Abstract

Doctor blade dosing systems for devices used for coating material webs, particularly paper or paperboard webs, exist that have a doctor blade rod, which serves as a dosing element while being held inside a slot of a doctor blade bed that, in turn, is mounted in a support that can be fastened inside the frame of the system. According to the disclosure, the doctor blade rod has a diameter of less than 25 mm. The doctor blade bed is inserted in removable manner into a slot of the support situated on the face thereof. The ratio of the cross-sectional area (measured in mm<SUP>2</SUP>) of the doctor blade to the diameter (measured in mm) of the doctor blade rod is less than 60 mm, preferably less than 30 mm. The support is made of a plastic material and is shaped like a clamp having at least one rearward extending clamp limb and one joint location, whereby the holding slot that accommodates the doctor blade bed forms the clamp mouth. A tightening tube that presses the slot walls of the holding slot toward one another is placed on a clamp limb.

Die Rakelstangen sind üblicherweise aus Stahl mit einem Durchmesser zwischen 6 mm - 40 mm gefertigt. Da die beim Beschichten von Papier- oder Kartonbahnen üblicherweise als Beschichtungsmaterial verwendeten Pigmentstreichfarben sehr abrasiv sind, ist es zur Erhöhung der Verschleißfestigkeit bekannt, die Rakelstangen an ihrer Oberfläche mit verschleißfesten Materialien zu beschichten. Je nach Anwendungsfall werden Rakelstangen mit glatter Mantelfläche oder Rakelstangen mit Umfangsrillen eingesetzt. Bei Rakelstangen mit glatter Mantelfläche stellt sich im Betrieb ein geringer Spalt zu der zu beschichtenden Bahn ein, durch den das Beschichtungsmaterial in der gewünschten Menge durchtritt. Rakelstangen mit Umfangsrillen liegen beim Dosieren an der Bahn oder Walze an. Das verbleibende Strichgewicht wird primär durch den Rillenquerschnitt bestimmt, durch den das Beschichtungsmaterial durchtreten kann.The doctor blades are usually made of steel with a diameter between 6 mm - 40 mm. Since the pigment coating inks usually used as coating material when coating paper or cardboard webs are very abrasive, it is known to increase the wear resistance to coat the doctor rods on their surface with wear-resistant materials. Depending on the application, doctor rods with a smooth outer surface or doctor rods with circumferential grooves are used. In the case of squeegee bars with a smooth outer surface, a small gap to the web to be coated is established during operation, through which the coating material passes in the desired amount. Squeegee bars with circumferential grooves lie against the web or roller during metering. The remaining coat weight is primarily determined by the groove cross-section through which the coating material can pass.

Rakelbetten mit exakten Maßen gefertigt werden. Da die Rakelbetten einen relativ großen Querschnitt aufweisen, werden sie zum Erreichen der erforderlichen Maßgenauigkeit in einem Gießverfahren hergestellt und/oder die geforderte Maßgenauigkeit wird durch spanende Bearbeitung erreicht. Die Herstellung ist somit sowohl material- als auch fertigungsintensiv.Doctor beds are made with exact dimensions. Since the doctor beds have a relatively large cross section, they are produced in a casting process in order to achieve the required dimensional accuracy and / or the required dimensional accuracy is achieved by machining. The production is therefore both material and manufacturing intensive.
Die sich im Betrieb drehende Rakelstange bewirkt einen erheblichen Verschleiß des Rakelbettes. Die material- und fertigungsintensiven Rakelbetten müssen daher in regelmäßigen Intervallen ausgetauscht werden. Der Austausch verursacht erhebliche Kosten. Um die durch den Verschleiß bedingtenThe doctor rod rotating during operation causes considerable wear on the doctor bed. The material and manufacturing intensive doctor beds therefore have to be replaced at regular intervals. The exchange causes considerable costs. To those caused by wear

Das Rakelbett ist als möglichst kleines Verschleißteil ausgeführt.To reduce replacement costs without affecting the quality of the coating, the roller doctor metering system according to German patent application 10045515 has a holder with a groove into which the doctor bed is inserted can be used with the inserted doctor rod. The doctor bed is designed to be as small a wear part as possible.

Nach der Erfindung wird das Rakelbett als möglichst kleines Verschleißteil ausgeführt, es benötigt somit weniger Material als die bekannten Rakelbetten. Der geringere Materialeinsatz erlaubt auch die Verwendung hochwertiger - also teurer - Werkstoffe, die eine höhere Standzeit beim Beschichten ermöglichen. Der Halter ist kein Verschleißteil. Er kann somit aufwendiger, beispielsweise durch spanende Bearbeitung, hergestellt werden. Er kann so gestaltet werden, dass er universell einsetzbar ist und unterschiedliche Rakelbetten für Rakelstangen mit unterschiedlichem Durchmesser aufnehmen kann. Weiterhin ermöglicht die Aufteilung des Haltesystems für die -Rakelstange in zwei Teile, nämlich Rakelbett und Halter, den Einsatz verschiedener Werkstoffkombinationen, um das Betriebsverhalten des Dosiersystems zu verbessern. So kann das Rakelbett besonders elastisch für ein verbessertes Dichtverhalten gegenüber der Rakelstange und besonders verschleißfest gestaltet werden, während der Halter aus einem härteren Material gefertigt ist, damit seine erhöhte Steifigkeit Vibrationen des Dosiersystems verhindert.According to the invention, the doctor bed is designed as the smallest possible wear part, it therefore requires less material than the known doctor beds. The lower use of materials also allows the use of high-quality - i.e. more expensive - materials, which enable a longer service life when coating. The holder is not a wearing part. It can thus be produced in a more complex manner, for example by machining. It can be designed so that it can be used universally and can accommodate different doctor beds for doctor bars with different diameters. Furthermore, the division of the holding system for the doctor rod into two parts, namely doctor bed and holder, enables the use of different material combinations in order to improve the operating behavior of the metering system. The doctor bed can be designed to be particularly elastic for improved sealing behavior with respect to the doctor rod and particularly wear-resistant while the holder is made of a harder material so that its increased rigidity prevents vibrations of the dosing system.
Die Gestaltung des Halters nach Art einer Klammer mit einem Druckschlauch, der gegen einen Klammerschenkel und so die Nutwände der Halternut gegeneinander drückt, ermöglicht es, die Nut des Halters für einen Wechsel des Rakelbettes zu durch eine Druckabsenkung im Klemmschlauch zu entspannen. Beim Betrieb des Dosiersystems steht der Klemmschlauch unter Druck, um das Rakelbett mit der eingelegten Rakelstange festzuhalten.The design of the holder in the manner of a clamp with a pressure hose, which presses against a clamp leg and thus the groove walls of the holder groove against one another, makes it possible to relax the groove of the holder for changing the doctor bed by reducing the pressure in the clamping hose. When the metering system is in operation, the clamping hose is under pressure to hold the squeegee bed with the inserted squeegee rod.
Die erfindungsgemäße Ausgestaltung des Dosiersystems hat den weiteren Vorteil, dass sich über den Druck im Klemmschlauch die Spannung regulieren läßt, mit der die Rakelstange im Rakelbett gehalten wird. Die von der Spannung abhängige Reibung der Rakelstange bei ihrer Drehung im Rakelbett läßt sich somit auf möglichst geringe Werte einstellen. Bei sehr breiten (>10 m) Beschichtungsvorrichtungen lassen sich so Rakelstangen mit geringem Durchmesser (10 mm - 12 mm) einsetzen, die an den Enden angetrieben sind, ohne dass die Torsionskräfte zu groß werden. Weiterhin können störende Vibrationen der Rakelstange beim Betrieb verhindert werden, indem die Dämpfung des Systems über den Druck im Klemmschlauch geändert wird. Mit dem Klemmschlauch weist das System vorteilhaft ein zusätzliches Stellglied auf, mit dem das Betriebsverhalten mit dem Schlauchdruck als Stellgröße positiv beeinflußt werden kann.The configuration of the metering system according to the invention has the further advantage that the tension in the clamping tube can be used to regulate the tension with which the doctor rod is held in the doctor bed. The friction, dependent on the tension, of the doctor rod when it rotates in the doctor bed can thus be set to the lowest possible values. In the case of very wide (> 10 m) coating devices, doctor rods with a small diameter (10 mm - 12 mm) can be used, which are driven at the ends without the torsional forces being too great. Furthermore, disturbing vibrations of the doctor rod during operation can be prevented by changing the damping of the system via the pressure in the clamping hose. With the clamping hose, the system advantageously has an additional actuator with which the operating behavior can be positively influenced with the hose pressure as a manipulated variable.

Das in den Figuren dargestellte Dosiersystem ist Teil einer Vorrichtung zum Beschichten einer Papier- oder Kartonbahn 1 mit Streichfarbe. Es ist bevorzugt ein sogenanntes Rollschaber-System, bei dem die Bahn 1 im Bereich des Dosiersystems von einer Gegenwalze 2 abgestützt wird. Ebenso kann das Rakel- Dosiersystem zum indirekten Dosieren eingesetzt werden, bei dem ein vordosierter Film von Beschichtungsmaterial zunächst auf eine Walze aufgetragen und anschließend von dieser an die Bahn abgegeben wird. Eine weitere Einsatzmöglichkeit besteht bei sogenannten Rollrakel-Systemen, bei denen die Bahn in einem freien Abschnitt ohne Abstützung durch eine Walze über die Rakelstange geführt wird.The dosing system shown in the figures is part of a device for coating a paper or cardboard web 1 with coating color. It is preferably a so-called roller scraper system in which the web 1 is supported in the area of the metering system by a counter roller 2. The doctor blade metering system can also be used for indirect metering, in which a pre-metered film of coating material is first applied to a roller and then released by the latter onto the web. Another application is in so-called roller doctor systems, in which the web is guided over the doctor rod in a free section without support from a roller.
In Drehrichtung der Walze 2 vor dem Dosiersystem ist ein bekanntes Auftragssystem (Düsenauftragwerk, Walzenauftragwerk etc.) angeordnet, von dem Streichfarbe im Überschuss auf die Bahn 1 aufgetragen wird.In the direction of rotation of the roller 2 in front of the metering system, a known application system (nozzle applicator, roller applicator, etc.) is arranged, of which coating color is applied in excess to the web 1.
Das Rakel-Dosiersystem enthält als Dosierelement eine Rakelstange 3, die in einem zur Bahn 1 hin teilweise offenen Rakelbett 4 mittels eines Drehantriebs drehbar gelagert ist. Die Mantelfläche der Rakelstange 3 ist entweder glatt oder mit Umfangsrillen versehen. Ihr Durchmesser beträgt 6mm- 25 mm. Bevorzugte Durchmesser sind 9,75 mm, 10,00 mm, 12,00 mm, 12,7 mm, 13,65 mm, 15,00 mm, 15,87 mm und 16,00 mm. Die axiale Länge der Rakelstange 3 entspricht der Arbeitsbreite der Beschichtungsvorrichtung, die bis zu 10 m betragen kann. Bevorzugt ist die Rakelstange aus Edelstahl gefertigt und ihre Mantelfläche ist verschleißfest beschichtet, beispielsweise verchromt oder mit Keramik beschichtet. Das Rakelbett 4 ist vorzugsweise aus einem zumindest begrenzt elastischen Material gefertigt. Nach einer Ausführungsform ist es aus einem Elastomer ( Gummi oder Kunststoff) gefertigt, vorzugsweise aus Polyurethan. Die Härte des Materials aus dem das Rakelbett 4 gefertigt ist, beträgt dann 50 Shore A bis 65 Shore D, vorzugsweise zwischen 85 Shore A und 95 Shore A. Das Material ist somit relativ elastisch, so dass sich das Bett 4 dichtend an die Rakelstange 3 anlegen kann, um ein Eindringen von Streichfarbe in das Bett 4 zu verhindern. Auf bekannte Weise weist das Rakelbett 4 eine Nut 18 auf, in die die Rakelstange 3 eingelegt wird, wobei das Rakelbett 4 die Rakelstange 3 in einem Winkelbereich von zumindest 180° umfaßt, damit die Rakelstange 3 sicher gehalten wird.The doctor blade metering system contains as a metering element a doctor rod 3 which is rotatably mounted in a doctor bed 4 which is partially open towards the web 1 by means of a rotary drive. The outer surface of the doctor rod 3 is either smooth or provided with circumferential grooves. Their diameter is 6mm- 25mm. Preferred diameters are 9.75 mm, 10.00 mm, 12.00 mm, 12.7 mm, 13.65 mm, 15.00 mm, 15.87 mm and 16.00 mm. The axial length of the doctor rod 3 corresponds to the working width of the coating device, which can be up to 10 m. The doctor rod is preferably made of stainless steel and its outer surface is coated to be wear-resistant, for example chrome-plated or coated with ceramic. The doctor bed 4 is preferably made of an at least limited elastic material. According to one embodiment, it is made of an elastomer (rubber or plastic), preferably of polyurethane. The hardness of the material from which the doctor bed 4 is made is then 50 Shore A to 65 Shore D, preferably between 85 Shore A and 95 Shore A. The material is therefore relatively elastic, so that the bed 4 seals against the doctor rod 3 can create to prevent penetration of coating color into the bed 4. In a known manner, the doctor bed 4 has a groove 18 into which the doctor rod 3 is inserted, the doctor bed 4 enclosing the doctor rod 3 in an angular range of at least 180 ° so that the doctor rod 3 is held securely.
Alternativ ist es auch möglich, das Rakelbett 4 aus Polyäthylen zu fertigen. Die Bearbeitung auf die geforderte Maßgenauigkeit erfolgt dann in einem spanenden Verfahren, insbesondere durch Fräsen.Alternatively, it is also possible to manufacture the doctor bed 4 from polyethylene. The machining to the required dimensional accuracy is then carried out in a machining process, in particular by milling.
Das Verhältnis der Querschnittsfläche (in mm2 gemessen) des Rakelbetts (4) zum Durchmesser (in mm gemessen) der Rakelstange (3) beträgt weniger als 60 mm, bevorzugt weniger als 30 mm. Bevorzugt beträgt das Verhältnis der Querschnittsfläche des Rakelbetts (4) zum Durchmesser der Rakelstange (3) 10 mm bis 25 mm.The ratio of the cross-sectional area (measured in mm 2 ) of the doctor bed (4) to the diameter (measured in mm) of the doctor rod (3) is less than 60 mm, preferably less than 30 mm. The ratio of the cross-sectional area of the doctor bed (4) to the diameter of the doctor rod (3) is preferably 10 mm to 25 mm.
Als besonders vorteilhaft hat sich eine Rakelstange mit einem Durchmesser kleiner/gleich 16 mm gezeigt, die in ein Rakelbett 4 mit einer Querschnittsfläche von 100 - 400 mm2 eingelegt ist. Das Rakelbett 4 ist über die Arbeitsbreite der Beschichtungsvorrichtung, also die Länge der Rakelstange 3 mit gleichbleibendem Querschnitt ausgestaltet. In das Rakelbett 4 ist zumindest ein zur Rakelstange 3 hin offener Kanal 5 eingearbeitet, in den während des Betriebes Wasser als Schmier- und Reinigungsmittel eingeleitet wird.A doctor rod with a diameter of less than or equal to 16 mm, which is inserted into a doctor bed 4 with a cross-sectional area of 100-400 mm 2, has proven to be particularly advantageous. The doctor bed 4 is designed with the same cross section over the working width of the coating device, that is to say the length of the doctor rod 3. In the doctor bed 4 at least one channel 5 open to the doctor rod 3 is incorporated, into which water is introduced as a lubricant and cleaning agent during operation.
Das Rakelbett 4 ist in einer zur Bahn 1 hin offenen Nut 18 eines Halters 6 herausnehmbar eingesetzt, wie in Figur 3 besonders deutlich dargestellt ist. Die Querschnittsfläche der Nut 18 ist der äußeren Kontur des Rakelbettes 4 angepaßt, so dass dieses sicher durch Reib- oder Formschluss gehalten wird. Bevorzugt wird die Öffnung der Nut 18 des Halters 6 von zumindest einem Vorsprung 19 , bevorzugt von zwei Vorsprüngen 19, begrenzt, und das Rakelbett 4 weist eine entsprechende Anzahl (in den Ausführungsbeispielen zwei) angepaßt geformte Verbreiterungen 20 auf, die beim Einsetzen des Rakelbettes 4 in den Halter 6 hinter den Vorsprung 19 oder die Vorsprünge 19 bewegt werden, so dass das Rakelbett 4 nach dem Einsetzen in den Halter 6 formschlüssig in diesem festgeklemmt ist.The doctor bed 4 is removably inserted in a groove 18 of a holder 6 which is open towards the web 1, as is particularly clearly shown in FIG. The cross-sectional area of the groove 18 is adapted to the outer contour of the doctor bed 4, so that it is held securely by friction or positive locking. Prefers the opening of the groove 18 of the holder 6 is delimited by at least one projection 19, preferably by two projections 19, and the doctor bed 4 has a corresponding number (two in the exemplary embodiments) of shaped widenings 20 which are formed when the doctor bed 4 is inserted the holder 6 is moved behind the projection 19 or the projections 19, so that the doctor bed 4 is positively clamped in the holder 6 after insertion.
Der Halter 6 ist aus einem Kunstoffmaterial, beispielsweise aus Polyäthylen oder Polyurethan gefertigt. Die Härte des Materials beträgt 50 Shore A bis 65 Shore D. Er ist nach Art einer Klammer mit zumindest einem sich nach hinten erstreckenden Klammerschenkel 13, und einer Gelenkstelle 15 gestaltet. Die das Rakelbett 4 aufnehmende Halternut 18 bildet das Klammermaul. An der Rückseite des Halters 6 ist an einem Klammerschenkel 13 ein die Nutwande der Halternut 18 gegeneinander drückender Klemmschlauch 16 angeordnet, der mit Druckluft beaufschlagbar ist.The holder 6 is made of a plastic material, for example of polyethylene or polyurethane. The hardness of the material is 50 Shore A to 65 Shore D. It is designed in the manner of a clip with at least one clip leg 13 extending to the rear and a joint point 15. The holder groove 18 receiving the doctor bed 4 forms the clamp mouth. On the rear of the holder 6, a clamping hose 16, which presses the groove walls of the holder groove 18 against one another, is arranged on a clamp leg 13 and can be pressurized with compressed air.
Bei der. Ausführungsform nach Figur 1 ist der Halter 6 mit zwei sich nach hinten erstreckenden Klammerschenkeln 13, 14 gestaltet. Der Klemmschlauch 16 ist zwischen den beiden Klammerschenkeln 13,14 angeordnet .In the. Embodiment according to Figure 1, the holder 6 is designed with two rearwardly extending bracket legs 13, 14. The clamping hose 16 is arranged between the two clamp legs 13, 14.
Bei der Ausführungsform nach den Figuren 2 und 3 enthält der Halter 6 nur einen Klammerschenkel 13. Der Klemmschlauch 16 stützt sich auf dem Hauptteil des Halters 6 ab, in den die Nut 18 eingearbeitet ist, Er drückt den Klammerschenkel 13 zum Einspannen des Rakelbetts 3 nach oben und damit die obere Nutwand der Halternut 18 nach unten.In the embodiment according to FIGS. 2 and 3, the holder 6 contains only one clamp leg 13. The clamping hose 16 is supported on the main part of the holder 6, into which the groove 18 is incorporated. It presses the clamp leg 13 to clamp the doctor bed 3 above and thus the upper groove wall of the holder groove 18 downwards.
Bevorzugt ist als Gelenkstelle 15 ein Bereich des Halters 6 zwischen dem Klemmschlauch 16 und der Halternut 18 als Schwachstelle mit verminderter Dicke ausgebildet. Bei der Ausführungsform nach Figur 1 ist dazu ein Schlitz 17 in den Halter 6 eingearbeitet, der sich vom Bereich des Klemmschlauchs 16 in Richtung zur Halternut 18 erstreckt. Bei der Ausführungsform nach den Figuren 2 und 3 ist der Halter 6 im Bereich zwischen der Halternut 18 und dem Klemmschlauch 16 entsprechend dünn ausgestaltet. Die radial zur Rakelstange 3 in Richtung zum Klemmschlauch 16 gemessene Dicke des Halters 6 an der Schwachstelle - in Figur 1 der Abstand zwischen dem Schlitz 17 und dem Rakelbett 4 - beträgt 0,5 mm bis 10 mm, bevorzugt 1 mm bis 3 mm. Dies gewährleistet eine ausreichende Elastizität der Klammerschenkel 13,14.A region of the holder 6 between the clamping hose 16 and the holder groove 18 is preferably designed as a weak point with a reduced thickness as the articulation point 15. In the embodiment according to FIG. 1, a slot 17 is incorporated into the holder 6, which extends from the region of the clamping hose 16 in the direction of the holder groove 18. In the embodiment according to FIGS. 2 and 3, the holder 6 is in the region between the holder groove 18 and the clamping hose 16 designed accordingly thin. The thickness of the holder 6 at the weak point, measured radially to the doctor rod 3 in the direction of the clamping tube 16 - in FIG. 1 the distance between the slot 17 and the doctor bed 4 - is 0.5 mm to 10 mm, preferably 1 mm to 3 mm. This ensures sufficient elasticity of the clamp legs 13, 14.
Der Halter 6 ist auf bekannte Weise mit seinem Fuß 8 an einem Tragbalken 7 als Teil des Rahmens des Dosiersystems lösbar befestigt. Im Ausführungsbeispiel nach Figur 1 wird der Halters 6 mit einem drehbaren Klemmelement 9 festgeklemmt, das sich quer über die Arbeitsbreite der Beschichtungsvorrichtung erstreckend in einer zum Fuß 8 hin offenen Nut eines abgewinkelten Lagerteils 10 angeordnet ist, das auf den Tragbalken 7 festgeschraubt ist. Im Ausführungsbeispiel nach den Figuren 2 und 3 ist verbreitert sich der Fuß 8 zu einem Befestigungsteil 21 , das mittels Schrauben 22 an dem Tragbalken 7 festgeschraubt ist.The holder 6 is fixed in a known manner with its foot 8 on a support beam 7 as part of the frame of the metering system. In the exemplary embodiment according to FIG. 1, the holder 6 is clamped with a rotatable clamping element 9 which extends across the working width of the coating device in a groove of an angled bearing part 10 which is open towards the foot 8 and which is screwed onto the support beam 7. In the exemplary embodiment according to FIGS. 2 and 3, the foot 8 widens to form a fastening part 21 which is screwed onto the support beam 7 by means of screws 22.
An der Rückseite des Halters 6 ist ein sich am Rahmen des Systems abstützender und den Halter 6 in Richtung zum Rakelbett 4 drückender Druckschlauch 12 angeordnet, der sich quer über die Länge des Halters 6 erstreckt. Der Druckschlauch 12 stützt sich am Rahmen des Systems ab und drückt an der Rückseite des Halters 6 diesen mit dem Rakelbett 4 und der Rakelstange 3 Richtung zur zu beschichtenden Bahn 1 oder Walze, um den gewünschten Anpressdruck der Rakelstange 4 gegen die Bahn 1 oder Walze aufzubauen. Damit dies möglich ist, ist der Fuß 8 des Halters 6 in einem Bereich begrenzt elastisch gestaltet. In den Ausführungsbeispielen wird die Elastizität durch einen dünneren Querschnitt zwischen der Befestigungsstelle an dem Lagerteil 10 und dem Hauptteil mit der Halternut 18 bewirkt.A pressure hose 12, which is supported on the frame of the system and presses the holder 6 in the direction of the doctor bed 4, is arranged on the back of the holder and extends across the length of the holder 6. The pressure hose 12 is supported on the frame of the system and presses it on the back of the holder 6 with the doctor bed 4 and the doctor rod 3 in the direction of the web 1 or roller to be coated, in order to build up the desired contact pressure of the doctor rod 4 against the web 1 or roller , So that this is possible, the foot 8 of the holder 6 is designed to be of limited elasticity in one area. In the exemplary embodiments, the elasticity is brought about by a thinner cross section between the fastening point on the bearing part 10 and the main part with the holder groove 18.
Bei der Ausführungsform nach Figur 1 ist der Druckschlauch 12 oben am senkrechten Teil des Lagerteils 10 befestigt, bei der Ausführungsform nach FigurIn the embodiment according to FIG. 1, the pressure hose 12 is attached at the top to the vertical part of the bearing part 10, in the embodiment according to FIG
2 und 3 an der Rückseite des Halters 6. Das Rakelbett 4 mit der eingelegten Rakelstange 3 wird bei Betriebsstillstand in die Nut 18 des Halters 6 eingesetzt, während der Klemmschlauch 16 drucklos ist. Wie in Figur 3 dargestellt, ist der Klammerschenkel 13 so vorgespannt, dass sich die Nut 18 ohne Druck im Klemmschlauch 16 selbsttätig etwas öffnet. Nach dem Einsetzen des Rakelbetts 4 wird Druckluft in den Klemmschlauch 16 eingeleitet. Dadurch werden die Nutwände des Halters 6 gegeneinander gedrückt, und das Rakelbett 4 mit der Rakelstange 3 wird im Halter 6 fixiert. Der Druck wird dabei so gewählt, daß einerseits ein sicherer Halt des Bettes 4 und der Stange 3 gewährleistet ist, andererseits die Reibung der Rakelstange 3 ausreichend gering ist. Falls Vibrationen beim Betrieb auftreten, wird der Druck zur Dämpfung variiert. 2 and 3 on the back of the holder 6. The squeegee bed 4 with the inserted squeegee rod 3 is inserted into the groove 18 of the holder 6 when the machine is at a standstill, while the clamping hose 16 is depressurized. As shown in FIG. 3, the clamp leg 13 is prestressed in such a way that the groove 18 opens automatically somewhat without pressure in the clamping hose 16. After inserting the doctor bed 4, compressed air is introduced into the clamping tube 16. As a result, the groove walls of the holder 6 are pressed against one another, and the doctor bed 4 with the doctor rod 3 is fixed in the holder 6. The pressure is chosen so that on the one hand a secure hold of the bed 4 and the rod 3 is ensured, on the other hand the friction of the doctor rod 3 is sufficiently low. If vibrations occur during operation, the pressure for damping is varied.
