Abstract

Die vorliegende Erfindung betrifft ein Dichtungselement zur stirnseitigen Abdichtung einer Rakelkammer, gegenüber einer rotierenden Rasterwalze, mit einem Dichtungskörper (1) der an seiner Oberseite eine Dichtungsfläche (2) aufweist. In dem Dichtungskörper (1) ist ein in der Längsrichtung verlaufender und zur Verdichtungsfläche hin offener, insbesondere gradliniger Kanal (3) ausgebildet, welcher die Dichtungsfläche zumindest im Bereich des zentralen Dichtungsflächenabschnitts segmentiert, wobei in dem Dichtungskörper (1) zwei in der Längsrichtung verlaufende und zur Dichtungsfläche offene, insbesondere geradlinige Kanäle (3) ausgebildet sind, welche die Dichtungsfläche (2) zumindest im Bereich des zentralen Dichtungsflächenabschnitts (2a) unter Bildung eines zwischen den Kanälen (4) gelegenen mittleren Dichtungsstegs (4) und zwei äußeren Dichtungsstegen (5, 6) segmentieren, wobei der mittlere Dichtungssteg (4) in der Querrichtung des Dichtungskörpers (1) betrachtet mittig entlang der Längsrichtung verläuft.The present invention relates to a sealing element for the frontal sealing of a doctor chamber against a rotating anilox roller, with a sealing body (1) which has a sealing surface (2) on its upper side. A channel (3), in particular a straight line, which runs in the longitudinal direction and is open towards the compression surface and which segments the sealing surface at least in the region of the central sealing surface section, is formed in the sealing body (1). open to the sealing surface, in particular straight channels (3) are formed, which the sealing surface (2) at least in the area of the central sealing surface section (2a) to form a central sealing web (4) located between the channels (4) and two outer sealing webs (5, 6) segment, with the middle sealing web (4) running centrally along the longitudinal direction when viewed in the transverse direction of the sealing body (1).
