Definitions

  • the invention relates to a device for applying an adhesive in the form of transverse gluing to a web, in particular for gluing two very fast-running webs, in rotary printing presses, in which a substantial portion of the jacket of an application cylinder rotating about its axis is separated from the web to be glued looped around and the circumference of the jacket is dimensioned according to the distance of the cross-gluing or a whole multiple thereof, the adhesive being guided from a stationary axial adhesive connection to at least one adhesive supply channel extending along a jacket line, rotating with the application cylinder and being in an insert, from which at least one row of outlet openings in the cylinder wall are supplied with the adhesive in a controlled manner.
  • a cross glue unit with these features can be found in DE-C-32 22 335 as known. Then the cross-gluing of a very fast-running paper or fabric web is initiated with the help of a rotating application cylinder, in the circumference of which there are a large number of adhesive outlet openings along a surface line. The adhesive is discharged through these openings at points. The line bonding results from the summation of these points.
  • the application cylinder Because of the high web speed of the webs to be glued, the application cylinder necessarily has a high rotational speed. This leads to problems when the adhesive emerges from the outlet openings. In order not to allow these centrifugal force-dependent conditions to have an effect, the outlet openings are closed from the inside, specifically when the web to be glued does not cover these outlet openings. On the other hand, the web is guided around the application cylinder in a relatively large wrap angle. During the synchronization of the web and the application cylinder in the area of this wrapping, the outlet openings are released from the inside, so that the adhesive can be guided against the web under the influence of centrifugal force. At standstill, the application cylinder is moved into such a position that sealing rollers can be pressed against the outlet openings from the outside.
  • the invention is therefore based on the object to further develop the known cross-gluing unit so that it can be used without the need for complete exchange for generating different distances between the cross-glues.
  • the invention is not restricted to use in gravure printing technology.
  • the invention even offers the possibility of providing an insert for the use of application cylinders of different diameters, the curved outside of the insert corresponding to the curvature of the smallest application cylinder provided. If such an insert is used in an application cylinder whose diameter is larger than that of the application cylinder originally intended for the application, then there is a step due to the different curvatures of the insert and application cylinder on the edge of the guide, which are accepted in certain orders of magnitude can. It is only essential that the area of the outlet openings in use corresponds to the imaginary continuation of the outer surface of the application cylinder, so that no impulses can act on the paper web when the application cylinder is wrapped around it.
  • an application cylinder 1 in connection with guide rollers 4, 5 for the web 6 to be glued is shown very schematically, it being assumed that application cylinders 1 of different diameters are to be used in such an arrangement.

  • the basic principle of the invention is that a shaft 16 carrying the application cylinder 1, with its drive (not shown in the drawing), its storage and the other control means, should remain in the processing machine at all times and that the body 17 forming the periphery of the application cylinder 1 (FIG. 1) or 22 (Fig. 2) with the shaft 16 rotatably and firmly connected, but can be interchanged.

  • the adhesive feed channel 30 is connected at the end face of the individual insert 7 to an adhesive channel which is provided axially in the shaft 16. The connecting line of both channels is attached along the end face of the application cylinder.

In this case, the double arrangement of the angle lever 11 and sealing rollers 9 is unnecessary. Applications are also conceivable where more than two inserts 7 per application cylinder 1 are used. In this case, the arrangement of the angle levers 11 and sealing rollers 9 increases accordingly.
  • an application cylinder 1 with a different design is shown. Thereafter, the shaft 16 has a centering body 21 in a rotationally locking manner, which remains an integral part of the shaft 16 when application cylinders 1 of different sizes are to be connected to the shaft 16.

  • Two cylinder bodies 22 (cylinder half-shell) are now connected to the centering body 21, which consequently have the same prismatic guide adapted to the centering body 21. Consequently, such cylinder bodies 22 with the most varied diameters, but with the same centering surfaces, are kept in pairs in order to be able to adjust the cross gluing unit to the desired spacing of the cross gluing.

As FIG. 3 shows, two such radial screw connections 23 are provided on both end regions of the application cylinder 1. In the middle there is the assembly screw connection 29 shown in cross section in FIG. 4, which has the sense of firmly connecting the individual cylinder body 22 to the centering body 21, while the other cylinder body 22 is lifted off the centering body 21 after the screw connections 23 and 29 have been loosened .

  • there is an offset 27 for the insert which - if it is not too large - has no harmful effects on the guide of the web 6 on the application cylinder 1.
  • This offset 27 can be further reduced if, according to the exemplary embodiment in FIG. 5, the curved outer side of the insert 7 is provided with step-shaped steps 33, into which filler strips 35 are inserted. These filler strips 35 have a curved outer surface 37 which corresponds completely to the curvature of the application cylinder 1. Consequently, the offset 36 is significantly reduced compared to the offset 27 in FIG. 2.
  • FIG. 5 also shows the position of the outlet openings 8 in relation to the adhesive feed channel 30, which is essentially closed by a control shaft 32, the diameter of which is smaller than that of the adhesive feed channel 30.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Auftragen eines Klebstoffes in Form einer Queranleimung auf eine Bahn, insbesondere zur Verklebung von zwei sehr schnell laufenden Bahnen, in Rotationsdruckmaschinen, bei der ein wesentlicher Teilbereich des Mantels eines um seine Achse rotierend angetriebenen Auftragezylinders von der anzuleimenden Bahn umschlungen und der Umfang des Mantels entsprechend dem Abstand der Queranleimung oder einem ganzen Vielfachen hiervon bemessen ist, wobei der Klebstoff von einem ortsfesten axialen Klebstoffanschluß bis zu mindestens einem längs einer Mantellinie sich erstreckenden, mit dem Auftragezylinder umlaufenden und in einem Einsatz befindlichen Klebstoffzuführkanal geführt ist, von dem aus mindestens eine Reihe von in der Zylinderwandung befindlichen Austrittsöffnungen mit dem Klebstoff gesteuert versorgt werden.The invention relates to a device for applying an adhesive in the form of transverse gluing to a web, in particular for gluing two very fast-running webs, in rotary printing presses, in which a substantial portion of the jacket of an application cylinder rotating about its axis is separated from the web to be glued looped around and the circumference of the jacket is dimensioned according to the distance of the cross-gluing or a whole multiple thereof, the adhesive being guided from a stationary axial adhesive connection to at least one adhesive supply channel extending along a jacket line, rotating with the application cylinder and being in an insert, from which at least one row of outlet openings in the cylinder wall are supplied with the adhesive in a controlled manner.

Ein Querleimwerk mit diesen Merkmalen ist der DE-C-32 22 335 als bekannt zu entnehmen. Danach wird die Querbeleimung einer sehr schnell laufenden Papier- oder Stoffbahn mit Hilfe eines rotierenden Auftragezylinders veranlaßt, in dessen Umfang sich längs einer Mantellinie eine Vielzahl von Klebstoffaustrittsöffnungen befinden. Der Klebstoff wird punktweise durch diese Öffnungen ausgetragen. Aus der Summierung dieser Punkte ergibt sich die Linienverklebung.A cross glue unit with these features can be found in DE-C-32 22 335 as known. Then the cross-gluing of a very fast-running paper or fabric web is initiated with the help of a rotating application cylinder, in the circumference of which there are a large number of adhesive outlet openings along a surface line. The adhesive is discharged through these openings at points. The line bonding results from the summation of these points.

Wegen der hohen Bahngeschwindigkeit der zu verleimenden Bahnen besitzt der Auftragezylinder notwendigerweise eine große Rotationsgeschwindigkeit. Diese führt zu Problemen beim Austreten des Klebstoffes aus den Austrittsöffnungen. Um diese Fliehkraft abhängigen Bedingungen nicht zur Auswirkung kommen zu lassen, werden die Austrittsöffnungen von innen her verschlossen, und zwar dann, wenn die zu beleimende Bahn diese Austrittsöffnungen nicht überdeckt. Andererseits wird die Bahn in einem verhältnismäßig großen Umschlingungswinkel um den Auftragezylinder geführt. Während des Gleichlaufes der Bahn und des Auftragezylinders im Bereiche dieser Umschlingung werden die Austrittsöffnungen von innen her freigegeben, so daß der Klebstoff unter Fliehkrafteinwirkung gegen die Bahn geführt werden kann. Im Stillstand wird der Auftragezylinder in eine solche Stellung bewegt, daß von außen her Abdichtwalzen gegen die Austrittsöffnungen angedrückt werden können.Because of the high web speed of the webs to be glued, the application cylinder necessarily has a high rotational speed. This leads to problems when the adhesive emerges from the outlet openings. In order not to allow these centrifugal force-dependent conditions to have an effect, the outlet openings are closed from the inside, specifically when the web to be glued does not cover these outlet openings. On the other hand, the web is guided around the application cylinder in a relatively large wrap angle. During the synchronization of the web and the application cylinder in the area of this wrapping, the outlet openings are released from the inside, so that the adhesive can be guided against the web under the influence of centrifugal force. At standstill, the application cylinder is moved into such a position that sealing rollers can be pressed against the outlet openings from the outside.

Der Einsatz des Gegenstandes der DE-C-32 22 335 hat sich in der Druckindustrie außerordentlich bewährt. Besonders in der Tiefdrucktechnik entstehen jedoch Probleme, die mit den unterschiedlichen Längen der Druckvorlage zusammenhängen. Die Tiefdruckmaschinen sind in der Regel so gestaltet, daß die Tiefdruckzylinder gegen solche mit anderem Durchmesser ausgewechselt werden können, um so die Maschine an die geänderten Längen der Druckvorlagen anpassen zu können. Da der Auftragezylinder des Querleimwerkes einen ganz bestimmten Durchmesser aufweisen muß, damit die geforderten Abstände der Queranleimungen eingehalten werden können, würde sich die Notwendigkeit ergeben, bei Formatwechsei in der Tiefdruckmaschine nicht nur die Tiefdruckzylinder, sondern auch den oder die Auftragezylinder der Querleimwerke auszuwechseln. Das gleiche Problem tritt auch bei anderen Bearbeitungsmaschinen auf, bei denen der Abstand der Queranleimungen veränderbar sein soll.The use of the subject of DE-C-32 22 335 has proven itself extremely in the printing industry. However, especially in gravure printing, problems arise that are related to the different lengths of the artwork. The rotogravure machines are usually designed so that the rotogravure cylinders can be exchanged for those with a different diameter so that the machine can be adapted to the changed lengths of the printing templates. Since the application cylinder of the cross glue unit must have a very specific diameter so that the required spacing of the cross gluing can be maintained, there would be a need to change not only the gravure cylinder, but also the application cylinder or cylinders of the cross glue unit when changing the format in the gravure printing machine. The same problem also occurs with other processing machines in which the spacing of the cross-banding should be changeable.

Der Erfindung liegt somit die Aufgabe zugrunde, das vorbekannte Querleimwerk so weiterzugestalten, daß es ohne die Notwendigkeit des kompletten Austausches für die Erzeugung unterschiedlicher Abstände der Queranleimungen eingesetzt werden kann.The invention is therefore based on the object to further develop the known cross-gluing unit so that it can be used without the need for complete exchange for generating different distances between the cross-glues.

Unter Beibehaltung der vorbekannten Konstruktionsprinzipien wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß der Auftragezylinder in der Weise baugruppenmäßig unterteilt ist, daß eine mit ihrem Antrieb und ihrer Lagerung in der Bearbeitungsmaschine verbleibende Welle mit einem Zentrierkörper drehschlüssig versehen ist, an dem den Zylinderumfang bildende Körper wählbaren Durchmessers mit den darin befindlichen Einsätze austauschbar verschraubt sind.While maintaining the previously known design principles, this object is achieved according to the invention in that the application cylinder is sub-divided in such a way that a shaft remaining with its drive and its bearing in the processing machine is provided with a centering body on the body of selectable diameter forming the cylinder circumference are interchangeably screwed with the inserts therein.

Mit dieser erfindungsgemäßen Lösung ist die Möglichkeit gegeben, die Welle des Querleimwerkes mit ihrem Antrieb, ihrer Lagerung und sämtlichen Steuermitteln ständig in der Bearbeitungsmaschine zu belassen und bei Formatwechsel lediglich die den Umfang des Auftragezylinders bildenden Körper gegen solche passenden Durchmessers auszutauschen. Damit werden die Anlagekosten für die Querleimwerke der Bearbeitungsmaschinen wesentlich reduziert und im besonderen die Möglichkeiten geschaffen, im Tiefdruckverfahren hergestellte Druckerzeugnisse wechselnden Formates anstelle einer Klammerheftung zu verkleben.With this solution according to the invention it is possible to leave the shaft of the transverse gluing unit with its drive, its bearing and all control means in the processing machine at all times and, when changing the format, only to exchange the body forming the scope of the application cylinder for such a suitable diameter. This significantly reduces the system costs for the cross-gluing units of the processing machines and, in particular, creates the possibilities for gluing printing products of different formats produced by gravure printing instead of stapling.

Die Erfindung ist aber nicht auf den Einsatz in der Tiefdrucktechnik beschränkt.However, the invention is not restricted to use in gravure printing technology.

In den Unteransprüchen sind einige Varianten aufgezeigt, wie man die Welle und die den Umfang des Auftragezylinders bestimmenden Körper einfach gestalten, drehschlüssig miteinander verbinden und letztlich so befestigen kann, daß unter dem Einfluß der sehr hohen Bahngeschwindigkeit keine negativen Auswirkungen eintreten.In the subclaims, a few variants are shown of how the shaft and the body determining the circumference of the application cylinder can be designed in a simple manner, rotatably connected to one another and ultimately fastened in such a way that no negative effects occur under the influence of the very high path speed.

Die Erfindung bietet sogar die Möglichkeit, einen Einsatz für die Verwendung von im Durchmesser unterschiedlich großen Auftragezylindern vorzusehen, wobei die gekrümmte Außenseite des Einsatzes der Krümmung des kleinsten vorgesehenen Auftragezylinders entspricht. Wenn ein solcher Einsatz in einem Auftragezylinder verwendet wird, dessen Durchmesser größer als bei dem für den Einsatz ursprünglich gedachten Auftragezylinder ist, dann ergibt sich zufolge der unterschiedlichen Krümmungen von Einsatz und Auftragezylinder am Rande der Führung eine Stufe, die in gewissen Größenordnungen in Kauf genommen werden kann. Wesentlich ist lediglich, daß der Bereich der Austrittsöffnungen im Einsatz mit der gedachten Fortsetzung der Mantelfläche des Auftragezylinders übereinstimmt, so daß auf die Papierbahn beim Umschlingen des Auftragezylinders keine Impulse einwirken können.The invention even offers the possibility of providing an insert for the use of application cylinders of different diameters, the curved outside of the insert corresponding to the curvature of the smallest application cylinder provided. If such an insert is used in an application cylinder whose diameter is larger than that of the application cylinder originally intended for the application, then there is a step due to the different curvatures of the insert and application cylinder on the edge of the guide, which are accepted in certain orders of magnitude can. It is only essential that the area of the outlet openings in use corresponds to the imaginary continuation of the outer surface of the application cylinder, so that no impulses can act on the paper web when the application cylinder is wrapped around it.

Mit den Merkmalen des Unteranspruches 8 kann der Verwendungsspielraum für den einzelnen Einsatz noch vergrößert werden.With the features of subclaim 8, the range of use for individual use can be increased.

In den Ansprüchen 9 und 10 sind Lösungen aufgezeigt, wie bei sich ändernden Durchmessern des Auftragezylinders die Abdichtung der Austrittsöffnungen im Stillstand bewältigt werden kann. Einzelheiten der Erfindung ergeben sich aus der Zeichnung. In ihr ist die Erfindung schematisch und beispielsweise dargestellt. Es zeigen :

In the claims 9 and 10 solutions are shown how the sealing of the outlet openings can be managed at a standstill with changing diameters of the application cylinder. Details of the invention emerge from the drawing. In it, the invention is shown schematically and for example. Show it :
  • 1: a front view of an application cylinder with different diameters and an arrangement for sealing outlet openings.
  • 2 shows a cross section through an embodiment of a multi-part application cylinder,
  • 3: a top view of the application cylinder according to FIG. 2.

  • Fig. 5: a cross section through an insert with filler bars in an enlarged view and

Im Ausführungsbeispiel der Figur 1 ist ganz schematisch ein Auftragezylinder 1 im Zusammenhang mit Führungsrollen 4,5 für die zu beleimende Bahn 6 in Stirnansicht gezeigt, wobei davon ausgegangen wird, daß in eine solche Anordnung Auftragezylinder 1 unterschiedlichen Durchmessers eingesetzt werden sollen. Mit 2 ist ein solcher Auftragezylinder des größten Umfanges und mit 3 ein solcher des kleinsten Umfanges strichpunktiert gezeichnet.In the exemplary embodiment in FIG. 1, an application cylinder 1 in connection with guide rollers 4, 5 for the web 6 to be glued is shown very schematically, it being assumed that application cylinders 1 of different diameters are to be used in such an arrangement. Such an application cylinder of the largest circumference and 3 such of the smallest circumference is shown in dash-dot lines with 2.

Es sei grundsätzlich bemerkt, daß die konstruktive Gestaltung des Auftragezylinders 1 - soweit sie nachfolgend nicht gesondert beschrieben ist - der Offenbarung der DE-PS 32 22 335 entspricht, deren Inhalt zum Gegenstand der Offenbarung der Erfindung gemacht wird.It should be noted in principle that the structural design of the application cylinder 1 - insofar as it is not described separately below - corresponds to the disclosure of DE-PS 32 22 335, the content of which is made the subject of the disclosure of the invention.

Das Grundprinzip der Erfindung besteht darin, daß eine den Auftragezylinder 1 tragende Welle 16 mit ihrem in der Zeichnung nicht dargestellten Antrieb, ihrer Lagerung und den sonstigen Steuermitteln ständig in der Bearbeitungsmaschine verbleiben soll und daß den Umfang des Auftragezylinders 1 bildende Körper 17 (Figur 1) bzw. 22 (Fig. 2) mit der Welle 16 drehschlüssig und fest verbunden werden können, aber gegeneinander ausgetauscht werden können. Im Falle der Figur 1 ist diese Austauschmöglichkeit dadurch geschaffen, daß ein den Zylinderumfang im wesentlichen bestimmender Zylinderkörper 17 eine radiale Aussparung 18 aufweist, deren Breite dem Durchmesser der Welle 16 oder einem mit der Welle 16 verbundenen Zentrierkörper 21 entspricht. Dieser Zylinderkörper 17 wird mit Hilfe eines in die radiale Aussparung 18 passend einsetzbaren Klemmstückes 19 und der Verschraubung 20 fest mit der Welle 16 verbunden. Man braucht also lediglich das Klemmstück 19 zu lösen, um dann den Zylinderkörper 17 von der Welle 16 abheben zu können.The basic principle of the invention is that a shaft 16 carrying the application cylinder 1, with its drive (not shown in the drawing), its storage and the other control means, should remain in the processing machine at all times and that the body 17 forming the periphery of the application cylinder 1 (FIG. 1) or 22 (Fig. 2) with the shaft 16 rotatably and firmly connected, but can be interchanged. In the case of FIG. 1, this exchange possibility is created in that a cylinder body 17 which essentially determines the cylinder circumference has a radial recess 18, the width of which corresponds to the diameter of the shaft 16 or a centering body 21 connected to the shaft 16. This cylinder body 17 is firmly connected to the shaft 16 with the aid of a clamping piece 19 which can be inserted into the radial recess 18 and the screw connection 20. It is therefore only necessary to loosen the clamping piece 19 in order to then be able to lift the cylinder body 17 off the shaft 16.

Im Zylinderkörper 17 befinden sich beim Ausführungsbeispiel zwei Führungen 26 zur Aufnahme von Einsätzen 7, welche, wie Figur 5 bzw. die DE-PS 32 22 335 deutlicher zeigen, einen Klebstoffzuführkanal 30, sowie mindestens eine Reihe von Austrittsöffnungen 8 enthalten, die sich längs einer Mantellinie des Auftragezylinders 1 erstrecken. Diese Austrittsöffnungen 8 sind mit dem Klebstoffzuführkanal 30 in Verbindung, können aber von innen her durch ein besonderes Verschlußelement 31 versperrt werden. Der Klebstoffzuführkanal 30 wird an der Stirnseite des einzelnen Einsatzes 7 mit einem Klebstoffkanal verbunden, der in der Welle 16 axial vorgesehen ist. Die Verbindungsleitung beider Kanäle wird längs der Stirnfläche des Auftragezylinders angebracht.In the embodiment, there are two guides 26 in the cylinder body 17 for receiving inserts 7, which, as shown in FIG. 5 and DE-PS 32 22 335 more clearly, contain an adhesive feed channel 30 and at least one row of outlet openings 8, which are located along one Extend the generatrix of the application cylinder 1. These outlet openings 8 are connected to the adhesive feed channel 30, but can be blocked from the inside by a special closure element 31. The adhesive feed channel 30 is connected at the end face of the individual insert 7 to an adhesive channel which is provided axially in the shaft 16. The connecting line of both channels is attached along the end face of the application cylinder.

Die Bahn 6 wird mit Hilfe der Führungsrollen 4,5 so geführt, daß sich eine möglichst große Umschlingung des Auftragezylinders 1 ergibt. Da aber Auftragezylinder unterschiedlichen Durchmessers eingesetzt werden sollen, ergibt sich die Notwendigkeit, die Führungsrollen 4, 5 verstellbar anzuordnen. Mit 4' und 5' ist die Lage dieser Führungsrollen bei einem Auftragezylinder 1 mit dem größten Umfang 2 strichpunktiert angedeutet.The web 6 is guided with the aid of the guide rollers 4, 5 so that the largest possible wrap around the application cylinder 1 results. However, since application cylinders of different diameters are to be used, there is the need to arrange the guide rollers 4, 5 in an adjustable manner. With 4 'and 5' the position of these guide rollers in an application cylinder 1 with the largest circumference 2 is indicated by dash-dotted lines.

Die Queranleimung der Bahn 6 erfolgt wie beim DE-Patent 32 22 335 in der Weise, daß die Austrittsöffnungen 8 von innen her geöffnet werden, sobald die Bahn 6 im Bereiche der Umschlingung des Auftragezylinders die Austrittsöffnungen 8 abgedeckt hat. Während des Gleichlaufes von Bahn 6 und Zylinder 1 innerhalb dieses Abdeckbereiches bleiben die Austrittsöffnungen 8 geöffnet. Sie werden verschlossen, bevor die Bahn 6 sich vom Umfang des Auftragezylinders 1 abzuheben beginnt. Aus der Vielzahl der nebeneinander angeordneten, im Durchmesser kleinen Austrittsöffnungen 8 ergibt sich eine linienartige Querverleimung auf der Papierbahn 6, die kurz danach mit einer anderen Bahn zusammengeführt wird.The cross-gluing of the web 6 is carried out, as in DE patent 32 22 335, in such a way that the outlet openings 8 are opened from the inside as soon as the web 6 has covered the outlet openings 8 in the area of the wrap around the application cylinder. The outlet openings 8 remain open during the synchronization of the path 6 and cylinder 1 within this covering area. They are closed before the web 6 begins to lift off the circumference of the application cylinder 1. A line-like transverse gluing on the paper web 6 results from the large number of outlet openings 8 arranged next to one another with a small diameter, which is brought together shortly thereafter with another web.

Bei Stillstand des Auftragezylinders 1, insbesondere bei Arbeitspausen, werden Abdichtwalzen 9 von außen her gegen die Austrittsöffnungen 8 angestellt, um das Eintrocknen des Klebstoffes und das Verschließen der Austrittsöffnungen 8 zu verhindern. Die einzelne Abdichtwalze 9 ist an einem Winkelhebel 11 gelagert, der um die Schwenkachse 13 schwenkbar ist. Die Lagerung der Abdichtwalze 9 ist an einem aufrechten Schenkel 12 des Winkelhebels 11 vorgesehen, der so konstruiert ist, daß die Führungsrollen 4, 5 in ihrer weitesten Stellung 4', 5' nicht die Bewegung des Winkelhebels 11 behindern. Die Lage der Schwenkachse 13 ist dabei so gewählt, daß sie in der Mitte zwischen den beiden Endstellungen der Abdichtwalze 9, bezogen auf den kleinsten und den größten Umfang 3, 2 des Auftragezylinders 1 zu liegen kommt. Wie aus der Zeichnung der Figur 1 ersichtlich ist, wird die Achse der Abdichtwalze 9 beim Verschwenken um die Schwenkachse 13 in einem Kreisbogen geführt, der Relativverschiebung der Austrittsöffnung 8 zur nächstgelegenen Oberfläche der Abdichtwalze 9 zur Folge hat. Um dennoch eine genaue Abdeckung der Austrittsöffnungen 8 zu erreichen, ist im Winkelhebel 11 ein Langloch 10 vorgesehen, entlang welchem die Abdichtwalze 9 verstellbar geführt ist.When the application cylinder 1 is at a standstill, in particular during work breaks, sealing rollers 9 are set against the outlet openings 8 from the outside in order to prevent the adhesive from drying out and the outlet openings 8 from being closed. The individual sealing roller 9 is mounted on an angle lever 11 which is pivotable about the pivot axis 13. The storage of the sealing roller 9 is provided on an upright leg 12 of the angle lever 11, which is constructed so that the guide rollers 4, 5 in their widest position 4 ', 5' do not hinder the movement of the angle lever 11. The position of the pivot axis 13 is chosen so that it comes to lie in the middle between the two end positions of the sealing roller 9, based on the smallest and the largest circumference 3, 2 of the application cylinder 1. As can be seen from the drawing of Figure 1, the axis of the sealing roller 9 when pivoting about Swivel axis 13 guided in a circular arc, the relative displacement of the outlet opening 8 to the closest surface of the sealing roller 9 results. In order nevertheless to achieve a precise covering of the outlet openings 8, an elongated hole 10 is provided in the angle lever 11, along which the sealing roller 9 is guided in an adjustable manner.

Wenn, wie im Falle der Figur 1, zwei Einsätze 7 je Auftragezylinder 1 zur Verwendung kommen, sind demgemäß auch zwei Winkelhebel 11 mit Abdichtwalzen 9 vorgesehen, die zweckmäßigerweise über eine gemeinsame Hubeinrichtung 14 und über die Laschen 15 verstellt werden können.If, as in the case of FIG. 1, two inserts 7 per application cylinder 1 are used, two angle levers 11 with sealing rollers 9 are accordingly also provided, which can expediently be adjusted via a common lifting device 14 and via the tabs 15.

Es sei aber darauf hingewiesen, daß die Erfindung auch solche Queranleimwerke umfaßt, bei denen nur ein Einsatz 7 je Auftragezylinder 1 zur Verwendung kommt. In diesem Fall erübrigt sich die doppelte Anordnung der Winkelhebel 11 und Abdichtwalzen 9. Denkbar sind auch Anwendungen, wo mehr als zwei Einsätze 7 je Auftragezylinder 1 zur Verwendung kommen. In diesem Fall erhöht sich die Anordnung der Winkelhebel 11 und Abdichtwalzen 9 entsprechend.However, it should be pointed out that the invention also encompasses such transverse gluing units in which only one insert 7 per application cylinder 1 is used. In this case, the double arrangement of the angle lever 11 and sealing rollers 9 is unnecessary. Applications are also conceivable where more than two inserts 7 per application cylinder 1 are used. In this case, the arrangement of the angle levers 11 and sealing rollers 9 increases accordingly.

Im Ausführungsbeispiel der Figur 2 ist ein im Aufbau anders gestalteter Auftragezylinder 1 gezeigt. Danach weist die Welle 16 drehschlüssig einen Zentrierkörper 21 auf, der fester Bestandteil der Welle 16 bleibt, wenn Auftragezylinder 1 unterschiedlicher Größe mit der Welle 16 verbunden werden sollen. Der Zentrierkörper 21 kann mit der Welle verschraubt, verschweißt, aufgeschrumpft, oder in sonstiger Weise fest verbunden sein.In the exemplary embodiment in FIG. 2, an application cylinder 1 with a different design is shown. Thereafter, the shaft 16 has a centering body 21 in a rotationally locking manner, which remains an integral part of the shaft 16 when application cylinders 1 of different sizes are to be connected to the shaft 16. The centering body 21 can be screwed to the shaft, welded, shrunk on, or firmly connected in some other way.

Mit dem Zentrierkörper 21 werden nun zwei Zylinderkörper 22 (Zylinderhalbschale) verbunden, die folglich die gleiche prismatische, dem Zentrierkörper 21 angepaßte Führung aufweisen. Es werden folglich paarweise solche Zylinderkörper 22 mit den verschiedensten Durchmesser-Abstufungen, aber den gleichen Zentrierflächen bereitgehalten, um das Querleimwerk auf die gewünschten Abstände der Querverleimungen einstellen zu können.Two cylinder bodies 22 (cylinder half-shell) are now connected to the centering body 21, which consequently have the same prismatic guide adapted to the centering body 21. Consequently, such cylinder bodies 22 with the most varied diameters, but with the same centering surfaces, are kept in pairs in order to be able to adjust the cross gluing unit to the desired spacing of the cross gluing.

Wegen der hohen Rotationsgeschwindigkeiten ist beim Ausführungsbeispiel der Figuren 2-4 eine spezielle Verschraubung gewählt, die außerdem die Montage und Demontage der Auftragezylinder 1 erleichtern sollen. Die Radialverschraubung 23 gemäß Figur 2 verspannt zunächst die beiden Zylinderkörper 22 gegeneinander und läßt diese zur festen Anlage mit den längeren Seiten des im Querschnitt rechteckigen Zentrierkörpers 21 kommen. Wie die Figur 3 zeigt, sind zwei solcher Radialverschraubungen 23 an beiden Endbereichen des Auftragezylinders 1 vorgesehen. In der Mitte befindet sich die in Figur 4 im Querschnitt gezeigte Montageverschraubung 29, welche den Sinn hat, den einzelnen Zylinderkörper 22 noch fest mit dem Zentrierkörper 21 zu verbinden, während der andere Zylinderkörper 22 nach Lösen der Verschraubungen 23 und 29 vom Zentrierkörper 21 abgehoben wird.Because of the high rotational speeds, a special screw connection is selected in the embodiment of FIGS. 2-4, which should also facilitate the assembly and disassembly of the application cylinder 1. The radial screw connection 23 according to FIG. 2 first braces the two cylinder bodies 22 against one another and allows them to come into firm contact with the longer sides of the centering body 21, which is rectangular in cross section. As FIG. 3 shows, two such radial screw connections 23 are provided on both end regions of the application cylinder 1. In the middle there is the assembly screw connection 29 shown in cross section in FIG. 4, which has the sense of firmly connecting the individual cylinder body 22 to the centering body 21, while the other cylinder body 22 is lifted off the centering body 21 after the screw connections 23 and 29 have been loosened .

Damit eine praktisch unlösbare und unter der hohen Fliehkraft unbeeinflußbare Verbindung zwischen den Zylinderkörpern 22 und dem Zentrierkörper 21 zustandekommt, sind die Zylinderkörper 22 durch die periphere Verschraubung 24 unmittelbar und durch die Querverschraubung 25 noch zusätzlich mit dem Zentrierkörper 21 verschraubt.So that a practically inseparable and uninfluenced connection between the cylinder bodies 22 and the centering body 21 is achieved, the cylinder bodies 22 are screwed directly to the centering body 21 by the peripheral screw connection 24 and additionally by the cross screw connection 25.

Im Beispiel der Figur 2 ist ferner gezeigt, daß die gekrümmte Außenseite 34 des Einsatzes 7 durchaus eine größere Krümmung als die Mantelfläche des Auftragezylinders 1 aufweisen kann, sofern sichergestellt ist, daß der die Austrittsöffnungen 8 umgebende Bereich die gedachte Verlängerung der Mantellinie des Auftragezylinders 1 tangiert. Auf diese Weise ist es nämlich möglich, ein- und denselben Einsatz 7 für im Durchmesser unterschiedlich große Auftragezylinder 1 zu verwenden. Es ergibt sich am Übergang des Einsatzes 7 zur Führung 26 für den Einsatz ein Versatz 27, der - falls er nicht zu groß ist - keine schädlichen Einwirkungen auf die Führung der Bahn 6 am Auftragezylinder 1 besitzt.In the example in FIG. 2, it is also shown that the curved outer side 34 of the insert 7 can have a greater curvature than the outer surface of the application cylinder 1, provided that it is ensured that the area surrounding the outlet openings 8 affects the imaginary extension of the surface line of the application cylinder 1 . In this way it is in fact possible to use one and the same insert 7 for application cylinders 1 of different sizes. At the transition from the insert 7 to the guide 26, there is an offset 27 for the insert which - if it is not too large - has no harmful effects on the guide of the web 6 on the application cylinder 1.

Dieser Versatz 27 läßt sich noch reduzieren, wenn man gemäß Ausführungsbeispiel der Figur 5 die gekrümmte Außenseite des Einsatzes 7 mit stufenförmigen Absetzungen 33 versieht, in welche Fülleisten 35 eingesetzt werden. Diese Fülleisten 35 haben eine gewölbte Außenfläche 37, die völlig mit der Krümmung des Auftragezylinders 1 übereinstimmt. Folglich ist der Versatz 36 gegenüber dem Versatz 27 in Figur 2 wesentlich reduziert.This offset 27 can be further reduced if, according to the exemplary embodiment in FIG. 5, the curved outer side of the insert 7 is provided with step-shaped steps 33, into which filler strips 35 are inserted. These filler strips 35 have a curved outer surface 37 which corresponds completely to the curvature of the application cylinder 1. Consequently, the offset 36 is significantly reduced compared to the offset 27 in FIG. 2.

Figur 5 zeigt im übrigen die Lage der Austrittsöffnungen 8 im Verhältnis zum Klebstoffzuführkanal 30, der im wesentlichen durch eine Steuerwelle 32 verschlossen ist, deren Durchmesser geringer als derjenige des Klebstoffzuführkanals 30 ist. In dem verbleibenden Spalt wird ein an der Steuerwelle 32 befestigtes Verschlußelement 31 bewegt, das die Austrittsöffnungen 8 innenseitig abdeckt und damit den Klebstoff, der sich im Spalt zwischen der Kanalwandung und der Steuerwelle 32 befindet, daran hindert, durch die Austrittsöffnung 8 zu treten.FIG. 5 also shows the position of the outlet openings 8 in relation to the adhesive feed channel 30, which is essentially closed by a control shaft 32, the diameter of which is smaller than that of the adhesive feed channel 30. In the remaining gap, a closure element 31 fastened to the control shaft 32 is moved, which covers the outlet openings 8 on the inside and thus prevents the adhesive, which is located in the gap between the channel wall and the control shaft 32, from passing through the outlet opening 8.

Eine noch einfachere Möglichkeit der Anpassung des Querleimwerkes an unterschiedliche Durchmesser des Auftragezylinders 1 ist aus Figur 6 ersichtlich. Der Einsatz 7 weist ebenfalls stufenförmige Absetzungen 33 auf, in die anstelle der Füllleisten 35 der Figur 5 ein den Einsatz 7 abdeckendes Überbrückungsglied 40 eingepaßt wird. Dieses Überbrückungsglied 40 weist an seiner Außenseite 42 die gleiche Krümmung wie der Auftragezylinder 1 auf. Ändert sich der Durchmesser des Auftragezylinders 1, dann braucht nur das Überbrückungsglied 40 angepaßt zu werden, wohingegen der Einsatz 7 unverändert bleibt. Der Einsatz 7 weist eine zurückversetzte Anschlagfläche 39 auf, welche die Austrittsöffnungen 8 enthält und gegen die das Überbrücküngsglied 40 gespannt wird. In ihm befinden sich Fortsetzungen 41 der Austrittsöffnungen 8.An even simpler possibility of adapting the cross gluing unit to different diameters of the application cylinder 1 can be seen in FIG. 6. The insert 7 also has step-shaped shoulders 33, into which a bridging member 40 covering the insert 7 is fitted instead of the filler strips 35 in FIG. This bridging member 40 has the same curvature as the application cylinder 1 on its outer side 42. If the diameter of the application cylinder 1 changes, then only the bridging member 40 needs to be adapted, whereas the insert 7 remains unchanged. The insert 7 has a set back stop surface 39 which contains the outlet openings 8 and against which the bridging member 40 is tensioned. There are continuations 41 of the outlet openings 8.

Das Verschlußelement 31 befindet sich entsprechend der Wanddicke des Einsatzes 7 und des Überbrückungsgliedes 40 in einer zurückversetzten Lage, was sich aber nicht nachteilig auf das Auftrageverhalten des Querleimwerkes auswirkt.The closure element 31 is in a recessed position according to the wall thickness of the insert 7 and the bridging member 40, but this is not disadvantageous to the Application behavior of the cross glue unit affects.

Man kann nun die Fortsetzung 41 der Austrittsöffnung 8 innenseitig erweitern und damit Raum für Stöpsel 43 schaffen. Mit deren Hilfe läßt sich das Auftragebild für den Klebstoffauftrag, insbesondere dessen Breite, nach Wunsch verändern, denn wo ein Stöpsel ist, kann kein Klebstoff aufgetragen werden.You can now expand the continuation 41 of the outlet opening 8 on the inside and thus create space for plugs 43. With their help, the application image for the adhesive application, in particular its width, can be changed as desired, because where there is a stopper, no adhesive can be applied.

Dieser Gedanke läßt sich auch bei anderen Gestaltungen des Querleimwerkes verwirklichen.This idea can also be realized in other designs of the cross gluing unit.
