Description

Die Erfindung betrifft ein selbstklebendes Band zum Verschließen, Abdichten und Verkleben von Fugen, insbesondere im Hausbau, und insbesondere von Fugen in Ecken und Kanten, ein sogenanntes Montageband, mit einer Trägerschicht an der Bandoberseite, einer Haftkleberbeschichtung der Trägerschicht an der Bandunterseite und mit einer abziehbaren Abdeckfolie an der Bandunterseite.The invention relates to a self-adhesive tape for closing, sealing and bonding joints, especially in house building, and in particular joints in corners and edges, a so-called assembly tape, with a carrier layer on the tape top, a pressure-sensitive adhesive coating of the carrier layer on the underside of the tape and with a peelable Cover foil on the underside of the belt.

Allgemein finden solche Klebebänder z.B. Anwendung, wenn im Hausbau verschiedene Bauelemente, wie Türen oder Fenster, in eine Wandöffnung eingesetzt werden und die dabei zwischen den Bauelementen und der entsprechenden Wandöffnung entstehende Fuge verschlossen wird, was speziell beim Einbau solcher Bauelemente in Gebäudeaußenwände erfolgen muss, um eine entsprechende Dichtwirkung zu erzielen.Generally such adhesive tapes find e.g. Application, when used in house construction various components, such as doors or windows, in a wall opening and the resulting gap between the components and the corresponding wall opening is closed, which must be done especially when installing such components in building exterior walls to achieve a corresponding sealing effect ,

Ein generelles Problem solcher selbstklebender Bänder ist, in schwer zugänglichen Bereichen bei möglichst unkomplizierter Anwendung dennoch eine gute Abdichtwirkung durch korrekte Anbringung solcher Bänder zu erzielen, um ein möglichst luft- bzw. feuchtigkeitsdichtes Verschließen der Fugen zu erreichen.A general problem of such self-adhesive tapes is to achieve a good sealing effect in the most uncomplicated application in hard to reach areas by correct attachment of such bands in order to achieve a possible air or moisture-tight closing of the joints.

Die deutsche Offenlegungsschrift DE 101 35 799 A1 derselben Anmelderin zeigt ein Montageklebeband zur verbesserten Fugenabdichtung mit einem geeigneten Montageband-Dispenser, wobei das entsprechende Montageband auf der Bandunterseite eine auf einer Trägerschicht auf einer Bandoberseite vorgesehene Klebeschicht aufweist, welche mit einer abziehbaren Deckfolie an der Bandunterseite versehen ist. Die Deckfolie weist in Längsrichtung des Bandes verlaufend einen Schlitz auf und das Band ist entlang dieses Schlitzes in Querrichtung einmal so auf sich selbst gefaltet, dass mindestens ein Teil der Deckfolie außen, d.h. an der Bandoberseite liegt. Ferner weist dieses Band mindestens einen seitlichen Längsabschnitt auf, welcher perforiert ist. Um beim Transport und der Anwendung das auf Grund der Deckfolienabdeckung relativ leicht in sich verrutschende Montageklebeband in aufgerollter Form sicher handhaben zu können, ist ein spezieller Montageband-Dispenser zur Aufnahme und Ausgabe des Montageklebebandes vorgesehen. Die einzelne Umfaltung des Montageklebebandes entlang eines Schlitzes der Deckfolie erlaubt es, dass das bekannte Montageklebeband auch in schwer zugänglichen Bereichen effektiv verklebbar ist. Durch die einfache Umfaltung entlang eines Schlitzes ist zwar eine zuverlässige Verarbeitbarkeit gegeben, jedoch muss bei der Verarbeitung immer zunächst entlang des Schlitzes der Faltungskante die Abdeckfolie vor der eigentlichen Anbringung des genannten Montageklebebandes entfernt werden. Auch kann es in bestimmten Anwendungsfällen, insbesondere bei sehr beengten räumlichen Verhältnissen, wünschenswert sein, die Handhabbarkeit noch weiter zu optimieren.The German patent application DE 101 35 799 A1 of the same Applicant shows a mounting tape for improved joint sealing with a suitable assembly tape dispenser, wherein the corresponding mounting tape on the underside of the band has provided on a support layer on a tape top adhesive layer, which provided with a peelable cover sheet on the underside of the belt is. The cover sheet has a slot running in the longitudinal direction of the tape and the tape is once along this slot in the transverse direction folded on itself so that at least part of the cover sheet is outside, ie at the top of the tape. Furthermore, this band has at least one lateral longitudinal section which is perforated. In order to be able to safely handle the assembly adhesive tape in rolled-up form, which is relatively easy to slip into itself during transport and application due to the cover film cover, a special assembly tape dispenser is provided for receiving and outputting the assembly adhesive tape. The individual refolding of the assembly adhesive tape along a slot of the cover film allows the known assembly adhesive tape can be effectively bonded even in hard to reach areas. The simple refolding along a slot while a reliable workability is given, however, must always be removed during the processing initially along the slot of the folding edge, the cover before the actual attachment of said mounting tape. It may also be desirable in certain applications, especially in very confined spatial conditions, to further optimize the handling.

Gemäß der Erfindung ist zumindest ein erster Faltabschnitt des Bandes in Querrichtung entlang einer in Längsrichtung des Bandes verlaufenden ersten Faltungskante umgefaltet, wobei diese erste Faltungskante an einer anderen Stelle als der erste Schlitz verläuft.The self-adhesive tape according to the invention for closing, sealing and bonding joints, especially in house building, and in particular of joints in Corners and edges, which are particularly difficult to reach, has a carrier layer on the top side of the tape, a pressure-sensitive adhesive coating of the carrier layer on the underside of the tape, and a peelable cover film on the underside of the tape, wherein the cover film has at least one first slot. According to the invention, at least a first folding portion of the band is folded transversely along a first folding edge running in the longitudinal direction of the band, this first folding edge extending at a location other than the first slot.

Durch die erfindungsgemäße Kombination einer Umfaltung des Bandes entlang einer ersten Faltungskante und einem ersten Schlitz, welcher an einer anderen Stelle als die erste Faltungskante verläuft, ergibt sich unter bestimmten Bedingungen eine weiter erbesserte Verarbeitbarkeit des Bandes. Durch die Vorfaltung kann einerseits die Anbringung in Ecken und an Kanten vereinfacht werden, während die Schlitzung die Möglichkeit bietet, abschnittsweise die Abdeckfolie von der Haftkleberbeschichtung zu entfernen und das Band an einem solchen Klebeabschnitt beispielsweise mit einem abzudichtenden Fensterrahmen zu verkleben. Dadurch, dass Schlitzung und Faltungskante nicht zusammenfallen, ergibt sich der Vorteil, dass nur der festzuklebende Bereich des erfindungsgemäßen Bandes von einem entsprechenden Abschnitt der Abdeckfolie entfernt werden muss, während die Faltungskante beabstandet von dem Verklebeabschnitt verläuft. Dies bietet Vorteile besonders dort, wo Einbauten über Eck vorzunehmen sind und dieses Eck an einer anderen Stelle verläuft als der Bereich des Bauelements, an dem das Band verklebt werden soll. Unter solchen speziellen geometrischen Bedingungen bietet das entsprechende erfindungsgemäß gestaltete Selbstklebeband somit den Vorteil einer weiter verbesserten Verarbeitbarkeit, wodurch auch die Sicherheit der Anbringung und somit die Dichtwirkung unter allen Umständen gewährleistet ist.The inventive combination of a folding of the tape along a first folding edge and a first slot, which runs at a location other than the first folding edge, results under certain conditions a further improved processability of the tape. By pre-folding on the one hand, the attachment in corners and edges can be simplified, while the slit offers the opportunity to remove sections of the cover from the pressure-sensitive adhesive coating and glue the tape to such an adhesive portion, for example, with a sealed window frame. The fact that the slit and the folding edge do not coincide results in the advantage that only the area of the strip according to the invention to be adhered must be removed from a corresponding section of the cover foil, while the folding edge runs at a distance from the gluing section. This offers advantages especially where installations are to be made over corner and this corner at a different location than the area of the device to which the tape is to be glued. Under such special geometric conditions, the corresponding self-adhesive tape designed according to the invention thus offers the advantage of further improved processability, whereby the safety of the attachment and thus the sealing effect is ensured under all circumstances.

Ein solches erfindungsgemäßes Band kann beispielsweise im Trockenausbau und/oder im Massivbau Verwendung finden. Insbesondere an räumlich schwer zugänglichen Stellen, wie 90°-Ecken, z.B. zwischen zwei aufeinander stoßenden Trockenausbauwänden, oder auch im Fensterbereich, wo das erfindungsgemäße Band möglichst genau an dem Fensterrahmen verklebbar ist, wird so das Risiko vermieden, dass beim späteren Verputzungsvorgang das Band durch einen Schlag der Verputzerkelle durchtrennt wird und somit dessen Luftdichtheit verloren geht. Die Vorfaltung erspart dem Anwender dabei viel Zeit, insbesondere wenn größere Fensterflächen mit mehreren eingesetzten Fensterrahmen bei einem Hausneubau in die Außenwände einzusetzen sind. Ansonsten müssten die entsprechende Faltung von Hand erfolgen, dies ist erfindungsgemäß nicht erforderlich. Setzt man das erfindungsgemäße Klebeband im Holzbau ein, so reicht es dort, dass aufgrund der auftretenden schmaleren Fugenbreite zwischen aneinander grenzenden Bauelementen, nur einzelne Abschnitte bzw. Randabschnitte des Dichtbandes zu verkleben, so dass durch entsprechende erfindungsgemäße Anordnung von einer geeigneten Schlitzung bzw. von geeigneten Schlitzungen eine sehr präzise und rasche Verarbeitbarkeit des erfindungsgemäßen Bandes ermöglicht wird.Such a band according to the invention can be used, for example, in dry construction and / or in solid construction. Especially in spatially difficult accessible areas, such as 90 ° corners, eg between two abutting drywall walls, or in the window area, where the tape according to the invention as close as possible glued to the window frame, so the risk is avoided, that in the subsequent Verputzungsvorgang the tape by a blow the plastering trowel is severed and thus its airtightness is lost. The pre-folding saves the user a lot of time, especially when larger window areas with several inserted window frames are to be used in a new building in the outer walls. Otherwise, the corresponding folding would have to be done by hand, this is not required according to the invention. If the adhesive tape according to the invention is used in timber construction, then it suffices there to adhere only individual sections or edge sections of the sealing tape due to the narrower joint width occurring between adjoining components, so that by appropriate arrangement according to the invention a suitable slit or of suitable slit Slotting a very precise and rapid processability of the tape of the invention is made possible.

Bevorzugt ist eine Ausführungsform der Erfindung, bei welcher das Band einen zweiten Faltungsabschnitt aufweist, welcher in Querrichtung entlang einer in Längsrichtung des Bandes verlaufenden zweiten Faltungskante umgefaltet ist. Durch diesen zweiten Faltungsabschnitt ist es beispielsweise möglich, im Rahmen einer Anwendung zwischen mehreren U-Profilen ein entsprechend gestaltetes Selbstklebeband auf einfache Art und Weise zu verwenden.An embodiment of the invention is preferred in which the band has a second folding section, which is folded over in the transverse direction along a second folding edge extending in the longitudinal direction of the band. By means of this second folding section, it is possible, for example, to use a suitably designed self-adhesive tape in a simple manner within the scope of an application between a plurality of U-profiles.

Bevorzugt kann die Abdeckfolie des erfindungsgemäßen Bandes zumindest einen zweiten Schlitz in Längsrichtung des Bandes aufweisen. Somit ergibt sich zumindest eine weitere Möglichkeit, die Abdeckfolie entsprechend abschnittsweise von der Bandunterseite bzw. von der Haftkleberbeschichtung an der Bandunterseite zu entfernen. Es bietet sich somit die Möglichkeit, zwei Haftabschnitte vorzusehen, wohingegen ein Abschnitt des vorteilhaft gestalteten erfindungsgemäßen Bandes mit der Abdeckfolie abgedeckt bleibt, beispielsweise ein Mittelbereich, welcher zwischen dem Bauelement und der eigentlichen Wand liegt.The cover film of the tape according to the invention may preferably have at least one second slot in the longitudinal direction of the tape. This results in at least one further possibility of removing the cover film correspondingly in sections from the underside of the tape or from the pressure-sensitive adhesive coating on the underside of the tape. It thus offers the possibility to provide two adhesive portions, whereas a portion of the advantageously designed tape according to the invention remains covered with the cover, for example, a central region which lies between the component and the actual wall.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung fällt die zweite Faltungskante mit dem zweiten Schlitz der Abdeckfolie zusammen. Damit ergibt sich die Möglichkeit, vom zweiten Faltabschnitt die Abdeckfolie der Haftkleberbeschichtung abzuziehen und das entsprechende Montageband im Bereich des zweiten Faltabschnitts zu verkleben.According to a further preferred embodiment of the invention, the second folding edge coincides with the second slot of the cover film. This results in the possibility of deducting the covering film of the pressure-sensitive adhesive coating from the second folding section and bonding the corresponding assembly line in the region of the second folding section.

Gemäß einer weiteren bevorzugten Ausführungsform ist es jedoch auch möglich, dass die zweite Faltungskante nicht mit dem ersten Schlitz und/oder dem zweiten Schlitz der Abdeckfolie zusammenfällt. Somit bietet sich eine flexible Gestaltungsmöglichkeit, bei welcher nicht zwingend die Abdeckfolie entlang des ersten Schlitzes und/oder entlang des zweiten Schlitzes von dem gesamten zweiten Faltungsabschnitt entfernt werden muss. Eine individuelle Anpassung an unterschiedliche Gegebenheiten, wobei insbesondere auch nur ein Teil des zweiten Faltungsabschnitts durch eine entsprechend angebrachte Schlitzung erlaubt, dort die Abdeckfolie abzuziehen, ist somit möglich.According to a further preferred embodiment, however, it is also possible that the second folding edge does not coincide with the first slot and / or the second slot of the cover film. Thus, there is a flexible design possibility, in which not necessarily the cover film along the first slot and / or along the second slot must be removed from the entire second folding section. An individual adaptation to different conditions, wherein in particular only a part of the second folding section by a correspondingly mounted slit allows to subtract the cover there, is thus possible.

Entsprechendes gilt für die Ausführungsform der Erfindung, bei welcher bevorzugt die erste Faltungskante nicht mit dem zweiten Schlitz der Abdeckfolie zusammenfällt.The same applies to the embodiment of the invention, in which preferably the first folding edge does not coincide with the second slot of the cover.

Nicht zusammenfallende Faltungskante(n) und Schlitz(e) können bevorzugt einen Abstand voneinander zum jeweiligen Nachbarn im Bereich von 1 mm bis 25 cm aufweisen.Non-coincident folding edge (s) and slot (s) may preferably have a distance from each other in the range of 1 mm to 25 cm from each other.

Gemäß einer bevorzugten Ausführungsform der Erfindung steht ein Randabschnitt der Abdeckfolie über die erste Faltungskante und/oder die zweite Faltungskante vor. Auf diese Weise ergibt/ergeben sich ein bzw. zwei Angreifabschnitt(e), welche(r) die Entfernung der Abdeckfolie auf einfache Art und Weise durch Angreifen am genannten Randabschnitt ermöglicht/ermöglichen. Dies erleichtert die Handhabbarkeit der erfindungsgemäßen Selbstklebefolie noch zusätzlich. Der Abschnitt/die Abschnitte kann/können bevorzugt eine Breite im Bereich von 1 mm bis 1cm aufweisen.According to a preferred embodiment of the invention, an edge section of the cover film protrudes beyond the first folding edge and / or the second folding edge. In this way, one or two engaging portions (e) result, which allow the removal of the cover sheet in a simple manner by engaging with said edge portion. This further facilitates the handling of the self-adhesive film according to the invention. The section (s) may preferably have a width in the range of 1 mm to 1 cm.

Je nach individueller Anwendungssituation können unterschiedliche Anordnungen der Faltabschnitte für eine Verarbeitbarkeit besonders vorteilhaft sein.Depending on the individual application situation, different arrangements of the folding sections can be particularly advantageous for processability.

Gemäß einer bevorzugten Ausführungsform der Erfindung können der erste Faltabschnitt und der zweite Faltabschnitt jeweils gegenüber liegende Randabschnitte des erfindungsgemäßen Bandes sein, es ist jedoch auch möglich, dass gemäß einer weiteren bevorzugten Ausführungsform der Erfindung der erste Faltabschnitt und der zweite Faltabschnitt in Querrichtung des Bandes gesehen aneinander angrenzen. Auch können der erste Faltabschnitt und der zweite Faltabschnitt gemäß einer weiteren bevorzugten Ausführungsform im umgefalteten Zustand des Bandes zumindest teilweise aufeinander liegen.According to a preferred embodiment of the invention, the first folding portion and the second folding portion may each be opposite edge portions of the tape according to the invention, but it is also possible that according to another preferred embodiment of the invention, the first folding portion and the second folding portion seen in the transverse direction of the tape together adjoin. Also, the first folding portion and the second folding portion according to a further preferred embodiment in the folded state of the band are at least partially on each other.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung kann im Bereich des ersten Faltabschnitts und/oder im Bereich des zweiten Faltabschnitts Bandunterseite auf Bandunterseite aufliegen, es ist jedoch gemäß einer weiteren bevorzugten Ausführungsform auch möglich, dass im Bereich des ersten Faltabschnitts und/oder im Bereich des zweiten Faltabschnitts Bandoberseite auf Bandoberseite aufeinander liegt.According to a further preferred embodiment of the invention, in the region of the first folding section and / or in the region of the second folding section, lower side of the belt rest on the underside of the belt, however, according to a further preferred embodiment, it is also possible that in the region of the first folding section and / or in the region of the second Faltabschnitts tape top on top of the tape lies on each other.

Besonders bevorzugt ist eine Ausführungsform der Erfindung, bei welcher mindestens ein Teil der Haftkleberbeschichtung nicht mit der Abdeckfolie abgedeckt ist. Entlang des mit der Abdeckfolie nicht abgedeckten Teils der Haftkleberbeschichtung des erfindungsgemäßen Bandes muss dort die Abdeckfolie während des Verlegevorgangs nicht erst mühsam entfernt werden, wodurch sich eine raschere Verarbeitbarkeit des erfindungsgemäßen Bandes ergibt. Auch wird dadurch verhindert, dass eventuell durch das sonst erforderliche Abziehen der Folie Verwerfungen und Falten im angeklebten Band auftreten. Auch erfordert ein solches erfindungsgemäß gestaltetes Band keinen zusätzlichen Montageband-Dispenser zur Aufnahme und Ausgabe des Bandes, da sich im gefalteten bzw. aufgerollten Zustand das erfindungsgemäße Band gemäß dieser bevorzugten Ausführungsform aufgrund seiner teilweise von der Abdeckfolie frei bleibenden Haftkleberbeschichtung nicht in sich verschieben wird. Das Band ist somit besonders einfach und zuverlässig verwendbar. Auch kann das Band somit ohne besonderen Verpackungsaufwand und Schutzaufwand durch den Verarbeiter zu den entsprechenden Anwendungsorten bzw. Baustellen transportiert werden.Particularly preferred is an embodiment of the invention in which at least a portion of the pressure-sensitive adhesive coating is not covered with the cover film. Along the part of the pressure-sensitive adhesive coating of the tape according to the invention which is not covered by the cover film, the cover film does not have to be laboriously removed during the laying process, which results in faster processability of the tape according to the invention. Also, this prevents that possibly caused by the otherwise necessary removal of the film distortions and wrinkles in the adhered tape. Also, such inventively designed tape requires no additional assembly tape dispenser for receiving and dispensing the tape, since in the folded or rolled-up state, the tape according to the invention will not move in accordance with this preferred embodiment due to its partially free from the cover sheet pressure-sensitive adhesive coating. The tape is thus particularly easy and reliable usable. Also, the tape can thus be transported without special packaging and protection costs by the processor to the appropriate application or construction sites.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Haftkleberbeschichtung des Bandes zumindest im Bereich des ersten Faltabschnitts und/oder im Bereich des zweiten Faltabschnitts nicht mit der Abdeckfolie abgedeckt. Das heißt, der umgefaltete Bereich bzw. die umgefalteten Bereiche des erfindungsgemäßen Bandes trägt/tragen bevorzugt keine Abdeckfolie. Somit kann/können diese(r) Bereich(e) einfach unter beengten räumlichen Verhältnissen, beispielsweise in Kanten oder U-Profilen, ohne weitere Hilfsmittel und Arbeitsschritte, wie beispielsweise Abziehen der Abdeckfolie oder mühsames Umfalten, z.B. direkt von der Rolle abgerollt und angerieben werden, wodurch sich eine zuverlässige Abdichtwirkung bei weiter vereinfachter Verarbeitbarkeit ergibt. Diese einfache Form der Verarbeitung spart bis zur Hälfte der Arbeitszeit im Vergleich zur Verwendung von Bändern des bisherigen Standes der Technik.According to a preferred embodiment of the invention, the pressure-sensitive adhesive coating of the tape is not covered with the cover film, at least in the region of the first folding section and / or in the region of the second folding section. That is, the folded-over region or the folded-over regions of the band according to the invention preferably does not carry a cover film. Thus, this area (s) can be easily accommodated in confined spaces, such as in edgings or U-profiles, without further aids and operations, such as peeling off the cover sheet or tedious folding, e.g. be unrolled and rubbed directly from the roll, resulting in a reliable sealing effect with further simplified processability. This simple form of processing saves up to half the working time compared to the use of prior art bands.

Bevorzugt kann die jeweilige Breite des ersten und/oder zweiten Faltabschnitts oder die Breite der Faltabschnitte schmaler sein als die Breite des nicht umgefalteten Bandbereichs. Bevorzugt kann die jeweilige Breite des ersten und/oder zweiten Faltabschnitts oder die Breite der Faltabschnitte auch eine gleiche oder im wesentlichen gleiche Breite aufweisen wie die Breite des nicht umgefalteten Bandbereichs. Bevorzugt kann die jeweilige Breite des ersten und/oder zweiten Faltabschnitts oder die Breite der Faltabschnitte auch eine größere Breite aufweisen wie die Breite des nicht umgefalteten Bandbereichs. Die jeweilige Breite des ersten und/oder zweiten Faltabschnitts oder die Breite der Faltabschnitte kann bevorzugt mindestens 3 mm, bevorzugter mindestens 8 mm, noch bevorzugter mindestens 12 mm betragen und/oder kann weiter bevorzugt der Breite des nicht umgefalteten Bandbereichs entsprechen und/oder kann noch weiter bevorzugt größer sein als die Breite des nicht umgefalteten Bandbereichs.Preferably, the respective width of the first and / or second folding portion or the width of the folding portions may be narrower than the width of the unfolded band portion. Preferably, the respective width of the first and / or second folding portion or the width of the folding portions also have an equal or substantially equal width as the width of the unfolded band portion. Preferably, the respective width of the first and / or second folding section or the width of the folding sections can also have a greater width than the width of the unfolded belt area. The respective width of the first and / or second folding section or the width of the folding sections may preferably be at least 3 mm, more preferably at least 8 mm, more preferably be at least 12 mm and / or may more preferably correspond to the width of the unfolded belt area and / or may even more preferably be greater than the width of the unfolded belt area.

Um eine sichere Haftung des erfindungsgemäßen selbstklebenden Bandes auf unterschiedlichsten Materialien auch unter widrigen Witterungseinflüssen (Kälte, Feuchtigkeit) zu gewährleisten, und um unter allen Umständen eine möglichst zuverlässige Dichtwirkung des erfindungsgemäßen selbstklebenden Bandes zu erzielen, besteht die Trägerschicht gemäß einer bevorzugten Ausführungsform aus einem Material aus der Gruppe Papier, Kunststoff, Gewebe, Vlies oder einer Kombination zumindest zweier dieser Materialien, und besteht die Haftkleberbeschichtung aus zumindest einem Material der Gruppe selbstklebender Acrylatkleber, Kautschukkleber, Butylkleber, Hotmelt oder einer Kombination zumindest zweier dieser Kleber.In order to ensure a secure adhesion of the self-adhesive tape according to the invention on a variety of materials even under adverse climatic conditions (cold, moisture), and to achieve the most reliable sealing effect of the self-adhesive tape according to the invention under all circumstances, the carrier layer according to a preferred embodiment of a material the group of paper, plastic, fabric, non-woven or a combination of at least two of these materials, and the pressure-sensitive adhesive coating consists of at least one material of the group of self-adhesive acrylate adhesive, rubber adhesive, butyl adhesive, hot melt or a combination of at least two of these adhesives.

Die Verarbeitbarkeit des erfindungsgemäßen Bandes wird besonders erleichtert, falls das Band gemäß einer bevorzugten Ausführungsform so beschaffen ist, dass zumindest dessen Trägerschicht quer zur Längsrichtung des Bandes von Hand einreißbar ist. Bevorzugt kann auch die Abdeckfolie quer zur Längsrichtung des Bandes von Hand einreißbar sein. Somit kann ohne Werkzeugeinsatz ein Ablängen des Bandes bei der Verlegung auf einfache Art und Weise erfolgen.The processability of the tape according to the invention is particularly facilitated if, according to a preferred embodiment, the tape is such that at least its carrier layer can be torn by hand transversely to the longitudinal direction of the tape. Preferably, the cover film transverse to the longitudinal direction of the tape by hand can be torn. Thus, a cutting of the tape during installation can be done in a simple manner without tools.

Falls die Haftkleberbeschichtung des erfindungsgemäßen Bandes gemäß einer bevorzugten Ausführungsform einen nichtklebenden Mittelstreifen aufweist, so erleichtert dies besonders das Verkleben von Fugen zwischen zwei rechtwinklig aufeinanderstoßenden Bauelementen, da ein schiefes Verkleben mit Faltenwurf gerade im Stoßbereich dieser Bauelemente dadurch auf einfache Weise verhindert wird. Die Abdichtwirkung bleibt dabei in vollem Umfang erhalten, da die beiden Randbereiche des Bandes entsprechend verklebt werden können.If the pressure-sensitive adhesive coating of the tape according to the invention according to a preferred embodiment, a non-adhesive center strip, so this facilitates the bonding of joints between two perpendicularly abutting components, as an oblique sticking with drape especially in the joint area of these components is thereby prevented in a simple manner. The sealing effect is retained in full, since the two edge regions of the tape can be glued accordingly.

Besonders leicht handhabbar ist das erfindungsgemäße selbstklebende Band gemäß einer bevorzugten Ausführungsform, bei welcher das Band in gefaltetem Zustand zu einer Klebeband-Rolle aufgerollt ist. Diese ist vor Ort während der Anwendung auch ohne zusätzlichen Dispenser besonders leicht handhabbar.The self-adhesive tape according to the invention is particularly easy to handle according to a preferred embodiment in which the tape is rolled up in the folded state to an adhesive tape roll. This is particularly easy to handle on site during use without additional dispenser.

Gemäß einer bevorzugten Ausführungsform des erfindungsgemäßen Bandes ist mindestens an der Seite der ersten Faltungskante der Rolle eine Zwischenlage vorgesehen, durch welche gegebenenfalls ein Verkleben im Bereich der ersten Faltungskante vor der eigentlichen Anwendung des Bandes vermieden wird. Die Zwischenlage deckt im Bereich der ersten Faltungskante gegebenenfalls die dort freiliegende Haftkleberbeschichtung zuverlässig ab, so dass auch eine Schmutzansammlung bereits vor Anwendung des Bandes dort sicher vermieden wird. Die Verarbeitbarkeit des so vorteilhaft erfindungsgemäß gestalteten Bandes wird dadurch weiter verbessert.According to a preferred embodiment of the tape according to the invention, an intermediate layer is provided at least on the side of the first folding edge of the roll, by which, if necessary, sticking in the region of the first folding edge is avoided before the actual application of the tape. If necessary, the intermediate layer reliably covers the pressure-sensitive adhesive coating exposed there in the area of the first folding edge, so that even dirt accumulation is reliably avoided there before the tape is used. The processability of the so advantageously inventively designed band is thereby further improved.

Bevorzugt weist das erfindungsgemäße Band eine breite von mindestens 3 cm im nicht gefalteten Zustand auf, bevorzugter eine Breite im Bereich von 3 cm bis 50 cm, noch bevorzugter eine Breite im Bereich von 4 cm bis 30 cm und am meisten bevorzugt eine Breite im Bereich von 4,5 cm bis 20 cm. Diese Maße erlauben einerseits, auch etwas breitere Fugen sicher abzudichten, andererseits wird vermieden, dass durch übergroße Breite des erfindungsgemäßen Bandes dessen Handhabbarkeit erschwert wird und es somit zu Faltenbildung und damit zu Undichtheiten beim Verlegevorgang des erfindungsgemäßen Bandes kommt.Preferably, the tape of the invention has a width of at least 3 cm in the unfolded state, more preferably a width in the range of 3 cm to 50 cm, even more preferably a width in the range of 4 cm to 30 cm, and most preferably a width in the range of 4.5 cm to 20 cm. On the one hand, these dimensions make it possible to securely seal even slightly wider joints; on the other hand, it is avoided that the width of the strip according to the invention makes it difficult to handle and thus wrinkles and leaks in the laying process of the strip according to the invention.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung weist das Band zumindest einen Perforationsbereich mit Perforationsöffnungen auf, deren durchschnittlicher Durchmesser mindestens 3 mm beträgt. Mit einem derartigen selbstklebenden Band kann beispielsweise sichergestellt werden, dass der zumindest eine Perforationsbereich des Bandes überputzbar ist, wodurch sich eine besonders gute Verankerung ergibt, ohne die Abdichtwirkung des Bandes zu gefährden. Vorteilhafterweise kann der zumindest eine Perforationsbereich dabei an einem Randbereich des Bandes ausgestaltet sein, es ist jedoch auch möglich, beide Randbereiche des Bandes mit einem entsprechenden Perforationsbereich zu versehen. Insbesondere können die entsprechenden Randbereiche, welche als Perforationsbereiche ausgebildet sein können, auch den entsprechenden ersten und zweiten Faltabschnitten des Bandes entsprechen. Zumindest der Mittelstreifen des Bandes, welcher vorzugsweise nicht perforiert sein soll, sollte je nach Anwendungsfall jedoch breiter sein als die maximale Breite der abzudichtenden Fuge, um eine optimale Abdichtwirkung sicherzustellen. Dadurch, dass der perforierte Längsabschnitt des erfindungsgemäßen Bandes gemäß einer bevorzugten Ausführungsform sich an einem Randbereich des Bandes befindet und der Mittelstreifen unperforiert bleibt, wird verhindert, dass die Perforationsöffnungen zu Undichtheiten führen, wenn die abzudichtende Fuge mit dem entsprechend gestalteten selbstklebenden Band abgedeckt wird.According to a further preferred embodiment of the invention, the band has at least one perforation region with perforation openings whose average diameter is at least 3 mm. With such a self-adhesive tape, for example, it can be ensured that the at least one perforation region of the tape can be plastered over, which results in a particularly good anchoring, without jeopardizing the sealing effect of the tape. Advantageously, the at least one perforation region can be configured at an edge region of the band, but it is also possible for both To provide edge regions of the band with a corresponding perforation. In particular, the corresponding edge regions, which may be formed as perforation regions, also correspond to the corresponding first and second folding sections of the strip. However, depending on the application, at least the median strip of the band, which should preferably not be perforated, should be wider than the maximum width of the joint to be sealed in order to ensure an optimal sealing effect. Characterized in that the perforated longitudinal portion of the tape according to the invention according to a preferred embodiment is located at an edge region of the tape and the median strip remains unperforated, prevents the perforation openings lead to leaks when the joint to be sealed is covered with the correspondingly designed self-adhesive tape.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Trägerschicht, die Haftkleberbeschichtung und die abziehbare Abdeckfolie mit entsprechend durchgehenden Perforationsöffnungen perforiert. Solche Perforationsöffnungen sind kostengünstig durch entsprechende Ausstanzungen besonders einfach herstellbar, was zu günstigen Herstellungskosten führt. Generell verhindert die Abdeckfolie bzw. die Trägerschicht dabei, dass ein Perforationswerkzeug mit der Kleberschicht des selbstklebenden Bandes in Berührung kommt. Es ist jedoch generell auch möglich, dass des Klebebandes mit Perforationsöffnungen in dem Bereich versehen ist, welcher nicht mit der Abdeckfolie abgedeckt ist.According to a further advantageous embodiment of the invention, the carrier layer, the pressure-sensitive adhesive coating and the peelable cover film are perforated with correspondingly perforated perforations. Such perforation openings are cost particularly easy to produce by appropriate punched, which leads to low production costs. In general, the cover film or the carrier layer prevents a perforation tool from coming into contact with the adhesive layer of the self-adhesive tape. However, it is generally also possible for the adhesive tape to be provided with perforation openings in the area which is not covered by the covering film.

Bevorzugt können die Perforationsöffnungen im Wesentlichen rund, eckig oder oval ausgebildet sein.Preferably, the perforation openings may be substantially round, square or oval.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung kann die Trägerschicht aus einem solchen, insbesondere offenporigen Material bestehen, welches eine gute Hafteigenschaft für Mauerputz aufweist. Die Haftwirkung des Bandes auf Putzuntergrund wird damit zusätzlich verbessert und ein Ablösen von Teilen des Mauerputzes vom so gestalteten Band wird sicher vermieden.According to a further preferred embodiment of the invention, the carrier layer may consist of such, in particular open-pore material, which has a good adhesive property for plastering. The adhesive effect of the tape on plaster background is thus additionally improved and a detachment of parts of the plaster from the so-designed band is avoided.

Figur 1 zeigt eine erste bevorzugte Ausführungsform eines selbstklebenden Bandes gemäß der Erfindung in einer schematischen Schnittansicht entlang der Querrichtung des Bandes. Das erfindungsgemäße Band nach Fig. 1 weist eine Trägerschicht 1 an einer Bandoberseite, eine Haftkleberbeschichtung 2 der Trägerschicht 1 an der Bandunterseite und eine abziehbare Abdeckfolie 3 an der Bandunterseite auf. Ein erster Faltabschnitt 4 des Bandes ist in Querrichtung entlang einer in Längsrichtung des Bandes verlaufenden ersten Faltungskante 5 einmal umgefaltet und ein Teil der Haftkleberbeschichtung 2 ist entlang eines Längsabschnitts des Bandes nicht mit der Abdeckfolie 3 abgedeckt. Das Band kommt somit zumindest im umgefalteten Bereich auf sich selbst zu liegen, d.h. es ist auf sich selbst gefaltet. Gemäß Fig. 1 entspricht der Teil der Haftkleberbeschichtung 2, welcher nicht mit der Abdeckfolie 3 abgedeckt ist, dem Bereich des ersten Faltabschnitts 4. Ein erster Schlitz 11 der Abdeckfolie 3 ist in Längsrichtung des Bandes vorgesehen, wobei dieser erste Schlitz 11 nicht mit der ersten Faltungskante 5 zusammenfällt, sondern gemäß Fig. 1 im Wesentlichen mittig auf der Oberseite des gefalteten Bandes gemäß der Erfindung vorhanden ist. Ein Randabschnitt 9 der Abdeckfolie 3 steht über die erste Faltungskante 5 vor und dient damit als Angreifabschnitt zum Abziehen der Abdeckfolie 3.Figure 1 shows a first preferred embodiment of a self-adhesive tape according to the invention in a schematic sectional view along the transverse direction of the tape. The tape according to the invention according to FIG. 1 has a carrier layer 1 on a tape top side, a pressure-sensitive adhesive coating 2 of the carrier layer 1 on the underside of the tape and a removable cover film 3 on the underside of the tape. A first folded portion 4 of the tape is folded once in the transverse direction along a first folding edge 5 extending in the longitudinal direction of the tape, and part of the pressure-sensitive adhesive coating 2 is not covered with the covering sheet 3 along a longitudinal portion of the tape. The tape thus comes to lie at least in the folded area on itself, that is, it is folded on itself. 1, the part of the pressure-sensitive adhesive coating 2, which is not covered by the covering film 3, corresponds to the area of the first folding section 4. A first slot 11 of the covering film 3 is provided in the longitudinal direction of the belt, wherein this first slot 11 does not coincide with the first folding edge 5, but according to Fig. 1 substantially centrally on top of the folded strip according to the invention is present. An edge portion 9 of the cover film 3 projects beyond the first folding edge 5 and thus serves as an engaging portion for removing the cover film 3.

Ferner sind im nicht umgefalteten Bereich des in Fig. 1 dargestellten erfindungsgemäßen Bandes Perforationsöffnungen 10 vorgesehen, welche sich in einem Randbereich des Bandes durch die Trägerschicht 1, die Haftkleberbeschichtung 2 und die abziehbare Abdeckfolie 3 erstrecken.Furthermore, perforation openings 10 are provided in the unfolded region of the band according to the invention shown in FIG. 1, which openings extend in an edge region of the band through the carrier layer 1, the pressure-sensitive adhesive coating 2 and the peelable cover film 3.

Generell sei angemerkt, dass die Darstellung der Fig. 1, wie auch die weiteren Darstellungen, nicht maßstabsgerecht sind und lediglich schematisch den Aufbau und die Gestaltung der Ausführungsformen des erfindungsgemäßen Bandes zeigt. Insbesondere die Dickenverhältnisse der einzelnen Schichten sind nicht maßstabsgerecht wiedergegeben. Allgemein weist das erfindungsgemäße Band bevorzugt eine Breite im nicht gefalteten Zustand von mindestens 3 cm auf. Die Perforationsöffnungen 10 haben einen durchschnittlichen Durchmesser von mindestens 3 mm.In general, it should be noted that the representation of FIG. 1, as well as the other illustrations, are not to scale and only schematically shows the structure and the design of the embodiments of the tape according to the invention. In particular, the thickness ratios of the individual layers are not reproduced to scale. Generally, the tape according to the invention preferably has a width in the unfolded state of at least 3 cm.

Gemäß der in Fig. 1 dargestellten Ausführungsform ist das erfindungsgemäße Band so auf sich selbst gefaltet, dass der erste Faltabschnitt 4 die gleiche Breite aufweist wie der nicht gefaltete, in Fig. 1 oben angeordnete, Abschnitt des erfindungsgemäßen Bandes.According to the embodiment shown in Fig. 1, the tape according to the invention is folded on itself, that the first folding portion 4 has the same width as the unfolded, in Fig. 1 above arranged, section of the tape according to the invention.

Figur 2 zeigt in einer schematischen Querschnittansicht entlang der Querrichtung des erfindungsgemäßen Bandes eine zweite Ausführungsform der Erfindung. In Fig. 2, wie auch in den übrigen Figuren, bezeichnen gleiche Bezugszeichen gleiche Elemente der Erfindung. Die in Figur 2 dargestellte Ausführungsform der Erfindung entspricht im Wesentlichen der in Figur 1 dargestellten Ausführungsform der Erfindung, mit dem Unterschied, dass der erste Faltabschnitt 4 nicht die gleiche Breite aufweist wie der nicht gefaltete Abschnitt. In der in Figur 2 gezeigten Ausführungsform weist der erste Faltabschnitt 4 eine Breite auf, welche in etwa einem Drittel der Breite des nicht gefalteten, in Fig. 2 oben angeordneten, Abschnitts bzw. Bereichs des erfindungsgemäßen Bandes entspricht.FIG. 2 shows, in a schematic cross-sectional view along the transverse direction of the strip according to the invention, a second embodiment of the invention. In Fig. 2, as in the other figures, like reference numerals designate like elements of the invention. The embodiment of the invention shown in FIG. 2 essentially corresponds to the embodiment of the invention shown in FIG. 1, with the difference that the first folding section 4 does not correspond to the embodiment shown in FIG same width as the unfolded section. In the embodiment shown in FIG. 2, the first folding section 4 has a width which corresponds approximately to one third of the width of the unfolded section or region of the strip according to the invention arranged at the top in FIG.

Figur 3 zeigt in einer schematischen Querschnittansicht entlang der Querrichtung des erfindungsgemäßen Bandes eine weitere Ausführungsform der Erfindung. In Fig. 3, wie auch in den übrigen Figuren, bezeichnen gleiche Bezugszeichen gleiche Elemente der Erfindung.FIG. 3 shows, in a schematic cross-sectional view along the transverse direction of the strip according to the invention, a further embodiment of the invention. In Fig. 3, as in the other figures, like reference numerals designate like elements of the invention.

In Fig. 3 ist eine Ausführungsform der Erfindung gezeigt, bei welcher ein erster Faltabschnitt 4 des Bandes in Querrichtung entlang einer in Längsrichtung des Bandes verlaufenden ersten Faltungskante 5 umgefaltet ist und ein zweiter Faltungsabschnitt 6 in Querrichtung entlang einer in Längsrichtung des Bandes verlaufenden zweiten Faltungskante 7 umgefaltet ist. Beide Faltungsabschnitte sind dabei Längsabschnitte des Bandes, welche nicht mit der Abdeckfolie 3 abgedeckt sind. Es handelt sich sowohl beim ersten Faltungsabschnitt 4 als auch beim zweiten Faltungsabschnitt 6 um Randabschnitte des Bandes, welche von ihren Ausmaßen dergestalt ausgewählt sind, dass sie zusammen in etwa der verbleibenden, nicht umgefalteten Breite des selbstklebenden Bandes gemäß der Erfindung entsprechen. Sowohl der erste Faltungsabschnitt als auch der zweite Faltungsabschnitt weisen dabei als Randbereiche des erfindungsgemäßen Bandes eine Breite auf, welche im Wesentlichen einem Viertel der Gesamtbreite des Bandes im ungefalteten Zustand entspricht. Die Abdeckfolie 3 des Bandes weist zwei Randabschnitte 9 der Abdeckfolie 3 auf, welche jeweils über die erste Faltungskante 5 und die zweite Faltungskante 7 vorstehen. Somit werden Angreifabschnitte gebildet, welche das Abziehen der Abdeckfolie 3 ermöglichen. Ein erster Schlitz 11 ist vorgesehen, welcher weder mit der ersten Faltungskante 5 noch mit der zweiten Faltungskante 7 zusammenfällt. Der erste Schlitz 11 ist erfindungsgemäß in etwa in der Mitte des Bandes im gefalteten Zustand angeordnet, er kann sich jedoch generell je nach konkreter Produktgestaltung an jeder anderen Stelle geeigneter Weise befinden.FIG. 3 shows an embodiment of the invention in which a first folding section 4 of the strip is folded transversely along a first folding edge 5 extending in the longitudinal direction of the strip and a second folding section 6 in the transverse direction along a second folding edge 7 extending in the longitudinal direction of the strip folded over. Both folding sections are longitudinal sections of the band, which are not covered with the cover 3. Both the first folding section 4 and the second folding section 6 are edge portions of the tape which are selected from their dimensions such that together they approximately correspond to the remaining unfolded width of the self-adhesive tape according to the invention. In this case, both the first folding section and the second folding section have, as edge regions of the tape according to the invention, a width which essentially corresponds to one fourth of the total width of the tape in the unfolded state. The covering film 3 of the band has two edge sections 9 of the covering film 3, which project in each case over the first folding edge 5 and the second folding edge 7. Thus, engaging portions are formed, which allow the removal of the cover 3. A first slot 11 is provided, which coincides neither with the first folding edge 5 nor with the second folding edge 7. The first slot 11 is according to the invention arranged approximately in the middle of the band in the folded state, but it can in general, depending on the specific product design in any other appropriate location.

Figur 4 zeigt schematisch eine vierte Ausführungsform des erfindungsgemäßen Bandes im Querschnitt. Im Wesentlichen entspricht die Ausführungsform gemäß Fig. 4 der Ausführungsform der Fig. 3. Der Unterschied besteht darin, dass gemäß Fig. 4 die Abdeckfolie 3 auch den Bereich des zweiten Faltungsabschnitts 6 abdeckt bzw. die dortige Haftkleberbeschichtung 2 abdeckt. Im Bereich des zweiten Faltungsabschnitts 6 weist das Band ferner die bereits im Zusammenhang mit Fig. 1 beschriebenen Perforationsöffnungen 10 auf. Zusätzlich vorgesehen ist ein zweiter Schlitz 8 der Abdeckfolie 3, welcher in Längsrichtung des Bandes verläuft und gemäß der in Fig. 4 dargestellten Ausführungsform mit der zweiten Faltungskante 7 zusammenfällt. Somit kann im Bereich des zweiten Faltungsabschnitts 6 die Abdeckfolie 3 entlang des Schlitzes 8 entfernt werden. Die sonstigen Elemente des in Fig. 4 gezeigten Bandes entsprechen den Elementen, wie sie bereits in den anderen Figuren beschrieben worden sind.Figure 4 shows schematically a fourth embodiment of the tape according to the invention in cross section. In essence, the embodiment according to FIG. 4 corresponds to the embodiment of FIG. 3. The difference is that according to FIG. 4, the covering film 3 also covers the region of the second folding section 6 or covers the pressure-sensitive adhesive coating 2 there. In the region of the second folding section 6, the band also has the perforation openings 10 already described in connection with FIG. In addition, a second slot 8 of the covering film 3 is provided, which runs in the longitudinal direction of the band and, according to the embodiment shown in FIG. 4, coincides with the second folding edge 7. Thus, in the region of the second folding section 6, the covering film 3 can be removed along the slot 8. The other elements of the band shown in Fig. 4 correspond to the elements as they have already been described in the other figures.

Figur 5 zeigt in einer schematischen Querschnittansicht entlang der Querrichtung des erfindungsgemäßen Bandes eine fünfte Ausführungsform der Erfindung. In Fig. 5, wie auch in den übrigen Figuren, bezeichnen gleiche Bezugszeichen gleiche Elemente der Erfindung. Die in Figur 5 dargestellte Ausführungsform der Erfindung entspricht im Wesentlichen der in Figur 4 dargestellten Ausführungsform der Erfindung, mit dem Unterschied, dass der erste Faltabschnitt 4 und der zweite Faltabschnitt 6 jeweils nicht die gleiche Breite aufweisen, welche im Wesentlichen einem Viertel der Gesamtbreite des Bandes im ungefalteten Zustand entspricht. In der in Figur 5 gezeigten Ausführungsform weist der erste Faltabschnitt 4 eine bezüglich der Breite des zweiten Faltabschnitts 6 geringere Breite auf, welche bevorzugt in etwa der Hälfte der Breite des zweiten Faltabschnitts 6 entspricht. Die sonstigen Elemente des in Fig. 5 gezeigten Bandes entsprechen den Elementen, wie sie bereits zur Figur 4 beschrieben worden sind.Figure 5 shows in a schematic cross-sectional view along the transverse direction of the tape according to the invention, a fifth embodiment of the invention. In Fig. 5, as in the other figures, like reference numerals designate like elements of the invention. The embodiment of the invention shown in FIG. 5 essentially corresponds to the embodiment of the invention shown in FIG. 4, with the difference that the first folding section 4 and the second folding section 6 each do not have the same width, which is substantially one quarter of the total width of the strip in the unfolded state corresponds. In the embodiment shown in FIG. 5, the first folding section 4 has a smaller width relative to the width of the second folding section 6, which preferably corresponds approximately to half the width of the second folding section 6. The other elements of the band shown in Fig. 5 correspond to the elements as they have already been described for Figure 4.

Figur 6 zeigt eine weitere bevorzugte Ausführungsform des erfindungsgemäßen Bandes in einer schematischen Querschnittdarstellung in Querrichtung des Bandes.FIG. 6 shows a further preferred embodiment of the strip according to the invention in a schematic cross-sectional representation in the transverse direction of the strip.

Auch Fig. 6 zeigt eine Ausführungsform des erfindungsgemäßen Bandes, bei welcher sowohl ein erster Faltungsabschnitt 4 als auch ein zweiter Faltungsabschnitt 6 vorgesehen sind. Anders als in den in Fig. 3, 4 und 5 gezeigten Ausführungsformen der Erfindung, sind der erste Faltabschnitt 4 und der zweite Faltabschnitt 6 jedoch nicht gegenüberliegende Randabschnitte des Bandes, sondern der erste Faltabschnitt 4 und der zweite Faltabschnitt 6 grenzen in Querrichtung des Bandes gesehen aneinander an. Ferner ist der zweite Faltabschnitt 6 auf den ersten Faltabschnitt 4 so gefaltet, dass diese aufeinander liegen. Gemäß Fig. 6 weisen sowohl der erste Faltabschnitt 4 als auch der zweite Faltabschnitt 6 keine die Haftkleberbeschichtung 2 abdeckende Abdeckfolie 3 auf. Wie auch in den übrigen dargestellten Ausführungsformen der Erfindung weist die Abdeckfolie 3 des erfindungsgemäßen Bandes einen ersten Schlitz 11 auf, welcher nicht mit der ersten Faltungskante 5 und auch nicht mit der zweiten Faltungskante 7 zusammenfällt.Also, Fig. 6 shows an embodiment of the tape according to the invention, in which both a first folding section 4 and a second folding section 6 are provided. Unlike the embodiments of the invention shown in FIGS. 3, 4 and 5, however, the first folding section 4 and the second folding section 6 are not opposite edge portions of the tape, but the first folding section 4 and the second folding section 6 are seen in the transverse direction of the tape to each other. Further, the second folding portion 6 is folded on the first folding portion 4 so that they lie on each other. According to FIG. 6, both the first folding section 4 and the second folding section 6 do not have the covering film 3 covering the pressure-sensitive adhesive coating 2. As in the other illustrated embodiments of the invention, the cover 3 of the tape according to the invention has a first slot 11 which does not coincide with the first folding edge 5 and also not with the second folding edge 7.
