Description

Die Erfindung betrifft einen Düsenstreifen für eine Textilbearbeitungsmaschine.The invention relates to a nozzle strip for a textile processing machine.

Zur Verfestigung von Fliesstoffen sind Textilbearbeitungsmaschinen bekannt, bei denen Wasser unter hohem Druck in sehr feinen dünnen Strahlen auf ein Wirrfasergelege ausgestoßen wird. Die Wasserstrahlen übernehmen hierbei die Funktion von Filznadeln und verschlingen die Fasern des Wirrfasergeleges miteinander zur Erzeugung eines festen Vliesstoffes.For the consolidation of nonwovens textile processing machines are known in which water is ejected under high pressure in very fine thin jets on a random fiber fabric. The water jets here take over the function of felting needles and devour the fibers of the random fiber fabric together to produce a solid nonwoven fabric.

Die Textilmaschine weist hierzu einen Düsenstreifen auf, der eine Vielzahl von Düsenöffnungen enthält, durch die das Wasser zu feinen, nadelartigen Wasserstrahlen geformt wird. Die Düsenöffnungen sind einer sehr hohen Belastung ausgesetzt, da das Wasser unter hohem Druck von mehreren hundert Bar stehen kann. Sie sind daher einem erheblichen Verschleiß unterworfen.The textile machine has for this purpose a nozzle strip, which contains a plurality of nozzle openings, through which the water is formed into fine, needle-like water jets. The nozzle openings are exposed to a very high load, since the water can stand under high pressure of several hundred bars. They are therefore subject to considerable wear.

Aus der WO 2006/063112 A1 ist ein Düsenstreifen bekannt, der ein Trägerelement mit zylindrischen oder konischen Bohrungen aufweist. Separat hiervon ist ein streifenförmiges Abdeckelement vorgesehen, das eine Vielzahl von Düsenöffnungen enthält. Jede Düsenöffnung ist in Gebrauchslage fluchtend mit einer Bohrung des Trägerelements angeordnet. Über die Düsenöffnungen im Abdeckelement wird unter Druck stehendes Wasser zugeführt und zu einem feinen Strahl geformt, der dann durch die Bohrungen im Trägerelement aus dem Düsenstreifen austritt.From the WO 2006/063112 A1 a nozzle strip is known which has a carrier element with cylindrical or conical bores. Separately, a strip-shaped cover member is provided which includes a plurality of nozzle openings. Each nozzle opening is arranged in the position of use in alignment with a bore of the carrier element. Via the nozzle openings in the cover, pressurized water is supplied and formed into a fine jet, which then exits through the holes in the support member from the nozzle strip.

Ferner beschreibt die US 7237308 B2 einen Düsenstreifen, bei dem ebenfalls ein Trägerelement und separat davon ein Positionierstreifen vorhanden sind. Auch hier sind im Trägerelement zylindrische Bohrungen vorhanden, die jeweils mit einer Düsenöffnung im Positionierstreifen fluchten. Der Positionierstreifen kann in mehrere Segmente unterteilt werden, so dass nicht ein einziger Positionierstreifen mit allen Düsenöffnungen, sondern mehrere Positionierstreifen vorgesehen sind, die jeweils einen Teil der Düsenöffnungen aufweisen.Furthermore, the describes US 7237308 B2 a nozzle strip, in which also a carrier element and separately therefrom a positioning strips are present. Here, too, cylindrical bores are present in the support element, each of which is aligned with a nozzle opening in the positioning strip. The positioning strip can be divided into several segments, so that not a single positioning strip with all the nozzle openings, but a plurality of positioning strips are provided, each having a portion of the nozzle openings.

Ausgehend hiervon kann es als Aufgabe der vorliegenden Erfindung angesehen werden, den bekannten Düsenstreifen zu verbessern.Based on this, it can be regarded as an object of the present invention to improve the known nozzle strip.

Diese Aufgabe wird durch einen Düsenstreifen mit den Merkmalen des Patentanspruches 1 gelöst.This object is achieved by a nozzle strip with the features of claim 1.

Der erfindungsgemäße Düsenstreifen weist ein Trägerelement auf, in das ein Fluidkanal mit einer Eingangs- und einer Ausgangsmündung eingebracht ist. In Gebrauchslage des Düsenstreifens ist über der Eingangsmündung des Fluidkanals eine Folie mit einer Vielzahl von Düsenöffnungen gelegt. Jede Düsenöffnung einer Folie weist eine Fluideintrittsöffnung, sowie eine Fluidaustrittsöffnung auf. In Gebrauchslage des Düsenstreifens sind daher alle Fluidaustrittsöffnungen der Düsenöffnungen der Folie einer Eingangsmündung eines gemeinsamen Fluidkanals zugeordnet. Beim Betrieb der Textilbearbeitungsmaschine wird unter Druck stehendes Fluid durch die Düsenöffnungen zu feinen Fluidstrahlen geformt. Diese treten an der Ausgangsmündung des Fluidkanals aus, ohne dass die Fluidstrahlen mit dem Fluidkanal bzw. dem Trägerelement in Kontakt gelangen. Nach dem Austritt der fein gebündelten Fluidstrahlen treffen diese auf das Wirrfasergelege um dieses zu verfestigen. Das verwendete Fluid kann sowohl gasförmig als auch flüssig sein. Vorzugsweise wird Wasser als Fluid verwendet.The nozzle strip according to the invention has a carrier element into which a fluid channel having an inlet and an outlet orifice is inserted. In the position of use of the nozzle strip, a film with a plurality of nozzle openings is placed over the entrance mouth of the fluid channel. Each nozzle opening of a film has a fluid inlet opening and a fluid outlet opening. In the operating position of the nozzle strip, all fluid outlet openings of the nozzle openings of the film are therefore assigned to an inlet opening of a common fluid channel. In operation of the textile processing machine, pressurized fluid is formed through the nozzle orifices into fine fluid jets. These exit at the outlet orifice of the fluid channel without the fluid jets coming into contact with the fluid channel or the carrier element. After the exit of the finely bundled fluid jets, these impinge on the fiberglass layer to solidify this. The fluid used can be both gaseous and liquid. Preferably, water is used as the fluid.

Da alle Düsenöffnungen einer Folie einem gemeinsamen Fluidkanal zugeordnet sind, ist die Montage der Folie am Trägerelement vereinfacht. Eine exakte Ausrichtung jeder einzelnen Düsenöffnung mit jeweils einer separaten Bohrung im Trägerelement entfällt. Neben der vereinfachten Montage hat der erfindungsgemäße Düsenstreifen auch den Vorteil, dass die Verwendung deutlich flexibler ist als bei bisher bekannten Düsenstreifen. Abhängig von der Textilmaschine beziehungsweise vom zu bearbeitenden Wirrfasergelege können unterschiedliche Folien am Trägerelement angeordnet werden. Beispielsweise kann der Abstand von benachbarten Düsenöffnungen und/oder deren Form oder Durchmesser auf den konkreten Anwendungsfall angepasst werden. Für mehrere Folientypen kann dasselbe Trägerelement verwendet werden. Die Düsenöffnungen der Folie sind alle im Bereich der Eingangsmündung des Fluidkanals angeordnet, so dass der Abstand und die Größe der Düsenöffnungen variiert werden kann ohne eine Veränderung am Trägerelement vornehmen zu müssen.Since all the nozzle openings of a film are assigned to a common fluid channel, the mounting of the film on the carrier element is simplified. An exact alignment of each individual nozzle opening, each with a separate bore in the support element is eliminated. In addition to the simplified assembly of nozzle strip according to the invention also has the advantage that the use is much more flexible than previously known nozzle strips. Depending on the textile machine or of the random fiber web to be processed, different films can be arranged on the carrier element. For example, the distance from adjacent nozzle openings and / or their shape or diameter can be adapted to the specific application. For several types of film, the same carrier element can be used. The nozzle openings of the film are all arranged in the region of the inlet opening of the fluid channel, so that the distance and the size of the nozzle openings can be varied without having to make a change to the carrier element.

Im Bereich der Eingangsmündung des Fluidkanals kann am Trägerelement eine sich in einer Ebene erstreckende Befestigungsfläche für die Folie vorgesehen sein. Diese Befestigungsfläche kann gegenüber einer Bezugsebene geneigt ausgerichtet sein. Die Bezugsebene erstreckt sich vorzugsweise rechtwinklig zur vorgesehenen Strömungsrichtung von einer Druckquelle zu den Düsenöffnungen durch den Fluidkanal. Entsprechend der Neigung der Befestigungsfläche verläuft auch die daran befestigte Folie geneigt zur Bezugsebene, sodass sich die Abstrahlrichtung der Düsenöffnungen entsprechend der Neigung ändert. Auf diese Weise kann die Abstrahlrichtung der Düsenöffnungen angepasst werden, ohne die Folie oder die Düsenöffnungen zu verändern.In the region of the inlet mouth of the fluid channel, a fastening surface extending in a plane for the film can be provided on the carrier element. This attachment surface may be aligned with respect to a reference plane inclined. The reference plane preferably extends at right angles to the intended flow direction from a pressure source to the nozzle openings through the fluid channel. According to the inclination of the attachment surface, the film attached thereto is also inclined to the reference plane, so that the emission direction of the nozzle openings changes according to the inclination. In this way, the emission direction of the nozzle openings can be adjusted without to change the foil or the nozzle openings.

Vorzugsweise ist die Eingangs- sowie die Ausgangsmündung des Fluidkanals in Erstreckungsrichtung des Düsenstreifens schlitzförmig ausgeführt. Dies vereinfacht die Herstellung des Trägerelements. Anstelle von mehreren Bohrungen, die im Stand der Technik jeweils einer Düsenöffnung der Folie zugeordnet ist, sind einem erfindungsgemäßen Fluidkanal mehrere Düsenöffnungen zugeordnet. Die Herstellung von wenigen schlitzartigen Ausnehmungen im Trägerelement ist im Vergleich zu vielen Bohrungen bedeutend kostengünstiger. Entlang eines schlitzförmigen Fluidkanals und seiner Eingangsmündung sind die Düsenöffnungen in der Folie bei einer bevorzugten Ausführungsform gleichmäßig beabstandet in einer Reihe angeordnet.Preferably, the inlet and the outlet mouth of the fluid channel is slit-shaped in the extension direction of the nozzle strip. This simplifies the production of the carrier element. Instead of a plurality of bores, which is assigned in the prior art in each case a nozzle opening of the film, a plurality of nozzle openings are associated with a fluid channel according to the invention. The production of a few slot-like recesses in the support element is significantly cheaper compared to many holes. Along a slit-shaped fluid channel and its mouth, the nozzle openings in the film in a preferred embodiment are arranged evenly spaced in a row.

Bei einer bevorzugten Ausführungsform weist der Düsenstreifen genau ein Trägerelement auf, an dem mehrere Folien befestigt sind. Jeder Folie kann dabei ein separater Fluidkanal des Trägerelements zugeordnet sein. Somit sind alle Düsenöffnungen einer Folie jeweils einem der Fluidkanäle des Trägerelements zugeordnet. Das sich in einer Längsrichtung erstreckende Trägerelement weist somit mehrere voneinander getrennte Fluidkanäle auf, wodurch die Steifigkeit des Trägerelements gegenüber einem Trägerelement mit einem in Längsrichtung durchgehenden Fluidkanal erhöht ist. Die Steifigkeit kann weiter dadurch verbessert werden, dass die schlitzförmigen Fluidkanäle schräg zur Längsrichtung in das Trägerelement eingebracht sind. Vorzugsweise verlaufen die Fluidkanäle und somit auch die am Trägerelement angeordneten Folien parallel zueinander. Es ist dabei möglich, dass benachbart am Trägerelement angeordnete Folien in ihrer Erstreckungsrichtung gesehen versetzt nebeneinander angeordnet sind. Die Folien sind somit nicht fluchtend hintereinander angeordnet. Dadurch ergibt sich die Möglichkeit, dass zwei unmittelbar benachbart am Trägerelement angeordnete Folien mit ihrem jeweiligen Endabschnitt überlappend angeordnet sind. An diesem Endabschnitt können Verbindungsmittel vorhanden sein, sodass die beiden Folien lösbar miteinander verbunden werden können.In a preferred embodiment, the nozzle strip has exactly one carrier element to which a plurality of films are attached. Each film can be assigned a separate fluid channel of the carrier element. Thus, all nozzle openings of a film are each assigned to one of the fluid channels of the carrier element. The carrier element extending in a longitudinal direction thus has a plurality of fluid channels which are separate from one another, as a result of which the rigidity of the carrier element with respect to a carrier element having a longitudinally continuous fluid channel is increased. The rigidity can be further improved by introducing the slot-shaped fluid channels obliquely to the longitudinal direction into the carrier element. The fluid channels and thus also the films arranged on the carrier element preferably run parallel to one another. It is possible that adjacent to the carrier element arranged foils are arranged offset viewed in their direction of extension next to each other. The slides are not aligned in a row. This results in the possibility that two foils arranged directly adjacent to the carrier element are arranged with their respective end section overlapping. At this end portion connecting means may be present, so that the two films can be releasably connected to each other.

Bei einer vorteilhaften Ausgestaltung des Düsenstreifens mündet die Eingangsmündung des Fluidkanals in einer Vertiefung des Trägerelements ein. Diese Vertiefung dient zum Einsetzen der Folie. Die eingesetzte Folie kann mit der Umrandung der Vertiefung an mehreren Stellen zur Anlage gelangen, wodurch die Relativposition der Folie gegenüber dem Trägerelement vorgegeben ist. Die Düsenöffnungen der in die Vertiefung eingesetzten Folie sind dann automatisch über der Eingangsmündung des Fludikanals positioniert. Dadurch ergibt sich eine vereinfachte Montage des Düsenstreifens. Zweckmäßiger Weise ist für jede Folie eine separate Vertiefung im Trägerelement vorgesehen. Die Vertiefungen können voneinander getrennt ausgeführt sein. Um zwei benachbart am Trägerelement angeordnete Folien direkt miteinander verbinden zu können, können die Vertiefungen zumindest abschnittsweise miteinander verbunden sein.In an advantageous embodiment of the nozzle strip, the inlet mouth of the fluid channel opens into a depression of the carrier element. This depression serves to insert the film. The inserted film can come to rest with the border of the depression at several points, whereby the relative position of the film is predetermined relative to the carrier element. The nozzle openings of the film inserted into the recess are then automatically positioned over the entrance mouth of the Fludikanals. This results in a simplified assembly of the nozzle strip. Appropriately, a separate recess in the support member is provided for each slide. The depressions can be made separate from each other. In order to connect two adjacent arranged on the carrier element films directly to each other, the recesses may be at least partially connected to each other.

Die Erfindung betrifft einen Düsenstreifen 10 mit einem sich in eine Längsrichtung 11 erstreckenden Trägerelement 12 und mehreren Folien 13. Die Länge des Trägerelements 12 in Längsrichtung 11 kann abhängig von der Textilmaschine, in der der Düsenstreifen 10 eingesetzt wird, variieren und bis zu mehreren Metern betragen. Das Trägerelement 12 weist beim Ausführungsbeispiel nach Figur 1 einen rechteckförmigen Querschnitt auf, der eine Fluidaustrittsseite 22, eine Fluideintrittsseite 14 und zwei schmale Flachseiten 28 umfasst. Die Breite B des Trägerelements kann 10mm bis ca. 30mm betragen und die Dicke D in etwa 1-4mm betragen.The invention relates to a nozzle strip 10 with a carrier element 12 extending in a longitudinal direction 11 and a plurality of films 13. The length of the carrier element 12 in the longitudinal direction 11 can vary depending on the textile machine in which the nozzle strip 10 is used and up to several meters , The support element 12 has in the embodiment according to FIG. 1 a rectangular cross-section, which comprises a fluid outlet side 22, a fluid inlet side 14 and two narrow flat sides 28. The width B of the support member may be 10mm to about 30mm and the thickness D be about 1-4mm.

Abhängig von der Länge des Trägerelements 12 und mithin des Düsenstreifens 10 sind diesem mehrere streifenförmige Folien 13 zugeordnet, die im Querschnitt ebenfalls rechteckförmig ausgeführt sind. Die Folien 13 haben beim Ausführungsbeispiel eine Länge von etwa 90-100 mm. Sie sind 0,1 - 0,2mm dick und etwa 1 - 5mm breit.Depending on the length of the carrier element 12 and thus of the nozzle strip 10, a plurality of strip-shaped films 13 are assigned to it, which likewise have a rectangular cross-section. The films 13 in the embodiment have a length of about 90-100 mm. They are 0.1-0.2mm thick and about 1-5mm wide.

Jede Folie 13 weist eine Vielzahl von Düsenöffnungen 15 auf. Die Düsenöffnungen 15 durchsetzen die Folien 13 vollständig und weisen eine Fluideintrittsöffnung 19 und eine Fluidaustrittsöffnung 17 auf (Figur 4). Sowohl die Fluideintrittsöffnung 19 als auch die Fluidaustrittsöffnung 17 sind kreisrund. Der Durchmesser der Düsenöffnung 15 entspricht vorzugsweise etwa der Dicke der Folie 13 und beträgt beispielsgemäß etwa 0,1 mm. Beim bevorzugten Ausführungsbeispiel sind die Düsenöffnungen 15 in Erstreckungsrichtung der Folie 13 gesehen in einer Reihe mit regelmäßigem Abstand A entlang einer Geraden angeordnet (Figur 3). Der Abstand A ist variabel und kann beispielsweise etwa 1 mm betragen. Die Folien 13 sind vorzugsweise aus Stahl, Hartmetall oder Keramik hergestellt. Bei der Verwendung einer metallischen Folie 13 kann diese beispielsweise durch ein spanabhebendes oder ein spanloses Verfahren hergestellt werden.Each film 13 has a plurality of nozzle openings 15. The nozzle openings 15 pass completely through the foils 13 and have a fluid inlet opening 19 and a fluid outlet opening 17 (FIG. FIG. 4 ). Both the fluid inlet opening 19 and the fluid outlet opening 17 are circular. The diameter of the nozzle opening 15 preferably corresponds approximately to the thickness of the film 13 and is for example about 0.1 mm. In the preferred embodiment, the nozzle openings 15 are arranged in the direction of extension of the film 13 in a row at a regular distance A along a straight line ( FIG. 3 ). The distance A is variable and may be, for example, about 1 mm. The films 13 are preferably made of steel, carbide or ceramic. When using a metallic foil 13, this can be prepared for example by a machining or a chipless process.

Bei einem abgewandelten, nicht dargestellten Ausführungsbeispiel können die Düsenöffnungen 15 auch in zwei oder mehr Reihen nebeneinander entlang paralleler Geraden angeordnet sein. Es ist dabei möglich, die Düsenöffnungen 15 matrixartig versetzt anzuordnen oder Düsenanordnungen 15 benachbarter Reihen gegeneinander zu versetzen.In a modified, not shown embodiment, the nozzle openings 15 may be arranged in two or more rows next to each other along parallel lines. It is possible to arrange the nozzle openings 15 in a matrix-like manner or to offset nozzle arrangements 15 of adjacent rows from one another.

In Gebrauchslage sind die Folien 13 am Trägerelement 12 befestigt. Entsprechend der Anzahl der Folien 13 sind beim bevorzugten Ausführungsbeispiel im Trägerelement 12 mehrere Fluidkanäle 20 vorhanden, die das Trägerelement 12 in einer Strömungsrichtung 21 vollständig durchsetzen. Auf seiner in Gebrauchslage des Düsenstreifens 10 in der Textilmaschine dem zu bearbeitenden Wirrfasergelege zugeordneten Fluidaustrittsseite 22 tritt der Fluidkanal 20 unter Bildung einer Ausgangsmündung 24 aus. Die Strömungsrichtung 21 entspricht der Fließrichtung des Fluids von einer einer Druckquelle der Textilmaschine zugeordneten Fluideintrittsöffnung 19 der Folie 13 über die Fluidaustrittsöffnung 17 der Folie 13 über eine Eingangsmündung 23 des Fluidkanals 20 zur Ausgangsmündung 24. Der Fluidkanal 20 ist schlitzförmig ausgestaltet. Bei dem in den Figuren 1-5 dargestellten Ausführungsbeispiel des Düsenstreifens 10 erstreckt sich der schlitzförmige Fluidkanal 20 unter dem Winkel α schräg zu Längsrichtung 11 des Trägerelements 12. Die Verlaufsrichtung des schlitzförmigen Fluidkanals 20 gibt die in Gebrauchslage am Trägerelement 12 angeordnete Erstreckungsrichtung 35 der Folie 13 vor.In the position of use, the films 13 are attached to the carrier element 12. In accordance with the number of foils 13, in the preferred exemplary embodiment, a plurality of fluid channels 20 are present in the carrier element 12, which pass completely through the carrier element 12 in a flow direction 21. On its in the position of use of the nozzle strip 10 in the textile machine to be processed Gewrfasergelege associated fluid outlet side 22 of the fluid passage 20 exits to form an outlet port 24. The direction of flow 21 corresponds to the direction of flow of the fluid from a fluid inlet opening 19 of the film 13, which is assigned to a pressure source of the textile machine, via the fluid outlet opening 17 of the film 13 via an inlet mouth 23 of the fluid channel 20 to the outlet orifice 24. The fluid channel 20 is slot-shaped. In the in the Figures 1-5 illustrated embodiment of the nozzle strip 10, the slot-shaped fluid channel 20 extends at an angle α obliquely to the longitudinal direction 11 of the support member 12. The course direction of the slot-shaped fluid channel 20 are in the use position on the support member 12 arranged extension direction 35 of the film 13 before.

Beispielsgemäß ist der Querschnitt des Fluidkanals 20 in Strömungsrichtung 21 konstant und entspricht der Form der Ausgangsmündung 24. Somit hat der Fluidkanal 20 die Gestalt eines Schlitzes. Der Fluidkanal 20 kann durch verschiedene im Stand der Technik bekannte Verfahren wie beispielsweise spanabhebende - oder spanlose Verfahren in das Trägerelement 12 eingebracht werden.According to the example, the cross section of the fluid channel 20 in the flow direction 21 is constant and corresponds to the shape the output port 24. Thus, the fluid channel 20 has the shape of a slot. The fluid channel 20 can be introduced into the carrier element 12 by various methods known in the art, such as, for example, cutting or non-cutting methods.

Auf der Fluideintrittsseite 14 des Trägerelements 12 sind zur Befestigung der Folien 13 nutförmige Vertiefungen 25 in das Trägerelement 12 eingebracht. Die Anzahl der Vertiefungen 25 entspricht der Anzahl der am Trägerelement 12 anzuordnenden Folien 13. Jeder Folie 13 ist ein Fluidkanal 20 zugeordnet. Die Vertiefung 25 wird durch den Boden 26 und eine Kontur gebildet. Dabei begrenzt die Kontur die Vertiefung 25 in ihrer seitlichen Ausdehnung und bestimmt somit im wesentlichen die Breite und die Länge der Vertiefung 25 während der Boden 26 die Vertiefung 25 in ihrer Tiefe begrenzt und somit die Höhe der Vertiefung 25 bestimmt. Der Boden 26 jeder Vertiefung 25 stellt eine Befestigungsfläche zum Anbringen der jeweiligen Folie 13 dar. Der Fluidkanal 20 beginnt mit seiner Eingangsmündung 23 im Boden 26 und endet an der Fluidaustrittsseite 22. In Gebrauchslage liegt die Folie 13 an ihrer Innenseite 16 flächig auf dem Boden 26 auf. Die Konturen der Vertiefung 25 entsprechen im Wesentlichen der Kontur der Folie 13, so dass das Positionieren der Düsenöffnungen 15 relativ zur Eingangsmündung 23 des Fluidkanals 20 sehr einfach möglich ist. Die Lage der Folie 13 ist durch die Vertiefung 25 eindeutig vorgegeben. Wie dies in den Figuren 2 und 3 zu erkennen ist weicht die Kontur der Folie 13 beim bevorzugten Ausführungsbeispiel lediglich an den abgerundeten Enden von der Kontur der zugeordneten Vertiefung 25 ab, wodurch in den Eckbereichen zwischen der Folie 13 und der Vertiefung 25 Lücken 27 entstehen, die das Einsetzen und Herausnehmen der Folie 13 aus der Vertiefung 25 vereinfachen. Die Breite beziehungsweise die Länge der Vertiefung 25 entsprechen unter Berücksichtigung der Toleranz der Breite beziehungsweise der Länge der Folie 13.On the fluid inlet side 14 of the carrier element 12 groove-shaped depressions 25 are introduced into the carrier element 12 for fastening the foils. The number of recesses 25 corresponds to the number of films 13 to be arranged on the carrier element 12. Each film 13 is assigned a fluid channel 20. The recess 25 is formed by the bottom 26 and a contour. The contour limits the recess 25 in its lateral extent and thus determined essentially the width and the length of the recess 25 while the bottom 26, the recess 25 is limited in depth and thus determines the height of the recess 25. The bottom 26 of each recess 25 is a mounting surface for attaching the respective film 13. The fluid channel 20 begins with its inlet mouth 23 in the bottom 26 and ends at the fluid outlet side 22. In the use position, the film 13 is on its inside 16 on the floor 26th on. The contours of the recess 25 substantially correspond to the contour of the film 13, so that the positioning of the nozzle openings 15 relative to the inlet mouth 23 of the fluid channel 20 is very easy. The position of the film 13 is clearly defined by the recess 25. Like this in the Figures 2 and 3 can be seen, the contour of the film 13 deviates in the preferred embodiment only at the rounded ends of the contour of the associated recess 25, whereby 25 gaps 27 are formed in the corner regions between the film 13 and the recess, the insertion and removal of the film 13th from the recess 25 simplify. The width or the length of the recess 25 correspond to below Considering the tolerance of the width or the length of the film 13th

Bei in die Vertiefung 25 eingesetzter Folie 13 fluchten die Düsenöffnungen 15 mit der Eingangsmündung 23 des Fluidkanals 20. Es ist somit möglich, verschiedene Folientypen in die Vertiefung 25 einzusetzen und unabhängig vom Abstand A der Düsenöffnungen 15 oder deren Größe oder Kontur sicherzustellen, dass ein Fluidstrahl, geformt durch eine Düsenöffnung 15 den Fluidkanal 20 bzw. dessen Wände oder Begrenzungen nicht berührt und somit in seiner unveränderten Form auf das zu verfestigende Wirrfasergelege trifft. Unabhängig vom verwendeten Folientyp kann mithin dasselbe Trägerelement 12 verwendet werden, was die Flexibilität des Düsenstreifens 10 deutlich vergrößert. Dazu ist es notwendig, dass der Querschnitt des Fluidkanals 20 so bemessen ist, dass ein, durch eine Düsenöffnung 15 geformter Fluidstrahl, den Fluidkanal 20 nicht berührt und somit in seiner Form unverändert aus dem Trägermaterial 12 austreten kann.When inserted into the recess 25 film 13, the nozzle openings 15 are aligned with the inlet mouth 23 of the fluid channel 20. It is thus possible to use different types of film in the recess 25 and regardless of the distance A of the nozzle openings 15 or their size or contour to ensure that a fluid jet Formed by a nozzle opening 15, the fluid channel 20 or its walls or boundaries not touched and thus meets in its unmodified form to be solidified Gewrfasergelege. Thus, regardless of the type of film used, the same carrier element 12 can be used, which significantly increases the flexibility of the nozzle strip 10. For this purpose, it is necessary for the cross section of the fluid channel 20 to be dimensioned such that a fluid jet formed by a nozzle opening 15 does not touch the fluid channel 20 and thus can emerge unchanged from the carrier material 12 in its shape.

Beim ersten Ausführungsbeispiel des Düsenstreifens 10 gemäß der Figuren 1-5 ist jede Folie 13 aus einem einzigen Material ohne Füge- oder Befestigungsstellen hergestellt und somit einstückig ausgeführt. Jeder Folie 13 ist eine vollständig umrandete Vertiefung 25 zugeordnet. Die Tiefe der Vertiefung 25 ist so gewählt, dass die Außenseite 18 der eingesetzten Folie 13 im Wesentlichen eben mit der die Vertiefungen 25 umgebenden Fläche der Fluideintrittsseite 14 des Trägerelements 12 verläuft.In the first embodiment of the nozzle strip 10 according to the Figures 1-5 Each film 13 is made of a single material without joining or fastening points and thus made in one piece. Each film 13 is associated with a fully edged recess 25. The depth of the recess 25 is selected so that the outer side 18 of the inserted film 13 is substantially planar with the surface of the fluid inlet side 14 of the carrier element 12 that surrounds the depressions 25.

Wie dies gemäß der Figuren 3 und 4 veranschaulicht ist, kann zwischen der Folie 13 und dem Boden 26 der Vertiefung 25 eine Dichtungsschicht 31 vorgesehen sein. Die Dichtungsschicht 31 kann aus einer Dichtfolie oder einem anderen Dichtmaterial bestehen und die fluidische Dichtheit zwischen Folie 13 und Trägerelement 12 herstellen. Die Dichtungsschicht 31 kann auch durch eine Klebefuge aus Klebstoff gebildet werden, mittels der die Folie 13 an der Befestigungsfläche des Bodens 26 befestigt ist.As this according to the FIGS. 3 and 4 is illustrated, a sealing layer 31 may be provided between the film 13 and the bottom 26 of the recess 25. The sealing layer 31 may consist of a sealing film or another sealing material and the fluidic tightness produce between the film 13 and support member 12. The sealing layer 31 can also be formed by an adhesive glue joint, by means of which the film 13 is fastened to the fastening surface of the bottom 26.

Bei der in den Figuren 1-4 dargestellten Ausführungsform verläuft der Boden 26 in einer Ebene, die rechtwinklig zu der durch den Fluidkanal 20 definierten Strömungsrichtung 21 ausgerichtet ist. Die zylindrischen Düsenöffnungen 15 sind rechtwinklig zur Erstreckungsebene in die Folie 13 eingebracht, so dass die Abstrahlrichtung des aus den Düsenöffnungen austretenden Fluidstrahls der Strömungsrichtung 21 entspricht.In the in the Figures 1-4 In the embodiment shown, the bottom 26 extends in a plane which is aligned at right angles to the flow direction 21 defined by the fluid channel 20. The cylindrical nozzle openings 15 are introduced into the film 13 at right angles to the plane of extent, so that the emission direction of the fluid jet emerging from the nozzle openings corresponds to the flow direction 21.

In Figur 5 ist eine abgewandelte Ausführungsform dargestellt, bei der der Boden 26 um einen Neigungswinkel β gegenüber einer Bezugsebene E quer zur Längsrichtung 11 seitlich geneigt verläuft. Die Bezugsebene E ist rechtwinklig zur Strömungsrichtung 21 ausgerichtet. Die Bezugsebene E kann auch eine horizontale Ebene sein, gegenüber der der Boden 26 in Gebrauchslage des Düsenstreifens 10 geneigt ist. Auf diese Weise kann die Abstrahlrichtung des aus den Düsenöffnungen austretenden Fluidstrahls sehr einfach eingestellt werden, ohne dass hierfür eine Veränderung an der Folie 13 oder an den Düsenöffnungen 15 notwendig wäre. Die veränderte Abstrahlrichtung des Fluidstrahls kann zur Folge haben, dass die Größe des Fluidkanals 20 entsprechend angepasst werden muss, so dass der Fluidstrahl berührungslos durch den Fluidkanal 20 fliesen und auf das Wirrfasergelege wirken kann. In die Vertiefung 25 mit der geneigten Befestigungsfläche 26 kann dieselbe Folie 13 wie beim ersten Ausführungsbeispiel gemäß den Figuren 1-4 mit oder ohne Dichtungsschicht 31 eingesetzt werden.In FIG. 5 a modified embodiment is shown in which the bottom 26 extends laterally inclined by an inclination angle β relative to a reference plane E to the longitudinal direction 11. The reference plane E is aligned at right angles to the flow direction 21. The reference plane E may also be a horizontal plane, with respect to which the base 26 is inclined in the position of use of the nozzle strip 10. In this way, the emission direction of the fluid jet emerging from the nozzle openings can be set very easily, without a change to the film 13 or to the nozzle openings 15 being necessary for this purpose. The changed emission direction of the fluid jet may result in the size of the fluid channel 20 having to be adapted accordingly so that the fluid jet can contact the fluid channel 20 without contact and act on the fiber web. In the recess 25 with the inclined mounting surface 26, the same film 13 as in the first embodiment according to the Figures 1-4 be used with or without sealing layer 31.

Wie dies bereits in Zusammenhang mit Figur 1 erläutert wurde, verlaufen die Folien 13 um den Winkel α schräg zur Längsrichtung 11 des Trägerelements 12. Entsprechend verlaufen die Vertiefungen 25 und die Eingangsmündungen 23 des Fluidkanals 20 des Trägerelements 12 in Draufsicht auf das Trägerelement 12 schräg zur Längsrichtung 11 unter dem Winkel α. Diese Richtung ist als Erstreckungsrichtung 35 bezeichnet.As already related to FIG. 1 explained Accordingly, the recesses 25 and the inlet openings 23 of the fluid channel 20 of the carrier element 12 extend in a plan view of the carrier element 12 obliquely to the longitudinal direction 11 at the angle α. This direction is referred to as the extension direction 35.

Zwei unmittelbar benachbarte Vertiefungen 25 sind in Erstreckungsrichtung 35 gesehen parallel versetzt zueinander angeordnet. In Erstreckungsrichtung 35 verlaufen die Vertiefungen 25 nicht in einer Flucht. In einem Überlappungsbereich 36 verlaufen zwei unmittelbar benachbarte Vertiefungen 25 in Erstreckungsrichtung 35 nebeneinander (Figur 2). Ein Endabschnitt 37 einer Folie 13 ist daher in Erstreckungsrichtung 35 neben dem zugeordneten Endabschnitt 37 der benachbarten Folie 13 angeordnet. Beim Ausführungsbeispiel des Düsenstreifens 10 gemäß der Figuren 1-5 sind vollständig umrandete Vertiefungen 25 vorgesehen, die durch einen Steg 39 voneinander getrennt sind.Two immediately adjacent recesses 25 are arranged offset in the extension direction 35 parallel to each other. In the extension direction 35, the recesses 25 do not run in alignment. In an overlapping region 36, two immediately adjacent recesses 25 extend in the extension direction 35 next to each other ( FIG. 2 ). An end section 37 of a film 13 is therefore arranged in the extension direction 35 next to the associated end section 37 of the adjacent film 13. In the embodiment of the nozzle strip 10 according to the Figures 1-5 are completely outlined depressions 25 are provided, which are separated by a web 39 from each other.

Bei einer abgewandelten Ausführungsvariante des Düsenstreifens 10 sind zwei unmittelbar benachbarte Vertiefungen 25 im Überlappungsbereich 36 miteinander verbunden. Durch diese Maßnahme besteht die Möglichkeit, die beiden aneinander angrenzenden Folien 13 durch an den Endbereichen 37 der Folien 13 vorgesehenen Verbindungsmitteln 40 miteinander zu verbinden.In a modified embodiment variant of the nozzle strip 10, two immediately adjacent depressions 25 are connected to one another in the overlapping region 36. By this measure, it is possible to connect the two adjoining films 13 with one another by connecting means 40 provided at the end regions 37 of the films 13.

Eine solche Ausgestaltung ist schematisch in Figur 7 veranschaulicht, wobei der Übersicht halber die Düsenöffnungen 15 nicht dargestellt sind. Es ist lediglich die äußere Kontur der Folie 13 veranschaulicht. Als Verbindungsmittel 40 weist jede Folie 13 an einem Endabschnitt 37 einen oder mehrere Verbindungsvorsprünge 41 auf, die quer zur Erstreckungsrichtung 35 vom Endabschnitt 37 wegragen. An ihrem zugeordneten Endabschnitt 37 weist die benachbarte Folie 13 eine oder mehrere Verbindungsausnehmungen 42 auf, in die die Verbindungsvorsprünge 41 bei hergestellter Verbindung zweier Folien 13 eingreifen. Dadurch wird eine formschlüssige Verbindung hergestellt. Die Verbindungsvorsprünge 41 erweitern sich zu ihrem freien Ende hin und sind beispielsgemäß gewölbt ausgeführt ähnlich wie die Verbindungselemente von Puzzleteilen.Such an embodiment is shown schematically in FIG FIG. 7 illustrated, for the sake of clarity, the nozzle openings 15 are not shown. It is only the outer contour of the film 13 illustrated. As a connecting means 40, each film 13 at an end portion 37 a or a plurality of connecting projections 41 which protrude transversely to the extension direction 35 from the end portion 37. At its associated end section 37, the adjacent film 13 has one or more connecting recesses 42 into which the connecting projections 41 engage when the two films 13 have been produced. As a result, a positive connection is established. The connecting protrusions 41 expand towards their free end and, for example, are arched, similar to the connecting elements of puzzle pieces.

Die Verbindungsausnehmungen 42 sind an die Kontur der Verbindungsvorsprünge 41 angepasst. Beim hier beschriebenen Ausführungsbeispiel nach Figur 7 sind die Verbindungsausnehmungen 42 in einem seitlich von der Folie 13 abstehenden Vorsprung 43 vorgesehen, der eben mit der Außenseite 18 der Folie 13 verläuft und dessen Dicke geringer ist, als die Dicke der übrigen Folie 13, wodurch im Bereich unter den Verbindungsausnehmungen 42 ein Freiraum 44 gebildet ist. Unterhalb der Verbindungsvorsprünge 41 ist ein Auflageelement 45 vorhanden, auf dem der Vorsprung 43 aufliegt, wenn die Verbindungsvorsprünge 4 in die Verbindungsausnehmungen 42 eingreifen. Die Kontur des Auflageelements 45 ist beim Ausführungsbeispiel an die Kontur des Freiraums 44 angepasst.The connection recesses 42 are adapted to the contour of the connection projections 41. According to the embodiment described here FIG. 7 the connecting recesses 42 are provided in a projection 43 projecting laterally from the film 13, which runs flat with the outside 18 of the film 13 and whose thickness is smaller than the thickness of the remaining film 13, whereby a clearance 44 is provided in the area below the connecting recesses 42 is formed. Below the connecting projections 41 there is a support element 45, on which the projection 43 rests when the connecting projections 4 engage in the connecting recesses 42. The contour of the support element 45 is adapted in the embodiment of the contour of the free space 44.
