Definitions
- the present invention relates to a sealing tape for sealing joints.
- sealing tapes are commonly used for sealing joints, for example, between a frame profile of a window or a door and a building wall to seal the joints against draft and driving rain. Additionally provided films on a side surface of the sealing tape also increase the vapor impermeability of the same, see, for example EP 0 072 955 A1 or EP 1 936 246 A1 , However, films which are attached to the outside of the sealing tape, have the disadvantage that they can be damaged during transport or installation of the sealing tape.
- a sealing strip roll which has at least one barrier layer extending in the radial direction, which is arranged between two layers of the foam and thus in the interior of the sealing strip roll.
- the barrier layer consists of adhesive or of a lamination material.
- large-area barrier layers are formed on plates of an open-pore foam material by lamination or gluing. Multiple layers of foam boards and barrier layers form laminate blocks. These laminate blocks are separated into sheets orthogonal to the large-area barrier layers.
- the panels are then wound into wide rollers such that the barrier layers and the foam material are lined up on the circumference of the rollers in the axial direction. Such a wide roll is then separated between the individual barrier layers into slices to form several sealing tape rolls. This method requires many complex steps and the length of the sealing strips produced is limited by the size limitation of automatically machinable laminate blocks.
- the present invention has for its object to provide a sealing tape with an inner barrier layer, which has variable properties and can be produced with reduced energy requirements.
- the sealing tape according to the invention for sealing a joint comprises two longitudinal side flanks, wherein a direction transverse to the side flanks defines a functional direction of the sealing tape.
- the sealing strip has at least a first foam strip and a second foam strip made of a resilient foam which can be restored after compression, which are not formed integrally with one another and are arranged side by side in the functional direction, each foam strip having an upper side, a lower side and an inner side edge facing the other foam strip ,
- the sealing tape also includes a barrier layer disposed between the first foam strip and the second foam strip such that it reduces vapor transmission permeability of the sealing tape in the operative direction, the barrier layer being adhesively bonded to both the first foam strip and the second foam strip, and wherein the barrier layer is at least partially formed from a first film strip.
- In an area between the first foam strip and the second foam strip and at least including the first film strip of the barrier layer at least one longitudinal pocket or at least one longitudinal cavity is formed, which is completely enclosed on at least four sides, wherein the
- a sealing tape in which a barrier layer is arranged protected inside the sealing tape and in which the properties of the barrier layer can be made variable.
- a desired additional material is received in the pocket or the cavity in order to give the sealing tape special properties.
- traps between the first film strip of the barrier layer and the first foam strip are only in an upper region of the first foam strip on top of the first foam strip and / or on the inner side edge of the first foam strip near the top of the first foam strip and in a lower region of the first Foam strip disposed on the underside of the first foam strip and / or on the inner side edge of the first foam strip near the bottom of the first foam strip, while in a middle region between the upper portion and the lower portion of the first foam strip, the first film strip of the barrier layer not with the first foam strip is arrested.
- the sealing tape can be simple and are manufactured inexpensively, and the expansion of the sealing tape is not limited despite the presence of the barrier layer.
- the detents between the first film strip and the first foam strip are located only on the inner side flank of the first foam strip near the top of the first foam strip and on the inner side flank of the first foam strip near the bottom of the first foam strip. In this way, in the production of the sealing tape already a short-term heating from above and from below enough to form the traps.
- the longitudinal pocket is formed at the level of the central region of the first foam strip.
- the pocket is enclosed by the first film strip and the first foam strip. In this way, the pocket is produced automatically in the production of sealing tape if the points of adhesion between the first film strip and the first foam strip are present only in the upper region and in the lower region of the first foam strip.
- the first film strip may be fully adhered to the inner side edge of the second foam strip.
- the first film strip may be adhered to the top and / or bottom of the second foam strip.
- a particularly simple production of the sealing tape is obtained when the adhesion points between the first film strip and the second foam strip are arranged only on the inner side edge of the second foam strip near the top of the second foam strip and on the inner side edge of the second foam strip near the bottom of the second foam strip. In this way, the traps between the first film strip and the first foam strip and the traps between the first film strip and the second foam strip can be produced simultaneously in the same process step.
- the first film strip may be fully adhered to the inner side edge of the second foam strip, and the detents between the film strip and the first foam strip are disposed on the top and bottom of the first foam strip.
- the barrier layer of the sealing tape has, in addition to the first film strip, a second film strip which is adhesively bonded to the second foam strip.
- the first film strip is adhesively bonded to the second film strip, and traps between the first film strip and the second film strip are disposed only in an area near the top of the first foam strip and in a region near the bottom of the first foam strip, while in an intermediate region between the traps of the first film strip and the second film strip are not arrested with each other.
- the foam strips can already be equipped in an upstream production step with the first film strip and the second film strip, and the arrest of the two equipped foam strips takes place only by arresting the two film strips in a later process step.
- the longitudinal pocket is formed in the intermediate region between the adhesion points and thus between the first film strip and the second film strip.
- the barrier layer has a longitudinal tubular body formed at least in part from the first film strip, the tubular body forming the cavity in its interior and being adhered to both the first foam strip and the second foam strip.
- the pocket or the cavity is enclosed by all six sides.
- the barrier layer has a tear tab, which can be opened by pulling on the tear tab, the pocket or the cavity.
- the contents of the pocket or the cavity can be selectively released or activated, for example, only after installation of the sealing tape.
- two reactive materials can be selectively associated with each other, which were previously stored separately in different chambers of the cavity or the bag.
- the adhesion points are formed as longitudinal adhesive lines. As a result, a continuous arrest of the two foam strips is guaranteed to each other, which can also be generated in a simple manner.
- a particularly simple production of the sealing tape according to the invention is ensured if the traps are formed by melting and subsequent curing of a bonding material, in particular an adhesive.
- FIG. 1 to 16 By way of example, various embodiments of the sealing tape 2 according to the invention are shown schematically in cross-sectional view in a completely relaxed state. It should be clarified that the individual elements of the sealing tape 2 shown in the figures are drawn at a distance from each other in order to contribute to the clarity and to be able to designate the individual elements better. In reality, the individual elements of the sealing tape 2 (except the cavity 150 in FIG Fig. 13 to 16 ) each closely to each other.
- the traps 132 are drawn for reasons of clarity as block-shaped elements, but are in reality usually flat, almost point-like, linear or planar structures that produce a close neighborhood between each adjacent to them elements.

- the functional direction F runs in the transverse direction of the sealing strip 2 from one side flank 104 of the sealing strip to the other side flank 104.
- the width of the sealing tape 2 in the transverse direction between the outer side edges 104 is usually between 5 mm and 20 cm, preferably between 1 cm and 12 cm.
- the width of a foam strip 114, 116 is preferably between 2.5 and 150 mm, more preferably between 10 and 80 mm.
- the height of the foam strips 114, 116 in the relaxed state is usually between 5 mm and 150 mm, more preferably between 10 mm and 80 mm.
- the first foam strip 114 may also have a different width and / or height than the second foam strip 116.
- foams for the foam strips 114, 116 it is possible to use all known open-celled, mixed-celled or closed-cell flexible foams made of e.g. Polyurethane, polyethylene, polyvinyl chloride or polypropylene are used, which make a provision after compression.
- the first foam strip 114 may be made of a different foam material than the second foam strip 116.
- the first foam strip 114 and the second foam strip 116 may be impregnated with different impregnate or only the first foam strip 114 or only the second foam strip 116 may be impregnated.
- the first foam strip 114 may have a different color than the second foam strip 116. As a result, for example, a marking of the preferred installation direction of the sealing tape 2 can be made.
- the first foam strip 114 and the second foam strip 116 are configured substantially identical, in particular have the same height and width.
- the two foam strips 114, 116 are not integrally formed with each other, ie there is no connecting web of the foam material between the two foam strips 114, 116. Rather, the two foam strips 114, 116 are only directly or indirectly arrested with each other.
- the first foam strip 114 has a rectangular cross-section in the illustrated example case.
- the first foam strip 114 includes an upper surface 118, a lower surface 120, and an inner side flank 122 facing the second foam strip 116. Opposite the inner side flank 122 of the first foam strip 114, the first foam strip 114 has an outer side flank connected to the side flank 104 of the sealing strip 2 coincides.
- the second foam strip 116 also has a rectangular cross-section in the illustrated example.
- the second foam strip 116 comprises an upper side 124, a lower side 126 and an inner side edge 128 facing the first foam strip 114.
- the outer side flank of the second foam strip 116 lying opposite the inner side flank 128 at the same time forms the second side flank 104 of the sealing strip 2.
- each of the foam strips 114, 116 may also have a different cross-sectional shape, in which the top 118, 124 of one or both foam strips 114, 116 is provided with an arbitrarily shaped profile.
- a barrier layer 30 (FIG. Fig. 17 ), which comprises at least one film strip 130.
- the barrier layer 30 is arranged such that it reduces or even completely excludes a vapor diffusion permeability of the sealing strip in the functional direction F.
- the film strip 130 is preferably made of plastic (polyamide, polyethylene, polypropylene, polyurethane, etc.). But there are also all other materials in question, which are suitable to reduce the passage of air or vapor diffusion through the sealing tape 2. Complete blockage against passage of air or against vapor diffusion is possible but not necessarily necessary. It may be expedient if the foil strip 130 is moisture-variable in such a way that it is more diffusion-tight at high humidity than at low atmospheric humidity or vice versa.
- the film strip 130 extends vertically over the entire inner side edge 128 of the second foam strip 116.
- the film strip 130 is in the illustrated example over an adhesive surface 131 over the entire surface with the inner side edge 128 of the second foam strip 116 arrested.
- the adhesive surface 131 is preferably formed by lamination.
- the film strip 130 is connected to the first foam strip 114 only via specific adhesion points 132.
- the traps 132 are located in the illustrated example of the Fig. 1 only in an upper region 117 of the first foam strip 114 on the inner side edge 122 of the first foam strip 114 near the top 118 of the first foam strip 114 and in a lower region 119 of the first foam strip 114 on the inner side edge 122 of the first foam strip 114 near the bottom 120th In contrast, in a middle region 121 between the upper region 117 and the lower region 119 of the first foam strip 114, the film strip 130 is not adhered to the first foam strip 114.
- the upper region 117, the middle region 121 and the lower region 119 of the first foam strip 114 are each identified by the dotted lines.
- the height of the center region 121 is preferably at least 10% of the height of the entire sealing tape, more preferably at least 20%, more preferably at least 30%, more preferably at least 40%, more preferably at least 50%, more preferably at least 60 %.
- the upper portion 117 and the lower portion 119 are preferably less high and preferably substantially of the same height.
- the adhesion points 132 are preferably formed as continuous adhesive lines in the longitudinal direction of the sealing strip 2, so that between the adhesion points 132 a pocket 134 is formed, which is completely enclosed on at least four sides by other elements of the sealing strip 2.
- the film strip 130 and the inner side edge 122 of the first foam strip 114 (supported by the adhesive points 132) form the boundaries of the pocket 134.
- the pocket 134 does not have a large extent in the transverse direction. Rather, the pocket 134 will in practice only be perceived as a narrow slot between the two foam strips 114, 116. Typically, the pocket 134 is accessible from the front and back, i. in the two directions out of the drawing plane and into the drawing plane.
- the traps 132 are preferably formed by melting and then curing an adhesive. It is particularly preferred if the hotmelt adhesive is integrated as a component, for example in layer form, in the film strip 130 and is thus activated during the production process merely by heating and subsequent hardening. In this way, the application of an additional adhesive material can be omitted. It is likewise preferred if the film strip 130 itself has thermoplastic adhesive properties and thus the material of the film strip 130 is melted by heating, adhesively bonds with adjacent elements and subsequently hardens.
- each film strip 130 is permanently elastic, so that it remains permanently elastic even after storage of the sealing tape 2 in the compressed state in the recovery of the sealing tape 2 and in the installed state of the sealing tape 2 in a joint always tight against the joint flanks.
- an adhesive layer 80 is also applied, which is covered by a release liner 81.
- the adhesive layer 80 serves to attach the sealing tape 2 to the component to be sealed, as described later with reference to FIG Fig. 13 will be described in more detail.
- Such adhesive layer 80 with release liner 81 is preferably also in the embodiments of Fig. 2 to 12 present, but there is no longer shown for reasons of clarity.
- the film strip 130 not only extends over the inner side edge 128 of the second foam strip 116, but is also folded over the top 124 and the bottom 126 of the second foam strip 116 and there also adhered by means of adhesive surfaces 131.
- Fig. 3 illustrated variant of the sealing tape 2 of the invention substantially corresponds to the embodiment of Fig. 2 wherein the film strip 130 is adhered to only the top 124 and the bottom 126 of the second foam strip 116, while it is no longer adhered to the inner side edge 128 of the second foam strip 116.
- Fig. 4 illustrated variant of the sealing tape 2 of the invention substantially corresponds to the embodiment of Fig. 1 , wherein the film strip 130 is no longer completely adhered to the inner side edge 128 of the second foam strip 116, but only via adhesion points 132. These catches 132 are on the inner side edge 128 of the second foam strip 116 near the top 124 of the second foam strip 116 and on the inner side edge 128 of the second foam strip 116 near the bottom 126 of the second foam strip 116 is arranged.
- the film strip 130 is already provided on both sides with a melt adhesive layer, so that all the adhesive sites 132 are formed simultaneously when heated and then cured.
- Fig. 5 illustrated variant of the sealing tape 2 of the invention substantially corresponds to the embodiment of Fig. 4 in that between the film strip 130 and the second foam strip 116 as part of the barrier layer 30, a second film strip 136 is inserted, which in turn is adhered to the second foam strip 116 via adhesion points 132.
- the material of the second film strip 136 is preferably selected from the same materials that may be used as the material for the film strip 130.
- the second film strip 136 is thus adhered to the second strip of foam 116 via adhesion points 132 on one side and to the film strip 130 on the other side.
- the adhesion between the second film strip 136 and the second foam strip 116 may also be over the entire surface on the inner side edge 128 of the second Foam strip 116 done.
- two further pockets are formed: one between the two film strips 130 and 136, and another between the second film strip 136 and the second foam strip 116 ,
- the design is similar to the embodiment Fig. 5 , wherein only one foil strip 130 is provided, which is arranged in a U-shaped manner between the two foam strips 114, 116 and whose legs are respectively adhesively bonded to the inner side edge 122 of the first foam strip 114 and to the inner side edge 128 of the second foam strip 116 ,
- the two legs of the film strip 130 still be arrested by means of a further adhesion point 132 in an upper region of the sealing tape 2 with each other.
- Fig. 7 illustrated variant of the sealing tape 2 of the invention substantially corresponds to the embodiment of Fig. 1 wherein the film strip 130 is not adhered to the inner side edge 122 of the first foam strip 114, but is merely adhered to the first foam strip 114 by adhesions 132 disposed on the upper surface 118 and lower surface 120 of the first foam strip 114.
- Fig. 8 illustrated variant of the sealing tape 2 according to the invention corresponds to the embodiment of Fig. 1 wherein the bag 134 is filled with a filler 140.
- Suitable additional material 140 are, in particular, contiguous materials which can be introduced into the pocket 134 in one piece.
- Flowable or liquid materials are only suitable if the pocket 134 is additionally closed in a direction out of the plane of the drawing and into the plane of the drawing, i. when the bag 134 is enclosed by all six sides.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.
Das erfindungsgemäße Dichtband zum Abdichten einer Fuge umfasst zwei längslaufende Seitenflanken, wobei eine Richtung quer zu den Seitenflanken eine Funktionsrichtung des Dichtbands definiert. Das Dichtband weist mindestens einen ersten Schaumstoffstreifen und einen zweiten Schaumstoffstreifen aus einem nach Kompression rückstellfähigen Weichschaumstoff auf, die nicht einstückig miteinander ausgebildet sind und in Funktionsrichtung nebeneinander angeordnet sind, wobei jeder Schaumstoffstreifen eine Oberseite, eine Unterseite und eine innere, dem anderen Schaumstoffstreifen zugewandte Seitenflanke aufweist. Das Dichtband weist außerdem eine Sperrschicht auf, die zwischen dem ersten Schaumstoffstreifen und dem zweiten Schaumstoffstreifen derart angeordnet ist, dass sie eine Dampfdiffusionsdurchlässigkeit des Dichtbands in Funktionsrichtung reduziert, wobei die Sperrschicht sowohl mit dem ersten Schaumstoffstreifen als auch mit dem zweiten Schaumstoffstreifen haftend verbunden ist, und wobei die Sperrschicht zumindest teilweise aus einem ersten Folienstreifen gebildet ist. In einem Bereich zwischen dem ersten Schaumstoffstreifen und dem zweiten Schaumstoffstreifen und zumindest unter Einbeziehung des ersten Folienstreifens der Sperrschicht ist mindestens eine längslaufende Tasche oder mindestens ein längslaufender Hohlraum gebildet, die bzw. der an mindestens vier Seiten vollständig umschlossen ist, wobei die Tasche oder der Hohlraum mit einem Zusatzmaterial gefüllt ist.The sealing tape according to the invention for sealing a joint comprises two longitudinal side flanks, wherein a direction transverse to the side flanks defines a functional direction of the sealing tape. The sealing strip has at least a first foam strip and a second foam strip made of a resilient foam which can be restored after compression, which are not formed integrally with one another and are arranged side by side in the functional direction, each foam strip having an upper side, a lower side and an inner side edge facing the other foam strip , The sealing tape also includes a barrier layer disposed between the first foam strip and the second foam strip such that it reduces vapor transmission permeability of the sealing tape in the operative direction, the barrier layer being adhesively bonded to both the first foam strip and the second foam strip, and wherein the barrier layer is at least partially formed from a first film strip. In an area between the first foam strip and the second foam strip and at least including the first film strip of the barrier layer at least one longitudinal pocket or at least one longitudinal cavity is formed, which is completely enclosed on at least four sides, wherein the pocket or the cavity filled with an additional material.
Mit dieser Ausgestaltung wird ein Dichtband geschaffen, bei dem eine Sperrschicht im Inneren des Dichtbands geschützt angeordnet ist und bei dem die Eigenschaften der Sperrschicht variabel gestaltet werden können. Erfindungsgemäß wird in der Tasche oder dem Hohlraum ein gewünschtes Zusatzmaterial aufgenommen, um dem Dichtband spezielle Eigenschaften zu verleihen.With this embodiment, a sealing tape is provided in which a barrier layer is arranged protected inside the sealing tape and in which the properties of the barrier layer can be made variable. According to the invention, a desired additional material is received in the pocket or the cavity in order to give the sealing tape special properties.
Vorzugsweise sind Haftstellen zwischen dem ersten Folienstreifen der Sperrschicht und dem ersten Schaumstoffstreifen lediglich in einem oberen Bereich des ersten Schaumstoffstreifens auf der Oberseite des ersten Schaumstoffstreifens und/oder an der inneren Seitenflanke des ersten Schaumstoffstreifens nahe der Oberseite des ersten Schaumstoffstreifens und in einem unteren Bereich des ersten Schaumstoffstreifens auf der Unterseite des ersten Schaumstoffstreifens und/oder an der inneren Seitenflanke des ersten Schaumstoffstreifens nahe der Unterseite des ersten Schaumstoffstreifens angeordnet, während in einem Mittelbereich zwischen dem oberen Bereich und dem unteren Bereich des ersten Schaumstoffstreifens der erste Folienstreifen der Sperrschicht nicht mit dem ersten Schaumstoffstreifen verhaftet ist. Auf diese Weise kann das Dichtband einfach und kostengünstig hergestellt werden, und die Expansion des Dichtbands ist trotz Vorliegens der Sperrschicht nicht eingeschränkt.Preferably, traps between the first film strip of the barrier layer and the first foam strip are only in an upper region of the first foam strip on top of the first foam strip and / or on the inner side edge of the first foam strip near the top of the first foam strip and in a lower region of the first Foam strip disposed on the underside of the first foam strip and / or on the inner side edge of the first foam strip near the bottom of the first foam strip, while in a middle region between the upper portion and the lower portion of the first foam strip, the first film strip of the barrier layer not with the first foam strip is arrested. In this way, the sealing tape can be simple and are manufactured inexpensively, and the expansion of the sealing tape is not limited despite the presence of the barrier layer.
Vorzugsweise sind die Haftstellen zwischen dem ersten Folienstreifen und dem ersten Schaumstoffstreifen lediglich an der inneren Seitenflanke des ersten Schaumstoffstreifens nahe der Oberseite des ersten Schaumstoffstreifens und an der inneren Seitenflanke des ersten Schaumstoffstreifens nahe der Unterseite des ersten Schaumstoffstreifens angeordnet. Auf diese Weise genügt bei der Herstellung des Dichtbands bereits eine kurzfristige Erwärmung von oben und von unten, um die Haftstellen zu bilden.Preferably, the detents between the first film strip and the first foam strip are located only on the inner side flank of the first foam strip near the top of the first foam strip and on the inner side flank of the first foam strip near the bottom of the first foam strip. In this way, in the production of the sealing tape already a short-term heating from above and from below enough to form the traps.
Vorzugsweise ist die längslaufende Tasche auf Höhe des Mittelbereichs des ersten Schaumstoffstreifens ausgebildet.Preferably, the longitudinal pocket is formed at the level of the central region of the first foam strip.
In einer Ausführungsvariante ist die Tasche von dem ersten Folienstreifen und dem ersten Schaumstoffstreifen umschlossen. Auf diese Weise wird die Tasche bei der Dichtbandherstellung automatisch erzeugt, wenn die Haftstellen zwischen dem ersten Folienstreifen und dem ersten Schaumstoffstreifen lediglich im oberen Bereich und im unteren Bereich des ersten Schaumstoffstreifens vorliegen.In one embodiment variant, the pocket is enclosed by the first film strip and the first foam strip. In this way, the pocket is produced automatically in the production of sealing tape if the points of adhesion between the first film strip and the first foam strip are present only in the upper region and in the lower region of the first foam strip.
In besonderen Ausgestaltungen kann der erste Folienstreifen vollflächig an der inneren Seitenflanke des zweiten Schaumstoffstreifens verhaftet sein.In special embodiments, the first film strip may be fully adhered to the inner side edge of the second foam strip.
Alternativ oder zusätzlich kann der erste Folienstreifen an der Oberseite und/oder der Unterseite des zweiten Schaumstoffstreifens verhaftet sein.Alternatively or additionally, the first film strip may be adhered to the top and / or bottom of the second foam strip.
Eine besonders einfache Herstellung des Dichtbands ergibt sich, wenn Haftstellen zwischen dem ersten Folienstreifen und dem zweiten Schaumstoffstreifen lediglich an der inneren Seitenflanke des zweiten Schaumstoffstreifens nahe der Oberseite des zweiten Schaumstoffstreifens und an der inneren Seitenflanke des zweiten Schaumstoffstreifens nahe der Unterseite des zweiten Schaumstoffstreifens angeordnet sind. Auf diese Weise können die Haftstellen zwischen dem ersten Folienstreifen und dem ersten Schaumstoffstreifen und die Haftstellen zwischen dem ersten Folienstreifen und dem zweiten Schaumstoffstreifen gleichzeitig im selben Prozessschritt erzeugt werden.A particularly simple production of the sealing tape is obtained when the adhesion points between the first film strip and the second foam strip are arranged only on the inner side edge of the second foam strip near the top of the second foam strip and on the inner side edge of the second foam strip near the bottom of the second foam strip. In this way, the traps between the first film strip and the first foam strip and the traps between the first film strip and the second foam strip can be produced simultaneously in the same process step.
In einer weiteren Ausgestaltung kann der erste Folienstreifen vollflächig an der inneren Seitenflanke des zweiten Schaumstoffstreifens verhaftet sein, und die Haftstellen zwischen dem Folienstreifen und dem ersten Schaumstoffstreifen sind auf der Oberseite und auf der Unterseite des ersten Schaumstoffstreifens angeordnet.In a further embodiment, the first film strip may be fully adhered to the inner side edge of the second foam strip, and the detents between the film strip and the first foam strip are disposed on the top and bottom of the first foam strip.
Die Sperrschicht des Dichtbands weist in einer alternativen Ausgestaltung neben dem ersten Folienstreifen einen zweiten Folienstreifen auf, der mit dem zweiten Schaumstoffstreifen haftend verbunden ist. Der erste Folienstreifen ist dabei haftend mit dem zweiten Folienstreifen verbunden, und Haftstellen zwischen dem ersten Folienstreifen und dem zweiten Folienstreifen sind lediglich in einem Bereich nahe der Oberseite des ersten Schaumstoffstreifens und in einem Bereich nahe der Unterseite des ersten Schaumstoffstreifens angeordnet, während in einem Zwischenbereich zwischen den Haftstellen der erste Folienstreifen und der zweite Folienstreifen nicht miteinander verhaftet sind. Auf diese Weise können die Schaumstoffstreifen bereits in einem vorgeschalteten Produktionsschritt mit dem ersten Folienstreifen und dem zweiten Folienstreifen ausgestattet werden, und die Verhaftung der beiden ausgerüsteten Schaumstoffstreifen erfolgt lediglich durch Verhaftung der beiden Folienstreifen in einem späteren Verfahrensschritt.In an alternative embodiment, the barrier layer of the sealing tape has, in addition to the first film strip, a second film strip which is adhesively bonded to the second foam strip. The first film strip is adhesively bonded to the second film strip, and traps between the first film strip and the second film strip are disposed only in an area near the top of the first foam strip and in a region near the bottom of the first foam strip, while in an intermediate region between the traps of the first film strip and the second film strip are not arrested with each other. In this way, the foam strips can already be equipped in an upstream production step with the first film strip and the second film strip, and the arrest of the two equipped foam strips takes place only by arresting the two film strips in a later process step.
Vorzugsweise ist in dem Zwischenbereich zwischen den Haftstellen und somit zwischen dem ersten Folienstreifen und dem zweiten Folienstreifen die längslaufende Tasche ausgebildet.Preferably, in the intermediate region between the adhesion points and thus between the first film strip and the second film strip, the longitudinal pocket is formed.
In einer Ausführungsform weist die Sperrschicht einen längslaufenden schlauchförmigen Körper auf, der zumindest teilweise aus dem ersten Folienstreifen gebildet ist, wobei der schlauchförmige Körper in seinem Inneren den Hohlraum bildet und sowohl mit dem ersten Schaumstoffstreifen als auch mit dem zweiten Schaumstoffstreifen verhaftet ist. Dadurch können auch Dichtbänder großer Breite hergestellt werden, ohne dass der Schaumstoffverbrauch steigt. Zudem kann aufgrund der Ausdehnung des Hohlraums mehr Zusatzmaterial eingefügt werden.In one embodiment, the barrier layer has a longitudinal tubular body formed at least in part from the first film strip, the tubular body forming the cavity in its interior and being adhered to both the first foam strip and the second foam strip. As a result, it is also possible to produce sealing strips of great width without increasing the foam consumption. In addition, more filler material can be inserted due to the expansion of the cavity.
Um auch rieselfähige und flüssige Zusatzmaterialien besser aufnehmen zu können, ist es bevorzugt, wenn die Tasche oder der Hohlraum von allen sechs Seiten umschlossen ist.In order to be able to absorb free-flowing and liquid additional materials better, it is preferred if the pocket or the cavity is enclosed by all six sides.
Vorzugsweise weist die Sperrschicht eine Reißlasche auf, wobei durch Ziehen an der Reißlasche die Tasche oder der Hohlraum geöffnet werden kann. Auf diese Weise kann der Inhalt der Tasche oder des Hohlraums gezielt freigegeben oder aktiviert werden, beispielsweise erst nach Einbau des Dichtbands. Außerdem können auf diese Weise auch zwei reaktive Materialien gezielt miteinander in Verbindung gebracht werden, die zuvor getrennt in verschiedenen Kammern des Hohlraums oder der Tasche aufbewahrt wurden.Preferably, the barrier layer has a tear tab, which can be opened by pulling on the tear tab, the pocket or the cavity. In this way, the contents of the pocket or the cavity can be selectively released or activated, for example, only after installation of the sealing tape. In addition, in this way, two reactive materials can be selectively associated with each other, which were previously stored separately in different chambers of the cavity or the bag.
In allen Ausführungsformen ist es bevorzugt, wenn die Haftstellen als längslaufende Haftlinien ausgebildet sind. Dadurch ist eine durchgängige Verhaftung der beiden Schaumstoffstreifen miteinander gewährleistet, die noch dazu auf einfache Weise erzeugt werden kann.In all embodiments, it is preferred if the adhesion points are formed as longitudinal adhesive lines. As a result, a continuous arrest of the two foam strips is guaranteed to each other, which can also be generated in a simple manner.
Eine besonders einfache Herstellung des erfindungsgemäßen Dichtbands wird gewährleistet, wenn die Haftstellen durch Schmelzen und anschließendes Aushärten eines Verbindungsmaterials, insbesondere eines Klebers, gebildet sind.A particularly simple production of the sealing tape according to the invention is ensured if the traps are formed by melting and subsequent curing of a bonding material, in particular an adhesive.

Es kommen aber auch alle anderen Materialien in Frage, die geeignet sind, den Durchtritt von Luft oder die Dampfdiffusion durch das Dichtband 2 zu reduzieren. Eine vollständige Sperrung gegenüber einem Durchtritt von Luft oder gegenüber Dampfdiffusion ist möglich, aber nicht zwangsläufig notwendig. Es kann zweckmäßig sein, wenn der Folienstreifen 130 feuchtevariabel ist derart, dass er bei hoher Luftfeuchtigkeit diffusionsdichter ist als bei niedriger Luftfeuchtigkeit oder umgekehrt.The
Hinsichtlich der für den Folienstreifen 130 einsetzbaren Materialien wird beispielsweise auf
Im Beispielsfall der
Mit dem ersten Schaumstoffstreifen 114 ist der Folienstreifen 130 hingegen lediglich über bestimmte Haftstellen 132 verbunden. Die Haftstellen 132 befinden sich im dargestellten Beispielsfall der
Der obere Bereich 117, der Mittelbereich 121 und der untere Bereich 119 des ersten Schaumstoffstreifens 114 sind jeweils durch die punktierten Linien gekennzeichnet. Im entspannten Zustand des Dichtbands 2 beträgt die Höhe des Mittelbereichs 121 vorzugsweise mindestens 10 % der Höhe des gesamten Dichtbands, mehr bevorzugt mindestens 20 %, mehr bevorzugt mindestens 30 %, mehr bevorzugt mindestens 40 %, mehr bevorzugt mindestens 50 %, mehr bevorzugt mindestens 60 %. Der obere Bereich 117 und der untere Bereich 119 sind hingegen vorzugsweise weniger hoch und vorzugsweise im Wesentlichen von gleicher Höhe.The
Die Haftstellen 132 sind vorzugsweise als durchgängige Haftlinien in Längsrichtung des Dichtbands 2 ausgebildet, so dass zwischen den Haftstellen 132 eine Tasche 134 ausgebildet wird, die an mindestens vier Seiten vollständig von anderen Elementen des Dichtbands 2 umschlossen ist. Im dargestellten Beispielsfall bilden der Folienstreifen 130 und die innere Seitenflanke 122 des ersten Schaumstoffstreifens 114 (unterstützt durch die Haftstellen 132) die Begrenzungen der Tasche 134.The adhesion points 132 are preferably formed as continuous adhesive lines in the longitudinal direction of the sealing
Es sei erwähnt, dass die Tasche 134 in Querrichtung keine große Ausdehnung aufweist. Vielmehr wird die Tasche 134 in der Praxis lediglich als ein enger Schlitz zwischen den beiden Schaumstoffstreifen 114, 116 wahrzunehmen sein. Üblicherweise ist die Tasche 134 von vorne und hinten zugänglich, d.h. in den beiden Richtungen aus der Zeichenebene heraus und in die Zeichenebene hinein.It should be noted that the
Die Haftstellen 132 sind vorzugsweise durch Schmelzen und anschließendes Aushärten eines Klebers gebildet. Besonders bevorzugt ist es, wenn der Schmelzkleber als Bestandteil, beispielsweise in Schichtform, in den Folienstreifen 130 integriert ist und somit während des Herstellvorgangs lediglich durch Erhitzung und anschließendes Aushärten aktiviert wird. Auf diese Weise kann die Aufbringung eines zusätzlichen Klebematerials entfallen. Ebenfalls bevorzugt ist es, wenn der Folienstreifen 130 selbst thermoplastisch klebende Eigenschaften hat und somit das Material des Folienstreifens 130 durch Erhitzung angeschmolzen wird, sich klebend mit benachbarten Elementen verbindet und anschließend aushärtet.The
Besondere Bedeutung hat neben den Eigenschaften der Verringerung oder Verhinderung der Dampfdiffusion, dass jeder Folienstreifen 130 dauerelastisch ist, so dass er auch nach Lagerung des Dichtbands 2 im komprimierten Zustand bei der Rückstellung des Dichtbands 2 dauerhaft elastisch bleibt und im Einbauzustand des Dichtbands 2 in einer Fuge jederzeit dicht an den Fugenflanken anliegt.Special importance in addition to the properties of reducing or preventing vapor diffusion that each
An der Unterseite des Dichtbands 2 ist außerdem eine Klebeschicht 80 aufgebracht, die von einer Abziehfolie 81 bedeckt ist. Die Klebeschicht 80 dient der Anbringung des Dichtbands 2 am abzudichtenden Bauteil, wie später unter Bezugnahme auf

Bei der hier dargestellten Ausführungsform ist es vorteilhaft, wenn der Folienstreifen 130 bereits beidseits mit einer Schmelzkleberschicht ausgestattet ist, so dass bei Erhitzung und anschließendem Aushärten sämtliche Haftstellen 132 gleichzeitig gebildet werden.In the embodiment shown here, it is advantageous if the

Der zweite Folienstreifen 136 ist somit über Haftstellen 132 auf der einen Seite mit dem zweiten Schaumstoffstreifen 116 und auf der anderen Seite mit dem Folienstreifen 130 verhaftet.

Rieselfähige oder flüssige Materialien kommen lediglich dann in Frage, wenn die Tasche 134 zusätzlich in einer Richtung aus der Zeichenebene heraus und in die Zeichenebene hinein verschlossen ist, d.h. wenn die Tasche 134 von allen sechs Seiten umschlossen ist.Flowable or liquid materials are only suitable if the
Als Zusatzmaterial 140 kommen insbesondere in Frage Materialien zum Brandschutz (z.B. Blähgraphit, nicht brennbare Festkörper, CO2-Emitter etc.), Materialien zur Isolierung (z.B. PU-Schaum, Harze, Dichtstoffe etc.), Materialien zur Abdichtung gegen Feuchte (z.B. hydrophobe oder hydrophile Substanzen, bei Kontakt mit Wasser aufquellende Substanzen etc.), Materialien zur Schallisolierung, Materialien zur kontrollierten Belüftung (z.B. Katalysatoren etc.), Materialien für die Hygiene (z.B. Desinfektionsmittel etc.) und/oder Materialien zur Auslösung der Expansion des Dichtbands (z.B. Treibmittel, Wärmequellen etc.).As

Wenn die Haftstellen 132 wiederum als durchgängige, längslaufende Haftlinien ausgestaltet sind, wird in dem Zwischenbereich 138 zwischen den Haftstellen 132 und somit zwischen dem ersten Folienstreifen 130 und dem zweiten Folienstreifen 136 die längslaufende Tasche 134 ausgebildet, die wiederum an mindestens vier Seiten vollständig umschlossen ist.When the

Der schlauchförmige Körper 144 ist vorzugsweise aus demselben Material gebildet, das zuvor hinsichtlich des Folienstreifens 130 näher beschrieben wurde. Der Folienstreifen 130 bildet mit anderen Worten den schlauchförmigen Körper 144 oder ist zumindest Bestandteil davon. Der schlauchförmige Körper 144 kann aus einem einzelnen Folienstreifen 130 bestehen, kann aber auch aus verschiedenen aneinander laminierten Folienstreifen zusammengesetzt sein. Der schlauchförmige Körper 144 erstreckt sich in Querrichtung des Dichtbands 2 über vorzugsweise zwischen 5 mm und 100 mm.The

Die Reißlasche 146 kann an jedem beliebigen Punkt des schlauchförmigen Körpers 144 ansetzen. Es ist allerdings bevorzugt, wenn sie in einem Bereich nahe der Oberseite 118 des ersten Schaumstoffstreifens 114 bzw. nahe der Oberseite 124 des zweiten Schaumstoffstreifens 116 ansetzt.The
Die Reißlasche 146 kann auch bei jeder anderen Form des erfindungsgemäßen Dichtbands 2 verwendet werden, bei der eine an zumindest vier Seiten, vorzugsweise an sechs Seiten, vollständig umschlossene Tasche 34 oder ein an mindestens vier Seiten, vorzugsweise an sechs Seiten, vollständig umschlossener Hohlraum 150 vorliegt. Anstelle einer Reißlasche 146 kann auch ein Reißfaden oder ein anderes geeignetes Zugelement verwendet werden.The
Die Befüllung einer Tasche 134 kann vorzugsweise während des Herstellvorgangs des Dichtbands 2 erfolgen. Beispielsweise könnte die Befüllung in einem Zustand erfolgen, in dem die Tasche 134 noch an lediglich drei Seiten umschlossen ist, während sie an der vierten Seite noch offen ist. Von dieser vierten offenen Seite her könnte das Zusatzmaterial 140 in die Tasche 134 eingeführt werden, woraufhin die Tasche 134 an der vierten Seite, vorzugsweise mittels einer Haftstelle 132, verschlossen wird.The filling of a

Grundsätzlich können auch mehrere Schaumstoffstreifen 114, 116 nebeneinander angeordnet und auf erfindungsgemäße Art verbunden sein. In jedem Fall sollte eine Sperrschicht 30 mit mindestens einem Folienstreifen 130 zwischen jeweils zwei Schaumstoffstreifen 114, 116 angeordnet sein. Prinzipiell können Dichtbänder 2 beliebiger Ausprägung hergestellt werden, wobei sich Schaumstoffstreifen 114, 116 und Sperrschichten 30 vorzugsweise in Funktionsrichtung F abwechseln und vorzugsweise jeweils ein Schaumstoffstreifen 114, 116 an einem Rand des Dichtbands 2 angeordnet ist.In principle, a plurality of foam strips 114, 116 can also be arranged next to one another and connected in the manner according to the invention.

Für den Einbau ist das Dichtband 2 in der Regel zunächst von der Dichtbandrolle abzuwickeln und in Streifen beliebiger Länge zu schneiden. Üblicherweise wird die Länge der Dichtbandstreifen an die Außenkonturen eines abzudichtenden Fensterrahmens oder eines Türrahmens angepasst. Das Dichtband 2 wird dann vorzugsweise mittels der Klebeschicht 80 oder mittels anderer Klebeschichten, Klebebänder oder anderer geeigneter Mittel am Fensterrahmen 112 oder Türrahmen befestigt. Bei der Verwendung eines doppelseitigen Klebebandes als Klebeschicht 80 muss daher lediglich die Abziehfolie 81 entfernt werden, bevor das Dichtband 2 direkt am Fensterrahmen 112 angebracht werden kann.For installation, the sealing
