Description

Die Erfindung betrifft eine Vorrichtung zur Benetzung einer Warenbahn mit einer Flüssigkeit, wobei die Warenbahn in einer Laufrichtung durch die Vorrichtung hindurchgeführt wird, umfassend Führungsmittel zur Führung der Warenbahn und Auftragsmittel zum Aufbringen der Flüssigkeit auf die Warenbahn.The invention relates to a device for wetting a web with a liquid, wherein the web is passed in a running direction through the device, comprising guide means for guiding the web and application means for applying the liquid to the web.

Es ist bekannt, Warenbahnen, beispielsweise eine Folie, ein Vlies, ein Papier oder ein textiles Gewirke, mit im Allgemeinen flüssigen Chemikalien zu benetzen, um die Warenbahn mit einer funktionalen Ausrüstung zu versehen. Hierbei kann es sich beispielsweise um eine Färbung, eine Imprägnierung, eine Fleckenschutzbeschichtung, eine Nanobeschichtung, eine antibakterielle Beschichtung oder dergleichen handeln.It is known to wet webs, such as a film, a nonwoven, a paper or a textile knitted fabric, with generally liquid chemicals to provide the web with a functional equipment. This may be, for example, a dyeing, an impregnation, a stain-proof coating, a nano-coating, an antibacterial coating or the like.

Ein derartiges Verfahren sowie eine entsprechende Vorrichtung sind beispielsweise aus der DE 10 2006 038 339 A1 bekannt. Hier wird die zu benetzende Warenbahn über eine rotierende Auftragswalze geführt, welche teilweise in eine Chemikalienwanne eingetaucht ist und mittels welcher die Chemikalie aus der Wanne auf die Warenbahn aufgebracht wird. Zwei Leitwalzen, die vor bzw. hinter der Auftragswalze angeordnet sind, dienen der Führung der Warenbahn über die Auftragswalze.Such a method and a corresponding device are for example from DE 10 2006 038 339 A1 known. Here, the web to be wetted is guided over a rotating applicator roll, which is partially immersed in a chemical tank and by means of which the chemical is applied from the tub to the web. Two guide rolls, which are arranged in front of and behind the applicator roll, serve to guide the fabric web over the applicator roll.

Ein Nachteil der aus dem Stand der Technik bekannten Vorrichtungen liegt darin, dass es abhängig vom Kontaktwinkel zwischen der Warenbahn auf der Auftragswalze, der Warenbahngeschwindigkeit, der Warenbahngrammatur, der Auftragswalzengeschwindigkeit und der Viskosität der benetzenden Substanz auf dem Scheitelpunkt der Auftragswalze zum Durchdringen der Substanz durch die Warenbahn kommen kann. In Abhängigkeit von den oben genannten Parametern kann das Maß der Durchdringung so stark sein, dass nicht unerhebliche Mengen der benetzenden Flüssigkeit auf der der Auftragswalze abgewandten Seite der Warenbahn aus dieser heraustreten, in Warenbahnlaufrichtung in die Umgebung geschleudert werden und so zu einem Aerosolnebel führen.A disadvantage of the known from the prior art devices is that it depends on the contact angle between the web on the applicator roll, the web speed, the web grammage, the application roller speed and the viscosity of the wetting substance at the apex of the applicator roll for penetrating the substance through the Web can come. Depending on the above parameters, the degree of penetration can be so strong that not inconsiderable amounts of the wetting liquid on the side facing away from the applicator roll of the web emerge from this, be thrown in the web direction of travel into the environment and thus lead to an aerosol mist.

Dieser Aerosolnebel ist in vielfacher Hinsicht nachteilig. So setzt er sich auf den umliegenden Oberflächen der Anlage ab, wodurch diese verschmutzt und je nach Chemikalie erheblich angegriffen werden können. Eine derartige Kontamination der Anlage kann auf Dauer die Anlagensicherheit herabsetzen. Das Absetzen auf Böden und Treppen führt zu rutschigen Oberflächen, die ein Verletzungsrisiko für an der Vorrichtung arbeitende Menschen bedeuten. Diese sind darüber hinaus einer unter Umständen gesundheitsschädlichen Verunreinigung der Atemluft durch den Aerosolnebel ausgesetzt. Flüssigkeit, die sich auf den umliegenden Anlagenteilen, insbesondere auf über der Warenbahn verlaufenden Traversen, absetzt, kann wieder auf die Warenbahn herunter tropfen und so die Produktqualität negativ beeinflussen. Schließlich bedeutet der in die Umgebung entweichende Aerosolnebel einen erheblichen Kostenmehraufwand, da bis zu 30 % der aufzutragenden Substanz durch die Warenbahn hindurchtreten und sich verflüchtigen und so nicht für die Benetzung verwendet werden können.This aerosol mist is disadvantageous in many respects. Thus, it settles on the surrounding surfaces of the system, which makes them dirty and can be significantly attacked, depending on the chemical. Such contamination of the system can permanently reduce plant safety. Settling on floors and stairs leads to slippery surfaces that pose a risk of injury to people working on the device. These are also exposed to a potentially harmful contamination of the air through the aerosol mist. Liquid that settles on the surrounding parts of the installation, in particular on trusses running over the material web, can drip down onto the material web and thus adversely affect product quality. Finally, the escaping into the environment aerosol mist means a significant cost overhead, since up to 30% of the substance to be applied to pass through the web and volatilize and can not be used for wetting.

Bislang werden oberhalb der Warenbahn im Bereich der Benetzung Absaughauben zur Absaugung des Aerosolnebels eingesetzt, wie z.B. in der DE 10 2008 040 414 A1 beschrieben, welche jedoch einen größeren anlagentechnischen Aufwand darstellen und auch nur mit einem gewissen baulich bedingten Abstand zur Warenbahn installiert werden können. Aus diesem Grund können derartige Vorrichtungen nicht verhindern, dass sich in unmittelbarer Umgebung der benetzten Warenbahn Flüssigkeit verflüchtigt und/oder auf Maschinenteilen absetzt. Auch kann Flüssigkeit, die sich in den Randbereichen der Absaughaube absetzt, wieder auf die Warenbahn zurücktropfen. Zudem kann die abgesaugte Flüssigkeit in aller Regel nicht mehr zur Benetzung verwendet werden, so dass der Verlust an derartiger Flüssigkeit nach wie vor erheblich ist.So far, suction hoods for extracting the aerosol mist are used above the web in the field of wetting, such as in the DE 10 2008 040 414 A1 described, however, which represent a major plant outlay and only with a certain structural condition Distance to the web can be installed. For this reason, such devices can not prevent liquid volatilizes in the immediate vicinity of the wetted web and / or deposited on machine parts. Also, liquid that settles in the edge regions of the suction hood, drip back onto the web. In addition, the extracted liquid usually can not be used for wetting, so that the loss of such liquid is still significant.

Die US 6 264 743 B1 beschreibt eine Auftragsvorrichtung mit einer mit Unterdruck beaufschlagten Stützwalze für die Warenbahn, welche überschüssige Flüssigkeit aufnimmt.The US Pat. No. 6,264,743 B1 describes an applicator with a pressurized backing roller for the web, which receives excess liquid.

Aus der DE 1 063 892 B ist es bekannt, Klebstoffspritzer einer Auftragsvorrichtung auf einer mechanisch bewegbaren Bahn aufzufangen.From the DE 1 063 892 B It is known to collect adhesive splashes of a coating device on a mechanically movable web.

Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zur Benetzung einer Warenbahn mit einer Flüssigkeit bereitzustellen, welche die oben genannten Nachteile des Standes der Technik überwindet.The object of the present invention is therefore to provide a device for wetting a web with a liquid, which overcomes the above-mentioned disadvantages of the prior art.

Die Aufgabe wird gelöst durch eine Vorrichtung mit den Merkmalen des Patentanspruches 1.The object is achieved by a device having the features of claim 1.

Bevorzugte Ausführungsbeispiele und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Preferred embodiments and further developments of the invention are subject of the dependent claims.

Die erfindungsgemäße Vorrichtung zur Benetzung einer Warenbahn mit einer Flüssigkeit zeichnet sich dadurch aus, dass ein auf die zu benetzende Warenbahn auflegbarer Spritzschutz vorgesehen ist und die Warenbahn in einer Laufrichtung zwischen den Auftragsmitteln und dem Spritzschutz hindurchführbar ist.The device according to the invention for wetting a material web with a liquid is characterized in that a spray protection which can be placed on the material web to be wiped is provided and the material web can be guided in a running direction between the application means and the splashguard.

Mit anderen Worten sieht die Erfindung eine mechanische Schutzvorrichtung vor, unter der die Warenbahn über die Auftragsmittel läuft und durch welche ein sich in die Umgebung der Warenbahn ausbreitender Aerosolnebel bereits an der Entstehungsstelle wirksam verhindert werden kann. Hierzu ist es erfindungsgemäß vorgesehen, dass der Spritzschutz unmittelbar auf der Warenbahn aufliegt, so dass eine Verflüchtigung der benetzenden Chemikalie und damit ein Verlust an Auftragsflüssigkeit vollständig verhindert werden kann. Durch den auf der Warenbahn aufliegenden Spritzschutz wird vielmehr eine gleichmäßige, homogene Tränkung der Warenbahn bewirkt. Flüssigkeit, die durch die Warenbahn hindurchtritt, befeuchtet die der Warenbahn zugewandte Seite des Spritzschutzes, dieser wird jedoch sofort von der nachlaufenden Warenbahn abgereinigt. In Abhängigkeit von der Warenbahndicke kann die fertig benetzte Warenbahn aufgrund der Durchdringung der benetzenden Chemikalie auf beiden Seiten gleiche Eigenschaften aufweisen.In other words, the invention provides a mechanical protection device under which the material web runs over the application means and by means of which an aerosol mist which spreads out into the environment of the material web can be effectively prevented already at the point of origin. For this purpose, it is provided according to the invention that the splash guard rests directly on the web, so that volatilization of the wetting chemical and thus a loss of application liquid can be completely prevented. By resting on the fabric splash guard rather a uniform, homogeneous impregnation of the web is effected. Liquid that passes through the web, moistens the web of the side facing the splash guard, but this is immediately cleaned from the trailing web. Depending on the web thickness, the finished wetted web due to the penetration of the wetting chemical on both sides have the same properties.

Bei einer Ausführung der Erfindung ist als Auftragsmittel mindestens eine Auftragswalze vorgesehen, welche in einer die benetzende Flüssigkeit enthaltenden Wanne rotiert und über die die Warenbahn hinweg geführt wird. Durch in bestimmten Bereichen auf die Auftragswalze aufgebrachte Abdeckstreifen kann auch ein Streifenauftrag realisiert werden. Grundsätzlich sind auch andere Auftragsmechanismen, beispielsweise eine Sprühauftrag, möglich.In one embodiment of the invention, at least one applicator roll is provided as the application means, which rotates in a tub containing the wetting liquid and over which the fabric web is passed away. By applied in certain areas on the applicator cover strips can also be a strip order can be realized. In principle, other application mechanisms, for example a spray application, are also possible.

Als Führungsmittel sind vorzugsweise Führungswalzen sowie mindestens eine Tauchwalze vorgesehen, mittels derer die Warenbahn geradlinig und straff über die Auftragsmittel, insbesondere über die Auftragswalze, hinweg geführt werden kann. Die Tauchwalze ist dabei in der Regel höhenverstellbar, so dass ihre Position so gewählt werden kann, dass die Warenbahn Kontakt zur Auftragswalze hat.As guide means preferably guide rollers and at least one dipping roller are provided, by means of which the web can be guided in a straight line and tightly over the application means, in particular over the applicator roll. The fountain roller is usually adjustable in height, so that their position can be chosen so that the web has contact with the applicator roll.

Der erfindungsgemäße Spritzschutz ist bei einer Ausführung der Erfindung als Folie ausgebildet, welche eine hinreichende Chemikalienresistenz aufweist. Die Folie ist besonders bevorzugt aus Polytetrafluorethylen (PTFE, beispielsweise bekannt als Teflon® der Firma DuPont) gefertigt. Derartige Folien sind flüssigkeitsundurchlässig, so dass im Bereich der Abdeckung der Warenbahn durch die Folie keinerlei benetzende Chemikalie austreten kann. Sie können sich äußerst flexibel an die Warenbahn anpassen und sind unaufwändig in der Herstellung und Bereitstellung. PTFE zeichnet sich darüber hinaus durch eine sehr hohe chemische Beständigkeit aus und wird selbst von aggressiven Chemikalien nicht angegriffen. Es hat weiterhin einen sehr geringen Reibungskoeffizienten, so dass die PTFE-Folie der bewegten Warenbahn trotz engen Anliegens keinen übermäßigen Widerstand entgegenstellt und nur geringem Verschleiß unterliegt. Aufgrund seiner geringen Oberflächenspannung ist PTFE nur schwer zu benetzen, so dass, wie bereits oben ausgeführt, durch die Warenbahn hindurchgetretene Flüssigkeit unmittelbar von der nachlaufenden Warenbahn abgereinigt wird und nicht dauerhaft an der Folie anhaftet. Neben der Ausbildung des erfindungsgemäßen Spritzschutzes aus einer PTFE-Folie kommen auch andere auf Basis von PTFE gefertigte Materialien in Betracht, z.B. mit PTFE beschichtete Gewebebahnen oder aus PTFE-Folienstreifen gewebte Gewebe und dergleichen.The splash guard according to the invention is formed in one embodiment of the invention as a film which has a sufficient resistance to chemicals. The film is particularly preferably made of polytetrafluoroethylene (PTFE, for example, known as Teflon ® from DuPont) is manufactured. Such films are liquid impermeable, so that in the region of the cover of the web through the film no wetting chemical can escape. They can adapt extremely flexibly to the web and are uncomplicated to manufacture and provide. PTFE is also characterized by a very high chemical resistance and is not attacked even by aggressive chemicals. It also has a very low coefficient of friction, so that the PTFE film of the moving web despite tight concerns against excessive resistance and is subject to little wear. Due to its low surface tension, PTFE is difficult to wet, so that, as already stated above, liquid that has passed through the fabric web is directly cleaned off the trailing material web and does not permanently adhere to the film. In addition to the formation of the splash protection of a PTFE film according to the invention also come Other PTFE-based materials are contemplated, eg PTFE-coated fabric webs or woven PTFE film webs and the like.

Gemäß einem Vorschlag der Erfindung erstreckt sich der Spritzschutz, welcher vorzugsweise als Folie ausgebildet ist, in Laufrichtung L der Warenbahn über den Bereich, in dem die Benetzung erfolgt, d.h. bei Verwendung einer Auftragswalze im allgemeinen über den Scheitelpunkt der Auftragswalze, sowie einen diesem vorangehenden und einen an diesen anschließenden Bereich von z. B. jeweils höchstens 1 m, vorzugsweise jeweils höchstens 0,75 m, sowie mindestens über die gesamte Breite der Warenbahn. Auf diese Weise wird sichergestellt, dass aus einem definierten Bereich um die Auftragsmittel herum keine Flüssigkeit von der Warenbahn weggeschleudert werden kann.According to one proposal of the invention, the splash guard, which is preferably formed as a film, extends in the running direction L of the web over the area in which the wetting takes place, i. when using an applicator roll in general on the vertex of the applicator roll, as well as a preceding this and an adjoining this range of z. B. in each case at most 1 m, preferably in each case at most 0.75 m, as well as at least over the entire width of the web. In this way, it is ensured that no liquid can be thrown off the material web from a defined area around the application medium.

Besonders bevorzugt ist eine Ausführung der Erfindung, bei der der Spritzschutz durch Haltemittel auf der Warenbahn gehalten wird. Hierbei kann es sich beispielsweise um mindestens zwei Hohlprofile handeln, die sich quer zur Lauf richtung L der Warenbahn erstrecken und zwischen denen der Spritzschutz an seinen beiden Enden eingespannt ist. Die Haltemittel sind bevorzugt höhenverstellbar, so dass durch entsprechende Positionierung der Haltemittel die Folie gespannt und auf die laufende Warenbahn gedrückt bzw. zur Erhöhung der Spannung leicht in diese hinein gedrückt werden kann.Particularly preferred is an embodiment of the invention in which the splash guard is held by retaining means on the web. This may be, for example, at least two hollow profiles extending transversely to the direction L of the web and between which the splash guard is clamped at both ends. The holding means are preferably height-adjustable, so that by appropriate positioning of the holding means, the film can be stretched and pressed onto the running web or easily to increase the voltage can be pressed into it.

Darüber hinaus wird durch die Haltemittel der Verbund aus Warenbahn und Folie auf die Auftragswalze gedrückt, so dass ein konstanter Anpressdruck auf die Auftragswalzenoberfläche erzeugt wird und eine gleichmäßige Benetzung der Warenbahn erfolgen kann, ohne dass sich Toträume zwischen Auftragswalze, Warenbahn und Folie bilden oder die Warenbahn auf der Auftragswalze zu flattern beginnen kann.In addition, is pressed by the holding means of the composite of web and film on the applicator roll, so that a constant contact pressure is generated on the applicator roll surface and a uniform wetting of the web can be done without forming dead spaces between applicator roll, web and film or the web can start to flutter on the applicator roll.

Bei einer solchen Ausgestaltung der Erfindung ist es auch möglich, die als Spritzschutz dienende Folie lediglich auf die Warenbahn aufzulegen (hydrophobe Produktion) oder durch entsprechende Justierung der Haltemittel einen definierten Anpressdruck auf die Warenbahn zu erzeugen (hydrophile Produktion).In such an embodiment of the invention, it is also possible to hang the film serving as a splash protection only on the web (hydrophobic production) or by appropriate adjustment of the holding means to produce a defined contact pressure on the web (hydrophilic production).

Im Folgenden wird die Erfindung anhand eines Ausführungsbeispieles und unter Bezugnahme auf die beigefügte Zeichnung näher erläutert. Es zeigt:

Figur 1
eine schematische Darstellung der erfindungsgemäßen Vorrichtung.
In the following the invention will be explained in more detail with reference to an embodiment and with reference to the accompanying drawings. It shows:
FIG. 1
a schematic representation of the device according to the invention.

Die in Figur 1 im Ganzen mit 1 bezeichnete Vorrichtung zur Benetzung einer Warenbahn mit einer Flüssigkeit umfasst Führungswalzen 6 sowie eine höhenverstellbar gemäß Pfeilen H2 geführte Tauchwalze 7, durch welche eine Warenbahn 2 mit einer definierten Warenbahngeschwindigkeit in einer Laufrichtung L über eine Auftragswalze 5 geführt wird. Die Auftragswalze 5 rotiert in einer mit einer Chemikalie 3 gefüllten Wanne 9, in die sie teilweise eintaucht. Die Chemikalie 3 dient der Imprägnierung der Warenbahn 2 und wird durch Kontaktberührung im Bereich des Scheitelpunktes S der Auftragswalze 5 auf die Warenbahn 2 übertragen.In the FIG. 1 Guiding rollers 6, as well as a height-adjustable dipping roller 7 guided in a height-adjustable manner according to arrows H2, through which a web 2 is guided with a defined web speed in a running direction L over an applicator roller 5, are indicated overall by 1 for wetting a web. The applicator roll 5 rotates in a filled with a chemical 3 tub 9, in which it partially immersed. The chemical 3 is used to impregnate the web 2 and is transmitted to the web 2 by contact contact in the region of the vertex S of the applicator roll 5.

Auf der der Auftragswalze 5 abgewandten Seite der Warenbahn 2 liegt ein als Folie 4 ausgebildeter Spritzschutz aus Polytetrafluorethylen (PTFE) auf der Warenbahn 2 auf. Die Dicke der Folie 4 beträgt beispielsweise 0,1 mm - 1 mm und ist in Figur 1, insbesondere im Verhältnis zur Dicke der Warenbahn 2, nicht maßstabsgetreu dargestellt. Die Folie 4 erstreckt sich in Laufrichtung L der Warenbahn 2 über den Bereich des Scheitelpunktes S der Auftragswalze 5, in dem die Benetzung erfolgt, sowie einen diesem vorangehenden und einen an diesen anschließenden Bereich von jeweils 0,5 m. Quer zur Laufrichtung L erstreckt sich die Folie 4 über die gesamte Breite der Warenbahn 2.On the applicator roller 5 side facing away from the web 2 is formed as a foil 4 splash guard made of polytetrafluoroethylene (PTFE) on the web 2 on. The thickness of the film 4 is for example 0.1 mm - 1 mm and is in FIG. 1 , in particular in relation to the thickness of the web 2, not shown to scale. The film 4 extends in the running direction L of the web 2 over the region of the apex S of the applicator roll 5, in which the wetting takes place, as well as a preceding this and an adjoining this range of 0.5 m. Transverse to the direction L, the film 4 extends over the entire width of the web. 2

Die Folie 4 ist an ihren beiden den Führungswalzen 6 bzw. der Tauchwalze 7 zugewandten Enden in ebenfalls quer zur Laufrichtung L verlaufende Haltemittel 8 eingespannt, welche als Hohlprofile ausgebildet sind. Durch diese wird die Folie 4 auf der Warenbahn 2 gehalten. Zu diesem Zweck sind die Haltemittel 8 höhenverstellbar gemäß Pfeilen H1, H3 ausgebildet, so dass die Folie 4 zunächst an die Warenbahn 2 herangeführt und dann auf die Warenbahn 2 gedrückt bzw. zur Verbesserung der Spannung leicht in diese hinein gedrückt werden kann. Die Höhenverstellung kann auf beide Haltemittel 8 gleichermaßen wirken oder jedem Haltemittel 8 ist eine eigene, unabhängige Höhenverstellung zugeordnet. Darüber hinaus wird der Verbund aus Folie 4 und Warenbahn 2 durch die Haltemittel 8 mit konstantem Anpressdruck auf die Auftragswalze 5 gedrückt. Hierdurch wird eine gleichmäßige Benetzung der Warenbahn 2 mit der Chemikalie 3 ermöglicht, ohne dass sich Toträume zwischen Auftragswalze 5, Warenbahn 2 und Folie 4 bilden, in denen sich Flüssigkeit sammeln könnte. Diese Betriebsweise wird als hydrophile Produktion bezeichnet.The film 4 is clamped at its two ends facing the guide rollers 6 and the fountain roller 7 in also transverse to the direction L extending holding means 8, which are formed as hollow profiles. Through this, the film 4 is held on the web 2. For this purpose, the holding means 8 are height-adjustable according to arrows H1, H3 formed, so that the film 4 is first brought to the web 2 and then pressed onto the web 2 or can be easily pressed into this to improve the voltage. The height adjustment can equally on both holding means 8 act or each holding means 8 is assigned its own, independent height adjustment. In addition, the composite of film 4 and web 2 is pressed by the holding means 8 with constant contact pressure on the applicator roll 5. As a result, a uniform wetting of the web 2 with the chemical 3 is made possible, without creating dead spaces between the applicator roll 5, web 2 and film 4, in which liquid could collect. This mode of operation is referred to as hydrophilic production.

Anteile der Chemikalie 3, welche im Bereich der Auftragswalze 5 durch die Warenbahn 2 hindurchtreten, werden durch die Folie 4 daran gehindert, sich von der Warenbahn 2 zu lösen und in die Umgebung überzugehen. Auf diese Weise werden Kontaminationen der umgebenden Anlagenbauteile, des Fußbodens sowie der Raumluft vermieden und es können erhebliche Mengen der Chemikalie 3 eingespart werden. Gleichzeitig kann auf Absaugvorrichtungen zur Absaugung des Aerosolnebels verzichtet werden, was die Anlagentechnik vereinfacht.Components of the chemical 3, which pass through the web 2 in the area of the applicator roll 5, are prevented by the film 4 from detaching from the web 2 and passing into the environment. In this way, contamination of the surrounding plant components, the floor and the room air are avoided and significant amounts of the chemical 3 can be saved. At the same time can be dispensed with suction for suction of the aerosol mist, which simplifies the system technology.

In Abwandlung der Betriebsweise gemäß Figur 1 können die Haltemittel 8 und auch die üblicherweise höhenverstellbare Tauchwalze 7 so einjustiert werden, dass die Warenbahn 2 geradlinig über die Auftragswalze 5 verläuft, wobei jedoch die als Spritzschutz dienende Folie 4 nach wie vor Oberflächenkontakt zur Warenbahn 2 hält. Diese Betriebsstellung wird auch als hydrophobe Produktion bezeichnet.In a modification of the operation according to FIG. 1 For example, the holding means 8 and also the usually height-adjustable dip roller 7 can be adjusted so that the web 2 runs in a straight line over the applicator roll 5, but the film 4 serving as a splash guard still maintains surface contact with the web 2. This operating position is also referred to as hydrophobic production.

Zusammenfassend wird durch die vorgestellte Erfindung eine Vorrichtung bereitgestellt, welche die Entstehung eines Aerosolnebels bei der Benetzung einer Warenbahn mit einer Flüssigkeit sowie sämtliche damit verbundenen Nachteile verhindert und so insbesondere zu einer deutlichen Einsparung an Benetzungsflüssigkeit führt.In summary, a device is provided by the presented invention, which prevents the formation of an aerosol mist in the wetting of a web with a liquid and all the disadvantages associated therewith and thus leads in particular to a significant saving in wetting liquid.

Ein besonderer Vorteil der erfindungsgemäßen Vorrichtung liegt darüber hinaus in ihrer Flexibilität sowie in der einfachen Nachrüstbarkeit. So kann der Spritzschutz ohne großen Aufwand an unterschiedliche Warenbahnabmessungen angepasst und in verschiedenste Anlagentypen, auch nachträglich, eingebaut werden.A particular advantage of the device according to the invention lies in its flexibility and ease of retrofitting. Thus, the splash guard can be easily adapted to different web dimensions and installed in a variety of plant types, even subsequently.
