Abstract

The aim of the invention is to develop methods, devices and support profiles that are configured to match the method and device, said profiles being used to attach a support section for rubber seals to automobile body parts in the shortest possible time with the minimum of tools and personnel. In addition, the methods and devices should be adaptable in such a way that modifications to the geometry of the sealing section and in particular to the contours of the body parts can be accommodated without long stoppages of the assembly line. The support sections and connecting regions must also mould to all the contours of the automobile bodywork, in particular the corner regions, and must permit the attachment of various sealing regions and the application of extreme detachment forces. To achieve these aims, the support section (1, 9) for the sealing section (11) is attached to the support surface (4) in one single operation. The sub-steps of said operation are carried out by an industrial robot. In a preferred embodiment of the invention, adhesive is applied to the support section (1, 9) during the production of the latter.

Description

Verfahren und Vorrichtung zum Aufbringen von Trägerprofilen für Gummidichtungen an Automobilkarosserieteilen und Trägerprofil Method and device for applying carrier profiles for rubber seals to automobile body parts and carrier profile
Die vorliegende Erfindung betrifft Verfahren und Vorrichtungen zum Aufbringen von Trägerprofilen für Dichtungsprofile an Automobilkarosserieteilen sowie selbstklebende Trägerprofile, die besonders zum Aufbringen mittels dieser Verfahren und Vorrichtungen geeignet sind. Desweiteren umfaßt die Erfindung einen Verbindungsbereich, der einem dieser Trägerprofile zugeordnet ist und mittels dessen der Dichtbereich des Dichtungsprofils auf das Trägerprofil gesteckt wird.The present invention relates to methods and devices for applying carrier profiles for sealing profiles to automobile body parts and self-adhesive carrier profiles which are particularly suitable for application by means of these methods and devices. Furthermore, the invention comprises a connection area which is assigned to one of these support profiles and by means of which the sealing area of the sealing profile is plugged onto the support profile.
Bei der Herstellung von Automobilen ist als vorteilhaft anzusehen, Dichtungen, die im Bereich von Türen oder Kofferraumverschlüssen den Fahrgastinnenraum oder den Kofferrraum vor eindringender Feuchtigkeit schützen, nicht direkt auf der Trägerfläche, also auf dem Blechteil, nämlich der Tür oder dem Kofferraumverschluß, zu befestigen, sondern vielmehr zunächst ein Trägerprofil auf der Trägerfläche zu befestigen und darauf dann das Dichtungsprofil aufzustecken.In the manufacture of automobiles, it should be considered advantageous not to fasten seals that protect the passenger compartment or the trunk in the area of doors or trunk locks from the ingress of moisture, not directly on the carrier surface, i.e. on the sheet metal part, namely the door or the trunk lock, Rather, first attach a support profile to the support surface and then attach the sealing profile.
Dichtungsprofile an Türen oder Kofferraumverschlüssen obliegen einem Verschleiß oder können durch Beschädigung ihre Funktion verlieren. Deshalb ist es wichtig, daß diese Dichtungsprofile ohne großen Aufwand und ohne Beschädigung der Trägerfläche gewechselt werden können. Daher ist es vorteilhaft, das Dichtungsprofil auf ein Trägerprofil aufzustecken und das Trägerprofil fest mit der Trägerfläche, beispielsweise der Türkarosserie zu verbinden, beispielsweise zu verkleben. Im Normalfall wird nur das Dichtungsprofil versagen und das Trägerprofil weiterverwendet werden können. Das Dichtungsprofil kann dann vom Trägerprofil abgezogen werden und durch ein neues ersetzt werden. Durch diesen Vorgang wird die Trägerfläche nicht beschädigt und zum Austausch des Dichtungsprofils werden keine Spezialwerkzeuge, Kleber oder sonstige aufwendigen Verbindungstechniken benötigt.Sealing profiles on doors or trunk locks are subject to wear or can lose their function due to damage. It is therefore important that these sealing profiles can be changed without great effort and without damaging the support surface. It is therefore advantageous to plug the sealing profile onto a carrier profile and to firmly bond the carrier profile to the carrier surface, for example the door body, for example by gluing. In the normal case, only the sealing profile will fail and the carrier profile can continue to be used. The sealing profile can then be removed from the carrier profile and replaced with a new one. This process does not damage the support surface and no special tools, glue or other complex connection techniques are required to replace the sealing profile.
Desweiteren kann ein Trägerprofil zum Aufstecken verschiedenartiger Dichtungsformen oder Dichtungsgrößen verwendet werden. Bei Wechsel oder Varianten des Automobilmodells, die mit einer Änderung der Form oder Länge des Dichtungsprofils verbunden sind, kann in gewissen Grenzen immer noch das gleiche Trägerprofil und der gleiche Verbindungsbereich verwendet werden. Auf verschiedenförmige oder verschiedengroße Spalten, die abzudichten sind, kann durch Anpassung der Größe des Dichtbereiches des Dichtungsprofils unter Beibehaltung des Verbindungsbereiches und des Trägerprofils reagiert werden.Furthermore, a carrier profile can be used to attach different types of seals or sizes. When changing or variants of the automobile model, which are associated with a change in the shape or length of the sealing profile, the same carrier profile and the same can still be used within certain limits Connection area can be used. Different sized or different sized gaps to be sealed can be reacted to by adapting the size of the sealing area of the sealing profile while maintaining the connection area and the support profile.
Diese Vorteile kommen insbesondere zum Tragen, wenn Trägerprofil und Dichtungs- profil als Meterware eingesetzt werden können, da dann sehr schnell durch einfaches Schneiden die geforderte Länge erzielt werden kann.These advantages come into play particularly when the carrier profile and sealing profile can be used by the meter, since the required length can then be achieved very quickly by simple cutting.
Aus der DE 19808044 C 2 ist eine solche Anordnung zum losen Verbinden wenigstens zweier Bauelemente mittels Steckverbindung, beispielsweise zum Verbinden eines Dichtungsprofils mit einer Kraftfahrzeugkarosserie bekannt. Vorzugsweise wird hier das Fußbauteil (3) an dem ersten Bauelement (2) durch Anformen befestigt. Das Anformen kann durch eine geeignete Vergußtechnik erfolgen.Such an arrangement for the loose connection of at least two components by means of a plug connection, for example for connecting a sealing profile to a motor vehicle body, is known from DE 19808044 C 2. The foot component (3) is preferably attached to the first component (2) by molding. The molding can be done using a suitable casting technique.
Desweiteren beschreibt die DE 19802203 A 1 ein Verfahren zum Herstellen einer Verbindung eines Bauteils mit einem Bauelement. Hier wird zwischen Bauteil (2) und Bauelement (1) ein Zwischenhalter (8) aus aushärtender Vergußmasse (3) eingebracht. Damit wird eine lösbare Verbindung zwischen Bauelement und Bauteil über den Zwischenhalter hergestellt. Zur Verstärkung dieser Verbindung kann der Zwischenhalter mit dem Bauelement verklebt werden, indem die Vergußmasse in einen Kleberauftrag gesetzt wird. Bei diesem Verfahren wird das Bauteil an das Bauelement angesetzt. Zur Fixierung des Bauteils dient eine derartige Halteeinrichtung, die die Lage von Bauteil und Bauelement zueinander so lange fixiert, bis die zwischen Bauteil und Bauelement eingebrachte Vergußmasse zu einem diese Teile miteinander verbindenden Zwischenträger aushärtet.Furthermore, DE 19802203 A 1 describes a method for establishing a connection between a component and a component. An intermediate holder (8) made of hardening potting compound (3) is inserted between component (2) and component (1). This creates a releasable connection between the component and the component via the intermediate holder. To reinforce this connection, the intermediate holder can be glued to the component by placing the sealing compound in an adhesive application. With this method, the component is attached to the component. A holding device of this type is used to fix the component, which fixes the position of the component and the component relative to one another until the potting compound introduced between the component and the component hardens to form an intermediate carrier connecting these parts to one another.
Ein ähnliches Verfahren beschreibt die DE 19714242 A Hier wird auf das erste Bauteil ein Kleber aufgetragen, auf diesen ein Verbindungsteil gesetzt und darauf ein zweites Bauteil aufgebracht, vorzugsweise aufgeklippt. Nach einer Weiterbildung der Erfindung soll Vergußmasse durch Durchbrechungen im ersten Bauteil eingefüllt werden. Die Vergußmasse soll die Formgebung des Verbindungsteiles umgreifen bzw. hintergreifen, daß dadurch das Verbindungsteil am ersten Bauteil festgehalten wird. Das Verbindungsteil wird bei industrieller Anwendung in eine Haltevorrichtung eingelegt und gegen den mit einem Kleber versehenen Verbindungsbereich gedrückt und nach dem Eingeben der Vergußmasse so lange gehalten, bis die Vergußmasse ausgehärtet ist.A similar process is described in DE 19714242 A, in which an adhesive is applied to the first component, a connecting part is placed on it and a second component is applied, preferably clipped, onto it. According to a development of the invention, casting compound is to be filled in through openings in the first component. The potting compound should encompass or reach behind the shape of the connecting part in such a way that the connecting part is held on the first component. The connecting part is placed in a holding device in industrial application and against pressed the connection area provided with an adhesive and held after entering the potting compound until the potting compound has hardened.
Die Verwendung einer bei der Montage flüssig einzubringenden Vergußmasse führt jedoch dazu, daß der Hohlraum, in den die Vergußmasse eingebracht werden soll, beispielsweise der Raum zwischen Türkarosserie und Dichtung, gegen ungewollten Austritt der Vergußmasse abgedichtet sein muß, was mit einem gewissen Aufwand verbunden ist. Andererseits müssen in der Türkarosserie Öffnungen, beispielsweise in Form von Bohrungen geschaffen werden, durch die Vergußmasse in den Hohlraum eingeleitet werden kann. Diese Bohrungen setzen jedoch die Festigkeit der Karosserie herab, sind anfällig gegen Korrosion und die Herstellung der Bohrungen stellt einen zusätzlichen Arbeitsschritt bei der Montage des Automobils dar.However, the use of a potting compound to be introduced during assembly means that the cavity into which the potting compound is to be introduced, for example the space between the door body and the seal, must be sealed against unwanted escape of the potting compound, which is associated with a certain outlay. On the other hand, openings have to be made in the door body, for example in the form of bores, through which potting compound can be introduced into the cavity. However, these holes reduce the strength of the body, are susceptible to corrosion and the production of the holes represents an additional step in the assembly of the automobile.
Die Verwendung von Halteeinrichtungen oder Haltevorrichtungen führt zu weiteren Nachteilen. Die Haltevorrichtung ist auf das Dichtungs- bzw. Trägerprofil und insbesondere auf die Kontur der Tür abgestimmt. Geometrische Veränderungen dieser Teile führen daher dazu, daß die Haltevorrichtung nicht mehr verwendet werden kann und an die neue Geometrie angepaßt werden muß. Man benötigt daher auch für jede Modellvariante eine eigens konzipierte Haltevorrichtung. Hohe Investitionskosten sowie ein hoher Rüstaufwand bei der Umstellung zwischen verschiedenen Modellvarianten ist die Folge.The use of holding devices or holding devices leads to further disadvantages. The holding device is matched to the sealing or carrier profile and in particular to the contour of the door. Geometric changes to these parts therefore mean that the holding device can no longer be used and must be adapted to the new geometry. You therefore need a specially designed holding device for each model variant. The result is high investment costs and a high set-up effort when switching between different model variants.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Verfahren, eine Vorrichtung sowie an das Verfahren und an die Vorrichtung angepaßte Trägerprofile und Verbindungsbereiche zu entwickeln, mit deren Hilfe es gelingt, in möglichst kurzer Zeit, mit geringem Werkzeug- und Personalaufwand ein Trägerprofil für Dichtungsprofile an Automobilkarosserieteilen aufzubringen. Desweiteren sollen das Verfahren und die Vorrichtung derart anpassungsfähig sein, daß auf Änderungen in der Geometrie der Gummidichtung und insbesondere in der Kontur der Karosserieteile ohne lange Stillstandzeiten der Montagestraßen reagiert werden kann. Die Trägerprofile und Verbindungsbereiche müssen dem Verlauf der Automobilkarosserie an Türen und Kofferraumverschlüssen auch in den Eckbereichen folgen können und müssen das Aufbringen verschiedener Dichtbereiche und hohe Abzugskräfte ermöglichen. Die Aufgabe wird dadurch gelöst, daß das Aufbringen des Trägerprofils auf die Trägerfläche in einem Arbeitsgang bestehend aus einer raschen Abfolge zeitlich nur kurz zueinander versetzter Teilarbeitsschritte erfolgt. Die Teilarbeitsschritte werden von einem Industrieroboter durchgeführt. Die Bewegungen des Roboters werden der geometrischen Kontur der Trägerfläche, also der Türkarosserie oder des Kofferraumverschlusses, folgend programmiert. Auf einen Wechsel oder eine Variante des Automobilmodells kann dementsprechend durch Umprogrammierung der Bewegungen des Roboters schnell, das heißt ohne längere Produktionsunterbrechungen und ohne umfangreichen Wechsel der Montagewerkzeuge und damit ohne größere Kosten reagiert werden. Nach dem Aufbringen des Trägerprofiles kann dann das eigentliche Dichtungsprofil aufgesteckt werden.Proceeding from this, the object of the invention is to develop a method, a device, and support profiles and connection areas adapted to the method and the device, with the aid of which a support profile for sealing profiles can be achieved in the shortest possible time with little tool and personnel expenditure to be applied to automobile body parts. Furthermore, the method and the device should be adaptable in such a way that changes in the geometry of the rubber seal and in particular in the contour of the body parts can be reacted to without long downtimes on the assembly lines. The support profiles and connection areas must be able to follow the shape of the car body on doors and trunk locks in the corner areas as well, and must enable the application of various sealing areas and high pulling forces. The object is achieved in that the application of the support profile to the support surface takes place in one work step consisting of a rapid sequence of sub-work steps that are only briefly offset from one another. The partial work steps are carried out by an industrial robot. The movements of the robot are programmed according to the geometric contour of the carrier surface, i.e. the door body or the trunk lock. Accordingly, a change or a variant of the automobile model can be reacted to quickly by reprogramming the movements of the robot, that is to say without lengthy production interruptions and without extensive replacement of the assembly tools and thus without major costs. After the carrier profile has been applied, the actual sealing profile can then be attached.
Die Trägerprofile und die Verbindungsbereiche sind zum Aufbringen verschiedenartiger Dichtungsbereiche auf eine Automobilkarosserie geeignet; sei es, wie in der Figur 4 dargestellt, ein schlauchförmiger Dichtbereich aus Weichgummi oder eine Lippendichtung. Der Dichtbereich kann somit an verschiedene Anwendungen in Abhängigkeit von Spaltweite und -form angepaßt werden unter Beibehaltung des Trägerprofils und des Verbindungsbereiches.The carrier profiles and the connection areas are suitable for applying different types of sealing areas to an automobile body; be it, as shown in FIG. 4, a tubular sealing area made of soft rubber or a lip seal. The sealing area can thus be adapted to different applications depending on the gap width and shape while maintaining the support profile and the connection area.
In vorteilhafter Ausgestaltung der Erfindung wird das Trägerprofil schon bei dessen Herstellung mit einem Klebstoffsystem versehen. Erst unmittelbar vor dem Aufbringen des Trägerprofiles auf die Trägerfläche wird das Klebstoffsystem mittels einer Aktivierungseinheit zur Wirkung gebracht. Das Auslösen der Reaktion des Klebstoffsystems kann beispielsweise durch Zufuhr von Ultraviolett- oder Infrarotstrahlung oder durch Druck erfolgen. Dieses Verfahren hat den Vorteil, daß während der Montage, wo es aus Kostengründen von erheblicher Bedeutung ist, Zeit einzusparen und möglichst wenig Störungen im Verfahrensablauf aufzuweisen, kein Klebstoffsystem aufgetragen werden muß.In an advantageous embodiment of the invention, the carrier profile is already provided with an adhesive system during its manufacture. The adhesive system is brought into effect by means of an activation unit only immediately before the carrier profile is applied to the carrier surface. The reaction of the adhesive system can be triggered, for example, by supplying ultraviolet or infrared radiation or by pressure. This method has the advantage that no adhesive system has to be applied during assembly, where it is of considerable importance to save time for reasons of cost and to have as few disruptions in the course of the process as possible.
Die Erfindung ist anhand zweier Ausführungsbeispiele für Verfahren und Vorrichtung in den Figuren 1 und 2 dargestellt. Die Figuren 3 und 4 zeigen jeweils ein Trägerprofil mit einem Dichtungsprofil. Verfahren, Vorrichtung, Trägerprofile und Verbindungsbereiche werden im folgenden unter Bezugnahme auf die Figuren beschrieben. Figur 1 zeigt ein Verfahren und eine Vorrichtung, mittels deren das Klebstoffsystem unmittelbar vor dem Aufbringen des Trägerprofiles 1 auf die Trägerfläche 4 aufgetragen wird. Das Trägerprofil ist auf einem trommeiförmigen Speicher 2 aufgerollt. Das Trägerprofil wird von einer verfahrbaren Auftragseinrichtung 3 vom Speicher abgezogen und auf eine Trägerfläche 4, beispielsweise eine Türkarosserie oder einen Kofferraumverschluß geklebt. Die Bewegungen der Auftragseinrichtung werden der Kontur der Trägerfläche folgend programmiert. Die Auftragseinrichtung, ausgebildet als Industrieroboter, besteht aus Führungsrollen 5, die das Trägerprofil nach Austritt aus dem Speicher den Bewegungen der Austragseinrichtung folgend führen, einer weggesteuerten Schneideinheit 6, mittels derer das Trägerprofil nach Erreichen seiner Endlänge, beispielsweise nach Aufbringen des Trägerprofiles über den kompletten Umfang einer Tür, geschnitten wird, einem Kleberauftrag 7 mittels dessen das Klebstoffsystem auf die Trägerfläche aufgetragen wird und Andrück- und Führungsrollen 8, die das Trägerprofil umlenken und in das Klebstoffsystem drücken.The invention is illustrated in FIGS. 1 and 2 using two exemplary embodiments for the method and device. Figures 3 and 4 each show a carrier profile with a sealing profile. The method, device, support profiles and connection areas are described below with reference to the figures. FIG. 1 shows a method and a device by means of which the adhesive system is applied to the carrier surface 4 immediately before the carrier profile 1 is applied. The carrier profile is rolled up on a drum-shaped memory 2. The carrier profile is pulled from the storage device by a movable application device 3 and glued to a carrier surface 4, for example a door body or a trunk lock. The movements of the application device are programmed following the contour of the carrier surface. The application device, designed as an industrial robot, consists of guide rollers 5, which guide the carrier profile after exiting the memory following the movements of the discharge device, a path-controlled cutting unit 6, by means of which the carrier profile extends over the entire circumference after reaching its final length, for example after application of the carrier profile a door, is cut, an adhesive application 7 by means of which the adhesive system is applied to the carrier surface, and pressure and guide rollers 8 which deflect the carrier profile and press into the adhesive system.
Figur 2 zeigt ein Verfahren und eine Vorrichtung, mittels derer ein selbstklebendes Trägerprofil 9 auf eine Trägerfläche 4 aufgebracht wird. Der Unterschied zu dem in Figur 1 beschriebenen Verfahren beziehungsweise der Vorrichtung besteht darin, daß das auf den Speicher 2 aufgerollte Trägerprofil 9 bereits bei dessen Herstellung mit einem Klebstoffsystem versehen wurde. Die Auftragseinrichtung 3 beinhaltet ebenfalls Führungsrollen 5, eine weggesteuerte Schneideeinheit 6 sowie Andrück- und Führungsrollen 8. Anstatt eines Kleberauftrages ist diese Auftragseinrichtung jedoch mit einer Aktivierungseinheit 10 ausgestattet. Diese setzt die Reaktion des Klebstoffsystems an der der Trägerfläche zugewandten Seite desTrägerprofils in Gang, indem sie beispielsweise Ultraviolett- oder Infrarotstrahlung oder Druck zuführt, bevor das Trägerprofil von den Andrück- und Führungsrollen auf die Trägerfläche 4 gedrückt wird.FIG. 2 shows a method and a device by means of which a self-adhesive carrier profile 9 is applied to a carrier surface 4. The difference from the method or the device described in FIG. 1 is that the carrier profile 9 rolled onto the store 2 was already provided with an adhesive system during its manufacture. The application device 3 also contains guide rollers 5, a path-controlled cutting unit 6 and pressure and guide rollers 8. Instead of an adhesive application, however, this application device is equipped with an activation unit 10. This initiates the reaction of the adhesive system on the side of the carrier profile facing the carrier surface, for example by supplying ultraviolet or infrared radiation or pressure, before the carrier profile is pressed onto the carrier surface 4 by the pressure and guide rollers.
Figur 3 zeigt ein selbstklebendes Trägerprofil 9 mit aufgestecktem Dichtungsprofil 11 , das besonders vorteilhaft nach dem in Figur 2 dargestellten Verfahren, bzw. mit der in Figur 2 dargestellten Vorrichtung auf eine Trägerfläche 4 aufgebracht werden kann. Die geometrische Form des Trägerprofils wurde gewählt, um das Dichtungsprofil einfach auf das Trägerprofil aufstecken und wieder von diesem lösen zu können. An der der Trägerfläche zugewandten Seite ist in das Trägerprofil eine rinnenförmige Nut eingearbeitet, in die schon bei der Herstellung das Klebstoffsystem 12 aufgetragen wurde. Die Figur 4 zeigt ein Trägerprofil 1 mit einem Dichtungsprofil 11 , das sich in einen Verbindungsbereich 13 und einen Dichtbereich 14 aufteilt. In diesem Beispiel ist der Dichtbereich schlauchförmig bestehend aus Weichgummi ausgeführt; in anderen Anwendungsfällen der Erfindung kann er aber auch als Lippendichtung oder in einer anderen, dem Anwendungsfall angepaßten Form ausgebildet sein. In der schlauchförmigen Ausführung kann der Durchmesser des Dichtbereiches in Abhängigkeit von der Größe des abzudichtenden Spaltes gewählt werden. Der Dichtbereich beansprucht im gewählten Anwendungsbeispiel gegenüber dem mit ihm verbundenen, beispielsweise verklebten, Verbindungsbereich einen weitaus größeren Raum, damit der abzudichtende Raum bestmöglich ausgefüllt wird.FIG. 3 shows a self-adhesive carrier profile 9 with attached sealing profile 11, which can be applied to a carrier surface 4 particularly advantageously by the method shown in FIG. 2 or with the device shown in FIG. The geometrical shape of the carrier profile was chosen in order to be able to simply plug the sealing profile onto the carrier profile and to detach it again. On the side facing the carrier surface, a channel-shaped groove is worked into the carrier profile, into which the adhesive system 12 was already applied during manufacture. FIG. 4 shows a carrier profile 1 with a sealing profile 11, which is divided into a connecting area 13 and a sealing area 14. In this example, the sealing area is made of a soft rubber tube; in other applications of the invention, however, it can also be designed as a lip seal or in another shape adapted to the application. In the tubular design, the diameter of the sealing area can be selected depending on the size of the gap to be sealed. In the selected application example, the sealing area takes up a much larger space than the connection area connected, for example glued, so that the space to be sealed is filled as best as possible.
Daher ist auch in dem Anwendungsbeispiel der Dichtbereich aus Weichgummi ausgebildet, während der Verbindungsbereich des Dichtungsprofils und das Trägerprofil aus einem härterem Werkstoff bestehen, der einen guten Formschluß zwischen Verbindungsbereich und Trägerprofil und damit eine hohe Abzugskraft gewährleistet. Dabei ist der Werkstoff von Verbindungsbereich und Trägerprofil aber so zu wählen, daß beide Bestandteile flexibel dem Verlauf der Automobilkarosserie auch in Eckbereichen folgen können. Desweiteren muß der Werkstoff, aus dem das Trägerprofil besteht, klebefreundlich und in der Reaktion mit dem Klebstoffsystem beständig sein. Das Trägerprofil kann bereits im Herstellerwerk mit einem Klebstoffsystem 12 versehen werden, also selbstklebend sein, oder das Klebstoffsystem kann erst vor Aufbringen des Trägerprofils auf die Trägerfläche aufgetragen werden.Therefore, in the application example, the sealing area is made of soft rubber, while the connection area of the sealing profile and the support profile consist of a harder material, which ensures a good positive fit between the connection area and the support profile and thus a high pull-off force. However, the material of the connection area and support profile should be chosen so that both components can flexibly follow the course of the automobile body even in corner areas. Furthermore, the material from which the carrier profile is made must be adhesive-friendly and resistant to the reaction with the adhesive system. The carrier profile can already be provided with an adhesive system 12 in the manufacturing plant, that is to say be self-adhesive, or the adhesive system can only be applied to the carrier surface before the carrier profile is applied.
Das Trägerprofil 1 ist mit einem langen, geradlinigen Schenkel 15 ausgebildet, der im Bereich der Klebefläche in etwa parallel zur Trägerfläche 4 der Automobilkarosserie verläuft. Die lange, geradlinige Form des Schenkels wurde in Abhängigkeit von der Breite der Trägerfläche gewählt, um dem Klebstoffsystem 12 eine möglichst große Fläche zur Verfügung zu stellen und damit eine möglichst hohe Abzugskraft des Trägerprofils 1 auf der Trägerfläche 4 zu erreichen.The carrier profile 1 is formed with a long, straight leg 15, which runs approximately parallel to the carrier surface 4 of the automobile body in the region of the adhesive surface. The long, rectilinear shape of the leg was chosen as a function of the width of the carrier surface in order to provide the adhesive system 12 with the largest possible surface and thus to achieve the highest possible pull-off force of the carrier profile 1 on the carrier surface 4.
Weiterhin ist das Trägerprofil 1 mit einem Haltesteg 16 ausgebildet, der senkrecht zum Schenkel 15 in Richtung Dichtungsprofil 11 zeigt. Der Haltesteg 16 endet in einem trapezförmigen Aufsteckflansch 17.Furthermore, the carrier profile 1 is formed with a holding web 16 which points perpendicular to the leg 15 in the direction of the sealing profile 11. The retaining web 16 ends in a trapezoidal push-on flange 17.
Der Verbindungsbereich 13 des Dichtungsprofils 11 wird bei der Montage auf den trapezförmigen Aufsteckflansch 17 des Trägerprofils 1 aufgesteckt und bildet wegen seiner C- förmigen Form mit dem trapezförmigen Aufsteckflansch 17 eine formschlüssige Verbindung, die im Zusammenspiel mit einem geeignet harten, aber flexiblen Werkstoff, wie beispielsweise Hartgummi, eine hohe Abzugskraft zwischen Verbindungsbereich 13 und damit Dichtungsprofil 11 und dem Trägerprofil 1 gewährleistet.The connection area 13 of the sealing profile 11 is attached to the trapezoidal push-on flange 17 of the carrier profile 1 during assembly and forms a positive fit with the trapezoidal push-on flange 17 because of its C-shaped shape Connection which, in interaction with a suitably hard but flexible material, such as hard rubber, ensures a high pull-off force between the connection area 13 and thus the sealing profile 11 and the carrier profile 1.
In vorteilhafter Ausbildung der Erfindung ist auf der dem Haltesteg 16 gegenüberlegenden Seite der Schenkel 15 des Trägerprofils 1 mit einer Lippe 18 ausgebildet, die zur Trägerfläche 4 der Automobilkarosserie zeigt und die das Klebstoffsystem 12 zur Fahrzeuginnenseite 19 hin optisch abdeckt. In an advantageous embodiment of the invention, on the side opposite the retaining web 16, the leg 15 of the carrier profile 1 is formed with a lip 18 which faces the carrier surface 4 of the automobile body and which optically covers the adhesive system 12 towards the vehicle interior 19.
