Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen von wenigstens einfach gewinkelten Profilen mit drehangetriebenen Bürstwalzen. Gegebenfalls ist diese Vorrichtung auch mit Einrichtungen zum Zuführen von Reinigungsflüssigkeit auf die Bürstwalzen und/oder das zu reinigende Profil, mit einer Spülvorrichtung und mit Düsen zum Trocknen der gereinigten Profile ausgerüstet.The invention relates to a device for cleaning at least single-angled profiles with rotating brush rollers. If appropriate, this device is also equipped with devices for supplying cleaning liquid to the brush rollers and / or the profile to be cleaned, with a rinsing device and with nozzles for drying the cleaned profiles.

Bisher ist es bekannt, zum Reinigen von Profilen, wie beispielsweise U-Profilen, L-Profilen od. dgl. Bürstwalzen zu verwenden, die senkrecht zur Drehachse ausgerichtete Borsten oder Borstenbüschel aufweisen. Bei diesen bekannten Vorrichtungen ist es notwendig Bürstwalzen vorzusehen, die oberhalb und unterhalb des zu reinigenden Profils angeordnet sind, sowie weitere Bürstwalzen vorzusehen, die um zu den vorgenannten Bürstwalzen senkrecht ausgerichtete Achsen drehbar sind, und die an den Schenkeln der U-Profile von innen und von außen her angreifen.So far, it has been known to use brush rollers for cleaning profiles, such as U-profiles, L-profiles or the like, which have bristles or tufts of bristles oriented perpendicular to the axis of rotation. In these known devices, it is necessary to provide brush rollers, which are arranged above and below the profile to be cleaned, and to provide further brush rollers, which are rotatable about axes oriented perpendicular to the aforementioned brush rollers, and which on the legs of the U-profiles from the inside and attack from the outside.

Wegen der Vielzahl von Bürstwalzen, die notwendig ist, damit die gesamte Oberfläche des zu reinigenden Profils bearbeitet (gereinigt) werden kann, sind die bekannten Vorrichtungen vergleichsweise aufwendig.Because of the large number of brush rollers that are necessary so that the entire surface of the profile to be cleaned can be processed (cleaned), the known devices are comparatively complex.

Die SU 1 248 763 zeigt und beschreibt eine Topfbürste, deren Borsten zu Einzelbüscheln zusammengefaßt sind, wobei zwischen den Borstenbüscheln Abstände vorliegen, die dazu bestimmt sind, in quer zur Längserstreckung eines Werkteiles verlaufende Ausnehmungen, z.B. zwischen Zähne desselben einzudringen und dort wirksam zu werden. Diese aus der SU 1 248 763 bekannte Bürste besitzt lediglich eine Bürstwalze, deren Borsten mit der Drehachse der Bürstwalze einen spitzen Winkel einschließen. Im übrigen ist die in der SU 1 248 763 beschriebene Topfbürste nicht zur Reinigung langgestreckter Profile geeignet.SU 1 248 763 shows and describes a pot brush, the bristles of which are combined into individual tufts, with distances between the tufts of bristles which are intended to penetrate into recesses running transversely to the longitudinal extension of a workpiece, for example between teeth thereof, and to take effect there. This brush known from SU 1 248 763 has only one brush roller, the bristles of which form an acute angle with the axis of rotation of the brush roller. Otherwise, the pot brush described in SU 1 248 763 is not suitable for cleaning elongated profiles.

Die GB-PS 2 194 135 beschreibt eine Bodenbürste mit einem plattenförmigen Bürstorgan, das im entlasteten Zustand eine leicht konische Form einnimmt. Die am Boden einwirkende Fläche des Bürstorganes besteht aus lose gesponnenen Polymerfasern, die mit einem Klettverschluß an einer Trägerplatte befestigt werden können.GB-PS 2 194 135 describes a floor brush with a plate-shaped brush member which assumes a slightly conical shape when unloaded. The surface of the brush element acting on the floor consists of loosely spun polymer fibers, which can be attached to a carrier plate with a Velcro fastener.

Die GB-PS 2 229 376 befaßt sich mit einer Vorrichtung, die zum Reinigen von Kanälen bei Abwasserkläranlagen bestimmt ist. Diese Reinigungsvorrichtung ist mit einer Bürste versehen, an der flexible Borsten vorgesehen sind, die bei Betrieb der Vorrichtung, die in Fig. 1 der GB-PS 2 229 376 gezeigte Lage einnehmen. Die GB-PS 2 229 376 zeigt eine Bürste mit von der Bürste radial abstehenden Borsten und mit von der an der Drehachse angeschlossenen Seite gegenüberliegenden Stirnfläche der Bürste teils axial, teils konisch abstehenden Borsten. Diese aus der GB-PS 2 229 376 bekannte Bürstenanordnung ist ausschließlich in der Lage, die Innenflächen von Kanälen od. dgl. zu reinigen, wobei der gesamte Bürstenkörper im Inneren des zu reinigenden Kanals aufgenommen sein muß.GB-PS 2 229 376 is concerned with a device which is intended for cleaning channels in sewage treatment plants. This cleaning device is provided with a brush on which flexible bristles are provided which, when the device is in operation, assume the position shown in FIG. 1 of GB-PS 2 229 376. GB-PS 2 229 376 shows a brush with bristles protruding radially from the brush and with an end face of the brush which is partly axially, partly conically protruding from the end face of the brush connected to the axis of rotation. This brush arrangement known from GB-PS 2 229 376 is only able to clean the inner surfaces of channels or the like, the entire brush body having to be accommodated inside the channel to be cleaned.

Die WO 86/07292 beschreibt eine Reinigungsvorrichtung, die mehrere an einem elastischen Träger befestigte gebogene Drahtstücke aufweist. Diese Reinigungsvorrichtung kann beispielsweise scheibenförmig ausgeführt sein und wird in das Spannfutter einer elektrischen Antriebsmaschine eingesetzt. Die gebogenen Drahtstücke sind in dem Träger aus elastischem Werkstoff verschwenkbar gelagert, so daß sie sich bei Betrieb der Vorrichtung aufstellen können.WO 86/07292 describes a cleaning device which has a plurality of bent wire pieces fastened to an elastic support. This cleaning device can, for example, be disc-shaped and is inserted into the chuck of an electric drive machine. The bent pieces of wire are pivotally mounted in the carrier made of elastic material, so that they can stand up when the device is in operation.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Gattung anzugeben, die einfacher aufgebaut ist und mit weniger Bürstwalzen das Auslangen findet und dennoch eine zuverlässige Reinigung aller Flächen des Profils gestattet.The invention is based on the object of specifying a device of the type mentioned at the outset, which is of simpler construction and has less brush rollers and is nevertheless capable of reliably cleaning all surfaces of the profile.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß wenigstens zwei der Bürstwalzen Borsten oder Borstenbüschel aufweisen, die mit der Drehachse der Bürstwalze einen spitzen Winkel einschließen, wobei die Borsten oder Borstenbüschel der beiden Bürstwalzen zueinander in entgegengesetzte Richtungen geneigt sind.According to the invention, this object is achieved in that at least two of the brush rollers have bristles or tufts of bristles which tip one with the axis of rotation of the brush roller Include angles, the bristles or tufts of bristles of the two brush rollers are inclined to each other in opposite directions.

Da bei der erfindungsgemäßen Vorrichtung Bürstwalzen mit in entgegengesetzte Richtungen geneigten Borsten oder Borstenbüscheln vorgesehen sind, werden von diesen auch die Bereiche der Profile zuverlässig gereinigt, welche zur Drehachse der Bürstwalzen senkrecht ausgerichtet sind. Dadurch, daß die Borsten oder Borstenbüschel der Bürstwalzen abwechselnd in entgegengesetzte Richtungen geneigt sind, werden sowohl die Innen- als auch die Außenseiten der senkrecht zur Drehachse ausgerichteten Bereiche der Profile zuverlässig gereinigt.Since brush rollers with bristles or tufts of bristles inclined in opposite directions are provided in the device according to the invention, they also reliably clean the areas of the profiles which are oriented perpendicular to the axis of rotation of the brush rollers. Characterized in that the bristles or tufts of bristles of the brush rollers are alternately inclined in opposite directions, both the inside and the outside of the areas of the profiles aligned perpendicular to the axis of rotation are reliably cleaned.

Aber nicht nur die senkrecht zur Drehachse der Bürstwalzen ausgerichteten Bereiche der Profile können mit der erfindungsgemäßen Vorrichtung zuverlässig gereinigt werden, sondern auch die den Bürstwalzen zugekehrten, zu deren Drehachsen parallel ausgerichteten Bereiche der Profile, so daß alle den Bürstwalzen zugekehrten Flächen des Profils, ganz gleich, ob diese senkrecht oder parallel zur Drehachse der Bürstwalzen ausgerichtet sind, gereinigt werden können.But not only the areas of the profiles aligned perpendicular to the axis of rotation of the brushing rollers can be reliably cleaned with the device according to the invention, but also the areas of the profiles oriented parallel to the axis of rotation of the brushing rollers, so that all surfaces of the profile facing the brushing rollers are identical whether they are aligned perpendicular or parallel to the axis of rotation of the brush rollers can be cleaned.

Falls gewünscht wird, auch die von den Bürstwalzen abgewendeten Bereiche der Profile zu reinigen, kann zusätzlich eine mit senkrecht zur Drehachse der Bürstwalze ausgerichteten Borsten oder Borstenbüscheln bestückte Bürstwalze vorgesehen sein.If it is desired to also clean the areas of the profiles facing away from the brush rollers, a brush roller equipped with bristles or tufts of bristles oriented perpendicular to the axis of rotation of the brush roller can additionally be provided.

In einer Ausführungsform der Erfindung kann vorgesehen sein, daß die mit schräg gestellten Borsten oder Borstenbüscheln bestückten Bereiche der Bürstwalzen zueinander versetzt angeordnet sind. Diese Ausführungsform hat beispielsweise beim Reinigen von U-Profilen den Vorteil, daß die Borstenbüschel bzw. Borsten weniger stark abgenützt werden, da im Bereich des Schenkels des Profils, der gerade nicht gereinigt wird, keine Borsten vorgesehen sind. Um dennoch eine zuverlässige Reinigung auch des zwischen den Stegen liegenden Bereiches des Schenkels des U-Profils zu gewährleisten, kann vorgesehen sein, daß sich die mit schräg gestellten Borsten bestückten Bereiche überlappen.In one embodiment of the invention it can be provided that the areas of the brushing rollers equipped with inclined bristles or tufts of bristles are arranged offset to one another. This embodiment has the advantage, for example, when cleaning U-profiles that the bristle tufts or bristles are less worn, since no bristles are provided in the region of the leg of the profile that is not being cleaned. In order to ensure reliable cleaning of the area of the leg of the U-profile lying between the webs, it can be provided that the bristles are placed at an angle Areas overlap.

Eine in Fig. 1 gezeigte Vorrichtung zum Reinigen von wenigstens einfach gewinkelten Profilen 2 - im gezeigten Ausführungsbeispiel wird ein U-Profil gereinigt - besitzt einen Horizontalförderer, bestehend aus Förderrollen 1 oder ähnlichen Fördermitteln, welche das zu reinigende Profil 2 in Richtung des Pfeiles 3 durch die Vorrichtung bewegen. Oberhalb der Förderrollen 1 sind zwei Bürstwalzen 4 und 5 vorgesehen, die in einem nicht gezeigten Maschinengestell drehbar gelagert und mit einem Antrieb gekuppelt sind. Jeder der beiden Bürstwalzen 4 und 5 sind Sprühvorrichtungen 6 bzw. 7 für Reinigungsmittel zugeordnet. Diese Sprüheinrichtungen 6 und 7 spritzen Reinigungsmittel auf die Bürstwalzen 4 und 5 und/oder das Profil 2.A device shown in Fig. 1 for cleaning at least simply angled profiles 2 - in the embodiment shown, a U-profile is cleaned - has a horizontal conveyor, consisting of conveyor rollers 1 or similar conveying means, which through the profile 2 to be cleaned in the direction of arrow 3 move the device. Above the conveyor rollers 1, two brush rollers 4 and 5 are provided, which are rotatably mounted in a machine frame (not shown) and are coupled to a drive. Each of the two brush rollers 4 and 5 are assigned spray devices 6 and 7 for cleaning agents. These spray devices 6 and 7 spray cleaning agents onto the brush rollers 4 and 5 and / or the profile 2.

Im Anschluß an die Bürstwalzen 4 und 5 ist eine weitere, um eine zur Förderrichtung 3 senkrechte Achse 13, drehangetriebene Bürstwalze 8 vorgesehen, die auf der den Bürstenwalzen 4 und 5 gegenüberliegenden Seite des Profils 2 angreift. Auch der Bürstwalze 8 ist eine Sprüheinrichtung 9 für Reinigungsmittel zugeordnet.Following the brush rollers 4 and 5 there is a further brush roller 8, which is rotatably driven about an axis 13 perpendicular to the conveying direction 3 and which engages on the side of the profile 2 opposite the brush rollers 4 and 5. A spray device 9 for cleaning agents is also assigned to the brush roller 8.

Im Anschluß an die Bürstwalzen 4, 5 und 8 ist im gezeigten Ausführungsbeispiel noch eine Spüleinrichtung 10, 11, z.B. Düsen, aus denen eine Spülflüssigkeit auf das Profil 2 aufgebracht wird, um dieses zu spülen, und im Anschluß an diese eine Vorrichtung 12 zum Trocknen vorgesehen. Die Vorrichtung 12 zum Trocknen kann beispielsweise eine mit Druckluft beaufschlagte Düsenanordnung sein.Following the brush rollers 4, 5 and 8 is shown in Embodiment another rinsing device 10, 11, for example nozzles, from which a rinsing liquid is applied to the profile 2 in order to rinse it, and a device 12 for drying is provided after this. The device 12 for drying can be, for example, a nozzle arrangement to which compressed air is applied.

Aus der Schnittdarstellung von Fig. 2 ist ersichtlich, daß die Borsten oder Borstenbüschel 20 der Bürstwalze 4 in den Kern 21 der Bürstwalze 4 zur Drehachse 24 der Bürstwalze 4 unter einem spitzen Winkel α geneigt eingesetzt sind. Dadurch werden von der Bürstwalze 4 die in Fig. 2 mit 30 bzw. 31 bezeichneten Flächen der beiden Schenkel des U-Profils 2 und ein Teil der Innenfläche 33 des Steges des U-Profils 2 gereinigt.From the sectional view of Fig. 2 it can be seen that the bristles or tufts of bristles 20 of the brush roller 4 are inserted into the core 21 of the brush roller 4 to the axis of rotation 24 of the brush roller 4 inclined at an acute angle α. As a result, the surfaces of the two legs of the U-profile 2, designated 30 and 31 in FIG. 2, and part of the inner surface 33 of the web of the U-profile 2 are cleaned by the brush roller 4.

Die Bürstwalze 5 besitzt ebenfalls zu ihrem Kern 25 bzw. ihrer Drehachse 26 unter einem spitzen Winkel α geneigte Borsten bzw. Borstenbüschel 27, wobei jedoch die Borstenbüschel 27 in die andere Richtung geneigt sind als die Borstenbüschel bzw. Borsten 20 der Bürstwalze 4. Dadurch werden von den Borsten bzw. Borstenbüschel 27 der Bürstwalze 5 die in Fig. 3 mit 34 und 35 bezeichneten Flächen der Schenkel des U-Profiles 2 und der andere Bereich der Innenfläche 33 des Steges des U-Profiles 2 gereinigt.The brush roller 5 likewise has bristles or bristle tufts 27 inclined at an acute angle α to its core 25 or its axis of rotation 26, but the bristle tufts 27 are inclined in the other direction than the bristle tufts or bristles 20 of the brush roller 4. As a result from the bristles or tufts of bristles 27 of the brushing roller 5, the surfaces of the legs of the U-profile 2, designated 34 and 35 in FIG. 3, and the other area of the inner surface 33 of the web of the U-profile 2 are cleaned.

Die an der Unterseite des U-Profils, d.h. an der Außenfläche, die den Transportrollen 1 zugekehrt ist, angreifende Bürstwalze 8 kann, wie an sich bekannt, zu ihrer Achse 13 senkrecht ausgerichtete Borsten bzw. Borstenbüschel 14 besitzen.The at the bottom of the U-profile, i.e. on the outer surface facing the transport rollers 1, the brush roller 8, as is known per se, can have bristles or tufts 14 oriented perpendicular to its axis 13.

Es ist erkennbar, daß durch die besondere Ausbildung der Bürstwalzen 4 und 5 mit nur zwei Bürstwalzen alle ihnen zugekehrten Flächen des U-Profils 2, ganz gleich, ob diese parallel oder senkrecht zur Drehachse 24 bzw. 26 der Bürstwalzen 4 und 5 ausgerichtet sind, gereinigt werden.It can be seen that due to the special design of the brush rollers 4 and 5 with only two brush rollers, all surfaces of the U-profile 2 facing them, regardless of whether they are aligned parallel or perpendicular to the axis of rotation 24 or 26 of the brush rollers 4 and 5, getting cleaned.

Um zu vermeiden, daß die Borsten bzw. Borstenbüschel 20 bzw. 27 der Bürstwalzen 4 und 5, den freien Rand 38 bzw. 39 des Schenkels des U-Profils 2, der gerade nicht gereinigt wird, entlangreiben und somit einem erhöhten Verschleiß ausgesetzt sind, können die mit Borsten oder Borstenbüscheln 20 bzw. 27 bestückten Bereiche 44, 45 der Bürstwalzen 4 bzw. 5, so wie in den Fig. 4 und 5 gezeigt, angeordnet sein. Es ist ersichtlich, daß die Bestückungen der Bürstwalzen 4 und 5, bezogen auf die Förderrichtung, zueinander versetzt angeordnet sind und die Unterbrechung 43 in der Bestückung beispielsweise einmal auf der einen und dann auf der anderen Seite der Längsmittelebene 42 der Vorrichtung angeordnet ist. Zweckmäßigerweise überlappen die Bereiche 44, in welchen die Bürstwalzen 4 und 5 mit Borsten oder Borstenbüscheln 20 bzw. 27 bestückt sind, einander ein wenig, damit die Fläche 33 des Profils 2 zuverlässig gereinigt wird. Es ist erkennbar, daß bei dieser Ausführungsform die Außenseiten der Schenkel des U-Profils 2 von den im Bereich 45 angeordneten Borsten bzw. Borstenbüscheln 20 bzw. 27 bearbeitet werden, so daß auch bei dieser Ausführungsform alle Außenflächen des Profils 2 gereinigt werden.In order to avoid that the bristles or tufts of bristles 20 and 27 of the brush rollers 4 and 5, the free edge 38 and 39 of the leg of the U-profile 2, which is not being cleaned, rub along and are thus exposed to increased wear, the areas 44, 45 of the brush rollers 4 and 5, respectively, which are equipped with bristles or tufts of bristles 20 and 27, as shown in FIGS. 4 and 5, can be arranged. It can be seen that the assemblies of the brushing rollers 4 and 5 are arranged offset from one another with respect to the conveying direction and the interruption 43 in the assembly is arranged, for example, once on one side and then on the other side of the longitudinal center plane 42 of the device. The regions 44, in which the brush rollers 4 and 5 are equipped with bristles or tufts of bristles 20 and 27, expediently overlap one another a little so that the surface 33 of the profile 2 is reliably cleaned. It can be seen that in this embodiment, the outer sides of the legs of the U-profile 2 are processed by the bristles or tufts of bristles 20 and 27 arranged in the area 45, so that all the outer surfaces of the profile 2 are also cleaned in this embodiment.

Wenn keine Bestückung im Bereich 45 der Bürstwalzen 4 und 5 vorgesehen ist, können senkrecht zur Drehachse 24 bzw. 26, rotierende Bürstwalzen mit senkrecht zu ihren Drehachsen abstehenden Borsten oder Borstenbüscheln vorgesehen sein.If no equipment is provided in the area 45 of the brush rollers 4 and 5, rotating brush rollers with bristles or tufts of bristles protruding perpendicular to their axes of rotation can be provided perpendicular to the axis of rotation 24 or 26.

Um die Lage des mit Borsten oder Borstenbüscheln 20 bzw. 27 nicht bestückten Bereiches 43 der Breite des zu reinigenden Profils 2 anzupassen (damit der eine Schenkel mit seinem Rand 38 oder 39 in diesem Bereich 43 liegt), kann die Bürstwalze oder einer oder beide der bestückten Bereiche 44, 45 in Richtung der Drehachse der Bürstwalzen 4 und 5 verstellbar sein.In order to adjust the position of the area 43 not equipped with bristles or tufts of bristles to the width of the profile 2 to be cleaned (so that one leg with its edge 38 or 39 lies in this area 43), the brush roller or one or both of the equipped areas 44, 45 to be adjustable in the direction of the axis of rotation of the brush rollers 4 and 5.

Die Bürstwalzen 4, 5 können an verschiedene Profile oder Profilgrößen auch dadurch angepaßt werden, daß auf den Wellen 21, 25 der Bürstwalzen 4, 5 die Borsten bzw. Borstenbüschel 20, 27 tragende Hülsen 40 aufgeschoben werden. Die Hülsen 40 sind beispielsweise durch Nut-Feder-Kupplungen mit den Wellen 21, 25 drehfest verbunden und können durch Endscheiben oder Endkappen (nicht gezeigt) auf den Wellen 21, 25 in axialer Richtung festgelegt sein. Sollen nicht mit Borsten bzw. Borstenbüscheln 20, 27 bestückte Bereiche 43 der Bürstwalzen 4, 5 vorliegen, können auf die Wellen 21, 25, dort wo keine Borsten bzw. Borstenbüschel 20, 27 vorgesehen sein sollen, nackte Hülsen 41 aufgeschoben werden.The brushing rollers 4, 5 can also be adapted to different profiles or profile sizes in that sleeves 40 carrying the bristles or tufts of bristles 20, 27 are pushed onto the shafts 21, 25 of the brushing rollers 4, 5. The sleeves 40 are, for example, connected to the shafts 21, 25 in a rotationally fixed manner by means of tongue and groove couplings and can be fixed on the shafts 21, 25 in the axial direction by end disks or end caps (not shown). If areas 43 of the brush rollers 4, 5 are not to be provided with bristles or tufts of bristles 20, 27, can be pushed onto the shafts 21, 25 where no bristles or tufts of bristles 20, 27 are to be provided, bare sleeves 41.

Die in Fig. 6 in Draufsicht gezeigte Ausführungsform entspricht im wesentlichen der Ausführungsform von Fig. 1 bis 3, wobei aber die Achsen 24, 26 der Bürstwalzen 4 und 5 zur Förderrichtung (Pfeil 3) bzw. zur Längserstreckung des Profils 2 schräggestellt sind. Dabei entspricht die Schrägstellung (Winkel β) der Achsen 24 und 26 - diese sind entgegengesetzt schräggestellt - etwa dem Winkel α, mit dem die Borsten oder Borstenbüschel 20 bzw. 27 zu den Drehachsen 24 bzw. 26 schräggestellt sind. Für die in Fig. 6 gezeigte Ausführungsform können auch einzelne oder alle Bürstwalzen mit der in den Fig. 4 und 5 gezeigten Ausführungsform verwendet werden.The embodiment shown in plan view in FIG. 6 corresponds essentially to the embodiment of FIGS. 1 to 3, but with the axes 24, 26 of the brush rollers 4 and 5 being inclined to the conveying direction (arrow 3) or to the longitudinal extension of the profile 2. The inclination (angle β) of the axes 24 and 26 - these are oppositely inclined - approximately corresponds to the angle α with which the bristles or tufts 20 and 27 are inclined to the axes of rotation 24 and 26. Individual or all brushing rollers with the embodiment shown in FIGS. 4 and 5 can also be used for the embodiment shown in FIG. 6.

Die erfindungsgemäße Vorrichtung ist für die verschiedensten Formen von Profilleisten verwendbar, die wenigstens einmal gewinkelt ausgeführt sind. Auch können mit der erfindungsgemäßen Vorrichtung Profilleisten aus beliebigen Werkstoffen, z.B. auch solche aus Glas oder Metall (Stahl) gereinigt werden.The device according to the invention can be used for a wide variety of shapes of profile strips which are angled at least once. Profile strips made of any materials, e.g. also those made of glass or metal (steel) can be cleaned.

Um ein ungleichmäßiges Abnützen der Borsten oder Borstenbüschel 20 bzw. 27 an den Schenkeln des zu reinigenden U-Profiles, insbesondere an den freien Rändern 38 bzw. 39 der Schenkel zu vermeiden, können die Bürsten 4 und/oder 5 in Richtung ihrer Achsen 24, 26 langsam hin- und herbewegt werden (quer zur Vorschubrichtung (Pfeil 3) des zu reinigenden Profils 2). So gelangen Borsten oder Borstenbüschel über einen breiten Bereich der Bürsten 4 und/oder 5 in den Bereich der Schenkel des Profiles 2 und die Abnützung der Borsten oder Borstenbüschel 20 wird gleichmäßiger. Um die Bürsten 4 und/oder 5 in Richtung ihrer Achsen 24 bzw. 26 zu bewegen, können an ihren Wellen 21 bzw. 25 angreifende Linearmotore (Druckmittelmotore od. dgl.) vorgesehen sein, die doppelt wirken oder die, wenn sie nur einfach wirken, gegen Federn, welche die Wellen 21 bzw. 25 der Bürsten 4 und/oder 5 in einer Richtung belasten, arbeiten.In order to avoid uneven wear of the bristles or tufts of bristles 20 and 27 on the legs of the U-profile to be cleaned, in particular on the free edges 38 and 39 of the legs, the brushes 4 and / or 5 can be moved in the direction of their axes 24, 26 are slowly moved back and forth (transversely to the feed direction (arrow 3) of the profile 2 to be cleaned). Thus, bristles or tufts of bristles reach the area of the legs of the profile 2 over a wide area of the brushes 4 and / or 5 and the wear of the bristles or tufts of bristles 20 becomes more uniform. In order to move the brushes 4 and / or 5 in the direction of their axes 24 or 26, linear motors (pressure medium motors or the like) which act on their shafts 21 or 25 can be provided, which act twice or if they act only once , against springs, which load the shafts 21 and 25 of the brushes 4 and / or 5 in one direction.
