The bristles are butt-welded onto the supporting base, with the bristles leaving open a cross section of the opening and forming a duct tapering off toward the bristle ends, which duct leads or supplies the agent into a working area of the device.

Description

Die Erfindung betrifft ein Gerät zum Auftragen fluider Medien mittels Kunststoff-Borsten, die zu Bündeln zusammengefaßt auf einem einen Teil eines das Medium enthaltenden oder führenden Behälters bildenden Kunststoff-Träger festgelegt sind, der mit Öffnungen zum Zuführen des Mediums zu den Borsten versehen ist, wobei die Borsten eines Bündels wenigstens ein Loch im Träger unter Bildung eines das Medium zu ihren Enden führenden Kanals umgeben.The invention relates to a device for applying fluid media by means of plastic bristles, which are combined into bundles and are fixed on a part of a plastic carrier which forms or contains the medium and which is provided with openings for supplying the medium to the bristles, wherein the bristles of a bundle surround at least one hole in the carrier to form a channel leading to the ends of the medium.

Geräte des vorgenannten Aufbaus dienen zum Auftragen von flüssigen und pastenförmigen Medien auf Oberflächen von Gegenständen verschiedener Art. So sind beispielsweise Waschbürsten bekannt (US-PS 2603 805, DE-GM 1 803 125), bei denen das Bürstengehäuse hohl ausgebildet, mit einem Wasseranschluß und - an seinem Boden - mit kanatförmigen Öffnungen versehen ist. Der Boden dient zugleich als Träger für den Borstenbesatz. Im einen Fall (US-PS 2 603 805) weist der Träger, d. h. der Boden der Bürste, zwischen den kanalförmigen Öffnungen Bohrungen auf, in die die Borstenbündel in herkömmlicher Weise eingesetzt sind. Die Bürste wird an eine Wasserleitung angeschlossen, so daß beim Reinigen einer Oberfläche das Wasser zwischen den Borstenbündeln austritt und die Oberfläche benetzt. Es wird also mit der Reinigungsbewegung zugleich das Reinigungsmedium aufgetragen. Durch die rasterförmige Anordnung von Öffnungen einerseits und Borstenbündeln andererseits findet eine gute Verteilung des Wassers statt. Im anderen bekannten Fall (DE-GM 1 803 125) ist jedes Borstenbündel an seinem einen Ende mit einem Kunststoff-Kopf versehen, der in eine Öffnung am Boden des Bürstengehäuses eingesteckt werden kann und dort verrastet. Der Kopf ist mit einem zentrischen Kanal versehen, durch den die Flüssigkeit aus dem Bürstengehäuse in das Borstenbündel austreten kann. Die Borsten sollen mit dem Kopf durch einen Polymerisationsvorgang verbunden werden. Dies allerdings ist technisch nicht durchführbar .-Während es bei Waschbürsten nicht darauf ankommt, daß das Reinigungswasser in kleinen dosierten Mengen abgegeben wird, ist es beispielsweise bei Pinseln zum Auftragen von Farben oder Pasten erwünscht, daß das Medium in nur relativ kleinen Mengen entsprechend dem Bedarf beim Auftragen auf eine Oberfläche abgegeben wird. Um dies zu erreichen, sind im Träger entweder (DE-OS 28 41 264) an dem Borstenträger mehrere Öffnungen angeordnet, in denen jeweils ein Borstenbündel in herkömmlicher Weise eingekittet wird, oder aber (DE-PS 646 288) bildet der Borstenträger des Pinsels den Deckel eines Behälters, der mit einer zentralen Bohrung zur Abgabe des im Behälter enthaltenen Mediums an die Borsten versehen ist. In diesem Fall ist zwischen Behälter und Deckel ein Ventil zur Einstellung der überströmenden Menge angeordnet. Auch hier sind die Borsten in herkömmlicher Weise in den napfförmig ausgebildeten Träger eingekittet. Im erstgenannten Fall werden in die Öffnungen des Trägers Kapillarröhren eingesetzt, die bis nahe an die Borstenenden heranreichen und durch die das Medium aus dem Gerätebehälter in jeweils ein Borstenbündel gelangt. Eine dosierte Abgabe des Mediums ist dabei jedoch nicht möglich, da die Borsten in Parallellage angeordnet sind und das Medium infolgedessen annähernd widerstandslos das Borstenbündel durchdringen kann. Hinzu kommt, daß die eingesetzten Kapillarröhren im allgemeinen steifer sind als das Material der Borsten mit dem Ergebnis, daß das Auftragen beeinträchtigt wird.Devices of the aforementioned construction are used for applying liquid and pasty media to surfaces of objects of various types. For example, washing brushes are known (US Pat. No. 2603 805, DE-GM 1 803 125) in which the brush housing is hollow, with a water connection and - at its bottom - is provided with channel-shaped openings. The bottom also serves as a support for the bristle trim. In one case (US Pat. No. 2,603,805), the carrier, ie the bottom of the brush, has bores between the channel-shaped openings, into which the bristle bundles are inserted in a conventional manner. The brush is connected to a water pipe, so that when cleaning a Surface water emerges between the bristle bundles and wets the surface. The cleaning medium is thus applied at the same time as the cleaning movement. Due to the grid-like arrangement of openings on the one hand and bristle bundles on the other hand, the water is distributed well. In the other known case (DE-GM 1 803 125), each bristle bundle is provided at one end with a plastic head, which can be inserted into an opening in the bottom of the brush housing and locked there. The head is provided with a central channel through which the liquid can escape from the brush housing into the bristle bundle. The bristles are said to be connected to the head by a polymerization process. However, this is not technically feasible. While washing brushes do not depend on the fact that the cleaning water is dispensed in small doses, it is desirable, for example, for brushes for applying paints or pastes that the medium is only available in relatively small amounts as required is released when applied to a surface. To achieve this, multiple openings are arranged in the carrier either (DE-OS 28 41 264) on the bristle carrier, in each of which a bundle of bristles is cemented in a conventional manner, or (DE-PS 646 288) the bristle carrier of the brush forms the Lid of a container, which is provided with a central bore for dispensing the medium contained in the container to the bristles. In this case, a valve for adjusting the overflowing quantity is arranged between the container and the lid. Here too, the bristles are cemented in the cup-shaped carrier in a conventional manner. In the former case, capillary tubes are inserted into the openings of the carrier, which reach close to the bristle ends and through which the medium reaches a bundle of bristles from the device container. A metered delivery of the medium is not possible, however, since the bristles are arranged in a parallel position and the medium as a result can penetrate the bristle bundle almost without resistance. In addition, the capillary tubes used are generally stiffer than the material of the bristles, with the result that the application is impaired.

Mit Ausnahme der beschriebenen Waschbürsten konnten sich die vorgenannten Geräte in der Praxis nicht durchsetzen, da einerseits die Fertigungstechnik viel zu aufwendig, andererseits die Abgabe kleiner und dosierter Mengen, wie sie beim Auftragen von Medien gefordert wird, nicht möglich ist. Der Erfindung liegt deshalb die Aufgabe zugrunde , das eingangs geschilderte Gerät so auszubilden, daß es sich einerseits fertigungstechnisch ohne größere Schwierigkeiten realisieren läßt, andererseits das dosierte Auftragen auch kleiner Mengen fluider Medien gestattet, ohne daß hierfür gesonderte Dosiereinrichtungen oder dgl. notwendig sind.With the exception of the washing brushes described, the above-mentioned devices could not prevail in practice, since on the one hand the manufacturing technology is far too complex, and on the other hand it is not possible to dispense small and metered quantities, as is required when applying media. The invention is therefore based on the object of designing the device described at the outset in such a way that, on the one hand, it can be implemented without major difficulties in terms of production technology, and on the other hand allows the metered application of even small amounts of fluid media without the need for separate metering devices or the like.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kunststoff-Träger für die Borsten dünnwandig ausgebildet ist und die Borsten des Bündels unter Freilassen der Öffnung auf den Träger stumpf aufgeschweißt sind.This object is achieved in that the plastic carrier for the bristles is thin-walled and the bristles of the bundle are butt welded to the carrier while leaving the opening.

Bei der erfindungsgemäßen Ausbildung müssen Träger und Borsten naturgemäß aus solchen Kunststoffen bestehen, die miteinander verschweißbar sind. Solche Werkstoffe, z. B. Nylon, Polyäthylen, Polypropylen etc., sind bekannt. Der Träger soll erfindungsgemäß dünnwandig ausgebildet sein, damit der Wärmeübergang beim Schweißvorgang sowohl an den Borstenenden, als auch an dem Träger etwa gleich gut ist und somit das Anschmelzen beider Bereiche gleichmäßig und gleichzeitig erfolgt. Durch das stumpfe Aufschweißen der Borstenbündel einerseits und das gleichzeitige Freilassen der Öffnung an dem Träger können die Borsten jedes Bündels in einer solchen Lage angebracht werden, daß sich zumindest die inneren Borsten, stark nach innen neigen und aufgrund ihrer Biegsamkeit dicht aneinander liegen. Dadurch wird ein sich von der Öffnung zu den Borstenenden hin verjüngender Kanal gebildet, der durch die dichte Anlage der Borsten im Bereich der Borstenenden eine Art Verschluß aufweist. Das Medium, das in einem Behälter enthalten oder von diesem geführt ist, kann nur dann austreten, wenn der durch die dicht liegenden Borsten vorhandene Widerstand aufgehoben wird, so daß sich der verjüngende Kanal öffnet. Dies kann dadurch geschehen, daß beispielsweise der Behälter aus einem defomierbaren und sich wieder rückstellenden Werkstoff besteht, so daß das in ihm enthaltene Medium durch Zusammendrücken des Behälters unter geringen Überdruck gesetzt werden kann. Das Medium tritt dann durch die Öffnungen im Träger, der einen Teil des Behälters bildet, in die sich verjüngenden Kanäle aus, wobei die Borsten unter der Wirkung des Überdrucks ausweichen und das Medium austreten kann. Der gleiche Effekt läßt sich auch durch das Auftragen selbst erreichen, indem beim Bestreichen der zu behandelnden Oberfläche die Borsten in bekannter Weise abgebogen und ausgebreitet werden, so daß sich die Kanäle öffnen bzw. der dort vorhandene Widerstand verringert wird und das Medium austreten kann.In the configuration according to the invention, the carrier and bristles must naturally consist of plastics which can be welded to one another. Such materials, e.g. B. nylon, polyethylene, polypropylene, etc. are known. According to the invention, the carrier should be thin-walled so that the heat transfer during the welding process is approximately the same both at the bristle ends and on the carrier, and thus the melting of both areas takes place uniformly and simultaneously. Due to the butt welding of the bristle bundles on the one hand and the simultaneous uncovering of the opening on the carrier, the bristles of each bundle can be attached in such a position that at least the inner bristles become heavily backward incline inside and, due to their flexibility, lie close together. This forms a channel which tapers from the opening to the bristle ends and which has a type of closure due to the tight contact of the bristles in the region of the bristle ends. The medium contained in or guided by a container can only escape if the resistance provided by the close-lying bristles is removed, so that the tapering channel opens. This can be done in that, for example, the container consists of a deformable and resettable material, so that the medium contained in it can be put under slight excess pressure by compressing the container. The medium then exits through the openings in the carrier, which forms part of the container, into the tapered channels, the bristles evading under the effect of the excess pressure and the medium being able to escape. The same effect can also be achieved by the application itself, in that the bristles are bent and spread out in a known manner when the surface to be treated is coated, so that the channels open or the resistance present there is reduced and the medium can escape.

Dabei läßt sich auch die Länge der Kanäle anläßlich des stumpfen Aufschweißens der Borsten auf den Träger in Grenzen vorbestimmen, indem die Borsten beispielsweise in unterschiedlichem Abstand von den freien Enden während des Schweißvorgangs eng umfaßt werden, wodurch sich der Neigungswinkel vor allem der innen liegenden Borsten variieren läßt. Kürzere Kanäle wird man vor allem bei Medien geringer, lange Kanäle bei Medien größerer Viskosität vorsehen - Im übrigen dienen dann diese Kanäle als Vorratskammern, so daß das Medium sofort bei Verwendung des Gerätes zur Abgabe bereitsteht.The length of the channels during the butt welding of the bristles onto the carrier can also be predetermined within limits, for example by closely enclosing the bristles at different distances from the free ends during the welding process, as a result of which the angle of inclination, especially of the bristles on the inside, varies leaves. Shorter channels will be provided especially for media with a lower volume, long channels for media with a higher viscosity - otherwise these channels then serve as storage chambers, so that the medium is immediately available for dispensing when the device is used.

Praktische Versuche haben gezeigt, daß sich mit einem erfindungsgemäß ausgebildeten Gerät Medien unterschiedlicher Art, z. B. Putz und Reinigungspasten, Waschmittel konzentrate, Pflegemittel für Metalloberflächen, Haarfärbemittel und -festiger, Gußverzierungen für Konditorwaren, thixotrope Flüssigkeiten, wie Holzschutzmittel etc., auftragen lassen.Practical tests have shown that media of different types, eg. B. plaster and cleaning pastes, detergent concentrates, care products for metal surfaces, hair dyes and setting agents, cast decorations for confectionery, thixotropic liquids such as wood preservatives etc., can be applied.

Gemäß einem Ausführungsbeispiel der Erfindung sind die Borsten je eines Bündels mit Abstand vom Rand der Öffnung angeordnet. Dadurch läßt sich der Neigungswinkel der inneren Borsten und damit der Kraftschluß im Bereich der Borstenenden weiter vergrößern bzw. der Verschluß des von ihnen gebildeten Kanals verstärken.According to an embodiment of the invention, the bristles of a bundle are arranged at a distance from the edge of the opening. As a result, the angle of inclination of the inner bristles and thus the frictional connection in the region of the bristle ends can be further increased or the closure of the channel formed by them can be strengthened.

Gemäß einem weiteren Ausführungsbeispiel umgeben die Borsten eines Bündels zugleich mehrere Öffnungen im Träger unter Bildung nur eines Kanals. Mit dieser Ausbildung kann die Menge des über einen Kanal abzugebenden Mediums erhöht werden. Zugleich wird aber durch die Vielzahl kleinerer Öffnungen erreicht, daß auch diese größere Menge gedrosselt in den Borstenkanal überströmt und keine zu große und zu schnelle Medienabgabe erfolgt. Der dünnwandige Träger der Borsten kann unmittelbar als Decke eines Behälters oder als Teil desselben ausgebildet sein, wobei der Behälter vorzugsweise kollebierbar ist.According to a further exemplary embodiment, the bristles of a bundle simultaneously surround a plurality of openings in the carrier, forming only one channel. With this design, the amount of the medium to be dispensed via a channel can be increased. At the same time, however, the large number of smaller openings means that this larger quantity also flows throttled into the bristle channel and that the media is not discharged too quickly and too quickly. The thin-walled carrier of the bristles can be formed directly as a ceiling of a container or as part of the same, the container preferably being collectable.

Das stumpfe Aufschweißen der Borsten auf den dünnwandigen Träger eröffnet weiterhin die Möglichkeit, daß die Öffnungen im Träger nicht unbedingt Kreisrund sein müssen, sondern oval , eckig, schlitz- oder stammartig ausgebildet sein können. Dadurch ergibt sich eine weitere Möglichkeit der Drosselung des Mediums bzw. der dosierten Zuführung desselben zu den Borsten. Solche Querschnittsformen sind beim herkömmlichen Einkitten, Einkleben oder dgl. der Borsten nicht möglich. Die erfindungsgemäße Anbringung der Borsten gestattet es ferner, daß jedes Borstenbündel aus einer Mischung verschiedenartiger Borsten besteht, beispielsweise können runde Borsten verschiedener Durchmesser innerhalb eines Borstenbündels eingesetzt werden, wodurch eine besonders gute Dichtwirkung am Borstenende erreicht wird. Es können aber auch Borsten dreieckigen oder ovalen Querschnittes eingesetzt werden, um beispielsweise unterschiedliche Kapiltarwirkungen innerhalb eines Bündels zu erreichen. Ebenso ist es möglich, jedes Bündel oder ein Teil der Bündel in eckiger Umrißform anzubringen, was sich bei der herkömmlichen Fertigungstechnik nicht realisieren läßt.The butt welding of the bristles onto the thin-walled carrier further opens up the possibility that the openings in the carrier do not necessarily have to be circular, but can be oval, angular, slot-like or stem-like. This results in a further possibility of throttling the medium or metering the same to the bristles. Such cross-sectional shapes are not possible with conventional cementing, gluing or the like of the bristles. The attachment of the bristles according to the invention also allows each bristle bundle to consist of a mixture of different types of bristles, for example round bristles of different diameters can be used within a bristle bundle, as a result of which a particularly good sealing effect is achieved at the bristle end. However, bristles with a triangular or oval cross section can also be used, for example in order to achieve different capillary effects within a bundle. It is also possible to attach each bundle or part of the bundle in an angular outline, which cannot be achieved with conventional manufacturing technology.

Gemäß einer weiteren Ausführungsform ist der dünnwandige Träger biegsam ausgebildet. Diese Ausführungsform ist insbesondere für borstenartige Geräte von Bedeutung, indem der Träger in der Ausgangsform so gewölbt ist, daß die Borstenbündel das Medium zangenartig festhalten, während durch leichtes Biegen des Trägers der Kraftschluß zwischen den Borsten verringert und das Medium abgegeben wird. Es hat sich gezeigt, daß auf diese Weise sogar pulverförmige Reinigungsmittel in dosierter Form aufgetragen werden können. Aufgrund des dichten Abschlusses der das Medium führenden Kanäle ist es weiterhin möglich, daß ein Teil der von den Borstenbündeln gebildeten Kanäle an eine Einrichtung zur Rückführung des im Arbeitsbereich nicht gebundenen, überschüssigen Mediums angeschlossen ist. So kann beispielsweise das Medium durch den einen Teil der Borstenbündel unter leichtem Überdruck austreten, während es über den anderen Teil der Borstenbündel durch Saugwirkung aufgenommen wird. Die abgebenden und die aufnehmenden Borstenbündel können in hintereinander liegenden Reihen angeordnet sein, wobei die aufnehmenden Borstenbündel in einer in Arbeitsrichtung nachlaufenden Reihe vorgesehen sind.According to a further embodiment, the thin-walled carrier is designed to be flexible. This embodiment is particularly important for bristle-like devices, in that the carrier is arched in the initial form in such a way that the bristle bundles hold the medium in the manner of pliers, while by slightly bending the carrier the adhesion between the bristles is reduced and the medium is released. It has been shown that even powdered cleaning agents can be applied in a metered form in this way. Due to the tight closure of the channels carrying the medium, it is also possible for some of the channels formed by the bristle bundles to be connected to a device for returning the excess medium which is not bound in the working area. For example, the medium can escape through one part of the bristle bundle under a slight overpressure, while it is absorbed by the other part of the bristle bundle by suction. The emitting and the receiving bristle bundles can be arranged in rows one behind the other, the receiving bristle bundles being provided in a row following in the working direction.

Die Erfindung betrifft ferner ein Verfahren zur Herstellung der vorgenannten Geräte, das darin besteht, daß die Borsten eines Bündels an ihrem dem dünnwandigen Träger zugekehrten Ende vom Zentrum des Bündels ausgehend nach außen verdrängt werden, bis der im Zentrum des Bündels entstehende, von Borsten freie Querschnitt zumindest dem lichten Querschnitt einer Öffnung im Träger entspricht, und daß die Borsten zugleich oder anschließend auf dem Träger stumpf aufgeschweißt werden.The invention further relates to a method for producing the aforementioned devices, which consists in that the bristles of a bundle at their end facing the thin-walled carrier are displaced outwards from the center of the bundle until the cross-section free of bristles which arises in the center of the bundle corresponds at least to the clear cross section of an opening in the carrier, and that the bristles are butt-welded at the same time or subsequently on the carrier.

Durch dieses Verfahren wird erreicht, daß die Borsten im wurzelnahen Bereich dicht gepreßt werden, so daß das in den von den Borsten gebildeten Kanal eindringende Medium nicht seitlich durch die Borsten austreten kann sondern zwangsläufig zu den Borstenenden geführt wird. Ferner erhalten dadurch die Borsten eine Neigung nach innen, so daß sie sich zu den Borstenenden hin biegsam aneinander legen und einen Kanalverschluß bilden. Das stumpfe Aufschweissen erfolgt vorzugsweise im soqenanntei Heizspiegelverfahren, bei welchem zwischen den Borstenenden und dem dünnwandigen Träger eine Heizplatte angeordnet wird, die Borsten und der Träger von gegenüberliegenden Seiten an die Heizplatte herangefahren und gleichzeitig in einer dünnen Schicht aufgeschmolzen werden. Die Heizplatte wird dann herausgezogen und die Borstenbündel und der Träger zusammengedrückt, bis der Kunststoff erhärtet und eine feste Verbindung hergestellt ist. Das Verdrängen der Borsten im Zentrum kann durch entsprechende Verdrängungskörper geschehen, die an der Heizplatte oder in anderer Weise angeordnet sind.This method ensures that the bristles in the area close to the roots are pressed tightly, so that the medium penetrating into the channel formed by the bristles cannot escape laterally through the bristles but is inevitably guided to the bristle ends. In addition, this gives the bristles an inward incline so that they lie flexibly against one another towards the bristle ends and form a channel closure. The butt welding is preferably carried out in the so-called heating mirror method, in which a heating plate is arranged between the bristle ends and the thin-walled carrier, the bristles and the carrier are brought up to the heating plate from opposite sides and are simultaneously melted in a thin layer. The heating plate is then pulled out and the bristle bundles and the carrier are pressed together until the plastic has hardened and a firm connection has been established. The bristles in the center can be displaced by appropriate displacement bodies which are arranged on the heating plate or in some other way.

Während des Verdrängens der Borsten im Zentrum der Bündel wird das Bündel unter Beibehaltung seiner Umrißform außenseitig gefaßt um ein Ausweichen der Borsten zu verhindern.During the displacement of the bristles in the center of the bundle, the bundle is gripped on the outside while maintaining its outline shape in order to prevent the bristles from escaping.

Schließlich ist es möglich, die Öffnungen im Träger anläßlich des Verschweißens der Borsten mit dem Träger auszuformen, indem beispielsweise beheizte Stifte in den Träger eingedrückt werden. Diese können an der Heizplatte selbst angeordnet sein.Finally, it is possible to shape the openings in the carrier when the bristles are welded to the carrier, for example by pressing heated pins into the carrier. These can be arranged on the heating plate itself.

Die Kappe 3 ist über ein Gewinde 4 mit dem Vorratsbehälter 6 verschraubt. Die Öffnungen 2 des Trägers 5 sind je für sich von den Borsten 1 eines Borstenbündels 10, 11, 12 umgeben, so daß innerhalb jedes Borstenbündels ein Kanal 13 gebildet wird, der sich in Richtung der Borstenenden verengt und dort durch die Borsten 1 direkt verschlossen ist. Die Öffnungen 2 in dem Träger 5 finden ihre Fortsetzung in entsprechenden Öffnungen im oberen Te i der Kappe 3, so daß insgesamt Kariäl e für den Durchtritt des Mediums gebildet werden.The devices shown in FIGS. 1 and 2 each consist of a storage container 6 with a cap 3, the upper side of which carries a carrier 5 with openings 2 and bristles 1. The cap 3 is screwed to the reservoir 6 via a thread 4. The openings 2 of the carrier 5 are each surrounded by the bristles 1 of a bristle bundle 10, 11, 12, so that a channel 13 is formed within each bristle bundle, which narrows in the direction of the bristle ends and is closed there directly by the bristles 1 . The openings 2 in the carrier 5 are continued in corresponding openings in the upper part of the cap 3, so that a total of caries are formed for the passage of the medium.

Jedes Bündel 10, 11, 12 ist stumpf auf den Träger 5 aufgeschweißt, der seinerseits von einer dünnen Kunststoffscheibe gebildet ist. Nach dem Aufschweißen der Borsten 1 wird der Träger 5 an der Kappe 3 des Behälters 6 befestigt, z.B. eingeschweißt, geklebt od.dgl..Each bundle 10, 11, 12 is butt-welded onto the carrier 5, which in turn is formed by a thin plastic disc. After welding the bristles 1, the carrier 5 is attached to the cap 3 of the container 6, e.g. welded, glued or the like ..

Figur 3 zeigt eine vergrößerte Detailansicht der Schraubkappe 3.FIG. 3 shows an enlarged detailed view of the screw cap 3.

Statt der Anordnung je eines Borstenbündels 10, 11, 12 um den Offnungsrand jedes Lochs 2, kann auch ein einziges Borstenbündel entsprechend größeren Außendurchmessers eingesetzt werden, das dann entsprechend der Anzahl der Löcher mehrere Kanäle für den Durchfluß des Mediums aufweist.Instead of arranging a bundle of bristles 10, 11, 12 around the opening edge of each hole 2, a single bundle of bristles corresponding to a larger outside diameter can also be used, which then has several channels for the flow of the medium according to the number of holes.

Fig. 4 und 5 zeigen Draufsicht und Seitenansicht eines Teils einer Waschbürste 14.
