摘要： Air entrained within the pond of a coating applicator is influenced toward a designated region for removal. The region is formed by a recessed air collector which sets up a high-recirculation, low-pressure zone within the pond. Entrained air bubbles migrate to the collector. The collected air and excess coating is drawn out of the collector cavity by a plurality of perforations which discharge to a collection cavity at a lower pressure or partial vacuum. The collector structure may be employed in various coater/size press configurations.

摘要： A Y-shaped flow splitter (36) passes papermaking fluid with some fibers with reduced clogging and has a flat surface (68) opposite the leg (44) of the Y where the flow divides into the two arms (46) of the Y. A generally flat rectangular surface is positioned opposite the leg of the Y of the flow splitter which divides the flow evenly without providing a place for fibers to collect and thus clog the flow through the splitter. The splitter allows the flow to a pair of dilution tubes to be controlled by a single valve with a single flow passage reducing clogging and valve cost. The flow splitter is constructed of stainless steel by a casting process. A process known commercially as the Extrudehone process is used to produce smooth flow passages.
摘要翻译： Y型分流器（36）将造纸流体与一些具有减少堵塞的纤维通过，并且具有与Y的腿部（44）相对的平坦表面（68），其中流动分为Y的两个臂（46）。大致平坦的矩形表面与分流器的Y的腿相对定位，其均匀地分隔流动，而不为纤维提供收集的位置，从而堵塞通过分流器的流动。分流器允许流到一对稀释管，由单个阀控制，单个流道减少堵塞和阀门成本。流量分配器通过铸造工艺由不锈钢构成。用Extrudehone工艺商业化的方法用于生产平滑的流动通道。

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.
摘要翻译：施用头位于背衬辊下方，可以在其上拉出基底。涂抹器头具有壳体，该壳体在上部机器溢出唇缘和下降机提取板或预测板之间包含涂料池。相对较低速度的涂层材料流入邻近溢流唇缘的池塘中。预测量板从涂层入口径向延伸到靠近并与背衬辊会聚的位置，在该位置预测涂层施加到基底上的涂层量。预测板优选具有多个孔，涂层和空气通过该孔被拉出。计量元件在预测量板的下游间隔开，并且在它们之间构造低压区域。空气和涂层通过阀从低压区抽出，从而控制压力。

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 uniform film of coating is delivered onto a substrate such as paper, felts and blankets by a film applicator (20; 100; 120; 142) which has a static converging wedge (32; 88; 108; 128; 150), an adjustable converging wedge (33), and an extraction channel (45; 92, 112; 132; 154) located between the two wedges. As a unit, the film applicator minimizes the hydrodynamic flow instabilities, as well as reduces flow variations associated with a nonuniform feed and a dynamic contact line. The film applicator also removes entrained air and excess coating from the application zone in order to improve the flow stability and machine runnability.
摘要翻译：通过具有静态会聚楔（32; 88; 108; 128; 150）的膜施加器（20; 100; 120; 142）将均匀的涂层膜输送到诸如纸，毛毡和毯子的基底上，可调节会聚楔（33）和位于两个楔之间的提取通道（45; 92,112; 132; 154）。作为一个单元，膜施加器使流体动力学流动不稳定性最小化，并且减少与不均匀进料和动态接触线相关联的流动变化。薄膜施加器还从施加区域除去夹带的空气和过量的涂层，以改善流动稳定性和机器运行性能。

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.
