Stand der TechnikState of the art

Aus dem Stand der Technik sind Reinigungsgeräte bekannt, welche handbetätigt über zu reinigende Oberflächen geschoben werden können. Bei der Relativbewegung zwischen Reinigungsgerät und zu reinigender Oberfläche wird Schmutz aufgenommen. In der DE 10 2007 061 607 A1 wird beispielsweise ein handbetätigtes Handreinigungsgerät beschrieben, welches unter anderem eine angetriebene rotierbare Bürstenrolle aufweist. Durch die Bürstenrolle wird Schmutz in einen direkt angrenzend angeordneten Schmutzbehälter transportiert. Die Bürstenrolle ist dabei mit einer Mehrzahl von über den Umfang der Bürstenrolle verteilten Büscheln von Borsten bestückt. Auch bekannt ist der Einsatz von Reinigungswalzen in selbstfahrenden Reinigungsrobotern, welche sich selbsttätig über die zureinigende Fläche bewegen. In der DE 10 2011 014 734 A1 ist ein automatisches Reinigungsgerät zum Reinigen einer Bodenfläche offenbart. Das Reinigungsgerät besitzt eine Reinigungsvorrichtung, welche beispielsweise als Reinigungswalze ausgeführt sein kann.Cleaning devices are known from the prior art, which can be manually pushed over surfaces to be cleaned. Dirt is picked up during the relative movement between the cleaning device and the surface to be cleaned. In the DE 10 2007 061 607 A1 For example, a hand-operated hand cleaning device is described which, among other things, has a driven rotatable brush roller. The brush roller transports dirt into a directly adjacent dirt container. The brush roller is equipped with a plurality of tufts of bristles distributed over the circumference of the brush roller. Also known is the use of cleaning rollers in self-propelled cleaning robots, which move automatically over the surface to be cleaned. In the DE 10 2011 014 734 A1 is an automatic cleaning device disclosed for cleaning a floor surface. The cleaning device has a cleaning device which, for example, can be designed as a cleaning roller.

Im Stand der Technik ist es üblich, derartige Reinigungswalzen als Bürstenwalzen auszuführen, welche im Bereich ihres Außenumfangs mit einem Besatz aus radial nach außen hervorstehenden Büscheln von Borsten versehen sind. Vergleiche z.B. EP 0 653 173 A1 .In the prior art, it is customary to design such cleaning rollers as brush rollers, which are provided in the area of their outer circumference with a set of radially outwardly protruding tufts of bristles. Compare e.g. EP 0 653 173 A1 .

Ist die zu reinigende Oberfläche durch eine Vielzahl von langen Fasern, beispielsweise durch Haare verschmutzt, so besteht das Problem, dass sich die Fasern bei der Rotation der Reinigungswalze um die Reinigungswalze herumwickeln und die Fasern bis zum Fuß der Büschel von Borsten eingezogen werden. Um die Reinigungsleistung der Reinigungseinrichtung aufrecht zu erhalten ist es daher erforderlich, die Fasern in regelmäßigen Abständen aus der Reinigungswalze zu entfernen. Sind diese Fasern jedoch eng um die Reinigungswalze gewickelt und tief die Borstenstrukturen hineingezogen, so ist der Reinigungsprozess der Reinigungswalze sehr umständlich und die Fasern können nur mit sehr großem Aufwand entfernt werden. Aus dem Stand der Technik ist es daher auch bekannt, alternativ zu Bürstenwalzen Reinigungswalzen vorzusehen, welche flexible Flügel aus einem Gummi bzw. Elastomer aufweisen, welche von der Reinigungswalze abragen. Die flexiblen Flügel können dabei z.B. spiralförmig auf einer zentralen Welle angeordnet sein, wie in der DE 39 33 722 A1 offenbart. Eine solche Reinigungswalze kann in regelmäßigen Abständen zwar einfach gereinigt und schnell von langen Fasern, wie insbesondere Haaren, befreit werden, jedoch lässt die Reinigungsleistung der mit den flexiblen Flügeln bestückten Reinigungswalze zu wünschen übrig. Längere Fasern, wie insbesondere Haare, werden von einer solchen Reinigungswalze nicht zuverlässig aufgenommen.If the surface to be cleaned is soiled by a large number of long fibers, for example hair, the problem arises that the fibers wrap around the cleaning roller when the cleaning roller rotates and the fibers are drawn in by bristles up to the foot of the tufts. In order to maintain the cleaning performance of the cleaning device, it is therefore necessary to remove the fibers from the cleaning roller at regular intervals. However, if these fibers are tightly wrapped around the cleaning roller and the bristle structures are drawn in deeply, the cleaning process of the cleaning roller is very laborious and the fibers can only be removed with great effort. It is therefore also known from the prior art to provide cleaning rollers as an alternative to brush rollers, which have flexible wings made of a rubber or elastomer which protrude from the cleaning roller. The flexible wings can, for example, be arranged in a spiral shape on a central shaft, as in FIG DE 39 33 722 A1 disclosed. Such a cleaning roller can be cleaned easily at regular intervals and quickly freed from long fibers, such as hair in particular, but the cleaning performance of the cleaning roller equipped with the flexible wings leaves something to be desired. Longer fibers, such as hair in particular, are not reliably picked up by such a cleaning roller.

Die US 4,177,536 A zeigt eine Reingungswalze gemäß dem Oberbegriff von Anspruch 1. Der Steg ist dabei nicht nachgiebig sondern starr ausgeführt.The U.S. 4,177,536 A shows a cleaning roller according to the preamble of claim 1. The web is not flexible but rigid.

In der US 2015/034230 A1 ist eine Kehrvorrichtung mit einer Reinigungswalze offenbart mit einer Vielzahl von in Reihe angeordneten Büscheln.In the US 2015/034230 A1 discloses a sweeping device with a cleaning roller with a plurality of tufts arranged in a row.

AufgabenstellungTask

Aufgabe der vorliegenden Erfindung ist es daher, eine rotierbare Reinigungswalze zu schaffen, welche im Betrieb eine hohe Reinigungsleistung ermöglicht und in Betriebspausen einfach gesäubert werden kann. Weitere Aufgabe ist es, die rotierbare Reinigungswalze so weiter zu gestalten, dass lange Fasern und insbesondere Haare, wie auch Tierhaare, zuverlässig aufgenommen werden.The object of the present invention is therefore to create a rotatable cleaning roller which enables a high cleaning performance during operation and which can be easily cleaned during breaks in operation. Another task is to further design the rotatable cleaning roller in such a way that long fibers and in particular hair, as well as animal hair, can be reliably picked up.

Technische LösungTechnical solution

Gelöst wird diese Aufgabe durch eine rotierbare Reinigungswalze mit den Merkmalen von Anspruch 1.This object is achieved by a rotatable cleaning roller with the features of claim 1.

Die rotierbare Reinigungswalze besitzt eine zentrale Welle und an der Welle ist in mindestens einer Reihe eine Vielzahl von Borsten angeordnet. Die Borsten sind dabei in Büscheln an der Welle bzw. in der Welle befestigt. Erfindungsgemäß ist jeder Reihe von Büscheln mindestens ein flexibler Steg zugeordnet, wobei der Steg radial hervorstehend an der Welle angebracht ist. Die Befestigung kann dabei formschlüssig oder stoffschlüssig, zum Beispiel durch Vorsehen einer Nut in der Walze oder durch Verkleben ausgeführt sein. Der Steg ist unmittelbar angrenzend an einer Reihe von Büscheln angeordnet und erstreckt sich nur über einen Teil der Höhe der Borsten, derart, dass der Steg die Büschel - insbesondere in ihrem unteren Bereich - von einer Seite kontaktiert und stützt. In anderen Worten: Die Borsten stehen radial über den Steg hervor. Dadurch, dass der Steg an den Büscheln von Borsten anliegt, werden die Borsten in einer Reihe so nebeneinander gedrängt, dass ein durchgehender Borstenstreifen mit einer durchgehenden Kehrlinie entsteht. Damit ist in vorteilhafter Weise sichergestellt, dass Borsten unmittelbar aneinander angrenzen und Schmutzobjekte nicht zwischen Borsten hindurchgelangen können. Somit werden Schmutzobjekte zuverlässig von den Borsten aufgenommen. Weiterhin vorteilhaft ist, dass zwischen dem Fuß der Borsten, d.h. der Stelle, an welcher diese in der zentralen Welle aufgenommen sind, und der Oberkante des flexiblen Stegs keine langen Fasern wie beispielsweise Haare eingezogen werden können. Die länglichen Fasern werden maximal bis zur Oberkante des flexiblen Stegs eingezogen und können somit einfach durch eine Anhebebewegung oder mittels Durchschneiden von der rotierbaren Reinigungswalze entfernt werden. Damit ist eine einfache und schnelle Säuberung der rotierbaren Reinigungswalze in einer Bearbeitungspause möglich.The rotatable cleaning roller has a central shaft and a plurality of bristles are arranged on the shaft in at least one row. The bristles are attached to the shaft or in the shaft in tufts. According to the invention, each row of tufts is assigned at least one flexible web, the web being attached to the shaft in a radially protruding manner. The fastening can be designed with a form fit or material fit, for example by providing a groove in the roller or by gluing. The web is arranged directly adjacent to a row of tufts and extends only over part of the height of the bristles, in such a way that the web holds the tufts - particularly in their lower area - from one side contacted and supports. In other words: the bristles protrude radially from the web. Because the web rests against the tufts of bristles, the bristles are pushed next to one another in a row in such a way that a continuous bristle strip with a continuous sweeping line is created. This advantageously ensures that bristles directly adjoin one another and that dirt objects cannot get through between bristles. This means that dirt objects are reliably picked up by the bristles. It is also advantageous that no long fibers such as hair can be drawn in between the base of the bristles, ie the point at which they are received in the central shaft, and the upper edge of the flexible web. The elongated fibers are drawn in as far as the upper edge of the flexible web and can thus be easily removed from the rotatable cleaning roller by lifting or by cutting. This enables the rotatable cleaning roller to be cleaned quickly and easily during a break in processing.

In vorteilhafter Weiterbildung der erfindungsgemäßen rotierbaren Reinigungswalze ist jeder Reihe von Büscheln ein weiterer flexibler Steg zugeordnet, welcher radial hervorstehend an der zentralen Welle angebracht ist und sich nur über einen Teil der Höhe der Borsten erstreckt, derart, dass die Reihe von Büscheln von beiden Seiten durch je einen flexiblen Steg eingefasst werden. Bei dieser Ausgestaltung der rotierbaren Reinigungswalze werden die Büschel von Borsten besonders gut gestützt, nämlich in ihrem unteren Bereich, behalten in ihrem oberen Bereich jedoch weiterhin eine hohe Flexibilität. Damit wird ein besonders gutes Kehrverhalten erreicht.In an advantageous further development of the rotatable cleaning roller according to the invention, each row of tufts is assigned a further flexible web, which is attached to the central shaft in a radially protruding manner and only extends over part of the height of the bristles, such that the row of tufts from both sides be framed by a flexible bar. In this embodiment of the rotatable cleaning roller, the tufts of bristles are particularly well supported, namely in their lower area, but still retain a high degree of flexibility in their upper area. This achieves particularly good sweeping behavior.

In einer vorteilhaften Ausführungsform der rotierbaren Reinigungswalze sind mindestens zwei Reihen von Büscheln vorgesehen, wobei jeweils zwischen den Reihen von Büscheln eine radial hervorstehende flexible Kehrlippe an der Welle langebracht ist. Die flexible Kehrlippe kann dabei aus einem Elastomer bzw. aus einem Gummi gefertigt sein. Das Vorsehen einer solchen flexiblen Kehrlippe zwischen zwei Reihen von Büscheln trägt in vorteilhafter Weise dazu bei, dass Schmutzpartikel, nämlich längere Fasern, während der Rotation der rotierbaren Reinigungswalze nicht um diese herumgewickelt werden. In Weiterbildung der rotierbaren Reinigungswalze erstreckt sich die mindestens eine Reihe von Büscheln und/oder der mindestens eine Steg im Wesentlichen über die Breite der Walze. Somit entstehen keine Zwischenräume, durch welche Schmutzpartikel passieren könnten.In an advantageous embodiment of the rotatable cleaning roller, at least two rows of tufts are provided, with a radially protruding flexible sweeping lip on the shaft between the rows of tufts is long brought. The flexible sweeping lip can be made of an elastomer or a rubber. The provision of such a flexible sweeping lip between two rows of tufts advantageously contributes to the fact that dirt particles, namely longer fibers, are not wrapped around the rotatable cleaning roller during the rotation thereof. In a further development of the rotatable cleaning roller, the at least one row of tufts and / or the at least one web extends essentially over the width of the roller. This means that there are no gaps through which dirt particles could pass.

Erfindungsgemäß wurde erkannt, dass es vorteilhaft ist, die mindestens eine Reihe von Büscheln, den mindestens einen Steg und gegebenenfalls sofern vorhanden die flexible Kehrlippe spiralförmig auf der Welle anzubringen ähnlich einer Schraubenlinie mit geringer Steigung.According to the invention, it was recognized that it is advantageous to attach the at least one row of tufts, the at least one web and, if applicable, the flexible sweeping lip, if present, to the shaft in a spiral shape, similar to a helical line with a low pitch.

In Weiterbildung dieser Ausführungsvariante kann vorgesehen sein, dass die mindestens eine Reihe von Büscheln und/oder der mindestens eine Steg und/oder sofern vorhanden auch die Kehrlippe über die Breite der Walze zweigeteilt sind und unterschiedliche Steigungen aufweisen, d.h. ähnlich einer Schraubenform ist der erste Teil mit einem Rechtsgewinde und der zweite Teil mit einem Linksgewinde auf der Welle angebracht. Der Vorteil der spiralförmigen Anordnung der Reinigungselemente ist dabei, dass anstelle von nur kurzen Schrubbbewegungen kontinuierliche und effektive Kehrbewegungen durchgeführt werden können.In a further development of this embodiment variant, it can be provided that the at least one row of tufts and / or the at least one web and / or, if present, the sweeping lip are divided into two parts over the width of the roller and have different slopes, ie the first part is similar to a helical shape with a right-hand thread and the second part with a left-hand thread attached to the shaft. The advantage of the spiral arrangement of the cleaning elements is that instead of just short scrubbing movements, continuous and effective sweeping movements can be carried out.

Die Erfindung betrifft auch die Verwendung einer wie oben beschriebenen Reinigungswalze zur Reinigung einer Fläche z.B. eines Fußbodens von Haaren, insbesondere von Tierhaaren.The invention also relates to the use of a cleaning roller as described above for cleaning a surface, for example a floor, from hair, in particular from animal hair.

Weiterhin betrifft die Erfindung eine Kehrvorrichtung, insbesondere einen Reinigungsroboter, mit einer wie oben beschriebenen Reinigungswalze.The invention also relates to a sweeping device, in particular a cleaning robot, with a cleaning roller as described above.

Gegenstand der Erfindung ist auch ein Verfahren zur Herstellung einer wie oben stehend beschriebenen Reinigungswalze mit nachfolgenden Schritten:
In einem ersten Schritt werden Büschel von Borsten in dafür vorgesehene Vertiefungen einer Welle, also eines Walzenkörpers, zur Bildung mindestens einer Reihe von Büscheln eingesetzt und befestigt, z.B. verklebt. In einem zweiten Schritt erfolgt die Befestigung mindestens eines flexiblen Stegs je Reihe von Büscheln an der Welle, wobei der Steg unmittelbar angrenzend an die Reihe von Büscheln angeordnet wird und wobei der Steg die Büschel kontaktiert und stützt. Die Befestigung kann dabei stoffschlüssig und/oder formschlüssig erfolgen. Damit wird ein besonders einfaches Herstellungsverfahren beschrieben, welches auch auf die bekannten Herstellverfahren von Bürsten und Bürstenwalzen anwendbar ist.The invention also relates to a method for producing a cleaning roller as described above with the following steps:
In a first step, tufts of bristles are inserted and fastened, for example glued, into recesses provided for this in a shaft, that is to say a roller body, to form at least one row of tufts. In a second step, at least one flexible web per row of tufts is attached to the shaft, the web being arranged immediately adjacent to the row of tufts and the web contacting and supporting the tufts. The fastening can take place with a material fit and / or a form fit. A particularly simple manufacturing method is thus described which can also be applied to the known manufacturing methods for brushes and brush rollers.

Die beschriebene Erfindung und die beschriebenen vorteilhaften Weiterbildungen der Erfindung stellen auch in Kombination miteinander - soweit dies technisch sinnvoll ist - vorteilhafte Weiterbildungen der Erfindung dar.The described invention and the described advantageous developments of the invention also represent advantageous developments of the invention in combination with one another - insofar as this is technically sensible.

In Figur 1 ist eine rotierbare Reinigungswalze 10 in einer Ansicht und in einem Teilschnitt dargestellt. Die rotierbare Reinigungswalze 10 wird mittels Lagerelementen 9 in einer nicht näher dargestellten Kehrvorrichtung aufgenommen. Um eine Fläche zu reinigen, wird die Reinigungswalze 10 in eine Rotation versetzt. Die rotierbare Reinigungswalze 10 besteht aus einem ersten Walzenteil 7 und einem zweiten Walzenteil 8. Beide Walzenteile 7, 8 erstrecken sich über eine Breite B der Walze 10. Auf der zentralen Welle 1 sind mehrere Borstenstreifen 5 angebracht, welche von Büscheln 2 von einzelnen Borsten 3 gebildet werden. D.h. mehrere Borsten 3 bilden zusammen ein Büschel 2 von Borsten. Jeder Borstenstreifen 5 bildet eine durchgehende Kehrlinie. Dies wird durch flexible Stege 4 erreicht, welche unmittelbar angrenzend an eine Reihe von Büscheln 2 angeordnet sind und an der zentralen Welle 1 angebracht sind. Zusätzlich könnte zwischen den Reihen von Büscheln 2 jeweils eine flexible Kehrlippe 6 an der zentralen Welle 1 angebracht sein. Alle Borstenstreifen 4 der Reihe von Büscheln 2, wie auch die flexiblen Stege 4 und die flexiblen Kehrlippen 6 sind spiralförmig auf der Welle angebracht und weisen in den beiden Walzenteilen 7, 8 unterschiedliche Steigungen auf. In anderen Worten, im ersten Walzenteil 7 sowie im zweiten Walzenteil 8 haben Borstenstreifen 4, flexible Stege 5, flexible Kehrlippen 6 eine verdrillte Form, ähnlich einer Schraubenlinie mit geringer Steigung, wobei die Steigungen im ersten Walzenteil 7 und im zweiten Walzenteil 8 umgekehrt sind.In Figure 1 a rotatable cleaning roller 10 is shown in a view and in a partial section. The rotatable cleaning roller 10 is received by means of bearing elements 9 in a sweeping device not shown in detail. In order to clean a surface, the cleaning roller 10 is set in rotation. The rotatable cleaning roller 10 consists of a first roller part 7 and a second roller part 8. Both roller parts 7, 8 extend over a width B of the roller 10. On the central shaft 1, several bristle strips 5 are attached, which are made of tufts 2 of individual Bristles 3 are formed. That is to say, several bristles 3 together form a tuft 2 of bristles. Each bristle strip 5 forms a continuous sweeping line. This is achieved by flexible webs 4, which are arranged directly adjacent to a row of tufts 2 and are attached to the central shaft 1. In addition, a flexible sweeping lip 6 could be attached to the central shaft 1 between the rows of tufts 2. All the bristle strips 4 of the row of tufts 2, as well as the flexible webs 4 and the flexible sweeping lips 6 are attached in a spiral shape on the shaft and have different gradients in the two roller parts 7, 8. In other words, in the first roller part 7 and in the second roller part 8, bristle strips 4, flexible webs 5, flexible sweeping lips 6 have a twisted shape, similar to a helical line with a slight pitch, the pitches in the first roller part 7 and in the second roller part 8 being reversed.

Alternativ kann die rotierbare Reinigungswalze 10 auch nur ein Walzenteil aufweisen.Alternatively, the rotatable cleaning roller 10 can also have only one roller part.

Alternativ könnten Borstenstreifen 4, flexible Stege 5 und flexible Kehrlippen 6 auch nicht spiralförmig auf der zentralen Welle 1 angebracht sein.Alternatively, bristle strips 4, flexible webs 5 and flexible sweeping lips 6 could also not be attached to the central shaft 1 in a spiral shape.

Die nähere Ausgestaltung der rotierbaren Reinigungswalze 10 ergibt sich durch die Schnittdarstellungen unterschiedlicher Ausführungsformen der Figuren 2a, 2b und 2c. In der in Figur 2a dargestellten Ausführungsvariante der rotierbaren Reinigungswalze 10 sind Borsten 3 an der zentralen Welle 1 befestigt. Die Borsten 3 bilden jeweils Büschel 2 aus, welche in einer Reihe angeordnet sind. Unmittelbar angrenzend an die Reihe von Büscheln 2 ist auf einer Seite ein flexibler Steg 4 angeordnet und an der zentralen Welle 1 angebracht, welcher die Büschel 2 stützt. Der flexible Steg 4 erstreckt sich dabei nur über einen Teil der Höhe der Borsten 3, so dass der Steg 4 die Büschel 2 in ihrem unteren Bereich von einer Seite kontaktiert und stützt. Während in Figur 2a nur eine Reihe von Büscheln 2 an der zentralen Welle 1 angebracht ist, könnten auch mehrere Reihen von Büscheln 2, beispielsweise zwei, drei oder vier an der zentralen Welle angebracht sein.The more detailed configuration of the rotatable cleaning roller 10 results from the sectional views of different embodiments of FIG Figures 2a, 2b and 2c . In the in Figure 2a The illustrated embodiment of the rotatable cleaning roller 10 is bristles 3 attached to the central shaft 1. The bristles 3 each form tufts 2 which are arranged in a row. Immediately adjacent to the row of tufts 2, a flexible web 4 is arranged on one side and attached to the central shaft 1, which supports the tufts 2. The flexible web 4 extends only over part of the height of the bristles 3, so that the web 4, the tufts 2 in their lower Area contacted and supported from one side. While in Figure 2a only one row of tufts 2 is attached to the central shaft 1, several rows of tufts 2, for example two, three or four, could also be attached to the central shaft.

In der Ausführungsvariante von Figur 2b ist die Reihe von Büscheln 2 im Gegensatz zur Ausführungsvariante gemäß Figur 2a von beiden Seiten durch jeweils einen flexiblen Steg 4 abgestützt. Auch hier erstrecken sich die flexiblen Stege 4 nur über einen Teil der Höhe der Borsten 3. Während in der Darstellung von Figur 2b nur eine Reihe von Büscheln 2 an der zentralen Welle 1 angebracht ist, könnten auch mehrere solcher abgestützter Reihen von Büscheln 2 an der Welle 1 angebracht sein.In the variant of Figure 2b is the row of tufts 2 in contrast to the embodiment according to Figure 2a supported on both sides by a flexible web 4 each. Here, too, the flexible webs 4 only extend over part of the height of the bristles 3. While in the illustration of FIG Figure 2b If only one row of tufts 2 is attached to the central shaft 1, several such supported rows of tufts 2 could also be attached to the shaft 1.

In der in Figur 2c dargestellten Ausführungsvariante sind zusätzlich zu den Büscheln 2 auch flexible Kehrlippen 6 vorgesehen, welche ebenfalls an der zentralen Welle 1 befestigt sind. Durch die Kombination der Büschel 2 von Borsten 3 mit flexiblen Kehrlippen 6 kann die Reinigungsleistung der rotierbaren Reinigungswalze 10 verbessert werden. Während in der Darstellung von Figur 2c je zwei Reihen von Büscheln 2 und zwei flexible Kehrlippen 6 vorgesehen sind, können diese auch in unterschiedlicher Anzahl an der zentralen Welle 1 angebracht sein.In the in Figure 2c In addition to the tufts 2, flexible sweeping lips 6 are also provided, which are also attached to the central shaft 1. By combining the tufts 2 of bristles 3 with flexible sweeping lips 6, the cleaning performance of the rotatable cleaning roller 10 can be improved. While in the representation of Figure 2c two rows of tufts 2 and two flexible sweeping lips 6 are provided, these can also be attached to the central shaft 1 in different numbers.

In der Ausführungsvariante gemäß Figur 2d ist die Reihe von Büscheln 2 ebenfalls von einer Seite durch einen flexiblen Steg 4 abgestützt. Der flexible Steg 4 erstreckt sich dabei nur über einen Teil der Höhe der Borsten 3. Neben dem flexiblen Steg 4, welcher die Reihe von Büscheln 2 abstützt, sind zwei weitere, ebenfalls radial ausgerichtete Stege vorgesehen. Alle Stege 4 sind durch ein Element einteilig ausgeformt und können so schnell mit der zentralen Welle 1 verbunden werden. Im oberen Beispiel der Figur 2d wurde das Element der Stege 4 auf die zentrale Welle 1 aufgeklebt. In der darunter dargestellten Ausführung besitzt das Element mit den Stegen 4 eine Feder, welche in eine Nut X in der zentralen Welle 1 eingreifen kann. Nut und Feder sind dabei komplementär ausgestaltet, so dass eine besonders schnelle Montage des Elements mit den Stegen 4 auf der zentralen Welle 1 durch Aufschieben des Elements ermöglicht wird. Während in der Darstellung von Figur 2d nur eine Reihe von Büscheln 2 an der zentralen Welle 1 angebracht ist, können auch mehrere solcher abgestützten Reihen von Büscheln 2 an der Welle 1 angebracht sein.In the variant according to Figure 2d the row of tufts 2 is also supported from one side by a flexible web 4. The flexible web 4 extends only over part of the height of the bristles 3. In addition to the flexible web 4, which supports the row of tufts 2, two further webs, likewise radially oriented, are provided. All webs 4 are formed in one piece by an element and can thus be quickly connected to the central shaft 1. In the above example of the Figure 2d the element of the webs 4 was glued onto the central shaft 1. In the one shown below In the embodiment, the element with the webs 4 has a spring which can engage in a groove X in the central shaft 1. Tongue and groove are designed to be complementary, so that a particularly fast assembly of the element with the webs 4 on the central shaft 1 is made possible by sliding the element. While in the representation of Figure 2d only one row of tufts 2 is attached to the central shaft 1, several such supported rows of tufts 2 can also be attached to the shaft 1.

In der Ausführungsvariante von Figur 2e ist ein ähnliches Element vorgesehen, welches die flexiblen Stege 4 umfasst. Während ein flexibler Steg 4 des Elements eine erste Reihe von Büscheln 2 von der rechten Seite her abstützt, stützt ein weiterer flexibler Steg 4 des Elements eine nächste Reihe von Büscheln 2 von der linken Seite her ab. Wird die zentrale Welle 1 beispielsweise mit vier Reihen von Büscheln 2 versehen, so können vier der dargestellten Elemente mit den flexiblen Stegen 4 auf der zentralen Welle 1 befestigt werden und können so die jeweiligen Reihen von Büscheln 2 beidseitig abstützen.In the variant of Figure 2e a similar element is provided which comprises the flexible webs 4. While a flexible web 4 of the element supports a first row of tufts 2 from the right side, another flexible web 4 of the element supports a next row of tufts 2 from the left. If the central shaft 1 is provided with four rows of tufts 2, for example, four of the elements shown can be fastened to the central shaft 1 with the flexible webs 4 and can thus support the respective rows of tufts 2 on both sides.

Wie bereits anhand der Figur 1 ausgeführt, können die Reihen von Büscheln 2 die flexiblen Stege 4 und gegebenenfalls die flexiblen Kehrlippen 6 spiralförmig auf der Welle angebracht sein. Um eine schnelle und einfache Montage der flexiblen Stege 4 auf der zentralen Welle 1 zu ermöglichen, kann eine sich über die Breite B der Reinigungswalze 10 erstreckende Nut XXX vorgesehen sein, welche ebenfalls spiralförmig auf der zentralen Welle 1 angebracht ist. Eine solche Nut XXX ist in Figur 3a dargestellt. Sollen die flexiblen Stege 4 und gegebenenfalls die flexiblen Kehrlippen 6 nicht spiralförmig auf der Welle 1 angebracht sein, sondern eine gerade Anordnung aufweisen, so kann die zugehörige Nut XXX ebenfalls gerade ausgeführt sein, wie dies in Figur 3b dargestellt ist. Aus den Schnittdarstellungen der Welle 1 an der Position B ergibt sich, dass vier Nuten XXX vorgesehen sind, welche gleichmäßig auf dem Umfang der zentralen Welle 1 verteilt sind. Somit können auch vier flexible Stege 4 oder entsprechend den Figuren 2d und 2e einteilige Elemente, welche flexible Stege 4 aufweisen, mit der zentralen Welle 1 verbunden werden.As already with the Figure 1 executed, the rows of tufts 2, the flexible webs 4 and optionally the flexible sweeping lips 6 can be attached in a spiral shape on the shaft. In order to enable the flexible webs 4 to be mounted quickly and easily on the central shaft 1, a groove XXX extending over the width B of the cleaning roller 10 can be provided, which is also attached in a spiral shape on the central shaft 1. Such a groove XXX is in Figure 3a shown. If the flexible webs 4 and possibly the flexible sweeping lips 6 are not to be attached in a spiral shape on the shaft 1, but rather have a straight arrangement, the associated groove XXX can also be straight, as shown in FIG Figure 3b is shown. From the sectional views of shaft 1 at position B. it results that four grooves XXX are provided, which are evenly distributed over the circumference of the central shaft 1. Thus, four flexible webs 4 or according to the Figures 2d and 2e One-piece elements, which have flexible webs 4, are connected to the central shaft 1.
