Abstract

The method involves rolling a surface finished sheet metal strip (1) applied with protection layer (2). The protection layer, arranged on the metal strip, is partly cut in the predetermined areas. The cutting of the protection layer is carried out with a cutting line, which moves perpendicularly on the surface of the metal strip. The cutting line runs partly inclined to a transport device of the metal strip. The metal strip is rolled to a profile strand. An independent claim is also included for a profile system with a line arranged roll pair.

Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Profilen durch Rollformen eines oberflächenendbehandelten, mit Schutzfolie bezogenen Blechbands, wobei die auf dem Blechband angeordnete Schutzfolie zumindest bereichsweise eingeschnitten wird. Ferner betrifft die Erfindung auch eine Profilieranlage mit in einer Linie angeordneten Rollenpaaren zur Herstellung von Profilen aus oberflächenendbehandeltem, mit Schutzfolie bezogenem Blechband durch Rollformen.The invention relates to a method for producing profiles by roll forming a surface-treated, covered with protective sheet metal strip, wherein the arranged on the metal strip protective film is at least partially cut. Furthermore, the invention also relates to a profiling with arranged in a line pairs of rollers for the production of profiles from surface-treated, covered with protective sheet metal strip by roll forming.

Verfahren zum Herstellen von Profilen durch Rollformen von Blechbändern sowie Profilieranlagen zur Durchführung solcher Verfahren sind bereits seit langem bekannt. Die als Ausgangsmaterial eingesetzten Blechbänder sind dabei üblicherweise mit Schutzfolien bezogen, um bei den nachfolgenden Verarbeitungsschritten ein Verkratzen der Oberfläche des Blechbands zu vermeiden. Üblicherweise werden diese Schutzfolien erst vom Endverbraucher abgezogen, um auch während des Transports zum Endverbraucher noch einen Schutz der Oberfläche der Profile zu gewährleisten.Processes for producing profiles by roll forming of metal strips and profiling systems for carrying out such processes have been known for a long time. The metal strips used as starting material are usually covered with protective films in order to avoid scratching the surface of the metal strip in the subsequent processing steps. Usually, these protective films are only deducted by the end user to ensure even during transport to the end user nor a protection of the surface of the profiles.

Es ist ferner bekannt, dass diese Verfahren einen Schritt umfassen können, in dem die Schutzfolie in Randbereichen bzw. in Bereichen in Längserstreckung des Blechbands beispielsweise dort, wo das Blechband verschweißt werden soll, durchgeschnitten und entfernt werden kann. Dies erfolgt üblicherweise dadurch, dass vor dem ersten Rollenpaar zur Umformung des Blechbandes Schneidräder angeordnet sind, mit denen die Schutzfolie eingeschnitten wird. Über weitere Rollen wird der abgeschnittene Folienstreifen abgezogen und aufgewickelt.It is also known that these methods may comprise a step in which the protective film can be cut and removed in peripheral regions or in regions in the longitudinal extent of the metal strip, for example where the metal strip is to be welded. This is usually done in that prior to the first pair of rollers for forming the metal strip cutting wheels are arranged with which the protective film is cut. The cut film strip is pulled off and wound up using further rollers.

Es kann aber auch erforderlich sein, die Schutzfolie in anderen Bereichen des Profils zu entfernen, beispielsweise um weitere Bauteile oder Aufkleber anzubringen. Das Ausschneiden einzelner Bereiche der Schutzfolie, das auch Schnitte quer zur Transportrichtung des Bandes erfordert, erfolgt üblicherweise manuell mit Hilfe von Schablonen nach dem Umformen des Blechbandes. Dieses Ausschneiden ist daher relativ aufwändig und zeitintensiv, auch kann die Genauigkeit darunter leiden.But it may also be necessary to remove the protective film in other areas of the profile, for example, to attach more components or stickers. The cutting out of individual areas of the protective film, which also requires cuts transversely to the transport direction of the tape, is usually carried out manually with the aid of templates after the forming of the sheet metal strip. This cutting is therefore relatively complex and time-consuming, and the accuracy may suffer.

Aus der DE 10 2006 003 719 A1 ist bereits ein Rollenwerkzeug zum Schneiden einer auf einem Werkstück aufgebrachten Folie bekannt. Das Rollenwerkzeug umfasst eine drehbar gelagerte Schneidrolle mit einem mittig umlaufenden Schneidmesser. Zum Ausschneiden von Folienstücken wird das Rollenwerkzeug beispielsweise in CNC-Stanzmaschinen eingesetzt und auf das mit der Folie bezogene Werkstück abgesetzt, bis das Schneidmesser die Folie an einer Stelle durchdrungen hat. Anschließend wird das Rollenwerkzeug relativ zum Werkstück längs der gewünschten Folienschneidkontur verlagert. Dabei rollt das Schneidmesser auf dem Werkstück ab und durchschneidet die Folie. Dieses Ausschneiden nimmt also längere Zeit in Anspruch.From the DE 10 2006 003 719 A1 A roller tool for cutting a film applied to a workpiece is already known. The roller tool comprises a rotatably mounted cutting roller with a centrally rotating cutting blade. For cutting of foil pieces, the roller tool is used for example in CNC punching machines and placed on the related to the film workpiece until the cutting blade has penetrated the film at one point. Subsequently, the roller tool is displaced relative to the workpiece along the desired foil cutting contour. The cutting blade rolls on the workpiece and cuts through the film. This cutting takes so long time to complete.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Verfahren zum Herstellen von Profilen durch Rollformen eines oberflächenendbehandelten, mit einer Schutzfolie bezogenen Blechbands zu ermöglichen, das einen Schritt umfasst, in dem die auf dem Blechband angeordnete Schutzfolie zumindest bereichsweise eingeschnitten wird, wobei dieses Verfahren einfach und kostengünstig sein soll und eine gute Genauigkeit der Position der ausgeschnittenen Bereiche ermöglicht.It is therefore the object of the present invention to provide a method for producing profiles by roll forming a surface-treated, covered with a protective sheet metal strip, comprising a step in which the arranged on the sheet metal strip is at least partially cut, this method is simple and cost-effective and allows a good accuracy of the position of the cut-out areas.

Hierzu ist erfindungsgemäß vorgesehen, dass das Verfahren die folgenden Schritte in der angegebenen Reihenfolge umfasst:

  • Zumindest teilweises Einschneiden der auf dem Blechband angeordneten Schutzfolie in vorgegebenen Bereichen, wobei das Einschneiden der Schutzfolie mit Schneidlinien erfolgt, die zum Einschneiden im Wesentlichen senkrecht auf die Oberfläche des Blechbands bewegt werden und zumindest teilweise quer zur Transportrichtung des Blechbands verlaufen;
  • Rollformen des Blechbands zu einem Profilstrang.
For this purpose, it is provided according to the invention that the method comprises the following steps in the order given:
  • At least partially cutting the arranged on the sheet metal protective film in predetermined areas, wherein the cutting of the protective film is carried out with cutting lines which are moved to cut substantially perpendicular to the surface of the metal strip and extend at least partially transverse to the transport direction of the metal strip;
  • Roll forming the sheet metal strip into a profile strand.

Das Verfahren zeichnet sich dadurch aus, dass nun auch der Schritt zum Ausschneiden einzelner Bereiche der Schutzfolie in das Verfahren integriert ist, also automatisiert durchgeführt werden kann, und keine manuellen Ausschneideschritte mehr erforderlich sind. Dadurch wird ein schnelleres und kostengünstigeres Herstellungsverfahren ermöglicht. Zudem wird das Einschneiden der Schutzfolie auf dem flachen Blechband durchgeführt, so dass keine Schnitte auf gebogenen Profilteilen bzw. Kanten durchgeführt werden müssen. Hierdurch wird eine höhere Genauigkeit der Position der Schnitte erreicht.The method is characterized in that now also the step for cutting individual areas of the protective film is integrated into the process, so it can be carried out automatically, and no more manual cutting steps are required. This allows a faster and cheaper manufacturing process. In addition, the cutting of the protective film is carried out on the flat sheet-metal strip, so that no cuts on curved profile parts or edges must be performed. As a result, a higher accuracy of the position of the cuts is achieved.

Zweckmäßigerweise kann vorgesehen werden, dass in einem Arbeitsschritt mit dem Einschneiden der Schutzfolie Aussparungen in das flache Blechband gestanzt werden. Beim Stanzen wird das Blechband durch das Stanzwerkzeug in einer definierten Position fixiert. Da das Einschneiden der Schutzfolie im gleichen Arbeitsschritt wie das Stanzen erfolgt, ist daher auch ein sehr genaues Einschneiden bis zu einer genau definierten Einschneidtiefe möglich.Appropriately, it can be provided that in one step with the cutting of the protective film recesses are punched in the flat sheet metal strip. When punching the sheet metal strip is fixed by the punch in a defined position. Since the cutting of the protective film in the same step as the punching Therefore, a very accurate cutting up to a well-defined incision depth is possible.

Eine Variante sieht vor, dass die Schutzfolie über ihre gesamte Dicke eingeschnitten wird. Dies geschieht beispielsweise dadurch, dass die Schneidlinien genau in Foliendicke vorstehen. Auf diese Weise wird die Schutzfolie durchgeschnitten, ohne die Oberfläche des Blechs zu zerkratzen. Auch ist dann ein sehr einfaches Abziehen der ausgeschnittenen Folienbereiche möglich.A variant provides that the protective film is cut over its entire thickness. This happens, for example, in that the cutting lines protrude exactly in film thickness. In this way, the protective film is cut without scratching the surface of the sheet. Also, then a very simple removal of the cut film areas is possible.

Noch eine weitere Verfahrensvariante sieht vor, dass das umgeformte Blechband zu einem geschlossenen Profilstrang verschweißt wird. Da auch die Schweißvorrichtung in die Arbeitslinie integriert werden kann, wird somit eine günstige und schnelle Herstellung der gewünschten Profile ermöglicht.Yet another variant of the method provides that the formed sheet metal strip is welded into a closed profile strand. Since the welding device can be integrated into the working line, thus a cheap and fast production of the desired profiles is possible.

Besonders bevorzugt ist vorgesehen, dass der Profilstrang durch Stanzen in einzelne Profile abgelängt wird. Durch das Stanzen wird ein glatter Schnitt mit einer sauberen Oberfläche an den Profilenden erzeugt. Es fallen keine bzw. wenig Abfallprodukte, wie beispielsweise Sägespäne an, die Trennung der Profile ist sehr exakt und sauber. Zudem erfolgt das Ablängen durch Stanzen sehr schnell.It is particularly preferred that the profile strand is cut to length by punching into individual profiles. Punching produces a smooth cut with a clean surface at the profile ends. There are no or little waste products, such as sawdust, the separation of the profiles is very accurate and clean. In addition, the cutting is done very quickly by punching.

Zweckmäßigerweise kann vorgesehen werden, dass die Schutzfolie in den zumindest teilweise ausgeschnittenen Bereichen entfernt wird. In diesen Bereichen können dann weitere Arbeitsschritte durchgeführt werden, während die restliche Profiloberfläche weiterhin geschützt bleibt, beispielsweise für einen Transport.Appropriately, it can be provided that the protective film is removed in the at least partially cut out areas. In these areas, further work steps can then be carried out while the rest of the profile surface remains protected, for example, for transport.

Bevorzugterweise können in den folienfreien Bereichen weitere Elemente angebracht werden. So ist es beispielsweise möglich, Aufkleber oder Aufdrucke auf die folienfreien Bereichen aufzubringen oder weitere Bauteile zu montieren. Somit können die Profile in eine verkaufsfertige Form gebracht werden, wobei die Oberflächen, die nicht bearbeitet werden müssen, bis zum Endverbraucher durch die Schutzfolie geschützt sind.Preferably, further elements can be applied in the foil-free regions. It is thus possible, for example, to apply stickers or imprints to the film-free areas or to mount further components. Thus, the profiles can be brought into a salable form, the surfaces that do not need to be processed are protected to the end user by the protective film.

Darüber hinaus bezieht sich die Erfindung auch auf eine Profilieranlage mit in einer Linie angeordneten Rollenpaaren zum Herstellen von Profilen aus oberflächenendbehandeltem, mit Schutzfolie bezogenem Blechband durch Rollformen. Die Profilieranlage zeichnet sich dadurch aus, dass in der Linie der Profilieranlage vor den Rollenpaaren im Wesentlichen senkrecht auf die Oberfläche des Blechbands bewegbare und zumindest teilweise quer zur Transportrichtung des Blechsbands schneidende Schneidlinien angeordnet sind.In addition, the invention also relates to a profiling with arranged in a line pairs of rollers for producing profiles from surface-treated, covered with protective sheet metal strip by roll forming. The profiling system is characterized in that in the line of profiling before the pairs of rollers substantially perpendicular to the surface of the metal strip movable and at least partially Intersecting cutting lines are arranged transversely to the transport direction of the metal strip.

Die Profilieranlage hat entsprechend den Vorteil, dass das Einschneiden der Schutzfolie vor dem Umformen des Blechbands zum Profil erfolgt. Das Einschneiden erfolgt also noch am flachen Blechband, wodurch die Schnitte an beliebiger Position angebracht werden können, also auch an solchen Positionen, die im späteren Profil einen Radius aufweisen oder auf einer Kante liegen. Es ist eine gute Positionierung der Schnitte mit guter Genauigkeit möglich.The Profilieranlage has the advantage that the cutting of the protective film takes place before forming the metal strip to the profile. The cutting is thus still on the flat sheet metal strip, whereby the cuts can be attached to any position, including at those positions that have a radius in the later profile or lie on one edge. Good positioning of the cuts is possible with good accuracy.

In einer bevorzugten Ausführungsform ist vorgesehen, dass vor den Rollenpaaren der Profilieranlage mindestens eine Stanzstation angeordnet ist und die Schneidlinien in mindestens ein Stanzwerkzeug der mindestens einen Stanzstation integriert sind. Durch die Stanzstation bzw. das Stanzwerkzeug wird das flache Blechband in einer genau definierten Position gehalten. Da die Schneidlinien in das Stanzwerkzeug integriert sind, werden sie mit dem Stanzwerkzeug bewegt, während das Blechband fixiert ist. Dadurch ist ein sehr genaues Einschneiden der Schutzfolie möglich, sowohl hinsichtlich der Position als auch hinsichtlich der Tiefe der Schnitte.In a preferred embodiment it is provided that at least one punching station is arranged in front of the roller pairs of the profiling system and the cutting lines are integrated into at least one punching tool of the at least one punching station. The punching station or the punching tool holds the flat sheet-metal strip in a precisely defined position. Since the cutting lines are integrated into the punching tool, they are moved with the punching tool while the sheet metal strip is fixed. This allows a very accurate cutting of the protective film, both in terms of position and in terms of the depth of the cuts.

In einer besonders bevorzugten Ausbildung kann vorgesehen werden, dass die Eindringtiefe der Schneidlinien genau der Dicke der auf dem Blechband angeordneten Schutzfolie entspricht. Somit wird also die Schutzfolie entlang der Schnittlinien vollständig durchgeschnitten, ohne dass dabei die Oberfläche des Blechs zerkratzt wird. Es ist dann ein leichtes Abziehen der ausgeschnittenen Folienbereiche möglich.In a particularly preferred embodiment it can be provided that the penetration depth of the cutting lines corresponds exactly to the thickness of the protective film arranged on the sheet metal strip. Thus, therefore, the protective film is completely cut along the cutting lines, without causing the surface of the sheet is scratched. It is then easy removal of the cut film areas possible.

Eine Variante sieht vor, dass die Eindringtiefe der Schneidlinien einstellbar ist. Somit ist das Einschneiden von verschiedenen Schutzfolien mit unterschiedlicher Dicke möglich.A variant provides that the penetration depth of the cutting lines is adjustable. Thus, the cutting of different protective films with different thickness is possible.

Fig. 1 shows a cross section through the flat sheet metal strip 1 perpendicular to the longitudinal extension with the protective film 2 mounted thereon before cutting the protective film 2 and the punching of recesses 3 in the metal strip 1. The sheet metal strip 1 is produced by splitting a Vorbandmaterials, at the same time the protective film 2 on the sheet metal strip 1 is applied to prevent the subsequent profiling of the sheet metal strip 1 scratching the surface. As a protective film 2, a plastic film is preferably used, for example a polyethylene film.

In Fig. 2 ist eine Draufsicht auf das mit der Schutzfolie 2 bezogene Blechband 1 nach dem Einschneiden der Schutzfolie 2 und nach dem Stanzen von Aussparungen 3, 3.1, 3.2, 3.3 in das Blechband 1 dargestellt. Die Figur 2 zeigt dabei nur einen Ausschnitt aus dem Blechband 1 in Längsrichtung des Blechbands 1, wobei die Verbindungsstelle zwischen zwei Profilen 6 gezeigt ist. Der gestrichelte Bereich 5 stellt die Trennlinie dar, entlang derer das Blechband 1 nach dem Umformen zum Profilstrang 14 in einzelne Profile 6 getrennt wird. Das Ablängen des Profilsstrangs 14 in einzelne Profile 6 erfolgt vorzugsweise durch einen Stanzvorgang. Dabei greifen die Stanzmesser in die Aussparungen 3 ein. Die Aussparungen 3.1 dienen zur Aufnahme von Befestigungsmitteln zur Befestigung weiterer Bauteile an dem Profil 6. Auch in den Aussparungen 3.2 und 3.3 können weitere Bauteile am Profil befestigt werden. Die auf dem Blechband 1 angebrachte Schutzfolie 2 ist entlang der Schnitte 4.1, 4.2 bzw. Bereiche 16.1, 16.2 zumindest teilweise durchgeschnitten, so dass die in diesen Bereichen 16.1, 16.2 liegende Schutzfolie 2 leicht abgezogen werden kann. In diesen Bereichen 16.1, 16.2 können nach dem Abziehen der Schutzfolie 2 weitere Elemente angebracht werden. So ist es beispielsweise denkbar, Aufkleber in die Bereiche 16.1, 16.2 zu kleben oder weitere Bauteile daran zu befestigen.In Fig. 2 is a plan view of the covered with the protective film 2 sheet metal strip 1 after cutting the protective film 2 and after punching recesses 3, 3.1, 3.2, 3.3 shown in the sheet metal strip 1. The FIG. 2 shows only a section of the sheet metal strip 1 in the longitudinal direction of the sheet metal strip 1, wherein the connection point between two profiles 6 is shown. The dashed area 5 represents the dividing line, along which the sheet metal strip 1 is separated after forming into profile strand 14 into individual profiles 6. The cutting of the profile strand 14 into individual profiles 6 is preferably carried out by a punching process. The punching blades engage in the recesses 3. The recesses 3.1 serve to receive fastening means for fastening further components to the profile 6. Also in the recesses 3.2 and 3.3 further components can be attached to the profile. The protective film 2 attached to the sheet-metal strip 1 is at least partially cut through along the sections 4.1, 4.2 or areas 16.1, 16.2, so that the protective film 2 lying in these areas 16.1, 16.2 can easily be peeled off. In these areas 16.1, 16.2 2 further elements can be attached after peeling off the protective film. Thus, it is conceivable, for example, to stick stickers in the areas 16.1, 16.2 or to fasten further components thereto.

Fig. 3 zeigt ein fertiges Profil 6 nach dem Umformen mit darin angebrachten Endkappen 7. Die Endkappen 7 werden in den Bereichen 4.1 angebracht, in denen die Aussparungen 3.1, 3.2, 3.3 vorgesehen wurden und nachdem die Schutzfolie 2 in diesem Bereich 4.1 abgezogen wurde. Auch in dem Bereich 16.2 wurde die Schutzfolie abgezogen, dort können beispielsweise Aufkleber angebracht werden. Auf der verbleibenden Oberfläche des Profils 6 ist immer noch Schutzfolie 2 angeordnet, so dass diese Oberfläche beim Transport nicht beschädigt werden kann. Diese Schutzfolie kann dann vom Endverbraucher abgezogen werden. Fig. 3 shows a finished profile 6 after forming with end caps mounted therein 7. The end caps 7 are mounted in the areas 4.1, in which the recesses 3.1, 3.2, 3.3 were provided and after the protective film 2 was peeled off in this area 4.1. Also in the area 16.2 the protective film was peeled off, where, for example, stickers can be applied. On the remaining surface of the profile 6 protective film 2 is still arranged, so that this surface can not be damaged during transport. This protective film can then be removed from the end user.

Fig. 4 zeigt eine Profilieranlage 8 zum erfindungsgemäßen Herstellen von Profilen 6. Das mit der Schutzfolie 2 bezogenen Blechband 1 wird als Coil 9 bereitgestellt und der Profilieranlage 8 zugeführt. In der Profilieranlage 8 sind die einzelnen Bearbeitungsstationen in einer Linie hintereinander angeordnet. Das Blechband 1 mit der darauf angeordneten Schutzfolie 2 wird zuerst in eine Stanzstation 10 geführt. Es können auch mehrere Stanzstationen hintereinander angeordnet sein. In der Stanzstation 10 sind mindestens ein Stanzwerkzeug 11 und Schneidlinien 12 angeordnet. Als Schneidlinien 12 werden die Messer bzw. Klingen bezeichnet, mit denen die Schutzfolien 2 durchgeschnitten wird. Diese Messer bzw. Klingen können eine beliebige Form haben und beispielsweise eine geschlossene Form bilden, so dass sie genau der zu entfernenden Folienkontur entsprechen. Die Schneidlinien 12 können in das Stanzwerkzeug 11 integriert sein. Fig. 4 shows a profiling system 8 for producing profiles 6 according to the invention. The sheet metal strip 1, which is covered by the protective film 2, is provided as a coil 9 and fed to the profiling plant 8. In the profiling system 8, the individual processing stations are arranged in a line one behind the other. The sheet-metal strip 1 with the protective film 2 arranged thereon is first guided into a stamping station 10. It can also be arranged in succession punching stations. In the punching station 10 at least one punch 11 and cutting lines 12 are arranged. As cutting lines 12, the blades or blades are referred to, with which the protective films 2 is cut. These blades or blades may have any shape and form, for example, a closed shape, so that they correspond exactly to the foil contour to be removed. The cutting lines 12 may be integrated into the punching tool 11.

In der Stanzstation 10 werden Aussparungen 3, 3.1, 3.2, 3.3 in das Blechband 1 gestanzt und mithilfe der Schneidlinien 12 Schnitte 4.1, 4.2 in die Schutzfolie 2 eingebracht.In the punching station 10 recesses 3, 3.1, 3.2, 3.3 are punched into the sheet metal strip 1 and 12 cuts 4.1, 4.2 introduced by means of the cutting lines in the protective film 2.

In der Linie der Profilieranlage 8 sind hinter der Stanzstation 10 die Rollenpaare 13 zum Umformen des flachen Blechbands 1 in einen Profilstrang 14 angeordnet. Im Anschluss an die Rollenpaare 13 kann eine Schweißstation (nicht dargestellt) angeordnet sein, mit der das umgebogene Blechband zu einem geschlossenen Profilstrang 14 verschweißt wird.In the line of Profilieranlage 8 behind the punching station 10, the roller pairs 13 are arranged for forming the flat sheet metal strip 1 in a profile strand 14. Following the pairs of rollers 13, a welding station (not shown) may be arranged, with which the bent sheet-metal strip is welded into a closed profile strand 14.

In der Linie der Profilieranlage 8 befindet sich hinter den Rollenpaaren 13 bzw. der Schweißanlage eine Abtrennstation 15. In dieser Abtrennstation 15 wird der Profilstrang 14 in die gewünschten Profile 6 abgelängt. Dies kann beispielsweise durch Stanzen erfolgen.In the line of Profilieranlage 8 is behind the pairs of rollers 13 and the welding system, a separation station 15. In this separation station 15 of the profile strand 14 is cut to the desired profile 6. This can be done for example by punching.

Im Folgenden wird nun anhand von Fig. 4 das Verfahren zur Herstellung von Profilen 6 beschrieben. Von dem Coil 9 wird das mit der Schutzfolie 2 bezogene Blechband 1 abgewickelt und der Stanzstation 10 zugeführt. Das Blechband 1 kann beispielsweise aus geschliffenem, rostbeständigem CrNi-Material bestehen, so dass optische, statische und korrosive Anforderungen, auch für den Außenbereich, erfüllt werden. Mithilfe der in der Stanzstation 10 angeordneten Stanzwerkzeuge 11 werden Aussparungen 3, 3.1, 3.2, 3.3 in das Blechband 1 gestanzt. Im gleichen Arbeitsschritt, in dem die Aussparungen 3, 3.1, 3.2, 3.3 gestanzt werden, werden die Schneidlinien 12 bewegt. Mit den Schneidlinien 12 werden Schnitte 4.1, 4.2 in die Schutzfolie 2 eingebracht. Dazu werden die Schneidlinien 12 senkrecht zur Oberfläche des Blechbands 1 von oben auf das Blechband 1 bewegt. Die Schneidlinien 12 sind zumindest teilweise quer zur Transportrichtung des Blechbands 1 angeordnet. Vorzugsweise stehen die Schneidlinien 12 genau soweit vor, dass sie genau der Dicke der auf dem Blechband 1 angeordneten Schutzfolie 2 entsprechen. Dadurch wird beim Absenken der Schneidlinien 12 die auf dem Blechband 1 angeordnete Schutzfolie 2 vollständig durchschnitten, die Oberfläche des Blechbandes 1 aber nicht beschädigt. Um das Einschneiden verschiedener Schutzfolien zu ermöglichen, kann auch vorgesehen werden, dass die Eindringtiefe der Schneidlinien 12 einstellbar ist. Bei dem Stanzvorgang wird das Blechband 1 in der Stanzstation 10 in einer genau definierten Position gehalten. Da die Schneidlinien 12 in dem gleichen Arbeitsgang wie die Stanzwerkzeuge 11 bewegt werden, sich das Blechband 1 sich also in der genau definierten Stanzposition befindet, ist es möglich die Eindringtiefe der Schneidlinien 12 in die Schutzfolie 2 genau festzulegen. Somit kann ein sehr genaues Einschneiden der Schutzfolie 2 erfolgen. Es kann aber auch vorgesehen werden, dass keine Stanzstation in der Profilieranlage vorgesehen ist. Die Fixierung des Blechbands 1 zum Durchschneiden der Schutzfolie 2 wird dann über andere Mittel realisiert. Nach dem Durchführen des Schneide- und Stanzvorgangs wird das Blechband 1 mit der darauf angeordneten Schutzfolie 2 den Rollenpaaren 13 zum Profilieren zugeführt. Die ausgeschnittenen Folienbereiche 16.1, 16.2 befinden sich immer noch auf dem Blechband 1. Die Profilierstation 8 umfasst eine Mehrzahl von Rollenpaaren 13, mit denen das flache Blechband 1 mit der darauf angeordneten Schutzfolie 2 zu einem Profilstrang 14 umgeformt wird.The following will now be based on Fig. 4 the process for producing profiles 6 described. From the coil 9 related to the protective film 2 sheet metal strip 1 is unwound and fed to the punching station 10. The sheet-metal strip 1 may for example consist of ground, rust-resistant CrNi material, so that optical, static and corrosive requirements, also for outdoor use, are met. By means of the punching station 10 arranged punching tools 11 recesses 3, 3.1, 3.2, 3.3 are punched into the sheet metal strip 1. In the same step in which the recesses 3, 3.1, 3.2, 3.3 are punched, the cutting lines 12 are moved. With the cutting lines 12 sections 4.1, 4.2 are introduced into the protective film 2. For this purpose, the cutting lines 12 are moved perpendicular to the surface of the metal strip 1 from above on the sheet metal strip 1. The cutting lines 12 are at least partially transverse to the transport direction of the metal strip 1 arranged. Preferably, the cutting lines 12 are exactly so far that they correspond exactly to the thickness of the arranged on the sheet metal strip 1 protective film 2. As a result, when the cutting lines 12 are lowered, the protective film 2 arranged on the sheet-metal strip 1 is completely cut through, but the surface of the sheet-metal strip 1 is not damaged. In order to enable the cutting of different protective films, it can also be provided that the penetration depth of the cutting lines 12 is adjustable. In the punching operation, the sheet metal strip 1 is held in the punching station 10 in a precisely defined position. Since the cutting lines 12 are moved in the same operation as the punching tools 11, so that the sheet metal strip 1 is in the precisely defined punching position, it is possible to precisely define the penetration depth of the cutting lines 12 into the protective film 2. Thus, a very accurate cutting of the protective film 2 can take place. However, it can also be provided that no punching station is provided in the profiling system. The fixation of the metal strip 1 for cutting through the protective film 2 is then realized by other means. After performing the cutting and punching operation, the sheet metal strip 1 is supplied with the protective film 2 arranged thereon to the roller pairs 13 for profiling. The cut-out film areas 16.1, 16.2 are still on the sheet-metal strip 1. The profiling station 8 comprises a plurality of roller pairs 13, with which the flat sheet-metal strip 1 with the protective film 2 arranged thereon is formed into a profile strand 14.

Vor den Rollenpaaren 13 können ferner noch Schneidrollen angeordnet sein, mit denen die Schutzfolie in Randbereichen entlang der Transportrichtung des Blechbandes 1 durchgeschnitten wird und anschließend mithilfe weiterer Rollen abgezogen und aufgewickelt wird. In diesen Bereichen kann dann nach dem Umformen eine Schweißnaht angebracht werden. Dazu ist hinter den Rollenpaaren 13 eine Schweißstation (nicht dargestellt) angeordnet, in der das umgeformte Blechband 1 zu einem geschlossenen Profilstrang 14 verschweißt wird.Before the pairs of rollers 13 cutting rollers can also be arranged, with which the protective film is cut in edge regions along the transport direction of the metal strip 1 and then withdrawn and wound up using other roles. In these areas can then be applied after forming a weld. For this purpose, a welding station (not shown) is arranged behind the pairs of rollers 13, in which the formed sheet metal strip 1 is welded into a closed profile strand 14.

Der geschlossene Profilstrang 14 wird in der Abtrennstation 15 zu Profilen 6 abgelängt. Vorzugsweise erfolgt dieses Ablängen durch Stanzen, da dadurch eine saubere Schnittfläche entsteht und das Stanzen schnell durchgeführt werden kann.The closed profile strand 14 is cut to 6 profiles in the separation station. Preferably, this cutting is done by punching, as this creates a clean cut surface and punching can be performed quickly.

Die Profile 6 können anschließend weiterverarbeitet werden. So können die in Fig. 3 dargestellten Endkappen 7 an den Enden der Profile 6 angebracht werden. Dazu wird die Schutzfolie 2 in den vorgeschnittenen Bereichen 16.1 abgezogen und die Endkappen werden an den Aussparungen 3.1, 3.2, 3.3 angebracht. Weiterhin können auf den Profilen 6 beispielsweise noch Aufkleber angebracht werden. Dazu wird die Schutzfolie 2 in dem vorgeschnittenen Bereich 16.2 abgezogen und der Aufkleber auf der Oberfläche des Profils 6 angebracht. In den übrigen Bereichen des Profils 6 ist weiterhin die Schutzfolie 2 angeordnet, so dass die Profile 6 auch beim Transport noch vor Kratzern oder anderen Beschädigungen an der Oberfläche geschützt sind. Der Endverbraucher kann dann die Schutzfolie 2 vollständig abziehen.The profiles 6 can then be further processed. So can the in Fig. 3 shown end caps 7 are attached to the ends of the profiles 6. For this purpose, the protective film 2 is peeled off in the precut areas 16.1 and the end caps are attached to the recesses 3.1, 3.2, 3.3. Furthermore, on the profiles 6, for example, stickers are still attached. For this purpose, the protective film 2 is peeled off in the precut area 16.2 and the sticker is applied to the surface of the profile 6. In the other areas of the profile 6, the protective film 2 is further arranged, so that the profiles 6 are protected against scratches or other damage to the surface during transport. The end user can then remove the protective film 2 completely.
