Description

Description: The invention relates to a device for creating a transition between a sanitary device and a vertical surface, and to a method for creating such a transition and a wet or wet region with such a transition.

There are in and on buildings in the wet or wet area transitions between sanitary and walls, which are nowadays usually made with connection tapes.

Over time, subsidence may occur in which cracks may form in the region of a connecting band or show separation phenomena. Also in the area of expansion joints such effects can occur.

Therefore, there are now connection tapes, such as the 5-star tape from Schaco AG, Switzerland, which have a Dehnzone. Through the use of such a stretch zone tearing or detachment of the connecting band can be prevented.

The construction of such connection bands is usually complicated and the bands are therefore expensive. In addition, the installation of such connection tapes is not always easy.

It has as its object to provide a device which is ideally suited as a transition between a sanitary device and a vertical surface and which is easy to handle and easy to install.

This object is achieved by a device according to claim 1. A corresponding method can be found in claim 11. A corresponding wet or wet area can be deduced from claim 12. Advantageous embodiments are contained in the subclaims.

The device of the invention is specifically designed for making a transition between a sanitary device and an on-site vertical or horizontal surface. The device has a flat, strip-like basic shape which is defined by a strip length which runs parallel to a longitudinal axis and a strip width which is perpendicular to the longitudinal axis. The device of the invention comprises: a first extensible web comprising an elastic base material extending parallel to the longitudinal axis, a second web extending parallel to the longitudinal axis and along a longitudinal edge flat on a side surface of the first web arranged and connected to it to define a first strip-shaped zone of the device, the device having a second strip-shaped region of the first web, which extends parallel to the longitudinal axis and which is defined by the fact that the first web in this strip-shaped region is provided with a protective layer so as to define a stretch zone.

The second track may be intimately connected to the first track in all embodiments.

The second web can be connected in all embodiments by gluing, vulcanizing, melting or pressing with the first web.

The second web can be connected in all embodiments by sewing or pinning to the first web.

The second track may in all embodiments include a material that differs from the base material of the first track in that it is not or hardly elastic.

The first web should preferably have a modulus of elasticity (modulus of elasticity) smaller than 10 GPa in all embodiments. Particularly suitable are first webs which have a modulus of elasticity (modulus of elasticity) which is less than 1 GPa.

The device of the invention can be used in all embodiments in the following, exemplified, sanitary facilities: bathtubs, shower trays, shower channels, gutters or pots, sinks, vanities or furniture, basins etc.

The device of the invention can be used in all embodiments, for a transition between a vertical surface (-Zarge) of a sanitary device and an on-site vertical surface (eg a wall) or for a transition between a vertical surface (-Zarge) of a sanitary device and an on-site horizontal surface (eg a floor) to provide.

The most diverse applications in or on buildings are summarized here with the term "wet and wet area".

Preferably, the device of the invention in all embodiments can be used where there is a gap between tiles, stoneware, slabs or other wall coverings, which is typically grouted with silicone.

Preferably, the device of the invention comprises in all embodiments in addition to a first strip-shaped zone and a second strip-shaped region a second strip-shaped zone, wherein the second strip-shaped region between the first strip-shaped zone and the second strip-shaped zone is arranged.

Optionally, the device of the invention may comprise a cut protection strip. Such a cut protection strip can either be connected to the first web by means of a pressure-sensitive adhesive, or the cut protection strip can be supplied as a separate strip for insertion into a longitudinal gap (called a standing constellation), or the cut protection strip can be provided as a separate strip in a hanging constellation in front of the first web be arranged. If necessary, the cut protection strip can also be separated from the pressure-sensitive adhesive, if the specific mounting situation does not permit or require cut protection strips.

The optional cut protection strip may in all embodiments a metallic material (eg a CNS foil or a CNS lattice or mesh) and / or a plastic material (eg a highly reinforced polyethylene) and / or a composite material (eg a fleece or fabric aramid and / or other cut-resistant fibers) which, due to its structure and / or material property (s), provides protection against damage or cutting with a sharp object (eg with a knife).

The cut protection strip should have a cut resistance according to DIN EN 388 test with a factor (also called cutting index) of greater than or equal to 5 in all embodiments. Even if this DIN EN 388 refers to the testing of protective gloves against mechanical risks, it can be transferred 1: 1 to the sanitary area.

The cut protection strip should be excellent in all embodiments not only by a sufficiently large cut resistance but also by a high puncture resistance.

The cut protection strip should have a puncture resistance according to DIN EN 388 test with a puncture force of greater than or equal to 60N in all embodiments.

The cut resistance can be achieved in all embodiments by addition / addition of fibers, spheres or granules in the plastic material or in the composite material. Metallic cut resistant strips usually do not need such additions or admixtures, but can optionally be coated, backed or reinforced to improve cut resistance.

Particularly suitable as cut protection strip is a metal grid structure, a plastic grid structure, a fabric grid structure or a fiber grid structure. It is also possible grid structures of a combination of two or more than two of these materials.

By definition, such a lattice structure should be a (fixed) net, woven fabric, mesh, perforated lattice, expanded metal or scrim that is flexible or at least manually bendable in the plane. The lattice structure should therefore not have high inherent rigidity in the plane (called bending stiffness), so that the optional cut protection strip can also be guided around small radii (less than or equal to 5 mm).

Furthermore, the terms "strip" or "band" to indicate that the geometry in one direction, the so-called "strip longitudinal direction" or "strip length", extends far, while the measured perpendicular thereto width and thickness of the strip less are.

The width of the device of the invention may be, for example, between about 4 cm and 20 cm in all embodiments.

The overall thickness of the device of the invention may typically be between about 0.5 mm and 8 mm in all embodiments.

The first web of the device of the invention may in all embodiments have a thickness which is between 0.1 and 2 mm.

The first web of the device of the invention may be designed in all embodiments specifically so that the surface of the front and / or back is designed to be rough or porous, or that the surface is designed in another way adhesion-promoting (eg by the one-sided or two-sided lamination or (warm) pressing a self-elastic nonwoven material).

The protective layer can be connected in all embodiments from the factory with the first track of the device. However, in all embodiments, the protective layer can also be supplied as a separate component in order to then connect the protective layer to the first path of the device on site. The connection to the first web of the device may be prior to assembly of the device, or it may be done in an intermediate step after assembly of the first web.

The protective layer may in all embodiments comprise only one material (e.g., an adhesive or impregnation).

However, in all embodiments, the protective layer may also comprise two or more than two materials. Thus, e.g. in all embodiments, a thin, preferably flexible, plastic strip be provided on the back with an adhesive layer to serve as a protective layer.

Preferably, all embodiments include a plastic film which is provided on the back with a pressure-sensitive adhesive as an adhesive layer.

As a protective layer, in all embodiments, a combination of a plastic strip (e.g., a plastic film) and a cut protection strip may serve.

In all embodiments, the protective layer may at least partially overlap or overlap the second sheet and extend beyond the first strip-shaped zone into the second strip-shaped zone to protect the stretch zone there.

In all embodiments, however, a cut protection strip can be used, which is provided on the back with a double adhesive strip, wherein at least one adhesive layer of this double-adhesive strip has a pressure-sensitive adhesive. In this case, the combination of cut resistant strips with double adhesive strips serves as a protective layer.

The device of the invention may be two-ply or multi-ply in all embodiments.

The device of the invention may comprise in all embodiments on the room side and / or on the wall side a soundproofing strip.

The device of the invention may optionally comprise, in all embodiments on the front side, a stretchable nonwoven, fibrous or web material, e.g. to facilitate embedding in a liquid material (e.g., a liquid seal or a sealing slurry).

An area of the backside of the device of the invention may optionally be provided with an adhesive (e.g., butyl) in all embodiments for securing the device to a vertical or horizontal surface (e.g., wall or floor).

Further details and advantages of the invention will be described below with reference to embodiments and with reference to the drawings. It should be noted that the drawings are not to scale. Above all, the thicknesses of the various elements are not shown in real relationship to each other.

In the following location and direction are used to describe the invention better. These details refer to the respective installation situation and should therefore not be interpreted as a restriction. In order to be able to better define the location and direction information, a reference to the wall 2 (also called vertical area 2) is also made in part, in which e.g. from a wall-near element, a wall facing, wall facing away from the surface or a wall-parallel assembly is the speech.

The invention will be described below with reference to some embodiments.

These are devices 5 (also referred to as sealing or terminal strips) which are e.g. can serve to provide a tight transition in the connection area between a bathtub, or other sanitary device 1, and a wall surface or bottom surface 2. A corresponding example is shown in FIG. 4. As sanitary facilities 1 bathtubs, shower trays, shower trays, sinks, troughs, basins and the like are called.

The devices 5 of the invention have a flat, strip-like basic shape, which is defined by a strip length Lx, which runs parallel to a longitudinal axis x and by a strip width b, which runs parallel to a transverse axis y. The stripe width b is perpendicular to the longitudinal axis x, e.g. can be seen in Fig. 1A.

In the figures, various embodiments are shown in flat form either in a front view (see Fig. 1A) or in a sectional view. The sectional views are shown in part in a kind of exploded view.

The strip length Lx defined with the perpendicular strip width b a plane E (x-y plane). In Fig. 1C, the plane E is indicated by a dashed line. In the illustrations of FIGS. 1A and 1B, the plane E lies in the plane of the drawing.

The device 5 of the invention is designed in all embodiments, in particular for use in the wet and wet area 100 of a building. Corresponding examples of suitable devices 5 are shown in the figures.

The devices 5 of the invention comprise in all embodiments a first stretchable web 6 of elastic base material. This elastic base material has in all embodiments at least one extensibility in the transverse direction parallel to the y-axis (also called transverse ductility).

In all embodiments, a thermoplastic elastomer (TPE) and / or an acrylonitrile-butadiene rubber (also abbreviated NBR) can be used as a base material, wherein the first web 6 in this case has a thickness between 0.2 and 0, 8 mm has.

In all embodiments, a plastic nonwoven fabric, mesh, grid, or net can be used, which is coated with plastic, laminated or covered, so as to obtain a first stretchable web 6. Particularly suitable is a TPE-coated polypropylene nonwoven which is extensible and longitudinally stable.

The elastic base material may in all embodiments also have a longitudinal extensibility parallel to the x-axis (also called longitudinal extensibility).

In particular, the transverse extensibility is of great importance, since settlement phenomena can occur between the sanitary device 1 and the vertical surface 2 (for example a wall 2) and expansion movements in the area of expansion joints. So it can be e.g. Over time, due to drying processes, temperature fluctuations and other processes, a bathtub 1 moves a few millimeters relative to a wall 2 next to it.

Therefore, the device 5 of the invention is preferably designed in all embodiments to be able to compensate for such settlement movements and stretching movements or record. A device 5 of the invention therefore has an expansion zone DZ which, in all embodiments, permits transverse extensibility, preferably in the range between 1 mm and 2 cm.

The expansion zone DZ is preferably in all embodiments by at least 50% parallel to the y-axis stretchable. If the stretch zone DZ is e.g. has a width b2 parallel to the y-axis, which is 2 cm, then the width b2 can be increased to at least 3 cm. With the extensibility of at least 50%, there is sufficient freedom to give in settlement movements and the like, without the basic functions of the device 5 fail. The basic functions, depending on the embodiment, denote the tightness and the ability for sound insulation or decoupling.

The extensibility in the region of the expansion zone DZ is preferably between 60% and 320%. This results in sufficient leeway to be able to yield subsidence movements and stretching movements even under extreme conditions without the basic functions failing.

The elastic base material of the first web 6 preferably has a modulus of elasticity which is less than 100 N / mm 2 in all embodiments. More preferably, the modulus of elasticity in all embodiments is less than 10 N / mm 2.

In order to be able to assemble the first web 6 securely and firmly with other materials and / or layers to form a device 5 ready for assembly, the first web 6 in all embodiments preferably has a side surface (here the front side 6.3) which has good adhesive properties. or compound properties. The importance of this aspect of the invention can be particularly well described by comparison with a rubbery, smooth material (such as a bicycle tube). A rubbery, smooth material typically has high elasticity (i.e., a very small modulus of elasticity). To be able to connect a layer of another material with the rubbery, smooth material, special bonding techniques must be used. The bicycle hose must e.g. the surface is first roughened, then e.g. to be able to vulcanize a patch.

The invention is therefore based on embodiments in which the at least one side surface of the first web 6 has good adhesion or connection properties. Preferably, in all embodiments, both side surfaces 6.3, 6.4 of the first web 6 have good adhesion or connection properties.

For this purpose, the side surface 6.3 / can the side surfaces 6.3, 6.4 of the first web 6 in all embodiments, e.g. have a net, fabric, fleece or fiber-like surface. However, this type of surface must be chosen so that the transverse extensibility and the optional longitudinal extensibility of the elastic base material of the first web 6 is substantially maintained. That the net, fabric, fleece or fibrous surface itself must also be ductile.

In addition, the first web of material 6 must have sufficient flexibility in the plane E to be suitable as part of a device 5.

If this is a thin strip or material, then this strip or this material has a thickness (perpendicular to the plane E, or parallel to the z-axis), which is less than 5 mm and preferably thinner than 3 mm.

The devices 5 of the invention comprise in all embodiments, in addition to the first web 6, a second web 40 which also extends parallel to the longitudinal axis x.

This second web 40 runs along a longitudinal edge 6.1 of the first material web 6, as can be seen in FIG. 1B. The second track 40 may in all embodiments be flush with the longitudinal edge 6.1, as shown in FIGS. 1B, 1C, 2A, 3A, 3B, 3C, 3D, 3E and 3F, or it may extend slightly above the longitudinal edge 6.1, as shown in FIG 2B, or it may extend slightly below the longitudinal edge 6.1, as indicated in FIG.

In all embodiments, the second track 40 may be arranged on a side surface 6.3, 6.4 of the first track 6 and connected thereto in order to define a first strip-shaped zone Z1 of the device 5. The first strip-shaped zone Z1 is marked by a curly bracket in FIGS. 1B, 2A, 2B, 3A to 3F. In the figures, only embodiments are shown in which the second web 40 is connected flat to the front 6.3 of the first web 6. However, in all embodiments, the second track 40 can also be connected in a planar manner to the rear side 6, 4 of the first track 6, or both a track 40 on the front side 6, 3 and a further track on the rear side 6, 4 can be arranged.

The following aspect is important in the context of the second web 40. The fact that the second web 40 is connected to the elastic base material of the first web 6, the elasticity, or the extensibility of the first web 6 is significantly reduced. The first web 6 is thus stiffened by the connection with the second web 40 in the region of the first strip-shaped zone Z1, as far as the transverse and longitudinal extensibility is concerned.

By way of example, two different approaches with respect to the second material web 40 will be described with reference to FIGS. 2A and 2B.

In Fig. 2A, an embodiment is shown in which the material of the second web 40 is intimately connected to the base material of the first web 6. 2A, it is shown in schematic form that the first web 6 may have an open (surface) structure (e.g., a mesh, net, web, nonwoven, or fibrous structure). Now, if the material of the second web 40 is applied in liquid form, then this material penetrates (depending on the viscosity) into spaces, holes, pores or meshes of the first web 6. This effect is illustrated in FIG. 2A in purely schematic form. This type of connection is referred to here as an intimate connection.

An embodiment according to Fig. 2A may e.g. by applying butyl (for example from a barrel smelting plant) in viscous form to the first web 6 in the area Z1. The result is an intimate connection, which, after curing, the first web 6 in the zone Z1 takes the stretchability. Analogously, also strip goods can be applied.

In Fig. 2B an embodiment is shown in which the material of the second web 40 is e.g. is connected by means of an adhesive 43 with the base material of the first web 6. FIG. 2B again shows in schematic form that the first web 6 may have an open structure, as already mentioned. The adhesive 43 penetrates, depending on the selected nature of the adhesive 43, not or hardly in the first track 6 a. This is a sandwich-type compound. Nevertheless, this makes the zone Z1 quasi dimensionally stable.

In one embodiment of Fig. 2B, the material of the second web 40 may be e.g. to act a foam that can serve as sound isolation between the sanitary device 1 and the wall or the bottom 2. It is further indicated in FIGS. 2A and 2B that an optional protective film or liner 41 may be used to protect the second web 40 temporarily (until the time of assembly). The use of an optional protective film or sheet 41 makes sense above all if the web 40 comprises an adhesive material (for example butyl) or if the web 40 is covered on the room side with an adhesive 42 (see Fig. 2B). Also shown in Fig. 1A is a short section of an optional protective film or sheet 41.

The devices 5 of the invention in all embodiments, in addition to the first web 6 and the second web 40, comprise a second strip-shaped region, designated by the reference numeral Z3. This second strip-shaped region Z3 is provided / defined directly on the first web 6.

The second strip-shaped region Z3 in all embodiments again extends parallel to the x-axis. In addition, it has a transverse extent, width b2 in Fig. 1B, which is perpendicular to the x-axis.

The second strip-shaped region Z3 may in all embodiments start immediately above the second web 40, as shown in FIG. 1B, or it may have a small distance to the second material web 40. However, it is also possible in all embodiments that the second strip-shaped region Z3 and the second web 40 overlap a piece, as indicated in Fig. 3A.

In order to understand the meaning and purpose of this second strip-shaped region Z3, the situation in the mounted state will be discussed briefly below. In this context, reference is made in particular to FIG. 4. In this figure, an exemplary installation situation is shown in an exploded view.

The device 5 is, as already mentioned, specifically designed to create a transition between a permanently mounted device 1 (here a bathtub) and a site-side surface 2 (here a vertical wall section 2). The device 5 comprises the first web 6 extending as a web along a longitudinal axis Lx, e.g. Fig. 1A can be seen. The longitudinal axis Lx is perpendicular to the plane of FIG. 4.

In the embodiment shown, the first track 6 is designed to be arranged wall-parallel in the assembled state, as shown in FIG. 4. The first web 6 is connected to the wall 2 in a strip-shaped region Z2 (see FIG. 1A). In Fig. 4, a liquid seal or sealing slurry 4 is shown by two dotted lines. The liquid seal or sealing slurry 4 can be applied to the front of the wall 2 before the first web 6 is inserted with its strip-shaped region Z2 in the liquid seal or sealing slurry 4. Then, in order to improve the adhesion and sealing effect, another layer of the liquid seal or the sealing slurry 4 can be applied over the strip-shaped region Z2. This type of connection is referred to herein as embedding, since preferably in the area Z2 both sides of the first web 6 are intimately connected to the liquid seal or the sealing slurry 4. If the first web 6 is open / continuous (e.g., by providing cutouts or if the base material has open mesh, mesh, mesh, or fabric areas), then the base material can be penetrated by the liquid seal or sealing slurry 4.

Thus, during assembly in the zone Z2, a stiffening of the originally elastic material of the first web 6 occurs.

According to the invention, by the use of the protective layer 20, the stretch zone DZ is defined either by the extensibility of the elastic base material or the first web 6 after assembly, i. after the creation of the transition between a sanitary device 1 and a surface 2, is maintained, or that the extensibility of the elastic base material, respectively the first web 6, when creating the transition is temporarily limited, however, when a lateral force in the assembled state is available ,

In Fig. 4 it is indicated that in a wet or wet area 100 mostly tiles 7 or another wall covering are laid on the room side. FIG. 4 shows schematically that a tile adhesive or mortar 8 can be used. Since the tile adhesive or mortar 8 is typically drawn off with a toothed spatula, the tile adhesive or mortar 8 in FIG. 4 has a correspondingly structured surface on the room side. Also, the mentioned tile adhesive or mortar 8 can penetrate up to the base material of the first web 6. If this is the case, the first web 6 is additionally stiffened in zone Z2.

The statement made above also applies to other forms of assembly in which the first web 6 is not embedded in a region of zone Z2 in a liquid seal or sealing slurry.

The first web 6 may also be bonded to a face 2 adhesive in all embodiments, or a separate strip of material (eg, adhesive tape) may be applied to overlap the zone Z2 to secure the web 6 to the web Area 2 to connect.

Finally, the first web 6 in zone Z2 will lose its elasticity at the latest during assembly. This is independent of the assembly or connection technology used.

At this point, the invention begins. By attaching or providing a protective strip, a protective layer or protection zone 20, either the extensibility of the first web 6 during and after assembly is obtained, or the first web 6 is covered or protected in the strip-shaped region Z3 in such a way that the extensibility in the occurrence of Transverse forces (in the case of subsidence movements) can be effective, even if it was temporarily impaired (eg due to careless or inappropriate assembly).

Three approaches are described here, all of which serve the "protection" or the "definition" of the expansion zone DZ. The approaches described below in connection with FIGS. 3A to 3C can be used in conjunction or in combination with all other variants of the invention.

FIG. 3A shows an approach based on the use of a pressure-sensitive adhesive 22. This pressure-sensitive adhesive 22 serves as a protective strip or protective layer of the expansion zone DZ. As can be seen in FIG. 3A, this pressure-sensitive adhesive 22 may optionally extend slightly below the second web 40. The adhesive 43 of the second web 40 therefore does not extend along the entire width b1 (see FIG. 1B) of the material web 40.

The pressure-sensitive adhesive 22 has, in all the respective embodiments, a composition which has a low adhesive effect. As a result, both the adhesion to the front side 6.3 of the first web 6 and the connection to the liquid seal 4, sealing slurry 4, tile adhesive or mortar 8 are not particularly strong. As soon as transverse forces occur, either the liquid seal 4, sealing slurry 4, the tile adhesive or mortar 8 will come off the pressure-sensitive adhesive 22, or the pressure-sensitive adhesive 22 will detach on its back from the first web 6. In any event, it will become necessary the elastic base material of the web 6 is released and the first web 6 can stretch at least in the transverse direction. The use of such a pressure-sensitive adhesive 22 leads to the temporary reduction of the extensibility of the elastic base material in the region of the expansion zone DZ.

As a pressure-sensitive adhesive, which is also referred to as a temporary adhesive, as a non-permanent adhesive or as a removable adhesive, in all embodiments, e.g. an acrylate-based or rubber-based adhesive.

Preferably, the pressure-sensitive adhesive, which is used according to the invention in all embodiments, a low shear strength, since it should peel off when occurring lateral forces.

Preferably, the pressure-sensitive adhesive used according to the invention in all embodiments has an adhesion capacity which is lower than the cohesive strength, so that the adhesion decreases when transverse forces occur.

FIG. 3B (as well as FIG. 1C) shows an approach based on the use of a flexible strip of material 21 (eg, a foil, a cut protection strip, or an adhesive strip) that temporarily adheres to the first panel 6 by means of a pressure sensitive adhesive 22. FIG , Again, the use of such a pressure sensitive adhesive 22 together with the flexible material strip 21 for temporary reduction or even cancellation of the elasticity of the elastic base material in the region of the expansion zone DZ. As soon as transverse forces occur, either the liquid seal 4, sealing slurry 4, the tile adhesive or mortar 8 will come off the flexible material strip 21 or the pressure sensitive adhesive 22 will come off between the flexible strip of material 21 and the first web 6.

FIG. 3C shows an approach based on the use of an impregnation 23. As impregnation 23, a material or combination of materials is selected which on the one hand connects to the first web 6, but which on the other hand, however, reduces the adhesion to liquid seal 4, sealing slurry 4, tile adhesive and mortar 8.

In all embodiments, a non-stick coating can be used as the impregnation 23, wherein the non-stick properties are selected to be effective in the liquid seal 4, sealing slurry 4, tile adhesive and mortar 8 to be used.

An impregnation 23 based on silicone or Teflon is particularly suitable. Also suitable are fatty impregnations 23.

Particularly suitable impregnations 23, which can be applied liquid, so as to define the zone Z3, but after the order (hard) cure or dry, without losing the non-stick properties.

Further modifications of the invention are shown in FIGS. 3D to 3F and will be described only briefly below. Otherwise, the description of FIGS. 3A to 3C is also applicable to FIGS. 3D to 3F.

FIG. 3D shows an approach based on the use of a flexible strip of material 21 (eg a foil, a cut protection strip or an adhesive strip), which temporarily adheres to the first web 6 by means of a pressure-sensitive adhesive 22 (analogous to FIG. 3B). , In addition, a cut protection strip 24 is arranged in front of the material strip 21 on the room side, which in the case of FIG. 3D is connected to the strip 6 by means of an adhesive 25. The expansion zone DZ is here protected by the combination of strips of material 21 and cut protection strip 24, or defined.

FIG. 3E shows another approach based on the use of a flexible strip of material 21 (eg, a foil, a cut protection strip, or an adhesive strip) which temporarily adheres to the first web 6 by means of a pressure sensitive adhesive 22 (analogous to FIG. 3B) and 3D). In addition, a cut protection strip 24 is arranged in front of the material strip 21 on the room side, but here it is not connected / glued to the first web 6. The cut protection strip 24 is inserted here into a longitudinal gap, which results between the first web 6 and the second web 40. Since the cut protection strip 24 has a certain inherent rigidity, it can be easily inserted during assembly. This constellation is a standing constellation. The expansion zone DZ is here protected by the combination of strips of material 21 and cut protection strip 24, or defined.

FIG. 3F shows another approach based on the use of a flexible strip of material 21 (eg, a foil, a cut protection strip, or an adhesive strip) that temporarily adheres to the first web 6 by means of a pressure sensitive adhesive 22 (analogous to FIG. 3B) and 3D). In addition, a cut protection strip 24 is arranged in front of the material strip 21 on the room side (as in FIG. 3E), but here it is not connected / glued to the first web 6. The cut protection strip 24 is here inserted into a longitudinal gap or pocket 44 provided on the second panel 40, as shown. The expansion zone DZ is here protected by the combination of strips of material 21 and cut protection strip 24, or defined.

The method for creating a transition between a sanitary device 1 and an on-site vertical or horizontal surface 2 is preferably as follows: providing a length Lx of a device 5, comprising: a first extensible web 6 comprising a resilient base material and the extends parallel to a longitudinal axis x, • a second path 40 which extends parallel to the longitudinal axis x and along a (lower) Längsran-the 6.1 area on a side surface 6.3, 6.4 of the first.
