Description

The present invention relates to a plastering strip and a building transition with a plastering strip.

Common plastering strips that are used in a transition between a thermal insulation of a building and a window or door frame often include a sealing tape that expands over time and thus seals the transition.

In practice, the problem often arises that such a sealing tape shrinks and that the seal is therefore shortened, in particular at the end regions of the plastering strip.

It is therefore an object of the present invention to provide a plastering strip with which a reliable sealing effect is achieved over the entire length.

The EP 1 793 061 A2 discloses a plaster end strip for a layer of plaster on thermal insulation which has the following features: (a) a base region that supports an expansion strip; (b) a confinement area which, in the confined state, prevents the expansion strip from expanding and which can be brought into a release state releasing the expansion strip for expansion by a user of the plaster end strip; (c) wherein the plaster end strip is designed to be fixed in position in the installed state by connection to the thermal insulation and, in the released state of the confined area, to allow the expansion strip to expand in the direction away from the thermal insulation and onto an opposing surface.

From the WO2002 / 020247 a method and a device for producing plastic profiles are known. The plastic profile consists of at least one hard profile strand, for example made of hard PVC, and at least one soft profile strand, for example made of soft PVC. Both profile strands are produced simultaneously by separate extrusion nozzles and cooled in a cooling device. The soft profile strand is fed directly from the extruder into a cooling bath, in which it is completely cooled. The hard profile strand and the soft profile strand are then connected under pressure.

The DE 34 05 512 A1 shows a method and a device for the positive pressing of sealing profiles into frame profiles. In the method for the positive pressing of sealing profiles with free-standing sealing lip made of elastomeric materials into undercut longitudinal grooves of frame profiles by means of a pressure roller, at least one pressure roller is used that is essentially complementary to the outwardly facing part of the profile cross-section of the sealing profile. This is driven at a peripheral speed that is greater than the translation speed at which the axis of the pressure roller moves relatively parallel to the longitudinal axis of the frame profile. The direction of rotation of the pressure roller is selected in such a way that the partial length of the sealing profile, which is already positively locked in the frame profile, is subjected to compression.

This object is achieved by the subject matter of the independent patent claims. Advantageous further developments result from the dependent claims.

It is emphasized here that the invention relates to all types of foamed sealing tapes, namely both sealing tapes which expand in the transverse direction after being introduced into a transition between a first and a second building component, and sealing tapes which do not expand in the transverse direction. The term "sealing tape" is understood below as a generic term which includes all sealing tapes and other elongated strips or tapes which are used for sealing or for sealing attachment. A special sealing tape according to the invention is often referred to as a compression tape, which is rolled up in a compressed manner and expands with a delay after it has been unrolled. Foamed sealing tapes according to the invention can have PVC, PU or silicone foam.

Plastering strips are plastered with plaster and often seal a transition between two building components, but this is not absolutely necessary, there are also non-sealing plastering strips, and these are also covered by the present invention. Sealing strips can be used anywhere in construction where a gap between two building components needs to be sealed. Sealing strips can either be plastered in or not, for example sealing strips are used for double-shell masonry or metal parts and sheet metal profiles without plastering.

The plaster strip according to the invention is tight against rain, in particular against driving rain and wind.

The plaster strip according to the invention is for sealing placement at the transition between a first building component and a second building component certainly. The plastering strip according to the invention is suitable for a variety of installation situations, for example. It can be placed between the window frame and plaster layer, between window frame and thermal insulation, between window frame and masonry, between two masonry components, between two thermal insulation components or between a metal part, e.g. a sheet metal or an angle and a thermal insulation.

A compressed state of compression in the longitudinal direction of the sealing tape is understood to mean a compressed introduction of the sealing tape beginning with a compression of 0.1%, i.e. the longitudinally flush introduction of 1.001 m of sealing tape into a 1,000 m long receiving area of a plastic strip.

According to one of the findings on which the invention is based, the inventors of the present subject of the application have found that the sealing tape of the plastic strip of a plaster strip, when installed, is often no longer due to shrinkage or contraction in the plastic strip in the longitudinal direction at the end regions of the plastic strip extends to the end. This is due to the current manufacturing processes, in which often only a precisely fitting or tension-free insertion of the sealing tape into the plastic strip or even an introduction of the sealing tape into the plastic strip under tension or tension takes place. The overstretching of the sealing tape often results inevitably when the sealing tape is rolled up onto a roll from which the sealing tape is then later unrolled again. A sealing tape introduced under tension in this way then contracts a little, which can result in leaks at the end regions of the plastic strip. This problem is exacerbated by temperature fluctuations that occur.

According to a basic idea of the invention, the inventors have found that these sealing problems are reliable by compressing a sealing tape into a corresponding receiving area of a plastic strip can be avoided. By compressing a sealing tape or sealing tape into a receiving area of a plastic strip, material shrinkage can be compensated from the outset and such sealing problems can be reliably avoided.

The plastering strip according to the invention therefore reliably seals transitions between two building components and over their entire length.

The reserve of 1 to 3% often prescribed by the manufacturers of sealing tapes can be ensured in a simple manner according to the invention, and if sealing defects occur, the plastering strip according to the invention with the sealing tape compressed therein can be excluded with some certainty.

By providing an openable receiving area of the plastic strip, the sealing tape running therein can expand when this receiving area is opened and securely seal the transition in the transverse direction and securely fix the plastic strip therein.

The manufacturing machine for inserting a sealing tape into a receiving area of a plastic strip ensures the compressed insertion of the sealing tape in the longitudinal direction in the receiving area of the plastic strip by a sealing tape feed rate that is higher than the speed of the relative movement between the sealing strip guide unit and the plastic strip .

The peripheral speed of the sealing tape compression roller of the manufacturing machine can be greater, in particular 1% to 5% greater than the peripheral speed of the other rollers, in order to enable the sealing tape to be compressed into the receiving area of the plastic strip.

In addition, the circumference of the sealing tape upsetting roll of the production machine can be larger, in particular by 1% to 5% larger, than the circumference of the other rolls.

In addition, at least the sealing tape compression roller, the receiving area holding roller and the receiving area closing roller of the production machine can be driven by a common drive, in particular via a common V-belt.

In addition, the sealing tape supply of the production machine can have a sealing tape supply roll, from which the sealing tape with a cover tape arranged thereon is unrolled.

In addition, in the manufacturing machine, the cover tape of the sealing tape can be guided in a different direction than the sealing tape by means of at least one roller and thus pulled off the sealing tape.

In addition, a deflection roller and a pair of rollers can be provided for guiding the cover strip away.

The method for introducing a sealing tape into a plastic strip accordingly comprises bringing about a relative movement between a sealing tape guide unit and a plastic strip over the entire length of the plastic strip and introducing the sealing tape into the receiving area of the plastic strip with an opposite the speed of the relative movement increased sealing tape feed speed.

The manufacturing machine and the method ensure a simple, fast and, at the same time, reliable manufacture of a plastering strip according to the invention. The manufacturing machine and the method can also be used directly on the construction site.

The embodiments specified with reference to the production machine and the advantages associated therewith can also be implemented as corresponding embodiments of the method, with the same advantages. These embodiments of the method are not explicitly repeated again.

The manufacturing machine can be designed either with a user-driven motor or as an automatically operating manufacturing machine.

The disclosure also relates to a device, in particular a handy compression device, for introducing a sealing tape into a gap between a first building component, in particular a window frame and a second building component, in particular a building outer shell. This device is able to apply the sealing tape in a compressed state directly on the construction site in a joint or in a gap. It is possible to control the extent of the compression, for example by comparing the length of the masking tape / paper with the length of the sealing tape applied in compression. The compressed insertion of the sealing tape is ensured by the fact that when the device is moved along the longitudinal direction of the gap or joint, the sealing tape is introduced into the gap or joint at a sealing tape feed rate that is greater than the speed of movement of the device in the longitudinal direction is.

The compression with which the sealing tape is introduced into the gap can be specified by the device and can range, for example, between 1 and 3%. Manual insertion of the sealing tape by means of one or more spatulas, in which ultimately it can hardly be ensured whether the sealing tape is inserted into the gap under tension or tension, tension-free or with a compression reserve, can thus be avoided. Furthermore, with such a device, the user can easily prove that he has introduced the sealing tape with the required compression and in the correct manner into the gap or joint. The processing on the construction site is thereby facilitated and it can be proven that the processing has been carried out correctly.

The disclosure also relates to a building with a first building component, in particular a window frame, and with a second building component, in particular a building outer shell and with a gap in between, wherein a sealing tape is positioned in the gap, which is in a longitudinally compressed state . This sealing tape can be designed in a simple embodiment without a plastic strip and, for example, have been introduced into the gap by the device for introducing a sealing tape.

The sealing tape can be combined with a plastic strip in the gap of the building, which has a receiving area in which the sealing tape is positioned on the plastic strip, and the sealing tape reaching to both ends of the strip is in a compressed state in the longitudinal direction of the sealing tape.

Figure 1 (a) shows a not yet attached plaster strip 2 in cross section, in which the receiving area is closed.

In the Figure 1 (a) The plastering strip 2 shown has a first leg 4, which leads from bottom to top, and a second leg 6, which leads essentially from right to left. In the lower end area of the first leg 4, a substantially rectangular receiving area 10 for a sealing tape 12 with delayed expansion adjoins it, projecting to the right.

On the right-hand side of the first leg 4, a reinforcement fabric section 19 is attached to it with a welded connection. This exemplary embodiment involves a welded connection that has been created by ultrasonic welding by means of a separately supplied welding cord 18.

The left side of the first leg 4 and the rounded transition between the first leg 4 and the second leg 6 running obliquely downward to the left are provided with a channel profile 20.

The second leg 6 contains a protective flap 22, on the upper side of which there is a double-sided adhesive strip, not shown, so that a protective film for window or door openings can be conveniently attached there.

If window or door openings or window or door frames are mentioned here and below, it goes without saying that the plastering strips according to the invention can also be used in connection with other components, e.g. in connection with protruding beams or with window sills.

The receiving area / containment area 10 comprises an upper side leg 13 integrally connected to the first leg 4 and protruding to the right, as well as a lower area with a lower wall 14 with a projection 15 attached to the left end of the lower wall 14 and protruding obliquely upward to the right and with a right outer wall, the upper end of which is bent inward and forms a latching with the right end of the upper-side leg 13. On the underside of the left end of the lower wall 14 there is arranged a sealing lip 17 which projects obliquely to the left and below. The left end of the lower wall 14, the right end of the second leg 6 and the lower end of the transition between the first leg 4 and the second leg 6 is designed as a flexible, detachable connection area 21. An adhesive tape 24 is attached to the underside of the lower wall 14, with the aid of which the plastering strip 2 can be glued to a window frame.

Figure 1 (b) shows the plaster strip 2 with the receiving area 10 open in cross section.

According to Figure 1 (b) the flexible, detachable connecting piece 21 between the right end of the second leg 6, the left end of the lower wall 14 and the lower end of the transition between the first leg 4 and the second leg 6 has been torn off or cut through, and the second leg 6 with the protective flap 22 has been removed from the remaining part of the plaster strip 2. Furthermore, the locking between the upper end of the right outer wall 16 and the right end of the upper side leg 13 has been released. Accordingly, the sealing tape 12 is free to expand.

According to Figure 1 (b) the sealing tape 12 has expanded in the transverse direction. In this way, an advantageous and reliable seal of a transition between a thermal insulation attached to a building and an installed or yet to be installed building component, such as a window or door frame, can be achieved.

The lower wall 14 is made in one piece with the rest of the plastering strip 2, in particular with the second leg 6, with the first leg 4, with the top leg 13 and with the transition between the first leg 4 and the second leg 6, namely in a state in which the lower wall 14 is rotated about 90 degrees or more counterclockwise compared to that in FIG Figure 1 drawn situation has been pivoted. In this state, the sealing tape 12 could be inserted compressed in the longitudinal direction and then the lower wall 14 closed and locked with the top of its right outer wall 16 opposite the right end of the upper leg 13, whereby the sealing tape 12 is held together in the transverse direction and an expansion is prevented.

Apart from the reinforcement fabric section 19, the sealing tape 12 and the adhesive tape 24, the plastering strip 2 has been produced by extrusion. The sealing lip 17 can consist of a softer, more flexible material than the rest of the plastering strip 2 and can have been produced by coextrusion.

Figure 2 (a) shows a not yet attached plaster strip 26 in cross section, in which the receiving area 30 is closed.

In the case of the second plastering strip 26, identical elements are given the same reference symbols as in FIG Figure 1 designated. In contrast to the first plaster strip 2, the first leg 28 projects significantly further upwards, and the reinforcing fabric 19 is attached to the left side of the first leg 28 by means of a welding cord 18. No adhesive tape 24 is attached to the underside of the lower wall 14.

The receiving area 30 encloses the sealing tape 12. Its lower wall 14 is latched with its slightly upwardly projecting left end opposite a latching projection 32 attached to the underside of the transition area between the first leg 28 and the second leg 6. The lower wall 14 can be flexibly pivoted about its flexibly designed transition to the right outer wall of the receiving area 30.

On top of the receiving area 30 there is a barb-like projection 34. Furthermore, a cover lip 36 is provided on the right end of the second leg 6, which protrudes downward. This can consist of a softer, more flexible material than the rest of the plastering strip 26, and it can be produced by coextrusion.

Figure 2 (b) shows the plaster strip 2 with the receiving area 10 open in cross section.

According to Figure 2 (b) the lower wall 14 of the receiving area 30 has been released by unlatching its left end from the locking projection 32 and pivoted downwards. The lower wall 14 can either with the plastering strip in the transition between a thermal insulation attached to a building and an installed or yet to be installed building component, such as a window or door frame, can also be inserted. Alternatively, it can be torn off at its flexible transition area to the right outer wall.

In the plaster strips 2 and 26, the sealing tape 12 is inserted in a compressed manner within the receiving area 10, 30. A material overhang of the sealing tape at the end of the profile is provided according to the invention so that the joint area is sealed with the greatest possible reliability. An overhang of the sealing tape at the profile ends of 3 mm should be mentioned here as a sensible and practical overhang. It should also be noted that an overhang of the sealing tape with a plastering strip or a rod with a length of 2 meters of, for example, 2 cm on both sides would be technically possible, although this design is not suitable for construction because the sealing tape overhang is incorrectly positioned and would not ensure continuous compression. This execution would also be ineffective when cutting this profile to length.

Figure 3 shows the plaster strip 2 in its installed state in the transition between a thermal insulation 38 and a window frame 44 in horizontal section and a detail view.

One recognizes a small part of a building wall 46 and a part of a window frame 44 which is inserted into a corresponding opening in the building wall 46. In front of the building wall 46 and the end region of the window frame 44 there is thermal insulation 38 which is fastened to the building wall 46. Between the outwardly facing outer surface of the window frame 44 and an attachment surface of the thermal insulation 38 facing the building wall, there is a gap or transition in which the receiving area 10 of the plastering strip 2 is inserted after the second leg 6 with the protective flap 22 has previously been removed so that the transition area between the first leg 4 and the second leg 6 has been detached from the lower wall 14 is, and after the right outer wall 16 has been unlatched from the top leg 13.

The plastering strip 2 thus rests with the underside of its adhesive tape 24 on the outer surface of the window frame 44, its right outer wall 16 rests on the end of the gap, its upper leg 13 rests on the thermal insulation side of the gap, which is opposite the outer surface of the window frame 44 , on.

One can also see the reinforcing material 19 extending perpendicularly away from the window frame 44, which is provided with filler and adjoined by the fabric that covers the reveal surface 39 of the thermal insulation 38 and which is also provided with filler. External plaster 42 is applied to the filler with fabric 40. The filler goes through the mesh openings of the reinforcement fabric 19 and the fabric adjoining it to the reveal surface 39.

This in Figure 3 Sealing tape 12, shown expanded in the transverse direction, represents a sufficiently good sealing of the gap; in addition, there is also a certain additional fastening effect there.

The detailed view of the gap between the thermal insulation 38 and the window frame 44 also shows that the external plaster 42 extends as far as the channel profile 20, where it is held well due to the enlarged surface.

The longitudinally compressed insertion of the sealing tape 12 into the receiving area 10 ensures that there is no shrinkage at the upper and lower end of the plastering strip 2 and that the upper and lower end of the plastering strip 2 thus also fill the gap in a sealing manner and the plastering strip 2 is good therein fix.

Figure 4 FIG. 10 shows a front view of a manufacturing machine 50.

The manufacturing machine 50 is designed as a machine for compressing a sealing tape into a plastic strip, in particular a plaster strip or a sealing strip, and, viewed from right to left, it has a support area 52, a processing area 54 and a removal area 56. Even if the production machine 50 is always explained below with reference to a plastering strip, it is just as suitable for the compressed introduction of a sealing tape into any plastic strip, in particular also into a sealing strip.

A control 58 is arranged below the processing area 54, which controls the sequence of the method for the compressed introduction of the sealing tape into the plastering strip. In the processing area 54, a linear unit 60 is arranged above the processing plate and runs in the horizontal direction from the left end of the processing area 54 to its right end. A plastering strip holder is provided below the linear unit 60 directly below the underside of the movable slide 64. To the left of the linear unit 60, a drive motor 62 is provided, which drives a movable slide 64, which can be mounted on ball bearings, via a toothed belt, not shown here. The movable carriage 64 is shown in a left starting position A and in a right end position B.

During operation of the production machine 50, a plastering strip, as shown in FIGS. 1 and 2, is placed on the right-hand support area 52, at a small distance from the preceding plastering strip, which is still in the processing area 54. The movable slide 64 is in position A. The plastering strip in the processing area 54 and a piece of the plastering strip that is located in the support area 52 are shown in FIG Figure 4 Clamping devices not shown, in particular pneumatic clamps, clamped.

The manufacturing machine 50 is then started, the movable carriage 64 is moved by the drive motor 62 over the entire length of the plastering strip located in the processing area 54, and the sealing tape 12 is thereby, as on the basis of FIG Figures 5 and 6 will be explained in more detail, rolled up compressed into the receiving area 10 of the plaster strip and the receiving area of the plaster strip is then closed.

The plastering strip preceding the plastering strip in the processing area 54, which is already located in the removal area 56, is removed after severing the sealing tape continuously discharged from the movable carriage 64 at the interface to the left of position A of the movable carriage 64.

The movable carriage 64, which is now in position B, now moves back to position A, with the two strips that were previously located in the support area 52 and in the processing area 54 being dragged along and displaced by one position so that they are then in the Processing area 54 and in the removal area 56 are located. A new plaster strip is now brought into the support area 52 and the process is repeated.

Figure 5 shows a schematic front view of a roller arrangement 66 with a sealing tape 86 guided over it and a plastering strip 67, in the receiving area 10 of which the sealing tape 12 is introduced compressed in the longitudinal direction by means of the roller arrangement 66.

Even if the roller arrangement 66 is always explained below with reference to a plastering strip, it is also suitable for the compressed introduction of a sealing tape into any plastic strip, in particular also into a sealing strip.

The roller arrangement 66 can either, as in the case of the production machine 50 in FIG Figure 4 realized, be arranged on a movable slide, which is moved with respect to the fixedly positioned plastering strip 67 in order to introduce the sealing tape 86 compressed into the receiving area of the plastering strip 67.

Alternatively to this, the roller arrangement 66 can also be arranged in a stationary manner, and the plastering strip 67 is moved at a certain speed with respect to the roller arrangement 66, so that the sealing tape 86 is compressed into the receiving area of the plastering strip 67.

As an alternative to this, it is also conceivable for both the roller arrangement 66 and the plastering strip 67 to be moved relative to one another.

In all variants, it is only important that a relative movement is brought about between the roller arrangement 66 and the plastering strip 67, and that, as will be explained later, the sealing tape feed speed is greater than the speed of the relative movement, so that the sealing tape is longitudinally is compressed into the receiving area of the plaster strip 67.

The roll assembly 66 has a sealing tape supply roll 68 on which is wound a sealing tape 86 with masking tape 84 attached thereto that covers the adhesive underside of the sealing tape 86. The cover tape 84 is transferred from the sealing tape feed roller 68 via a cover tape deflection roller 72 to a pair of rollers comprising a first cover tape removal roller 74, which can be designed as a toothed metal wheel, and a second cover tape removal roller 76, which can be designed as a solid rubber roller, guided away, so that the cover tape 84 is removed from the sealing tape supply roll 68 when the sealing tape 86 is unrolled.

With its adhesive underside directed to the right or downward, the sealing tape 86 reaches the sealing tape compression roller 78, which has a slightly larger diameter than the subsequent receiving area holding roller 80 and the subsequent receiving area closing roller 82. The sealing tape 86 is rolled by this sealing tape compression roller 78 into the FIGS Figure 5 Undetectable receiving area 10, which is held up by the receiving area hold-open roller 80, is introduced. The receiving area closing roller 82 arranged to the left thereof closes the receiving area of the plastering strip 67 again.

When designing the roller assembly 66 for the in Figure 1 The plastering strip 2 shown, the plastering strip 2 is positioned with the first leg 4 protruding downwardly opposite the roller arrangement 66, the reinforcing fabric 19 already being attached to the plastic profile. The receiving area hold-open roller 80 pivots the section with the lower wall 14 and with the right outer wall 16 of the receiving area 10 around the flexible, releasable connecting piece 21 such that the sealing tape compression roller 78 compresses the sealing tape 86 onto the upper side leg 13, compressed in the longitudinal direction the lower wall 14 applies. The receiving area closing roller 82 then pivots the lower wall 14 and the right outer wall 16 of the receiving area 10 of the plastering strip 2 so that the right outer wall 16 engages with the upper leg 13 and closes the receiving area 10 with the sealing tape 12 now inserted therein.

The in Figure 5 The arrow shown at the bottom right indicates the plastering strip draw-in direction 88. In the case of a stationary roller arrangement 66, the plastering strip 67 would be moved in the same direction in order to introduce the sealing tape 86 through the sealing tape compression roller 78.

In the case of a stationary plastering strip 67 and a roller arrangement 66 optionally arranged on a movable slide 64, as shown in FIG Figure 4 shown is the Direction of movement of the roller arrangement 66 of the plastering strip draw-in direction 88 is opposite.

The roller arrangement 66 also has a plastering strip draw-in roller 70, which is provided in particular for the embodiment with a stationary roller arrangement 66 and moving plastering strip 67.

A distance from the plastering strip 67 can be seen below the sealing tape compression roller 78. As an alternative to this, the sealing tape compression roller 78 can also press the sealing tape 12 directly onto the plastering strip 67, so that this gap is eliminated.

In the case of the roller arrangement 66, a sealing tape separation position 90 is drawn between the receiving area hold-open roller and the receiving area closing roller 82, at which the sealing tape 12 is cut off between two successive plaster strips.

The introduction of the sealing tape 12 compressed in the longitudinal direction into the receiving area 10 of the plastering strip 67 is achieved according to the roller arrangement 66 by a peripheral speed that is higher than that of the other rollers 80 and 82. It is advantageous to bring about a circumferential speed increased by 1 to 5% and accordingly a compression of 1 to 5%.

According to one embodiment, at least the rollers 78, 80 and 82 are connected via a common V-belt, and the circumference of the sealing tape compression roller 78 is increased by 1 to 5%, preferably by about 3%, compared to the circumference of the rollers 80 and 82. This results in a compressed introduction of the sealing tape 12 into the receiving area 10 of the plastering strip 67 in a simple manner.

Figure 6 FIG. 9 shows a schematic sectional view of a roller assembly 92.

The sealing tape feed roller, the receiving area holding roller and the receiving area closing roller are not shown. The removal and removal of the cover tape 80 takes place via a smaller cover tape deflection roller 98 and a pair of rollers 100 and 102, which are also smaller cover tape removal rollers. These are arranged approximately at the level of the underside of the sealing tape compression roller 94. In the schematic view of Figure 6 If the second cover tape removal roller 102 is arranged too low, it would have to be shifted slightly upwards so that it does not collide with the plastic strip 104.

In addition to the sealing tape upset roller 94, which is substantially the same as the seal tape upset roller 78 according to FIG Figure 5 corresponds to, for better guidance of the sealing tape 86 with the cover tape 84 still applied there, a sealing tape guide roller 96 is arranged on the opposite side of the sealing tape 86.

As in Figure 6 can clearly be seen, the sealing tape 86 is pressed directly onto the plastic strip 104 by the sealing tape compression roller 94, without a gap being provided.

In Figure 6 the relative speed v _rel and the upsetting speed v _{upset are} indicated by two arrows pointing to the left. The upsetting speed, which results from the circumferential speed of the sealing tape upsetting roller 94, is somewhat greater than the relative speed between roller arrangement 92 and plastic strip 104, so that, as in FIG Figure 6 It can also be seen from the illustration of the material of the sealing tape 86 that the sealing tape 86 is compressed in the longitudinal direction and introduced into the receiving area 10 of the sealing tape 104 and, if necessary, glued in place.

According to a further embodiment, in the case of the roller arrangements 66 and 92, further special wheels can be provided between the sealing tape feed roller 68 and the sealing tape compression roller 78/94, over which the sealing tape 86 runs.

The drive motor can be designed as a speed-regulated motor, in particular as an electric motor. As a result, the sealing tape feed rate can be adjusted independently of the relative movement between the sealing tape guide unit and the plastering strip.

In an alternative embodiment of the Figure 6 the roller arrangement 92 and the sealing tape feed roller (not shown) are integrated in a handy compression device, and the reference number 104 does not represent a plastering strip, but rather the bottom of a gap or a joint into which the sealing tape 86 is introduced directly in the compressed state without a plastic strip with a receiving area or the like is provided for the sealing tape 86.

Further special wheels over which the sealing tape 86 runs can be provided between the sealing tape feed roller and the sealing tape compression roller 94.

In use, the upsetter is applied to one end of the gap and the sealing tape 86 is applied to the bottom of the gap. The upsetting device is then moved along the gap, with the sealing tape upsetting roller 94 ensuring a sealing tape feed speed which is greater than the speed of the longitudinal movement of the upsetting device. This can be ensured by a correspondingly higher peripheral speed of the sealing tape compression roller 94. In practice, the upsetting device can have a wheel which runs alongside the gap and thus detects the feed speed of the upsetting device in the longitudinal direction. This wheel can be connected directly or indirectly to the sealing tape compression roller 94, which compared to this wheel has a circumferential speed increased by the desired compression to be achieved.

When the upsetting device has arrived at the opposite longitudinal end of the gap, the sealing tape 86 is cut off and the end of the sealing tape 86, if necessary, is manually inserted into the gap end.

By adjusting the peripheral speed of the sealing tape compression roller 94, the compression with which the sealing tape 86 is introduced into the gap can be adjusted as desired.

A drive motor can also be provided for the upsetting device.

A narrow design of the upsetting device is advantageous for narrow gap situations.

The sealing tape is introduced into the gap in a simple manner and with precisely the desired compression using the compression device. The correct compressed application of the sealing tape is thus guaranteed and can be proven later, e.g. by measuring the cover tape / cover paper.

Figure 7 shows a sealing tape 114 in its inserted state in the gap between a building outer shell 110 and a window frame 112 in horizontal section.

In Figure 7 a two-shell masonry with an inner building shell 106, with an outer building shell 110 and with an air and insulation layer 108 arranged between them is shown. A window frame 112 is provided with a suitable one Insulating material attached to the building inner shell 106. Between the building outer shell 110 and the front of the window frame 112 there is an elongated gap which is shown in FIG Figure 7 is formed in the building outer shell 110. In this gap is according to Figure 7 a sealing tape 114 introduced compressed in the longitudinal direction. The gap can also be made deeper and extend, for example, as far as the air and insulation layer 108 or as far as the building inner shell 106, in which case the thickness of the sealing tape 114 is to be selected appropriately.

This introduction of the sealing tape 114 into the gap is possible in particular by using the method with reference to FIG Figure 6 described handy upsetting device takes place.

Figure 8 (a) shows a plastic strip 116 not yet attached in cross section.

The plastic strip 116 comprises a receiving area 118 which, like the inclusion area 10 of the plastering strip 2, has a lower wall 122, a projection 124 attached to the right end of the lower wall 122 and protruding obliquely to the left, a left outer wall 126, which extends to the lower Wall 122 connects and the upper end is bent inward and forms a latching with the left end of the cover flap 134, as well as the upper cover flap 134 which runs parallel to the lower wall 122 and whose right end is bent downwards and at the right end of the lower wall 122 forms a flexible, releasable connection area 136 with the lower wall 122.

A protective flap 132, which protrudes to the right, is attached to the cover flap 134, on the upper side of which there is a double-sided adhesive strip, not shown, so that a protective film for window or door openings can be easily adhered there.

An adhesive tape 128 is attached to the underside of the lower wall 122, with the aid of which the plastic strip 116 can be glued to a window frame or the like. On the underside of the right end of the lower wall 122 a sealing lip 124 is arranged obliquely downwards to the right.

The introduction of the sealing tape 120 compressed in the longitudinal direction into the receiving area 118 ensures that no shrinkage occurs at the upper and lower ends of the plastic strip 116.

Figure 8 (b) shows the plastic strip 116 with detached protective tab 132 and cover tab 134.

According to Figure 8 (b) the protective tab 132 and the cover tab 134 have been separated from the rest of the plastic strip 116 and pulled away to the right. In practice, this is done by kinking or severing the protective flap 132, as a result of which the flexible, detachable connecting area 136 is separated, and then by pulling away the protective flap 132 with the covering flap 134 hanging on it to the right. Accordingly, the sealing tape 120 is now free to expand.

According to Figure 8 (b) the sealing tape 120 has expanded in the transverse direction. In this way, an advantageous and reliable seal of a transition between two building components can be achieved.

Figure 8 (c) shows the plastic strip 116 in its state in the gap between plaster 124, 146 and a window frame 140.

A small part of a building wall 138 and part of a window frame 140 which is inserted into a corresponding opening in the building wall 138 can be seen. In front of the building wall 138 and next to the end area of the window frame 140 a base plaster layer 144 and a top plaster layer 146 arranged thereon can be seen.

Between the plaster layers 144 and 146 and the outwardly directed outer surface of the window frame 140 there is a gap or transition into which the plastic strip 116 with its receiving area 118 is inserted. A cover paper has previously been detached from the adhesive tape 128, and the plastic strip 116 has been glued with the adhesive tape 128 onto the side surface of the gap on the window frame side.

The protective flap 132 is then bent and pulled out of the gap together with the cover flap 134. The sealing tape 120 is now expanding in the transverse direction, as shown in FIG Figure 8 (b) is shown, and is pressed tightly against the plaster-side side surface of the gap. The plastic strip 116 thus provides a sufficiently good seal for the gap, and there is also a certain additional fastening effect there.

Figure 9 shows the plastic strip 116 in its state introduced into the gap between a clinker brick facing 154 and a metal angle 150.

In front of the building wall 138, which can be made of concrete, there is a mineral wool insulation layer 148, to which in turn a clinker brick lining 154 is attached by means of a mortar 152. A metal angle rail or a metal angle 150 is fastened between the building wall 138 and the mineral wool insulating layer 148 and is located to the left of the mineral wool insulating layer 148, the mortar 152 and the clinker brick lining 154 up to the level of the outer surface of the clinker brick lining 154 extends. The metal angle 150 forms a kink to the left approximately at the level of the outer surface of the mineral wool insulation layer 148. In the gap between the clinker brick facing 154 and the front section of the metal angle 150 there is a gap or a transition between Clinker brickwork 154 and the front section of metal bracket 150.

The plastic strip 116 is inserted into this gap and glued with the underside of the adhesive tape 158 onto the side surface of the gap on the metal angle side. The protective flap 132 is detached from the lower wall 122 of the plastic strip 116, for example by kinking, and pulled out of the gap together with the cover flap 134. The sealing tape 120 has then expanded in the transverse direction and pressed against the clinker-side side surface of the gap. This gap is thus well sealed and there is also an additional fastening effect.

In the embodiments of Figures 8 and 9 the longitudinally compressed insertion of the sealing tape 120 into the receiving area 116 and the particularly flush insertion of the plastic strip 116 into the gap at the upper and lower end of the gap ensure that there is no shrinkage at the upper and lower end of the gap and thus the upper and lower end the plastic strip 116 can fill the gap in a sealing manner and fix the plastic strip 116 well therein.
