着色涂层材料膜施加到移动的纸幅的方法和装置，并且在每侧每磅2磅的下限和每侧15磅的高限之间。 该方法和装置利用液体涂覆材料储存器，其建立在前液体涂覆材料密封件和与液体密封件间隔几英寸或更小的小距离的后向气动加载和夹紧的刮刀之间。 储存器在7至150英寸水的范围内被加压，使得涂层材料在压力下施加到移动幅材上，然后几乎被刮刀瞬间擦拭。 储存器由两个相对可移动的密封构件形成，其可以打开以便于清洁，并且在其与纸幅相对的端部处可以具有一个或多个内部涂料分配集管，以均匀地分布涂料。 提供了形成储存器前边缘的可移动元件的可靠的可重复调节，以建立和控制液体密封。 末端坝位于储存器的可移动元件的刮刀和切割部分之间的端部，以控制涂层材料的不期望的流出。 此外，一对这样的施加器可以布置在幅材的相对侧上以同时地覆盖幅材的两侧。 此外，该方法和装置具有比现有装置和方法更好的任何单一现有装置和方法以及更好的轻质涂层，提供易于调节，操作，清理，高，低或中等重量的涂层的其它特征。

    Abstract: The invention concerns a painting edge limiter for a painting arrangement with a short residence time for coating continuous material (2), in particular paper. This edge limiter seals laterally at both ends a coating slip chamber which is formed between the barrier wall (4) and doctor blade element (3). The application zone (2) which builds up on the paper web is thus covered flat at each edge by the formatting plate (8) of the painting edge limiter. The formatting plate holder (7) is rigidly connected to the sealing block (5) and projects outwards over the barrier wall (4). On the side remote from the formatting plate (8), the sealing block (5) has at least one depression (11) which is connected to a water supply (20) by a channel (13). A narrow sealing gap (15), 1 to 3 mm wide, is formed between the formatting plate (8) and the sealing block (5). The water introduced through the depression (11) into the sealing gap (15) generates a pressure pad and urges the formatting sheet (8) flat against the paper web.

    Abstract: A chamber doctor blade assembly includes axially spaced lateral cheeks that seal the ends of the ink reservoir. Each of these lateral cheeks has a sealing face that conforms to the curvature of the screen roller with which the chamber doctor blade is used. These sealing faces are provided with lubricant reservoirs. The lateral faces also have leading edges bent or flared out to form strippers which remove excess beads of ink from the screen roller.

    Abstract: An edge dam assembly for an applicator for applying a film of coating material on a moving web of paper carried through an application zone, is characterized by a seal element at each side end of the zone. To prevent leakage of coating liquid past the seal element, air is introduced through the element and into the side end of the zone adjacent to the element. The air forms an air barrier pocket at the side end of the zone, which is void of coating liquid, whereby coating liquid is maintained in the zone inwardly of the seal elements.
