Wird mit Hilfe der vier Walzen 10, 15, 23 und 32 gearbeitet, so nehmen die Walzen die in ausgezogener Linie wiedergegebene Stellung ein, und der Beschichtungsstoff wird in den Zwickel 38 zeischen den Walzen 23 und 32 aufgegeben. Hierzu ist die Anordnung der Wälzen 23 und 32 so getroffen, daß der Walzenzwickel 38 in der Drehrichtung der Walze 23 hinter der senkrechten Mittelebene 40 der Dosierwalze 23 gelegen ist. Vorzugsweise ist die Achse 41 der Walze 32 in einem oberen Winkelbereich bis zu 45° in Drehrichtung der Dosierwalze 23 hinterder Mittelebene 40 gelegen, wie dies die Zeichnung verdeutlicht. Die Walze 32 ist angetrieben und wird in Richtung des Pfeiles 39 oder entgegengesetzt hierzu in Drehrichtung versetzt, wobei eine nicht dargestellte Rakel Anwendung findet.If the four rollers 10, 15, 23 and 32 are used, the rollers assume the position shown in the solid line, and the coating material is fed into the interstices 38 between the rollers 23 and 32. For this purpose, the arrangement of the rollers 23 and 32 is such that the roller winding 38 is located behind the vertical central plane 40 of the metering roller 23 in the direction of rotation of the roller 23. Preferably, the axis 41 of the roller 32 is at an upper angle rich up to 45 ° in the direction of rotation of the metering roller 23 behind the central plane 40, as the drawing shows. The roller 32 is driven and is displaced in the direction of the arrow 39 or opposite thereto in the direction of rotation, a doctor blade, not shown, being used.

Die Walzenspalte zwischen den Walzen 10 und 15, 15 und 23 können etwa von dem Punkt 42 aus selbst dann beobachtet werden, wenn die Walze 32 an der Walze 23 zur Anlage kommt. Der Walzenzwickel 38 kann etwa von dem Punkt 43 aus gut beobachtet werden. Bei abgehobener Walze 32 und Arbeit mit der Tauchwalze 15 in einer Tauchwanne, wobei die Walze 32 die Stellung 32' einnimmt, können die Walzenspalte zwischen den Walzen 10, 15, 23 von oben gut beobachtet werden, ohne daß die Walze 32 die Sicht behindert.The nips between the rollers 10 and 15, 15 and 23 can be observed from about point 42 even when the roller 32 comes into contact with the roller 23. The roller winder 38 can be easily observed from about point 43. When the roller 32 is lifted off and working with the immersion roller 15 in an immersion trough, the roller 32 occupying the position 32 ', the roller nips between the rollers 10, 15, 23 can be observed well from above without the roller 32 obstructing the view.

Bei gleichmäßigem Abstand aller Walzen 10, 15, 23 und 32 von einer gemeinsamen Linie 44 kann auf dieser eine Welle 45 bewegt werden (Fig. 3), auf deren vorderen Ende die koaxial auf dieser Welle drehfest, aber bei Längsverschieben abnehmbar aufgebrachte Reinigungswalze 37 angeordnet ist. Die Welle 45 kann über ein Riemengetriebe 46 oder auf irgendeine andere geeignete Art und Weise durch einen Motor 47 in Drehung versetzt werden, was durch den Pfeil 48 symbolisiert wird.- Die Welle 45 ist in einem Arm 49 gelagert, der vorzugsweise abgekrümmt ist und die Abschnitte 50, 51 aufweist, wobei der letztgenannte an einer Zahnstange 52 angeordnet ist, die parallel zu der Linie 44 gelegen ist, die mit der Mittelachse der Welle 45 und der Achse 37a der Reinigungswalze oder -bürste zusammenfällt, bewegbar ist. Hierzu kann mit der Verzahnung 53 der Zahnstange 52 ein Ritzel 54 kämmen, das durch einen Motor 55 angetrieben wird, wodurch der Arm 49 und die Reinigungswalze oder -bürste 37 eine hin- und hergehende Bewegung in Richtung des Pfeiles 56 erfahren kann.If all the rollers 10, 15, 23 and 32 are evenly spaced from a common line 44, a shaft 45 can be moved on this (FIG. 3), on the front end of which the cleaning roller 37, which is coaxially fixed on the shaft but can be removed during longitudinal displacement, is arranged is. The shaft 45 can be set in rotation by means of a belt transmission 46 or in any other suitable manner by a motor 47, which is symbolized by the arrow 48. The shaft 45 is mounted in an arm 49, which is preferably curved and which Has sections 50, 51, the latter being arranged on a rack 52 which is parallel to the line 44, which coincides with the central axis of the shaft 45 and the axis 37a of the cleaning roller or brush, is movable. For this purpose, a toothing 54 of the rack 52 can mesh with a pinion 54 which is driven by a motor 55, as a result of which the arm 49 and the cleaning roller or brush 37 can experience a reciprocating movement in the direction of the arrow 56.

Die Reinigungswalze oder -bürste 37 ist vorzugsweise erheblich kürzer als die Beschichtungswalzen 10, 15, 23 und 32. Sie besteht aus einer inneren Traghülse 57 (Fig. 4), an der in bekannter Weise radial nach außen gerichtete Teile 58 einer Bürste 59 angeordnet sind. Um die freien Enden 60 der Bürste 59 ist eine Flüssigkeit aufnehmende, saugfähige Lage, vorzugsweise ein textiler Überzug 61 aufgebracht. Dieser ist von der Bürste 59 leicht abnehmbar und kann in geeigneter Weise auf der Bürste gehalten werden, so daß sich die Bürste oder Walze 37 in Richtung des Pfeiles 48 mit der Welle 45 zu drehen vermag. Hierzu ist die Hülse 57 mit einer Längsnut 62 versehen und über Feder und Nut 63, 64 mit einem verjüngten Abschnitt 65 der Welle 45 verbunden, wodurch eine Anlageschulter 66 gebildet wird. Die derart drehfest mit der Welle 45 verbundende Bürste oder Walze 37 kann durch ein irgendwie geeignetes Mittel in Längsrichtung auf dem Abschnitt 65 der Welle 45 lösbar gehalten sein.Hierzu kann beispielsweise ein selbsthemmender Keil 67 dienen, der in einen entsprechenden Schlitz 68 des Abschnitts 65 einschiebbar ist.The cleaning roller or brush 37 is preferably considerably shorter than the coating rollers 10, 15, 23 and 32. It consists of an inner support sleeve 57 (FIG. 4) on which, in a known manner, parts 58 of a brush 59 which are directed radially outwards are arranged . A liquid absorbent layer, preferably a textile covering 61, is applied around the free ends 60 of the brush 59. This is easily removable from the brush 59 and can be held in a suitable manner on the brush, so that the brush or roller 37 is able to rotate in the direction of arrow 48 with the shaft 45. For this purpose, the sleeve 57 is provided with a longitudinal groove 62 and connected via spring and groove 63, 64 to a tapered section 65 of the shaft 45, as a result of which an abutment shoulder 66 is formed. The brush or roller 37 connected in this manner in a rotationally fixed manner to the shaft 45 can be detachably held in the longitudinal direction on the section 65 of the shaft 45 by any suitable means. For this purpose, for example, a self-locking wedge 67 can be used, which can be inserted into a corresponding slot 68 of the section 65 is.

Die Reinigungsvorrichtung befindet sich mit ihrem Arm 49 und der Bürste oder Walze 37 zunächst in ihrer in Fig. 2 in ausgezogener Linie gezeigten Ausgangsstellung seitlich der Walzen 10, 15, 23, 32.- Nachdem die Walzen 10, 15, und 23 geringfügig voneinander und von dem bandförmigen Gut G auf der Walze 2 abgehoben wurden und die Walze 32 ihre Lage 32' erreicht hat, fährt der Arm 45 mit der kurzen Reinigungsbürste oder-walze 37 unter Drehen sowohl der Walzen 10, 15, 23 und 32 wie auch der Reinigungsbürste oder -walze 37 selbst in Pfeilrichtung 69 zwischen die Beschichtungswalzen 10, 15, 23, 32. Hierbei werden diese Walzen durch die Reinigungsbürste oder -walze 37 mit ihrer Lösungsflüssigkeit in dem saugfähigen Textilüberzug 61 intensiv gereinigt. Nachdem die Reinigungswalze 12 die Stellung 37' in Fig. 2 erreicht hat, wird ein der Walze in ihrer Krümmung angepaßter Sattel oder Aufnahmetisch 70, der zunächst in einer abgesenkten Lage verharrte, durch die Kolbenstange 71 eines nicht dargestellten Zylinder-Kolben-Aggregats bis zur Anlage an der Bürste oder Walze 37 in deren Stellung 37' angehoben. Hieraufhin wird das Verbindungsmittel, beispielsweise der Keil 67 in Fig. 3, gelöst und die Welle 45 mit ihrem Abschnitt 65 entgegengesetzt zur Richtung des Pfeiles 69 in die Ausgangslage nach Fig. 3 zurückgebracht. Die verunreinigte Reinigungsbürste oder -walze ruht nunmehr auf dem Sattel oder Tisch 70; sie kann von diesem abgenommen und von dem verunreinigten Überzug 61 befreit werden. Nach Auflegen eines neuen Überzuges und Tränken desselben mit Reinigungsflüssigkeit kann die neue Bürste oder Walze 37 auf die Welle 45 bzw. deren verjüngten Abschnitt 65 drehfest angebracht und gegen Längsverschieben durch den Keil 67 gesichert werden, falls die Bürste oder Walze 37 nicht bereits vor dem Aufbringen und Tränken des Überzuges auf die Welle 45 aufgesteckt wurde.The cleaning device with its arm 49 and the brush or roller 37 is initially in its starting position shown in solid line in FIG. 2, to the side of the rollers 10, 15, 23, 32. After the rollers 10, 15, and 23 are slightly apart and have been lifted from the band-shaped material G on the roller 2 and the roller 32 has reached its position 32 ', the arm 45 moves with the short cleaning brush or roller 37 while rotating the rollers 10, 15, 23 and 32 as well as the cleaning brush or roller 37 itself in the direction of arrow 69 between the coating rollers 10, 15, 23, 32. Here, these rollers are cleaned intensively by the cleaning brush or roller 37 with its solvent liquid in the absorbent textile cover 61. After the cleaning roller 12 has reached the position 37 'in FIG. 2, a saddle or receiving table 70 which is adapted to the roller in its curvature and which initially remained in a lowered position is moved through the piston rod 71 of a cylinder-piston unit (not shown) to System on the brush or roller 37 raised in its position 37 '. The connecting means, for example the wedge 67 in FIG. 3, is then released and the shaft 45 with its section 65 opposite to the direction of the arrow 69 is returned to the starting position according to FIG. 3. The contaminated cleaning brush or roller now rests on the saddle or table 70; it can be removed from it and freed from the contaminated coating 61. After putting on a new coating and soaking it with cleaning liquid, the new brush or Roller 37 is attached to shaft 45 or its tapered section 65 in a rotationally fixed manner and secured against longitudinal displacement by wedge 67 if brush or roller 37 has not already been attached to shaft 45 before the coating is applied and soaked.

Abweichend von der dargestellten Ausführungsform ist es möglich, den Arm 51 unbeweglich zu lassen und eine lange fliegende Welle mit daran angeordneter Reinigungsbürste oder -walze von der einen Seite zur anderen Seite der Beschichtungswalzen 10, 15, 23, 32 bewegen zu lassen. Die dargestellte Ausführungsform hat jedoch den Vorteil einer kurzen fliegenden Welle, wobei der Arm 51 in den Zwischenraum 72 zwischen die Walzen 1o und 32 in deren obersten Stellung 32' gefahren werden kann.Deviating from the illustrated embodiment, it is possible to make the arm 51 stationary and a long stub shaft having arranged thereon cleaning brush or roller of the let one side to the other side of the coating rollers 1 0, 15, 23, move 32nd However, the embodiment shown has the advantage of a short flying shaft, the arm 51 being able to be moved into the intermediate space 72 between the rollers 10 and 32 in their uppermost position 32 '.

Um die Reinigungsbürste oder walze 37 von der einen zur anderen Seite der Reinigungswalzen 10, 15, 23, 32 verfahren zu lassen, sind die Lagerböcke 80, 81, 82 und 83 der Walzen 10, 15, 23, 32 derart ausgebildet, (Fig. 2), daß ihr der Reinigungswalze-oder- bürste 37 zugekehrte Abschnitt 84 innerhalb des Umfanges der Walzen 10, 15 23, 32 gelegen ist, so daß die Reinigungswalze oder- bürste 37 frei an diesen Lagerböcken von der einen Seite zur anderen Seite der Walzen 10, 15, 23, 32 bewegt.- Hierbei wird der Vorteil erzielt, daß das Reinigen der Beschichtungswalzen 10, 15, 23, 32 so schnell vorgenommen werden kann, daß es keines Unterbrechens des Laufes des bandförmigen Gutes | G bedarf, um den Beschichtungsstoffwechsel vorzunehmen. Ferner wird eine gute Reinigung dadurch erreicht, daß die Bürste oder Walze 37 zum Reinigen ausschließlich in der Richtung des Pfeiles 69 (Fig. 3) bewegt wird und nach Zurücklegung dieses Weges von der Welle 45 entfernt werden kann, so daß die beschmutzte Reinigungsbürste oder -walze ihren Rückweg nicht mehr über die gereinigten Walzen 10, 15, 23, 32 zu nehmen hat. Während des Reinigungsvorganges selbst d. h. der Arbeit der Walze oder Bürste 37 liegen diese Walzen nicht aneinander.To move the cleaning brush or roller 37 from one side to the other of the cleaning rollers 10, 15, 23, 32, the bearing blocks 80, 81, 82 and 83 of the rollers 10, 15, 23, 32 are designed in such a way (FIG. 2) that the section 84 facing the cleaning roller or brush 37 is located within the circumference of the rollers 10, 15, 23, 32, so that the cleaning roller or brush 37 is free on these bearing blocks from one side to the other side of the rollers 10, 15, 23, 32 moves.- This has the advantage that the cleaning of the coating rollers 10, 15, 23, 32 can be carried out so quickly that there is no interruption of the running of the strip-shaped material | G is required to carry out the coating metabolism. Furthermore, good cleaning is achieved in that the brush or Roller 37 for cleaning is moved exclusively in the direction of arrow 69 (FIG. 3) and can be removed from the shaft 45 after covering this path, so that the soiled cleaning brush or roller no longer travels back via the cleaned rollers 10, 15 , 23, 32 has to take. During the cleaning process itself, ie the work of the roller or brush 37, these rollers are not in contact with one another.

Das Aufsetzen der Reinigungsbürste oder-walze 37 auf die fliegende Welle 45 kann in der vorstehend beschriebenen Weise schnell erfolgen. Selbst bei starker Verunreinigung und bei für die Reinigung ungünstigem Beschichtungsstoff stellt es keine Schwierigkeiten dar, die Bürste oder Walze 37 in ihrer Lage 37' schnell von dem Abschnitt 65 zu lösen, so daß die Welle 45 gegebenenfalls im Schnellgang in ihre Ausgangsposition in Fig. 3 zurückgefahren werden kann.The cleaning brush or roller 37 can be placed quickly on the flying shaft 45 in the manner described above. Even in the case of severe contamination and if the coating material is not suitable for cleaning, there is no difficulty in quickly detaching the brush or roller 37 in its position 37 'from the section 65, so that the shaft 45 can, if necessary, overdrive to its starting position in FIG. 3 can be reduced.

Auf die Befestigungsvorrichtung, d. h. den Keil 67 kann verzichtet werden, da wie aus vorstehendem zu entnehmen ist, die Walze 37 auf der Welle 45 nur in Richtung des Pfeiles 69 sich spiralförmig bewegt, in entgegengesetzter Richtung dagegen die sich nicht drehende Welle 45 ohne die Walze 37 in ihre Ausgangsstellung gezogen wird. Bei der Bewegung in Richtung des Pfeiles 69 wird die Walze 37 stets an der Schulter 66 der Welle 45 gehalten.On the fastener, d. H. the wedge 67 can be dispensed with, since, as can be seen from the foregoing, the roller 37 on the shaft 45 only moves spirally in the direction of the arrow 69, in the opposite direction, however, the non-rotating shaft 45 is pulled into its starting position without the roller 37 becomes. During the movement in the direction of arrow 69, the roller 37 is always held on the shoulder 66 of the shaft 45.

Mit Hilfe eines nicht dargestellten Reinigungsschabers, der von unten an die Walze 15 geschwenkt werden kann und durch den Kontakt der Walzen miteinander wird eine Vorreinigung aller Walzen um ca. 50 - 70 % ihres Verschmutzungsgrades erreicht. Danach werden die Walzen 10, 15, 23 durch Abheben voneinander um einige Millimeter in Reinigungsposition gebracht. Gleichzeitig ist die Walze 38 in Eilgang in die Lage 32' gelangt. IndLesen Reinigungspositionen befinden sich alle Walzen in gleichem Abstand von der Linie 44 und der Drehachse 37a der Reinigungswalze oder -bürste 37.With the help of a cleaning scraper, not shown, the can be pivoted from below to the roller 15 and by the contact of the rollers with each other a pre-cleaning of about 50 - 70% of their degree of contamination is achieved. Then the rollers 10, 15, 23 are brought into a cleaning position by lifting them apart by a few millimeters. At the same time, roller 38 has reached position 32 'in rapid traverse. In the cleaning positions, all the rollers are equidistant from the line 44 and the axis of rotation 37a of the cleaning roller or brush 37.
