Abstract

Die Erfindung betrifft ein Auftragwerk zum direkten Auftragen eines flüssigen oder pastösen Mediums (12) auf eine laufende Materialbahn (4), umfassend mindestens eine zur Einstellung eines Querprofils mit Stellgliedern (14v) ausgestattete, in eine Vielzahl von sich quer zur Laufrichtung der Materialbahn erstreckende Zonen (Zv) eingeteilte und durch die Stellglieder (14v) zonenweise profilierbare Vordosiereinrichtung (V), wobei jeder Zone (Zv) wenigstens ein Stellglied (14v) zugeordnet ist, sowie mindestens eine der Vordosiereinrichtung (V) in Laufrichtung der Materialbahn nachgeschaltete, ebenfalls mit Stellgliedern (14e) ausgestattete, in eine Vielzahl von sich quer zur Laufrichtung der Materialbahn erstreckende Zonen (Ze) eingeteilte und durch die Stellglieder (14e) zur Einstellung eines Querprofils zonenweise profilierbare Enddosiereinrichtung (E), wobei jeder Zone (Ze) wenigstens ein Stellglied (14e) zugeordnet ist. Die Zonenbreiten (bv, be) der Vordosiereinrichtung (V) und der Enddosiereinrichtung (E) sind gemäß einer ersten Erfindung identisch.
Gemäß einer zweiten Erfindung sind die Zonenbreiten (bv, be) voneinander verschieden.

The invention relates to an application unit for the direct application of a liquid or pasty medium (12) to a running material web (4), comprising at least one element equipped with actuators (14 v ) for setting a transverse profile, which extends in a plurality of directions transverse to the running direction of the material web Zones (Z v ) divided and by means of the actuators (14 v ) profilable pre-metering device (V), each zone (Z v ) being assigned at least one actuator (14 v ) and at least one of the pre-metering device (V) in the direction of travel of the material web Downstream, also equipped with actuators (14 e ), divided into a plurality of zones (Z e ) extending transversely to the direction of travel of the material web and which can be profiled zone by zone by the actuators (14 e ) for setting a cross profile, each zone (Z e ) at least one actuator (14 e ) is assigned. The zone widths (b v , b e ) of the pre-metering device (V) and the final metering device (E) are identical according to a first invention.
According to a second invention, the zone widths (bv, be) are different from one another.
