摘要： An improved short dwell type coater (18) and method are provided. The coater (18) can coat a web (26) directly or a moving roll surface (26' or 27') as in a film coater or size press. The flow path in the coater includes a flow modifier (54) shaped to have the introduced coating first turn upstream relative to the web (26) or roll surface (26' or 27'), then turn across a curved surface (73, 74) toward the web (26) or roll (26' or 27') and around the flow modifier (54). The flow then converges toward the top of the flow modifier (54) and passes the tip (63) of the flow modifier. Some flow remains on the web (26) or roll (26' or 27') and is subsequently doctored, while most is turned away from the web (26) or roll (26' or 27') and merged with the incoming flow. A gap (46) filled with coating overflow provides a liquid seal. This coater and method use coating, reduce vortices and streaking, and can operate at higher speeds.
摘要翻译：提供改进的短停留式涂布机（18）和方法。涂布机（18）可以如薄膜涂布机或压片机那样直接涂布卷筒纸（26）或移动的辊表面（26'或27'）。涂布机中的流路包括流动改性剂（54），其形状为使引入的涂层首先相对于网（26）或辊表面（26'或27'）向上游转动，然后转过弯曲表面（73,74 ）朝向腹板（26）或辊（26'或27'）并且围绕流动调节器（54）。然后，流体朝向流动改性剂（54）的顶部会聚，并使流动调节剂的末端（63）通过。一些流动保留在幅材（26）或辊（26'或27'）上，随后被修整，而大多数流动从纸幅（26）或辊（26'或27'）转动并与进入的流合并。填充有涂层溢流的间隙（46）提供液体密封。这种涂布机和方法使用涂层，减少涡流和条纹，并可以以更高的速度运行。

摘要： A coater head (22) is positioned beneath a backing roll (24) and has a housing divided into three sections (25, 27, 41). A first coating pond (28) is defined between an overflow barrier and a first wall (33). A converging plate (32) extends between the first wall (33) and a second wall (35), and converges toward the web, and a second pond (43) is defined between the plate and an end wall (39). Coating is introduced to both ponds. A low pressure cavity (37) is defined beneath the converging plate (32) and between the first wall (33) and the second wall (35). The cavity (37) opens (72) to the second pond (43), and draws air and excess coating from the second pond (43). The web is prewetted as it passes through the first pond (28), and coating deprived of entrained air is applied to the web in the second pond (43). Coat weight uniformity and increased machine speeds are thus achievable.
摘要翻译：涂布机头（22）位于支承辊（24）的下方，并具有分成三个部分（25,27,41）的壳体。第一涂覆池（28）被限定在溢流挡板和第一壁（33）之间。会聚板（32）在第一壁（33）和第二壁（35）之间延伸并且朝向幅材会聚，并且在板和端壁（39）之间限定第二池（43）。将涂层引入两池。低压腔（37）被限定在会聚板（32）下面和第一壁（33）和第二壁（35）之间。空腔（37）向第二池塘（43）打开（72），并从第二池塘（43）抽出空气和多余的涂层。当纸幅通过第一池塘（28）时，预先润湿，并且将剥离的夹带空气的涂层施加到第二池塘（43）中的幅材上。因此可以实现涂层重量均匀性和增加的机器速度。

摘要： A device (10) for sealing one or both ends of a metering nip. The device (10) comprises a high pressure chamber (12) and a low pressure chamber (14), with each chamber (12,14) comprising a sealing element (18,22) operatively adapted so as to form a seal with the metering nip. The low pressure chamber (14) is in contact with the fluid material metered by the metering nip. The high pressure chamber (12) is pressurized with a gas that will prevent substantially all of the fluid material from leaking out past the sealing element (18) of the high pressure chamber (12), and the low pressure chamber (14) is pressurized to a pressure that will not force a substantial amount of the pressurized gas into the fluid material to be metered.

The coater head includes at least two chambers and an extended outflow bubble to increase the zone of contact between coating liquid and the traveling web. Improved, coating quality also results from controlled flow characteristics through the coater head having a feed zone length-to-depth ratio of four or more.

摘要： An applicator head is positioned beneath a backing roll over which a substrate can be drawn. The applicator head has a housing which contains a pond of coating material between an up machine overflow lip and a down machine extraction plate or premetering plate. Coating material at a relatively low velocity flows into the pond adjacent to the overflow lip. The premetering plate extends radially from the coating inlet to a position proximate to and converging with the backing roll, where it premeters the amount of coating applied to the substrate. The premetering plate preferably has a plurality of holes through which coating and air are drawn. A metering element is spaced downstream of the premetering plate, and a low pressure area is constructed therebetween. Air and coating are drawn from the low pressure area through a valve, and the pressure thereby controlled.

摘要： A method of and apparatus for applying coating liquid to a web of paper traveling over a web supporting surface at speeds of 3,000, 4,000 and more feet per minute to produce a coated web free of streaking and other imperfections comprises apparatus for and the sequential steps of distributing coating liquid in a turbulent state over the supported web through a limited application zone within a very short dwell time of the turbulent liquid on the web; subjecting the coating liquid on the supported web to an initial doctoring by means of a primary doctor blade biased under pressure against the coated web at the rear edge of the application zone to form on the web downstream from the zone a relatively quiescent layer of coating liquid having a wet film thickness sufficiently in excess of the final wet film thickness to accommodate a subsequent final wet film doctoring of the coating liquid on the web; and, at a location downstream and isolated from the application zone, subjecting the relatively quiescent layer of excess coating liquid on the supported web to a final doctoring by means of a final doctor blade biased under pressure against the coated web to remove the excess coating from the web and to level and smooth the coating retained on the web to final wet film thickness and smoothness. The method and apparatus of the present invention produces essentially a constant paper smoothness in relation to web speed at which it was coated and subsequently supercalandered, i.e., smoothness does not decrease at higher web speeds, and produces higher gloss with less decline in gloss at higher web speeds.
摘要翻译：一种用于将涂布液施加到以每分钟3,000,4,000和更多英尺的速度在纸幅支撑表面上行进的纸幅的产品的方法和装置，以产生没有条纹和其它缺陷的涂布纸，包括以下步骤：在湍流状态下，在幅材上的湍流液体的非常短的停留时间内，通过有限的施加区域将湍流状态的涂布液分配到所述被支撑的幅材上; 通过在施加区域的后边缘处的压力下被压在涂覆的幅材上的初级刮刀将受载幅材上的涂布液进行初始刮涂，以在该区域的下游形成相对静止的涂布液层具有足够超过最终湿膜厚度的湿膜厚度以适应随后的最终湿膜上的涂布液在纸幅上的刮涂; 并且在下游并与施用区隔离的位置处，通过在压力下偏压涂覆的幅材的最终刮刀将经过支撑的幅材上的过量涂布液的相对静止层进行最终刮除，以从并且使保持在幅材上的涂层的平整和平滑化到最终的湿膜厚度和平滑度。本发明的方法和设备基本上产生了相对于其被涂布并随后被超量化的幅材速度的恒定的纸张光滑度，即，在较高幅材速度下平滑度不降低，并产生更高的光泽度，较高的光泽度下降较少网速。
