Abstract

Apparatuses for applying liquids have plastic bristles which are grouped into bundles and are fixed to a plastic bristle bearer by a thermal melt connection in such a way that, within the bundle, at least one channel is formed which tapers towards the bristle ends and extends an exit opening, arranged in the bristle bearer, for the medium into the region of the bristle ends. Such apparatuses are produced simply and cost-effectively due to the fact that a riser tube, adjoining the exit opening and projecting into the channel in the bristle bundle, is produced by thermal melting and shaping of the bristles and/or the bristle bearer.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Geräten zum Auftragen fluider Medien mittels Borsten aus Kunststoff, die zu Bündeln zusammengefaßt auf einem Bor­stenträger aus Kunststoff durch eine thermische Schmelz­verbindung derart festgelegt sind, daß innerhalb des Bündels mindestens ein sich zu den Borstenenden verjüngender Kanal gebildet wird, der eine im Borstenträger angeordnete Aus­trittsöffnung für das Medium bis in den Bereich der Bor­stenenden verlängert. Ferner bezieht sich die Erfindung auf eine zur Durchführung des Verfahrens geeignete Vorrichtung.The invention relates to a method for producing devices for applying fluid media by means of plastic bristles, which are arranged in bundles on a bristle carrier made of plastic by means of a thermal fusion connection such that at least one channel tapering towards the bristle ends is formed within the bundle. which extends an outlet opening arranged in the bristle carrier for the medium into the region of the bristle ends. Furthermore, the invention relates to a device suitable for carrying out the method.

Geräte zum Auftragen fluider Medien, wie Flüssigkeiten, Pasten, Pulver od. dgl., sind in einer Vielzahl von Aus­führungsformen bekannt. Die Erfindung befaßt sich nur mit solchen Geräten, bei denen im Borstenträger wenigstens eine Öffnung vorhanden ist, durch die das fluide Medium unmittelbar in das Borstenbündel austreten kann. Zum Trans­port des Mediums zu den Borstenenden bilden die Borsten einen von der Austrittsöffnung zu den Borstenenden reichen­den und sich in dieser Richtung verjüngenden Kanal. Durch konisches Anstellen der Borsten liegen diese an ihrem nutzungsseitigen Ende dicht aneinander und schließen somit den Kanal gegen ungewolltes Ausfließen des Mediums ab.Devices for applying fluid media, such as liquids, pastes, powders or the like, are known in a large number of embodiments. The invention is concerned only with devices in which there is at least one opening in the bristle carrier through which the fluid medium can exit directly into the bristle bundle. The bristles form to transport the medium to the bristle ends a channel extending from the outlet opening to the bristle ends and tapering in this direction. Due to the conical positioning of the bristles, they lie close together at their end on the use side and thus close off the channel against undesired outflow of the medium.

Bei einer bekannten Ausführungsform (DE-OS 32 42 757) sind die aus Kunststoff bestehenden Borsten an einer dünnen Kunststoffscheibe als Borstenträger durch thermisches Schmelzen, z. B. durch Schweißen, befestigt. Die Scheibe weist die für den Mediendurchtritt notwendigen Öffnungen auf. Diese Öffnungen fluchten mit entsprechenden Öffnungen an einem Verschluß für den das Medium enthaltenden Behälter. Der scheibenförmige Borstenträger mit den Borsten ist in den Verschluß eingesetzt.In a known embodiment (DE-OS 32 42 757), the bristles made of plastic are on a thin plastic disc as a bristle carrier by thermal melting, for. B. fixed by welding. The disc has the openings necessary for the media to pass through. These openings are aligned with corresponding openings on a closure for the container containing the medium. The disk-shaped bristle carrier with the bristles is inserted into the closure.

Die Herstellung eines derartigen Gerätes ist nur in mehreren Arbeitsgängen möglich und daher außerordentlich kostenauf­wendig. Es kommt hinzu, daß die Befestigung der Borsten an dem dünnen scheibenförmigen Borstenträger nicht immer zuverlässig ist und daß vor allem aufgrund der Art der Befestigung durch Schweißen der Borstenschluß am Ende des medienführenden Kanals nicht mit gleichbleibender Qualität gewährleistet ist, so daß das Medium insbesondere beim Andrücken der Borsten an die Auftragsfläche seitlich aus­treten kann.The manufacture of such a device is only possible in several operations and is therefore extremely costly. In addition, the attachment of the bristles to the thin, disc-shaped bristle carrier is not always reliable and, above all, due to the type of attachment by welding, the bristle closure at the end of the media-guiding channel is not guaranteed to be of a constant quality, so that the medium, in particular when pressed the bristles can emerge from the side of the application area.

Bei einer anderen bekannten Ausführung in Form eines Rasier­pinsels (DE-OS 36 16 148) ist der Stiel als Behälter für Flüssigseife ausgebildet, auf den der Pinselkopf als Ver­schluß aufgesetzt ist. Der Pinselkopf weist zu diesem Zweck einen Borstenträger in Form einer Schraubkappe mit einer zentralen Öffnung und einem daran einstückig anschließenden Steigrohr auf, das im Zentrum des Borstenbündels ausmündet. Hier fehlt es an einem Kanal im Borstenbündel und an einem Borstenschluß im Bereich der Borstenenden, so daß das Medium zur Seite hin austreten und nicht gezielt aufgetragen werden kann. In einer anderen Ausführung ist die die Borsten tragende Schraubkappe lediglich mit einer zentralen Öffnung versehen, während das Steigrohr den oberen Abschluß des Behälters bildet und beim Aufschrauben des Pinselkopfs in das Borstenbündel eindringt. Zu diesem Zweck sind die Bor­sten im Zentrum ausgespart. Hier gelten jedoch in funk­tioneller Hinsicht die gleichen Nachteile wie bei der zuvor beschriebenen Ausführung.In another known embodiment in the form of a shaving brush (DE-OS 36 16 148) the handle is designed as a container for liquid soap, on which the brush head is placed as a closure. For this purpose, the brush head has a bristle holder in the form of a screw cap with a central opening and a riser pipe connected in one piece, which opens out in the center of the bristle bundle. There is one channel in the bristle bundle and one missing Bristle closure in the area of the bristle ends so that the medium escapes to the side and cannot be applied in a targeted manner. In another embodiment, the screw cap carrying the bristles is only provided with a central opening, while the riser pipe forms the upper end of the container and penetrates into the bristle bundle when the brush head is screwed on. For this purpose, the bristles are left out in the center. From a functional point of view, however, the same disadvantages apply here as in the previously described embodiment.

Alle bekannten Ausführungsformen haben zudem den Nachteil, daß es fertigungstechnisch sehr schwierig ist, die Borsten eines Bündels um eine Öffnung herum zu positionieren und in dieser Stellung zuverlässig zu befestigen.All known embodiments also have the disadvantage that it is very difficult in terms of production technology to position the bristles of a bundle around an opening and to reliably fasten them in this position.

Der Erfindung liegt die Aufgabe zugrunde, das eingangs genannte Verfahren dahingehend weiterzuentwickeln, daß eine Herstellung des Gerätes in nicht mehr als zwei Arbeits­stufen möglich ist und ein sicherer Halt der Borsten einer­seits sowie ein zuverlässiger Borstenschluß am Ende des Kanals andererseits gewährleistet ist.The invention has for its object to further develop the method mentioned in such a way that the device can be manufactured in no more than two working stages and a secure hold of the bristles on the one hand and a reliable bristle closure at the end of the channel on the other hand is ensured.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein an die Austrittsöffnung anschließendes und in den Kanal im Borstenbündel hineinragendes Steigrohr durch thermisches Aufschmelzen und Umformen der Borsten und/oder des Borsten­trägers erzeugt wird.According to the invention, this object is achieved in that a riser tube which adjoins the outlet opening and projects into the channel in the bristle bundle is produced by thermal melting and reshaping of the bristles and / or the bristle carrier.

Es ist zwar bekannt (z. B. US-PS 3 798 699), Borsten an ihrem befestigungsseitigen Ende aufzuschmelzen und die Schmelze zu einem plattenförmigen Ansatz od. dgl. umzu­formen, so daß eine Art Borstenträger entsteht, mittels dessen das Borstenbündel an einem weiteren Träger befestigt werden kann. Bei diesen Borstenträgern sind jedoch weder Austrittsöffnungen für Medien, noch Steigrohre vorhanden, wie dies bei dem eingangs genannten Stand der Technik der Fall ist. Die Erfindung besteht demgegenüber darin, aus dem Kunststoffmaterial der Borsten oder des Borstenträgers, an dem die Borsten zuvor durch thermische Schmelzvorgänge befestigt worden sind, gegebenenfalls auch aus beiden Materialien, durch Aufschmelzen und Umformen ein Steigrohr auszubilden. Bei diesem Umformen wird die Schmelze bzw. die plastischverformbare Masse in das Borstenbündel hinein verdrängt, und zwar entweder in dem durch entsprechende Anstellung der Borsten bereits vorhandenen Kanal oder aber wird der Kanal anläßlich dieses Verdrängungsprozesses inner­halb des Borstenbündels erst erzeugt. Dadurch, daß die Borsten entweder zuvor am Borstenträger durch thermische Verfahren befestigt worden sind oder aber die Ausbildung von Borstenträger und Steigrohr anläßlich des Aufschmelzens des Borstenmaterials erfolgt und somit ein gesonderter Befestigungsvorgang entfällt, lassen sich Geräte der ge­nannten Art in stets reproduzierbar gleicher Qualität her­stellen, insbesondere ein gleichbleibend guter Borsten­schluß an den nutzungsseitigen Enden der Borsten erreichen. Im übrigen wird die Herstellung insgesamt erheblich verein­facht, weil dann, wenn Borstenträger und Steigrohr aus dem Borstenmaterial selbst erzeugt werden, nur ein einziger Arbeitsgang notwendig ist, in dem anderen Fall, daß die Borsten zunächst an einem Borstenträger befestigt und dann dieser umgeformt wird, maximal zwei Arbeitsgänge erforder­lich sind.It is known (e.g. US Pat. No. 3,798,699) to melt bristles at their attachment-side end and to shape the melt into a plate-shaped extension or the like, so that a type of bristle carrier is created by means of which the bundle of bristles is attached to another Carrier can be attached. With these bristle carriers, however, are neither Outlet openings for media, risers still available, as is the case with the prior art mentioned at the beginning. In contrast, the invention consists in forming a riser pipe from the plastic material of the bristles or the bristle carrier, to which the bristles have previously been attached by thermal melting processes, and optionally also from both materials, by melting and reshaping. During this reshaping, the melt or the plastically deformable mass is displaced into the bristle bundle, either in the channel already provided by appropriate adjustment of the bristles, or the channel is only created within the bristle bundle on the basis of this displacement process. The fact that the bristles have either been previously attached to the bristle carrier by thermal methods or that the bristle carrier and riser tube are formed when the bristle material melts and a separate fastening process is thus omitted, devices of the type mentioned can always be reproducibly of the same quality, in particular achieve a consistently good bristle seal at the ends of the bristles on the usage side. Incidentally, the overall production is considerably simplified, because if the bristle carrier and riser tube are produced from the bristle material itself, only a single operation is necessary, in the other case that the bristles are first attached to a bristle carrier and then this is formed, to a maximum two operations are required.

In bevorzugter Ausführung ist vorgesehen, daß die befesti­gungsseitigen Enden der Borsten aufgeschmolzen werden und die Schmelze zu dem Borstenträger mit Austrittsöffnung und Steigrohr umgeformt wird.In a preferred embodiment it is provided that the attachment-side ends of the bristles are melted and the melt is formed into the bristle carrier with the outlet opening and riser pipe.

Diese bereits zuvor erwähnte Möglichkeit der Ausbildung des erfindungsgemäßen Verfahrens gestattet in einem einzi­gen Arbeitsgang das Herstellen des Borstenträgers und ersetzt somit das gesonderte Befestigen der Borsten und des Steigrohrs.This previously mentioned possibility of designing the method according to the invention allows the bristle carrier to be produced in a single operation and thus replaces the separate fastening of the bristles and the riser pipe.

Die vorgenannte Ausführung läßt sich in praktischer Hin­sicht dadurch verwirklichen, daß die befestigungsseitigen Enden der Borsten zunächst unter Verkürzung ihrer Länge zu einem scheiben- oder plattenförmigen Borstenträger auf­geschmolzen und gleichzeitig oder unmittelbar anschließend daran durch Aufschmelzen des Borstenträgers und gegebenen­falls der im Bündel innen liegenden Borsten die Austritts­öffnung und das Steigrohr in den Borstenträger eingeformt werden. Dabei ist es besonders vorteilhaft, wenn auch die innen liegenden Borsten mit aufgeschmolzen werden, so daß ein fester Verbund gegeben ist.The above-mentioned embodiment can be implemented in practical terms in that the attachment-side ends of the bristles are first melted to a disk-shaped or plate-shaped bristle carrier, shortening their length, and simultaneously or immediately thereafter by melting the bristle carrier and, if appropriate, the bristles lying inside the bundle, the outlet opening and the riser tube are molded into the bristle holder. It is particularly advantageous if the inner bristles are also melted, so that a firm bond is given.

Das erfindungsgemäße Verfahren gibt weiterhin die Möglich­keit, daß beim Umformen der Schmelze des Borstenträgers und gegebenenfalls der Borsten zu dem Steigrohr die Borsten unter Bildung des Kanals nach außen verdrängt werden.The method according to the invention also gives the possibility that when the melt of the bristle carrier and possibly the bristles are formed into the riser tube, the bristles are displaced outwards to form the channel.

Die Herstellung des medienführenden Kanals in dem Borsten­bündel ist prinzipiell auf zwei Arten möglich, indem ent­weder die Borsten unter entsprechend winkliger Anstellung im Bündel vorbereitet und anschließend an ihren befesti­gungsseitigen Enden aufgeschmolzen und umgeformt werden, doch gibt das erfindungsgemäße Verfahren auch die Möglich­keit, die Borsten im Bereich ihres nutzungsseitigen Endes eng zu fassen und das Steigrohr in das Bündel einzuformen, so daß sich bei diesem Formvorgang zugleich auch der Kanal innerhalb des Bündels ausbildet.The production of the media-carrying channel in the bristle bundle is possible in two ways, either by preparing the bristles in the bundle with appropriate angular positioning and then melting and reshaping them at their fastening-side ends, but the method according to the invention also gives the possibility of bristles in the area of their end on the use side and to form the riser pipe into the bundle, so that the channel also forms within the bundle during this molding process.

Eine weitere vorteilhafte Variante des Verfahrens zeichnet sich dadurch aus, daß die Borsten in eine Öffnung des das fluide Medium enthaltenden Behälters oder eines Verschlusses für diesen eingeführt und anschließend vom eingeführten Ende her aufgeschmolzen werden und daß dabei die Schmelze an die Wandung der Öffnung zur Verankerung des Borsten­trägers verdrängt wird.Another advantageous variant of the method is characterized in that the bristles are introduced into an opening of the container containing the fluid medium or a closure for the latter and then melted from the inserted end, and that the melt is attached to the wall of the opening for anchoring the Bristle carrier is displaced.

Diese Verfahrensvariante bringt den Vorteil mit sich, daß anläßlich der Ausbildung des Borstenträgers und des Steig­rohrs sogleich die Befestigung der aus Borsten, Borsten­träger und Steigrohr bestehenden Einheit an dem das fluide Medium enthaltenden Behälter oder an einem diesen Behälter abschließenden Verschluß erfolgt.This variant of the method has the advantage that, on the occasion of the formation of the bristle carrier and the riser tube, the unit consisting of bristles, bristle carrier and riser tube is immediately attached to the container containing the fluid medium or to a closure closing this container.

Zu diesem Zweck ist es vorteilhaft, wenn die Öffnung des Behälters bzw. des Verschlusses Vorsprünge oder Hinter­schneidungen aufweist, auf bzw. in die das geschmolzene Borstenmaterial geformt wird.For this purpose, it is advantageous if the opening of the container or of the closure has projections or undercuts on or into which the molten bristle material is formed.

Die Vorsprünge können beispielsweise in Form von Rippen, die Hinterschneidungen in Form von Nuten ausgebildet sein. Durch das Auf- bzw. Einformen des geschmolzenen Borsten­materials wird nicht nur der Borstenträger erhalten, sondern zugleich dessen formschlüssige Befestigung im Behälter bzw. in Verschluß.The projections can be designed, for example, in the form of ribs, and the undercuts in the form of grooves. By molding or molding the molten bristle material, not only is the bristle carrier obtained, but at the same time its form-fitting attachment in the container or in the closure.

Statt der vorgenannten Verfahrenstechnik kann entsprechend der eingangs genannten Alternative das Steigrohr auch nur aus dem vorgefertigten Borstenträger erzeugt werden. Dies geschieht mit Vorteil in der Weise, daß die befestigungs­seitigen Enden der Borsten am Borstenträger durch thermi­sches Schmelzen befestigt und anschließend der Borstenträger zumindest teilweise aufgeschmolzen und die Schmelze unter Bildung des Steigrohrs in das Bortstenbündel verdrängt wird.Instead of the aforementioned process technology, the riser pipe can also be produced only from the prefabricated bristle carrier in accordance with the alternative mentioned at the beginning. This is advantageously done in such a way that the attachment-side ends of the bristles are attached to the bristle carrier by thermal melting and then the bristle carrier is at least partially melted and the melt is displaced into the bristle bundle to form the riser tube.

Auch hierbei wird mit Vorteil so verfahren, daß anläßlich des Verdrängens der Schmelze des Borstenträgers zur Bildung des Steigrohrs die Borsten zur Bildung des Kanals nach außen verdrängt werden, so daß zugleich der Kanal innerhalb des Bündels erzeugt wird. Dies setzt jedoch voraus, daß die Borsten eines Bündels mit Abstand vom Borstenträger zumindest während des Aufschmelzens und Umformens eng gefaßt sind.Here too, the procedure is advantageously such that when the melt of the bristle carrier is displaced to form the riser tube, the bristles are displaced outwards to form the channel, so that the channel is simultaneously generated within the bundle. However, this presupposes that the bristles of a bundle are closely spaced from the bristle carrier, at least during melting and reshaping.

Schließlich gibt das erfindungsgemäße Verfahren auch die Möglichkeit, daß der Borstenträger in der Form eines Ver­schlusses für den das fluide Medium enthaltenden Behälter hergestellt wird.Finally, the method according to the invention also gives the possibility that the bristle carrier is produced in the form of a closure for the container containing the fluid medium.

Auf diese Weise ist es möglich, nicht nur die Erzeugung von Borstenträger und Steigrohr sowie die Befestigung der Borsten, sondern darüber hinaus auch noch die Ausbildung des Verschlusses für den das fluide Medium enthaltenden Behälter in einem einzigen Arbeitsgang zu erzeugen. Es braucht dann der Verschluß mit dem integrierten Borsten­träger und Steigrohr sowie den Borsten nur noch auf den Behälter aufgesetzt zu werden.In this way it is possible not only to produce the bristle carrier and riser pipe and the attachment of the bristles, but also to produce the closure for the container containing the fluid medium in a single operation. The closure with the integrated bristle holder and riser tube and the bristles then only need to be placed on the container.

Die wesentlichen Merkmale einer Vorrichtung zur Durch­führung des erfindungsgemäßen Verfahrens bestehen darin, daß ein erstes heizbares Formwerkzeug mit einer ersten Form­fläche zum Einformen einer Vertiefung in die Schmelze von Borsten und/oder Borstenträger und ein zweites heizbares Formwerkzeug mit einem in die Vertiefung eindringenden Dorn zur Ausbildung des Steigrohrs vorgesehen ist. Mit Vorteil ist dabei für die Borsten eine sie eng umfassende Führung mit Abstand von dem Borstenträger vorgesehen, so daß beim Einformen des Steigrohrs mittels des Dorns zu­gleich auch der Kanal innerhalb des Bündels gebildet wird.The essential features of an apparatus for performing the method according to the invention are that a first heatable molding tool with a first molding surface for forming a depression in the melt of bristles and / or bristle carriers and a second heatable molding tool with a mandrel penetrating into the depression to form the Riser pipe is provided. Advantageously, a narrow guide is provided for the bristles at a distance from the bristle carrier, so that when the riser tube is molded in, the mandrel also forms the channel within the bundle.

Nachstehend ist die Erfindung anhand von in der Zeichnung wiedergegebenen Ausführungsbeispielen beschrieben. In der Zeichnung zeigen:

  • Figur 2 einen der Figur 1 entsprechenden Schnitt einer zweiten Ausführungs­form;
  • Figur 3 - 5 verschiedene Stufen einer Ausfüh­rungsform des erfindungsgemäßen Verfahrens anhand einer schematisch gezeigten Vorrichtung und
  • Figur 6 - 9 verschiedene Stufen einer zweiten Ausführungsform des Verfahrens.
The invention is described below with reference to exemplary embodiments shown in the drawing. The drawing shows:
  • 1 shows a cross section of a first embodiment of a device produced according to the invention;
  • Figure 2 shows a section corresponding to Figure 1 of a second embodiment;
  • Figures 3 - 5 different stages of an embodiment of the method according to the invention using a schematically shown device and
  • Figures 6-9 different stages of a second embodiment of the method.

In Figur 1 und 2 ist jeweils ein Borstenbündel 1 erkennbar, dessen Borsten 2 winklig angestellt sind derart, daß das Bündel 1 sich zu seinem freien Ende 3 hin konisch verjüngt. Innerhalb des Borstenbündels 1 ist ein Kanal 4 vorhanden, der sich gleichfalls zum Bündelende 3 hin konisch verjüngt und frei von Borsten ist. Die einzelnen Borsten 2 sind dabei so angestellt, daß sie zum Bündelende 3 hin dicht aneinander anschließen und den Kanal 4 abschließen.1 and 2 each show a bristle bundle 1, the bristles 2 of which are set at an angle such that the bundle 1 tapers conically towards its free end 3. Inside the bristle bundle 1 there is a channel 4, which also tapers conically towards the bundle end 3 and is free of bristles. The individual bristles 2 are adjusted so that they close together towards the end of the bundle 3 and close the channel 4.

Der Kanal 4 setzt eine Öffnung 5 im Borstenträger 6 fort, wobei an die Öffnung 5 ein Steigrohr 7 anschließt, das bis in den Kanal 4 des Borstenbündels 1 hineinragt.The channel 4 continues an opening 5 in the bristle carrier 6, a riser pipe 7 adjoining the opening 5, which projects into the channel 4 of the bristle bundle 1.

Bei dem Ausführungsbeispiel gemäß Figur 1 ist das Steig­rohr 7 dadurch gebildet, daß die Borsten 2 an ihrem befe­ stigungsseitigen Ende aufgeschmolzen und zu dem Borsten­träger 6 mit dem Steigrohr 7 umgeformt werden. Der Borsten­träger 6 ist in einer Kappe oder einem Verschluß 8 eines das fluide Medium enthaltenden Behälters befestigt. Die Befestigung kann formschlüssig erfolgen, indem beispiels­weise der Verschluß an der Innenseite seiner Öffnung eine Rippe 9 aufweist, auf die der Borstenträger 6 mit einer entsprechend ausgebildeten Nut aufgeprellt wird. Es kann aber der Borstenträger 6 auch anläßlich seiner Herstellung innerhalb der Öffnung des Verschlusses 8 auf die Rippe 9 aufgeformt werden.In the embodiment of Figure 1, the riser pipe 7 is formed in that the bristles 2 on their BEFE Melting end melted and formed into the bristle carrier 6 with the riser 7. The bristle carrier 6 is fastened in a cap or a closure 8 of a container containing the fluid medium. The attachment can be positive, for example, by the closure on the inside of its opening having a rib 9 onto which the bristle carrier 6 is bounced with a correspondingly designed groove. However, the bristle carrier 6 can also be molded onto the rib 9 within the opening of the closure 8 on the occasion of its manufacture.

Bei dem Ausführungsbeispiel gemäß Figur 2 bildet der Bor­stenträger 10 unmittelbar den oberen Abschluß eines das Fluid enthaltenden Behälters. Bei diesem Ausführungsbei­spiel ist das Steigrohr 11 aus dem Material des Borsten­trägers 10 durch Aufschmelzen und Umformen hergestellt. Die Borsten 2 des Bündels 1 sind entweder auf die Stirn­seite des Borstenträgers 10 aufgeschweißt oder aber es wird durch Aufschmelzen des befestigungsseitigen Endes der Borsten eine Ringscheibe 12 gebildet, die in den Bor­stenträger 10 mechanisch eingesetzt ist.In the exemplary embodiment according to FIG. 2, the bristle carrier 10 directly forms the upper end of a container containing the fluid. In this embodiment, the riser tube 11 is made from the material of the bristle carrier 10 by melting and reshaping. The bristles 2 of the bundle 1 are either welded onto the end face of the bristle carrier 10 or else an annular disk 12 is formed by melting the attachment-side end of the bristles, which is mechanically inserted into the bristle carrier 10.

In den Figuren 3 bis 5 ist ein Ausführungsbeispiel zur Herstellung der Ausführungsform gemäß Figur 1 gezeigt. Bei dieser Verfahrensvariante werden auf Länge geschnittene und zu einem Bündel 1 zusammgefaßte Borsten 2 von oben her in eine Hülse 13 eingeführt, die beispielsweise den oberen Abschluß des das Fluid enthaltenden Behälters bildet. Gegebenenfalls können die Borsten 2 an ihrem einführungs­seitigen Ende durch Aufschmelzen und Bildung einer dünnen Platte 6 miteinander verbunden sein. Die Hülse 13 weist innenseitig eine Rippe 14 und in ihrem oberen Bereich nach innen geneigte Wandungen 15 auf.FIGS. 3 to 5 show an exemplary embodiment for producing the embodiment according to FIG. 1. In this variant of the method, bristles 2 cut to length and combined to form a bundle 1 are introduced from above into a sleeve 13 which, for example, forms the upper end of the container containing the fluid. If necessary, the bristles 2 can be connected to one another at their insertion end by melting and forming a thin plate 6. The sleeve 13 has a rib 14 on the inside and walls 15 inclined inward in its upper region.

In die Hülse 13 kann von unten her ein erstes heizbares Formwerkzeug 16 einfahren, das eine ebene Stirnfläche 17 und eine Formfläche in Gestalt einer Kegelspitze 18 aufweist. Mit dem heizbaren Formwerkzeug 16 werden die Borsten 2 an ihrem Ende aufgeschmolzen und die Schmelze nach oben ver­drängt, so daß sie den gesamten Querschnitt der Hülse 13 ausfüllt und gleichzeitig auf die Rippe 14 aufgeformt wird. Im Zentrum des solchermaßen aufgeschmolzenen und die Borsten 2 miteinander verbindenden Borstenträgers 6 entsteht durch die Kegelspitze 19 eine zentrale Einprägung 19. Dadurch wird die Schmelze im zentralen Bereich nach außen verdrängt, so daß auch die Borsten 2 an ihren Wurzeln nach außen wandern und sich dadurch auf ihrer gesamten Länge nach innen neigen, so daß sich im Zentrum der Kanal 4 ausbildet. Zugleich ver­kürzen sich die Borsten am Ende des Bündels 3 von innen nach außen.A first heatable molding tool 16 can be inserted into the sleeve 13 from below, which has a flat end face 17 and a shaping surface in the form of a cone tip 18. With the heatable molding tool 16, the bristles 2 are melted at their end and the melt is displaced upward, so that it fills the entire cross section of the sleeve 13 and is simultaneously molded onto the rib 14. In the center of the bristle carrier 6 melted in this way and connecting the bristles 2 to one another, a central indentation 19 is created by the cone tip 19. As a result, the melt in the central region is displaced outward, so that the bristles 2 also migrate outward at their roots and thereby open up their entire length incline so that the channel 4 is formed in the center. At the same time, the bristles at the end of the bundle 3 shorten from the inside out.

Nach Entfernen des Formwerkzeugs 16 wird in die Hülse 13 ein heizbares Formwerkzeug 20 mit einem zentralen Dorn 21 eingefahren, der gleichfalls erhitzt ist. Der Dorn 21 fährt in die Vertiefung 19 ein, schmilzt das Material des Bor­stenträgers, vor allem aber auch der innen liegenden Borsten auf und bildet aus der so entstehenden Schmelze das Steig­rohr 7 (Figur 5). Dabei wird der Kanal 4 noch stärker aus­geformt. Auf diese Weise werden der Borstenträger 6 und dessen Verbindung mit den Borsten 2 sowie das Steigrohr 7 und die Verbindung zwischen Borstenträger 6 und Hülse 13 in aufeinanderfolgenden Schmelz- und Umformvorgängen her­gestellt. Abschließend kann das Borstenbündel 1 an seinem Ende 3 noch zugespitzt werden, um einen feinen Auftrag des fluiden Mediums zu ermöglichen.After removal of the mold 16, a heatable mold 20 with a central mandrel 21 is inserted into the sleeve 13, which is also heated. The mandrel 21 moves into the recess 19, melts the material of the bristle carrier, but above all also the bristles lying on the inside, and forms the riser pipe 7 from the melt thus formed (FIG. 5). The channel 4 is shaped even more. In this way, the bristle carrier 6 and its connection to the bristles 2, as well as the riser pipe 7 and the connection between the bristle carrier 6 and the sleeve 13 are produced in successive melting and forming processes. Finally, the bristle bundle 1 can be tapered at its end 3 in order to enable a fine application of the fluid medium.

Bei dem Ausführungsbeispiel gemäß Figuren 6 bis 9 werden nicht einzelne Borstenbündel, sondern Endlosstränge ver­arbeitet, indem ein Endlosstrang mit einer der gewünschten Anzahl im Bündel entsprechenden Anzahl von Borsten 2 durch eine Führung 22, die die Borsten eng umfaßt, dem Abschluß 8 zugeführt wird. Der Abschluß 8 weist innenseitig an seiner Öffnung wiederum eine Rippe 14 auf. Der Endlosstrang 23 wird soweit in den Abschluß 8 zugeführt, daß sein vorlaufendes Ende 24 in Zuführrichtung jenseits der Rippe 14 liegt. Anschließend fährt wiederum von unten ein heizbares Form­werkzeug 16 entsprechend dem in Figur 4 gezeigten Werkzeug ein. Dabei wird der Borstenstrang 23 von seinem vorlaufenden Ende 24 her aufgeschmolzen, bis wiederum ein Borstenträger 6 ausgebildet ist, der auf die Rippe 14 des Abschlusses 8 aufgeformt ist. Dabei kann die Führung 22 abgesenkt werden, um mit ihrer vorderen Stirnseite den oberen Abschluß für das aufgeschmolzene und umgeformte Material zu bilden. Die Führung 22 taucht dabei in den Abschluß 8 ein, so daß dessen Kragen 26 das Borstenbündel 1 außenseitig umschließt.In the exemplary embodiment according to FIGS. 6 to 9, not individual bristle bundles but rather continuous strands are processed by an endless strand with a number of bristles 2 corresponding to the desired number in the bundle a guide 22, which closely surrounds the bristles, is fed to the closure 8. The end 8 in turn has a rib 14 on the inside of its opening. The endless strand 23 is fed into the closure 8 to such an extent that its leading end 24 lies beyond the rib 14 in the feed direction. A heatable molding tool 16 then moves in again from below in accordance with the tool shown in FIG. The bristle strand 23 is melted from its leading end 24 until a bristle carrier 6 is again formed, which is molded onto the rib 14 of the closure 8. The guide 22 can be lowered to form the upper end for the melted and formed material with its front face. The guide 22 dips into the closure 8 so that its collar 26 surrounds the bristle bundle 1 on the outside.

Mit den in den Figuren 3 bis 9 gezeigten Verfahrensschritten kann die Ausführungsform gemäß Figur 1 hergestellt werden. In ähnlicher Weise läßt sich die Ausführungsform gemäß Figur 2 erzeugen, indem die Borsten 2 auf der Scheibe 12 thermisch befestigt werden oder aber diese durch thermisches Schmelzen der Borsten erzeugt wird. Anschließend wird die Scheibe 12 in den Borstenträger 10 eingesetzt, wobei dieser zunächst eine ebene, geschlossene Stirnwand aufweist, auf der die Scheibe 12 aufliegt. Dann wird mit den zu Figuren 3 bis 9 beschriebenen heizbaren Formwerkzeugen 16, 20 die Öffnung 5 und das Steigrohr 11 durch Aufschmelzen und Um­formen erzeugt, wobei auch hier die Borsten unten nach außen verdrängt und oben gegeneinander geneigt werden.With the method steps shown in FIGS. 3 to 9, the embodiment according to FIG. 1 can be produced. The embodiment according to FIG. 2 can be produced in a similar manner by the bristles 2 being thermally fastened on the disk 12 or by the bristles being thermally melted. The disc 12 is then inserted into the bristle carrier 10, which initially has a flat, closed end wall on which the disc 12 rests. Then, with the heatable molding tools 16, 20 described for FIGS. 3 to 9, the opening 5 and the riser pipe 11 are produced by melting and reshaping, the bristles being displaced outwards at the bottom and inclined towards one another at the top.

Anschließend wird die Führung 22 hochgefahren und der Abschluß 8 gegebenenfalls abgesenkt. Daraufhin fährt das Formwerkzeug 20 mit dem Dorn 21, das dem in Figur 5 gezeig­ten entspricht, in den Abschluß 8 von unten ein und es wird das Steigrohr 7 mittels des Dorns 21 durch Aufschmelzen und Umformen des Borstenträgers 6 und/oder der im Zentrum liegenden Borsten 2 erzeugt. Dabei wird zugleich der Kanal 4 im Zentrum des Endlosstrangs 23 ausgebildet. Schließlich wird mittels eines querlaufenden Messers 25 ein Bündel vom Endlosstrang 23 abgelängt und dieses gegebenenfalls, wie in Figur 9 gezeigt, anschließend noch angespitzt.The guide 22 is then raised and the closure 8 is lowered, if necessary. Thereupon, the molding tool 20 with the mandrel 21, which corresponds to that shown in FIG. 5, moves into the closure 8 from below and the riser tube 7 becomes by means of the mandrel 21 by melting and reshaping the bristle carrier 6 and / or in the center lying bristles 2 generated. The channel 4 is simultaneously formed in the center of the endless strand 23. Finally, a bundle is cut to length from the endless strand 23 by means of a transverse knife 25 and, as shown in FIG. 9, this is then possibly sharpened.
