Description

Die Erfindung betrifft eine Dosiereinrichtung mit einem Behälter mit einem auf der Unterseite angeordneten Sieb zum Durchlaß von in Form von stäbchenförmigem Schüttgut anfallendem Flock und einer innerhalb des Behälters über dessen ganze Breite angeordneten Bürstenwalze im wesentlichen bestehend aus einer drehantreibbar im Behälter über an den beiden Enden über je in einer Behälterwand angeordneten Lageraugen gelagerten Welle und mehreren in Umfangsrichtung gleichmäßig verteilt angeordneten und im wesentlichen radial gerichtete Borsten tragenden Bürstenleisten, welche von mehreren in für eine Abstützung der Bürstenleisten auf der Welle geeigneter Verteilung drehfest angeordneten Bürstenleistenträgern gehalten werden.The invention relates to a metering device with a container with a sieve arranged on the underside for the passage of flock in the form of rod-shaped bulk material and a brush roller arranged within the container over its entire width, consisting essentially of a rotatably drivable in the container via at both ends each in a container wall arranged bearing eyes mounted shaft and a plurality of evenly distributed in the circumferential direction and substantially radially directed bristle-bearing brush strips, which are held by several in a rotatably arranged for supporting the brush strips on the shaft distribution brush holder.

Eine Dosiereinrichtung der oben beschriebenen Art gehört zum Stand der Technik. Solche Dosiereinrichtungen werden verwendet in Maschinen zur Beschichtung von Oberflächen mit sogenannten Flock. Der Flock fällt hierbei als stäbchenförmiges Schüttgut an, und wird von der in dem Behälter drehantreibbar angeordneten Bürstenwalze durch ein an der Unterseite des Behälters angeordnetes Sieb gestrichen. Nachdem der Flock das Sieb passiert hat, wird er in einem elektrostatischen Feld ausgerichtet und fällt dann auf eine entsprechend vorbereitete, zu beschichtende Unterlagen, wie z. B. einer Grundunterlage für einen Teppich.A metering device of the type described above belongs to the prior art. Such metering devices are used in machines for coating surfaces with so-called flock. The flock is obtained as rod-shaped bulk material and is brushed by the brush roller arranged in a rotatably drivable manner through a sieve arranged on the underside of the container. After the flock has passed the sieve, it is aligned in an electrostatic field and then falls on a correspondingly prepared underlay to be coated, such as B. a base for a carpet.

Zur Erzielung einer guten Beschichtungsqualität ist es erforderlich, daß der ausgerichtete Flock in möglichst gleichmässiger Menge pro Fläche aufgebracht wird, damit eine gleichmässige Beschichtungsdichte entsteht.To achieve a good coating quality, it is necessary that the aligned flock is applied in as uniform a quantity as possible per area, so that a uniform coating density is produced.

Die bekannten Einrichtungen erlauben nicht, die Beschichtungsdichte zu variieren, und erreichen darüber hinaus über die Länge der Bür-' stenwalze keine gleichmässige Beschichtungsdichte. Unterschiedliche Durchbiegungen der Welle der Bürstenwalze, unterschiedliche Durchbiegung der Borsten der Bürstenleiste, Verformungen des Durchstreichsiebes und viele andere Einflüsse verhindern eine befriedigend gleichmässige Beschichtungsdichte.The known devices do not allow to vary the coating density, and reach beyond the length of the citizens' stenwalze no uniform coating density. Different deflections of the shaft of the brush roller, different deflections of the bristles of the brush strip, deformations of the brush screen and many other influences prevent a satisfactorily uniform coating density.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Dosiereinrichtung vorzuschlagen, mit welcher eine sehr gleichmässige Beschichtungsdichte einer zu beschichtenden Unterlage bzw. eine Verteilungsdichte von gewünschtem Profil erreicht wird.The invention is therefore based on the object of proposing a metering device with which a very uniform coating density of a substrate to be coated or a distribution density of the desired profile is achieved.

Erfindungsgemäß wird diese Aufgabe bei einer Dosiereinrichtung der eingangs beschriebenen Art dadurch gelöst, daß mindestens ein Teil der vorhandenen Bürstenleistenträger Einrichtungen zum konkaven und/oder konvexen Durchbiegen der Bürstenleistenträger in radialer Richtung und zu deren Klemmung in eingerichteter Lage aufweisen.According to the invention, this object is achieved in a metering device of the type described at the outset in that at least some of the existing brush strip carriers have devices for concave and / or convex bending of the brush strip carriers in the radial direction and for clamping them in the set up position.

Mit Hilfe einer geeigneten Durchbiegung der Bürstenleistenträger ist es möglich, die Auswirkungen einer Siebverformung oder der Wellendurchbiegung der Antriebwelle der Bürstenwalze und weitere Auswirkungen von Unregelmässigkeiten zu kompensieren. Darüber hinaus wird es möglich, bewußt eine bestimmte Verteilung der Beschichtungsdichte zu erzeugen.With the help of a suitable deflection of the brush holder, it is possible to compensate for the effects of a screen deformation or the shaft deflection of the drive shaft of the brush roller and other effects of irregularities. In addition, it becomes possible to consciously generate a certain distribution of the coating density.

Es sind zwei Vorrichtungen gemäß FR-A-2118 144 und GB-A-1 142039 bekannt, bei denen eine gleichmäßige Beschichtungsdichte angestrebt wird. Eine Durchbiegung der Bürstenträger ist jedoch nicht vorgesehen. Auch ist eine beliebige Verteilungsdichte von gewünschtem Profil nicht möglich.Two devices according to FR-A-2118 144 and GB-A-1 142039 are known, in which a uniform coating density is sought. Bending of the brush holder is not provided. Any distribution density of the desired profile is also not possible.

Nach einer Ausgestaltung der Erfindung wird vorgeschlagen, daß die Bürstenleistenträger scheibenförmige Aufnahmeelemente mit gleichmässig über den Umfang verteilt angeordneten und radial nach außen offenen Aufnahmeschlitzen aufweisen, in deren radial einwärts liegendem Grund mindestens in radialer Richtung lageveränderliche Abdrückelemente sowie in mindestens einem Schenkel mindestens mit einer tangentialen Komponente lageveränderliche Klemmelemente zur Durchbiegung und Klemmung der Bürstenleisten vorgesehen sind. Dies ist ein besonders einfacher Aufbau der Bürstenwalze, der ein einfaches Ausrichten der Bürstenleisten mit einfachen Mitteln erlaubt und der zudem einen leichten Austausch der Bürstenleisten gewährleistet.According to one embodiment of the invention, it is proposed that the brush strip carriers have disk-shaped receiving elements with receiving slots arranged uniformly distributed over the circumference and open radially outwards, in whose radially inward-lying bottom positionally variable push-off elements and at least one leg with at least one tangential component variable-position clamping elements for bending and clamping the brush strips are provided. This is a particularly simple construction of the brush roller, which allows simple alignment of the brush strips with simple means and which also ensures easy replacement of the brush strips.

Nach einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, daß als Abdrückelemente und Klemmelemente Schrauben vorgesehen sind, welche in entsprechend angeordnete Gewindebohrungen der Aufnahmeschlitze der scheibenförmigen Aufnahmeelemente angeordnet sind. Dies ist die denkbar einfachste Möglichkeit, eine geeignete Durchbiegung der Bürstenleisten zu erreichen. Gleichzeitig ist diese Möglichkeit außerordentlich kostengünstig, denn Schrauben sind Normelemente und das Einbringen von Gewindebohrungen ist fertigungstechnisch problemlos.According to a further embodiment of the invention, it is proposed that screws are provided as push-off elements and clamping elements, which are arranged in correspondingly arranged threaded bores in the receiving slots of the disk-shaped receiving elements. This is the simplest possible way to achieve a suitable deflection of the brush strips. At the same time, this option is extremely inexpensive, because screws are standard elements and the production of threaded holes is problem-free in terms of production technology.

Wiederum nach einer Ausgestaltung der Erfindung wird vorgeschlagen, daß mindestens eine Lagerstelle der in Lageraugen gelagerten Welle mindestens in zum Sieb senkrechter Richtung bewegbar und feststellbar ist. Auf diese Art und Weise ist eine zusätzliche leichte Anpassung an die Länge der Borsten der Bürstenleisten möglich und es kann beispielsweise ein einseitiger Borstenverschleiß ausgeglichen oder in gewünschter Weise die Durchbiegung der Bürstenleisten durch eine zusätzliche Verstellung überlagert werden.Again according to an embodiment of the invention it is proposed that at least one bearing point of the shaft mounted in bearing eyes can be moved and locked at least in the direction perpendicular to the screen. In this way, an additional slight adjustment to the length of the bristles of the brush strips is possible and, for example, one-sided bristle wear can be compensated for or the deflection of the brush strips can be overlaid in the desired manner by an additional adjustment.

In einer ergänzenden Ausgestaltung der Erfindung ist vorgesehen, daß mindestens ein Lagerauge in einer relativ zur Behälterwand fixierten oder fixierbaren Bohrung drehbar und feststellbar gelagert ist, wobei die Lagerfläche für die Lagerung der Welle und die Lagerfläche, mit der das Lagerauge in der Bohrung gelagert ist, exzentrisch zueinander angeordnet sind. Hierdurch kann in der Größenordnung der vorgegebenen Exzentrizität die Antriebswelle der Bürstenwalze und damit die gesamte Bürstenwalze eine beliebige räumliche Lage einnehmen, wodurch ein weiterer Einfluß auf die Dichte des aus der Dosiereinrichtung abrieselnden Flocks erreicht werden kann.In a supplementary embodiment of the invention it is provided that at least one bearing eye is rotatably and fixably mounted in a bore which is fixed or fixable relative to the container wall, the bearing surface for the bearing of the shaft and the bearing surface with which the bearing eye is supported in the bore, are arranged eccentrically to each other. As a result, the drive shaft of the brush roller and thus the entire brush roller can assume any desired spatial position in the order of magnitude of the predetermined eccentricity, as a result of which a further influence on the density of the flock trickling out of the metering device can be achieved.

Eine weitere Ausgestaltung dieser Verstellmöglichkeit der Lage der Welle sieht vor, daß das Lagerauge an einer äußeren Umfangsfläche einen zu der Bohrung konzentrischen Zahnkranz aufweist, der mit einem in einem das Lagerauge übergreifenden Flansch angeordneten drehbaren Ritzel kämmt, wobei der Flansch weiter eine radial auf das Lagerauge wirkende Klemmschraube aufweist und an der Behälterwand befestigt ist. Auf diese Art und Weise kann mit einfachsten Mitteln von außen sehr rasch eine Veränderung der Lage der Welle herbeigeführt und die herbeigeführte Veränderung fixiert werden.Another embodiment of this adjustment of the position of the shaft provides that the bearing eye has on an outer circumferential surface a ring gear concentric with the bore, which meshes with a rotatable pinion arranged in a flange overlapping the bearing eye, the flange further extending radially onto the bearing eye has acting clamping screw and is attached to the container wall. In this way, a change in the position of the shaft can be brought about very quickly from the outside with the simplest means and the change brought about can be fixed.

Eine andere Ausgestaltung der Erfindung wiederum sieht vor, daß die Aufnahmeschlitze entgegen der Drehrichtung in Umfangsrichtung leicht geneigt angeordnet sind. Hierdurch werden die Borsten der Bürstenleisten direkt in die richtige Streichlage vorgeneigt und es wird ein Verhaken und Zerstoßen der Borsten am Sieb verhindert.Another embodiment of the invention in turn provides that the receiving slots are arranged slightly inclined in the circumferential direction against the direction of rotation. As a result, the bristles of the brush strips are tilted directly into the correct brushing position and the bristles are not caught and crushed on the sieve.

Schließlich ist nach einer Ausgestaltung der Erfindung noch vorgesehen, daß in jedem Aufnahmeschlitz außer der Bürstenleiste zusätzlich und unabhängig von dieser eine sich über die ganze Länge der Bürstenleiste erstreckende Borstenstützfeder in Drehrichtung hinter den Borsten der Bürstenleiste zu Abstützung der Borsten angeordnet ist.Finally, according to one embodiment of the invention it is also provided that in addition to the brush strip in each receiving slot, a bristle support spring extending over the entire length of the brush strip is arranged in the direction of rotation behind the bristles of the brush strip to support the bristles.

Die Erfindung soll nun anhand der beigefügten Zeichnungen näher erläutert werden.The invention will now be explained in more detail with reference to the accompanying drawings.

Eine Dosiereinrichtung 1 für die Dosierung von Flock weist im wesentlichen einen Behälter 2 auf (Figur 1), an dessen Unterseite 4 ein Sieb 3 angeordnet ist. Im Inneren des Behälters 2 befindet sich eine Bürstenwalze 5. Diese Bürstenwalze 5 besteht im wesentlichen aus einer drehantreibbaren Welle 8, deren beide Enden in der Lagerstelle 12 gelagert sind. Die Lagerstellen 12 sind hierbei in der Behälterwand 6 angeordnet.A metering device 1 for metering flock essentially has a container 2 (FIG. 1), on the underside 4 of which a sieve 3 is arranged. A brush roller 5 is located in the interior of the container 2. This brush roller 5 essentially consists of a shaft 8 which can be driven in rotation, the two ends of which are supported in the bearing point 12. The bearing points 12 are arranged in the container wall 6.

Auf der Welle 8 befinden sich in geeigneter Verteilung Bürstenleistenträger '11, die mit der Welle 8 drehfest verbunden sind und scheibenförmige Aufnahmeelemente 16 aufweisen. Die scheibenförmigen Aufnahmeelemente 16 weisen in Umfangsrichtung in gleichmässiger Verteilung Aufnahmeschlitze 17 auf, die radial nach außen hin offen sind und in die die Bürstenleisten 10 eingelegt werden können. Zusammen mit den Bürstenleisten 10 sind noch Bürstenstützfedern 29 in die Aufnahmeschlitze 17 einlegbar zur Abstützung der Borsten 9 der Bürstenleisten 10. Am Grund 18 der Aufnahmeschlitze 17 ist in einer entsprechenden Gewindebohrung eine Schraube 20 vorgesehen. Eine weitere Schraube 21 ist in einer entsprechenden Gewindebohrung am Schenkel 19 der Aufnahmeschlitze 17 vorgesehen.In a suitable distribution, brush strip carriers 11 are located on the shaft 8, which are connected to the shaft 8 in a rotationally fixed manner and have disk-shaped receiving elements 16. The disk-shaped receiving elements 16 have, in the circumferential direction in a uniform distribution, receiving slots 17 which are open radially outward and into which the brush strips 10 can be inserted. Together with the brush strips 10, brush support springs 29 can also be inserted into the receiving slots 17 to support the bristles 9 of the brush strips 10. At the bottom 18 of the receiving slots 17, a screw 20 is provided in a corresponding threaded hole. Another screw 21 is provided in a corresponding threaded bore on the leg 19 of the receiving slots 17.

In einer Bohrung der Behälterwand 6 ist ein Flansch 32 angeordnet, der seinerseits eine Bohrung 13 aufweist. Ein Lagerauge 7 ist mit einer Lagerfläche 15 drehbar in dieser Bohrung 13 angeordnet. Das Lagerauge 7 weist eine weitere innere Lagerfläche 14, in welchem in üblicher Weise ein Wälzlager 33 angeordnet ist zur Aufnahme und Lagerung der Welle 8 auf. Nach außen abgeschlossen wird die Lagerstelle 12 von einem Deckel 22.A flange 32, which in turn has a bore 13, is arranged in a bore in the container wall 6. A bearing eye 7 is rotatably arranged in this bore 13 with a bearing surface 15. The bearing eye 7 has a further inner bearing surface 14, in which a roller bearing 33 is arranged in the usual way for receiving and supporting the shaft 8. The bearing point 12 is closed off from the outside by a cover 22.

Die Lagerfläche 14 und die Lagerfläche 15 sind exzentrisch zueinander angeordnet, wie dies prinzipiell der Darstellung in Figur 6 entnommen werden kann. Eine äußere Umfangsfläche 23 des Lagerauges 7 weist einen zur Bohrung 13 konzentrischen Zahnkranz 24 auf. Der Zahnkranz 24 ist drehfest mit dem Lagerauge 7 verbunden. Das Lagerauge 7 wird umfasst und axial geführt von einem Flansch 25, der an der Behälterwand 6 befestigt ist. Im Flansch 25 ist drehbar ein Ritzel 26 so eingelassen, daß es mit dem Zahnkranz 24 kämmen kann. Im Flansch 25 ist koaxial zur Drehachse des Ritzels 26 eine Schraube 34 drehbar gelagert und in das Ritzel 26 hineingeschraubt. Die Schraube 34 weist einen Kopf mit einem Innensechskant 35 auf, sodaß die Schraube 34 mit Hilfe eines entsprechenden bekannten Schlüssels über den Innensechskant 35 gedreht werden kann. Zur Einstellung einer konkaven oder konvexen (Figur 9 und Figur 8) oder einer sonstigen Durchbiegung der Bürstenleisten 10 werden im Ausführungsbeispiel die Schrauben 20 in die entsprechende Radialposition gebracht und danach die Bürstenleisten 10 in die Aufnahmeschlitze 17 eingelegt und an den Schrauben 20 zur Anlage gebracht und danach von den Schrauben 21 in dieser Lage festgeklemmt. Mit dieser Klemmung ist gleichzeitig zusammen mit jeder Bürstenleiste 10 die zugehörige Borstenstützfeder 29 festgeklemmt.The bearing surface 14 and the bearing surface 15 are arranged eccentrically to one another, as can be seen in principle from the illustration in FIG. 6. An outer peripheral surface 23 of the bearing eye 7 has a ring gear 24 concentric with the bore 13. The ring gear 24 is rotatably connected to the bearing eye 7. The bearing eye 7 is enclosed and axially guided by a flange 25 which is fastened to the container wall 6. A pinion 26 is rotatably embedded in the flange 25 so that it can mesh with the ring gear 24. In the flange 25, a screw 34 is rotatably mounted coaxially to the axis of rotation of the pinion 26 and screwed into the pinion 26. The screw 34 has a head with an internal hexagon 35, so that the screw 34 can be rotated with the aid of a corresponding known key over the internal hexagon 35. To set a concave or convex (Figure 9 and Figure 8) or any other deflection of the brush strips 10, the screws 20 are brought into the corresponding radial position in the exemplary embodiment and then the brush strips 10 are inserted into the receiving slots 17 and brought into contact with the screws 20 and then clamped by the screws 21 in this position. With this clamping, the associated bristle support spring 29 is clamped together with each brush strip 10.

Im Ausführungsbeispiel weisen die Aufnahmeschlitze 17 eine entgegen der Drehrichtung 28 gerichtete Neigung auf, wodurch eine günstige Belastung der Borsten 9 erreicht und ein Zerstoßen und Verhaken der Borsten 9 am Sieb 3 vermieden wird. Zum Austausch der Bürstenleisten 10 ggf. zusammen mit den Borstenstützfedern 29 müssen lediglich die Schrauben 21 der scheibenförmigen Aufnahmeelemente 16 gelöst werden und es kann die jeweilige Bürstenleiste 10 einfach wie in Figur 1 oben dargestellt entnommen werden und gegen eine neue ausgetauscht werden. Es ist auch sinnvoll, die Bürstenleisten 10 gelegentlich zu entnehmen und zu wenden, um die Durchbiegerichtung für die Borsten 9 zu wechseln.In the exemplary embodiment, the receiving slots 17 have an inclination directed against the direction of rotation 28, as a result of which the bristles 9 are subjected to a favorable load and the bristles 9 are not crushed and caught on the sieve 3. To replace the brush strips 10 if necessary together with the bristle support springs 29, only the screws 21 of the disk-shaped receiving elements 16 have to be loosened and the respective brush strip 10 can simply be removed as shown in FIG. 1 above and exchanged for a new one. It is also sensible to occasionally remove and turn the brush strips 10 in order to change the bending direction for the bristles 9.

Eine weitere Einstellmöglichkeit für die Lage und die Größe des Borstendruckes auf das Sieb 3 ist durch das Lagerauge 7 gegeben, dessen Lagerflächen 14 und 15 exzentrisch zueinander angeordnet sind. Durch eine Verdrehung des Lagerauges 7 wird infolge der beschriebenen Exzentrizität eine entsprechende Lageveränderung der Welle 8 und damit des Bürstenleisten 10 erreicht. Um eine solche Verdrehung des Lagerauges 7 durchzuführen, wird zunächst die Klemmschraube 27, mit welcher das Lagerauge 7 festgeklemmt ist, gelöst, sodaß nunmehr das Lagerauge 7 in der Bohrung 13 des Flansches 32 gedreht werden kann. Um die Drehung zu bewirken, wird mit einem bekannten Innensechskantschlüssel über den Innensechskant 35 die Schraube 34 und damit das in Flansch 25 drehbar angeordnete Ritzel 26 gedreht, welches mit dem Zahnkranz 24, der drehfest mit dem Lagerauge 7 verbunden ist, kämmt. Durch die Drehung des Ritzels 26 wird somit eine entsprechende Drehung des Zahnkranzes 24 und damit des Lagerauges 7 bewirkt. Da die Lagerfläche 14 zur Aufnahme des Wälzlagers 33 und über das Wälzlager 33 zur Aufnahme der Welle 8 exzentrisch zur Lagerfläche 15 angeordnet ist, wird durch die beschriebene Drehung des Lagerauges 7 eine entsprechende Verlagerung der Welle 8 erreicht. Ist der Deckel 22 drehfest mit dem Lagerauge 7 verbunden, so kann er gleichzeitig als Indikator für die Größe der Drehbewegung und damit für die Lage der Welle 8 dienen. Ist die gewünschte Einstellung erreicht, so wird die Klemmschraube 27 wieder festgezogen und damit das Lagerauge 7 in der gewünschten Lage fixiert.A further setting option for the position and the size of the bristle pressure on the screen 3 is provided by the bearing eye 7, the bearing surfaces 14 and 15 of which are arranged eccentrically to one another. By rotating the bearing eye 7, a corresponding change in position of the shaft 8 and thus of the brush strips 10 is achieved due to the eccentricity described. In order to carry out such a rotation of the bearing eye 7, the clamping screw 27 with which the bearing eye 7 is clamped is first loosened, so that the bearing eye 7 can now be rotated in the bore 13 of the flange 32. In order to effect the rotation, the screw 34 and thus the pinion 26 rotatably arranged in the flange 25, which meshes with the toothed ring 24, which is non-rotatably connected to the bearing eye 7, is rotated with a known Allen key over the hexagon socket 35. A corresponding rotation of the ring gear 24 and thus of the bearing eye 7 is thus brought about by the rotation of the pinion 26. Since the bearing surface 14 for receiving the roller bearing 33 and via the roller bearing 33 for receiving the shaft 8 is arranged eccentrically to the bearing surface 15, a corresponding displacement of the shaft 8 is achieved by the described rotation of the bearing eye 7. If the cover 22 is connected in a rotationally fixed manner to the bearing eye 7, it can simultaneously serve as an indicator for the size of the rotary movement and thus for the position of the shaft 8. When the desired setting has been reached, the clamping screw 27 is tightened again and the bearing eye 7 is thus fixed in the desired position.

Am antriebsseitigen Ende der Welle 8 kann eine ganz ähnliche Lagerstelle vorgesehen sein. Lediglich der Deckel 22 entfällt, damit die Welle 8 mit einer Antriebseinrichtung verbunden werden kann.A very similar bearing point can be provided at the drive end of the shaft 8. Only the cover 22 is omitted so that the shaft 8 can be connected to a drive device.

Mit einer nach der Erfindung aufgebauten Dosiereinrichtung wird es möglich, eine kontinuierlich in die von den Leitblechen 30 und 31 gebildete Einlaßöffnung einfließende Menge Flock mit einer Verteilungsdichte von gewünschtem Profil durch das Sieb 3 hindurch an das elektrostatische Feld abzugeben. So kann z. B. erreicht werden, daß über die gesamte Breite der Dosiereinrichtung eine pro Flächeneinheit gleichmässige Auftragsdichte erreicht wird (Profil I, Figur 4). Ebenso ist es möglich, beispielsweise im Bereich der seitlichen Enden der Dosiereinrichtung die Menge Flock pro Flächeneinheit zu vergrößern und gleichzeitig in der Mitte die Flockdichte pro Flächeneinheit zu vermindern (Profil II, Figur 5). Auch andere Verteilungen der Flockdichte pro Flächeneinheit sind erzielbar. Gleichzeitig ist die gesamte Dosiereinrichtung trotz ihrer nahezu unbeschränkten Einstellmöglichkeit außerordentlich einfach aufgebaut und daher von jedem eingewiesenen Betriebsschlosser beherrschbar.

With a metering device constructed according to the invention, it becomes possible to deliver a quantity of flock continuously flowing into the inlet opening formed by the guide plates 30 and 31 with a distribution density of the desired profile through the sieve 3 to the electrostatic field. So z. B. can be achieved that a uniform density per unit area is achieved over the entire width of the metering device (profile I, Figure 4). It is also possible, for example, to increase the amount of flock per unit area in the area of the lateral ends of the metering device and at the same time to reduce the flock density per unit area in the middle (profile II, FIG. 5). Other distributions of the flock density per unit area can also be achieved. At the same time, the entire dosing device, despite its almost unlimited setting options, is extremely simple in construction and can therefore be controlled by any trained locksmith.
