Vliesbahnen aufgebracht werden. Avivagen meint beispielsweise Netzmittel, vor allem Tenside und ihre Mischungen, die bevorzugt in Form von Lösungen oder Emulsionen auf die Warenbahn aufgebracht werden. Die Erfindung bezieht sich insbesondere auf den streifenförmigen Auftrag der fluiden Medien auf eine Warenbahn.Device for applying fluid media to a web, - having a job surface over which the web is guided, so that in the contact areas between application surface and web, the fluid medium can be applied to the web and wherein a plurality of cover is provided, which cover Cover covering areas on the application surface so that there is no contact between the material web and the application surface in these covering areas. In the context of the invention, fluid media means, in particular, liquid media and, in particular, lubricants, which are preferably applied to nonwovens or nonwoven webs. Avivagen means, for example wetting agents, especially surfactants and their mixtures, which are preferably applied in the form of solutions or emulsions on the web.

Eine Vorrichtung der eingangs genannten Art ist aus der Praxis grundsätzlich bekannt. Bei dieser Vorrichtung wird mit einer rotierenden Auftragswalze gearbeitet, über die die Warenbahn geführt wird. Auf der Auftragswalze sind streifenförmige Abdeckelemente angeordnet, so dass ein streifenförmiger Auftrag der fluiden Medien bzw. der Avivagen auf die Warenbahn stattfindet. Bei einer aus den Dokument EP 0 997 576 A bekannten Vorrichtung ist es auch bereits bekannt die Abdeckelemente in einem gewissen Ausmaß zu verschieben, um die Positionierung des streifenförmigen Auftrags zu verändern. Wenn aber die Breite des Abdeckbereiches verändert werden soll müssen Abdeckelemente unterschiedlicher Breite in relativ aufwendiger Weise gegeneinander ausgetauscht werden. Diese bekannten Vorrichtungen zeichnen sich deshalb durch eine geringe Flexibilität bzw. Variabilität aus. Im Übrigen beeinflusst die weitere Bearbeitung der Warenbahn, insbesondere die thermische und/oder mechanische und/oder chemische Bearbeitung der Warenbahn, die Position und auch die Breite der Auftragsbereiche bzw. Auftragsstreifen. Die wenig flexible Einstellung der Abdeckbereiche auf die jeweiligen Erfordernisse bedingt hier weitere Nachteile.A device of the type mentioned is basically known from practice. In this device, working with a rotating applicator roll over which the web is guided. On the applicator roll strip-shaped cover elements are arranged so that a strip-like application of the fluid media or the lubricant takes place on the web. At one from the document EP 0 997 576 A known device, it is also already known to move the cover to some extent to change the positioning of the strip-shaped job. If, however, the width of the covering area is to be changed, covering elements of different widths must be exchanged for one another in a relatively complex manner. These known devices are therefore characterized by a low flexibility or variability. Incidentally, the further processing of the web, in particular the thermal and / or mechanical and / or chemical processing of the web, influences the position and also the width of the application areas or application strips. The less flexible adjustment of the coverage areas to the respective requirements requires further disadvantages here.

Zur Lösung dieses technischen Problems lehrt die Erfindung eine Vorrichtung zur Aufbringung von fluiden Medien auf eine Warenbahn, - mit einer Auftragsfläche, über welche Auftragsfläche die Warenbahn geführt wird, so dass in den Kontaktbereichen zwischen Auftragsfläche und Warenbahn das fluide Medium auf die Warenbahn aufbringbar ist,
wobei eine Mehrzahl von Abdeckelementen vorgesehen ist, welche Abdeckelemente flächige Abdeckbereiche auf der Auftragsfläche abdecken, so dass in diesen Abdeckbereichen kein Kontakt zwischen Warenbahn und Auftragsfläche stattfindet,
wobei die Abdeckelemente auf der Auftragsfläche verschiebbar sind, wobei eine Verstelleinrichtung vorgesehen ist, die eine Mehrzahl von Anschlusselementen aufweist, wobei an jedes dieser Anschlusselemente ein Abdeckelement anschließbar ist
und wobei die Anschlusselemente mit den jeweils angeschlossenen Abdeckelementen mittels der Verstelleinrichtung mit der Maßgabe verschiebbar sind, dass zumindest zwei Abdeckelemente unmittelbar benachbart oder überlappend auf der Auftragsfläche positionierbar sind.To solve this technical problem, the invention teaches a device for applying fluid media to a web, with an application surface over which application surface the web is guided so that the fluid medium can be applied to the web in the contact areas between application surface and web,

wherein the cover elements are displaceable on the application surface, wherein an adjusting device is provided which has a plurality of connection elements, wherein a cover element can be connected to each of these connection elements
and wherein the connection elements with the respectively connected cover elements are displaceable by means of the adjusting device with the proviso that at least two cover elements can be positioned directly adjacent or overlapping on the application surface.

Als Warenbahn kann eine gewebte oder eine ungewebte Warenbahn eingesetzt werden. Nach einer bevorzugten Ausführungsform der Erfindung handelt es sich bei der Warenbahn um eine Vliesbahn bzw. um einen Vliesstoff, der insbesondere aus Filamenten aus thermoplastischem Kunststoff besteht. Grundsätzlich kann die erfindungsgemäße Vorrichtung aber auch zum Auftragen des fluiden Mediums auf andere Warenbahnen eingesetzt werden. - Mit fluiden Medien sind im Rahmen der Erfindung insbesondere flüssige Medien gemeint, vor allem Avivagen bzw. Aviviermittel, die zur Einstellung bzw. zur Änderung der Eigenschaften der Warenbahn auf die Warenbahn aufgebracht werden. Wie oben bereits dargelegt kann es sich hierbei um Netzmittel, insbesondere um Tenside und ihre Mischungen handeln, die bevorzugt in Form von Lösungen oder Emulsionen aufgebracht werden. Fluides Medium meint dann eine solche Lösung bzw. Emulsion. Prinzipiell können aber auch andere fluide bzw. flüssige Medien auf die Warenbahn aufgetragen werden.As a web, a woven or a nonwoven web can be used. According to a preferred embodiment of the invention, the web is a nonwoven web or a nonwoven fabric, which consists in particular of filaments of thermoplastic material. In principle, however, the device according to the invention can also be used for applying the fluid medium to other webs. In the context of the invention, fluid media are to be understood as meaning, in particular, liquid media, in particular finishing agents or softening agents, which are applied to the material web for adjusting or changing the properties of the material web. As already explained above, these may be wetting agents, in particular surfactants and their mixtures, which are preferably applied in the form of solutions or emulsions. Fluid medium then means such a solution or emulsion. In principle, however, other fluid or liquid media can be applied to the web.

Zweckmäßigerweise wird zum Aufbringen des fluiden Mediums die Unterseite der Warenbahn über die Oberseite der Auftragsfläche geführt. Das fluide Medium wird dabei in den Kontaktbereichen zwischen Warenbahn und Auftragsfläche aufgebracht, während es in den von den Abdeckelementen abgedeckten Bereichen der Auftragsfläche nicht aufgebracht wird. In den Kontaktbereichen findet zweckmäßigerweise ein kontinuierliches bzw. ununterbrochenes Aufbringen bzw. streifenförmiges Aufbringen des fluiden Mediums auf die Warenbahn statt. Es versteht sich, dass die Abdeckelemente undurchlässig oder im Wesentlichen undurchlässig für das fluide Medium sind. Beim Führen der Warenbahn über die Auftragsfläche befinden sich diese Abdeckelemente zwischen Auftragsfläche und Warenbahn, so dass ein Kontakt der Warenbahn mit dem fluiden Medium in diesen Bereichen nicht stattfinden kann.Conveniently, the bottom of the web is guided over the top of the application surface for applying the fluid medium. In this case, the fluid medium is applied in the contact regions between the material web and the application surface, while it is not applied in the regions of the application surface covered by the covering elements. In the contact areas, a continuous or continuous application or strip-like application of the fluid medium to the web takes place expediently. It is understood that the cover members are impermeable or substantially impermeable to the fluid medium. When guiding the material web over the application surface, these covering elements are located between the application surface and the material web, so that contact of the material web with the fluid medium in these regions can not take place.

Dass die Abdeckelemente unmittelbar benachbart positioniert werden meint insbesondere, dass kein Spalt bzw. keine Lücke zwischen den benachbarten Abdeckelementen ausgebildet ist oder dass lediglich ein minimaler Spalt zwischen den benachbarten Abdeckelementen vorhanden ist. Minimaler Spalt bezieht sich dabei auf einen Abstand von weniger als 2 mm, vorzugsweise von weniger als 1 mm und bevorzugt von weniger als 0,5 mm zwischen den beiden benachbarten Abdeckelementen. - Bei der überlappenden Anordnung der Abdeckelemente sind die beteiligten Abdeckelemente zweckmäßigerweise bereichsweise übereinander angeordnet.The fact that the cover elements are positioned immediately adjacent means, in particular, that no gap or no gap is formed between the adjacent cover elements or that only a minimal gap exists between the adjacent cover elements. Minimum gap refers to a distance of less than 2 mm, preferably less than 1 mm and preferably less than 0.5 mm between the two adjacent cover elements. - In the overlapping arrangement of the cover elements, the cover elements involved are expediently arranged in sections one above the other.

Nach besonders bevorzugter Ausführungsform der Erfindung ist die Auftragsfläche die Oberfläche einer Auftragswalze, die zweckmäßigerweise zylinderförmig ausgebildet ist. Es liegt dabei im Rahmen der Erfindung, dass die Auftragswalze rotiert und dass die Walze bevorzugt bereichsweise in einen Behälter mit dem fluiden bzw. flüssigen Medium eintaucht. Auf diese Weise kann die Auftragswalze kontinuierlich mit dem auf die Warenbahn aufzubringenden fluiden Medium versorgt werden. Es liegt weiterhin im Rahmen der Erfindung, dass die Warenbahn quer bzw. senkrecht zur Längsachse der Auftragswalze über die Auftragswalze befördert bzw. bewegt wird.According to a particularly preferred embodiment of the invention, the application surface is the surface of an applicator roll, which is expediently cylindrical. It is within the scope of the invention that the application roller rotates and that the roller preferably immersed in some areas in a container with the fluid or liquid medium. In this way, the application roller can be supplied continuously with the applied to the web fluid medium. It is also within the scope of the invention that the web is conveyed transversely or perpendicular to the longitudinal axis of the applicator roll on the applicator roll or moved.

Es wurde bereits oben darauf hingewiesen, dass die sehr bevorzugte Ausführungsform der Erfindung eine Vorrichtung betrifft, mit der ein streifenförmiger Auftrag bzw. ein Streifenauftrag des fluiden Mediums auf die Warenbahn stattfindet. Dabei wird die Warenbahn lediglich in streifenförmigen Bereichen mit dem fluiden Medium bzw. mit der Avivage befeuchtet und die Eigenschaften der Warenbahn werden nur in diesen streifenförmigen Bereichen entsprechend der Wirkung des fluiden Mediums beeinflusst bzw. verändert. Bei dieser bevorzugten Ausführungsform sind die Abdeckelemente als Abdeckstreifen ausgebildet. Zweckmäßigerweise ist die Längserstreckung dieser Abdeckstreifen quer bzw. senkrecht zur Längsachse der Auftragswalze orientiert. Mit den Abdeckstreifen werden streifenförmige Abdeckbereiche abgedeckt, in denen kein Kontakt der Auftragsfläche bzw. Auftragswalze mit der Warenbahn stattfindet und in denen folglich das fluide Medium bzw. die Avivage die Warenbahn nicht beeinflusst bzw. verändert.It has already been pointed out above that the very preferred embodiment of the invention relates to a device with which a strip-like application or a strip application of the fluid medium takes place on the material web. The web is moistened only in strip-shaped areas with the fluid medium or with the lubricant and the properties of the web are affected or changed only in these strip-shaped areas according to the effect of the fluid medium. In this preferred embodiment, the cover elements are designed as cover strips. Conveniently, the longitudinal extension of these cover strips is oriented transversely or perpendicular to the longitudinal axis of the applicator roll. With the cover strips strip-shaped covering areas are covered, in which no contact of the application surface or applicator roll with the web takes place and in which consequently the fluid medium or the lubricant does not affect or change the web.

Es liegt im Rahmen der Erfindung, dass die Abdeckstreifen verschiebbar sind und zwar sind sie bei der bevorzugt vorgesehenen Auftragswalze zweckmäßigerweise in Richtung der Längsachse dieser Auftragswalze verschiebbar. Erfindungsgemäß sind die zumindest teilweise mit Abdeckstreifen verbundenen Anschlusselemente für die Verschiebung der Abdeckstreifen in besonderer Weise orientiert bzw. angeordnet. Es liegt im Rahmen der Erfindung, dass zumindest ein Teil der Anschlusselemente in der Verstelleinrichtung mit der Maßgabe versetzt zueinander angeordnet sind, dass beim Verschieben dieser versetzt angeordneten Anschlusselemente zumindest ein Teil dieser Anschlusselemente über zumindest einen Teil ihres Verschiebeweges kollisionsfrei aneinander vorbei verschiebbar bzw. bewegbar sind. Bei der bevorzugten Ausführungsform mit der Auftragswalze sind die Anschlusselemente in Richtung der Längsachse der Auftragswalze verschiebbar. Wenn zwei dieser Anschlusselemente kollisionsfrei aneinander vorbeibewegt werden und wenn an beide Anschlusselemente Abdeckstreifen angeschlossen sind, findet eine Überlappung dieser Abdeckelemente bzw. Abdeckstreifen statt. Bei dieser kollisionsfreien Verschiebung von Anschlusselementen können an die Anschlusselemente angeschlossene Abdeckelemente bzw. Abdeckstreifen also gleichsam übereinander geschoben werden.It is within the scope of the invention that the cover strips are displaceable and that they are expediently displaceable in the direction of the longitudinal axis of this application roller in the case of the preferably provided applicator roller. According to the invention, the connection elements connected at least partially with cover strips are oriented or arranged in a special way for the displacement of the cover strips. It is within the scope of the invention that at least a portion of the connection elements in the adjustment are offset from each other with the proviso that at least a portion of these connection elements on at least part of their displacement path are collapsible past each other and movable during displacement of these staggered connection elements , In the preferred embodiment with the applicator roll, the connecting elements are displaceable in the direction of the longitudinal axis of the applicator roll. If two of these connection elements are moved past each other without collision and if cover strips are connected to both connection elements, an overlapping of these covering elements or covering strips takes place. In this collision-free displacement of connecting elements connected to the connection elements cover elements or cover strips can therefore be pushed so to speak one above the other.

Es liegt im Rahmen der Erfindung, dass die Verstelleinrichtung unabhängig voneinander verstellbare lineare Verstelleinheiten bzw. Verstellstangen aufweist, dass an jede Verstellstange zumindest ein Anschlusselement angeschlossen ist und dass durch Betätigung bzw. Verstellung einer Verstellstange das daran angeschlossene Anschlusselement verschiebbar ist. Wenn an dieses Anschlusselement ein Abdeckelement bzw. ein Abdeckstreifen angeschlossen ist, wird mit der Verschiebung des Anschlusselementes auch das Abdeckelement bzw. der Abdeckstreifen über der Auftragsfläche/Auftragswalze verschoben. Gemäß bevorzugter Ausführungsform der Erfindung ist an eine Verstellstange lediglich ein Anschlusselement angeschlossen. Die Verstellstangen sind zweckmäßigerweise parallel zueinander und vorzugsweise parallel zur Längsachse der Auftragswalze orientiert. Nach bevorzugter Ausführungsvariante ist eine Mehrzahl von Verstellstangen in einer Ebene, bevorzugt in einer horizontalen Ebene angeordnet. Es liegt im Rahmen der Erfindung, dass die Verstellstangen als Verstellspindeln ausgeführt sind. Zweckmäßigerweise ist eine Verstellspindel mit einem Außengewinde versehen und das an diese Verstellspindel angeschlossene Anschlusselement weist ein entsprechendes Innengewinde auf. Durch Rotation der Verstellspindel wird dann das Anschlusselement auf der zugeordneten Verstellspindel in Längsrichtung der Verstellspindel verschoben. Die Betätigung der Verstellstangen/Verstellspindeln kann manuell oder automatisch erfolgen. Mit der beschriebenen Ausführungsform ist eine sehr präzise Führung der Anschlusselemente und somit auch eine sehr exakte Bewegung der Abdeckelemente gewährleistet. - Grundsätzlich sind auch andere Ausbildungen der erfindungsgemäßen Verstelleinrichtung denkbar. So könnten beispielsweise mehrere Verstellstangen vorgesehen sein, an denen die Anschlusselemente klemmend befestigt sind.It is within the scope of the invention that the adjusting device has independently adjustable linear adjusting units or adjusting rods, that at least one connecting element is connected to each adjusting rod and that the connecting element connected thereto is displaceable by actuation or adjustment of an adjusting rod. If at this Connection element is a cover or a cover strip is connected, is moved with the displacement of the connecting element and the cover or the cover strip over the application surface / applicator roll. According to a preferred embodiment of the invention, only one connecting element is connected to an adjusting rod. The adjusting rods are expediently oriented parallel to one another and preferably parallel to the longitudinal axis of the applicator roll. According to a preferred embodiment, a plurality of adjusting rods in a plane, preferably arranged in a horizontal plane. It is within the scope of the invention that the adjusting rods are designed as adjusting spindles. Conveniently, an adjusting spindle is provided with an external thread and connected to this adjustment connecting element has a corresponding internal thread. By rotation of the adjusting spindle, the connecting element is then displaced on the associated adjusting spindle in the longitudinal direction of the adjusting spindle. The actuation of the adjusting rods / adjusting spindles can be done manually or automatically. With the described embodiment, a very precise guidance of the connection elements and thus also a very precise movement of the cover is ensured. - In principle, other embodiments of the adjusting device according to the invention are conceivable. For example, a plurality of adjusting rods could be provided, to which the connecting elements are fastened by clamping.

Nach einer sehr bevorzugten Ausführungsform der Erfindung sind Gruppen von Verstellstangen vorgesehen und dabei ist jede Gruppe von Verstellstangen zumindest einem Teilbereich der Auftragsfläche zugeordnet. Nach dieser Ausführungsform ist also eine Mehrzahl von Gruppen vorgesehen, wobei jeder Gruppe eine Mehrzahl von Verstellstangen zugeordnet ist. Jede Gruppe von Verstellstangen mit den an den Verstellstangen jeweils angeschlossenen Anschlusselementen und daran ggf. wiederum angeschlossenen Abdeckelementen ist für die Abdeckung in zumindest einem Teilbereich der Auftragsfläche/Auftragswalze vorgesehen. Die Anschlusselemente mit den daran ggf. angeschlossenen Abdeckelementen sind vorzugsweise nur in diesem Teilbereich verschiebbar. Mit anderen Worten ist dann den einzelnen Anschlusselementen jeweils nur ein begrenzter Verschiebeweg zugeordnet. Bei der bevorzugt eingesetzten Auftragswalze ist die Auftragswalze bei dieser Ausführungsform zweckmäßigerweise bezüglich ihrer Längsrichtung in mehrere Teilbereiche aufgeteilt, die bevorzugt gleich lang sind. Gemäß bevorzugter Ausführungsvariante ist jede Gruppe von Verstellstangen in einer Ebene bzw. in einer horizontalen Ebene angeordnet. Die mehreren Gruppen von Verstellstangen sind dann zweckmäßigerweise in übereinander angeordneten zueinander parallelen Ebenen bzw. zueinander parallelen horizontalen Ebenen angeordnet. Somit ergibt sich gleichsam eine Matrix von Verstellstangen/Verstellspindeln.According to a very preferred embodiment of the invention, groups of adjusting rods are provided, and each group of adjusting rods is associated with at least one subregion of the application surface. According to this embodiment, therefore, a plurality of groups is provided, wherein each group is associated with a plurality of adjustment rods. Each group of adjusting rods with the connection elements respectively connected to the adjusting rods and possibly in turn connected cover elements is intended for the cover in at least a portion of the application surface / applicator roll. The connecting elements with the cover elements optionally connected thereto are preferably displaceable only in this subregion. In other words, the individual connection elements are assigned only a limited displacement path. In the case of the application roller which is preferably used, the application roller in this embodiment is expediently divided with regard to its longitudinal direction into a plurality of partial regions which are preferably of equal length. According to a preferred embodiment variant, each group of adjusting rods is arranged in one plane or in one horizontal plane. The plurality of groups of adjusting rods are then expediently arranged in superposed parallel planes or parallel horizontal planes. This results in a matrix of adjusting rods / adjusting spindles.

Es liegt im Rahmen der Erfindung, dass lediglich an einen Teil der Anschlusselemente Abdeckelemente angeschlossen sind. Mit anderen Worten sind gemäß dieser Ausführungsform mehr Anschlusselemente vorhanden als im Betrieb der Vorrichtung eingesetzte Abdeckelemente/Abdeckstreifen. Auf diese Weise ergeben sich vielfältige Variationsmöglichkeiten und es ist vor allem eine gezielte Abdeckung kleinerer Bereiche der Auftragsfläche/Auftragswalze möglich. Eine sehr bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass die Abdeckelemente bei Bedarf von den Anschlusselementen entfernbar bzw. entkoppelbar sind und/oder dass die Abdeckelemente an freie Anschlusselemente anschließbar sind. Die Abdeckelemente können dabei von ihren zugeordneten Anschlusselementen entfernt werden und dann an andere freie Anschlusselemente angeschlossen werden. Natürlich können bei Bedarf auch zusätzliche Abdeckelemente an Anschlusselemente angeschlossen werden.It is within the scope of the invention that cover elements are connected only to a part of the connection elements. In other words, according to this embodiment, more connection elements are present than cover elements / cover strips used during operation of the device. In this way, there are many possible variations and it is above all a targeted coverage of smaller areas of the application surface / applicator roll possible. A very preferred embodiment of the invention is characterized in that the cover elements can be removed or decoupled from the connection elements as required and / or that the cover elements can be connected to free connection elements. The cover elements can be removed from their associated connection elements and then connected to other free connection elements. Of course, if necessary, additional cover elements can be connected to connection elements.

Gemäß einer besonders bevorzugten Ausführungsform der Erfindung sind die Abdeckelemente/Abdeckstreifen jeweils lediglich mit einem Ende an die Verstelleinrichtung bzw. an Anschlusselemente der Verstelleinrichtung angeschlossen. Mit anderen Worten haben die Abdeckelemente/Abdeckstreifen bei dieser Ausführungsform ein freies Ende und liegen diesbezüglich gleichsam lose auf der Auftragsfläche bzw. Auftragswalze auf. Grundsätzlich könnten die Abdeckelemente/Abdeckstreifen aber auch mit beiden Enden an die Verstelleinrichtung bzw. an Anschlusselemente der Verstelleinrichtung angeschlossen sein.According to a particularly preferred embodiment of the invention, the cover / cover strips are each connected at one end to the adjustment or to connection elements of the adjustment. In other words, the cover / cover strip in this embodiment, a free end and are in this regard as it were loose on the application surface or applicator roll. In principle, however, the cover elements / cover strips could also be connected with both ends to the adjusting device or to connecting elements of the adjusting device.

Die Abdeckelemente/Abdeckstreifen bestehen vorzugsweise aus Kunststoff, bevorzugt aus faserverstärktem bzw. glasfaserverstärktem Kunststoff und sehr bevorzugt aus teflonbeschichtetem faserverstärktem/glasfaserverstärktem Kunststoff. Grundsätzlich könnten die Abdeckelemente/Abdeckstreifen aber auch beispielsweise aus Blech bestehen.The cover elements / cover strips are preferably made of plastic, preferably of fiber-reinforced or glass-fiber reinforced plastic and very preferably of Teflon-coated fiber-reinforced / glass-fiber reinforced plastic. In principle, the cover / cover strip but could also be made of sheet metal, for example.

Der Erfindung liegt die Erkenntnis zugrunde, dass mit der erfindungsgemäßen Vorrichtung eine sehr flexible und variable Einstellung von Abdeckbereichen an einer Warenbahn möglich ist. Insbesondere kann die Breite eines Abdeckbereiches im Gegensatz zu den aus dem Stand der Technik bekannten Maßnahmen auf einfache Weise und großen Aufwand verwirklicht werden. Das wird erfindungsgemäß dadurch möglich, dass die Abdeckelemente bzw. Abdeckstreifen mit der erfindungsgemäßen Verstelleinrichtung insbesondere überlappend oder auch unmittelbar benachbart angeordnet werden können. Durch die erfindungsgemäß ermöglichte einfache Einstellung des Überlappungsausmaßes kann die Breite der Abdeckbereiche kontinuierlich und präzise eingestellt werden. In der erfindungsgemäßen Verstelleinrichtung ist eine sehr exakte Führung der Anschlusselemente und der daran angeschlossenen Abdeckelemente gewährleistet. Mit der erfindungsgemäßen Vorrichtung ist eine gezielte unabhängige Einstellung der Positionen und Breiten der Abdeckbereiche möglich und zwar auch während des Betriebs der Vorrichtung. Unerwünschte Unterbrechungen und Umbauzeiten müssen dabei also nicht in Kauf genommen werden. Im Übrigen kann durch die variable und präzise Einstellung der Abdeckbereiche der negative Einfluss weiterer Bearbeitungsschritte auf die Position und Breite der Abdeckbereiche auf der Warenbahn kompensiert werden. Hervorzuheben ist weiterhin, dass die erfindungsgemäße Vorrichtung auf einfache und kostengünstige Weise herstellbar ist. Von besonderer Bedeutung ist dabei, dass auch bestehende Anlagen - beispielsweise zur Herstellung von Vliesstoffen - mit der erfindungsgemäßen Vorrichtung ohne Probleme und ohne großen Aufwand nachgerüstet werden können.The invention is based on the finding that with the device according to the invention a very flexible and variable adjustment of coverage areas on a web is possible. In particular, the width of a covering area, in contrast to the measures known from the prior art can be realized in a simple manner and great effort. This is possible according to the invention in that the cover elements or cover strips can be arranged in particular overlapping or also directly adjacent to the adjusting device according to the invention. As a result of the simple adjustment of the overlap amount which is made possible according to the invention, the width of the cover areas can be set continuously and precisely. In the adjusting device according to the invention a very precise guidance of the connection elements and the cover elements connected thereto is ensured. With the device according to the invention is a targeted independent adjustment of the positions and Widths of the Abdeckbereiche possible, even during operation of the device. Unwanted interruptions and conversion times do not have to be accepted. Incidentally, the negative influence of further processing steps on the position and width of the covering regions on the material web can be compensated for by the variable and precise adjustment of the covering regions. It should also be emphasized that the device according to the invention can be produced in a simple and cost-effective manner. Of particular importance is that even existing equipment - for example, for the production of nonwovens - can be retrofitted with the device according to the invention without any problems and without much effort.

Die Figuren zeigen eine erfindungsgemäße Vorrichtung zur Aufbringung von fluiden Medien bzw. von Avivagen auf eine Warenbahn, die vorzugsweise und im Ausführungsbeispiel eine Vliesbahn 1 ist. Die Vliesbahn 1 wird über eine Auftragsfläche der Vorrichtung geführt, die im Ausführungsbeispiel von der Oberfläche einer Auftragswalze 2 gebildet wird. Die Bewegung der Vliesbahn 1 über die Auftragswalze 2 ist in Fig. 1 mit einem Pfeil angedeutet worden. Die Auftragswalze 2 ist zylinderförmig ausgebildet und rotiert im Betrieb der Vorrichtung. Dabei taucht die Auftragswalze 2 zweckmäßigerweise mit ihrem unteren Bereich in einen in den Figuren nicht dargestellten Behälter mit dem fluiden Medium ein. Auf diese Weise wird die Auftragswalze 2 gleichsam kontinuierlich mit dem fluiden Medium versorgt und das fluide Medium kann aufgrund der Rotation der Auftragswalze 2 auf die über die Auftragswalze 2 geführte Vliesbahn 1 aufgebracht werden. Die Aufbringung des fluiden Mediums erfolgt in den Kontaktbereichen 3, in denen die Unterseite der Vliesbahn 1 Kontakt mit der Auftragswalze 2 hat.The figures show a device according to the invention for the application of fluid media or of lubricant to a web, which is preferably and in the embodiment, a nonwoven web 1. The nonwoven web 1 is guided over an application surface of the device, which is formed in the embodiment of the surface of an applicator roll 2. The movement of the nonwoven web 1 over the applicator roll 2 is in Fig. 1 indicated by an arrow. The application roller 2 is cylindrical and rotates during operation of the device. In this case, the application roller 2 expediently with its lower portion in a container, not shown in the figures with the fluid medium. In this way, the application roller 2 is supplied as it were continuously with the fluid medium and the fluid medium can be applied due to the rotation of the applicator roller 2 on the guided over the applicator roller 2 nonwoven web 1. The application of the fluid medium takes place in the contact regions 3, in which the underside of the nonwoven web 1 has contact with the applicator roll 2.

Die erfindungsgemäße Vorrichtung ist mit einer Mehrzahl von als Abdeckstreifen 4 ausgebildeten Abdeckelementen ausgestattet. In den Fig. 1 und 4 wurden der Einfachheit halber lediglich zwei Abdeckstreifen 4 dargestellt. Grundsätzlich können an die erfindungsgemäße Vorrichtung aber auch mehr Abdeckstreifen 4 angeschlossen sein (siehe beispielsweise Fig. 5). Die Abdeckstreifen 4 decken Abdeckbereiche auf der Auftragswalze 2 ab, so dass in diesen Abdeckbereichen kein Kontakt zwischen Vliesbahn 1 und Auftragswalze 2 stattfindet. Auf diese Weise wird auf streifenförmigen Bereichen der Vliesbahn 1 kein fluides Medium aufgebracht. Andererseits wird in den streifenförmigen Kontaktbereichen 3 zwischen den Abdeckstreifen 4 fluides Medium auf die Vliesbahn 1 aufgebracht. Es findet also ein so genannter Streifenauftrag des fluiden Mediums bzw. der Avivage auf die Vliesbahn 1 statt.The device according to the invention is equipped with a plurality of covering elements 4 designed as cover strips. In the Fig. 1 and 4 For the sake of simplicity, only two cover strips 4 have been shown. In principle, however, more cover strips 4 can also be connected to the device according to the invention (see, for example, FIG Fig. 5 ). The cover strips 4 cover coverage areas on the applicator roll 2, so that no contact between nonwoven web 1 and applicator roll 2 takes place in these coverage areas. In this way, no fluid medium is applied to strip-shaped areas of the nonwoven web 1. On the other hand, fluid medium is applied to the nonwoven web 1 in the strip-shaped contact regions 3 between the cover strips 4. So there is a so-called strip application of the fluid medium or the lubricant on the nonwoven web 1 instead.

Die Abdeckstreifen 4 sind auf der Auftragswalze 2 bzw. relativ zur Auftragswalze 2 in Richtung der Längsachse der Auftragswalze 2 verschiebbar, und zwar in beiden Richtungen. Das wurde in Fig. 1 durch einen entsprechenden Doppelpfeil angedeutet. Es ist eine Verstelleinrichtung 5 mit einem Einrichtungsgehäuse 6 vorgesehen. In dem Einrichtungsgehäuse 6 der Verstelleinrichtung 5 wird eine Mehrzahl von Anschlusselementen 7 geführt. An jedes dieser Anschlusselemente 7 ist grundsätzlich ein Abdeckstreifen 4 anschließbar. Normalerweise wird aber lediglich an einen Teil der Anschlusselemente 7 jeweils ein Abdeckstreifen 4 angeschlossen. Die Anschlusselemente 7 sind in Richtung der Längsachse der Auftragswalze 2 verschiebbar, so dass auch die daran angeschlossenen Abdeckstreifen 4 entsprechend in Richtung der Längsachse der Auftragswalze 2 verschiebbar sind. Anschlusselemente 7 sind in der Verstelleinrichtung 5 mit der Maßgabe versetzt zueinander angeordnet, dass insbesondere benachbarte versetzt zueinander angeordnete Anschlusselemente 7 über einen Teil ihres Verschiebeweges kollisionsfrei aneinander vorbei verschiebbar sind. Die Anschlusselemente 7 sind im Ausführungsbeispiel in Führungsschlitzen 8 des Einrichtungsgehäuses 6 geführt (Fig. 2). Es ist erkennbar, dass die Führungsschlitze 8 bzw. Verschiebungswege von benachbarten versetzt zueinander angeordneten Anschlusselementen 7 sich teilweise überlappen, so dass die Anschlusselemente 7 hier kollisionsfrei aneinander vorbeiführbar sind. Wenn an zwei solche benachbarte Anschlusselemente 7, deren Verschiebewege bzw. Führungsschlitze 8 sich gleichsam überlappen, Abdeckstreifen 4 angeschlossen sind, kann eine Überlappung dieser Abdeckstreifen 4 auf der Auftragswalze 2 verwirklicht werden. Dabei kann das Überlappungsmaß dieser Abdeckstreifen 4 variabel und kontinuierlich durch Verschiebung der Anschlusselemente 7 eingestellt werden. Es ist auch möglich, dass zwei oder mehr Abdeckstreifen 4 unmittelbar benachbart zueinander angeordnet werden bzw. in Richtung der Längsachse der Auftragswalze 2 unmittelbar aneinander anschließen. Diese vorgenannten Verstellmöglichkeiten für die Abdeckstreifen 4 sind insbesondere in den Fig. 5b und 5c dargestellt worden.The cover strips 4 are displaceable on the applicator roller 2 or relative to the applicator roller 2 in the direction of the longitudinal axis of the applicator roller 2, in both directions. That was in Fig. 1 indicated by a corresponding double arrow. There is provided an adjusting device 5 with a device housing 6. In the device housing 6 of the adjusting device 5, a plurality of connecting elements 7 is guided. At each of these connection elements 7 is basically a cover strip 4 can be connected. Normally, however, only one cover strip 4 is connected to only one part of the connection elements 7. The connection elements 7 are displaceable in the direction of the longitudinal axis of the application roller 2, so that the cover strips 4 connected thereto are correspondingly displaceable in the direction of the longitudinal axis of the application roller 2. Connecting elements 7 are offset in the adjusting device 5 with the proviso arranged to each other, that in particular adjacent offset from each other arranged connection elements 7 are collision-free past each other over a part of their displacement path. The connection elements 7 are guided in the exemplary embodiment in guide slots 8 of the device housing 6 ( Fig. 2 ). It can be seen that the guide slots 8 or displacement paths of adjacent mutually offset connection elements 7 partially overlap, so that the connection elements 7 can be guided past each other in a collision-free manner. If at two such adjacent connection elements 7, the displacement paths or guide slots 8 overlap, as it were, cover strips 4 are connected, an overlap of these cover strips 4 can be realized on the applicator roll 2. In this case, the overlapping dimension of these cover strips 4 can be adjusted variably and continuously by displacement of the connection elements 7. It is also possible that two or more cover strips 4 are arranged directly adjacent to each other or in the direction of the longitudinal axis of the applicator roll 2 directly to each other connect. These aforementioned adjustment possibilities for the cover strips 4 are in particular in the Fig. 5b and 5c been presented.

Vorzugsweise und im Ausführungsbeispiel weist die Verstelleinrichtung 5 unabhängig voneinander verstellbare Verstellspindeln 9 auf. Im Ausführungsbeispiel ist an jede Verstellspindel 9 ein Anschlusselement 7 angeschlossen. Die Verstellspindeln 9 weisen im Ausführungsbeispiel ein nicht näher dargestelltes Außengewinde auf und die Anschlusselemente 7 sind jeweils mit einem Anschlussflansch 10 ausgerüstet, der von der jeweils zugeordneten Verstellspindel 9 durchfasst wird. Der Anschlussflansch 10 hat dabei ein entsprechendes Innengewinde. Durch Rotation einer Verstellspindel 9 kann somit das an diese Verstellspindel 9 angeschlossene Anschlusselement 7 in Richtung der Längsachse der Auftragswalze 2 bewegt bzw. verschoben werden. Ein an ein Anschlusselement 7 angeschlossener Abdeckstreifen 4 wird dann entsprechend in Längsrichtung der Auftragswalze 2 verschoben. Im Ausführungsbeispiel sind die Verstellspindeln 9 im Übrigen parallel zueinander und parallel zur Längsachse der Auftragswalze 2 angeordnet.Preferably, and in the embodiment, the adjusting device 5 independently adjustable adjusting spindles 9. In the exemplary embodiment, a connecting element 7 is connected to each adjusting spindle 9. The adjusting spindles 9 have in the exemplary embodiment on an unspecified external thread and the connecting elements 7 are each equipped with a flange 10, which is encompassed by the respective associated adjusting spindle 9. The connection flange 10 has a corresponding internal thread. By rotation of an adjusting spindle 9, the connecting element 7 connected to this adjusting spindle 9 can thus be moved or displaced in the direction of the longitudinal axis of the application roller 2. A connected to a connection element 7 cover strip 4 is then moved accordingly in the longitudinal direction of the applicator roll 2. In the exemplary embodiment, the adjusting spindles 9 are otherwise arranged parallel to one another and parallel to the longitudinal axis of the application roller 2.

Im Ausführungsbeispiel sind drei Gruppen 11, 12, 13 von Verstellspindeln 9 vorgesehen, wobei den Gruppen 11, 12, 13 bzw. den daran angeschlossenen Anschlusselementen 7 Teilbereiche der Auftragswalze 2 zugeordnet sind. Jede Gruppe 11, 12, 13 von Verstellspindeln 9 mit daran angeschlossenen Anschlusselementen 7 und daran ggf. angeschlossenen Abdeckstreifen 4 ist also lediglich für Abdeckungen in einem Teilbereich der Auftragswalze 2 vorgesehen. So ist beispielsweise die untere Gruppe 13 von Verstellspindeln 9 (siehe insbesondere Fig. 3) für Abdeckungen im äußeren linken Teilbereich 14 der Auftragswalze 2 zuständig. An die Verstellspindel 9a ist das Anschlusselement 7a angeschlossen und durch Betätigung der Verstellspindel 9a ist das Anschlusselement 7a innerhalb des zugeordneten Führungsschlitzes 8 verschiebbar. Dementsprechend ist an die Verstellspindel 9b der unteren Gruppe 13 das Anschlusselement 7b angeschlossen und bei Betätigung dieser Verstellspindel 9b in dem zugeordneten Führungsschlitz 8 verschiebbar. In Fig. 2 ist erkennbar, dass die Führungsschlitze 8 der Anschlusselemente 7a und 7b teilweise überlappen. Somit können die Anschlusselemente 7a und 7b kollisionsfrei aneinander vorbeibewegt werden und dabei kann beispielsweise eine Überlappung von Abdeckstreifen 4 verwirklicht werden, die an diese Anschlusselemente 7a und 7b angeschlossen sind. Entsprechendes gilt auch für die Anschlusselemente 7c und 7d, die an die Verstellspindeln 9c und 9d der unteren Gruppe 13 von Verstellspindeln 9 angeschlossen sind. Im Ausführungsbeispiel sind die Verstellspindeln 9 jeder Gruppe 11, 12, 13 in einer Ebene bzw. in einer horizontalen Ebene angeordnet. Hier wird mit einer 3x4-Matrix von Verstellspindeln gearbeitet.In the embodiment, three groups 11, 12, 13 are provided by adjusting spindles 9, wherein the groups 11, 12, 13 and the connected thereto connecting elements 7 subregions of the applicator roll 2 are assigned. Each group 11, 12, 13 of adjusting spindles 9 with connecting elements 7 connected thereto and possibly attached covering strips 4 is thus provided only for covers in a partial region of the application roller 2. For example, the lower group 13 of adjusting spindles 9 (see in particular Fig. 3 ) Responsible for covers in the outer left portion 14 of the applicator roll 2. To the adjusting spindle 9a, the connecting element 7a is connected and by actuation of the adjusting spindle 9a, the connecting element 7a within the associated guide slot 8 is displaceable. Accordingly, the adjusting spindle 9b is the lower one Group 13, the connecting element 7b connected and displaceable in the associated guide slot 8 upon actuation of this adjusting spindle 9b. In Fig. 2 it can be seen that the guide slots 8 of the connecting elements 7a and 7b partially overlap. Thus, the connection elements 7a and 7b can be moved past each other without collision and, for example, an overlap of cover strips 4 can be realized, which are connected to these connection elements 7a and 7b. The same applies to the connecting elements 7c and 7d, which are connected to the adjusting spindles 9c and 9d of the lower group 13 of adjusting spindles 9. In the exemplary embodiment, the adjusting spindles 9 of each group 11, 12, 13 are arranged in one plane or in one horizontal plane. Here we work with a 3x4 matrix of adjusting spindles.

Bei Bedarf können an freie Anschlusselemente 7 zusätzliche Abdeckstreifen 4 angeschlossen werden oder es können Abdeckstreifen 4 von Anschlusselementen 7 entfernt bzw. entkoppelt werden und beispielsweise an andere Anschlusselemente 7 angeschlossen werden. - Vorzugsweise und im Ausführungsbeispiel sind die Abdeckstreifen 4 lediglich mit einem Ende an die Verstelleinrichtung 5 bzw. an die Anschlusselemente 7 der Verstelleinrichtung 5 angeschlossen. Mit anderen Worten weisen die Abdeckstreifen 4 ein freies Ende auf und liegen bezüglich dieses Endes quasi lose auf der Auftragswalze 2 auf.If required, additional cover strips 4 can be connected to free connection elements 7 or cover strips 4 can be removed or decoupled from connection elements 7 and, for example, connected to other connection elements 7. Preferably, and in the exemplary embodiment, the cover strips 4 are connected at one end only to the adjusting device 5 or to the connecting elements 7 of the adjusting device 5. In other words, the cover strips 4 have a free end and lie with respect to this end quasi loosely on the applicator roll 2.

In der Fig. 5 sind drei verschiedene Funktionsstellungen von vier an Anschlusselementen 7 angeschlossenen Abdeckstreifen 4 dargestellt. Im Funktionszustand gemäß Fig. 5a sind alle vier Abdeckstreifen 4 beabstandet voneinander angeordnet. Mit anderen Worten sind zwischen den Abdeckstreifen 4 jeweils Kontaktbereiche 3 vorgesehen, in denen das fluide Medium von der Auftragswalze 2 auf die Vliesbahn 1 aufbringbar ist. In der Funktionsstellung nach Fig. 5b sind alle vier Abdeckstreifen 4 unmittelbar nebeneinander angeordnet worden. Somit ergibt sich ein einziger relativ breiter Abdeckstreifen 4, dessen Breite sich aus der Summe der Breiten der vier Abdeckstreifen 4 ergibt. In der Funktionsstellung gemäß Fig. 4c sind jeweils zwei Abdeckstreifen 4 überlappend übereinander angeordnet worden. Das Überlappungsausmaß ist hier bei den beiden Paaren von Abdeckstreifen 4 unterschiedlich. Durch Einstellung des Überlappungsausmaßes kann die Breite des resultierenden Abdeckbereiches kontinuierlich und variabel eingestellt werden.In the Fig. 5 three different functional positions of four connected to connecting elements 7 cover strip 4 are shown. In the functional state according to Fig. 5a all four cover strips 4 are spaced from each other. In other words, contact areas 3 are respectively provided between the cover strips 4 in which the fluid medium can be applied to the nonwoven web 1 by the application roller 2. In the functional position to Fig. 5b all four cover strips 4 are arranged directly next to each other Service. This results in a single relatively wide cover strip 4, the width of which results from the sum of the widths of the four cover strips 4. In the functional position according to Fig. 4c each two cover strips 4 have been arranged overlapping one another. The amount of overlap is different here for the two pairs of cover strips 4. By adjusting the amount of overlap, the width of the resulting cover area can be set continuously and variably.
