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.
