Description

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

There are transitions between sanitary facilities and walls in and around buildings in the damp or wet area, which are usually produced today with connection tapes.

Over time, settlement phenomena may occur in which cracks may form in the area 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 band of 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 tapes is usually complicated and the tapes are therefore expensive. In addition, the installation of such connection tapes is not always easy.

The object is 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.

• - eine erste dehnbare Bahn, die ein elastisches Basismaterial umfasst und die sich parallel zu der Längsachse erstreckt,
• - eine zweite Bahn, die sich parallel zu der Längsachse erstreckt und die entlang eines Längsrandes flächig an einer Seitenfläche der ersten Bahn angeordnet und mit dieser verbunden ist, um eine erste streifenförmige Zone der Vorrichtung zu definieren, wobei die Vorrichtung einen zweiten streifenförmigen Bereich der ersten Bahn aufweist, der sich parallel zu der Längsachse erstreckt und der dadurch definiert ist, dass die ersten Bahn in diesem streifenförmigen Bereich mit einer Schutzschicht versehen ist, um so eine Dehnzone zu definieren.

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 and extending parallel to the longitudinal axis,
• a second web extending parallel to the longitudinal axis and being arranged along a longitudinal edge flat on a side surface of the first web and connected thereto to define a first strip-shaped zone of the device, the device comprising 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 is provided in this strip-shaped region with a protective layer so as to define a Dehnzone.

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

The second web may be bonded to the first web in all embodiments by gluing, vulcanizing, fusing, or pressing.

The second panel may be connected to the first panel by stitching or pinning in all embodiments.

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

The first web should preferably have a modulus of elasticity (modulus of elasticity) less 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 apparatus of the invention can be used in all embodiments to provide for a transition between a vertical surface (frame) of a sanitary device and an on-site vertical surface (eg a wall) or for a transition between a vertical surface (frame) of a sanitary device and an on-site Horizontal surface (eg a floor) to provide.

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

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

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

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 comprise a metallic material (eg, a CNS foil or a CNS lattice or mesh) and / or a plastic material (eg, a high strength polyethylene) and / or a composite material (eg, a nonwoven or aramid and woven fabric) 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 distinguished in all embodiments not only by a sufficiently high cut resistance but also by a high puncture resistance.

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

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 a cut protection strip is a metal lattice structure, a plastic lattice structure, a fabric lattice structure or a fiber lattice 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 which is flexible in the plane or at least manually bendable. 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 "strip" are intended to indicate that the geometry extends in one direction, the so-called "strip longitudinal direction" or "strip length", while the width and thickness of the strip measured perpendicularly thereto are smaller.

The width of the device of the invention may for example be 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 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).

In all embodiments, the protective layer can already be connected ex works to the first web 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, the protective layer in all embodiments 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., a wall or floor).

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 narrow down the location and direction information, in part, a reference to the wall 2 (also vertical surface 2 mentioned) in which, for example, from a wall-near element, a wall facing, wall facing away from the surface or a wall-parallel assembly is mentioned.

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

It's about devices 5 (Also referred to as sealing or connecting band), which can serve, for example, to a tight transition in the connection area between a bathtub, or other sanitary device 1 , and a wall surface or floor surface 2 to accomplish. A corresponding example is in 4 shown. 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 that runs parallel to a longitudinal axis x and through a strip width b that runs parallel to a transverse axis y. The stripe width b runs perpendicular to the longitudinal axis x, as you eg in 1A can recognize.

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

The strip length Lx defines with the perpendicular stripe width b a plane E (xy plane). In 1C the plane E is indicated by a dashed line. In the pictures after 1A and 1B the plane E is in the drawing plane.

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

The devices 5 of the invention include in all embodiments a first extensible web 6 an 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.

In all embodiments, it is also possible to use a plastic fleece, fabric, grid, or net which is coated, laminated, or covered with plastic, thus forming a first extensible web 6 to obtain. 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).

Especially the Querdehnbarkeit is of great importance, as it is between the sanitary device 1 and the vertical surface 2 (eg a wall 2 ) to subsidence phenomena and in the range of expansion joints to expansion movements can come. For example, in the course of time drying processes, temperature fluctuations and other processes can lead to a bathtub 1 by a few millimeters from a wall next to it 2 emotional.

Therefore, the device 5 The invention preferably in all embodiments designed to compensate for such settlement movements and stretching movements or record. A device 5 Therefore, the invention has a stretch zone DZ, which in all embodiments, a Querdehnbarkeit, preferably in the range between 1mm and 2cm, allows.

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

The extensibility is preferably in the region of the expansion zone DZ 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, in all embodiments, has a modulus of elasticity that is less than 100 N / mm ² . Particularly preferably, the modulus of elasticity in all embodiments is less than 10 N / mm ² .

To the first train 6 safely and firmly with other materials and / or layers to a ready to install device 5 to be able to put together has the first track 6 in all embodiments, preferably a side surface (here the front side 6.3 ), which has good adhesion or bonding properties. The meaning of this aspect of the invention may be particularly well described by comparison with a rubbery, smooth material (such as a bicycle tube). A rubbery, smooth material typically has high elasticity (ie, 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. For example, the surface of the bicycle hose must first be roughened in order to be able to vulcanize a patch, for example.

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

For this purpose, the side surface 6.3 / can the side surfaces 6.3 . 6.4 the first track 6 in all embodiments, for example, have a net, fabric, fleece or fibrous 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 essentially preserved. That is, the net, fabric, fleece or fibrous surface itself must also be stretchable.

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

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

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

This second train 40 runs along a longitudinal edge 6.1 the first material web 6 , as in 1B can be seen. The second train 40 can be flush with the longitudinal edge in all embodiments 6.1 run, as in 1B . 1C . 2A . 3A . 3B . 3C . 3D . 3E and 3F shown, or it may be slightly above the longitudinal edge 6.1 run, as in 2 B shown, or she may be slightly below the longitudinal edge 6.1 run, as in 4 indicated.

The second train 40 can in all embodiments on a side surface 6.3 . 6.4 the first track 6 be arranged and connected to this, a first strip-shaped zone Z1 the device 5 define. The first strip-shaped zone Z1 is in the 1B . 2A . 2 B . 3A to 3F characterized by a curly bracket. In the figures, only embodiments are shown in which the second track 40 flat with the front 6.3 the first track 6 connected is. The second train 40 but in all embodiments also flat with the back 6.4 the first track 6 be connected, or it can both be a train 40 on the front side 6.3 and another track on the back 6.4 be arranged.

The following aspect is related to the second lane 40 significant. By doing that the second lane 40 with the elastic base material of the first web 6 is connected, the elasticity, respectively the extensibility of the first web 6 significantly reduced. The first train 6 So is by connecting to the second track 40 in the area of the first strip-shaped zone Z1 stiffens, as far as the transverse and longitudinal extensibility is concerned.

Based on 2A and 2 B For example, two different approaches with respect to the second material web 40 described.

In 2A an embodiment is shown in which the material of the second web 40 intimately with the base material of the first track 6 connected is. In 2A is shown in schematic form that the first track 6 may have an open (surface) structure (eg a mesh-like, net-like, fabric-like, fleece-like or fibrous structure). If now the material of the second lane 40 is applied in liquid form, so penetrates this material (yes, according to viscosity) in spaces, holes, pores or meshes of the first web 6 one. This effect is in 2A illustrated in a purely schematic form. This type of connection is referred to here as an intimate connection.

An embodiment according to 2A can be prepared, for example, that butyl (eg from a Fassschmelzanlage) in viscous form in the area Z1 on the first track 6 is applied. The result is an intimate connection, which, after curing, the first track 6 in the zone Z1 the elasticity decreases. Analogously, also strip goods can be applied.

In 2 B an embodiment is shown in which the material of the second web 40 eg by means of an adhesive 43 with the base material of the first track 6 connected is. In 2 B is again shown in schematic form that the first orbit 6 may have an open structure, as already mentioned. The glue 43 penetrates, depending on the selected texture of the adhesive 43 , not or hardly in the first lane 6 one. This is a sandwich-type compound. Nevertheless, this will make the zone Z1 almost dimensionally stable.

In one embodiment according to 2 B This may be the material of the second web 40 For example, to act as a foam, as a sound decoupling between the sanitary device 1 and the wall or the floor 2 can serve.

In the 2A and 2 B is further indicated that an optional protective film or a protective paper 41 can be used to the second lane 40 temporarily (until the time of installation) to protect. The use of an optional protective film or an optional protective paper 41 makes sense especially if it is the train 40 an adhesive material (eg butyl), or if the web 40 room side with a glue 42 (please refer 2 B) is covered. In 1A is also a short section of an optional protective film or protective paper 41 shown.

The devices 5 of the invention include in all embodiments in addition to the first web 6 and the second track 40 a second strip-shaped area, denoted by the reference numeral Z3 is provided. This second strip-shaped area Z3 is right next to the first track 6 provided / defined.

The second strip-shaped area Z3 extends in all embodiments in turn parallel to the x-axis. Furthermore, it has a transverse dimension, width b2 in 1B which is perpendicular to the x-axis.

The second strip-shaped area Z3 may in all embodiments immediately above the second track 40 start as in 1B shown, or he may be a small distance to the second web 40 to have. However, it is also possible in all embodiments that the second strip-shaped area Z3 and the second track 40 overlap a bit, as in 3A indicated.

To the meaning and purpose of this second strip-shaped area Z3 In the following, we will briefly discuss the situation in the assembled state. In this context, especially on 4 Referenced. In this figure, an exemplary installation situation is shown in an exploded view.

The device 5 is, as already mentioned, especially for creating a transition between a fixed-mounted device 1 (here a bathtub) and an on-site area 2 (here a vertical wall section 2 ) designed. The device 5 includes the first track 6 which is a band along a longitudinal axis Lx extends, how to eg 1A can take. The longitudinal axis Lx is perpendicular to the plane of the drawing 4 ,

The first train 6 is designed in the embodiment shown to be arranged wall-parallel in the assembled state, as in 4 shown. The first train 6 becomes in a strip-shaped area Z2 (please refer 1A) with the wall 2 connected. In 4 is a liquid seal or sealing slurry 4 shown by two dashed lines. The liquid seal or sealing slurry 4 Can on the front of the wall 2 be applied before the first train 6 with its strip-shaped area Z2 into the liquid seal or sealing slurry 4 is inserted. Then, to improve the adhesion and sealing effect, another layer of the liquid seal or the sealing slurry 4 over the strip-shaped area Z2 be applied. This type of connection is referred to herein as embedding, preferably in the area Z2 both sides of the first track 6 intimately with the liquid seal or the sealing slurry 4 are connected. If the first train 6 open / continuous (eg by providing cutouts or if the base material has open mesh, mesh, mesh or fabric areas), then the base material may be from the liquid seal or from the sealing slurry 4 be penetrated.

It therefore comes with the assembly in the zone Z2 to a stiffening of the originally elastic material of the first web 6 ,

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

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

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

The first train 6 can in all embodiments also with an adhesive with the surface 2 or a separate strip of material (eg, an adhesive strip) may be attached to the zone Z2 overlaps the web 6 with the area 2 connect to.

Finally, the first track 6 in the zone Z2 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, protective layer or protection zone 20 , either the extensibility of the first orbit 6 received during and after assembly, or the first track 6 becomes in the strip-shaped area Z3 so covered or protected that the extensibility can be effective in the event of lateral forces (in the case of subsidence movements), even if it was temporarily impaired (eg due to careless or inappropriate assembly).

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

3A shows an approach based on the use of a pressure-sensitive adhesive 22 based. This adhesive 22 serves as a protective strip or protective layer of the expansion zone DZ , As in 3A It can be seen, this pressure-sensitive adhesive 22 optionally a little way under the second lane 40 extend. The glue 43 the second track 40 therefore does not extend along the full width b1 (please refer 1B) the material web 40 ,

The pressure-sensitive adhesive 22 has in all the respective embodiments, a composition which has a low adhesive effect. This is both the adhesion to the front 6.3 the first track 6 as well as the connection with liquid seal 4 , Sealing slurries 4 Tile adhesive or mortar 8 not particularly strong. As soon as it comes to shear forces, either the liquid seal will 4 , Sealing slurries 4 , the tile adhesive or mortar 8 from the pressure-sensitive adhesive 22 peel off, or the pressure-sensitive adhesive 22 dissolves on its back from the first track 6 , In any case, then, if necessary, the elastic base material of the web 6 released and the first track 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.

3B (as well as 1C) shows an approach based on the use of a flexible strip of material 21 (For example, a foil, a cut protection strip or an adhesive strip), which by means of a pressure-sensitive adhesive 22 temporarily at the first track 6 liable. Again, the use of such a pressure sensitive adhesive 22 together with the flexible material strip 21 for the temporary reduction or even cancellation of the extensibility of the elastic base material in the region of the expansion zone DZ , As soon as it comes to shear forces, either the liquid seal will 4 , Sealing slurries 4 , the tile adhesive or mortar 8th from the flexible strip of material 21 peel off, or the pressure-sensitive adhesive 22 dissolves between the flexible strip of material 21 and the first track 6 ,

3C shows an approach based on the use of an impregnation 23 based. As impregnation 23 a material or combination of materials is selected, which on the one hand with the first track 6 combines, on the other hand, however, to reduce the adhesion to liquid seal 4 , Sealing slurries 4 Tile adhesive and mortar is 8.

In all embodiments, a non-stick coating may be used as impregnation 23 can be used, wherein the non-stick properties are chosen so that they in the liquid seal to be used 4 , Sealing slurries 4 , Tile adhesive and mortar 8th is effective.

Particularly suitable is an impregnation 23 on silicone or Teflon-based. Also suitable are fatty impregnations 23 ,

Particularly suitable impregnations 23 , which can be applied liquid, so the zone Z3 but after application they harden (dry) or dry without losing the non-stick properties.

Further modifications of the Erfung are in the 3D to 3F are shown and are only briefly described below. Otherwise, the description of the 3A to 3C also on the 3D to 3F applicable.

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

3E shows another approach based on the use of a flexible strip of material 21 (For example, a foil, a cut protection strip or an adhesive strip), which by means of a pressure-sensitive adhesive 22 temporarily at the first track 6 liable (analogous to 3B and 3D) , In addition, the room side is in front of the material strip 21 a cut protection strip 24 arranged here but not with the first track 6 is connected / glued. The cut protection strip 24 is inserted here in a longitudinal gap, which is between the first track 6 and the second track 40 results.
