    • Coating apparatus of the trailing blade type which includes means for providing a coating to a surface of a continuous web, in which the coating consists of one or more stripes thereof. Each stripe may be relatively wide or relatively narrow. The coating material may be of the hot melt type, in which the coating material is solid at normal room temperature and is a liquid only at temperatures considerably above room temperature. The coating material may be of the solvent type or of the water emulsion type, or which is a liquid at normal room temperatures and in which a drying process removes a vehicle from the material and a solid coating remains. A thin flexible shield which engages selected portions of the web is disposed between the trailing blade and the web to prevent coating of the web in the portion thereof which is engaged by the shield.
    • 后叶片式涂覆装置包括用于向连续纤维网的表面提供涂层的装置,其中涂层由其一条或多条形成。 每个条纹可以相对宽或相对窄。 涂层材料可以是热熔型,其中涂层材料在正常室温下是固体,并且仅在远远高于室温的温度下是液体。 涂料可以是溶剂型或水乳液型,或在正常室温下为液体,其中干燥过程从载体中除去载体并保留固体涂料。 与纤维网的选定部分接合的薄柔性护罩设置在牵引叶片和腹板之间,以防止幅材在其与屏蔽件接合的部分中的涂覆。

    • The invention refers to a method and a device for varying the application amount of a coating agent at the blade coating of a moving material web (24,40,51), preferably a paper web, by corresponding control of the engagement pressure of the coating blade (20,43,50,68) against the web (24,40,51) which exhibits a coating agent surplus. The web is supported by a support, preferably a rotating support roller (25,41), and the blade is along one of its longitudinal sides clamped in a blade holder (21,44,49,69), moreover the blade is initially, with a certain force and thereby in an obtained arcuate shape, brought, with the opposite longitudinal side thereof, into engagement with the web, in a certain given angle between blade tip and web, and with a thereby defined engagement area.A control pressure is exerted onto the major side of the blade when the engagement pressure is to be changed, the attack point of the control pressure on the blade is displaced in the transverse direction of the blade, towards or away from the web. At the same time the size of the control pressure is adjusted. Said displacement and adjustment are done partly to provide the desired blade engagement pressure and partly to mainly maintain the angle between the blade tip and the web.
    • 本发明涉及一种用于通过相应地控制涂层的接合压力来改变移动材料纤维网(24,40,51),优选纸幅的刮刀涂层处的涂料的施用量的方法和装置 叶片(20,43,50,68)抵靠表现出涂层剂剩余的幅材(24,40,51)。 腹板由支撑件支撑,优选地为旋转的支撑辊(25,41)支撑,并且叶片沿其一个纵向侧面夹紧在刀片保持器(21,44,49,69)中,此外, 以一定的力,从而获得的弓形形状,使其相对的纵向侧与叶片在叶片尖端和腹板之间以特定的角度与织物接合,并具有由此限定的接合面积。 当要改变接合压力时,控制压力施加到叶片的主侧上,叶片上的控制压力的攻击点在叶片的横向方向上朝向或远离幅材位移。 同时调整控制压力的大小。 所述位移和调节部分地被提供以提供期望的叶片接合压力,并且部分地主要保持叶片尖端和幅材之间的角度。

    • An edge dam for an applicator for applying a film of coating liquid to a moving web of paper carried through an application zone, is characterized by a seal element at each side end of the zone for substantially sealing the side end of the zone, thereby to impede a flow of coating material out of the zone. At least one orifice is formed through the seal element outwardly of the zone, and the orifice is connected with a supply of water under pressure for directing a flow of water against the peripheral edge of the web moving therepast, thereby to wet the edge and flush the same of any coating material seeping past the element. In consequence, edge stickers and coating liquid pickup on the web edge are substantially eliminated.
    • 用于将涂布液膜施加到通过施加区域运送的纸张的施加器的边缘坝的特征在于用于基本上密封区域的侧端的区域的每个侧端处的密封元件,从而 妨碍涂层材料流出该区域。 至少一个孔通过该区域外的密封元件形成,并且孔口与压力下的水源连接,以将水流引导到幅材移动的周边边缘,从而润湿边缘并冲洗 任何涂层材料渗透过元件都是相同的。 因此,幅面边缘上的边缘贴纸和涂布液体拾取器基本上被消除。
