Description

Die Erfindung betrifft eine Lackieranlage gem. des Oberbegriffs des Anspruchs 1 mit einer Vorrichtung für ein Vernetzen eines Schutzlackes oder dergleichen auf einer wickelbaren Materialbahn, die ein thermisch isolierendes Gehäuse mit einem temperierten Innenraum aufweist, in dem die Materialbahn für ein Vernetzen des Schutzlacks mehrfach umgelenkt wird, wie sie bspw. aus der WO 2006/013 911 A1 oder der US 2005/021 4 453 A1 bekannt ist.The invention relates to a painting plant acc. of the preamble of claim 1 with a device for crosslinking a protective lacquer or the like on a windable material web having a thermally insulating housing with a tempered interior, in which the web is repeatedly deflected for crosslinking the protective lacquer, as for example. From the WO 2006/013 911 A1 or the US 2005/021 4 453 A1 is known.

Bei einer anderen bekannten, kombinierten Druck- und Lackieranlage wird eine Materialbahn, bspw. Papierbahnen, Kunststofffolien oder dergleichen, von einer Rolle abgewickelt und in der Regel durch mehrere Druckwerke geführt. Ist die Materialbahn bedruckt, erfolgt der Auftrag eines Schutzlackes. Solche Schutzlacke sind vielfältig bekannt. Die meisten dieser Lacke benötigen für ein Aushärten vorgegebene Temperaturen und es bedarf einer gewissen Zeit, bis eine Vernetzung einzelner Makromoleküle erfolgt ist bzw. eine Vernetzung herbeiführende Reaktionen an bereits bestehenden Polymeren erfolgt sind.In another known, combined printing and varnishing a web, for example. Paper webs, plastic films or the like, unwound from a roll and usually passed through several printing units. If the material web is printed, the application of a protective varnish takes place. Such protective coatings are widely known. Most of these paints require predetermined temperatures for curing and it takes a certain time until a crosslinking of individual macromolecules has taken place or a crosslinking reactions have taken place on already existing polymers.

Bei dieser Druck- und Lackieranlage wird die bedruckte und hernach mit einem Schutzlack versehene Materialbahn auf einem Luftbett in einer Ebene durch einen Trockner geführt. Dies hat zwar den Vorteil, dass der Transport der Materialbahn berührungslos erfolgt, hat aber den Nachteil, dass ein solcher Trockner von erheblicher Länge sein muss, um dem Schutzlack ausreichend Zeit für ein Trocknen und Vernetzen zu geben.In this printing and varnishing system, the printed and subsequently provided with a protective coating material web on a Airbed guided in a plane through a dryer. Although this has the advantage that the transport of the web takes place without contact, but has the disadvantage that such a dryer must be of considerable length in order to give the protective lacquer sufficient time for drying and crosslinking.

Vor diesem Hintergrund macht die Erfindung es sich zur Aufgabe, eine kompakte Lackieranlage für eine Materialbahn zur Verfügung zu stellen, bei der weiter eine Vorrichtung für ein Vernetzen des Schutzlackes oder dergleichen vorgesehen ist, so dass die räumliche Gestaltung der Lackieranlage weitgehend freibleibend ist.Against this background, the object of the invention is to provide a compact painting installation for a material web, in which a device for crosslinking the protective coating or the like is further provided, so that the spatial design of the painting installation is largely non-binding.

Gelöst wird diese technische Problematik durch das Zurverfügungstellen einer Lackieranlage, bei der gem. des Anspruchs 1 darauf abgestellt ist, dass das Gehäuse der Vorrichtung innerhalb des Trockners angeordnet ist.This technical problem is solved by the provision of a paint shop, gem. of claim 1 is geared to that the housing of the device is disposed within the dryer.

Der Vorteil einer derartigen Vorrichtung ist eine kompakte Bauweise, die weiter durch die Maßnahme verbessert werden kann, dass die Zahl der Umlenkungen der Materialbahn mehr als zwei beträgt, wobei es von Vorteil sein kann, wenn die Zahl der Umlenkungen ungerade ist. Es erfolgt dann die Zufuhr der Materialbahn an bzw. der Austritt aus der Vorrichtung auf derselben Seite der Vorrichtung. Ist die Anzahl eine gerade, so wird die Vorrichtung nach der Erfindung durchlaufen.The advantage of such a device is a compact design, which can be further improved by the measure that the number of deflections of the material web is more than two, and it may be advantageous if the number of deflections is odd. It then takes place the supply of the material web or the exit from the device on the same side of the device. If the number is even, the device according to the invention is run through.

Da die Schutzlacke durchaus unterschiedliche Vernetzungstemperaturen benötigen, ist weiter vorgesehen, dass die Temperatur des Innenraums der Vorrichtung einstellbar zwischen 80° und 250° betragen kann. Optimale Vernetzungstemperaturen können dadurch bereit gestellt werden.Since the protective lacquers definitely need different crosslinking temperatures, it is further provided that the temperature of the interior of the device can be adjustable between 80 ° and 250 °. Optimum crosslinking temperatures can be provided thereby.

In weiterer Ausgestaltung kann vorgesehen sein, dass innerhalb der Vorrichtung verschiedene Temperaturzonen einstellbar sind. Dabei ist insbesondere daran gedacht, dass sich eine derartige Temperaturzone über einen Abschnitt der Materialbahn zwischen zwei Umlenkrollen erstreckt. Alternativ kann die Temperatur über den Weg der Materialbahn zwischen zwei Umlenkrollen ansteigen oder absinken.In a further embodiment it can be provided that different temperature zones can be set within the device. It is particularly thought that extends such a temperature zone over a portion of the web between two pulleys. Alternatively, the temperature can increase or decrease over the path of the material web between two deflection rollers.

Unabhängig davon kann so die Temperatur nach dem Eintritt der Materialbahn in die Vorrichtung materialschonend auf die Vernetzungstemperatur ansteigen und wird vor einem Austritt die Materialbahn wieder abgekühlt.Independently of this, the temperature after the material web has entered the device can thus gently rise to the crosslinking temperature and, before it leaves, the material web is cooled again.

Weiter kann vorgesehen sein, dass die Länge der Materialbahn in der Vorrichtung zwischen 10 m und 20 m beträgt.It can further be provided that the length of the material web in the device is between 10 m and 20 m.

Aufgrund dieser Maßnahme ist die Verweildauer der Materialbahn in der Vorrichtung ausreichend bemessen, um eine zumindest für den weiteren Prozessablauf ausreichende Vernetzung zu erhalten.Due to this measure, the residence time of the material web in the device is dimensioned sufficiently to obtain a sufficient at least for the further process flow networking.

Ist keine Vernetzung erforderlich, kann aufgrund der Maßnahme, dass bspw. gegenüberliegend einer Eintrittsöffnung eine Austrittsöffnung in dem Gehäuse angeordnet ist, materialschonend und schnell in einem Freiraum eine Durchführung der Materialbahn durch die Vorrichtung ohne Umlenkung erfolgen.If no cross-linking is required, due to the measure that, for example, opposite to an inlet opening, an outlet opening is arranged in the housing, the material web can be carried through the device without diversion in a material-friendly and rapid manner in a free space.

Ist weiter vorgesehen, dass eine Achse einer Umlenkrolle verfahrbar ist, kann nicht nur die Spannung der Materialbahn beeinflusst werden, sondern kann darüber hinaus an die Funktion eines Bandspeichers gedacht sein.If it is further provided that an axis of a deflection roller can be moved, not only can the tension of the material web be influenced, but in addition it can be thought of the function of a belt store.

Alternativ kann daran gedacht sein, dass über der Lackauftragsvorrichtung der Trockner, beispielsweise ein Prallstrahltrockner, angeordnet ist, der eine vergleichsweise geringe Grundfläche nur benötigt.Alternatively, it may be thought that over the paint application device of the dryer, for example a Impinged jet dryer, is arranged, which only requires a comparatively small footprint.

Unabhängig von der Bauform des Trockners können dieser und das Gehäuse der Vorrichtung nach der Erfindung platzsparend wenigstens eine gemeinsame Wand aufweisen, die Mittel für das Führen und/oder Trocknen der Materialbahn aufweist.Regardless of the design of the dryer this and the housing of the device according to the invention can save space to have at least one common wall having means for guiding and / or drying the material web.

Je nach Bauform des Trockners kann darüber hinaus, äußerst platzsparend, das Gehäuse der Vorrichtung innerhalb des Trockners angeordnet sein.Depending on the design of the dryer can be arranged within the dryer, moreover, extremely space-saving, the housing of the device.

Die Anordnung des Gehäuses der Vorrichtung innerhalb des Trockners ist auch thermisch von Vorteil, wenn die Temperaturdifferenz zwischen der Temperatur im Trockner von bspw. 150°C und der im Inneren der Vorrichtung von bspw. 200°C gering ist. Die thermische Isolation der Vorrichtung kann dann geringer gehalten sein als bspw. gegenüber einer Zimmertemperatur.The arrangement of the housing of the device within the dryer is also thermally advantageous if the temperature difference between the temperature in the dryer of, for example, 150 ° C and that in the interior of the device of, for example. 200 ° C is low. The thermal insulation of the device can then be kept lower than, for example, compared to a room temperature.

Weiter kann dann vorgesehen sein, dass die Materialbahn in dem Trockner um drei Seiten des Gehäuses geführt ist und dass das Äußere des Gehäuses Mittel für das Führen und/oder Trocknen der Materialbahn aufweist. Dabei ist im Wesentlichen an Führungsrollen, Trocknerdüsen und Leitungen gedacht.Furthermore, it can then be provided that the material web in the dryer is guided around three sides of the housing and that the exterior of the housing has means for guiding and / or drying the material web. It is mainly intended for guide rollers, dryer nozzles and pipes.

In weiterer konstruktiver Ausgestaltung ist vorgesehen, dass vor der Zufuhr der Materialbahn an die Vorrichtung eine Dreifachumlenkung der Materialbahn erfolgt. Diese Maßnahme hat den Vorteil, dass eine lackierte und getrocknete Materialbahn an der Vorrichtung nach der Erfindung vorbeigeführt werden kann, wenn der aufgebrachte Schutzlack nach dem Trocknen keiner weiteren Vernetzung bedarf.In a further structural embodiment, it is provided that a triple deflection of the material web takes place before the material web is fed to the device. This measure has the advantage that a lacquered and dried material web can be guided past the device according to the invention if the applied protective lacquer requires no further crosslinking after drying.

Ist insbesondere daran gedacht, dass die Vorrichtung in Zuführrichtung der Materialbahn in dem Trockner der Lackieranlage angeordnet ist, erfolgt die Abführung der Materialbahn von der Vorrichtung über die Oberseite des Trockners.If, in particular, it is intended that the device is arranged in the feed direction of the material web in the dryer of the paint shop, the removal of the material web from the device takes place via the top side of the dryer.

Figur 1 zeigt beispielhaft einen Längsschnitt durch eine kombinierte Druck- und Lackieranlage 1. Das Bedrucken und Lackieren einer Materialbahn 2 erfolgt in Figur 1 im Wesentlichen von rechts nach links. FIG. 1 shows an example of a longitudinal section through a combined printing and painting 1. The printing and painting a web 2 takes place in FIG. 1 essentially from right to left.

Die Materialbahn 2 wird von einer Rolle 3 abgezogen und durchläuft hier vier Druckwerke 4-7, denen jeweils ein Prallstrahltrockner 8-11 nachgeschaltet ist.The material web 2 is withdrawn from a roll 3 and passes through four printing units 4-7, which in each case an impingement jet dryer 8-11 is connected downstream.

Von dem letzten Prallstrahltrockner 11 wird die Materialbahn 2 einer Lackauftragsvorrichtung 12 einer Lackieranlage 14 zugeführt, vgl. Figur 2.From the last impact jet dryer 11, the material web 2 is fed to a paint application device 12 of a painting installation 14, cf. FIG. 2 ,

Nach dem Aufbringen des Schutzlackes auf die bedruckte Materialbahn 2 erfolgt eine Trocknung in einem Prallstrahltrockner 13, der deutlich größer bemessen ist als die Prallstrahltrockner 8-11 der Druckwerke 4-7. Übliche Trockentemperaturen in dem Prallstrahltrockner 13 der Lackieranlage 14 belaufen sich bei üblichen Lacken auf 80°C bist 180°C.After the protective lacquer has been applied to the printed material web 2, it is dried in an impingement jet dryer 13, which is dimensioned considerably larger than the impact blast dryers 8-11 of the printing units 4-7. Conventional drying temperatures in the impingement jet dryer 13 of the painting installation 14 amount to 80 ° C. for conventional paints at 180 ° C.

Abgesetzt von dem Prallstrahltrockner 13 ist für ein Vernetzen entsprechender Schutzlacke eine Vorrichtung 15 vorgesehen.Deposed from the impingement jet dryer 13, a device 15 is provided for crosslinking corresponding protective lacquers.

Vor der Vorrichtung 15 sind drei Umlenkrollen 16-18 angeordnet, die einer strickpunktiert dargestellten Materialbahn 19 das Passieren der Vorrichtung 15 ermöglichen, wenn ein aufgebrachter Schutzlack keiner Vernetzung bedarf.In front of the device 15, three deflection rollers 16-18 are arranged, which allow a material web 19 shown in dot-dashed lines to pass through the device 15 when an applied protective lacquer requires no crosslinking.

Unabhängig davon wird die Materialbahn 19 oder die aus der Vorrichtung 15 austretende Materialbahn 20 über den Prallstrahltrockner 13 weiteren Bearbeitungsstationen wie Schneidstationen oder dergleichen zugeführt, um endlich am Prozessende zu einer oder mehreren Rollen 21 aufgerollt zu werden.Independently of this, the material web 19 or the material web 20 emerging from the device 15 is fed via the impact jet dryer 13 to further processing stations such as cutting stations or the like in order to finally be rolled up to one or more rollers 21 at the end of the process.

Die Figuren 1 und 2 lassen erkennen, dass die Vorrichtung 15 oberhalb, hier unmittelbar über dem Prallstrahltrockner 11 des Druckwerks 7 angeordnet ist, in den Figuren 1 und 2 rechts neben dem Prallstrahltrockner 13 der Lackieranlage 14. Unschwer ist weiter erkennbar, dass eine Anordnung links oder oberhalb des Prallstrahltrockners 13 alternativ möglich ist. Hier wird jedoch der Freiraum über dem Prallstrahltrockner 11 genutzt, wobei die Oberseite der Vorrichtung 15 unterhalb der Oberseite des Prallstrahltrockners 13 angeordnet ist.The FIGS. 1 and 2 let recognize that the device 15 above, here just above the impingement jet dryer 11th of the printing unit 7 is arranged in the FIGS. 1 and 2 It is not difficult to see further that an arrangement to the left or above the impingement jet dryer 13 is alternatively possible. Here, however, the space above the impact jet dryer 11 is used, with the top of the device 15 is disposed below the top of the impingement jet dryer 13.

Die Vorrichtung 15 für das Vernetzen des Schutzlackes weist ein Gehäuse 22 auf, das, entsprechend thermisch isoliert, einen temperierten Innenraum 23 umschließt. Die Temperatur des Innenraums 23 beträgt einstellbar zwischen 80° und 250°, um optimale Vernetzungstemperaturen für die verwendeten Schutzlacke sicherzustellen.The device 15 for crosslinking the protective coating has a housing 22, which, correspondingly thermally insulated, encloses a temperature-controlled internal space 23. The temperature of the interior 23 is adjustable between 80 ° and 250 °, in order to ensure optimum crosslinking temperatures for the protective coatings used.

Wie insbesondere die Figur 2 aufzeigt, wird die Materialbahn 20 in dem Innenraum 23 beispielhaft dreimal umgelenkt. Aufgrund dieser Maßnahme kann erreicht werden, dass die Verweildauer der Materialbahn 20 in der Vorrichtung 15 ausreichend bemessen ist, um eine optimale Vernetzung sicherzustellen. Dabei beträgt die Länge der Materialbahn 20 in der Vorrichtung 15 zwischen 10 m und 20 m.How the particular FIG. 2 shows, the web 20 is deflected in the interior 23 by way of example three times. Due to this measure, it can be achieved that the dwell time of the material web 20 in the device 15 is dimensioned sufficiently to ensure optimum crosslinking. The length of the material web 20 in the device 15 is between 10 m and 20 m.

Dennoch ist es durch die konstruktive Ausbildung der Vorrichtung 15 ermöglicht, eine äußerst kompakte, Bauweise der Lackieranlage 14 zu erreichen. So beträgt beispielhaft die Länge der Vorrichtung 15 in Verarbeitungsrichtung der Materialbahn 2 bei einer Aufnahmekapazität von ca. 15 m der Materialbahn 20 lediglich 3-4 m und passt sich damit die Länge der Vorrichtung 15 dem üblichen Industrieraster einer Halle oder dergleichen an.Nevertheless, it is possible by the structural design of the device 15 to achieve an extremely compact, construction of the paint shop 14. For example, the length of the device 15 in the processing direction of the material web 2 at a receiving capacity of about 15 m of the web 20 only 3-4 m and thus adapts to the length of the device 15 to the usual industrial grid of a hall or the like.

Figur 3 zeigt wiederum einen Prallstrahltrockner 25, angeordnet über einer Lacksauftragsvorrichtung 26 oder einem Druckwerk. Die Lackauftragsvorrichtung 26 wird von einer, in Figur 3 von rechts, Materialbahn 27 durchlaufen. Nach dem Aufbringen eines Lacks in der Lackauftragsvorrichtung 26 durchläuft die Materialbahn 27 den Prallstrahltrockner 25. Am Ende des Durchlaufs erfolgt eine Umlenkung um eine Umlenkrolle 28 in den Prallstrahltrockner 25 hinein. FIG. 3 again shows an impingement jet dryer 25, arranged above a paint application device 26 or a printing unit. The paint application device 26 is of a, in FIG. 3 from the right, pass through web 27. After the application of a paint in the paint application device 26, the material web 27 passes through the impact jet dryer 25. At the end of the pass, a deflection takes place about a deflection roller 28 into the impact jet dryer 25.

Innerhalb des Prallstrahltrockners 25 ist in einem thermisch isolierenden Gehäuse 29 eine Vorrichtung 30 platzsparend angeordnet.Within the impingement jet dryer 25, a device 30 is arranged in a space-saving manner in a thermally insulating housing 29.

In der Vorrichtung 30 wird, wie erläutert, die Materialbahn 27 mehrfach umgelenkt, so dass mit Austritt derselben aus der Vorrichtung 30 eine ausreichende Vernetzung des aufgebrachten Lacks erfolgt ist. Es kann dann die Materialbahn 27 mit Austritt aus der Vorrichtung 30 um eine Umlenkrolle 31 und weitere Umlenkrollen umgelenkt über die Oberseite des Prallstrahltrockners 25 gem. Pfeil 32 für eine weitere Verarbeitung abgeführt werden.In the device 30, as explained, the material web 27 is deflected several times, so that with the exit thereof from the device 30, a sufficient cross-linking of the applied lacquer has taken place. It can then the material web 27 with the exit from the device 30 to a deflection roller 31 and further deflection rollers deflected over the top of the impingement jet dryer 25 gem. Arrow 32 are discharged for further processing.

Neben der platzsparenden Anordnung der Vorrichtung 30 innerhalb des Prallstrahltrockners 25 kann diese Ausbildung thermische Vorteile aufweisen, wenn die Temperaturdifferenzen zwischen der Temperatur im Inneren des Prallstrahltrockners 25 von beispielsweise 150° und der im Inneren der Vorrichtung 30 von beispielsweise 200° gering ist, da dann die thermische Isolierung durch das Gehäuse 29 vergleichsweise gering ausgebildet sein kann.In addition to the space-saving arrangement of the device 30 within the impingement jet dryer 25, this embodiment may have thermal advantages, if the temperature differences between the temperature inside the impingement jet dryer 25 of, for example, 150 ° and that inside the device 30, for example, 200 ° low, then the thermal insulation by the housing 29 may be made comparatively small.

Ein weiterer Vorteil dieser Maßnahmen besteht darin, dass das Äußere des Gehäuses 29 als Träger für Führungs- und/oder Trocknungsmittel wie Düsen oder Leitungen des Prallstrahltrockners 25 herangezogen werden kann, hier angedeutet durch Führungsrollen 33.Another advantage of these measures is that the exterior of the housing 29 can be used as a carrier for guiding and / or drying means such as nozzles or lines of the impingement jet dryer 25, indicated here by guide rollers 33.

Figur 4 zeigt ebenfalls in einem Ausschnitt eine Druck- und Lackieranlage. FIG. 4 also shows a section of a printing and varnishing plant.

Eine Materialbahn 35 durchläuft eine Lackauftragsvorrichtung 36 in Pfeilrichtung, um danach in einen Trockner 37 einzutreten. Der Trockner 37 und das Gehäuse 38 der Vorrichtung 39 für ein Vernetzen des Auftrags weisen eine gemeinsame Wand 40 auf, die mit Mitteln für das Führen und Trocknen der Materialbahn 35 versehen ist, angedeutet durch Rollen 41.A material web 35 passes through a paint application device 36 in the direction of arrow, in order then to enter a dryer 37. The dryer 37 and the housing 38 of the device 39 for cross-linking the application have a common wall 40 which is provided with means for guiding and drying the material web 35, indicated by rollers 41.

An der Eintrittsöffnung 42 des Gehäuses 38 ist eine erste Umlenkrolle 43 der Vorrichtung 39 für die Materialbahn 35 angeordnet. Innerhalb der Vorrichtung 39 wird die Materialbahn 35 dann fünffach umgelenkt, um dann durch eine Austrittsöffnung 44 auszutreten. Um zwei weitere Umlenkrollen 45,46 wird dann die Materialbahn 35 über die Vorrichtung 39 und den Trockner 37 den nachfolgenden Arbeitsstationen zugeführt.At the inlet opening 42 of the housing 38, a first deflection roller 43 of the device 39 for the material web 35 is arranged. Within the device 39, the material web 35 is then diverted fivefold, in order then to exit through an outlet opening 44. To two further pulleys 45,46 then the web 35 is supplied via the device 39 and the dryer 37 to the subsequent workstations.

Ein Freiraum 47 zwischen der Umlenkrolle 43, den darunter liegenden Umlenkrollen 48,49 und der Gehäusewand 50 der Vorrichtung 39 erlaubt es, eine Materialbahn 51 durch die Vorrichtung 39 zu führen, ohne dass diese umgelenkt werden muss, beispielsweise für den Fall, dass keine Vernetzung erforderlich ist.A clearance 47 between the deflection roller 43, the underlying deflection rollers 48,49 and the housing wall 50 of the device 39 allows a material web 51 to pass through the device 39, without having to be deflected, for example, in the event that no networking is required.

Nach dem Austritt durch eine Austrittsöffnung 52 wird die Materialbahnen 51 erneut um eine Umlenkrolle 53 umgelenkt und wie die Materialbahn 35 von den Umlenkrollen 45,46 über die Vorrichtung 39 und den Trockner 37 abgeführt.After exiting through an outlet opening 52, the material webs 51 is deflected again around a deflection roller 53 and, like the material web 35, is removed from the deflection rollers 45, 46 via the device 39 and the dryer 37.

Figur 5 zeigt in einem Schnitt die prinzipielle Darstellung einer modulartig ausgebildeten Vorrichtung 55. Bei diesem Ausführungsbeispiel sind die Eintrittsöffnung 56 für eine Materialbahn 57 und die Austrittsöffnung 58 gegenüberliegend und auf unterschiedlichen Höhen angeordnet. Innerhalb der Vorrichtung 55 wird die Materialbahn 57 zehnmal umgelenkt. FIG. 5 shows in a section the basic representation of a module-like device 55. In this embodiment, the inlet opening 56 for a Material web 57 and the outlet opening 58 opposite and arranged at different heights. Within the device 55, the material web 57 is deflected ten times.

Durch thermisch isolierende Zwischenwände 59-61 werden vier unterschiedlich große Bereiche 62-65 voneinander abgeteilt, die unterschiedlich temperiert sind. So kann beispielsweise in Durchlaufrichtung gem. Pfeil der Materialbahn 57 gesehen, in einem ersten Bereich 62 eine Temperaturzone von 160°C eingerichtet sein, durch die Temperatur der Materialbahn 57 langsam auf die Vernetzungstemperatur von beispielsweise 200°C in dem zweiten Bereich 63 erhöht wird. In dem dritten Bereich 64 kann dann eine Abkühlung auf eine Temperatur von 120°C erfolgen und wird in dem vierten Bereich die Materialbahn 57 auf eine Austrittstemperatur von 80°C weiter abgekühlt.By thermally insulating partitions 59-61 four different sized areas 62-65 are separated from each other, which are different temperatures. Thus, for example, in the passage direction acc. Arrow the web 57 seen to be set up in a first region 62, a temperature zone of 160 ° C, is slowly increased by the temperature of the web 57 to the crosslinking temperature of, for example, 200 ° C in the second region 63. In the third region 64 can then be cooled to a temperature of 120 ° C and in the fourth region, the material web 57 is further cooled to an outlet temperature of 80 ° C.

Auch in der Vorrichtung 68 gemäß Figur 6 wird die Materialbahn 69 zehnmal umgelenkt. In der wiedergegebenen Seitenansicht erfolgt dort eine Umlenkung etwa U-förmig. Hierdurch kann die Verweildauer der Materialbahn 69 innerhalb der Vorrichtung 68 aufgrund der längeren Streckenführung erhöht werden, bevor diese etwa mittig die Vorrichtung 68 durch die Austrittsöffnung 70 verlässt.Also in the device 68 according to FIG. 6 the web 69 is deflected ten times. In the reproduced side view there is a deflection approximately U-shaped. As a result, the residence time of the material web 69 within the device 68 can be increased due to the longer routing before it leaves the device 68 through the outlet opening 70 approximately in the center.

Bei dem Ausführungsbeispiel einer Vorrichtung 73 nach Figur 7 wird nach Eintritt einer Materialbahn 74 durch eine Eintrittsöffnung 75 diese innerhalb der Vorrichtung 73 über eine Vielzahl von Rollen 76 geführt. Neben einem Andruck der Materialbahn 74 an die Rollen 76 aufgrund der Zugspannung sorgen durch Pfeile angedeutete Luftstrahlen für eine sichere Anlage. Diese Luftstrahlen können unterschiedlich temperiert sein, so dass die Temperatur der Materialbahn 74 bei einem Führen über die Rollen 76 erhöht wird, bevor in dem verbleibenden Raum 77 die Vernetzung abgeschlossen wird und die Materialbahn 74 durch eine Austrittsöffnung 78 die Vorrichtung 73 wieder verlässt. Gegebenenfalls können die Rollen 76 durch eine thermisch isolierende Wand noch von dem Raum 77 abgetrennt sein und kann so bspw. ein Trockner ausgebildet werden.In the embodiment of a device 73 according to FIG. 7 After entry of a material web 74 through an inlet opening 75, this is guided within the device 73 via a multiplicity of rollers 76. In addition to a pressure of the web 74 to the rollers 76 due to the tension provide indicated by arrows air jets for safe investment. These air jets can be tempered differently, so that the temperature of the web 74 is increased when guided over the rollers 76, before in the remaining space 77, the crosslinking is completed and the material web 74 leaves the device 73 again through an outlet opening 78. Optionally, the rollers 76 can still be separated from the space 77 by a thermally insulating wall, and thus, for example, a dryer can be formed.

Solches zeigt Figur 8, in der eine Materialbahn 80 über eine Vielzahl von Rollen 81 eines nur angedeuteten Trockners geführt ist. Durch Pfeile angedeutete Luftströme sorgen für Anpressdruck und Erwärmung. Nach Eintritt der Materialbahn 80 in das thermisch isolierte Gehäuse 82 der Vorrichtung 83 erfolgt dort, annähernd dreiecksförmig, eine Mehrfachumlenkung nach Art einer Spirale. An der letzten Umlenkrolle 84 wird die Richtung der ersten Spirale umgekehrt und wird die Materialbahn auf einer weiteren Spiralbahn aus der Vorrichtung 83 geführt.Such shows FIG. 8 in which a material web 80 is guided over a plurality of rollers 81 of an only indicated dryer. Arrows indicated by arrows provide contact pressure and heating. After entry of the material web 80 into the thermally insulated housing 82 of the device 83 takes place there, approximately triangular, a multiple deflection in the manner of a spiral. At the last deflection roller 84, the direction of the first spiral is reversed and the material web is guided on a further spiral path out of the device 83.

Figur 9 zeigt schematisch und beispielhaft eine Lackieranlage, in der von einer Rolle 87 eine Materialbahn 88 abgezogen wird. In einer Auftragsvorrichtung 89 erfolgt beispielsweise ein Lackauftrag und wird hernach die mit dem Lack versehene Materialbahn 90 einer Vielzahl von Schwebetrocknern 91 zugeführt. Waren ursprünglich sechs Schwebetrockner in einer linearen Anordnung vorgesehen, wurde, in Durchlaufrichtung der Materialbahn 90, der vierte Schwebetrockner durch eine Vorrichtung 92 für eine Vernetzung des Lackauftrags ersetzt. Selbstverständlich kann ein Austausch eines Schwebetrockners oder einer anderen Trocknungsvorrichtung durch eine Vorrichtung nach der Erfindung auch an anderer Stelle erfolgen. FIG. 9 shows schematically and by way of example a painting in which a web 87 of a web 88 is withdrawn. In a coating device 89, for example, a coating application is carried out and afterwards the material web 90 provided with the coating material is fed to a large number of floating dryers 91. Originally six floating dryers were provided in a linear arrangement, was replaced in the direction of passage of the web 90, the fourth floating dryer by a device 92 for crosslinking of the paint job. Of course, an exchange of a floating bed dryer or other drying device by a device according to the invention also take place elsewhere.

Nach Verlassen der Vorrichtung 92 erfolgt eine Nachtrocknung der Materialbahn in zwei weiteren Schwebetrocknern 93, bevor die dann getrocknete Materialbahn 94 auf einer weiteren Rolle 95 erneut aufgewickelt wird.After leaving the device 92, the material web is subsequently dried in two further flotation dryers 93, before the then dried material web 94 is rewound on a further roller 95.
