Description

Die vorliegende Erfindung betrifft ein Auftragwerk zum Auftragen eines Fluids auf eine Materialbahn gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to an applicator for applying a fluid to a material web according to the preamble of claim 1.

Auftragwerke der eingangs genannten Art werden insbesondere zum Auftrag eines Gleitmittels auf metallische Folienbahnen verwendet, die nachfolgend ihrer Herstellung abgelängt oder zugeschnitten werden und als Zuschnitte in einem nachfolgenden Tiefziehverfahren in einer Tiefziehvorrichtung zu Formteilen umgeformt werden. In der Tiefziehvorrichtung werden die Zuschnitte von einem Tiefziehstempel in ein Tiefziehgesenk oder eine Tiefziehform eingepresst, wobei der in der Regel beidseitig auf den Zuschnitt aufgetragene Gleitmittelfilm eine Reduzierung der zwischen dem Tiefziehstempel und dem Zuschnitt sowie dem Zuschnitt und dem Tiefziehgesenk während der Umformung auftretenden Reibungskräfte sorgt. Um während des Tiefziehvorgangs eine möglichst einheitliche Beanspruchung der Oberfläche des Zuschnitts mit Reibungskräften und damit bei dem fertiggestellten Umformprodukt eine möglichst gute Oberflächenqualität zu erreichen sowie zur weitestgehenden Reduzierung der zur Durchführung des Umformvorgangs notwendigen Kräfte, die insbesondere maßgeblich sind für die Dimensionierung der Krafterzeuger und damit maßgeblich die Kosten für die Durchführung des Umformverfahrens beeinflussen, erweist es sich als wesentlich, eine möglichst gleichmäßige und flächendeckende Verteilung des Gleitmittels auf der Oberfläche des Zuschnitts zu erreichen.Applicators of the type mentioned are used in particular for the application of a lubricant to metallic film webs, which are cut to length according to their manufacture or cut and formed as blanks in a subsequent deep-drawing process in a thermoforming device to form parts. In the deep-drawing device, the blanks are pressed by a deep-drawing die into a deep-drawing die or a deep-drawing mold, wherein the lubricant film usually applied to the blank on both sides reduces the frictional forces occurring between the deep-drawing die and the blank as well as the blank and the deep-drawing die during the forming process. In order to achieve the best possible surface quality during the deep-drawing process as uniform as possible stress of the surface of the blank with frictional forces and thus in the finished formed product as well as to the extent necessary to reduce the necessary for the implementation of the forming process Forces that are particularly relevant for the dimensioning of the force generator and thus significantly affect the cost of performing the forming process, it proves essential to achieve the most uniform and area-wide distribution of the lubricant on the surface of the blank.

Aus der DE 21 01 294 A ist ein Auftragwerk zum Auftrag eines Fluids auf eine Materialbahn bekannt, das zwei gegensinnig und in Bahnlaufrichtung angetriebene Auftragwalzen aufweist, zwischen denen eine Materialbahn geführt ist. Das Auftragwerk weist zwei Schöpfwalzen auf, die jeweils einer Auftragwalze zugeordnet sind und durch Rotation ihrer Umfangsfläche durch ein Fluidbad Fluid aus dem Fluidbad auf eine Umfangsfläche der zugeordneten und gegensinnig zur Schöpfwalze angetriebenen Auftragwalze übertragen.From the DE 21 01 294 A an applicator for applying a fluid to a material web is known, which has two oppositely and in the web direction driven applicator rollers, between which a material web is guided. The applicator has two scoop rollers, each associated with an applicator roller and transferred by rotation of its peripheral surface by a fluid bath fluid from the fluid bath to a peripheral surface of the associated and opposite to the scoop driven applicator roller.

Die DE 103 37 594 B4 zeigt eine Trennmittelauftragsvorrichtung mit Stellaggregaten zum variablen Verstellen einer Dosierwalze gegen eine Auftragwalze. Die Andrückkräfte der Dosierwalze werden mittels Kraftmesssensoren ermittelt und in Abhängigkeit von der jeweils erforderlichen Trennmittelauftragsmenge geregelt.The DE 103 37 594 B4 shows a release agent application device with actuators for variably adjusting a metering roll against a mandrel. The pressure forces of the metering roller are determined by means of force measuring sensors and regulated as a function of the respectively required release agent application amount.

Die EP 2 062 729 A1 zeigt ein Auftragwerk für lösungsmittelhaltiges Auftragsmaterial, bei dem mittels einer Schöpfwalze das Auftragsmaterial aufgenommen und auf eine Dosierwalze übertragen wird, von der das Auftragsmaterial mittels einer Übertragungswalze auf eine Auftragwalze gelangt, die mit Druckzylindern versehen ist, um das Auftragsmaterial auf eine Materialbahn mittels einer Formatwalze zu übertragen. Sämtliche Walzen sowie der Druckzylinder sind in einem gemeinsamen Maschinenständer gelagert.The EP 2 062 729 A1 shows a applicator for solvent-containing application material, in which by means of a scoop roller, the application material is transferred to a metering roller from which the application material passes by means of a transfer roller on an applicator roller, which is provided with printing cylinders to the application material on a web by means of a form roller transfer. All rollers and the impression cylinder are stored in a common machine stand.

Aus der DE 30 23 114 A1 ist eine Vorrichtung für die Beschichtung eines Bandmaterials mittels einer Anstreichwalze bekannt, wobei das Beschichtungsmaterial in eine zwischen einem Schaber und der Anstreichwalze ausgebildeten Rinne zugeführt wird und von der Anstreichwalze auf ein Bandmaterial übertragen wird.From the DE 30 23 114 A1 a device for coating a strip material by means of a coating roll is known, wherein the coating material in a between a scraper and the coating roller trained channel is supplied and is transferred from the coating roller on a strip material.

Aus der JP S56 7656 A ist ein Walzenauftragwerk bekannt, das zum Auftrag eines Beschichtungsmaterials auf eine Stahlbahn dient, wobei die Walzen in einem gemeinsamen Gestell angeordnet sind.From the JP S56 7656 A For example, a roll applicator is known which serves to apply a coating material to a steel web, wherein the rolls are arranged in a common frame.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Auftragwerk der eingangs genannten Art vorzuschlagen, bei dem die Kontaktkraft zwischen den Auftragwalzen verändert werden kann, ohne dass hierdurch die Relativpositionierung der Auftragwalze gegenüber der zugeordneten Schöpfwalze beeinflusst wird.The present invention is therefore based on the object to propose an applicator of the type mentioned, in which the contact force between the applicator rollers can be changed, without affecting the relative positioning of the applicator roller relative to the associated scoop roller is influenced.

Diese Aufgabe wird durch ein Auftragwerk mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by an applicator with the features of claim 1.

Erfindungsgemäß weist das Auftragwerk zur Einstellung einer zwischen den Auftragwalzen und der Materialbahn wirkenden Kontaktkraft zumindest eine Auftragwalze auf, die mit einer auf die Auftragwalzenachse wirkenden Zustelleinrichtung versehen ist, die mit einer Messeinrichtung zur Messung der Kontaktkraft versehen ist, derart, dass eine Betätigung der Zustelleinrichtung in Abhängigkeit von der gemessenen Kontaktkraft erfolgt.According to the invention, the applicator for setting a force acting between the applicator rollers and the material web contact force at least one applicator roller which is provided with an acting on the applicator roller feed device, which is provided with a measuring device for measuring the contact force, such that actuation of the feed device in Dependence on the measured contact force occurs.

Das erfindungsgemäß ausgestaltete Auftragwerk ermöglicht über die Einstellung der Kontaktkraft einen gleichmäßigen Auftrag von Gleitmittel. Mithin kann durch die Vorgabe einer definierten Kontaktkraft bei konstanter durch die Schöpfwalzen bereitgestellter Fluidmenge ein entsprechend konstanter Gleitmittelauftrag erzeugt werden.The inventively designed applicator allows the adjustment of the contact force a uniform application of lubricant. Consequently, by providing a defined contact force with a constant amount of fluid provided by the scoop rollers, a correspondingly constant lubricant application can be generated.

Insbesondere bei einer elastischen Ausbildung der Oberfläche der Auftragwalzen ermöglicht die Veränderung der Kontaktkraft eine Beeinflussung der zwischen den Auftragwalzen und der Materialbahn ausgebildeten Kontaktfläche und somit eine entsprechende Beeinflussung des Gleitmittelauftrags.Particularly in the case of an elastic design of the surface of the application rollers, the change in the contact force makes it possible to influence the contact surface formed between the application rollers and the material web and thus to influence the lubricant application accordingly.

Erfindungsgemäß ist die Zustelleinrichtung derart ausgeführt, dass ein erstes Gestellteil und ein zweites Gestellteil jeweils eine Auftragwalze mit der zugeordneten Schöpfwalze aufweisen und zur Einstellung der Kontaktkraft ein Stellglied der Zustelleinrichtung vorgesehen ist, das auf einen Gestellteil wirkt, derart, dass die Relativposition der Gestellteile verändert wird, sodass es möglich ist, jeweils eine aus einer Auftragwalze und einer Schöpfwalze gebildete Walzenpaarung als Einheit gegenüber einer zweiten, aus Auftragwalze und Schöpfwalze gebildeten Walzenpaarung zu verstellen.According to the invention, the delivery device is embodied such that a first frame part and a second frame part each have an application roller with the associated scoop roller and an actuator of the delivery device is provided for adjusting the contact force, which acts on a frame part, such that the relative position of the frame parts is changed so that it is possible in each case to adjust a pair of rollers formed from an applicator roller and a scoop roller as a unit with respect to a second roller pair formed from applicator roller and scoop roller.

Eine besonders einfach realisierbare und kompakte Ausführung der Kraftmesseinrichtung wird möglich, wenn zur Ausbildung der Kraftmesseinrichtung zumindest ein Lager der Auftragwalzenachse mit einer Einrichtung zur Messung der Kontaktkraft versehen ist.A particularly easy to implement and compact design of the force measuring device is possible if at least one bearing of the applicator roller axis is provided with a device for measuring the contact force to form the force measuring device.

Besonders vorteilhaft ist es auch, wenn ein zwischen einer Schöpfwalze und einer Auftragwalze ausgebildeter Übergabespalt, der die Menge des von der Schöpfwalze auf die Auftragswalze übergebenen Fluids entscheidend mit beeinflusst, einstellbar ist.It is also particularly advantageous if a transfer gap formed between a scoop roller and an applicator roller, which decisively influences the amount of fluid transferred from the scoop roller to the applicator roller, is adjustable.

Eine besonders genau reproduzierbare Einstellung des Übergabespalts wird möglich, wenn die Zustellungeinrichtung zur Einstellung des Übergabespaltes ein auf die Schöpfwalzenachse wirkendes Stellglied aufweist, das eine radiale Verstellung der Achse gegenüber einem die Lagerung der Achse aufnehmenden Gestellteil des Auftragwerks ermöglicht.A particularly accurate reproducible adjustment of the transfer gap is possible if the delivery device for adjusting the transfer gap has an acting on the scoop roller actuator, which allows a radial adjustment of the axis relative to a storage of the axis receiving frame part of the application.

Um zu verhindern, dass sich beispielsweise ein stabiles Fluidpolster zwischen einem von der Schöpfwalze auf die Auftragwalze übertragenen Gleitmittelauftrag und der Oberfläche der Auftragwalze aufbaut, ist es vorteilhaft, wenn die Schöpfwalzen mit einer Oszillationseinrichtung versehen sind, derart, dass die Schöpfwalzen Oszillationsbewegungen in Richtung ihrer Achse ausführen.In order to prevent, for example, a stable fluid cushion from being built up between a lubricant application transferred from the scoop roller to the application roller and the surface of the application roller, it is advantageous if the scoop rollers are provided with an oscillating device are provided, such that the scoop rollers perform oscillatory movements in the direction of its axis.

Besonders vorteilhaft lässt sich die Ausbildung eines Fluidpolsters zwischen der Oberfläche der Schöpfwalzen mit dem aus dem Fluidbad aufgenommenen Gleitmittelauftrag und der Oberfläche der Auftragwalze dadurch verhindern, dass die Schöpfwalzen an ihrer Umfangsfläche innerhalb eines Fluidtanks, der zur Aufnahme des Fluidbades dient, mit einer Abstreifvorrichtung versehen sind, die eine parallel zur Schöpfwalzenachse verlaufende und oberhalb eines Eintauchumfangs sowie unterhalb der Achse der Schöpfwalze angeordnete Abstreifkante aufweist.Particularly advantageous is the formation of a fluid cushion between the surface of the scoop rollers with the recorded from the fluid bath lubricant application and the surface of the applicator roll prevent it, that the scoop rollers are provided on its peripheral surface within a fluid tank, which serves to receive the fluid bath with a stripping which has a scraper edge running parallel to the scoop roller axis and arranged above an immersion circumference and below the axis of the scoop roller.

Hierdurch ist sichergestellt, dass sich die der Ausbildung von Fluidpolstern entgegenwirkende Abstreifkante in einer Relativposition zur Umfangsfläche der Schöpfwalze in unmittelbarer Nähe zum Übergang zwischen der Walzenoberfläche der Schöpfwalze und der Badoberfläche des Fluidbads befindet, so dass verhindert wird, dass sich eine große Stauwelle im Bereich dieses Übergangs ausbildet, welche das Entstehen eines Fluidpolsters fördern könnte.This ensures that the wiping edge counteracting the formation of fluid pads is in a position relative to the circumferential surface of the scoop roller in the immediate vicinity of the transition between the roller surface of the scoop roller and the bath surface of the fluid bath, thus preventing a large damming wave in the area of this Transition forms, which could promote the emergence of a fluid cushion.

Besonders vorteilhaft lässt sich die Wirkung einer ersten Abstreifvorrichtung verstärken, wenn die Schöpfwalzen oberhalb ihrer Achse mit einer zweiten Abstreifvorrichtung versehen sind, die eine parallel zur Schöpfwalzenachse verlaufende Abstreifkante aufweist.The effect of a first scraper device can be particularly advantageously enhanced if the scoop rollers are provided above their axis with a second scraper device which has a scraper edge running parallel to the scoop roller axis.

Eine weitere Verstärkung der vorteilhaften Wirkung der Abstreifvorrichtungen lässt sich erzielen, wenn die Abstreifvorrichtungen mit einer Oszillationseinrichtung versehen sind, derart, dass die Abstreifvorrichtungen eine Oszillationsbewegung in Richtung ihrer Längsachse ausführen.A further enhancement of the advantageous effect of the stripping devices can be achieved if the stripping devices are provided with an oscillation device, such that the stripping devices perform an oscillatory movement in the direction of their longitudinal axis.

Eine gegenseitige positive Beeinflussung der Oszillationsbewegungen lässt sich erreichen, wenn die Abstreifvorrichtungen derart an die zugeordneten Oszillationseinrichtungen angeschlossen sind, dass die Abstreifvorrichtungen gegensinnige Oszillationsbewegungen ausführen.Mutual positive influence on the oscillatory movements can be achieved if the stripping devices in such a way to the associated Oscillators are connected, that the stripping devices perform opposing oscillatory movements.

Wenn im Einlaufbereich und im Auslaufbereich der Auftragwalzen jeweils eine Umlenkrolle angeordnet ist, deren Relativanordnung zu den Auftragwalzen in horizontaler Richtung veränderbar ist, kann die Menge des Gleitmittelauftrags von den Auftragwalzen auf die Oberfläche der Materialbahn insbesondere durch eine Beeinflussung des zwischen der Materialbahn und den Auftragwalzen ausgebildeten Umschlingungswinkels beeinflusst werden.If in each case a deflection roller is arranged in the inlet region and in the outlet region of the application rollers whose relative arrangement is changeable to the application rollers in the horizontal direction, the amount of Gleitmittelauftrags of the application rollers on the surface of the material web in particular by influencing the formed between the material web and the application rollers Wrap angle can be influenced.

Für eine reproduzierbare Relativanordnung der Umlenkrollen gegenüber den Auftragwalzen können die Umlenkrollen mit einer Wegmesseinrichtung zur Erfassung ihrer horizontalen Position versehen sein.For a reproducible relative arrangement of the deflection rollers relative to the application rollers, the deflection rollers can be provided with a displacement measuring device for detecting their horizontal position.

in a schematic representation one between two application rollers of in Fig. 1 shown applicator according to the prior art guided material web.

Fig. 1 zeigt ein Auftragwerk 10 mit zwei Gestellteilen 11, 12, die auf einer Gestellbasis 13 angeordnet sind, wobei jedes Gestellteil 11, 12 jeweils zur Anordnung einer Auftragwalze 14 und einer der Auftragwalze zugeordneten Schöpfwalze 15 dient. Fig. 1 shows an applicator 10 with two frame parts 11, 12 which are arranged on a frame base 13, wherein each frame part 11, 12 respectively for the arrangement of an applicator roller 14 and one of the applicator roller associated scoop roller 15 is used.

Die Gestellteile 11, 12 weisen jeweils eine Auftragwalzenlagerung 18 sowie eine Schöpfwalzenlagerung 19 auf, die die Ausrichtung und Anordnung einer Auftragwalzenachse 20 zur Schöpfwalzenachse 21 in dem Gestellteil 11 bzw. 12 definieren.The frame parts 11, 12 each have an applicator roller bearing 18 and a scoop roller bearing 19, the orientation and Arrangement of an applicator roll axis 20 to the scoop roller axis 21 in the frame part 11 and 12 define.

Wie ferner aus einem Vergleich der Fig. 1 mit der Fig. 2 zu ersehen ist, die die Gestellteile 11, 12 in veränderter Relativposition gegenüber der Gestellbasis 13 zeigen, ist das Gestellteil 11 gegenüber dem Gestellteil 12 sowie der Gestellbasis 13 mit einer ersten Zustelleinrichtung 22 in vertikaler Richtung verschiebbar. Darüber hinaus ist das zweite Gestellteil 12 gegenüber dem ersten Gestellteil 11 sowie der Gestellbasis 13 mittels einer zweiten Zustelleinrichtung 23 horizontal verschiebbar. Die Zustelleinrichtungen 22 und 23 weisen im Falle des dargestellten Ausführungsbeispiels jeweils eine Längsführung 24 bzw. 25 an der Gestellbasis 13 auf, die mittels einer nicht näher dargestellten Antriebseinrichtung jeweils eine Längsverschiebung des Gestellteils 11 bzw. 12 in vertikaler bzw. horizontaler Richtung gegenüber der Gestellbasis 13 ermöglichen.As further from a comparison of Fig. 1 with the Fig. 2 can be seen, showing the frame parts 11, 12 in a modified relative position relative to the frame base 13, the frame part 11 relative to the frame part 12 and the frame base 13 with a first feed device 22 in the vertical direction. In addition, the second frame part 12 with respect to the first frame part 11 and the frame base 13 by means of a second feed device 23 is horizontally displaceable. The feed devices 22 and 23 have in the case of the illustrated embodiment, in each case a longitudinal guide 24 and 25 on the frame base 13, which by means of a drive device not shown in each case a longitudinal displacement of the frame part 11 and 12 in the vertical or horizontal direction relative to the frame base thirteenth enable.

Wie Fig. 2 ferner zeigt, ist an jedem Gestellteil 11, 12 ein Fluidtank 27 zur Aufnahme eines Fluidbades 28 ausgebildet, wobei über eine nicht näher dargestellte Füllstandsregelung das Niveau einer Badoberfläche 29 im Fluidtank 27 eingestellt wird. Die Schöpfwalzen 15 sind in jedem Gestellteil 11, 12 so angeordnet, dass sie mit einer Teilumfangsfläche in das Fluidbad 28 eintauchen und bei Rotation in Antriebsrichtung 30 an ihrer Umfangsfläche 31 anhaftendes Fluid dem Fluidbad 28 entnehmen. Zur Unterstützung dieser Mitnahme kann die Umfangsfläche 31 mit einer geeigneten Profilierung bzw. Oberflächenstruktur versehen sein, die beispielsweise eine Vielzahl von an der Umfangsfläche 31 ausgebildete Schöpfmulden aufweisen kann.As Fig. 2 Furthermore, a fluid tank 27 for receiving a fluid bath 28 is formed on each frame part 11, 12, whereby the level of a bath surface 29 in the fluid tank 27 is adjusted by means of a filling level control (not shown). The scoop rollers 15 are arranged in each frame part 11, 12 so that they dive into the fluid bath 28 with a partial peripheral surface and remove fluid adhering to its peripheral surface 31 during rotation in the drive direction 30 to the fluid bath 28. To support this entrainment, the circumferential surface 31 may be provided with a suitable profiling or surface structure, which may for example have a plurality of scooping recesses formed on the circumferential surface 31.

Wie in der Fig. 3 dargestellt ist, bildet sich im Bereich eines Übergabespaltes 35 zwischen den Schöpfwalzen 15 und der jeweils zugeordneten Auftragwalze 14, die in einer Antriebsrichtung 32 gegensinnig zur Schöpfwalze 15 angetrieben wird, ein Fluidkeil 45 aus, der infolge der Rotation der Schöpfwalze 15 kontinuierlich mit Fluid aus dem Fluidbad 28 ergänzt wird und dem entsprechend der Rotation der Auftragwalze 14 ständig Fluid entnommen wird, das auf eine Umfangsfläche 34 der Auftragwalze 14 übertragen und von dieser auf eine Bahnunterseite 43 bzw. eine Bahnoberseite 44 einer Materialbahn 37 übertragen wird.Like in the Fig. 3 is shown, formed in the region of a transfer nip 35 between the scoop rollers 15 and the respective associated applicator roller 14, which is driven in opposite directions to the scoop roller 15 in a drive direction 32, a fluid wedge 45, due to the rotation of the scoop roller 15 continuously with fluid from the fluid bath 28 is supplemented and according to the rotation of the applicator roll 14 fluid is constantly removed, which is transferred to a peripheral surface 34 of the applicator roll 14 and transferred from this on a web bottom 43 and a web top 44 of a web 37.

Wie Fig. 1 zeigt, wird im Betrieb des Auftragwerks 10 die Materialbahn 37 durch einen Auftragwalzenspalt 36 zwischen den beiden einander gegenüberliegenden Auftragwalzen 14 hindurchgeführt, wobei in einem Einlaufbereich 38 und einem Auslaufbereich 39 des Auftragwerks jeweils eine horizontal verstellbare Umlenkrolle 40, 41 angeordnet ist, die eine Beeinflussung des Einlaufwinkels α bzw. eines Auslaufwinkels β ermöglichen, der zwischen einer Walzenspaltebene 42 und der Materialbahn 37 im Einlaufbereich 38 bzw. im Auslaufbereich 39 ausgebildet ist. Hiermit lässt sich auch, wie in Fig. 2 dargestellt ist, insbesondere im Zusammenwirken mit einer entsprechenden Relativposition der Gestellteile 11, 12 gegenüber der Gestellbasis 13, die Größe eines zwischen einer Bahnunterseite 43 bzw. einer Bahnoberseite 44 und der jeweils zugeordneten Auftragwalze 14 ausgebildeten Umschlingungswinkels bestimmen, der maßgeblich ist für die Größe der zwischen der Bahnunterseite 43 bzw. der Bahnoberseite 44 und der jeweiligen Auftragswalze 14 ausgebildeten Kontaktfläche.As Fig. 1 shows, in the operation of the applicator 10, the web 37 is passed through an applicator nip 36 between the two opposing applicator rollers 14, wherein in a lead-in area 38 and a discharge area 39 of the applicator respectively a horizontally adjustable guide roller 40, 41 is arranged, which influences the Allow inlet angle α and a discharge angle β, which is formed between a nip plane 42 and the material web 37 in the inlet region 38 and in the outlet region 39. This can also be, as in Fig. 2 is shown, in particular in cooperation with a corresponding relative position of the frame parts 11, 12 relative to the frame base 13, determine the size of a formed between a web base 43 and a web top 44 and the respectively associated applicator roller 14 wrap angle, which is decisive for the size of between the web bottom 43 and the web top 44 and the respective applicator roll 14 formed contact surface.

Wie in Fig. 3 schematisch dargestellt, bildet sich zwischen der Bahnunterseite 43 bzw. der Bahnoberseite 44 der Materialbahn 37 und der jeweils gegen die Bahnunterseite 43 bzw. der Bahnoberseite 44 anliegenden Auftragwalze 14 eine Kontaktkraft F aus.As in Fig. 3 shown schematically, forms between the web bottom 43 and the top web 44 of the web 37 and the respectively against the web bottom 43 and the top web 44 applied application roller 14, a contact force F from.

Die Größe der Kontaktkraft F kann vorzugsweise durch eine in die Auftragwalzenlagerung 18 integrierte, hier nicht näher dargestellte Kraftmesseinrichtung ermittelt und als Stellgröße für die Zustelleinrichtung 22 oder 23 verwendet werden, so dass etwa bei Überschreitung eines für die Kontaktkraft F definierten Sollwertes eine Vergrößerung des Achsabstands a zwischen den Auftragwalzen 14 erfolgt. Hierdurch kann eine beispielsweise in Versuchen ermittelte Kontaktkraft F, die für definierte Parameter, wie Walzbandgeschwindigkeit und Fluidviskosität, einen möglichst gleichmäßigen Fluidauftrag auf die Bahnunterseite 43 bzw. Bahnoberseite 44 der Materialbahn 37 ermöglicht, als Referenz für den Achsabstand a dienen, so dass also die Einstellung des Achsabstands a in Abhängigkeit von der Kontaktkraft erfolgen kann.The size of the contact force F can preferably be determined by an integrated into the applicator roller bearing 18, not shown force measuring device and used as a manipulated variable for the feed device 22 or 23, so that when exceeding a defined value for the contact force F, an increase in the axial distance a takes place between the applicator rollers 14. As a result, a determined, for example, in experiments contact force F, the Defined parameters, such as rolling belt speed and fluid viscosity, as uniform as possible fluid application to the web bottom 43 and web top 44 of the material web 37 allows to serve as a reference for the axial distance a, so that so the adjustment of the axial distance a can be done depending on the contact force.

Wie ferner den Fig. 1 und 2 zu entnehmen ist, sind im Umfangsbereich der Schöpfwalzen 15 Abstreifvorrichtungen 47, 48 vorgesehen, wobei die untere Abstreifvorrichtung 47 mit ihrer Abstreifkante 49, die sich parallel zur Schöpfwalzenachse 21 erstreckt, oberhalb eines Eintauchumfangs 50 der Schöpfwalze 15 am Fluidtank 27 angeordnet ist. Die Abstreifvorrichtung 48 befindet sich mit ihrer ebenfalls parallel zur Schöpfwalzenachse 21 verlaufenden Abstreifkante 51 oberhalb der Schöpfwalzenachse 21.How further the Fig. 1 and 2 it can be seen, scrapers 47, 48 are provided in the peripheral region of the scoop rollers 15, wherein the lower scraper 47 is arranged with its scraper edge 49 which extends parallel to the scoop roller axis 21, above a Eintauchumfangs 50 of the scoop roller 15 on the fluid tank 27. The scraper 48 is located with its also parallel to the scoop roller axis 21 extending scraper edge 51 above the scoop roller axis 21st
