Abstract

The invention relates to a sealing strip (1), for sealing a gap between brickwork and a window frame. Said strip has a support strip (13) with two longitudinal edges (2, 3), an adhesive mass (4, 5), e.g. in the form of a self-adhesive strip and/or a butyl mass, which is covered by a protective layer (6, 7) that can be removed for use, being allocated and applied to both longitudinal edges (2, 3). The aim of the invention is to provide a sealing strip for use in construction, the adhesive options of which are endlessly versatile. To achieve this, by protruding beyond the longitudinal edge (3), each adhesive mass (5) can also be used to bond the sealing strip (1) on the opposite side.

Description

The invention relates firstly to a sealing tape, for example, between a masonry and a window frame, with a two longitudinal edges having carrier tape, wherein associated two longitudinal edges of one of a removable for use protective layer adhesive composition is applied, for example in the form of a self-adhesive strip and / or in shape a butyl mass. Furthermore, the invention relates to a method for producing a sealing strip and the use of a sealing strip.

Such sealing tapes have already become known in a variety of configurations. It is for example on the DE 298 07 620 U1 or the EP 1 433 917 A1 directed. This sealing tapes are usually formed on the basis of a nonwoven material, sometimes with a metallic layer or plastic layer to achieve defined water vapor permeability or water vapor tightness. They are typically glued in a window opening between the window frame and the masonry. Here, the bonding is often made on the masonry by means of a butyl layer and the window frame by means of a self-adhesive strip.

The DE 201 21 253 U1 describes a sealing tape of several layers, wherein provided at each longitudinal edge of an adhesive is. The adhesives are mounted on opposite sides of the sealing tape so that an adhesive bondability with another component is provided on each side of the sealing tape.

The DE 10 2005 039 157 A1 describes a sealing tape with connection profile.

Depending on the structural conditions, it may be desirable that the bond is not made in each case, so for example with the masonry and the window frame, on the same side of the sealing strip, but on different sides of the sealing strip.

The invention is based on the illustrated prior art, the task of specifying a sealing strip for use in the construction sector, which is as variable as possible with respect to the bond.

The object is solved by the independent claims 1, 2, 13 and 16, 17.

A possible solution to the problem is given by the subject matter of claim 1, wherein in this case it is aimed that an adhesive mass is partially arranged in overlapping to the carrier tape and partially protruding beyond the longitudinal edge. As a result of the edge overhang, this adhesive composition, since it is adhesive on its two flat sides, can also be used with regard to adhesive formation of the sealing strip on the opposite side associated with the same longitudinal edge. The adhesive mass engages over the associated longitudinal edge of the carrier tape. It can make a rollover or a projection. The supernatant is understood to be transverse to the longitudinal direction of the longitudinal edge, which is assigned to the adhesive mass. This overlapped or protruding width range of the adhesive is then also in relation to the opposite side of the sealing tape haftaktiv, so can be used as well on the opposite side to the arrest. In the case of the rollover, an adhesion of the adhesive mass against itself and / or an arrest can also be realized on the opposite side of the carrier tape. Due to the two-sided adhesion of the adhesive itself is in any case an adhesion of the sealing strip - assigned to this longitudinal edge - given on both flat sides.

In general, it is preferred that the sealing strip associated with a longitudinal edge has only one bondability by means of a butyl adhesive strip or at least one adhesive strip of adhesive to a certain extent or paste-like adhesive and the other longitudinal edge associated with self-adhesive strips.

Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 1 and / or other feature complexes. But they can also be in an assignment to only individual features of claim 1 or the respective further claim or further feature complex or each independently of importance.

In the solution of the problem by the subject matter of claim 2, two adhesive compositions are provided on both sides of the carrier tape, assigned the same longitudinal edge. These adhesive compositions are arranged opposite each other in a cross section with respect to the carrier tape. However, you do not necessarily need to be arranged congruent opposite, as also explained below. In particular, this embodiment need not be combined with the measure that a (relevant) projection is present over the longitudinal edge.

In this context, however, it may also be preferred that both adhesive compositions are arranged protruding beyond the longitudinal edge.

Thus, it is also preferred that both adhesive compositions are adhered over a part of their surface against itself or against the other adhesive mass. The former is particularly possible even if only one adhesive is provided. In the case of two adhesive masses, the above-described adhesiveness of the sealing strip to the two flat sides with respect to one of the flat sides is (also) used to achieve arrest with a further adhesive mass, which can then (only) provide the adhesion to a component, for example.

Further preferred in this context is that the mutual adhesion of the adhesive masses, even in the case of the arrest of only one adhesive mass against itself, is given only in the region projecting beyond the longitudinal edge.

The fact that, in the case of two adhesive compositions, these are arranged opposite each other with respect to the carrier tape, in a cross section, but are subsequently arrested against each other according to an embodiment in their laterally beyond the longitudinal edge region, not only is an arrest with each of the two flat sides given the sealing strip, but also an arrest of the sealing bands with each other. In the event that the arrest with one of the flat sides of the sealing strip is reduced by certain influences, it can nevertheless not come to a complete separation of an adhesive layer of the sealing strip, since they then at least by means of the arrest with the further adhesive mass or possibly through the Arrest with himself and the thus fold-like arrangement, is still supported by the remaining arrest on the opposite side in the required manner.

It is also preferable that at least one of them is the same Longitudinal edge associated adhesive masses, possibly also only one, over the longitudinal edge outstanding provided adhesive mass used to stabilize a longitudinal folding of the sealing strip.

With regard to the above-mentioned configuration of only one adhesive mass which is adhered to itself in the region projecting beyond the longitudinal edge, a preferred arrangement is given by the fact that this adhesive composition is arrested against itself in one partial region and with opposite sides in further partial regions the sealing edge.

Furthermore, it is also preferred that the adhesive mass forming the supernatant is covered on both sides by a respective protective layer. The protective layer serves to cover the adhesive until it is used. Specifically, this may be a non-adhesive to the adhesive mass, but merely peelable adhesive cooperating plastic film. For example, it may also be a siliconized paper. In the event that only one adhesive is provided, on both sides of this adhesive, once on the width of the adhesive strip on the side of the sealing strip on which the adhesive strip is originally applied and on the other concerning the width, the adhesive on the opposite side is effective, applied a protective layer, which ensures the usual ease of use of the sealing strip. In the state of use, d. H. when installed, then a protective layer can remain on the sealing strip.

The same principle arises in the case of two adhesive masses. Here, a cover is arranged on each of the adhesive masses, which are arranged opposite one another with respect to the sealing strip in a cross section. In general, these covers will then be nationwide, without displacement to each other, arranged. The latter is also possible.

In the case of only one adhesive, it is possible, as already mentioned, for example by simply folding over a longitudinal edge of the carrier tape, preferably also here with overhang over the longitudinal edge of the carrier tape of the sealing strip, that the adhesive active areas of both sides serving for arresting adhesives are the same surface , so are not offset from each other. Equally, however, it is also possible that there is only an overlap in a subarea. In this way, on the other hand regularly, with the exception of a half division, given that the available adhesive width of the adhesive composition is different depending on the side of the sealing strip. Because in this case acts on the side of the carrier tape on which the adhesive composition is not appropriate, as an adhesive surface only over the peripheral edge projecting or unfolded section. In general, it will be provided that the adhesive surface (whose width) is small on the side on which the adhesive is not applied.

In the case of two adhesive masses, which are each assigned to the same longitudinal edge on one side of the sealing strip, on the other hand is generally preferred that they are arranged in a cross-sectional view aligned or in overlap, so in each case offer practically the same adhesive surface. They are correspondingly congruent in one projection. Furthermore, it is also preferred that the (one) adhesive mass or one of the two adhesive masses stabilizes an infill of the sealing tape. This is a continuous over the length of the sealing strip folding, so a longitudinal folding. It is further preferred that this infill is at least partially in overlap with the adhesive mass. Thus, the Einfaltelung is also stabilized by the adhesive.

The fact that a sealing tape as described herein offers a possibility of arresting on both sides, at least with respect to a longitudinal edge of the sealing tape, can not be used only to the same sealing tape differently, ie on the front or back, associated with a longitudinal edge to glue. Rather, this can also be used to ensure that the adhesive side or adhesive material not used in each case for bonding to the component is also used, by means of the sealing tape, for a further object, such as a strip, for example a plaster strip, with a component, such as a window frame to stick.

Especially in this case, the arrangement of the two same longitudinal edge associated adhesive masses can be chosen so that no overlap between the adhesive is given, but also an overlap or even as already addressed aligned arrangement (concerning a cross-sectional view) is a preferred embodiment.

The mutual adhesion of the adhesive masses or the adhesion of an adhesive mass to itself is preferably given only in the region projecting beyond the longitudinal edge.

In the case of the sealing strip, an adhesive mass can be arrested in each case in a partial area with opposite sides of the sealing strip.

In a sealing tape according to the invention, the adhesive width of an adhesive mass or the adhesive masses may be different on the opposite sides of the sealing strip.

The adhesive areas of each arranged on one side of the sealing strip, the same longitudinal edge associated adhesive masses may overlap each other or may be congruent in a projection.

With regard to a component, explained using the example of a plaster strip, first the sealing tape with the first flat side with the component, such as the window profile can be adhesively bonded and further, for example, only after completion of this Anklebevorganges, the plaster molding on the component adhesive bond facing away from the second flat side Sealing tape to be applied adhesive technology. It does not require a possibly cumbersome simultaneous handling of sealing tape and plaster molding. In addition, due to the covering, at least overlapping adhesive bonding flat sides, the adhesive area available for bonding to the component is reduced compared to a customary juxtaposition and adhesion of sealing tape and plaster molding on the component, so further preferably minimized to the adhesive to be bonded Support surface of plasterboard. In the installation situation, according to the proposed solution, the sealing strip is adhesively bonded between the plastering strip and the component, wherein the plastering strip is in turn adhesively bonded to the component via the sealing strip.

In this case, the actual sealing strip, for example in the form of a nonwoven / film composite, does not necessarily have to be held directly between the plastering strip and the component to form double-sided adhesive bonds. Rather, the adhesive joints on the two opposite flat sides offering portion of the sealing strip may also be a permanently attached to the sealing tape adhesion strip or the like. The adhesive bonds on the two opposite flat sides must, as already mentioned in principle, not necessarily be completely overlapping. A (mere) overlap of these adhesive surfaces is possible. In this regard, it proves to be advantageous if, at least in one projection onto the contact surface of the plastering strip, the opposite adhesive surfaces lie in full coverage.

In the case of the component, the adhesive connection between the plastering strip and the sealing strip can be made to overlap the adhesive bond between the sealing strip and the component.

In the component, the self-adhesive strips of both flat sides can be formed independently of each other.

In the case of the component, both the sealing strip and the plastering strip can be connected to the component by the same adhesive-effecting self-adhesive strips on both sides.

It may be formed without an adhesive or a self-adhesive strip in the component, the plaster molding.

Further features of the invention are explained below, also in the description of the figures, often in their preferred assignment to the object of the above-mentioned feature complex. But they can also be in an assignment to only individual features of this complex or each independently of importance.

A possible embodiment is also given by only one self-adhesive strip, which is provided a protrusion or flashover along the longitudinal edge of the sealing strip or this encompassing forming, so on, for example in the manner of a double-sided adhesive tape. Thus, it is provided that both the sealing strip and the plastering strip are connected to the component only by a self-adhesive strip, in particular the same adhesive on both sides. This is in a preferred embodiment transversely to the longitudinal extent of the sealing strip and the strip beyond the longitudinal edge of the sealing strip addition, which protruding portion of the double-adhesive self-adhesive strip on the one hand can be used to adhere to the component and opposite to the adhesion of the plaster. On the component side facing flat side of the self-adhesive strip, the sealing strip is also connected. Accordingly, in the installed state component and sealing tape can be connected via the self-adhesive strip in juxtaposition, further wherein the self-adhesive strip on both sides of an adhesive forms an extension or a connection region of the sealing strip and thus a part thereof.

In the same way, however, the already described embodiment may be useful, in which on both flat sides of the sealing strip, associated with the longitudinal edge, an adhesive strip, in particular self-adhesive strip is provided, and these two self-adhesive strip with a projection over the longitudinal edge (in the width direction of the sealing strip ) are provided and are arrested directly against each other in the area of this supernatant.

Advantageously, it is provided that the plastering strip is formed even without self-adhesive strip. The adhesive surface is offered by the sealing tape.

Incidentally, in this context, all other variants of the sealing strip, which are not additionally discussed in detail here, which are discussed above, can be provided.

The sealing strip according to the invention can be used for attaching a strip, in particular plaster strip on a component, such as a window profile, wherein a sealing strip is further attached to the component.

In order to design such a use, in particular in terms of use, it is recommended that the strip be attached to the component by means of the sealing strip. The strip is correspondingly not attached directly to the component, which in particular brings a separate attachment for the bar with it, so on in particular a self-adhesive layer on the bar. The sealing strip itself preferably has means for fixing the strip, wherein the sealing strip is correspondingly carrier of the strip for placement on the component. Furthermore, the handling is simplified as a result, so that preferably in two successive steps sealing strip and plaster strip can be arranged on the component. Basically, there is also the option of first fixing the strip on the sealing strip and then together on the component.

In the method of attaching an article, preferably, the article is adhesively bonded to the component by means of the sealing tape.

Further provided is a method for attaching an article such as a strip, in particular a plaster strip, to a component, such as a window profile, wherein a sealing strip is further attached to the component, wherein the strip is attached to the component by means of the sealing strip.

For use, the above may also be mentioned in relation to Sealing tape alone described various embodiments of the sealing strip (each) are used.

The invention further relates to a method for producing a sealing strip, for example, between a masonry and a window frame, wherein the sealing strip has two longitudinal edges and at both longitudinal edges of a covered by a protective layer for use protective layer adhesive is applied, for example in the form of a self-adhesive strip and or in the form of a butyl compound.

For general technology of these sealing tapes reference is made to the already made at the beginning.

In order to advantageously design such a method while achieving a sealing tape that is favorable in terms of its attachment possibilities, the invention proposes that the adhesive mass is applied over this longitudinal edge in any case with respect to a longitudinal edge in the form of a contiguous adhesive strip and at least the supernatant by one from the opposite side of the Sealing tape tapered protective layer is covered.

The infiltration of the adhesive strip takes place in a contiguous form, wherein this contiguous shape can be achieved by the consistency of the adhesive strip itself, but also by applying and resting on or in the required manner adhering to the protective layer, which thus can run with the same. Although it is preferred that the adhesive mass forming the supernatant has a consistency which corresponds to a self-stabilized coherent shape, nevertheless it is already combined with the protective layer when it is being used.

The supernatant, which may also be a remaining supernatant, such as when it comes to an Umfaltelung or shrinkage of the adhesive composition, is also covered by a tapered from the opposite side of the sealing strip - further - protective layer. With regard to the configuration of such a protective layer has already been stated above, to which reference is made.

But it can also be provided, based on the case of an umfaltelung that the tapered adhesive mass, ie in particular in a known manner double-sided adhesive Selbstkelebstreifen, one side, on the inlet side, already covered with two protective layers, so two arranged in the sense of a longitudinal separation side by side Protective layers has. With the help of one of the protective layers, suitably the outer edge protective layer, then procedurally favorable folding or folding can be made.

With regard to additional or alternative features in connection with the production, the same applies to the demanding allocation as mentioned above with regard to the product-related features.

According to the method, it is further preferred that the application of the adhesive mass on the one side is carried out immediately with the covering protective layer is, while on the other hand, on which the adhesion activity is given in terms of the supernatant, the protective layer is applied to the already resting on the carrier tape - and accessible from this other side - part of the adhesive strip. In the case of two adhesive compositions, each of which - applied at the same time or one after the other in a continuous process - on each side, both can be applied immediately with covering protective layer. In this case, the width of the protective layers or the orientation of the protective layers in the application can be chosen so that the protective layers are as such in overlap with each other, with virtually no offset, or in the projection have a supernatant to each other. In the one protective layer is then usually account for a greater proportion of the width of the not provided with adhesive material portion of the carrier tape than the other protective layer, wherein such a longitudinal portion of the protective layer, which is not in overlap to the adhesive layer, anyway for simplified deduction of Protective layer is advantageous.

It is also preferred that prior to application of the adhesive on a longitudinal edge, which is assigned to this adhesive, an infill of the carrier tape is made and this Einfaltelung is fixed by means of the adhesive. In a continuous process, this can be achieved particularly favorably if the filling is carried out locally close to or even immediately before application of the adhesive, and then the adhesive material then running can readily achieve the fixation of the infill.

It is also preferred that the adhesives are applied from different sides of the sealing strip.

Shown and described, first with reference to the Fig. 1 to 3 , a sealing tape 1, which serves to seal between a masonry and a window frame on a building. The installation situation itself is not shown here and explained. Reference is made in this respect to the documents mentioned above.

The sealing tape 1 has a carrier tape 13, which consists in the embodiment of a nonwoven / film composite. The sealing tape 1 is also preferably with the exception of the adhesive strip only from this carrier tape 13. This carrier tape 13 has two longitudinal edges 2, 3, wherein associated with the longitudinal edge 2 on the first side ( Fig. 1 ) An adhesive 4 is applied. the Associated longitudinal edge 3 is on this page an adhesive mass 5 effective, but on the opposite side (see Fig. 2 and the following comments on this) of the carrier tape 13 is applied.

In the exemplary embodiment, the adhesive mass 4 is a butyl material, while the adhesive mass 5 is a self-adhesive layer, which may be formed, for example, on the basis of an acrylate adhesive.

The adhesive mass 4 is covered with a - in the embodiment opaque - protective layer 6 and the adhesive mass 5 on the in Fig. 1 visible side with a - transparent in the embodiment - protective layer. 7

Assigned to the longitudinal edge 3 in the embodiment continues in the sealing strip 1 Einfaltelung 12 made of the in Fig. 1 the longitudinal edge 2 associated longitudinal edge 8 is visible. The longitudinal edge 8 is arranged facing the opposite longitudinal edge 2, while the longitudinal edge 10 of the folding 12 is associated with the longitudinal edge 3 and a peripheral edge 11 of the sealing strip 1. The peripheral edge 11 in this case forms the edge-outermost edge of the sealing strip 1.

The sealing strip 1 is very long compared to its width. For example, it may have lengths of 10 to 40 m at widths of 50 to 500 mm.

In the embodiment is on the zu Fig. 1 opposite side of the sealing strip 1, in Fig. 2 is shown, the longitudinal edge 2 assigned no adhesive applied. But probably associated with the longitudinal edge 3. Namely, the already mentioned adhesive mass 5.

Next on this second side or back another - here also transparently selected - protective layer 9 is applied, which also covers the longitudinal edge 10 of the folding, which is associated with the longitudinal edge 3, in the embodiment with.

As can be seen in particular Fig. 3 shows, the peripheral edge 11 of the sealing strip 1 is formed only by the adhesive mass 5 and the protective layers 7 and 9 respectively.

The adhesive mass 5, which is applied in the form of a coherent adhesive layer, projects beyond the longitudinal edge 3 of the carrier strip 13, namely by the projection U. The adhesive 5 or optionally the marginal edges of the protective layers 7 and / or 9 form the marginal edge 11 of the sealing strip 1.

The described arrangement of the adhesive 5 can both, based on Fig. 3 , an arrest with respect to the lower side of the sealing strip 1 are made there, when removing the cover layer 9, or with respect to the upper side there, after removing the cover layer. 7

While on the in Fig. 3 upper side of the adhesive width of the adhesive mass 5 is limited to the dimension U, the total width B of the adhesive mass 5 is available for arrest on the opposite side.

The Einfaltelung 12 is also stabilized by the adhesive mass 5, which adhesive mass 5 extends in terms of their width B over both a portion (B minus U minus b), which is associated with the unfolded width of the sealing strip 1, as well as a section b, which folded width of the carrier tape 13 is assigned.

The protective layer 9 has a width corresponding to the width B of the adhesive mass 5, while the protective layer 7 has a width which exceeds both the adhesive width U as well as, preferably in the embodiment, the width B of the adhesive 5.

With reference to Fig. 4 the production of the sealing strip 1 is explained. A carrier tape 13 is moved horizontally, wherein in the illustrated section of the production is assumed that the adhesive material 4 (preferably also already with protective layer) assigned to the longitudinal edge 2 is applied. With respect to the longitudinal edge 3, a supply roll 14 is arranged above the carrier strip 13, from which a combination of the adhesive mass 5 with the protective layer 9 tapers. This feed is realized in the direction of production after passing through a first hold-down and / or transport roller 19. This combination proceeds with the moving carrier tape 13 and is pulled along by the carrier tape 13 due to the arrest of the located on the bottom of this combination adhesive material in the form of adhesive. About a here only indicated roller 17 solidification is achieved. Beforehand, what has not been shown here in detail, the Einfaltelung 12 has already been made in the carrier tape 13. Next runs below from the bottom of the protective layer 7, from a supply roll 15. This is pressed with a roller 16. By means of the protective layer 7, the supernatant U is covered, as in detail Fig. 3 is also apparent.

In Fig. 5 another embodiment is shown. This relates to a sealing tape 1 with a carrier tape 13, which end, assigned to the longitudinal edge 3 on both sides with an upper and a lower self-adhesive strip formed adhesive mass 5, 5 'is provided. These self-adhesive layers 5, 5 'are arranged overlapping in the illustrated embodiment, but may also overlap to one or both longitudinal edge sides. Both self-adhesive layers 5, 5 'are covered before application with a, in particular transparent protective layer 7 or 9.

The underside (first flat side) associated self-adhesive layer 5 is used for adhesive adhesion of the sealing strip or the carrier tape 13 to a component 20, here a window profile. For adhesive fixing of the self-adhesive strip 5 is exposed by deduction of the protective film 9. In particular, after adhesion of the carrier tape 13 to the component 20, the self-adhesive layer 5 'lying opposite the component adhesive joint can be exposed by stripping off the further protective film 7 for bonding a strip, in this case a plastering strip 21.

Alternatively, the self-adhesive layer opposite self-adhesive layer opposite adhesive layer 5 can be freed from the film 7, the arrangement of the plaster strip 21, after which the plaster strip 21 together with the carrier tape 13 or sealing tape 1 for arrangement on the opposite self-adhesive layer 5 on the component 20th be arrested.

The two self-adhesive layers 5, 5 'are, as shown, formed independently of each other. Preferably, in this regard, a solution in which only a self-adhesive layer 5, the longitudinal edge edge 3 rollover, ie folded around the longitudinal edge edge 3 (back), is arranged to form a double-sided adhesive layer. It would then relate to FIG. 5 the dashed course additionally result. A relevant edge projection would not be given, but possible (in this case then suitably with the self-adhesive layer against itself).

A further preferred embodiment is in the Fig. 6 and 7 shown. Here, a double-sided adhesive-effect self-adhesive strip 5 is provided, both for adhesive adhesion of the sealing strip 1 and carrier tape 13 to the Component 20 as well as adhesive bonding of a bar, in particular plaster bar 21 on the component 20 is used. This self-adhesive layer 5, which acts on both sides, acts on the longitudinal edge 3 of the carrier strip 13, thus in the exemplary embodiment illustrated by the half width dimension measured transversely to the longitudinal extent of the sealing strip 1. Accordingly, the self-adhesive strip acts on the underside (in FIG. 7 it is according to the illustration, the top) over half the width dimension adhesive bonding with the carrier tape 13, wherein in a state of delivery shown here, over the longitudinal edge 3 protruding adhesive portion of the protective layer 9 is covered.

The opposite adhesive surface of the self-adhesive layer 5 is covered over the entire width of the associated protective layer 7, is accordingly after deduction of this protective layer 7 over the entire area available.

The self-adhesive strip 5 represents in the context of the invention as shown in FIG Fig. 6 an extension or a part of the sealing strip 1 and the carrier tape 13 is.

The sealing tape 1 is shown in FIG Fig. 7 at the edge of the component, here glued to the window profile. After deduction of the component adhesive bond opposite protective layer 7, the sealing tape 1 and the self-adhesive layer 5 is used for further adhesive arrangement of a bar, here a plaster bar 21. The gluing of the plaster bar 21 takes place in a covering the surface of the component adhesive joint layer.

In a further embodiment, for arranging a plastering strip 21 on a component 20 according to the embodiment in Fig. 7 Also, a sealing strip 1 according to the embodiment in Fig. 3 come into application, in which case the adhesion of the sealing strip 1 to the component 20 over the entire width B of the self-adhesive layer 5 takes place and the arrangement of the plastering strip in this case 21 in the adhesive area of the upper side of the self-adhesive layer 5, which projects beyond the longitudinal edge 3, according to the in Fig. 3 designated measure U.

Next is related to the FIGS. 8 to 11 a sealing tape 1 further embodiments described, which serves for sealing between a masonry and a window frame on a building.

The sealing tape 1 has a carrier tape 13, which consists in the embodiment of a nonwoven / film composite. This carrier tape 13 has two longitudinal edges 2, 3, wherein associated with the longitudinal edge 2 on the first side ( Fig. 8 ) An adhesive 4 is applied. Associated with the longitudinal edge 3 is an adhesive mass 5 applied on this side and on the opposite side (see Fig. 9 and the following comments on this) of the carrier tape 13, a further adhesive mass 18 is applied.

In the exemplary embodiment, the adhesive mass 4 is a butyl material, while the adhesive masses 5, 18 are each a self-adhesive layer, which may be formed, for example, on the basis of an acrylate adhesive.

The adhesive mass 4 is covered with a - in the embodiment opaque - protective layer 6 and the adhesive mass 5 on the in Fig. 8 visible side with a - transparent in the embodiment - protective layer. 7

Assigned to the longitudinal edge 3 is in the embodiment further in the sealing strip 1 Einfaltelung 12 (see Fig. 12 ) made by the in Fig. 8 the longitudinal edge 2 associated longitudinal edge 8 is visible. It is therefore evident to a folding over the length of the sealing strip 1 extending folding 12. The longitudinal edge 8 is facing the opposite longitudinal edge 2 arranged facing, while the longitudinal edge edge 10 of Fold 12 is associated with the longitudinal edge 3 and the peripheral edge 11 of the sealing strip 1.

The sealing strip 1 is very long compared to its width. For example, it may have lengths of 10 to 40 m at widths of 50 to 500 mm.

In the embodiment is on the zu Fig. 8 opposite side of the sealing strip 1, in Fig. 9 is shown, the longitudinal edge 2 assigned no adhesive applied. But probably associated with the longitudinal edge 3. Namely, the already mentioned adhesive mass 18.

Next on this second side or back another - here also transparently selected - protective layer 9 is applied, which also covers the longitudinal edge 10 of the folding, which is associated with the longitudinal edge 3, in the embodiment with.

Both adhesive masses 5,18 are preferred, as can be seen from the illustrations, on the longitudinal edge 3 is not over.

In the embodiment of the 10 and 11 , or the cross-sectional view according to Fig. 13 is given a same structure as in the embodiment of 8 and 9 , or the cross-sectional view according to Fig. 12 but without the folding 12. The adhesive masses 5, 18 are arranged overlapping each other with respect to the carrier tape 13. Therefore, also with respect to the longitudinal edge 3 is a basically the same representation in the Fig. 10 and 18.

In reference to Fig. 12 is to be supplemented:

An infill 12 is also stabilized by the adhesive mass 5, which Adhesive compound 5 extends in terms of their width B both over a distance (B - b), which is associated with the unfolded width of the sealing strip 1, also over a portion b, which is associated with the folded width of the carrier tape 13.

The protective layer 9 has a width corresponding to the width B of the adhesive 5, while the protective layer 7 has a width which is selected to be larger in the embodiment, namely in the cross-sectional view according to FIG Fig. 12 the width of the protective layer 9 inwardly, that is assigned to the opposite peripheral edge 2, outstanding.

The application of the sealing strip according to the embodiment of 10 and 11 or 13 in association with the component (complementary or alternative to the usual application as a sealing strip, see introductory statements), here a window profile 20, is already with reference to Fig. 5 explained. Here, the self-adhesive strip 5 is exposed by peeling off the protective film 9 for adhesive attachment; In particular, after adhesion of the carrier tape 13 to the component 20, the self-adhesive layer 18 opposite the component adhesive joint can be exposed by stripping the further protective film 7 for the adhesive arrangement of an article such as a strip, here a plaster strip 21.

Alternatively, the self-adhesive layer opposite self-adhesive layer 18 serving the component adhesive bond can be freed from the film 7, to arrange the plaster strip 21, after which the plaster strip 21 together with the carrier tape 13 or sealing tape 1 for placement on the opposite self-adhesive layer 5 on the component 20th be arrested.

The two self-adhesive layers 5, 18 are, as shown, formed independently of each other. However, it is also possible a solution in which only a self-adhesive layer 5, the longitudinal edge edge 3 is arranged protruding to form a double-sided adhesive layer. This is already fundamentally related to the FIGS. 5, 6 and 7 explained. Fig. 14 shows a variant.

Usually, although not necessarily, the training is provided on the opposite side, as they relate to the FIGS. 8 to 11 is explained, that is about with the Buthylklebestreifen 4. In the embodiment of the Fig. 6 the double-sided adhesive self-adhesive layer 5 protrudes beyond the longitudinal edge of a carrier tape 13, so in the illustrated embodiment by the width dimension of the self-adhesive layer 5 measured transversely to the longitudinal extent of the sealing tape 1. The self-adhesive strip acts on the underside over half the width dimension adhesive bonding with the carrier tape 13 while the over the longitudinal edge 3 protruding adhesive portion is covered by the protective film 9.

The opposite adhesive surface of the self-adhesive layer 5 is covered over the entire width of the associated protective layer 7, is accordingly after deduction of this protective layer 7 completely available.

The self-adhesive strip 5 represents in the context of the invention as shown in FIG Fig. 6 an extension or a part of the sealing tape 1 and the carrier tape 13 (in both directions).

The sealing tape 1 according to Fig. 6 respectively. Fig. 14 becomes according to the representation in Fig. 7 edge of the component, here the window profile, for example, glued. After deduction of the component adhesive bond opposite protective layer 7, the sealing tape 1 and the self-adhesive layer 5 is used for further adhesive arrangement of an object such as a bar, here a plaster bar 21. The gluing of the plaster bar 21 takes place in a covering the surface of the component adhesive connection system. Alternatively, that too Sealing tape 13 be so far in overlap to the component 20 to be glued that the self-adhesive strip 5 is over the entire width in coverage to the component. Accordingly, the sealing strip 21 can be wider. In particular, the sealing strip 21 can be broad-adapted to the width of the self-adhesive strip 5.

Related to the FIGS. 15 and 16 Again, further embodiments of the sealing strip 1 are shown.

Only the cross sections are shown here. The views according to Fig. 1 and 2 or the composite with a bar, as appropriate Fig. 5 or Fig. 7 , results in a comparable way.

In the embodiment of the Fig. 15 is important that with respect to the sealing strip 13 opposite two adhesive masses 5, 18 are provided. The adhesive masses 5.18 consist in the embodiment of self-adhesive strips. They have accordingly on both broadsides and usually on their narrow sides an adhesive ability.

Both adhesive masses 5, 18 are also practically congruent, so aligned - in relation to the cross-sectional view - arranged one above the other.

In such a way with respect to the longitudinal edge 3 that a portion T1 is located on the sealing strip 13 and a portion of T2 extends freely projecting to the longitudinal edge 3. In this case, T2 can be approximately equal to T1. In the illustrated embodiment, T2 is smaller than T1. T2 corresponds to about 20 to 45% of T1, whereby also any averages, ie 21%, 44%, etc. are also included in the disclosure.

This with a total width (T1 + T2) of such an adhesive strip - self-adhesive strip - in the range of 1 to 5 cm, in special applications (such as wide bar) also wider, more preferably from 2 to 4 cm, in which case, starting from the largest range, all intermediate values, at least in millimeters, are included in the revelation.

Although in Fig. 16 two individual self-adhesive strips 5, 18 are shown, which are just in the supernatant region, T2, directly against each other arrested, so it is also possible that this is only a self-adhesive strip, then in the free forehead, see x, a refolding would be given ( see also Fig. 5 ).

The embodiment of the Fig. 15 is different from the one of Fig. 16 by Einfaltelung 12. It is basically a same Einfaltelung, as it was already further forward with respect to the Fig. 3 and 12 has been explained. It is essential that the adhesive mass 5 is arranged in overlap also to the longitudinal edge 10 created by the folding. Characterized in that the adhesive mass 5 is adhesively bonded to the carrier tape 13, seen from the longitudinal edge 2 from already before the peripheral edge 10 and further simultaneously adhering to the beyond the peripheral edge 10 in the width direction of the carrier tape 13 further extending portion of the carrier tape, the Finally, the longitudinal edge 3 forms, a certain initial stabilization of this Einfaltelung is given. After installation of the sealing strip can then occur during certain component movements unfolding, as far as a latitude stock is created.

In the embodiment of Fig. 15 is further seen that the adhesive compositions 5 and 18 are provided with respect to the cross-sectional view with different width. The adhesive mass 5 has a significantly greater width than the adhesive mass 18th

This also means that the area T1 is different in the subject of this embodiment. This area is therefore designated T1 at the top and T1 * at the bottom. T1 * is larger than T1. T1 * may be 5% or more larger than T1. Especially in the range of 5-50%.

Incidentally, in the embodiments of the FIGS. 15 and 16 the protective layers 7 and 9 can be seen.
