Description

Die Erfindung betrifft einen Klebebandapplikator mit einer Aufnahme für eine Klebebandrolle und wenigstens einem Griff und einem positionsfest gegenüber dem Griff angeordneten Applikatorkopf.The invention relates to an adhesive tape applicator with a holder for a roll of adhesive tape and at least one handle and an applicator head arranged in a fixed position relative to the handle.

Klebebandapplikatoren sind im Stand der Technik natürlich grundsätzlich bekannt.Adhesive tape applicators are of course known in principle in the prior art.

Aus der DE 20 2007 011 400 U1 ist ein Klebebandhandabroller in kompakter Bauart bekannt. Der dort offenbarte Klebebandhandabroller weist ein klappbares Gehäuse mit zwei im zusammengeklappten Zustand eine Klebebandrolle bevorratende Gehäusehalbschalen auf. Eine Achse zum Aufstecken der Klebebandrolle wird durch zwei ineinander steckbare Achsstützen ausgebildet, die innenseitig an jeweils einer der beiden Gehäusehalbschalen angeordnet sind. Problematisch an dem Klebebandhandabroller ist, dass ein geführtes Aufkleben eines Maskierungsbandes entlang einer Kante in einem bestimmten Abstand nur schwer möglich ist.From the DE 20 2007 011 400 U1 a hand tape dispenser in a compact design is known. The manual adhesive tape dispenser disclosed there has a foldable housing with two housing half-shells storing a roll of adhesive tape when folded together. An axle for attaching the roll of adhesive tape is formed by two axle supports that can be plugged into one another and are arranged on the inside of one of the two half-shells of the housing. The problem with the hand tape dispenser is that guided sticking of a masking tape along an edge at a specific distance is only possible with difficulty.

In der DE 10 2005 034 007 A1 ist ein Handgerät zum Abrollen eines Klebebandes offenbart. Das Klebeband besteht aus einem einseitig mit einer klebenden Schicht ausgerüsteten Träger, dessen Klebmasse durch einen Trennmaterialstreifen abgedeckt ist. Der Klebebandhandabroller gestattet es, den Trennmaterialstreifen während des Auftragsvorgangs automatisch von der klebenden Schicht des Trägers zu lösen. Auch an diesem Klebebandhandabroller ist nachteilig, dass zum einen ein geführtes Auftragen des Klebebandes entlang einer Kante nur schwer möglich ist und zum anderen ein in Auftragsrichtung gerichteter Griff den Auftrag in Auftragsrichtung behindert.In the DE 10 2005 034 007 A1 discloses a hand-held device for unrolling an adhesive tape. The adhesive tape consists of a backing which has an adhesive layer on one side and whose adhesive mass is covered by a strip of release material. The hand tape dispenser allows the strip of release material to be automatically detached from the adhesive layer of the carrier during the application process. This hand tape dispenser also has the disadvantage that on the one hand it is difficult to apply the tape in a guided manner along an edge and on the other hand a handle directed in the direction of application impedes the application in the direction of application.

Aus der DE 20 2012 004 079 U1 ist ein Klebebandhandabroller zum Aufbringen eines Klebeband in einer Auftragsrichtung auf eine verunreinigte Oberfläche bekannt. Dabei ist in Auftragsrichtung vor einer Andrückwalze eine Reinigungseinrichtung für Oberflächenreinigungen vorgesehen. Als nächstliegender Stand der Technik wird der in der Dokument DE 20 2016 008252 U1 offenbarte Klebebandapplikator angesehen.From the DE 20 2012 004 079 U1 a hand tape dispenser for applying an adhesive tape in one application direction to a contaminated surface is known. A cleaning device for surface cleaning is provided in the direction of application in front of a pressure roller. The closest prior art is that in document DE 20 2016 008252 U1 disclosed adhesive tape applicator.

Problematisch an den bekannten Applikatoren ist, dass diese nicht geeignet sind, ein Klebeband innen auf eine Innenseite eines Spaltes aufzukleben. Derartige Spalte entstehen beispielsweise beim Kraftfahrzeugbau zwischen einem Dachholm und einer Tür.A problem with the known applicators is that they are not suitable for sticking an adhesive tape on the inside of a gap. Such gaps arise, for example, in motor vehicle construction between a roof rail and a door.

Während der Fahrzeugfertigung sind die Türen noch nicht mit einer Innenverkleidung und auch noch nicht mit Abdichtungen versehen, so dass sich ein Spalt von einigen Millimetern Breite zwischen der Tür und einem Dach ausbildet. So bildet sich entlang der Vordertür zwischen der A- und B-Säule und entlang der Hintertür zwischen der B- und C-Säule jeweils entlang des gesamten Dachholms ein Spalt aus.During the production of the vehicle, the doors are not yet fitted with an interior paneling and seals, so that there is a gap of a few millimeters forms between the door and a roof. A gap is formed along the front door between the A and B pillars and along the rear door between the B and C pillars along the entire roof pillar.

Während der Fahrzeugfertigung sind die Türen eingehängt und geschlossen. Bei einer in zunehmender Weise beliebten Zweifachlackierung des Fahrzeugs werden zunächst wird die gesamte Karosserie in einer ersten Farbe lackiert. Dann muss auf die erste Farbe ein ablösbarer Klebestreifen aufgebracht werden, um eine definierte Lackkante zwischen der ersten und einer zweiten Lackierung zu gewährleisten. Der Klebebandstreifen wird entlang des Türspaltes innen auf den Dachholm aufgeklebt. Nachteiligerweise weist der Dachholm zwischen der Innenseite und der Außenseite einen über die Längsausdehnung veränderlichen Winkel auf, der etwa bei 90° liegt, aber durchaus zwischen 45° bis 145° variieren kann. Bekannte Klebebandapplikatoren ermöglichen keine stabile manuelle Führung entlang des Spaltes.The doors are hinged and closed during vehicle manufacture. In an increasingly popular two-tone painting of the vehicle, the entire body is first painted in a first color. A detachable adhesive strip must then be applied to the first color in order to ensure a defined paint edge between the first and a second paint finish. The strip of adhesive tape is glued to the inside of the roof rail along the door gap. Disadvantageously, the roof rail has an angle between the inside and the outside that can change over the longitudinal extent, which is around 90°, but can certainly vary between 45° and 145°. Known adhesive tape applicators do not allow stable manual guidance along the gap.

Aufgabe der Erfindung ist es daher, einen eingangs genannten Klebebandapplikator zur Verfügung zu stellen, der es ermöglicht, ein Klebeband auf einer Innenseite eines Spaltes einzukleben, auch wenn sich die äußere Anlagefläche des Spaltes über die Längsausdehnung verändert.The object of the invention is therefore to provide an adhesive tape applicator mentioned at the outset which makes it possible to glue an adhesive tape to the inside of a gap, even if the outer contact surface of the gap changes over the longitudinal extent.

Die Aufgabe wird durch einen eingangs genannten Klebebandabroller mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved by an adhesive tape dispenser mentioned at the outset having the features of claim 1 .

Die Erfindung macht von der Idee Gebrauch, einen Klebebandapplikator mit einem Applikatorkopf zur Verfügung zu stellen, an dem eine Umlenkkanteneinheit beweglich gegenüber dem Applikatorkopf angeordnet ist. Die Umlenkkanteneinheit ist in einer Längsrichtung kurz, d. h. 5 bis 10 cm oder noch kürzer, ausgebildet, und sie weist eine Höhe von weniger als 2 cm, vorzugsweise weniger als 1 cm, vorzugsweise weniger als 0,5 cm auf, so dass die Umlenkkanteneinheit in den Spalt eingeführt werden kann.The invention makes use of the idea of providing an adhesive tape applicator with an applicator head on which a deflection edge unit is arranged so that it can move relative to the applicator head. The turning edge unit is short in a longitudinal direction, i. H. 5 to 10 cm or even shorter, and has a height of less than 2 cm, preferably less than 1 cm, preferably less than 0.5 cm, so that the deflection edge unit can be inserted into the gap.

Die gegenüber dem Applikatorkopf bewegliche Umlenkkanteneinheit ist vorzugsweise mit einer Feder vorgespannt. Dabei ist ein Winkel einer Neutralstellung vorzugsweise geringer als ein kleinster Winkel des Dachholms zwischen Anlageseite und Applikationsseite, so dass eine Applikationsseite der Umlenkkanteneinheit immer unter Druck gegen eine Applikationsseite des Dachholms anliegt.The deflection edge unit that is movable relative to the applicator head is preferably preloaded with a spring. In this case, an angle of a neutral position is preferably smaller than a smallest angle of the roof rail between the contact side and the application side, so that an application side of the deflection edge unit always bears against an application side of the roof rail under pressure.

Die Applikationsseite des Dachholms ist die Seite des Spaltes, auf die das Klebeband aufgebracht wird.The application side of the roof rail is the side of the gap where the tape is applied.

In einer bevorzugten Ausführungsform der Erfindung ist die Umlenkkanteneinheit um eine Längsachse gegenüber dem Applikatorkopf drehbar angeordnet, und die Umlenkkanteneinheit ist mittels einer Feder mit dem Applikatorkopf gekoppelt, die die Umlenkkanteneinheit in eine Neutralstellung gegenüber dem Applikatorkopf drückt. Die Neutralstellung ist eine Winkelstellung, die kleiner ist als der kleinste Außenwinkel zwischen seitlicher Anlageseite und Applikationsseite des zu beklebenden Profils, insbesondere Dachholms, eines Kraftfahrzeugs.In a preferred embodiment of the invention, the deflection edge unit is rotatable about a longitudinal axis relative to the applicator head, and the deflection edge unit is coupled to the applicator head by means of a spring that presses the deflection edge unit into a neutral position relative to the applicator head. The neutral position is an angular position that is smaller than the smallest outer angle between the lateral contact side and the application side of the profile to be bonded, in particular the roof rail, of a motor vehicle.

Bei der Feder kann es sich vorzugsweise um eine Schenkelfeder handeln, die um eine Längsachse gefädelt ist und mit einem Schenkel an der Umlenkkanteneinheit und mit einem anderen Schenkel um den Applikatorkopf anliegt und sie in der Neutralstellung hält.The spring can preferably be a leg spring which is threaded around a longitudinal axis and rests with one leg on the deflection edge unit and with another leg around the applicator head and holds it in the neutral position.

Vorzugsweise weist der Applikatorkopf wenigstens eine quer zur Applikationsrichtung verlaufende Quernut für das Klebeband und eine in Applikationsrichtung auf einer Applikationsseite der Umlenkkanteneinheit angeordnete Längsnut auf. Die Quernut ist dafür bestimmt, das Klebeband von einer Griffseite des Applikatorkopfes unter dem Applikator entlang der Quernut auf die Applikationsseite des Applikatorkopfes zu führen. Die Quernut ist dabei vorzugsweise vollständig, zumindest zum Teil entlang der Umlenkkanteneinheit geführt. Die Quernut endet in einer schräg verlaufenden Umlenkkante, um die das Klebeband herumgeführt ist und dann weiter durch die Längsnut entlang der Applikationsseite geführt ist. Die Umlenkkante kann auch als Nut ausgebildet sen.The applicator head preferably has at least one transverse groove for the adhesive tape running transversely to the application direction and a longitudinal groove arranged in the application direction on an application side of the deflection edge unit. The transverse groove is intended to guide the adhesive tape from a handle side of the applicator head under the applicator along the transverse groove to the application side of the applicator head. The transverse groove is preferably completely, at least partially, guided along the deflection edge unit. The transverse groove ends in an inclined deflection edge around which the adhesive tape is guided and then further guided through the longitudinal groove along the application side. The deflection edge can also be designed as a groove.

Auf der Applikationsseite liegt die Klebseite des Klebebandes frei, so dass die Klebseite direkt auf die Innenseite des Dachholms geklebt werden kann.The adhesive side of the adhesive tape is exposed on the application side, so that the adhesive side can be stuck directly to the inside of the roof rail.

Vorzugsweise ist entlang der Längsnut eine Andrückhilfe vorzugsweise ein Andrückklebeband eingebracht. Bei dem Andrückklebeband kann es sich um ein Schaumstoffklebeband handeln, das in die Längsnut entlang eines Abschnitts ihrer Längsausdehnung, möglicherweise auch entlang der gesamten Längsausdehnung eingeklebt ist. Eine freie, der Nut gegenüberliegende Seite der Andrückhilfe kann mit einer zusätzlichen reibungsvermindernden Schicht versehen sein, so dass das Klebeband entlang der Schicht möglichst reibungsarm läuft und durch das Andrückklebeband gegen die Innenseite des Dachholms gedrückt wird. Es ist auch denkbar, dass ein sogenanntes Glidingtape über die gesamt Nut einschließlich der Andrückhilfe geklebt wird.A pressing aid, preferably an adhesive pressure tape, is preferably introduced along the longitudinal groove. The adhesive pressure tape can be a foam adhesive tape that is glued into the longitudinal groove along a portion of its longitudinal extent, possibly also along the entire longitudinal extent. A free side of the pressing aid opposite the groove can be provided with an additional friction-reducing layer, so that the adhesive tape runs along the layer with as little friction as possible and is pressed against the inside of the roof rail by the pressure-sensitive adhesive tape. It is also conceivable that a so-called gliding tape is stuck over the entire groove including the pressing aid.

Vorzugsweise weist eine Aufnahme einen in Applikationsrichtung ausgerichteten Dorn auf, auf den die Klebebandrolle steckbar ist, wobei das Klebeband um wenigstens eine, vorzugsweise zwei Umlenkrollen dem Applikatorkopf zuführbar ist. Es ist auch jede höhere Anzahl an Umlenkrollen denkbar.A receptacle preferably has a mandrel aligned in the direction of application, onto which the roll of adhesive tape can be pushed, the adhesive tape being able to be fed to the applicator head around at least one, preferably two, deflection rollers. Any higher number of deflection rollers is also conceivable.

Die Aufnahme ist vorzugsweise so angeordnet, dass die Klebebandrolle mit ihrem Wickelspiegel vorzugsweise quer, besonders bevorzugt senkrecht zur Applikationsrichtung angeordnet ist, so dass sich das Klebeband mit seiner Klebseite senkrecht zur Applikationsrichtung von der Klebebandrolle abrollt. Durch die Umlenkung um die vorzugsweise im 45° Winkel angeordnete Umlenkkante wird das Klebeband, nachdem es die wenigstens eine Umlenkrolle passiert hat, umgelenkt und in Applikationsrichtung ausgerichtet.The receptacle is preferably arranged in such a way that the roll of adhesive tape is arranged with its winding level preferably transversely, particularly preferably perpendicularly, to the direction of application, so that the adhesive tape rolls off the roll of adhesive tape with its adhesive side perpendicular to the direction of application. As a result of the deflection around the deflection edge, which is preferably arranged at a 45° angle, the adhesive tape is deflected and aligned in the direction of application after it has passed the at least one deflection roller.

Besonders bevorzugt ist der Applikatorkopf mit der Umlenkkanteneinheit austauschbar an einer Grundeinheit angeordnet. Die Grundeinheit umfasst den Griff und die Aufnahme für die Klebebandrolle. Der Applikatorkopf ist ein Verschleißteil, da das Klebeband um die Umlenkkante herumgeführt wird und diese im Laufe der Zeit abgenutzt wird. Darüber hinaus können sowohl das Andrückklebeband abgenutzt werden als auch die Magneten an Stärke verlieren.The applicator head with the deflection edge unit is particularly preferably arranged on a base unit so that it can be exchanged. The base unit includes the handle and the holder for the roll of tape. The applicator head is a consumable item as the tape wraps around the deflection edge and this wears down over time. In addition, the pressure tape can both wear out and the magnets can lose strength.

Günstigerweise weist die Umlenkkanteneinheit eine erste und eine zweite Umlenkkante auf, wobei die zweite zur ersten spiegelbildlich angeordnet ist. Die Umlenkkanteneinheit ist an dem Applikatorkopf angeordnet, und der Applikatorkopf kann in verschiedenen Positionen an einem Klotz der Grundeinheit befestigt werden. Die verschiedenen Positionen entsprechen den zwei verschiedenen Applikationsrichtungen, mit denen das Band von einem Benutzer durch eine manuelle Schwenkbewegung in den Spalt eingeklebt werden kann. Der Benutzer kann das Klebeband mit einer Bewegung von rechts nach links bzw. mit einer anderen Bewegung von links nach rechts in den Spalt einbringen. Je nach Applikationsrichtung wird eine der beiden Umlenkkanten verwendet. Je nach Applikationsrichtung wird der gesamte Klebebandapplikator entsprechend umgebaut.The deflection edge unit expediently has a first and a second deflection edge, the second being arranged as a mirror image of the first. The deflection edge unit is arranged on the applicator head, and the applicator head can be fixed in different positions on a block of the base unit. The different positions correspond to the two different directions of application with which the tape can be glued into the gap by a user with a manual pivoting movement. The user can insert the adhesive tape into the gap with a movement from right to left or with another movement from left to right. Depending on the application direction, one of the two deflection edges is used. Depending on the direction of application, the entire adhesive tape applicator is rebuilt accordingly.

Weiter vorzugsweise weist der Applikatorkopf eine seitliche Anlageseite auf, an der wenigstens ein Magnet angeordnet ist. An der Applikationsseite ist ebenfalls wenigstens ein Magnet angeordnet. Die Magneten halten die Anlageseite und die Applikationsseite während der Applikation jeweils ständig in Kontakt zu einem Metallprofil.More preferably, the applicator head has a lateral contact side on which at least one magnet is arranged. At least one magnet is also arranged on the application side. The magnets keep the contact side and the application side in constant contact with a metal profile during application.

In dieser Variante kann die Umlenkkanteneinheit beweglich gegenüber dem Applikatorkopf angeordnet sein, bevorzugt ist aber, wenn ist die Umlenkkanteneinheit starr ist.In this variant, the deflection edge unit can be arranged so that it can move relative to the applicator head, but it is preferred if the deflection edge unit is rigid.

Die in der Fig. 1 dargestellte Schnittansicht zeigt den erfindungsgemäßen Klebebandapplikator mit einer Aufnahme 1 für eine Klebebandrolle 2. Die Klebebandrolle 2 ist austauschbar oder nach Verbrauch ersetzbar. Ein freies Ende eines von der Klebebandrolle 2 gelösten Klebebandes 3 wird über eine erste und eine nicht dargestellte zweite Umlenkrolle 4, 6 umgelenkt und einem Applikatorkopf 7 mit einer Umlenkkanteneinheit 8 zugeführt. Die Klebebandrolle 2 weist eine innenseitig der Wickelungen auf das Klebeband aufgebrachte Klebseite auf.The one in the 1 The sectional view shown shows the adhesive tape applicator according to the invention with a receptacle 1 for an adhesive tape roll 2. The adhesive tape roll 2 can be exchanged or replaced after consumption. A free end of an adhesive tape 3 detached from the adhesive tape roll 2 is deflected via a first and a second deflection roller 4 , 6 (not shown) and fed to an applicator head 7 with a deflection edge unit 8 . The adhesive tape roll 2 has an adhesive side applied to the adhesive tape on the inside of the windings.

Der Klebebandapplikator umfasst eine Grundeinheit 9 sowie den auf der Grundeinheit 9 austauschbar angeordneten Applikatorkopf 7. Die Grundeinheit 9 umfasst die Aufnahme 1 für die Klebebandrolle 2 mit einem an ihrem freien Ende angeordneten Dorn, auf den die Klebebandrolle 2 aufsteckbar ist sowie einen Klotz 11, an dem die Aufnahme 1 positionsfest befestigt ist. An dem Klotz 11 ist dem Applikatorkopf 7 gegenüberliegend wenigstens ein Griff 12 positionsfest gegenüber dem Klotz 11 angeordnet. Der Griff 12 ist an einer Platte 13 befestigt, die wiederum an dem Klotz 11 befestigt ist. An der Aufnahme 1 sind seitlich dem Klotz 11 gegenüberliegend die beiden Umlenkrollen 4, 6 drehbar angeordnet.The adhesive tape applicator comprises a base unit 9 and the applicator head 7 arranged interchangeably on the base unit 9. The base unit 9 comprises the receptacle 1 for the roll of adhesive tape 2 with a mandrel arranged at its free end, onto which the roll of adhesive tape 2 can be attached, and a block 11 which the receptacle 1 is fastened in a fixed position. At least one handle 12 is arranged in a fixed position relative to the block 11 on the block 11 opposite the applicator head 7 . The handle 12 is attached to a plate 13 which in turn is attached to the block 11. On the receptacle 1, the two deflection rollers 4, 6 are arranged rotatably on the side of the block 11 opposite.

An der dem Griff 12 gegenüberliegenden Seite ist an dem Klotz 11 der Applikatorkopf 7 lösbar festgeschraubt. An dem Applikatorkopf 7 ist an der der Klebebandrolle 2 abgewandten Seite die Umlenkkanteneinheit 8 vorgesehen. Die Umlenkkanteneinheit 8 ist gegenüber dem Applikatorkopf 7 um einen Winkel α schwenkbar ausgebildet. Die Umlenkkanteneinheit 8 ist um eine Längsachse L schwenkbar am Applikatorkopf 7 angeordnet. Die Längsachse L verläuft in einer Applikationsrichtung A des Klebebandes 3. Die Klebebandrolle 2 weist ebenfalls eine Längsachse auf, die ebenfalls in der Applikationsrichtung A angeordnet ist.On the opposite side of the handle 12, the applicator head 7 is releasably screwed to the block 11. The deflection edge unit 8 is provided on the applicator head 7 on the side facing away from the adhesive tape roll 2 . The deflection edge unit 8 is opposite Applicator head 7 formed pivotable by an angle α. The deflection edge unit 8 is arranged on the applicator head 7 such that it can be pivoted about a longitudinal axis L. The longitudinal axis L runs in an application direction A of the adhesive tape 3. The adhesive tape roll 2 also has a longitudinal axis which is also arranged in the application direction A.

Die Umlenkkanteneinheit 8 weist eine Applikationsseite 14 auf, die in Fig. 1 oben auf der Umlenkkanteneinheit 8 angeordnet ist. Entlang der Applikationsseite 14 ist eine Längsnut 16 vorgesehen. In die Längsnut 16 ist ein in Fig. 1 nicht dargestelltes Andrückklebeband 17 eingeklebt. Bei dem Andrückklebeband 17 handelt es sich um ein Schaumstoffklebeband, das eine Breite aufweist, die einer Breite B der Längsnut 16 entspricht. Das Andrückklebeband 17 erstreckt sich entlang eines Abschnitts der Längsausdehnung der Längsnut 16 und ist in die Längsnut 16 eingeklebt. Auf eine freie, der Längsnut 16 abgewandte Außenseite des Andrückklebebands 17 kann eine reibungsvermindernde Schicht aufgebracht sein.The deflection edge unit 8 has an application side 14, which 1 is arranged on top of the deflection edge unit 8. A longitudinal groove 16 is provided along the application side 14 . In the longitudinal groove 16 is an in 1 not shown pressure tape 17 glued. The adhesive pressure tape 17 is an adhesive foam tape that has a width that corresponds to a width B of the longitudinal groove 16 . The adhesive pressure tape 17 extends along a section of the longitudinal extent of the longitudinal groove 16 and is glued into the longitudinal groove 16 . A friction-reducing layer can be applied to a free outside of the pressure-sensitive adhesive tape 17 facing away from the longitudinal groove 16 .

Das Klebeband 3 wird um eine gegenüber der Applikationsrichtung A schräge Umlenkkante 18 geführt. Fig. 2 zeigt in einer Durchsicht der Umlenkkanteneinheit 8 den detaillierten Aufbau der Umlenkkanteneinheit 8. Das in Fig. 2 nicht mehr dargestellte Klebeband 3 ist um die erste Umlenkrolle 4 und die in einer Abziehrichtung nachfolgenden zweite Umlenkrolle 6 gemäß Fig. 1 geführt. Das Klebeband 3 ist unterhalb der Umlenkkanteneinheit 8 in einer Quernut 19, die in die Umlenkkanteneinheit 8 eingelassen ist, von einer Griffseite zur Umlenkkante 18 des Applikatorkopfes 7 geführt. Die Quernut 19 verläuft senkrecht zur Applikationsrichtung A und senkrecht zur Drehachse der Umlenkkanteneinheit 8.The adhesive tape 3 is guided around a deflection edge 18 that is inclined relative to the application direction A. 2 shows the detailed structure of the deflection edge unit 8 in a review of the deflection edge unit 8. The in 2 Adhesive tape 3, no longer shown, is wrapped around the first deflection roller 4 and the second deflection roller 6, which follows in a peeling direction, according to FIG 1 guided. The adhesive tape 3 is guided below the deflection edge unit 8 in a transverse groove 19 which is embedded in the deflection edge unit 8, from a handle side to the deflection edge 18 of the applicator head 7. The transverse groove 19 runs perpendicularly to the application direction A and perpendicularly to the axis of rotation of the deflection edge unit 8.

An der Applikationsseite 14 mündet die Quernut 19 in die schräge Umlenkkante 18. Eine Klebebandführung ist um die Umlenkkante 18 herumgeführt und in der Längsnut 16 auf der Applikationsseite 14 des Applikatorkopfes 7, beziehungsweise der Umlenkkanteneinheit 8, weitergeführt. Die Längsnut 16 verläuft in Applikationsrichtung A.On the application side 14, the transverse groove 19 opens into the oblique deflection edge 18. An adhesive tape guide is guided around the deflection edge 18 and in the longitudinal groove 16 on the application side 14 of the applicator head 7, or the deflection edge unit 8, continued. The longitudinal groove 16 runs in the application direction A.

Sowohl der Applikatorkopf 7 als auch die Umlenkkanteneinheit 8 sind spiegelsymmetrisch ausgebildet und weisen dafür entsprechende Befestigungsmittel am Klotz 11 auf. Der in Fig. 2 dargestellte Klebebandapplikator ist für ein Aufbringen des Klebebandes 3 mittels einer manuellen Bewegung in Applikationsrichtung A von rechts nach links ausgebildet. Bei einer Applikationsrichtung A, die von links nach rechts verläuft, müssten die Aufnahme 1 und der Applikatorkopf 7 spiegelbildlich an dem Klotz 11 angeordnet sein.Both the applicator head 7 and the deflection edge unit 8 are of mirror-symmetrical design and have corresponding fastening means on the block 11 for this purpose. the inside 2 The adhesive tape applicator shown is designed for applying the adhesive tape 3 by means of a manual movement in the application direction A from right to left. In the case of an application direction A, which runs from left to right, the receptacle 1 and the applicator head 7 would have to be arranged on the block 11 in a mirror-inverted manner.

Fig. 3 zeigt die Ansicht des Klebebandapplikators von unten. Dabei ist das Klebeband 3 um die zweite Umlenkrolle 6 herumgeführt in die Quernut 19 hineingeführt und von dort um die schräge Umlenkkante 18 herum auf die Applikationsseite 14 der Umlenkkanteneinheit 8 geführt. 3 shows the bottom view of the tape applicator. In this case, the adhesive tape 3 is led around the second deflection roller 6 into the transverse groove 19 and from there to the oblique deflection edge 18 around on the application side 14 of the deflection edge unit 8 out.

Die erfindungsgemäße Umlenkkanteneinheit 8 ist schwenkbar gegenüber und an dem Applikatorkopf 7 ausgebildet. In den Applikatorkopf 7 ist eine Aussparung 22 mit zwei seitlichen Bohrungen 22a, 22b für eine entlang der Längsachse L verlaufende Achse 23 eingebracht. Um die Längsachse L herum ist die Umlenkkanteneinheit 8 schwenkbar angeordnet.The deflection edge unit 8 according to the invention is designed to be pivotable relative to and on the applicator head 7 . A recess 22 with two lateral bores 22a, 22b for an axis 23 running along the longitudinal axis L is introduced into the applicator head 7 . The deflection edge unit 8 is arranged to be pivotable about the longitudinal axis L.

Auf die Längsachse L ist eine Schenkelfeder 24 gesteckt, die die Umlenkkanteneinheit 8 in einer Neutralstellung gegenüber dem Applikatorkopf 7 hält. In der Neutralstellung weist die Umlenkkanteneinheit 8 einen Winkel α von etwa 20°-90°, vorzugsweise von 40° - 60° gegenüber dem Applikatorkopf 7 auf. Dabei ist der Winkel α zwischen der Applikationsseite 14 der Umlenkkanteneinheit 8 und einer seitlichen Anlageseite 26 des Applikatorkopfes 7 gemessen. Es sind natürlich auch andere Winkel α der Neutralstellung denkbar. Sowohl beim Herausklappen der Umlenkkanteneinheit 8 als auch beim Hineinklappen der Umlenkkanteneinheit 8 jeweils aus der Neutralstellung muss also eine Kraft auf die Umlenkkanteneinheit 8 ausgeübt werden.A torsion spring 24 is placed on the longitudinal axis L, which keeps the deflection edge unit 8 in a neutral position relative to the applicator head 7 . In the neutral position, the deflection edge unit 8 has an angle α of approximately 20°-90°, preferably 40°-60°, relative to the applicator head 7 . The angle α is measured between the application side 14 of the deflection edge unit 8 and a lateral contact side 26 of the applicator head 7 . Of course, other angles α of the neutral position are also conceivable. A force must therefore be exerted on the deflection edge unit 8 both when the deflection edge unit 8 is folded out and when the deflection edge unit 8 is folded in from the neutral position.

Zur Applikation des Klebebandes 3 wird die Umlenkkanteneinheit 8 manuell mit einem Daumen oder einem Finger in eine etwa senkrechte Stellung gegenüber dem Applikatorkopf 7 ausgeklappt. Dabei ist die Klebebandrolle 2 auf den Dorn der Aufnahme 1 aufgesteckt, und das Klebeband 3 ist über die Umlenkrollen 4, 6 durch die Quernut 19, um die Umlenkkante 18 herum und durch die Längsnut 16 gefädelt.To apply the adhesive tape 3 , the deflection edge unit 8 is folded out manually with a thumb or a finger into an approximately vertical position relative to the applicator head 7 . The roll of adhesive tape 2 is slipped onto the mandrel of the receptacle 1 and the adhesive tape 3 is threaded over the deflection rollers 4, 6 through the transverse groove 19, around the deflection edge 18 and through the longitudinal groove 16.

Dann wird die Umlenkkanteneinheit 8 des Klebebandapplikator in einen Applikationsspalt eingesteckt und der Klebebandapplikator von rechts nach links entlang des Applikationsspaltes gezogen. Der Applikationsspalt ist dabei beispielsweise der Spalt zwischen einem Dachholm 36 eines Kraftfahrzeuges und der geschlossenen Tür des Kraftfahrzeugs, wobei die Tür noch nicht mit einer Innenverkleidung und Dichtungen versehen ist, so dass der Spalt von einigen Millimetern Breite zwischen der Tür und dem Dachholm 36 ausgebildet wird. In einem Querschnitt weist der Dachholm 36 jedoch beispielsweise zwischen der C-Säule und B-Säule und der B-Säule und A-Säule des Kraftfahrzeugs unterschiedliche Winkel auf, denen sich der erfindungsgemäße Klebebandapplikator jedoch automatisch beim Entlangziehen anpasst, indem der Klebebandapplikator sowohl mit der seitlichen Anlageseite 26 gegen den Dachholm 36 gezogen wird als auch von unten die Umlenkkanteneinheit 8 mit ihrer Applikationsseite 14 gegen den Dachholm 36 gezogen wird.Then the deflection edge unit 8 of the adhesive tape applicator is inserted into an application gap and the adhesive tape applicator is pulled from right to left along the application gap. The application gap is, for example, the gap between a roof rail 36 of a motor vehicle and the closed door of the motor vehicle, the door not yet being provided with an inner lining and seals, so that the gap a few millimeters wide between the door and the roof rail 36 is formed . In a cross section, however, the roof rail 36 has different angles, for example between the C-pillar and B-pillar and the B-pillar and A-pillar of the motor vehicle, to which the adhesive tape applicator according to the invention adapts automatically when pulled along by connecting the adhesive tape applicator to both the lateral contact side 26 is pulled against the roof rail 36 and the deflection edge unit 8 is pulled with its application side 14 against the roof rail 36 from below.

Der in der Regel nicht rechtwinkelige, sondern variierend ausgebildete Winkel zwischen der Applikationsseite 14 und der seitlichen Anlageseite 26 wird durch die Schwenkbarkeit der Umlenkkanteneinheit 8 gegenüber dem Applikatorkopf 7 ausgeglichen.The angle between the application side 14 and the lateral contact side 26 that is not usually right-angled, but varies, is compensated for by the pivotability of the deflection edge unit 8 relative to the applicator head 7 .

In die Applikationsseite 14 wie auch in die seitliche Anlageseite 26 ist jeweils wenigstens ein Magnet eingelassen. In die Applikationsseite 14 ist ein applikationsseitiger Magnet 27 und in die seitliche Anlageseite sind ein erster und ein zweiter seitlicher anlageseitiger Magnet 28a, 28b eingelassen. Die Magnete 27, 28a, 28b ziehen die Applikationsseite 14 bzw. die seitliche Anlageseite 26 gegen das Stahlprofil eines Daches 32.At least one magnet is embedded in the application side 14 as well as in the lateral contact side 26 . An application-side magnet 27 is embedded in the application side 14 and a first and a second lateral contact-side magnet 28a, 28b are embedded in the lateral contact side. The magnets 27, 28a, 28b pull the application side 14 or the lateral contact side 26 against the steel profile of a roof 32.

Die Fig. 4 zeigt die Umlenkkanteneinheit 8 in einer Draufsicht und Fig. 5 in einer seitlichen Ansicht. Die Umlenkkanteneinheit 8 ist im Wesentlichen zweiteilig ausgebildet. Sie weist die eigentliche Umlenkkanteneinheit 8 und einen verschiebbaren Deckel 29 auf. In einen Innenraum 31 der Umlenkkanteneinheit 8 kann der eine Magnet 27 eingeklemmt, eingeklebt oder eingelegt und aus ihm auch leicht wieder herausgenommen werden. Der in den Innenraum 31 hineingelegte Magnet 27 wird durch Schließen des Deckels 29 am Herausfallen gehindert. Der Deckel 29 kann über eine im Deckel 29 vorgesehene Bohrung, durch die eine (nicht dargestellte) Schraube geführt ist, am zufälligen Öffnen gehindert werden. Die in den Fig. 4 und 5 dargestellte Umlenkkanteneinheit 8 ist in dem Applikatorkopf 7 um die Achse 23 herum drehbar gelagert.the 4 shows the deflection edge unit 8 in a plan view and figure 5 in a side view. The deflection edge unit 8 is essentially formed in two parts. It has the actual deflection edge unit 8 and a cover 29 that can be moved. One magnet 27 can be clamped, glued or inserted into an interior space 31 of the deflection edge unit 8 and can also be easily removed from it again. The magnet 27 placed in the interior 31 is prevented from falling out by closing the cover 29 . The cover 29 can be prevented from accidentally opening via a hole provided in the cover 29 through which a screw (not shown) is passed. The in the Figures 4 and 5 The deflection edge unit 8 shown is rotatably mounted in the applicator head 7 about the axis 23 .

Fig. 5 zeigt eine seitliche Ansicht der Umlenkkanteneinheit 8 in Fig. 4. Dabei ist eine T-förmige Nut 30 zu erkennen, in die der mit einer entsprechenden Feder ausgestattete Deckel 29 einschiebbar ist. Fig. 5 zeigt auch die beiden Quernuten 19, entlang denen das Klebeband geführt ist, um dann über die Umlenkkante 18 umgelenkt zu werden. figure 5 shows a side view of the deflection edge unit 8 in 4 . A T-shaped groove 30 can be seen here, into which the cover 29 equipped with a corresponding spring can be inserted. figure 5 also shows the two transverse grooves 19 along which the adhesive tape is guided in order to then be deflected over the deflection edge 18 .

Fig. 6 zeigt im unteren Bereich eine seitliche Ansicht einer Fahrzeugseite und des Daches 32 eines Kraftfahrzeuges. In dem oberen Abschnitt der Fig. 6 sind Querschnitte an verschiedenen Stellen des Dachholms 36 dargestellt, die mit einem Pfeil gekennzeichnet sind. Der erste Querschnitt ist vor der A-Säule, der zweite und dritte Querschnitt sind zwischen der A- und B-Säule und der dritte Querschnitt ist im Bereich der C-Säule des Kraftfahrzeuges angeordnet. Zu erkennen ist, dass ein Winkel α zwischen einer Innenseite 34, die zur Tür weist, und einer Außenseite 33 des Dachholms 36, die in das Dach 32 übergeht, variabel ist. Im ersten Schnitt vor der A-Säule beträgt der Winkel α zwischen der Innenseite 34 und der Außenseite 33 α > 90°, während er zwischen der A- und B-Säule bei dem Winkel α von etwa 85° - 95° variiert und im Bereich der C-Säule etwa wieder α = 95° annimmt. Da der Klebebandapplikator von außen gegen die Außenseite 33 und von unten gegen die Innenseite 34 des Dachholms 36 gedrückt wird, wird der Winkel α zwischen der Umlenkkanteneinheit 8 und dem Applikatorkopf 7 diesem Winkel zwischen der Außenseite 33 und der Innenseite 34 automatisch beim Entlangführen des Klebebandapplikators entlang des Dachholms 36 angepasst. 6 1 shows a side view of a vehicle side and the roof 32 of a motor vehicle in the lower area. In the upper section of the 6 cross-sections are shown at different points of the roof rail 36, which are marked with an arrow. The first cross section is in front of the A pillar, the second and third cross sections are between the A and B pillars and the third cross section is in the area of the C pillar of the motor vehicle. It can be seen that an angle α between an inner side 34, which faces the door, and an outer side 33 of the roof rail 36, which merges into the roof 32, is variable. In the first section in front of the A-pillar, the angle α between the inside 34 and the outside 33 is α > 90°, while between the A and B-pillars it varies at the angle α from about 85° - 95° and in the range of the C-pillar assumes α = 95° again. Since the adhesive tape applicator is pressed from the outside against the outside 33 and from below against the inside 34 of the roof rail 36 the angle α between the deflection edge unit 8 and the applicator head 7 is automatically adjusted to this angle between the outside 33 and the inside 34 when the adhesive tape applicator is guided along the roof rail 36 .
