Weiterhin betrifft die vorliegende Erfindung eine Sauglippenanordnung für eine Saugleiste.The present invention relates to a squeegee for sucking a substrate according to the preamble of claim 1. Furthermore, the present invention relates to a squeegee assembly for a squeegee.

Saugleisten werden in Bodenbearbeitungseinrichtungen verwendet bzw. verbaut, die wiederum Bestandteile von Bodenbearbeitungsmaschinen sein können. Dabei können diese Saugleisten in einem Gehäuse der Bodenbearbeitungseinrichtung integriert sein, oder können separat in der Bodenbearbeitungsmaschine verbaut sein. Bodenbearbeitungsmaschinen werden beispielsweise zur Säuberung eines Untergrunds eingesetzt, auf dem beispielsweise ein Wasserfilm aufgetragen wird, der von der Saugleiste aufgesaugt wird.Suction molds are used or installed in soil tillage equipment, which in turn may be components of tillage machines. These suction strips can be integrated in a housing of the soil treatment device, or can be installed separately in the tillage machine. Tillage machines are used for example for cleaning a substrate on which, for example, a film of water is applied, which is absorbed by the squeegee.

Aus dem Stand der Technik bekannte Saugleisten weisen eine Absaugkammer auf, aus der mittels einem Sauganschluss ein sich in der Absaugkammer befindliches Medium, so wie beispielsweise ein Luft-Wasser-Gemisch oder ein Gemisch aus Luft und Staubpartikeln abgesaugt werden kann. Die Absaugkammer weist dazu eine zum Untergrund hin gerichtete Absaugöffnung auf. An zwei Längsseiten der Absaugkammer sind eine vorlaufende Sauglippe und eine nachlaufende Sauglippe angeordnet, die üblicherweise aus einem elastischen Material bestehen. Die Sauglippen ragen über die Absaugöffnung der Saugleiste hinaus und sind mit dem zu reinigenden Untergrund in Kontakt bringbar. Dabei ist die vorlaufende Sauglippe an der Längsseite der Absaugkammer angeordnet, die in Fahrtrichtung bzw. Verschieberichtung der Saugleiste orientiert ist, und die nachlaufende Sauglippe ist auf der gegenüberliegenden Längsseite der Absaugkammer angeordnet.Suction bars known from the prior art have a suction chamber, from which a medium located in the suction chamber, such as, for example, an air-water mixture or a mixture of air and dust particles, can be sucked off by means of a suction connection. The suction chamber has for this purpose a directed toward the ground suction. On two longitudinal sides of the suction chamber, a leading suction lip and a trailing suction lip are arranged, which usually consist of an elastic material. The squeezing lips protrude beyond the suction opening of the squeegee and can be brought into contact with the substrate to be cleaned. In this case, the leading suction lip is arranged on the longitudinal side of the suction chamber, which is oriented in the direction of travel or displacement direction of the suction strip, and the trailing suction lip is arranged on the opposite longitudinal side of the suction chamber.

Bei den aus dem Stand der Technik bekannten Saugleisten werden die separaten vorlaufenden und nachlaufenden Sauglippen in der Absaugkammer getrennt voneinander befestigt. Die Montage einer entsprechenden Saugleiste ist aufwendig, da die Sauglippen in mehreren Arbeitsschritten separat an der Absaugkammer befestigt werden. Darüber hinaus müssen die Sauglippen für die Montage auf einen Spannring gesteckt werden. Folglich besteht eine aus dem Stand der Technik bekannte Saugleiste aus vielen Einzelteilen, die miteinander verbunden werden müssen.In the case of the suction strips known from the prior art, the separate leading and trailing squeezing lips are fastened separately from one another in the suction chamber. The installation of a corresponding squeegee is expensive, since the squeegee be attached separately in several steps to the suction chamber. In addition, the squeegee must be plugged for mounting on a clamping ring. Consequently, there is a known from the prior art squeegee of many items that need to be connected together.

Die FR 2 044 749 A2 offenbart eine Feuchtigkeitsabsaugdüse für mit einer Saugwirkung arbeitende Reinigungsvorrichtungen. Die Feuchtigkeitsabsaugdüse umfasst einen Düsenkörper, in dem ein aus einem Elastomermaterial gebildetes Quetschorgan eingelassen ist. Das Quetschorgan weist dabei eine dem Aufnahmeraum des Düsenkörpers entsprechende räumliche Form mit einem U-förmigen Querschnitt auf. Das Quetschorgan umfasst in dessen Mittelsteg mehrere Schlitze, durch die Luft und Flüssigkeit ungehindert hindurchströmen können. Das Quetschorgan ist mittels eines Halteteils und mittels Schrauben an dem Düsenkörper befestigt. Weiterhin umfasst die Feuchtigkeitsabsaugdüse eine Filterschiene, die in dem Halteteil befestigt ist.The FR 2 044 749 A2 discloses a moisture suction nozzle for suction cleaning devices. The moisture suction nozzle comprises a nozzle body, in which a pinch member formed from an elastomeric material is embedded. The squeezing organ has a spatial shape corresponding to the receiving space of the nozzle body with a U-shaped cross section. The pinch member comprises in its central web a plurality of slots through which air and liquid flow unhindered can. The squeezing member is fixed by means of a holding part and by means of screws to the nozzle body.

Die WO 2007/092322 A2 offenbart eine Saugleistenbaugruppe, die ein Wischerblatt mit Befestigungsöffnungen und Positionierungsöffnungen, eine Befestigungsklammer mit Positionierungsstiften und einen Haltebügel mit Positionierungsöffnungen umfasst. Das Wischerblatt ist zwischen der Befestigungsklammer und dem Haltebügel angeordnet und dadurch zwischen diesen gehalten, dass eine Gewindestift jeweils durch in dem Haltebügel, in dem Wischerblatt und die der Befestigungsklammer vorgesehenen Befestigungsöffnungen hindurchgesteckt ist und auf Seiten der Befestigungsklammer und des Haltebügels gesichert ist. Dabei ragen die Positionierungsstifte der Befestigungsklammer durch die Positionierungsöffnungen des Wischerblatts, so dass das Wischerblatt in der richtigen Orientierung zwischen der Befestigungsklammer und dem Haltebügel befestigt ist.The WO 2007/092322 A2 discloses a squeegee assembly comprising a wiper blade with mounting holes and locating holes, a mounting bracket with locating pins, and a headband with locating holes. The wiper blade is disposed between and held between the mounting bracket and the bracket by threading a threaded pin through mounting holes provided in the bracket, the wiper blade, and the mounting bracket, respectively, and secured to the mounting bracket and the bracket. In this case, the positioning pins of the mounting bracket protrude through the positioning holes of the wiper blade, so that the wiper blade is mounted in the correct orientation between the mounting bracket and the headband.

Aufgabe der vorliegenden Erfindung ist die Bereitstellung einer einfacher herzustellenden, leicht montierbaren bzw. demontierbaren, stabileren und kostengünstigeren Saugleiste.Object of the present invention is to provide a more easily manufactured, easy to assemble or disassemble, more stable and cheaper squeegee.

Die Aufgabe wird erfindungsgemäß entsprechend den in Anspruch 1 angegebenen kennzeichnenden Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved according to the characterizing features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Eine Erfindungsgemäße Saugleiste zum Absaugen eines Untergrunds umfasst einen blattförmigen Sauglippen-Zuschnitt, der eine Durchgangsöffnung aufweist. Dieser Sauglippen-Zuschnitt wird mittels einer Niederhalteeinrichtung in der Absaugkammer befestigt. Dabei passt sich der Sauglippen-Zuschnitt dem U-förmigen Querschnitt der Absaugkammer so an, dass die vorlaufende Sauglippe und die nachlaufende Sauglippe durch sich gegenüberliegende und aus der Absaugöffnung hinaus ragende Längsseitenflächen des Sauglippen-Zuschnitts gebildet sind. Die vorlaufende Sauglippe und die nachlaufende Sauglippe sind somit über einen Mittelabschnitt miteinander verbunden bzw. hängen über diesen Mittelabschnitt miteinander zusammen. Dabei ist die Durchgangsöffnung des Sauglippen-Zuschnitts und der Sauganschluss der Ansaugkammer so zueinander angeordnet, dass diese einen gemeinsamen Durchgang bilden, durch den das abzusaugende Medium abgesaugt werden kann.A suction strip according to the invention for sucking a substrate comprises a blade-shaped squeegee blank having a through opening. This squeegee blank is fastened in the suction chamber by means of a hold-down device. In this case, the squeegee blank adapts to the U-shaped cross-section of the suction chamber in such a way that the leading suction lip and the trailing suction lip are formed by longitudinal side surfaces of the squeegee blank protruding from and protruding out of the suction opening. The leading suction lip and the trailing suction lip are thus connected to each other via a central portion or hang together via this central portion. In this case, the passage opening of the suction lip blank and the suction port of the suction chamber are arranged relative to one another such that they form a common passage through which the medium to be sucked off can be sucked off.

Eine erfindungsgemäße Saugleiste weist den Vorteil auf, dass die Saugleiste aus nur wenigen Einzelteilen besteht. Daher ist die Montage einer erfindungsgemäßen Saugleiste vereinfacht. Für die Montage muss lediglich der blattförmige Sauglippen-Zuschnitt auf die Absaugöffnung bzw. die Saugfläche der Absaugkammer positioniert werden und mittels der Niederhalteeinrichtung in die Absaugkammer gedrückt werden. Der aus einem elastischen Material gebildete blattartige Sauglippen-Zuschnitt passt sich dabei der U-förmigen Kontur der Absaugkammer so an, dass die über die Absaugöffnung hinaus ragenden Längsseitenflächen die vorlaufende Sauglippe und die nachlaufende Sauglippe bilden. Dabei müssen die Durchgangsöffnung und der Sauganschluss einen gemeinsamen Durchgang bilden, durch den das abzusaugende Medium abgesaugt werden kann. Eine erfindungsgemäße Saugleiste weist aufgrund der wenigen Einzelteile, aus der diese gebildet ist, eine erhöhte Stabilität auf und ist kostengünstig herzustellen.A suction strip according to the invention has the advantage that the squeegee consists of only a few individual parts. Therefore, the assembly of a suction strip according to the invention is simplified. For assembly, only the sheet-shaped squeegee blank has to be positioned on the suction opening or the suction surface of the suction chamber and pressed into the suction chamber by means of the hold-down device. The sheet-shaped suction lip blank formed from an elastic material adapts to the U-shaped contour of the suction chamber so that the longitudinal side surfaces projecting beyond the suction opening form the leading suction lip and the trailing suction lip. In this case, the passage opening and the suction connection must form a common passage through which the medium to be sucked off can be sucked off. A suction strip according to the invention has due to the few items, from which it is formed, increased stability and is inexpensive to manufacture.

Bevorzugt weist dabei der Sauglippen-Zuschnitt zwei vordefinierte Sollbiegelinien auf, entlang derer der Sauglippen-Zuschnitt biegbar ist. Diese Sollbiegelinien verlaufen parallel zu den die Längsseitenflächen begrenzende Längsseiten des Sauglippen-Zuschnitts. Durch die Sollbiegelinien wird der Sauglippen-Zuschnitt in zwei Längsseitenflächen und einen mittigen Mittelabschnitt unterteilt. Dabei entspricht die Form des Mittelabschnitts vorzugsweise der Form der Seite der Absaugkammer, mit die der Mittelabschnitt des Sauglippen-Zuschnitts in direktem Kontakt steht. Aufgrund der Sollbiegelinien können sich die Längsseitenflächen des Sauglippen-Zuschnitts besser der U-förmigen Kontur der Absaugkammer anpassen, da aufgrund der Sollbiegelinien ein kleinerer Biegeradius zwischen den Längsseitenflächen und dem Mittelabschnitt möglich ist.In this case, the squeegee blank preferably has two predefined predetermined bending lines along which the squeegee blank can be bent. These predetermined bending lines run parallel to the longitudinal sides limiting the longitudinal sides of the squeegee blank. Due to the predetermined bending lines of the squeegee blank is divided into two longitudinal side surfaces and a central middle section. In this case, the shape of the middle section preferably corresponds to the shape of the side of the suction chamber with which the middle section of the suction lip blank is in direct contact. Due to the predetermined bending lines, the longitudinal side surfaces of the suction lip blank can better adapt to the U-shaped contour of the suction chamber, since a smaller bending radius between the longitudinal side surfaces and the central portion is possible due to the predetermined bending lines.

Bevorzugt verjüngt sich die Saugkammer entlang deren Längsausdehnung zu den Randbereichen hin und weist an den Querseiten Randöffnungen auf. Der mittels der Niederhalteeinrichtung in der Absaugkammer befestigte Sauglippen-Zuschnitt ragt dabei aus den Randöffnungen heraus. Die aus der Saugkammer heraus ragenden Teilbereiche des Sauglippen-Zuschnitts werden durch die Verjüngung der Saugkammer aufeinander zugebogen und stehen miteinander in Kontakt. Bei einer entsprechenden Ausgestaltung der Saugleiste sind die Querseiten der Saugkammer auf eine besonders einfache Art und Weise durch den Sauglippen-Zuschnitt verschlossen, so dass in der Saugkammer zuverlässig ein Unterdruck gegenüber der Umgebung aufgebaut werden kann.Preferably, the suction chamber tapers along its longitudinal extent to the edge regions and has edge openings on the transverse sides. The suction lip blank fastened in the suction chamber by means of the hold-down device protrudes from the edge openings. The protruding from the suction chamber portions of the Sauglippen blank are bent towards each other by the taper of the suction chamber and are in contact with each other. In a corresponding embodiment of the squeegee, the transverse sides of the suction chamber are closed in a particularly simple manner by the squeegee blank, so that in the suction chamber reliably a negative pressure relative to the environment can be established.

Bevorzugt weist dabei der Sauglippen-Zuschnitt an Querseitenflächen Aussparungen auf, die zu den Längsseitenflächen beabstandet sind. Aufgrund dieser Aussparungen ist gewährleistet, dass die durch die Längsseitenflächen des Sauglippen-Zuschnitts gebildeten vorlaufenden und nachlaufenden Sauglippen im montierten Zustand in einer Ebene liegen, obwohl sich der Sauglippen-Zuschnitt dem sich zu den Randbereichen der Saugkammer verjüngenden Querschnitt anpasst. Hierdurch wird ein ebenes Aufliegen der vorlaufenden Sauglippe und der nachlaufenden Sauglippe auf dem Untergrund gewährleistet.In this case, the squeegee blank preferably has recesses on transverse side surfaces, which are spaced apart from the longitudinal side surfaces. Because of these recesses, it is ensured that the leading and trailing squeezing lips formed by the longitudinal side surfaces of the squeegee blank are in one plane when assembled, although the squeegee blank adapts to the cross-section tapering to the edge regions of the suction chamber. As a result, a level contact of the leading suction lip and the trailing suction lip is ensured on the ground.

Die Saugleiste umfasst eine Absaugkammer 10, einen blattförmigen Sauglippen-Zuschnitt 20 und eine Niederhalteeinrichtung 30. Figuren 3 und 4 zeigen die in dem Gehäuse 100 einer Bodenbearbeitungseinrichtung integrierte erfindungsgemäße Saugleiste in einem montierten Zustand, in dem der Sauglippen-Zuschnitt 20 mittels der Niederhalteeinrichtung 30 in der Absaugkammer 10 befestigt ist.The suction strip according to the invention is in the FIGS. 1 and 2 shown in a disassembled state. The squeegee comprises a suction chamber 10, a blade-shaped squeegee blank 20 and a hold-down device 30. Figures 3 and 4 show the integrated in the housing 100 of a tillage device according to the invention the suction strip in an assembled state in which the squeegee blank 20 is secured by means of the hold-down device 30 in the suction chamber 10.

Die Absaugkammer 10 der Saugleiste ist durch zwei Längsseiten 11, 11' und zwei Querseiten 12 begrenzt. Aus den Figuren 3 und 4 ist ersichtlich, dass die die Grundfläche der Absaugkammer bildende Abschlusswand einen Sauganschluss 13 aufweist, der mit einem Saugkanal verbunden ist. Dieser Saugkanal ist wiederum mit einem Gebläse zur Erzeugung eines Unterdrucks verbunden. Die die Längsseiten 11, 11' und die Querseiten 12 begrenzende Fläche bildet die zum Untergrund hin gerichtete Absaugöffnung 14 bzw. Absaugfläche 14. Entlang der Längsausdehnung der Saugkammer verkleinert sich der Abstand der Längsseiten 11, 11' zueinander, so dass sich die Absaugkammer 10 entlang deren Längsausdehnung zu den Randbereichen hin verjüngt. Dabei weist die Absaugkammer 10 an den beiden Querseiten 12 jeweils eine Randöffnung 15 auf. Die Absaugkammer 10 weist einen quer zu den Längsseiten 11, 11' verlaufenden U-förmigen Querschnitt auf.The suction chamber 10 of the suction strip is bounded by two longitudinal sides 11, 11 'and two transverse sides 12. From the Figures 3 and 4 It can be seen that the end wall forming the base area of the suction chamber has a suction connection 13, which is connected to a suction channel. This suction channel is in turn connected to a blower to generate a negative pressure. The longitudinal sides 11, 11 'and the transverse sides 12 bounding surface forms the suction towards the ground 14 or suction surface 14. Along the longitudinal extent of the suction chamber the distance of the longitudinal sides 11, 11 'from each other decreases, so that the suction chamber 10 tapers along its longitudinal extent to the edge regions. In this case, the suction chamber 10 at the two transverse sides 12 each have an edge opening 15. The suction chamber 10 has a transverse to the longitudinal sides 11, 11 'extending U-shaped cross-section.

Der in Figur 1 oberhalb der Absaugkammer gezeigte blattförmige Sauglippen-Zuschnitt 20 ist in Figur 5 in einer Draufsicht separat dargestellt. Der Sauglippen-Zuschnitt besteht bevorzugt aus einem elastischen Material und umfasst zwei Längsseitenflächen 22, 22', zwei Querseitenflächen 26 und einen Mittelabschnitt 23. Dabei sind die Sollbiegelinien 24 zwischen dem Mittelabschnitt 23 und den zwei Längsseitenflächen 22, 22' angeordnet. Die Oberfläche des Sauglippen-Zuschnitts 20 kann glatt und eben ausgestaltet sein. Jedoch kann die Oberfläche des Sauglippen-Zuschnitts auch eine Wellenstruktur mit Wellenkämmen und Wellentälern aufweisen, die sich von einer Längsseite 22 zur anderen Längsseite 22' erstrecken.The in FIG. 1 Leaf-shaped suction lip blank 20 shown above the suction chamber is in FIG. 5 shown separately in a plan view. The squeegee blank preferably consists of an elastic material and comprises two longitudinal side surfaces 22, 22 ', two transverse side surfaces 26 and a middle section 23. The predetermined bending lines 24 are arranged between the central section 23 and the two longitudinal side surfaces 22, 22'. The surface of the squeegee blank 20 may be smooth and planar. However, the surface of the squeegee blank may also have a wave structure with crests and troughs extending from one longitudinal side 22 to the other longitudinal side 22 '.

Die Sollbiegelinien 24 können beispielsweise durch eine Vorbiegung des Sauglippen-Zuschnitts 20 erzeugt werden. Weiterhin können die Sollbiegelinien 24 auch durch eine Verjüngung der Materialstärke des Sauglippen-Zuschnitts 20 realisiert sein. Eine weitere Möglichkeit zur Erzeugung der Sollbiegelinien 24 ist ein Anschneiden bzw. Einschneiden des Sauglippen-Zuschnitts 20, wobei darauf zu achten ist, dass die Längsseitenflächen 22, 22' durch den Mittelabschnitt 23 verbunden bleiben müssen. Bei einer Ausgestaltung des Sauglippen-Zuschnitts 20 aus einem eine Wellenstruktur aufweisenden blattförmigen Material mit Wellenkämmen und Wellentälern können die Sollbiegelinien 24 durch Anschneiden bzw. Einschneiden der Wellenkämme realisiert sein.The predetermined bending lines 24 can be generated, for example, by a pre-bending of the squeegee blank 20. Furthermore, the predetermined bending lines 24 can also be realized by a tapering of the material thickness of the suction-lip blank 20. Another possibility for generating the predetermined bending lines 24 is a cutting or cutting of the squeegee blank 20, wherein care must be taken that the longitudinal side surfaces 22, 22 'remain connected by the central portion 23. In one embodiment of the squeegee blank 20 made of a wave structure having sheet material with wave crests and troughs, the predetermined bending lines 24 may be realized by cutting or cutting the wave crests.

Im Mittelbereich des Mittelabschnitts 23 ist eine Durchgangsöffnung 21 angeordnet. Neben der Durchgangsöffnung 21 sind zu den Querseiten des Sauglippen-Zuschnitts 20 hin zwei Halteeinrichtungen 28 in Form von Halteöffnungen 28 vorgesehen. Der Sauglippenzuschnitt 20 weist an den Querseitenflächen 26 Aussparungen 27 auf, die zu den Längsseitenflächen 22, 22' hin beabstandet sind.In the central region of the central portion 23, a through hole 21 is arranged. In addition to the passage opening 21, two holding devices 28 in the form of holding openings 28 are provided toward the transverse sides of the suction lip blank 20. The Sauglippenzuschnitt 20 has on the transverse side surfaces 26 recesses 27, which are spaced from the longitudinal side surfaces 22, 22 'out.

Die vorlaufende Sauglippe 16 und die nachlaufende Sauglippe 16' der Saugleiste werden dadurch gebildet, dass der Sauglippen-Zuschnitt 20 mittels der in den Figuren 1 und 2 einstückig ausgebildeten Niederhalteeinrichtung in der Absaugkammer 10 befestigt wird. Die Niederhalteeinrichtung 30 weist eine Öffnung 31 und zwei Befestigungseinrichtungen 32 in Form von Haltestiften 32 auf. Im montierten Zustand ist die Öffnung 31 oberhalb der Durchgangsöffnung 21 des SaugplippenZuschnitts 20 positioniert, damit ein funktionstüchtiger Saugkanal geschaffen ist. Die Niederhalteeinrichtung 30 muss nicht notwendigerweise einstückig ausgebildet sein, sondern kann auch mehrstückig ausgebildet sein.The leading suction lip 16 and the trailing suction lip 16 'of the squeegee are formed by the squeegee blank 20 by means of the in the FIGS. 1 and 2 integrally formed holding-down device is mounted in the suction chamber 10. The hold-down device 30 has an opening 31 and two fastening devices 32 in the form of retaining pins 32. In the assembled state, the opening 31 is positioned above the passage opening 21 of the SaugplippenZuschnitts 20 so that a functional suction channel is created. The hold-down device 30 does not necessarily have to be formed in one piece, but may also be formed in several pieces.

Der Sauglippen-Zuschnitt 20 wird mittels der Niederhalteeinrichtung 30 in die Absaugkammer 10 gedrückt, so dass sich der Sauglippen-Zuschnitt 20 dem U-förmigen Querschnitt der Absaugkammer 10 anpasst. Der Mittelabschnitt 23 des Sauglippen-Zuschnitts 20 liegt dann an der Wand der Absaugkammer 10 an, in der der Sauganschluss 13 ausgebildet ist. Dabei bilden die Durchgangsöffnung 21 des Sauglippen-Zuschnitts 20 und der Sauganschluss 13 einen gemeinsamen Durchgang, da die Durchgangsöffnung 21 oberhalb der Ansaugöffnung 13 angeordnet ist. Die Längsseitenflächen 22, 22' werden um die Sollbiegelinien 24 gebogen und schmiegen sich an die Längsseiten 11, 11' der Absaugkammer 10. Dabei ist die Querausdehnung der Längsseitenflächen 22, 22' größer als die entsprechende Querausdehnung der Längsseiten 11, 11' der Absaugkammer 10, so dass die Längsseitenflächen 22, 22' aus der Absaugöffnung 14 der Absaugkammer 10 heraus ragen. Somit bildet die Längsseitenfläche 22 die vorlaufende Sauglippe 16, und die Längsseitenfläche 22' bildet die nachlaufende Sauglippe 16'. Dabei sind die Längsseitenflächen 22, 22' über den Mittelabschnitt 23 miteinander verbunden.The squeegee blank 20 is pressed into the suction chamber 10 by means of the hold-down device 30, so that the squeegee blank 20 adapts to the U-shaped cross-section of the suction chamber 10. The central portion 23 of the squeegee blank 20 then abuts against the wall of the suction chamber 10, in which the suction port 13 is formed. In this case, the passage opening 21 of the Suction lip blank 20 and the suction port 13 a common passage, since the passage opening 21 is disposed above the suction port 13. The longitudinal side surfaces 22, 22 'are bent around the predetermined bending lines 24 and nestle against the longitudinal sides 11, 11' of the suction chamber 10. The transverse extent of the longitudinal side surfaces 22, 22 'is greater than the corresponding transverse extent of the longitudinal sides 11, 11' of the suction chamber 10 , so that the longitudinal side surfaces 22, 22 'protrude out of the suction opening 14 of the suction chamber 10. Thus, the longitudinal side surface 22 forms the leading suction lip 16, and the longitudinal side surface 22 'forms the trailing suction lip 16'. The longitudinal side surfaces 22, 22 'are connected to each other via the central portion 23.

Die Haltestifte 32 der Niederhalteeinrichtung 30 ragen im montierten Zustand durch die Halteöffnungen 28 des Sauglippen-Zuschnitts 20 und ragen ebenfalls durch die Wandung der Absaugkammer 10, in der der Sauganschluss 13 vorgesehen ist. An der Außenseite der Saugleiste können die Haltestift gesichert werden. Dadurch ist ein Verschieben des Sauglippen-Zuschnitts 20 gegenüber der Absaugkammer 10 nicht möglich.The retaining pins 32 of the hold-down device 30 protrude in the assembled state through the holding openings 28 of the Sauglippen blank 20 and also project through the wall of the suction chamber 10, in which the suction port 13 is provided. The retaining pin can be secured on the outside of the squeegee. As a result, a displacement of the squeegee blank 20 with respect to the suction chamber 10 is not possible.

Aus den Figuren 3 und 4 ist ersichtlich, dass der Sauglippen-Zuschnitt 20 im montierten Zustand aus den Randöffnungen 15 heraus ragt. Dabei werden die aus der Saugkammer 10 heraus ragenden Teilbereiche 25 des Sauglippen-Zuschnitts 20 durch die Verjüngung der Saugkammer 10 aufeinander zu gebogen und stehen miteinander in Kontakt. Aufgrund des in der Saugkammer 10 erzeugten Unterdrucks werden in den Teilbereichen 25 die Längsseitenflächen 22 und 22' aufeinander zugedrückt.From the Figures 3 and 4 It can be seen that the squeegee blank 20 protrudes out of the edge openings 15 in the mounted state. The protruding from the suction chamber 10 portions 25 of the Sauglippen blank 20 are bent by the taper of the suction chamber 10 to each other and are in contact. Due to the negative pressure generated in the suction chamber 10, the longitudinal side surfaces 22 and 22 'are pressed towards one another in the partial regions 25.

Aus Figur 3 ist ersichtlich, dass die vorlaufende Sauglippe 16, 22 ein wenig weiter aus der Absaugkammer 10 herausragt als die nachlaufende Sauglippe 16', 22'. Weiterhin ist es aber auch möglich, dass die vorlaufende Sauglippe 16, 22 und die nachlaufende Sauglippe 16', 22' in einer Ebene liegen. Zumindest ragt aber die vorlaufende Sauglippe 16, 22 über die gesamte Längsseite 11 gleich weit aus der Absaugkammer 10. Selbiges gilt für die nachlaufende Sauglippe 16', 22' bezüglich der Längsseite 11' der Absaugkammer 10. Diese ebene Ausgestaltung der vorlaufenden Sauglippe 16, 22 und der nachlaufenden Sauglippe 16', 22' wird trotz Verjüngung der Absaugkammer dadurch möglich, dass der Sauglippen-Zuschnitt 20 an den Querseitenflächen 26 die Aussparungen 27 aufweist. Ohne entsprechende Aussparungen 27 an den Querseitenflächen 26 würden in den Randbereichen der Saugkammer 10, in denen sich der Querschnitt der Saugkammer 10 verjüngt, die Längsseitenflächen 22, 22' weiter aus der Absaugöffnung 14 heraus ragen als die Längsseitenflächen 22, 22' im Mittelbereich der Absaugkammer 10, wo der Querschnitt dieser nicht verjüngt ist.Out FIG. 3 it can be seen that the leading suction lip 16, 22 protrudes a little further from the suction chamber 10 as the trailing suction lip 16 ', 22'. Furthermore, it is also possible that the leading suction lip 16, 22 and the trailing suction lip 16 ', 22' lie in a plane. But at least the leading suction lip 16, 22 extends over the entire longitudinal side 11 equidistant from the suction chamber 10. The same applies to the trailing suction lip 16 ', 22' with respect to the longitudinal side 11 'of the suction chamber 10. This planar configuration of the leading suction lip 16, 22nd and the trailing suction lip 16 ', 22' is in spite of tapering of the suction possible in that the squeegee blank 20 on the transverse side surfaces 26, the recesses 27 has. Without corresponding recesses 27 on the transverse side surfaces 26, in the edge regions of the suction chamber 10, in which the cross section of the suction chamber 10 tapers, the longitudinal side surfaces 22, 22 'protrude further out of the suction opening 14 than the longitudinal side surfaces 22, 22' in the middle region of the suction chamber 10, where the cross-section of this is not tapered.
