Abstract

Die Erfindung betrifft ein Auftragwerk zum direkten oder indirekten Auftragen eines flüssigen oder pastösen Mediums auf eine laufende Materialbahn, umfassend einen Tragbalken, eine dem Tragbalken (2) gegenüberliegende Gegenwalze (4), eine sich über die Breite der Gegenwalze (4) erstreckendes Rakelelement (6), das über eine Halteeinrichtung (8) an dem Tragbalken (2) lösbar fixiert ist, wobei die Halteeinrichtung (8) ein Stellglied (12) und einen durch das Stellglied (12) betätigbaren hebelartigen und mit dem Rakelelement (6) kontaktierbaren (K) Anpreßmechanismus (10) zum Anpressen des Rakelelements (6) an ein Gegenlager (8.2) aufweist und der hebelartige Anpreßmechanismus in einem Bereich zwischen der Gegenwalze und dem Tragbalken liegt, sowie wenigstens ein auf den hebelartigen Anpreßmechanismus (10) direkt oder indirekt einwirkendes elastisches Federelement (14), gegen dessen Rückstellkraft das Stellglied bei seiner Aktivierung wirkt und das den Anpreßmechanismus bei Deaktivierung des Stellgliedes durch seine Rückstellkraft von dem Kontakt (K) mit de Rakelelement (6) löst und dieses freigibt.

The invention relates to an application unit for the direct or indirect application of a liquid or pasty medium to a running material web, comprising a support beam, a counter roller (4) opposite the support beam (2), and a doctor element (6) extending over the width of the counter roller (4) ), which is detachably fixed to the supporting beam (2) by means of a holding device (8), the holding device (8) comprising an actuator (12) and a lever-like lever (K ) Has pressing mechanism (10) for pressing the doctor element (6) against a counter bearing (8.2) and the lever-like pressing mechanism lies in a region between the counter roller and the supporting beam, and at least one elastic spring element acting directly or indirectly on the lever-like pressing mechanism (10) (14), against the restoring force of which the actuator acts when it is activated and which the contact pressure mechanism when deactivated ivierung of the actuator by its restoring force from the contact (K) with the doctor element (6) and releases it.
