The present invention relates to a material tape system, a material tape system assembly, a method for producing a material tape system assembly and use of a material tape system.

Material tape systems are known from the prior art. The material tape systems have a backing tape, which has a first end section and a second end section and extends from the first end section to the second end section. It is possible, for example, for self-adhesive punched parts to be arranged on the backing tape, and for them to be successively detached from the backing tape and applied to surfaces of products in an automated process.

It is generally desirable to provide material tape systems which simplify handling, ensure time-efficient and resource-saving processes and increase process stability and process reliability.

It is therefore the object of the present invention to simplify handling, to ensure time-efficient and resource-saving processes and to increase process stability and process reliability.

According to a first aspect of the invention, the stated object is achieved by a material tape system having the features of Patent claim1. The material tape system has a backing tape. The backing tape has a first end section and a second end section. The backing tape extends from the first end section to the second end section. The material tape system has a fixing adhesive tape. The fixing adhesive tape system has a fixing adhesive surface. By means of the fixing adhesive surface, the fixing adhesive tape is detachably connected to the first end section of the backing tape on a first side of the backing tape. The material tape system has a first connecting adhesive tape. The first connecting adhesive tape has a connecting section. By means of the connecting section, the first connecting adhesive tape is connected to the first end section of the backing tape on a second side of the backing tape, which is opposite to the first side of the backing tape. The fixing adhesive tape and the first connecting adhesive tape are connected to the backing tape in such a way that, when the fixing adhesive tape is connected to the backing tape, a connecting adhesive surface of the first connecting adhesive tape is covered, and, when the fixing adhesive tape is detached from the backing tape, the connecting adhesive surface of the first connecting adhesive tape is exposed.

The material tape system has the backing tape. The backing tape has the first end section and the second end section and extends from the first end section to the second end section. The first end section preferably has a first end face. The second end section preferably has a second end face. In particular, the backing tape extends from the first end section to the second end section in a backing tape direction of extent. The first end face is preferably arranged opposite to the second end face in the backing tape direction of extent in such a way that the first end face and the second end face point in opposite directions. The backing tape can have a release layer, which can be a release paper. Furthermore, the backing tape can have a backing layer connected to the release layer. The release layer preferably has a surface, facing away from the backing layer, with a section to which, in particular, pressure-sensitive adhesive surfaces can be connected and from which these pressure-sensitive adhesive surfaces can be detached particularly easily. A multiplicity of, in particular self-adhesive, punched parts can be arranged on this section of the surface of the release layer, for example. The backing layer ensures that the backing tape is of mechanically robust design in its main plane of extent, in particular with respect to tensile loads in the main plane of extent. The release layer can be arranged on the first side of the backing tape. Alternatively, the release layer can also be arranged on the second side of the backing tape. In a further alternative, the backing tape has only the release layer, and in particular no backing layer. The backing layer can be arranged on the second side of the backing tape. Alternatively, the backing layer can also be arranged on the first side of the backing tape. In the event that both the release layer and the backing layer are provided, it is possible, when the release layer is arranged on the first side of the backing tape and the backing layer is arranged on the second side of the backing tape, for the backing tape to provide the functionality of the release layer on the first side and the functionality of the backing layer on the second side. If the release layer is arranged on the second side of the backing tape and the backing layer is arranged on the first side of the backing tape, the backing tape can provide the functionality of the release layer on the second side and the functionality of the backing layer on the first side. The backing tape can be wound around a roll core of the material tape system.

The material tape system has the fixing adhesive tape. The fixing adhesive tape preferably has a backing layer and an adhesive layer. The backing layer ensures that the fixing adhesive tape is of mechanically robust design in its main plane of extent, in particular with respect to tensile loads in the main plane of extent. The adhesive layer is preferably connected to the backing layer. The adhesive layer is preferably pressure-sensitive. The pressure-sensitive adhesiveness of the adhesive layer ensures that the fixing adhesive tape can be connected to other elements, such as, for example, to the first end section of the backing tape or to a release tape or both to the first end section and to the release tape. The fixing adhesive tape has the fixing adhesive surface. By means of the fixing adhesive surface, the fixing adhesive tape is detachably connected to the first end section of the backing tape on the first side of the backing tape. The detachable connection between the fixing adhesive surface of the fixing adhesive tape and the first end section of the backing tape ensures that the fixing adhesive tape is connected to the backing tape and can be detached therefrom. The fixing adhesive tape is preferably detachably connected by means of the fixing adhesive surface on the first side of the backing tape to a section of the release layer of the backing tape on the first end section of the backing tape. In particular, the detachable connection between the fixing adhesive surface of the fixing adhesive tape and the section of the release layer of the backing tape ensures that the fixing adhesive tape and the backing tape can be detached from one another particularly easily, in particular when the connection between the fixing adhesive surface of the fixing adhesive tape and the section of the release layer of the backing tape is to be broken.

The connection between the fixing adhesive tape and the backing tape ensures that the backing tape can be connected with the aid of the fixing adhesive tape to, for example, the roll core of the material tape system or to a section of the backing tape, in particular on the first side of the backing tape, particularly when the backing tape is wound around the roll core. In the wound state, the backing tape can thus be connected to itself with the aid of the fixing adhesive tape, ensuring that the backing tape remains in the wound state. The detachment of the fixing adhesive tape from the backing tape ensures that the backing tape can be decoupled from the roll core of the material tape system or from the section of the backing tape, in particular on the first side of the backing tape, and in the process or subsequently the fixing adhesive tape can be detached from the backing tape. The detachable connection between the fixing adhesive tape and the backing tape ensures that the function of connecting the backing tape, for example to the roll core of the material tape system or to the section of the backing tape, in particular on the first side of the backing tape, can be fulfilled by the fixing adhesive tape and that the structural make up of the backing tape can be chosen independently of this function.

The adhesive layer of the fixing adhesive tape can form an adhesive surface which has a plurality of sections. A first section of the plurality of sections of the adhesive surface of the adhesive layer of the fixing adhesive tape can form the fixing adhesive surface by means of which the fixing adhesive tape is detachably connected to the first end section of the backing tape. A second section of the plurality of sections of the adhesive surface of the adhesive layer of the fixing adhesive tape preferably forms an adhesive surface by means of which the fixing adhesive tape can be detachably connected, for example, to the roll core of the material tape system or to a section of the backing tape, in particular on the first side of the backing tape. The second section can be exposed, in particular when the fixing adhesive tape is not detachably connected to the roll core of the material tape system or to a section of the backing tape, in particular on the first side of the backing tape. Furthermore, a third section of the plurality of sections of the adhesive surface of the adhesive layer of the fixing adhesive tape is preferably provided. The third section is preferably arranged between the first section and the second section. The third section is preferably covered by the release tape. The fixing adhesive tape can have a connecting section.

The material tape system has the first connecting adhesive tape. The first connecting adhesive tape preferably has a backing layer and an adhesive layer. The backing layer ensures that the first connecting adhesive tape is of mechanically robust design in its main plane of extent, in particular with respect to tensile loads in the main plane of extent. The adhesive layer can be connected to the backing layer. The adhesive layer is preferably pressure-sensitive. The pressure-sensitive adhesiveness of the adhesive layer ensures that the first connecting adhesive tape can be connected to other elements, such as, for example, to the first end section of the backing tape or to the release tape or both to the first end section and to the release tape.

The adhesive layer of the first connecting adhesive tape preferably forms an adhesive surface which has a plurality of sections. A first section of the plurality of sections of the adhesive surface of the adhesive layer of the first connecting adhesive tape preferably forms a connecting adhesive surface of the first connecting adhesive tape, which can be covered by the release tape. A second section of the plurality of sections of the adhesive surface of the adhesive layer of the first connecting adhesive tape, said second section being adjacent to the first section, preferably forms an adhesive surface by means of which the first connecting adhesive tape is connected to the first end section of the backing tape.

The first connecting adhesive tape has the connecting section. By means of the connecting section, the first connecting adhesive tape is connected to the first end section of the backing tape on the second side of the backing tape, which is opposite to the first side of the backing tape The connection between the connecting section of the first connecting adhesive tape and the first end section of the backing tape ensures that, when the first connecting adhesive tape is connected to a further element, the backing tape is connected to this further element via the first connecting adhesive tape. The connection between the connecting section of the first connecting adhesive tape and the first end section of the backing tape can be ensured by an adhesive surface formed by the second section of the plurality of sections of the adhesive surface of the adhesive layer of the first connecting adhesive tape, by means of which the first connecting adhesive tape is connected to the first end section of the backing tape.

The fixing adhesive tape and the first connecting adhesive tape are connected to the backing tape in such a way that, when the fixing adhesive tape is connected to the backing tape, the connecting adhesive surface of the first connecting adhesive tape is covered. In this case, the connecting adhesive surface can be covered by the release tape. Thus, when the fixing adhesive tape is connected to the backing tape, the connecting adhesive surface of the first connecting adhesive tape is covered, ensuring that when the material tape system is used, the first connecting adhesive tape does not adhere by means of the connecting adhesive surface to objects to which it is not intended to adhere. Furthermore, when the connecting adhesive surface of the first connecting adhesive tape is covered, the connecting adhesive surface is protected from contamination while using the material tape system.

The fixing adhesive tape and the first connecting adhesive tape are connected to the backing tape in such a way that, when the fixing adhesive tape is detached from the backing tape, the connecting adhesive surface of the first connecting adhesive tape is exposed. Owing to the fact that, when the fixing adhesive tape is detached from the backing tape, the connecting adhesive surface of the first connecting adhesive tape is exposed, it is possible, by detaching the fixing adhesive tape from the backing tape, to selectively expose the connecting adhesive surface in order to connect it selectively to other elements, such as, for example, to a connecting adhesive surface of a second connecting adhesive tape of another material tape system or to the second end section of the backing tape of the other material tape system on the second side of the backing tape of the other material tape system or both to the connecting adhesive surface of the second connecting adhesive tape of the other material tape system and to the second end section of the backing tape of the other material tape system on the second side of the backing tape of the other material tape system.

In particular, the material tape system ensures a plurality of functions by virtue of its construction and, in particular, by virtue of the fixing adhesive tape and the interaction of the fixing adhesive tape with the other elements of the material tape system. First, the backing tape can be detachably attached to further elements, such as, for example, to a roll core of the material tape system, with the aid of the fixing adhesive tape. Furthermore, the structural make up of the backing tape can be selected independently of the function of detachable attachment of the backing tape to further elements. This enables the backing tape to be of particularly flexible design in terms of its intended use. For example, the backing tape can be designed to be particularly light and at the same time mechanically robust, in particular tear-resistant. Moreover, the construction of the material tape system and, in particular, the fixing adhesive tape ensures the selective covering and exposure of the connecting adhesive surface of the first connecting adhesive tape, ensuring, on the one hand, that it is protected from contamination and, on the other hand, that it can be exposed when required. The material tape system thus ensures that the backing tape can be of mechanically robust design and that the use of the material tape system is particularly user-friendly. The user-friendliness is ensured, in particular, by the fact that the connecting adhesive surface can be exposed in a simple manner by detaching the fixing adhesive tape from the backing tape.

As already indicated, the material tape system, which can also be referred to as the first material tape system, can be connected to a further material tape system, which can also be referred to as the second material tape system. If at least two material tape systems are connected to one another, this assembly can also be referred to as a material tape system assembly. In particular, it is envisaged that, in the first material tape system, the fixing adhesive tape is first detached from the backing tape, with the result that the connecting adhesive surface of the first connecting adhesive tape is exposed, and then the first material tape system is connected to the second material tape system. Thus, in the material tape system assembly, at least the first material tape system has the fixing adhesive tape detached from the backing tape. This circumstance can also be designated in such a way that the first material tape system in the material tape system assembly has no fixing adhesive tape. In particular, the first material tape system and the second material tape system are connected to one another in such a way that the connecting adhesive surface of the first connecting adhesive tape of the first material tape system is connected to the second end section of the backing tape of the second material tape system on a second side of the backing tape of the second material tape system. Connecting a first material tape system to a second material tape system can also be referred to as splicing. In particular, the backing tape of the first material tape system can be connected to the backing tape of the second material tape system by connecting the first material tape system to the second material tape system.

As a result of the construction of the material tape system according to the invention, in particular as a result of the special connection of the fixing adhesive tape and of the first connecting adhesive tape to the backing tape, the material tape system can be used in a material tape system assembly in a simple and time-saving manner since all that is necessary to connect two material tape systems is to detach the fixing adhesive tape from the backing tape, and a simple connection possibility is thereby provided by the connecting adhesive surface of the first connecting adhesive tape. Particularly when a multiplicity of material tape systems is connected to one another in a material tape system assembly in such a way that each pair of adjacent material tape systems has a first material tape system and a second material tape system, wherein the connecting adhesive surface of the first connecting adhesive tape of the first material tape system is connected to the second end section of the backing tape of the second material tape system on a second side of the backing tape of the second material tape system, the simple connection of the material tape systems is particularly advantageous and the time saving potential is particularly pronounced. By virtue of the construction of the material tape system according to the invention, it is possible in particular to connect a plurality of backing tapes to one another particularly quickly. In particular, the material tape system according to the invention ensures simple handling since no additional material has to be provided for connecting a plurality of backing tapes since the connecting adhesive surface of the first connecting adhesive tape is already provided by the material tape system. This is advantageous particularly in comparison with material tape systems known from the prior art, which have a backing tape but no connecting adhesive tape according to the invention since it is often necessary in this case to provide additional adhesive tapes to connect backing tapes.

The following advantages have been found, particularly when using a material tape system in an automated robot applicator.

By virtue of the simple handling and time-saving connection of a plurality of material tape systems, the material changing times, in particular the time period between the use of a first material tape system and a second material tape system, have been significantly reduced since, when the backing tape of a first material tape system is unwound from the roll core of the first material tape system, the roll core of the first material tape system can be removed from the robot applicator, the roll core of the second material tape system can be inserted into the robot applicator, and the backing tape of the first material tape system can be connected to the backing tape of the second material tape system simply and quickly. It is thereby possible to accelerate and improve the efficiency of automated processes with automated robot applicators.

Furthermore, it has proven possible, with the aid of the material tape system according to the invention, to significantly increase process stability, particularly when used in an automated robot applicator since the material tape system according to the invention, particularly in a material tape system assembly, can be guided through a guide of the automated robot applicator in a manner which is consistent and predictable over time. In particular, the high process stability is ensured by the fact that the backing tapes of two adjacent material tape systems of a material tape system assembly can be positioned in a particularly precise manner with respect to one another. The particularly precise positioning of the backing tapes is ensured, in particular, by the first connecting adhesive tape, which is already attached to one end of a backing and has only to be connected to the second backing tape. It has been found that an operator of the automated robot applicator positions two backing tapes of two material tape systems according to the invention much more precisely with respect to one another than is the case with material tape systems known from the prior art.

Furthermore, it has been found that, with the aid of the material tape system according to the invention, process reliability, particularly when used in an automated robot applicator, could be significantly increased since the connection of two backing tapes of two material tape systems according to the invention is mechanically much more robust than is the case in the prior art. In particular, it has been found that two backing tapes of two material tape systems according to the invention are much more difficult to detach from one another than is the case in the prior art.

Furthermore, it has been found that when a plurality of material tape systems according to the invention with a roll core are used in a robot applicator, if the backing tape of a first material tape system of the plurality of material tape systems has already been unwound from the roll core but is still connected thereto, the robot applicator can be stopped, the backing tape of the first material tape system can be connected to the backing tape of the second material tape system of the plurality of material tape systems, and the robot applicator can then be started again, thus ensuring that the backing tape of the second material tape system is unwound from the roll core. By virtue of this procedure, it is possible, when using a multiplicity of material tape systems, to produce a continuous backing tape which has a multiplicity of backing tapes. With each connection of two backing tapes to produce the continuous backing tape, it is possible to use the total length of each backing tape, and thus, for example, also the total number of punched parts arranged on the backing tape, thereby making it possible to save material in comparison with the method known from the prior art, in particular through the use of all of the punched parts. Thus, particularly resource-saving methods are made possible with the aid of the material tape system according to the invention. Moreover, with each connection of two backing tapes to produce the continuous backing tape, it is possible to dispense with rethreading of the material tape system into the robot applicator, and therefore particularly time-efficient methods are made possible.

In summary, it can therefore be stated that the material tape system according to the invention simplifies handling, ensures time-efficient and resource-saving processes and increases process stability and process reliability.

In one embodiment, the material tape system has a release tape having a first side and a second side, wherein, when the fixing adhesive tape is connected to the backing tape, the release tape is arranged between the fixing adhesive tape and the first connecting adhesive tape in such a way that the fixing adhesive surface faces the first side of the release tape and the connecting adhesive surface faces the second side of the release tape. The release tape preferably has a release layer. The release layer can be a release paper. Furthermore, the release tape can have a backing layer. The backing layer is preferably connected to the release layer. The release layer preferably has a surface facing away from the backing layer, to which surface it is possible, in particular, to connect pressure-sensitive adhesive surfaces, such as, for example, the connecting adhesive surface of the first connecting adhesive tape, and from which these pressure-sensitive adhesive surfaces can be detached particularly easily. In particular, the backing layer ensures that the release tape is of mechanically robust design in its main plane of extent, in particular with respect to tensile loads in the main plane of extent. Furthermore, the release tape preferably has a first side and a second side. The backing layer is preferably arranged on the first side of the backing tape. The release layer is preferably arranged on the second side of the release tape. In particular, the release tape is arranged between the fixing adhesive tape and the first connecting adhesive tape. The release tape preferably rests against the first end face of the first end section and thereby covers the latter, thus ensuring that the first end face is protected from mechanical effects, such as, for example, elastic or plastic deformations of the first end face, such as, for example, cracks in the first end face. As already described, the fixing adhesive tape is connected to the backing tape. In this case, the release tape is preferably arranged between the fixing adhesive tape and the first connecting adhesive tape in such a way that the first section, which forms the fixing adhesive surface of the fixing adhesive tape, the second section and the third section of the plurality of sections of the adhesive surface of the adhesive layer of the fixing adhesive tape face the first side of the release tape. Here, the third section of the plurality of sections of the adhesive surface of the adhesive layer of the fixing adhesive tape is preferably covered by the release tape. In particular, the release tape is arranged between the fixing adhesive tape and the first connecting adhesive tape in such a way that the connecting adhesive surface of the first connecting adhesive tape faces the second side of the release tape. The connecting adhesive surface of the first connecting adhesive tape is preferably covered by the release tape.

In one embodiment, the release tape is connected on its first side to the fixing adhesive tape and is detachably connected on its second side to the connecting adhesive surface of the first connecting adhesive tape in such a way that, when the fixing adhesive tape is detached from the backing tape, the release tape is detached from the connecting adhesive surface. Owing to the fact that the release tape is connected on its first side to the fixing adhesive tape and is detachably connected on its second side to the connecting adhesive surface of the first connecting adhesive tape in such a way that, when the fixing adhesive tape is detached from the backing tape, the release tape is detached from the connecting adhesive surface, the connecting adhesive surface can be exposed by removing the fixing adhesive tape and thereby removing the release tape. Exposure of the connecting adhesive surface can thus also be ensured in the case where a release tape is provided.

In one embodiment, the connecting adhesive surface of the first connecting adhesive tape is covered by the release tape. The covering of the connecting adhesive surface of the first connecting adhesive tape by the release tape ensures that the connecting adhesive surface is protected with the aid of the release tape, in particular from contamination. The release tape is preferably designed, arranged and connected to the fixing adhesive tape in such a way that, when the fixing adhesive tape is connected to the backing tape, the connecting adhesive surface of the first connecting adhesive tape is directly covered by the release tape, i.e. the latter rests against the connecting adhesive surface and completely covers it.

In one embodiment, a first adhesive force acting from the fixing adhesive surface to the backing tape is less than a second adhesive force acting from a connecting section of the fixing adhesive tape to the release tape. The second adhesive force preferably acts from the third section of the plurality of sections of the adhesive surface of the adhesive layer of the fixing adhesive tape to the release tape. The first and second adhesive forces are preferably to be understood to mean a force threshold which must be overcome in order to detach the corresponding elements from one another under a load perpendicular to the connecting surfaces of the individual elements. The first adhesive force is preferably a force threshold which must be overcome in order to detach the backing tape and the fixing adhesive tape from one another, and the second adhesive force is a force threshold which must be overcome in order to detach the fixing adhesive tape and the release tape from one another.

In one embodiment, the second adhesive force acting from the connecting section of the fixing adhesive tape to the release tape is greater than a third adhesive force acting from the connecting adhesive surface of the first connecting adhesive tape to the release tape. The third adhesive force is preferably to be understood to mean a force threshold which must be overcome in order to detach the corresponding elements from one another under a load perpendicular to the connecting surfaces of the individual elements. The third adhesive force is preferably a force threshold which must be overcome in order to detach the first connecting adhesive tape and the release tape from one another.

In one embodiment, the third adhesive force acting from the connecting adhesive surface of the first connecting adhesive tape to the release tape is less than a fourth adhesive force acting from the connecting section of the first connecting adhesive tape to the first end section of the backing tape. The fourth adhesive force is preferably to be understood to mean a force threshold which must be overcome in order to detach the corresponding elements from one another under a load perpendicular to the connecting surfaces of the individual elements. The fourth adhesive force is preferably a force threshold which must be overcome in order to detach the first connecting adhesive tape and the backing tape from one another.

The material tape system is preferably designed in such a way that, when the material tape system is subjected to a tensile load perpendicular to the connecting surfaces of the individual elements, in that a tensile force acts on the fixing adhesive tape and an oppositely acting tensile force acts on the first connecting adhesive tape, both the backing tape and the fixing adhesive tape are detached from one another and the connecting adhesive tape and the release tape are detached from one another, wherein both the fixing adhesive tape and the release tape and also the backing tape and the first connecting adhesive tape remain connected to one another. This can be achieved, in particular, by matching the pressure-sensitive adhesiveness of the different pressure-sensitive adhesive surfaces to one another.

In particular, the pressure-sensitive adhesiveness of the different pressure-sensitive adhesive surfaces is matched to one another as follows. A first strength threshold value of the connection between the fixing adhesive surface and the backing tape is preferably lower than a second strength threshold value of the connection between the connecting section of the fixing adhesive tape and the release tape. In particular, the second strength threshold relates to the connection between the third section of the plurality of sections of the adhesive surface of the adhesive layer of the fixing adhesive tape and the release tape. Furthermore, the second strength threshold value of the connection between the connecting section of the fixing adhesive tape and the release tape is preferably higher than a third strength threshold value of the connection between the connecting adhesive surface of the first connecting adhesive tape and the release tape. Furthermore, the third strength threshold value of the connection between the connecting adhesive surface of the first connecting adhesive tape and the release tape is preferably lower than a fourth strength threshold value of the connection between the connecting section of the first connecting adhesive tape and the first end section of the backing tape. The first, second, third and fourth strength threshold values are preferably each to be understood to mean a strength threshold value which must be overcome in order to detach the corresponding elements from one another under a load perpendicular to the connecting surfaces of the individual elements and perpendicular to the first connecting adhesive tape direction of extent. The first strength threshold value is preferably a strength threshold value which must be overcome in order to detach the backing tape and the fixing adhesive tape from one another, the second strength threshold value is preferably a strength threshold value which must be overcome in order to detach the fixing adhesive tape and the release tape from one another, the third strength threshold value is preferably a strength threshold value which must be overcome in order to detach the first connecting adhesive tape and the release tape from one another, and the fourth strength threshold value is a strength threshold value which must be overcome in order to detach the first connecting adhesive tape and the backing tape from one another.

The features, technical effects and/or advantages described in connection with the first, second, third and fourth adhesive forces and in connection with the first, second, third and fourth strength threshold values preferably also apply, at least in an analogous manner, to a first, second, third and fourth peeling force, which describes the force threshold which must be overcome in order to pull one element off another element. For example, it is envisaged that when the outermost end of the fixing adhesive tape is initially pulled upwards perpendicularly to the connecting surfaces of the individual elements and perpendicularly to the first connecting adhesive tape direction of extent and then upwards and counter to the first connecting adhesive tape direction of extent, both the backing tape and the fixing adhesive tape as well as the connecting adhesive tape and the release tape are detached from one another owing to the ratios of the first, second, third and fourth peeling forces with respect to one another, wherein both the fixing adhesive tape and the release tape as well as the backing tape and the first connecting adhesive tape remain connected to one another.

In one embodiment, when the fixing adhesive tape is connected to the backing tape, the connecting adhesive surface of the first connecting adhesive tape is arranged on the first side of the backing tape. The first connecting adhesive tape is preferably folded around the first end section of the backing tape. The first connecting adhesive tape can be arranged in a U shape. The first connecting adhesive tape preferably encloses the first end section of the backing tape in such a way that the first end face is covered by the first connecting adhesive tape, thus ensuring that the first end face is protected by the first connecting adhesive tape. The third section of the plurality of sections of the adhesive surface of the adhesive layer of the fixing adhesive tape is preferably provided. In particular, the third section forms a pressure-sensitive adhesive surface, by means of which the fixing adhesive tape is connected to a surface of a section of the backing layer of the first connecting adhesive tape on the side of the backing layer of the first connecting adhesive tape. The surface of the section of the backing layer of the first connecting adhesive tape may itself not be of pressure-sensitive adhesive design. However, in comparison with the surface of the section of the release layer, the surface of the section of the backing layer of the first connecting adhesive tape is preferably designed in such a way that the material bond between the fixing adhesive tape and the first connecting adhesive tape is mechanically more robust than the material bond between the fixing adhesive tape and the backing tape. The material tape system preferably has no release tape when the fixing adhesive tape is connected to the backing tape and the connecting adhesive surface of the first connecting adhesive tape is arranged on the first side of the backing tape. It is thereby possible to provide a material tape system which makes particularly sparing use of resources.

In one embodiment, the first connecting adhesive tape extends in a first connecting adhesive tape direction of extent away from the first end section of the backing tape, wherein an extent of the connecting section of the first connecting adhesive tape in the connecting adhesive tape direction of extent corresponds to between 20% and 40%, preferably between 30 and 35%, of an extent of the first connecting adhesive tape in the connecting adhesive tape direction of extent. By virtue of the fact that the extent of the connecting section of the first connecting adhesive tape in the connecting adhesive tape direction of extent can correspond to between 20% and 40%, preferably between 30 and 35%, of an extent of the first connecting adhesive tape in the connecting adhesive tape direction of extent, it is possible to ensure both a mechanically robust overlapping connection between the backing tape and the first connecting adhesive tape and a sufficiently large connecting adhesive surface of the first connecting adhesive tape for mechanically robust connections. This effect is observable over a total range of 20% to 40% and is particularly pronounced in a range of 30% to 35%. It has surprisingly been found that, if the extent of the connecting section of the first connecting adhesive tape in the first connecting adhesive tape direction of extent corresponds to 33% of the extent of the first connecting adhesive tape in the first connecting adhesive tape direction of extent, the overlapping connection between the backing tape and the first connecting adhesive tape and the mechanically robust connections with the aid of the connecting adhesive surface of the first connecting adhesive tape can be matched to one another in a particularly advantageous manner.

In one embodiment, the material tape system has a roll core with a circumferential outer surface, wherein the fixing adhesive tape has a connecting section, by means of which the fixing adhesive tape is connected, in particular detachably, to the outer surface. By virtue of the fact that the fixing adhesive tape has the connecting section, by means of which the fixing adhesive tape is connected, in particular detachably, to the outer surface, the backing tape can be connected to the roll core by its first end section in such a way that, in the rolled-up state, the first end section of the backing tape is arranged radially inwardly in comparison with the second end section of the backing tape.

In one embodiment, the material tape system has a second connecting adhesive tape having a connecting section, by means of which the second connecting adhesive tape is connected to the second end section of the backing tape on the first side of the backing tape, and having a connecting adhesive surface. The second connecting adhesive tape preferably has a connecting section and a connecting adhesive surface. By means of the connecting section, the second connecting adhesive tape is connected to the second end section of the backing tape, preferably on the first side of the backing tape. The connection between the connecting section of the second connecting adhesive tape and the second end section of the backing tape ensures that, when the second connecting adhesive tape is connected to a further element, the backing tape is connected to this further element via the second connecting adhesive tape. The connection between the connecting section of the second connecting adhesive tape and the second end section of the backing tape can ensure, for example, that the backing tape can be connected with the aid of the second connecting adhesive tape to, for example, a roll core of the material tape system or to a section of the backing tape, in particular on the first side of the backing tape, particularly when the backing tape is wound around the roll core. The second connecting adhesive tape preferably has a backing layer and an adhesive layer. The backing layer ensures that the second connecting adhesive tape is of mechanically robust design in its main plane of extent, in particular with respect to tensile loads in the main plane of extent. The adhesive layer is connected, in particular, to the backing layer. The adhesive layer is preferably pressure-sensitive and thus ensures that the second connecting adhesive tape can be connected to other elements. The adhesive layer of the second connecting adhesive tape preferably forms an adhesive surface which has a plurality of sections. A first section of the plurality of sections of the adhesive surface of the adhesive layer of the second connecting adhesive tape preferably forms the connecting adhesive surface of the second connecting adhesive tape. A second section of the plurality of sections of the adhesive surface of the adhesive layer of the second connecting adhesive tape, said second section being adjacent to the first section, preferably forms an adhesive surface by means of which the second connecting adhesive tape is connected to the second end section of the backing tape. Preferably, the second connecting adhesive tape extends in a second connecting adhesive tape direction of extent. The second connecting adhesive tape preferably extends in the second connecting adhesive tape direction of extent away from the second end section of the backing tape. It has proven particularly advantageous that an extent of the connecting section of the second connecting adhesive tape in the second connecting adhesive tape direction of extent can correspond to between 20% and 40%, preferably between 30 and 35%, of an extent of the second connecting adhesive tape in the second connecting adhesive tape direction of extent since this ensures both a mechanically robust overlapping connection between the backing tape and the second connecting adhesive tape and a sufficiently large connecting adhesive surface of the second connecting adhesive tape for mechanically robust connections. This effect is observable over a total range of 20% to 40% and is particularly pronounced in a range of 30% to 35%. As a particular preference, the extent of the connecting section of the second connecting adhesive tape in the second connecting adhesive tape direction of extent corresponds to 33% of the extent of the second connecting adhesive tape in the second connecting adhesive tape direction of extent. It has surprisingly been found that at 33%, the overlapping connection between the backing tape and the second connecting adhesive tape and mechanically robust connections with the aid of the connecting adhesive surface of the second connecting adhesive tape can be matched to one another in a particularly advantageous manner.

In one embodiment, the material tape system has a roll core with a circumferential outer surface, wherein the second connecting adhesive tape is connected, in particular detachably, to the outer surface by means of the connecting adhesive surface. By virtue of the fact that the second connecting adhesive tape is connected, in particular detachably, to the outer surface by means of the connecting adhesive surface, the backing tape can be connected to the roll core by its second end section in such a way that, in the rolled-up state, the second end section of the backing tape is arranged radially inwardly in comparison with the first end section of the backing tape.

In one embodiment, a multiplicity of punched parts is arranged on the first side of the backing tape and/or a multiplicity of punched parts is arranged on the second side of the backing tape. The material tape system can therefore be used to provide punched parts. In particular, it has been found that the advantageous effects associated with this invention apply particularly to the case where a multiplicity of punched parts is arranged on the first side of the backing tape and/or a multiplicity of punched parts is arranged on the second side of the backing tape. In particular, it is possible for a multiplicity of punched parts to be arranged exclusively on the first side of the backing tape. Alternatively, it is possible for a multiplicity of punched parts to be arranged exclusively on the second side of the backing tape. It is furthermore possible both for a multiplicity of punched parts to be arranged on the first side of the backing tape and for a multiplicity of punched parts to be arranged on the second side of the backing tape. In this way, different arrangements of punched parts can be provided on the backing tape. By means of different arrangements of punched parts on the backing tape, it is possible to arrange the punched parts of the corresponding application in an optimum manner. It is thereby possible to provide material tape systems that can be used in a flexible manner.

According to a second aspect of the invention, the object stated at the outset is achieved by a material tape system assembly having the features of Patent claim14. The material tape system assembly has a first material tape system according to the first aspect of the invention. The material tape system assembly has a second material tape system according to the first aspect of the invention. The connecting adhesive surface of the first connecting adhesive tape of the first material tape system is connected to the second end section of the backing tape of the second material tape system on a second side of the backing tape of the second material tape system. It is thereby possible to provide a mechanically robust connection between the first material tape system and the second material tape system.

In a first embodiment, the connecting adhesive surface of the second connecting adhesive tape of the second material tape system is connected to the first end section of the backing tape of the first material tape system on the first side of the backing tape of the first material tape system. It is thereby possible to further increase the mechanical robustness of the connection between the first material tape system and the second material tape system.

In one embodiment, the backing tape of the first material tape system and the backing tape of the second material tape system are arranged in such a way that a first tangential surface running perpendicularly to the connecting adhesive surface of the first connecting adhesive tape of the first material tape system runs along a first edge region of the first end section of the backing tape of the first material tape system and along a first edge region of the second end section of the backing tape of the second material tape system, and a second tangential surface running parallel to the first tangential surface runs along a second edge region of the first end section of the backing tape of the first material tape system and along a second edge region of the second end section of the backing tape of the second material tape system. By virtue of this arrangement, the backing tape of the first material tape system and the backing tape of the second material tape system are aligned, which is advantageous particularly when the material tape system assembly is used in an automated robot applicator since, in particular, process stability and process reliability are thereby increased.

In one embodiment, a first end face of the first end section of the backing tape of the first material tape system and a second end face of the second end section of the backing tape of the second material tape system rest against one another. By virtue of the fact that the first end face of the first end section of the backing tape of the first material tape system and the second end face of the second end section of the backing tape of the second material tape system rest against one another, the backing tape of the first material tape system and the backing tape of the second material tape system can be positioned particularly precisely with respect to one another. Precise positioning of the backing tapes with respect to one another is advantageous particularly when the material tape system assembly is used in an automated robot applicator since the guidance of the material tape system assembly by the robot applicator is simplified and, in particular, the likelihood of the material tape system assembly being caught in the robot applicator is significantly reduced.

The features, technical effects and/or advantages described in connection with the material tape system according to the first aspect of the invention also apply at least in an analogous manner to the material tape system assembly according to the second aspect of the invention, and therefore corresponding repetition is dispensed with at this point.

According to a third aspect of the invention, the object stated at the outset is achieved by a method having the features of Patent claim18. The method is provided for producing a material tape system assembly according to the second aspect of the invention. The method has the following steps: providing the first material tape system; providing the second material tape system; detaching the fixing adhesive tape from the backing tape of the first material tape system; and connecting the connecting adhesive surface of the first connecting adhesive tape of the first material tape system to the second end section of the backing tape of the second material tape system on the second side of the backing tape of the second material tape system.

In one embodiment, the method has the following step: connecting the connecting adhesive surface of the second connecting adhesive tape of the second material tape system to the first end section of the backing tape of the first material tape system on the first side of the backing tape of the first material tape system.

Even if the method steps are described in a specific sequence, the present invention is not limited to this sequence. On the contrary, the individual method steps can be carried out in any appropriate sequence, in particular also, at least section-wise, in parallel with one another with respect to time.

The features, technical effects and/or advantages described in connection with the material tape system according to the first aspect of the invention and in connection with the material tape system assembly according to the second aspect of the invention also apply at least in an analogous manner to the method according to the third aspect of the invention, and therefore corresponding repetition is dispensed with at this point.

According to a fourth aspect of the invention, the object stated at the outset is achieved by a use having the features of Patent claim20. The use relates to a use of a material tape system according to the first aspect of the invention in an automated robot applicator. The features, technical effects and/or advantages described in connection with the material tape system according to the first aspect of the invention, in connection with the material tape system assembly according to the second aspect of the invention and in connection with the method according to the third aspect of the invention also apply at least in an analogous manner to the use according to the fourth aspect of the invention, and therefore corresponding repetition is dispensed with at this point.

FIG.1shows a schematic view of a first embodiment of a material tape system1according to the invention. The material tape system1has a backing tape3, a fixing adhesive tape5, a first connecting adhesive tape7, a second connecting adhesive tape9and a release tape11.

The backing tape3has a first end section13and a second end section15. The backing tape3extends from the first end section13to the second end section15. The backing tape3has a first side17and a second side19opposite to the first side17. The first end section13has a first end face21, which, in the first embodiment of the material tape system1according to the invention, is covered by the release tape11in the state shown inFIG.1. The second end section15has a second end face23, which, in the first embodiment of the material tape system1according to the invention, is exposed in the state shown inFIG.1. The first end face21is arranged opposite to the second end face23in a backing tape direction of extent in such a way that the first end face21and the second end face23point in opposite directions. The backing tape3has a release layer25, which, in the first embodiment of the material tape system1according to the invention, is a release paper, and a backing layer27connected to the release layer25. The release layer25has a surface, facing away from the backing layer27, with a section to which, in particular, pressure-sensitive adhesive surfaces can be connected and from which these pressure-sensitive adhesive surfaces can be detached particularly easily. The backing layer27ensures that the backing tape3is of mechanically robust design in its main plane of extent, in particular with respect to tensile loads in the main plane of extent. The release layer25is arranged on the first side17of the backing tape3. The backing layer27is arranged on the second side19of the backing tape3. By virtue of the fact that the release layer25is arranged on the first side17of the backing tape3and the backing layer27is arranged on the second side19of the backing tape3, the backing tape3can provide the functionality of the release layer27on the first side17and the functionality of the backing layer27on the second side19. The backing tape can be wound around a roll core (not illustrated inFIG.1) of the material tape system1.

The fixing adhesive tape5has a connecting section29and a fixing adhesive surface31. The fixing adhesive tape5is detachably connected to the first end section13of the backing tape3, more specifically to a section of the release layer25of the backing tape3, by means of the fixing adhesive surface31on the first side17of the backing tape3. The detachable connection between the fixing adhesive surface31of the fixing adhesive tape5and the first end section13of the backing tape3ensures that the fixing adhesive tape5is connected to the backing tape3and can be detached therefrom. In particular, the detachable connection between the fixing adhesive surface31of the fixing adhesive tape5and the section of the release layer25of the backing tape3ensures that the fixing adhesive tape5and the backing tape3can be detached from one another particularly easily, in particular when the connection between the fixing adhesive surface31of the fixing adhesive tape5and the section of the release layer25of the backing tape3is to be broken. The connection between the fixing adhesive tape5and the backing tape3ensures that the backing tape3can be connected with the aid of the fixing adhesive tape5to, for example, a roll core of the material tape system1or to a section of the backing tape3, in particular on the first side17of the backing tape3, particularly when the backing tape3is wound around the roll core. The detachment of the fixing adhesive tape5from the backing tape3ensures that the backing tape3can be decoupled from the roll core of the material tape system1or from the section of the backing tape3, in particular on the first side17of the backing tape3, in that the fixing adhesive tape5can be detached from the backing tape3during this process or subsequently. The detachable connection between the fixing adhesive tape5and the backing tape3ensures that the function of connecting the backing tape3, for example on the roll core of the material tape system1or on the section of the backing tape3, in particular on the first side17of the backing tape3, can be fulfilled by the fixing adhesive tape5and that the structural make up of the backing tape3can be chosen independently of this function.

The fixing adhesive tape5has a backing layer33and an adhesive layer35. The backing layer33ensures that the fixing adhesive tape5is of mechanically robust design in its main plane of extent, in particular with respect to tensile loads in the main plane of extent. The adhesive layer35is connected to the backing layer33. The adhesive layer35exhibits pressure-sensitive adhesion and thus ensures that the fixing adhesive tape5can be connected to other elements, such as, for example, the first end section13of the backing tape3or to the release tape11or both to the first end section13and to the release tape11. The adhesive layer35of the fixing adhesive tape5forms an adhesive surface which has a plurality of sections. A first section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5forms the fixing adhesive surface31, by means of which the fixing adhesive tape5is detachably connected to the first end section13of the backing tape3. A second section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5forms an adhesive surface by means of which the fixing adhesive tape5can be detachably connected, for example, to the roll core of the material tape system1or to a section of the backing tape3, in particular on the first side17of the backing tape3. The second section is exposed inFIG.1. Furthermore, a third section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5is provided. The third section is arranged between the first section and the second section and is covered by the release tape11inFIG.1.

The first connecting adhesive tape7has a connecting section37and a connecting adhesive surface39. By means of the connecting section37, the first connecting adhesive tape7is connected to the first end section13of the backing tape3on the second side19of the backing tape3, which is opposite to the first side17of the backing tape3. The connection between the connecting section37of the first connecting adhesive tape7and the first end section13of the backing tape3ensures that, when the first connecting adhesive tape7is connected to a further element, the backing tape3is connected to this further element via the first connecting adhesive tape7. In the first embodiment of the material tape system1according to the invention illustrated inFIG.1, the connecting adhesive surface39is covered by the release tape11.

The first connecting adhesive tape7has a backing layer41and an adhesive layer43. The backing layer41ensures that the first connecting adhesive tape7is of mechanically robust design in its main plane of extent, in particular with respect to tensile loads in the main plane of extent. The adhesive layer43is connected to the backing layer41. The adhesive layer43exhibits pressure-sensitive adhesion and thus ensures that the first connecting adhesive tape7can be connected to other elements, such as, for example, the first end section13of the backing tape3or to the release tape11or both to the first end section13and to the release tape11. The adhesive layer43of the first connecting adhesive tape7forms an adhesive surface which has a plurality of sections. A first section of the plurality of sections of the adhesive surface of the adhesive layer43of the first connecting adhesive tape7forms the connecting adhesive surface39of the first connecting adhesive tape7, said surface being covered by the release tape11inFIG.1. A second section of the plurality of sections of the adhesive surface of the adhesive layer43of the first connecting adhesive tape7, said second section being adjacent to the first section, forms an adhesive surface by means of which the first connecting adhesive tape7is connected to the first end section13of the backing tape3.

The first connecting adhesive tape7extends in a first connecting adhesive tape direction of extent45, the vector representation of which is arranged in the main plane of extent of the first connecting adhesive tape7. The first connecting adhesive tape7extends in the first connecting adhesive tape direction of extent45away from the first end section13of the backing tape3. It has proven particularly advantageous that an extent of the connecting section37of the first connecting adhesive tape7in the first connecting adhesive tape direction of extent45can correspond to between 20% and 40%, preferably between 30 and 35%, of an extent of the first connecting adhesive tape7in the first connecting adhesive tape direction of extent45since it is thereby possible to ensure both a mechanically robust overlapping connection between the backing tape3and the first connecting adhesive tape7and a sufficiently large connecting adhesive surface39of the first connecting adhesive tape7for mechanically robust connections. This effect is observable over a total range of 20% to 40% and is particularly pronounced in a range of 30% to 35%. In the first embodiment of the material tape system1according to the invention shown inFIG.1, the extent of the connecting section37of the first connecting adhesive tape7in the first connecting adhesive tape direction of extent45corresponds to 33% of the extent of the first connecting adhesive tape7in the first connecting adhesive tape direction of extent45. It has surprisingly been found that at 33%, the overlapping connection between the backing tape3and the first connecting adhesive tape7and mechanically robust connections with the aid of the connecting adhesive surface39of the first connecting adhesive tape7can be matched to one another in a particularly advantageous manner.

The second connecting adhesive tape9has a connecting section47and a connecting adhesive surface49. By means of the connecting section47, the second connecting adhesive tape9is connected to the second end section15of the backing tape3on the first side17of the backing tape3. The connection between the connecting section47of the second connecting adhesive tape9and the second end section15of the backing tape3ensures that, when the second connecting adhesive tape9is connected to a further element, the backing tape3is connected to this further element via the second connecting adhesive tape9. The connection between the connecting section47of the second connecting adhesive tape9and the second end section15of the backing tape3can ensure, for example, that the backing tape3can be connected with the aid of the second connecting adhesive tape9to, for example, a roll core of the material tape system1or to a section of the backing tape3, in particular on the first side17of the backing tape3, particularly when the backing tape3is wound around the roll core. In the first embodiment of the material tape system according to the invention illustrated inFIG.1, the connecting adhesive surface49is exposed.

The second connecting adhesive tape9has a backing layer51and an adhesive layer53. The backing layer51ensures that the second connecting adhesive tape9is of mechanically robust design in its main plane of extent, in particular with respect to tensile loads in the main plane of extent. The adhesive layer53is connected to the backing layer51. The adhesive layer53is pressure-sensitive and thus ensures that the second connecting adhesive tape9can be connected to other elements. The adhesive layer53of the second connecting adhesive tape9forms an adhesive surface which has a plurality of sections. A first section of the plurality of sections of the adhesive surface of the adhesive layer53of the second connecting adhesive tape9forms the connecting adhesive surface49of the second connecting adhesive tape9. A second section of the plurality of sections of the adhesive surface of the adhesive layer53of the second connecting adhesive tape9, said second section being adjacent to the first section, forms an adhesive surface by means of which the second connecting adhesive tape9is connected to the second end section15of the backing tape3.

The second connecting adhesive tape9extends in a second connecting adhesive tape direction of extent55, the vector representation of which is arranged in the main plane of extent of the second connecting adhesive tape9. The second connecting adhesive tape9extends in the second connecting adhesive tape direction of extent55away from the second end section15of the backing tape3. It has proven particularly advantageous that an extent of the connecting section47of the second connecting adhesive tape9in the second connecting adhesive tape direction of extent55can correspond to between 20% and 40%, preferably between 30 and 35%, of an extent of the second connecting adhesive tape9in the second connecting adhesive tape direction of extent55since this ensures both a mechanically robust overlapping connection between the backing tape3and the second connecting adhesive tape9and a sufficiently large connecting adhesive surface49of the second connecting adhesive tape9for mechanically robust connections. This effect is observable over a total range of 20% to 40% and is particularly pronounced in a range of 30% to 35%. In the first embodiment of the material tape system1according to the invention shown inFIG.1, the extent of the connecting section47of the second connecting adhesive tape9in the second connecting adhesive tape direction of extent55corresponds to 33% of the extent of the second connecting adhesive tape9in the second connecting adhesive tape direction of extent55. It has surprisingly been found that at 33%, the overlapping connection between the backing tape3and the second connecting adhesive tape9and mechanically robust connections with the aid of the connecting adhesive surface49of the second connecting adhesive tape9can be matched to one another in a particularly advantageous manner.

As already described, the backing tape3can be connected with the aid of the second connecting adhesive tape5to the roll core of the material tape system1or to a section of the backing tape3, in particular on the first side17of the backing tape3, particularly when the backing tape3is wound around the roll core3. In particular, when the backing tape3is wound around the roll core and the backing tape3is connected to the roll core of the material tape system1with the aid of the fixing adhesive tape5, the backing tape3can be connected to the section of the backing tape3, in particular on the first side17of the backing tape3, with the aid of the second connecting adhesive tape9. Alternatively, in particular when the backing tape3is wound around the roll core and the backing tape3is connected to the roll core of the material tape system1with the aid of the second connecting adhesive tape9, the backing tape3can be connected to the section of the backing tape3, in particular on the first side17of the backing tape3, with the aid of the fixing adhesive tape5. These two alternatives ensure that the backing tape3can be connected to the roll core and simultaneously to itself, in particular by means of a section on the first side17of the backing tape3, thus ensuring that the backing tape3remains in the state in which it is wound around the roll core. If the backing tape3is in the state in which it is wound around the roll core, the material tape system1can be stored in a particularly space-saving manner. In order to use the material tape system1, it is possible, when the backing tape3is connected to the section of the backing tape3, in particular on the first side17of the backing tape3, with the aid of the second connecting adhesive tape9, for the second connecting adhesive tape9to be detached from the section of the backing tape3and then for the backing tape3to be unwound from the roll core. If the backing tape3is connected to the section of the backing tape3, in particular on the first side17of the backing tape3, with the aid of the fixing adhesive tape5, the fixing adhesive tape5can be detached from the section of the backing tape3in order to use the material tape system1, and then the backing tape3can be unwound from the roll core. In connection with these two alternatives, the release layer25, in particular, has proven to be advantageous since this can have a section to which, in particular, the pressure-sensitive adhesive surfaces, such as, for example, the adhesive surface of the fixing adhesive tape5, by means of which the fixing adhesive tape5can be detachably connected to the section of the backing tape3on the first side17of the backing tape3, i.e. the second section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5, or the connecting adhesive surface49, can be connected and from which these pressure-sensitive adhesive surfaces can be detached particularly easily.

The release tape11has a release layer57, which, in the first embodiment of the material tape system1according to the invention, is a release paper, and a backing layer59connected to the release layer57. The release layer57preferably has a surface facing away from the backing layer59, to which surface it is possible, in particular, to connect pressure-sensitive adhesive surfaces, such as, for example, the connecting adhesive surface39of the first connecting adhesive tape7, and from which these pressure-sensitive adhesive surfaces can be detached particularly easily. The backing layer59ensures that the release tape11is of mechanically robust design in its main plane of extent, in particular with respect to tensile loads in the main plane of extent. Furthermore, the release tape11has a first side61and a second side63. The backing layer59is arranged on the first side61of the release tape11. The backing layer57is arranged on the second side63of the release tape11. The release tape11is arranged between the fixing adhesive tape5and the first connecting adhesive tape7. The release tape11rests against the first end face21of the first end section13and thereby covers the latter, thus ensuring that the first end face21is protected from mechanical effects, such as, for example, elastic or plastic deformations of the first end face21, such as, for example, cracks in the first end face21. As already described, in the configuration shown inFIG.1, the fixing adhesive tape5is connected to the backing tape3. In this case, the release tape11is arranged between the fixing adhesive tape5and the first connecting adhesive tape7in such a way that the first section, which forms the fixing adhesive surface31of the fixing adhesive tape5, the second section and the third section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5face the first side61of the release tape11. Here, the third section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5is covered by the release tape11. Furthermore, the release tape11is arranged between the fixing adhesive tape5and the first connecting adhesive tape7in such a way that the connecting adhesive surface39of the first connecting adhesive tape7faces the second side63of the release tape11. The connecting adhesive surface39of the first connecting adhesive tape7is preferably covered by the release tape11.

In the first embodiment of the material tape system1according to the invention shown inFIG.1, it is advantageous, in particular, that the fixing adhesive tape5and the first connecting adhesive tape7are each connected to the backing tape3in a certain way. To be specific, the fixing adhesive tape5and the first connecting adhesive tape7are connected to the backing tape3in such a way that, when the fixing adhesive tape5is connected to the backing tape3, the connecting adhesive surface39of the first connecting adhesive tape7is covered. The fixing adhesive tape5and the first connecting adhesive tape7are furthermore connected to the backing tape3in such a way that, when the fixing adhesive tape5is detached from the backing tape3, the connecting adhesive surface39of the first connecting adhesive tape7is exposed.

Thus, when the fixing adhesive tape5is connected to the backing tape3, the connecting adhesive surface39of the first connecting adhesive tape7is covered, ensuring that when the material tape system1is used, the first connecting adhesive tape7does not adhere with the connecting adhesive surface39to objects to which it is not intended to adhere. Furthermore, when the connecting adhesive surface39of the first connecting adhesive tape7is covered, the connecting adhesive surface39is protected from contamination when using the material tape system1.

Furthermore, when the fixing adhesive tape5is detached from the backing tape3, the connecting adhesive surface39of the first connecting adhesive tape7is exposed, thus making it possible, by detaching the fixing adhesive tape5from the backing tape3, to selectively expose the connecting adhesive surface39in order to connect it selectively to other elements, such as, for example, to the connecting adhesive surface49of the second connecting adhesive tape9of another material tape system1or to the second end section15of the backing tape3of the other material tape system1on the second side19of the backing tape3of the other material tape system1or both to the connecting adhesive surface49of the second connecting adhesive tape9of the other material tape system1and to the second end section15of the backing tape3of the other material tape system1on the second side19of the backing tape3of the other material tape system1.

In summary, the material tape system1ensures a plurality of functions by virtue of its construction and, in particular, by virtue of the fixing adhesive tape5and the interaction of the fixing adhesive tape5with the other elements of the material tape system1. First, the backing tape3can be detachably attached to further elements, such as, for example, to a roll core of the material tape system1, with the aid of the fixing adhesive tape5. Furthermore, the structural make up of the backing tape3can be selected independently of the function of detachable attachment of the backing tape3to further elements. This enables the backing tape3to be of particularly flexible design in terms of its intended use. For example, the backing tape3can be designed to be particularly light and at the same time mechanically robust, in particular tear-resistant. Moreover, the construction of the material tape system1and, in particular, the fixing adhesive tape5ensures the selective covering and exposure of the connecting adhesive surface39of the first connecting adhesive tape7, ensuring, on the one hand, that it is protected from contamination and, on the other hand, that it can be exposed when required. The material tape system1thus ensures that the backing tape3can be of mechanically robust design and that the use of the material tape system1is particularly user-friendly. The user-friendliness is ensured, in particular, by the fact that the connecting adhesive surface39can be exposed in a simple manner by detaching the fixing adhesive tape5from the backing tape3.

As already described, the first embodiment of the material tape system1according to the invention has the release tape11. The release tape11is designed, arranged and connected to the fixing adhesive tape5in such a way that, when the fixing adhesive tape5is connected to the backing tape3, the connecting adhesive surface39of the first connecting adhesive tape7is directly covered by the release tape11, i.e. the latter rests against the connecting adhesive surface39and completely covers it. Furthermore, the release tape11is designed, arranged and connected to the fixing adhesive tape5in such a way that, when the fixing adhesive tape5is detached from the backing tape3, the connecting adhesive surface39of the first connecting adhesive tape7is exposed, i.e. the release tape11does not rest against the connecting adhesive surface39and also does not cover the latter. The release tape11is connected on its first side61to the fixing adhesive tape5and is detachably connected on its second side63to the connecting adhesive surface39of the first connecting adhesive tape7in such a way that, when the fixing adhesive tape5is detached from the backing tape3, the release tape11is released from the connecting adhesive surface39. Thus, the connecting adhesive surface39can be exposed by removing the fixing adhesive tape5and thereby removing the release tape11.

The first embodiment of the material tape system1according to the invention is advantageous, in particular, by virtue of the arrangement of the backing tape3, of the fixing adhesive tape5, of the connecting adhesive tape7and of the release tape11relative to one another and by virtue of their interactions with one another, in particular by virtue of the interaction of different pressure-sensitive adhesive surfaces whose pressure-sensitive adhesive properties are matched to one another.

The fixing adhesive tape5has the pressure-sensitive adhesive layer35, which has the adhesive surface with the plurality of sections. The first section of the plurality of sections of the adhesive surface of the adhesive layer35forms the pressure-sensitive fixing adhesive surface5, by means of which the fixing adhesive tape5is detachably connected to the first end section13of the backing tape3on the first side17of the backing tape3. In this case, the pressure-sensitive fixing adhesive surface31is connected to a section of the release layer25of the backing tape3, wherein the surface of this section of the release layer25does not have pressure-sensitive adhesive properties, and therefore the pressure-sensitive fixing adhesive surface31can be detached particularly easily from this surface of the section of the release layer25.

Between the first section and the second section (which is exposed inFIG.1) of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5, the third section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5is provided. The third section forms a pressure-sensitive adhesive surface, by means of which the fixing adhesive tape5is connected to a surface of the backing layer59of the release tape11on the first side61of the release tape11. The surface of the backing layer59of the release tape11itself is not of pressure-sensitive adhesive design. However, in comparison with the surface of the section of the release layer25, the surface of the backing layer59of the release tape11is designed in such a way that the material bond between the fixing adhesive tape5and the release tape11is mechanically more robust than the material bond between the fixing adhesive tape5and the backing tape3.

The first connecting adhesive tape7has the pressure-sensitive adhesive layer43, which has the adhesive surface with the plurality of sections. The first section of the plurality of sections of the adhesive surface of the adhesive layer43forms the pressure-sensitive connecting adhesive surface39, which is covered by the release tape11inFIG.1. In this case, the pressure-sensitive connecting adhesive surface39is connected on the second side63of the release tape11to a surface of the release layer57of the release tape11. The surface of the release layer57of the release tape11itself is not of pressure-sensitive adhesive design. However, in comparison with the surface of the backing layer59of the release tape11, the surface of the backing layer57of the release tape11is designed in such a way that the material bond between the fixing adhesive tape5and the release tape11is mechanically more robust than the material bond between the release tape5and the first connecting adhesive tape7.

In the first embodiment of the material tape system1according to the invention, the pressure-sensitive adhesive properties of the different pressure-sensitive adhesive surfaces are matched to one another as follows. A first adhesive force acting from the fixing adhesive surface31to the backing tape3is less than a second adhesive force acting from the connecting section29of the fixing adhesive tape5to the release tape11. In this case, the second adhesive force acts from the third section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5to the release tape11. Furthermore, the second adhesive force acting from the connecting section29of the fixing adhesive tape5to the release tape11is greater than a third adhesive force acting from the connecting adhesive surface39of the first connecting adhesive tape7to the release tape11. Furthermore, the third adhesive force acting from the connecting adhesive surface39of the first connecting adhesive tape7to the release tape11is less than a fourth adhesive force acting from the connecting section37of the first connecting adhesive tape7to the first end section13of the backing tape3.

The first, second, third and fourth adhesive forces are each to be understood to mean a force threshold which must be overcome in order to detach the corresponding elements from one another under a load in the plane of the image inFIG.1and perpendicular to the first connecting adhesive tape direction of extent45. The first adhesive force is a force threshold which must be overcome in order to detach the backing tape3and the fixing adhesive tape5from one another, the second adhesive force is a force threshold which must be overcome in order to detach the fixing adhesive tape5and the release tape11from one another, the third adhesive force is a force threshold which must be overcome in order to detach the first connecting adhesive tape7and the release tape11from one another, and the fourth adhesive force is a force threshold which must be overcome in order to detach the first connecting adhesive tape7and the backing tape3from one another.

When the material tape system1is then subjected to a tensile load in the plane of the image inFIG.1and perpendicular to the first connecting adhesive tape direction of extent45, in that a tensile force acts on the fixing adhesive tape5and an oppositely acting tensile force acts on the first connecting adhesive tape7, both the backing tape3and the fixing adhesive tape5are detached from one another and the connecting adhesive tape7and the release tape11are detached from one another, wherein both the fixing adhesive tape5and the release tape11and also the backing tape3and the first connecting adhesive tape7remain connected to one another.

Owing to the geometrical construction of the first embodiment of the material tape system1according to the invention, the ratios of the adhesive forces to one another ensure the desired result of the described detachment of the individual elements. The first embodiment of the material tape system1according to the invention is furthermore built up in such a way that the pressure-sensitive adhesive properties of the different pressure-sensitive adhesive surfaces are matched to one another as follows. A first strength threshold value of the connection between the fixing adhesive surface31and the backing tape3is lower than a second strength threshold value of the connection between the connecting section29of the fixing adhesive tape5and the release tape11. In this case, the second strength threshold relates to the connection between the third section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5and the release tape11. Furthermore, the second strength threshold value of the connection between the connecting section29of the fixing adhesive tape5and the release tape11is higher than a third strength threshold value of the connection between the connecting adhesive surface39of the first connecting adhesive tape7and the release tape11. Furthermore, the third strength threshold value of the connection between the connecting adhesive surface39of the first connecting adhesive tape7and the release tape11is lower than a fourth strength threshold value of the connection between the connecting section37of the first connecting adhesive tape7and the first end section13of the backing tape3. The first, second, third and fourth strength threshold values are each to be understood to mean a strength threshold value which must be overcome in order to detach the corresponding elements from one another under a load in the plane of the image inFIG.1and perpendicular to the first connecting adhesive tape direction of extent45. The first strength threshold value is a strength threshold value which must be overcome in order to detach the backing tape3and the fixing adhesive tape5from one another, the second strength threshold value is a strength threshold value which must be overcome in order to detach the fixing adhesive tape5and the release tape11from one another, the third strength threshold value is a strength threshold value which must be overcome in order to detach the first connecting adhesive tape7and the release tape11from one another, and the fourth strength threshold value is a strength threshold value which must be overcome in order to detach the first connecting adhesive tape7and the backing tape3from one another.

The features, technical effects and/or advantages described in connection with the first, second, third and fourth adhesive forces and in connection with the first, second, third and fourth strength threshold values also apply, at least in an analogous manner, to a first, second, third and fourth peeling force, which describes the force threshold which must be overcome in order to pull one element off another element. If, for example, in the first embodiment of the material tape system1according to the invention, the end of the fixing adhesive tape5which is on the outside left inFIG.1is initially pulled upwards perpendicularly to the first connecting adhesive tape direction of extent45and then upwards and counter to the first connecting adhesive tape direction of extent45in the plane of the image inFIG.1, both the backing tape3and the fixing adhesive tape5as well as the connecting adhesive tape7and the release tape11are detached from one another owing to the ratios of the first, second, third and fourth peeling forces with respect to one another, wherein both the fixing adhesive tape5and the release tape11as well as the backing tape3and the first connecting adhesive tape7remain connected to one another.

As already described, the material tape system1can have a roll core with a circumferential outer surface. The fixing adhesive tape5can be connected to the outer surface by means of the connecting section29, in particular by means of the second section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5. Alternatively, the second connecting adhesive tape9can be detachably connected to the circumferential outer surface of the roll core by means of the connecting adhesive surface49.

FIG.2shows a schematic view of a second embodiment of the material tape system1according to the invention. The material tape system1has the backing tape3, the fixing adhesive tape5, the first connecting adhesive tape7and the second connecting adhesive tape9. In comparison with the first embodiment of the material tape system1according to the invention inFIG.1, the material tape system1according to the second embodiment does not have a release tape11. In particular, the arrangement of the backing tape3, the fixing adhesive tape5and the first connecting adhesive tape7which is provided in the second embodiment of the material tape system1according to the invention ensures that it is possible to dispense with a release tape11of the kind provided in the first embodiment of the material tape system1according to the invention. Thus, the second embodiment of the material tape system1according to the invention represents a particularly resource-saving alternative. As in the first embodiment of the material tape system1according to the invention, the release layer25of the backing tape3in the second embodiment of the material tape system1according to the invention is a release paper.

In the second embodiment of the material tape system1according to the invention too, the fixing adhesive tape5and the first connecting adhesive tape7are connected to the backing tape3in such a way that, when the fixing adhesive tape5is connected to the backing tape3, the connecting adhesive surface39of the first connecting adhesive tape7is covered, and, when the fixing adhesive tape5is detached from the backing tape3, the connecting adhesive surface39of the first connecting adhesive tape7is exposed. As shown inFIG.2, when the fixing adhesive tape5is connected to the backing tape3, the connecting adhesive surface39of the first connecting adhesive tape7is arranged on the first side17of the backing tape3. The arrangement of the connecting adhesive surface39of the first connecting adhesive tape7on the first side17of the backing tape3can be achieved as shown inFIG.2by the first connecting adhesive tape7being wrapped around the first end section13of the backing tape. The first connecting adhesive tape7is arranged in a U shape and encloses the first end section13of the backing tape3in such a way that the first end face21is covered by the first connecting adhesive tape7.

The fixing adhesive tape5has the pressure-sensitive adhesive layer35, which has the adhesive surface with the plurality of sections. The first section of the plurality of sections of the adhesive surface of the adhesive layer35forms the pressure-sensitive fixing adhesive surface5, by means of which the fixing adhesive tape5is detachably connected to the first end section13of the backing tape3on the first side17of the backing tape3. In this case, the pressure-sensitive fixing adhesive surface31is connected to a section of the release layer25of the backing tape3, wherein the surface of this section of the release layer25does not have pressure-sensitive adhesive properties, and therefore the pressure-sensitive fixing adhesive surface31can be detached particularly easily from this surface of the section of the release layer25.

Between the first section and the second section (which is exposed inFIG.2) of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5, the third section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5is provided. The third section forms a pressure-sensitive adhesive surface, by means of which the fixing adhesive tape5is connected to a surface of a section of the backing layer41of the first connecting adhesive tape7on the side of the backing layer41of the first connecting adhesive tape7. The surface of the section of the backing layer41of the first connecting adhesive tape7is itself not of pressure-sensitive adhesive design. However, in comparison with the surface of the section of the release layer25, the surface of the section of the backing layer41of the first connecting adhesive tape7is designed in such a way that the material bond between the fixing adhesive tape5and the first connecting adhesive tape7is mechanically more robust than the material bond between the fixing adhesive tape5and the backing tape3.

The first connecting adhesive tape7has the pressure-sensitive adhesive layer43, which has the adhesive surface with the plurality of sections. The first section of the plurality of sections of the adhesive surface of the adhesive layer43forms the pressure-sensitive connecting adhesive surface39, which is covered by a surface of a section of the release layer25of the release tape3inFIG.2. In this case, the pressure-sensitive connecting adhesive surface39on the first side17of the backing tape3is connected to the surface of the section of the release layer25of the backing tape3which is arranged on the first end section13of the backing tape3. The surface of the section of the release layer25is not of pressure-sensitive adhesive design. In comparison with that surface of the section of the backing layer7of the first connecting adhesive tape7which faces the fixing tape5, the surface of the section of the backing layer25on the first end section13is designed in such a way that the material bond between the fixing adhesive tape5and the first connecting adhesive tape7is mechanically more robust than the material bond between the first connecting adhesive tape7and the backing tape3on the first side17of the backing tape3. The second section of the plurality of sections of the adhesive surface of the adhesive layer43of the first connecting adhesive tape7is arranged on the second side19of the backing tape3and forms a pressure-sensitive adhesive surface by means of which the first connecting adhesive tape7is connected to a surface of a section of the backing layer27of the backing tape3at the first end section13of the backing tape3.

In comparison with the surface of the section of the release layer25of the backing tape3on the first end section13of the backing tape3on the first side17of the backing tape3, the surface of the section of the backing layer27of the backing tape3on the first end section13of the backing tape3on the second side19of the backing tape3is designed in such a way that the material bond between the backing tape3and the first connecting adhesive tape7on the second side19of the backing tape3is mechanically more robust than the material bond between the backing tape3and the first connecting adhesive tape7on the first side17of the backing tape3.

In the second embodiment of the material tape system1according to the invention, the pressure-sensitive adhesive properties of the different pressure-sensitive adhesive surfaces are matched to one another as follows. A first adhesive force acting from the fixing adhesive surface31to the backing tape3is less than a second adhesive force acting from the connecting section29of the fixing adhesive tape5to the first connecting adhesive tape7. In this case, the second adhesive force acts from the third section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5to the first connecting adhesive tape7. Furthermore, the second adhesive force acting from the connecting section29of the fixing adhesive tape5to the first connecting adhesive tape7is greater than a third adhesive force acting from the connecting adhesive surface39of the first connecting adhesive tape7to the first end section13of the backing tape13. Furthermore, the third adhesive force acting from the connecting adhesive surface39of the first connecting adhesive tape7to the first end section13of the backing tape13is less than a fourth adhesive force acting from the connecting section37of the first connecting adhesive tape7to the first end section13of the backing tape3.

The first, second, third and fourth adhesive forces are each to be understood to mean a force threshold which must be overcome in order to detach the corresponding elements from one another under a load in the plane of the image inFIG.2and perpendicular to the first connecting adhesive tape direction of extent45. The first adhesive force is a force threshold which must be overcome in order to detach the backing tape3and the fixing adhesive tape5from one another, the second adhesive force is a force threshold which must be overcome in order to detach the fixing adhesive tape5and the first connecting adhesive tape7from one another, the third adhesive force is a force threshold which must be overcome in order to detach the first connecting adhesive tape7and the backing tape3from one another on the first side17of the backing tape3, and the fourth adhesive force is a force threshold which must be overcome in order to detach the first connecting adhesive tape7and the backing tape3from one another on the second side19of the backing tape3.

When the material tape system1is then subjected to a tensile load in the plane of the image inFIG.1and perpendicular to the first connecting adhesive tape direction of extent45, in that a tensile force acts on the fixing adhesive tape5and an oppositely acting tensile force acts on the first connecting adhesive tape7on the second side19of the backing tape3, both the backing tape3and the fixing adhesive tape5are detached from one another and the first connecting adhesive tape7and the backing tape3are detached from one another on the first side17of the backing tape3, wherein first of all both the fixing adhesive tape5and the first connecting adhesive tape7and also the backing tape3and the first connecting adhesive tape7remain connected to one another on the second side19of the backing tape3. Subsequently, the fixing adhesive tape5can be detached from the first connecting adhesive tape7and the section of the first connecting adhesive tape7which is arranged on the first side17of the backing tape3inFIG.2can be folded over in the direction of the first connecting adhesive tape direction of extent45, with the result that the first connecting adhesive tape7extends along the first connecting adhesive tape direction of extent45. By removing the fixing adhesive tape5and folding over the first connecting adhesive tape7, the connecting adhesive surface39of the first connecting adhesive tape7can be exposed.

Owing to the geometrical construction of the second embodiment of the material tape system1according to the invention, the ratios of the adhesive forces to one another ensure the desired result of the described detachment of the individual elements. The second embodiment of the material tape system1according to the invention is furthermore built up in such a way that the pressure-sensitive adhesive properties of the different pressure-sensitive adhesive surfaces are matched to one another as follows. A first strength threshold value of the connection between the fixing adhesive surface31and the backing tape3is lower than a second strength threshold value of the connection between the connecting section29of the fixing adhesive tape5and the first connecting adhesive tape7. In this case, the second strength threshold relates to the connection between the third section of the plurality of sections of the adhesive surface of the adhesive layer35of the fixing adhesive tape5and the first connecting adhesive tape7. Furthermore, the second strength threshold value of the connection between the connecting section29of the fixing adhesive tape5and the first connecting adhesive tape11is higher than a third strength threshold value of the connection between the connecting adhesive surface39of the first connecting adhesive tape7and the first end section13of the backing tape13. Furthermore, the third strength threshold value of the connection between the connecting adhesive surface39of the first connecting adhesive tape7and the first end section13of the backing tape11is lower than a fourth strength threshold value of the connection between the connecting section37of the first connecting adhesive tape7and the first end section13of the backing tape3. The first, second, third and fourth strength threshold values are each to be understood to mean a strength threshold value which must be overcome in order to detach the corresponding elements from one another under a load in the plane of the image inFIG.2and perpendicular to the first connecting adhesive tape direction of extent45. The first strength threshold value is a strength threshold value which must be overcome in order to detach the backing tape3and the fixing adhesive tape5from one another, the second strength threshold value is a strength threshold value which must be overcome in order to detach the fixing adhesive tape5and the first connecting adhesive tape7from one another, the third strength threshold value is a strength threshold value which must be overcome in order to detach the first connecting adhesive tape7and the backing tape3from one another on the first side17of the backing tape3, and the fourth strength threshold value is a strength threshold value which must be overcome in order to detach the first connecting adhesive tape7and the backing tape3from one another on the second side19of the backing tape3.

The features, technical effects and/or advantages described in connection with the first, second, third and fourth adhesive forces and in connection with the first, second, third and fourth strength threshold values also apply, at least in an analogous manner, to a first, second, third and fourth peeling force, which describes the force threshold which must be overcome in order to pull one element off another element. If, for example, in the second embodiment of the material tape system1according to the invention, the end of the fixing adhesive tape5which is on the outside right inFIG.2is initially pulled upwards perpendicularly to the first connecting adhesive tape direction of extent45and then upwards and counter to the first connecting adhesive tape direction of extent45in the plane of the image inFIG.2, the fixing adhesive tape5and the first connecting adhesive tape7are first detached from one another and, together with this, in particular simultaneously therewith, the first connecting adhesive tape7and the backing tape3are detached from one another on the first side17of the backing tape3and then the fixing adhesive tape5and the backing tape3are detached from one another owing to the ratios of the first, second, third and fourth peeling forces with respect to one another, wherein the first connecting adhesive tape7and the backing tape3remain connected to one another on the second side19of the backing tape3.

The features, technical effects and/or advantages described in connection with the first embodiment of the material tape system1according to the invention also apply at least in an analogous manner to the second embodiment of the material tape system according to the invention.

FIG.3shows a schematic view of one embodiment of a material tape system assembly65according to the invention.FIG.4shows two schematic views of the embodiment of the material tape system assembly65according to the invention inFIG.3in a top view (FIG.4a) and in a view from below (FIG.4b). The material tape system assembly65has a first material tape system1according to a third embodiment of the material tape system1according to the invention and a second material tape system1according to the third embodiment of the material tape system1according to the invention. The connecting adhesive surface39of the first connecting adhesive tape7of the first material tape system1is connected to the second end section15of the backing tape3of the second material tape system1on a second side19of the backing tape3of the second material tape system1. The connecting adhesive surface49of the second connecting adhesive tape9of the second material tape system1is connected to the first end section13of the backing tape3of the first material tape system1on the first side17of the backing tape3of the first material tape system1.

As already described, the material tape system assembly65shown inFIG.3has the first material tape system1and the second material tape system1in each case according to the third embodiment of the material tape system1according to the invention. When the third embodiment of the material tape system1according to the invention is used, the first end section13of the backing tape3of the first material tape system1is arranged between the second end section15of the backing tape3of the second material tape system1and the connecting adhesive surface49of the second connecting adhesive tape9, and the second end section15of the backing tape3of the second material tape system1is arranged between the first end section13of the backing tape3of the first material tape system1and the connecting adhesive surface39of the first connecting adhesive tape7. By this means, a particularly space-saving material tape system assembly65is provided. When the first or second embodiment of the material tape system1according to the invention is used, the first end face21of the first end section13of the backing tape3of the first material tape system1and the second end face23of the second end section15of the backing tape3of the second material tape system1can rest against one another. As a result, the backing tape3of the first material tape system1and the backing tape3of the second material tape system1are aligned, which is advantageous, in particular, when the material tape system assembly65is used in an automated robot applicator since the guidance of the material tape system assembly65by the robot applicator is simplified and, in particular, the likelihood of the material tape system assembly65being caught in the robot applicator is significantly reduced.

The first end section13of the backing tape11has a first edge region67and a second edge region69. The second end section15of the backing tape11has a first edge region71and a second edge region73. The backing tape3of the first material tape system1and the backing tape3of the second material tape system1are arranged in such a way that a first tangential surface running perpendicularly to the connecting adhesive surface39of the first connecting adhesive tape7of the first material tape system1runs along the first edge region67of the first end section13of the backing tape3of the first material tape system1and along a first edge region71of the second end section15of the backing tape3of the second material tape system1, and a second tangential surface running parallel to the first tangential surface runs along the second edge region69of the first end section13of the backing tape3of the first material tape system1and along the second edge region73of the second end section15of the backing tape3of the second material tape system1. By virtue of this arrangement, the backing tape3of the first material tape system1and the backing tape3of the second material tape system1are aligned, which is advantageous particularly when the material tape system assembly65is used in an automated robot applicator.

In the embodiment of the material tape system assembly65according to the invention which is illustrated inFIGS.3and4, a multiplicity of punched parts75is arranged on the first side17of each backing tape3. In other embodiments (not shown) of the material tape system assembly65according to the invention, it is possible for a multiplicity of punched parts75to be arranged exclusively on the second side19of the backing tape3. In other embodiments (not shown) of the material tape system assembly65according to the invention, it is possible both for a multiplicity of punched parts75to be arranged on the first side17of the backing tape3and for a multiplicity of punched parts75to be arranged on the second side19of the backing tape3. Thus, different arrangements of punched parts75can be provided on the backing tape3. By means of different arrangements of punched parts75on the backing tape3, it is possible to arrange the punched parts75of the corresponding application in an optimum manner. It is thereby possible to provide material tape systems1and material tape system assemblies65that can be used in a flexible manner.

As already described, the detachable connection between the fixing adhesive tape5and the backing tape3ensures that the function of connecting the backing tape3, for example to the roll core of the material tape system1or to the section of the backing tape3, in particular on the first side17of the backing tape3, can be fulfilled by the fixing adhesive tape5and that the structural make up of the backing tape3can be chosen independently of this function. This has been found to be advantageous particularly in the case in which a multiplicity of punched parts75is arranged on the first side17of the backing tape3and/or a multiplicity of punched parts75is arranged on the second side19of the backing tape3since in this case the backing tape3can be constructed in a manner that is structurally adapted to the multiplicity of punched parts75.

In particular, the release layer25has been found to be advantageous since it can have a section to which, in particular, the pressure-sensitive adhesive surfaces, such as, for example, the adhesive surface of the fixing adhesive tape5, by means of which the fixing adhesive tape5can be detachably connected to the section of the backing tape3on the first side17of the backing tape3, or the connecting adhesive surface49, can be connected and from which these pressure-sensitive adhesive surfaces can be detached particularly easily, in particular when the material tape system1is to be used, for example, in an automated robot applicator for applying a multiplicity of punched parts75.

The material tape system assembly65is produced as follows. The first material tape system1and the second material tape system1are provided. The fixing adhesive tape5is then detached from the backing tape3of the first material tape system1. After this, the connecting adhesive surface39of the first connecting adhesive tape7of the first material tape system1is connected to the second end section15of the backing tape3of the second material tape system1on the second side19of the backing tape3of the second material tape system1. The connecting adhesive surface49of the second connecting adhesive tape9of the second material tape system1is then connected to the first end section13of the backing tape3of the first material tape system1on the first side17of the backing tape3of the first material tape system1.

The features, technical effects and/or advantages described in connection with the first embodiment of the material tape system1according to the invention and the features, technical effects and/or advantages described in connection with the second embodiment of the material tape system1according to the invention also apply at least in an analogous manner to the third embodiment of the material tape system1according to the invention and to the embodiment of the material tape system assembly65according to the invention.

In addition, it should be noted that “having” does not exclude other elements or steps and “one” or “a” does not exclude a multiplicity. Attention is furthermore drawn to the fact that features which have been described with reference to one of the above exemplary embodiments can also be used in combination with other features of other exemplary embodiments described above. Reference signs in the claims should not be regarded as a restriction.
