Abstract: 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.

Abstract translation: 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。
