[0007] From JP 2002 - 80 150 A a method for splicing a label tape and a device for splicing the label tape are known.

[0008] In general, it is desirable to provide material belt systems that simplify handling, ensure time-efficient and resource-saving processes, and increase process stability and reliability.

[0009] It is therefore an object of the present invention to simplify handling, to ensure time-efficient and resource-saving processes and to increase process stability and process reliability.

[0010] According to a first aspect of the invention, the stated object is achieved by a material tape system having the features of patent claim 1. The material tape system has a carrier tape. The carrier tape has a first end section and a second end section. The carrier tape extends from the first end section to the second end section. The material tape system has an adhesive fixing tape. The adhesive fixing tape has an adhesive fixing surface. The adhesive fixing tape is detachably connected to the first end section of the carrier tape on a first side of the carrier tape by means of the adhesive fixing surface. The material tape system has a first connecting adhesive tape. The first connecting adhesive tape has a connecting section. The first connecting adhesive tape is connected to the first end section of the carrier tape on a second side of the carrier tape opposite the first side of the carrier tape by means of the connecting section.The fixing adhesive tape and the first bonding adhesive tape are bonded to the carrier tape in such a way that when the fixing adhesive tape is bonded to the carrier tape, a bonding adhesive surface of the first bonding adhesive tape is covered, and when the fixing adhesive tape is detached from the carrier tape, the bonding adhesive surface of the first bonding adhesive tape is exposed.

[0011] The material tape system comprises the carrier tape. The carrier tape has the first end section and the second end section and extends from the first end section to the second end section. Preferably, the first end section has a first end face. Preferably, the second end section has a second end face. In particular, the carrier tape extends from the first end section to the second end section in a carrier tape extension direction. Preferably, the first end face is arranged opposite the second end face in the carrier tape extension direction such that the first end face and the second end face point in opposite directions. The carrier tape can have a release layer, which can be a release paper. Furthermore, the carrier tape can have a carrier layer connected to the release layer.The release layer preferably has a surface facing away from the carrier 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 particularly easily detached. For example, a plurality of, in particular self-adhesive, punched parts can be arranged on this section of the surface of the release layer. The carrier layer ensures that the carrier tape is mechanically robust in its main extension plane, in particular with respect to tensile loads in the main extension plane. The release layer can be arranged on the first side of the carrier tape. Alternatively, the release layer can also be arranged on the second side of the carrier tape. In a further alternative, the carrier tape only has the release layer and in particular no carrier layer. The carrier layer can be arranged on the second side of the carrier tape.Alternatively, the carrier layer can also be arranged on the first side of the carrier tape. In the event that both the release layer and the carrier layer are provided, if the release layer is arranged on the first side of the carrier tape and the carrier layer is arranged on the second side of the carrier tape, the carrier tape can provide the functionality of the release layer on the first side and the functionality of the carrier layer on the second side. If the release layer is arranged on the second side of the carrier tape and the carrier layer is arranged on the first side of the carrier tape, the carrier tape can provide the functionality of the release layer on the second side and the functionality of the carrier layer on the first side. The carrier tape can be wound around a roll core of the material tape system.

[0012] The material tape system comprises the fixing adhesive tape. The fixing adhesive tape preferably comprises a carrier layer and an adhesive layer. The carrier layer ensures that the fixing adhesive tape is mechanically robust in its main extension plane, particularly with respect to tensile loads in the main extension plane. The adhesive layer is preferably bonded to the carrier layer. The adhesive layer is preferably pressure-sensitively adhesive. The pressure-sensitive adhesiveness of the adhesive layer ensures that the fixing adhesive tape can be bonded to other elements, such as to the first end section of the carrier tape or to a release tape, or to both the first end section and the release tape. The fixing adhesive tape comprises the fixing adhesive surface. The fixing adhesive surface releasably bonds the fixing adhesive tape on the first side of the carrier tape to the first end section of the carrier tape.The detachable connection between the fixing adhesive surface of the fixing adhesive tape and the first end section of the carrier tape ensures that the fixing adhesive tape is connected to the carrier tape and can be detached therefrom. Preferably, the fixing adhesive tape is detachably connected to the fixing adhesive surface on the first side of the carrier tape with a section of the separating layer of the carrier tape at the first end section of the carrier tape. In particular, the detachable connection between the fixing adhesive surface of the fixing adhesive tape and the section of the separating layer of the carrier tape ensures that the fixing adhesive tape and the carrier tape can be particularly easily detached from one another, especially when the connection between the fixing adhesive surface of the fixing adhesive tape and the section of the separating layer of the carrier tape is to be removed.

[0013] The connection between the fixing adhesive tape and the carrier tape ensures that the carrier tape can be connected, for example, to the roll core of the material tape system or to a section of the carrier tape, in particular on the first side of the carrier tape, using the fixing adhesive tape, especially when the carrier tape is wound around the roll core. The carrier tape can therefore be connected to itself in the wound state using the fixing adhesive tape, so that the carrier tape remains in the wound state. Detaching the fixing adhesive tape from the carrier tape ensures that the carrier tape can be decoupled from the roll core of the material tape system or from the section of the carrier tape, in particular on the first side of the carrier tape, and that the fixing adhesive tape can be detached from the carrier tape during or after this process.The detachable connection between the fixing adhesive tape and the carrier tape ensures that the function of connecting the carrier tape, for example to the roll core of the material tape system or to the section of the carrier tape, in particular on the first side of the carrier tape, can be fulfilled by the fixing adhesive tape and the structural design of the carrier tape can be selected independently of this function.

[0014] The adhesive layer of the fixing adhesive tape can form an adhesive surface having 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 with which the fixing adhesive tape is releasably connected to the first end section of the carrier 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 with which the fixing adhesive tape can be releasably connected, for example, to the roll core of the material tape system or to a section of the carrier tape, in particular on the first side of the carrier tape. The second section can be exposed, in particular if the fixing adhesive tape is not releasably connected to the roll core of the material tape system or to a section of the carrier tape, in particular on the first side of the carrier 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.

[0015] The material tape system comprises the first bonding adhesive tape. The first bonding adhesive tape preferably comprises a carrier layer and an adhesive layer. The carrier layer ensures that the first bonding adhesive tape is mechanically robust in its main extension plane, in particular with respect to tensile loads in the main extension plane. The adhesive layer can be bonded to the carrier layer. The adhesive layer is preferably pressure-sensitively adhesive. The pressure-sensitive adhesiveness of the adhesive layer ensures that the first bonding adhesive tape can be bonded to other elements, such as the first end section of the carrier tape or to the release tape, or to both the first end section and the release tape.

[0016] The adhesive layer of the first connecting adhesive tape preferably forms an adhesive surface having 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, adjacent to the first section, preferably forms an adhesive surface with which the first connecting adhesive tape is connected to the first end section of the carrier tape.

[0017] The first connecting adhesive tape has the connecting portion. The first connecting adhesive tape is connected to the first end portion of the carrier tape on the second side of the carrier tape opposite the first side of the carrier tape by means of the connecting portion. The connection between the connecting portion of the first connecting adhesive tape and the first end portion of the carrier tape ensures that, when the first connecting adhesive tape is connected to another element, the carrier tape is connected to this other 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 carrier 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, with which the first connecting adhesive tape is connected to the first end section of the carrier tape.

[0018] The fixing adhesive tape and the first connecting adhesive tape are bonded to the carrier tape in such a way that, when the fixing adhesive tape is bonded to the carrier tape, the bonding adhesive surface of the first connecting adhesive tape is covered. In this case, the bonding adhesive surface can be covered by the release tape. When the fixing adhesive tape is bonded to the carrier tape, the bonding adhesive surface of the first connecting adhesive tape is covered, so that when the material tape system is used, the first connecting adhesive tape does not stick to objects to which it is not intended to stick. Furthermore, when the bonding adhesive surface of the first connecting adhesive tape is covered, the bonding adhesive surface is protected from contamination when the material tape system is used.

[0019] The fixing adhesive tape and the first bonding adhesive tape are bonded to the carrier tape in such a way that when the fixing adhesive tape is detached from the carrier tape, the bonding adhesive surface of the first bonding adhesive tape is exposed.Because the connecting adhesive surface of the first connecting adhesive tape is exposed when the fixing adhesive tape is detached from the carrier tape, the connecting adhesive surface can be specifically exposed by detaching the fixing adhesive tape from the carrier tape in order to specifically connect it 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 carrier tape of the other material tape system on the second side of the carrier 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 carrier tape of the other material tape system on the second side of the carrier tape of the other material tape system.

[0020] In particular, the material tape system ensures multiple functions through its structure, particularly through the adhesive fixing tape and the interaction of the adhesive fixing tape with the other elements of the material tape system. Firstly, the carrier tape can be removably attached to other elements using the adhesive fixing tape, such as a roller of the material tape system. Furthermore, the structural design of the carrier tape can be selected independently of the function of removably attaching the carrier tape to other elements. This allows the carrier tape to be designed with particular flexibility, tailored to its intended use. For example, the carrier tape can be designed to be particularly lightweight and at the same time mechanically robust, particularly tear-resistant.Furthermore, the design of the material tape system, and in particular the fixing adhesive tape, ensures the targeted covering and exposure of the connecting adhesive surface of the first connecting adhesive tape, so that it is protected from contamination on the one hand, and can be exposed as needed on the other. The material tape system thus ensures that the carrier tape can be mechanically robust and that the use of the material tape system is particularly user-friendly. User-friendliness is particularly ensured by the fact that the connecting adhesive surface can be easily exposed by detaching the fixing adhesive tape from the carrier tape.

[0021] As already indicated, the material tape system, which can also be referred to as the first material tape system, can be connected to another 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 connection can also be referred to as a material tape system connection. In particular, it is provided that in the first material tape system, the fixing adhesive tape is first detached from the carrier tape, so 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. In the material tape system connection, at least the first material tape system therefore has the fixing adhesive tape detached from the carrier tape. This circumstance can also be referred to as the first material tape system in the material tape system connection not having any fixing adhesive tape.In particular, the first material tape system and the second material tape system are connected to one another such that the connecting adhesive surface of the first connecting adhesive tape of the first material tape system is connected on a second side of the carrier tape of the second material tape system to the second end section of the carrier 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, by connecting the first material tape system to the second material tape system, the carrier tape of the first material tape system can be connected to the carrier tape of the second material tape system.

[0022] Due to the structure of the material tape system according to the invention, in particular due to the special connection of the fixing adhesive tape and the first connecting adhesive tape with the carrier tape, the material tape system can be used in a simple and time-saving manner in a material tape system composite, since in order to connect two material tape systems only the fixing adhesive tape has to be detached from the carrier tape and thereby a simple connection possibility is provided by the connecting adhesive surface of the first connecting adhesive tape.In particular, when a plurality of material tape systems are connected to one another in a material tape system assembly such that each pair of adjacent material tape systems comprises 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 on a second side of the carrier tape of the second material tape system to the second end section of the carrier 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. Due to the structure of the material tape system according to the invention, in particular a plurality of carrier tapes can be connected to one another particularly quickly.The material tape system according to the invention ensures, in particular, ease of handling, since no additional material needs to be provided to connect multiple carrier tapes, as the bonding surface of the first bonding adhesive tape is already provided by the material tape system. This is particularly advantageous compared to material tape systems known from the prior art, which have a carrier tape but no bonding adhesive tape according to the invention, since these often require additional adhesive tapes to connect carrier tapes.

[0023] The following advantages have been identified, particularly when using a material belt system in an automated robot applicator.

[0024] Thanks to the simple handling and time-saving connection of multiple material band systems, material changeover times, in particular the time between using a first material band system and a second material band system, have been significantly reduced. This is because once the carrier tape of a first material band system has been unwound from the roll core of the first material band system, the roll core of the first material band system can be removed from the robot applicator, the second material band system with the roll core can be inserted into the robot applicator, and the carrier tape of the first material band system can be connected to the carrier tape of the second material band system quickly and easily. This allows automated processes with automated robot applicators to be accelerated and made more efficient.

[0025] It has further been shown that with the aid of the material tape system according to the invention, process stability could be significantly increased, particularly when used in an automated robot applicator, since the material tape system according to the invention, particularly in a material tape system composite, can be guided consistently and predictably over time by the automated robot applicator. In particular, the high process stability is ensured by the fact that the carrier tapes of two adjacent material tape systems of a material tape system composite can be positioned particularly precisely relative to one another. The particularly precise positioning of the carrier tapes is ensured in particular by the first connecting adhesive tape, which is already attached to one end of a carrier and only needs to be connected to the second carrier tape.It has been found that an operator of the automated robot applicator positions two carrier tapes of two material tape systems according to the invention much more precisely relative to each other than is the case with material tape systems known from the prior art.

[0026] Furthermore, it has been shown that the material belt system according to the invention significantly increases process reliability, particularly when used in an automated robot applicator, since the connection between two carrier belts of two material belt systems according to the invention is mechanically much more robust than is the case with the prior art. In particular, it has been shown that two carrier belts of two material belt systems according to the invention are much more difficult to separate from each other than is the case with the prior art.

[0027] Furthermore, it has been found that when several material band systems according to the invention with a roll core are used in a robot applicator, when the carrier band of a first material band system of the plurality of material band systems has already been unwound from the roll core but is still connected to it, the robot applicator can be stopped, the carrier band of the first material band system can be connected to the carrier band of the second material band system of the plurality of material band systems, and the robot applicator can then be restarted so that the carrier band of the second material band system is unwound from the roll core. By using this procedure, an endless carrier band can be produced which has a plurality of carrier bands when a plurality of material band systems are used.Each time two carrier tapes are joined to produce the endless carrier tape, the entire length of each carrier tape, and thus, for example, the entire number of punched parts arranged on the carrier tape, can be used. This allows material to be saved compared to the prior art method, in particular by using all punched parts. Thus, the material tape system according to the invention enables particularly resource-saving processes. Furthermore, each time two carrier tapes are joined to produce the endless carrier tape, there is no need to rethread the material tape system into the robot applicator, thus enabling particularly time-efficient processes.

[0028] In summary, it can be said that the material belt system according to the invention simplifies handling, ensures time-efficient and resource-saving processes and increases process stability and process reliability.

[0029] In one embodiment, the material tape system comprises a release tape with a first side and a second side. When the fixing adhesive tape is connected to the carrier tape, the release tape is arranged between the fixing adhesive tape and the first connecting adhesive tape such 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 comprises a release layer. The release layer can be a release paper. Furthermore, the release tape can comprise a carrier layer. The carrier layer is preferably connected to the release layer. The release layer preferably has a surface facing away from the carrier layer, to which surface, in particular, pressure-sensitive adhesive surfaces, such as the connecting adhesive surface of the first connecting adhesive tape, can be connected and from which these pressure-sensitive adhesive surfaces can be particularly easily detached.In particular, the carrier layer ensures that the release tape is mechanically robust in its main extension plane, particularly with respect to tensile loads in the main extension plane. Furthermore, the release tape preferably has a first side and a second side. The carrier layer is preferably arranged on the first side of the release tape. The release layer is preferably arranged on the second side of the release tape. The release tape is arranged in particular between the fixing adhesive tape and the first connecting adhesive tape. The release tape preferably lies against the first end face of the first end section and thereby covers it, such that the first end face is protected from mechanical influences, such as elastic or plastic deformation of the first end face, such as cracks in the first end face. As already described, the fixing adhesive tape is connected to the carrier tape.The release tape is preferably arranged between the fixing adhesive tape and the first connecting adhesive tape such 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. In this case, 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 such 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.

[0030] In one embodiment, the release tape is connected on its first side to the fixing adhesive tape and on its second side to the bonding adhesive surface of the first bonding adhesive tape in such a way that when the fixing adhesive tape is detached from the carrier tape, the release tape detaches from the bonding adhesive surface. Because the release tape is connected on its first side to the fixing adhesive tape and on its second side to the bonding adhesive surface of the first bonding adhesive tape in such a way that when the fixing adhesive tape is detached from the carrier tape, the release tape detaches from the bonding adhesive surface, the bonding adhesive surface can be exposed by removing the fixing adhesive tape and the concomitant removal of the release tape. Exposure of the bonding adhesive surface can thus be ensured even if a release tape is provided.

[0031] In one embodiment, the bonding adhesive surface of the first bonding adhesive tape is covered by the release tape. Covering the bonding adhesive surface of the first bonding adhesive tape by the release tape ensures that the bonding adhesive surface is protected by the release tape, in particular from contamination. Preferably, the release tape is designed, arranged, and connected to the fixing adhesive tape such that, when the fixing adhesive tape is connected to the carrier tape, the bonding adhesive surface of the first bonding adhesive tape is directly covered by the release tape, i.e., the release tape rests against the bonding adhesive surface and completely covers it.

[0032] In one embodiment, a first adhesive force acting from the fixing adhesive surface onto the carrier tape is smaller than a second adhesive force acting from a connecting section of the fixing adhesive tape onto the release tape. Preferably, the second adhesive force acts from the third section of the plurality of sections of the adhesive surface of the adhesive layer of the fixing adhesive tape onto the release tape. Preferably, the first and second adhesive forces are each understood to be a force threshold that must be overcome in order to separate the corresponding elements from one another under a load perpendicular to the connecting surfaces of the individual elements. Preferably, the first adhesive force is a force threshold that must be overcome in order to separate the carrier tape and the fixing adhesive tape from one another, and the second adhesive force is a force threshold that must be overcome in order to separate the fixing adhesive tape and the release tape from one another.

[0033] In one embodiment, the second adhesive force acting on the release tape from the connecting portion of the fixing adhesive tape is greater than a third adhesive force acting on the release tape from the connecting adhesive surface of the first connecting adhesive tape. The third adhesive force is preferably understood to be a force threshold that must be overcome in order to separate 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 that must be overcome in order to separate the first connecting adhesive tape and the release tape from one another.

[0034] In one embodiment, the third adhesive force acting from the bonding surface of the first bonding adhesive tape onto the release tape is smaller than a fourth adhesive force acting from the bonding portion of the first bonding adhesive tape onto the first end portion of the carrier tape. The fourth adhesive force is preferably a force threshold that must be overcome in order to separate the corresponding elements from one another under a load perpendicular to the bonding surfaces of the individual elements. The fourth adhesive force is preferably a force threshold that must be overcome in order to separate the first bonding adhesive tape and the carrier tape from one another.

[0035] Preferably, the material tape system is configured such that when the material tape system is subjected to a tensile load perpendicular to the connecting surfaces of the individual elements, in which a tensile force acts on the fixing adhesive tape and an opposing tensile force acts on the first connecting adhesive tape, both the carrier tape and the fixing adhesive tape separate from each other, as do the connecting adhesive tape and the release tape, while both the fixing adhesive tape and the release tape, as well as the carrier tape and the first connecting adhesive tape, remain connected to each other. This can be achieved, in particular, by matching the adhesive strengths of the different pressure-sensitive adhesive surfaces to one another.

[0036] In particular, the pressure-sensitive adhesive strength of the different pressure-sensitive adhesive surfaces is coordinated with one another as follows. Preferably, a first strength threshold value of the bond between the fixing adhesive surface and the carrier tape is smaller than a second strength threshold value of the bond between the connecting portion of the fixing adhesive tape and the release tape. In particular, the second strength threshold value relates to the bond between the third portion of the plurality of portions 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 bond between the connecting portion of the fixing adhesive tape and the release tape is preferably greater than a third strength threshold value of the bond 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 bonding surface of the first bonding adhesive tape and the release tape is preferably smaller than a fourth strength threshold value of the connection between the connecting section of the first bonding adhesive tape and the first end section of the carrier tape. The first, second, third, and fourth strength threshold values ​​are preferably each strength threshold value that must be overcome in order to separate the corresponding elements from one another under a load perpendicular to the bonding surfaces of the individual elements and perpendicular to the first bonding adhesive tape extension direction.The first strength threshold is preferably a strength threshold that must be overcome in order to separate the carrier tape and the fixing adhesive tape from one another, the second strength threshold is preferably a strength threshold that must be overcome in order to separate the fixing adhesive tape and the release tape from one another, the third strength threshold is preferably a strength threshold that must be overcome in order to separate the first connecting adhesive tape and the release tape from one another, and the fourth strength threshold is a strength threshold that must be overcome in order to separate the first connecting adhesive tape and the carrier tape from one another.

[0037] The features, technical effects and / or advantages described in connection with the first, second, third and fourth adhesion 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 peel force, which describes the force threshold that must be overcome in order to peel one element off another element.For example, it is provided that if the outermost end of the fixing adhesive tape is first pulled upwards perpendicular to the connecting surfaces of the individual elements and perpendicular to the first connecting adhesive tape extension direction and then upwards and against the first connecting adhesive tape extension direction, both the carrier tape and the fixing adhesive tape and the connecting adhesive tape and the release tape are detached from one another due to the ratios of the first, second, third and fourth peeling forces, whereby both the fixing adhesive tape and the release tape and the carrier tape and the first connecting adhesive tape remain connected to one another.

[0038] In one embodiment, when the fixing adhesive tape is connected to the carrier tape, the connecting adhesive surface of the first connecting adhesive tape is arranged on the first side of the carrier tape. Preferably, the first connecting adhesive tape is wrapped around the first end section of the carrier tape. The first connecting adhesive tape can be arranged in a U-shape. Preferably, the first connecting adhesive tape encloses the first end section of the carrier tape such that the first end side is covered by the first connecting adhesive tape, so that the first end side is protected by the first connecting adhesive tape. Preferably, the third section of the plurality of sections of the adhesive surface is provided for the adhesive layer of the fixing adhesive tape.The third section forms, in particular, a pressure-sensitive adhesive surface with which the fixing adhesive tape is connected to a surface of a section of the carrier layer of the first connecting adhesive tape on the side of the carrier layer of the first connecting adhesive tape. The surface of the section of the carrier layer of the first connecting adhesive tape may itself be non-pressure-sensitive adhesive. However, the surface of the section of the carrier layer of the first connecting adhesive tape is preferably designed, compared to the surface of the section of the release layer, such 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 carrier tape. The material tape system preferably has no release tape if the fixing adhesive tape is connected to the carrier tape and the connecting adhesive surface of the first connecting adhesive tape is arranged on the first side of the carrier tape.This makes it possible to provide a particularly resource-saving material belt system.

[0039] In one embodiment, the first connecting adhesive tape extends in a first connecting adhesive tape extension direction away from the first end portion of the carrier tape, wherein an extension of the connecting portion of the first connecting adhesive tape in the connecting adhesive tape extension direction corresponds to between 20% and 40%, preferably between 30 and 35%, of an extension of the first connecting adhesive tape in the connecting adhesive tape extension direction.Because the extension of the connecting portion of the first connecting adhesive tape in the connecting adhesive tape extension direction corresponds to between 20% and 40%, preferably between 30 and 35%, of the extension of the first connecting adhesive tape in the connecting adhesive tape extension direction, both a mechanically robust overlapping connection between the carrier tape and the first connecting adhesive tape and a sufficiently large bonding surface of the first connecting adhesive tape for mechanically robust connections can be ensured. This effect is noticeable over an entire range from 20% to 40% and is particularly pronounced in a range from 30% to 35%.It has surprisingly been found that when the extension of the connecting section of the first connecting adhesive tape in the first connecting adhesive tape extension direction corresponds to 33% of the extension of the first connecting adhesive tape in the first connecting adhesive tape extension direction, the overlapping connection between the carrier tape and the first connecting adhesive tape and the mechanically robust connections can be particularly advantageously coordinated with one another by means of the connecting adhesive surface of the first connecting adhesive tape.

[0040] In one embodiment, the material tape system comprises a roll core with a circumferential outer surface, wherein the fixing adhesive tape has a connecting portion by which the fixing adhesive tape is connected, in particular releasably, to the outer surface. Because the fixing adhesive tape has the connecting portion by which the fixing adhesive tape is connected, in particular releasably, to the outer surface, the carrier tape can be connected to the roll core by its first end portion such that, in the rolled-up state, the first end portion of the carrier tape is arranged radially inward compared to the second end portion of the carrier tape.

[0041] In one embodiment, the material tape system comprises a second connecting adhesive tape with a connecting section, with which the second connecting adhesive tape on the first side of the carrier tape is connected to the second end section of the carrier tape, and with a connecting adhesive surface. The second connecting adhesive tape preferably has a connecting section and a connecting adhesive surface. With the connecting section, the second connecting adhesive tape is preferably connected on the first side of the carrier tape to the second end section of the carrier tape. The connection between the connecting section of the second connecting adhesive tape and the second end section of the carrier tape ensures that when the second connecting adhesive tape is connected to a further element, the carrier tape is connected to this further element via the second connecting adhesive tape.For example, the connection between the connecting section of the second connecting adhesive tape and the second end section of the carrier tape can ensure that the carrier tape is connected, for example, to a roll core of the material tape system or to a section of the carrier tape, in particular on the first side of the carrier tape, using the second connecting adhesive tape, in particular when the carrier tape is wound around the roll core. The second connecting adhesive tape preferably has a carrier layer and an adhesive layer. The carrier layer ensures that the second connecting adhesive tape is mechanically robust in its main extension plane, in particular with respect to tensile loads in the main extension plane. The adhesive layer is in particular connected to the carrier layer.The adhesive layer is preferably pressure-sensitively adhesive 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 having 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, adjacent to the first section, preferably forms an adhesive surface with which the second connecting adhesive tape is connected to the second end section of the carrier tape. The second connecting adhesive tape preferably extends in a second connecting adhesive tape extension direction.The second connecting adhesive tape preferably extends in the second connecting adhesive tape extension direction away from the second end portion of the carrier tape. It has proven particularly advantageous that an extension of the connecting portion of the second connecting adhesive tape in the second connecting adhesive tape extension direction of between 20% and 40%, preferably between 30 and 35%, corresponds to an extension of the second connecting adhesive tape in the second connecting adhesive tape extension direction, since this ensures both a mechanically robust overlapping connection between the carrier tape and the second connecting adhesive tape and a sufficiently large bonding surface of the second connecting adhesive tape for mechanically robust connections. This effect is noticeable over an entire range from 20% to 40% and is particularly pronounced in a range from 30% to 35%.Particularly preferably, the extension of the connecting portion of the second connecting adhesive tape in the second connecting adhesive tape extension direction corresponds to 33% of the extension of the second connecting adhesive tape in the second connecting adhesive tape extension direction. Surprisingly, it has been found that at 33%, the overlapping connection between the carrier tape and the second connecting adhesive tape and mechanically robust connections can be particularly advantageously coordinated using the connecting adhesive surface of the second connecting adhesive tape.

[0042] In one embodiment, the material tape system comprises a roll core with a circumferential outer surface, wherein the second connecting adhesive tape is connected to the connecting adhesive surface, in particular releasably, with the outer surface. Because the second connecting adhesive tape is connected to the connecting adhesive surface, in particular releasably, with the outer surface, the carrier tape can be connected to the roll core by its second end portion such that, in the rolled-up state, the second end portion of the carrier tape is arranged radially inward compared to the first end portion of the carrier tape.

[0043] In one embodiment, a plurality of punched parts are arranged on the first side of the carrier tape and / or a plurality of punched parts are arranged on the second side of the carrier 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 in particular to the case where a plurality of punched parts are arranged on the first side of the carrier tape and / or a plurality of punched parts are arranged on the second side of the carrier tape. In particular, a plurality of punched parts can be arranged exclusively on the first side of the carrier tape. Alternatively, a plurality of punched parts can be arranged exclusively on the second side of the carrier tape.Furthermore, a plurality of punched parts can be arranged on the first side of the carrier tape, and a plurality of punched parts can be arranged on the second side of the carrier tape. This allows for different arrangements of punched parts on the carrier tape. By arranging the punched parts differently on the carrier tape, the punched parts can be optimally arranged for the respective application. This allows for flexible material tape systems to be created.

[0044] According to a second aspect of the invention, the object mentioned above is achieved by a material tape system assembly having the features of patent claim 14. The material tape system assembly comprises a first material tape system according to the first aspect of the invention. The material tape system assembly comprises 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 on a second side of the carrier tape of the second material tape system to the second end section of the carrier tape of the second material tape system. This makes it possible to provide a mechanically robust connection between the first material tape system and the second material tape system.

[0045] In one embodiment, the connecting adhesive surface of the second connecting adhesive tape of the second material tape system is connected to the first end portion of the carrier tape of the first material tape system on the first side of the carrier tape of the first material tape system. This can further increase the mechanical robustness of the connection between the first material tape system and the second material tape system.

[0046] In one embodiment, the carrier tape of the first material tape system and the carrier tape of the second material tape system are arranged such that a first tangential surface running perpendicular to the bonding adhesive surface of the first bonding adhesive tape of the first material tape system runs along a first edge region of the first end section of the carrier tape of the first material tape system and along a first edge region of the second end section of the carrier 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 carrier tape of the first material tape system and along a second edge region of the second end section of the carrier tape of the second material tape system.This arrangement aligns the carrier tape of the first material tape system and the carrier tape of the second material tape system, which is particularly advantageous when using the material tape system composite in an automated robot applicator, as this increases process stability and process reliability.

[0047] In one embodiment, a first end face of the first end portion of the carrier tape of the first material tape system and a second end face of the second end portion of the carrier tape of the second material tape system abut one another. Because the first end face of the first end portion of the carrier tape of the first material tape system and the second end face of the second end portion of the carrier tape of the second material tape system abut one another, the carrier tape of the first material tape system and the carrier tape of the second material tape system can be positioned particularly precisely relative to one another.Precise positioning of the carrier tapes relative to one another is particularly advantageous when using the material tape system assembly in an automated robot applicator, since the guidance of the material tape system assembly through the robot applicator is simplified and, in particular, the probability of the material tape system assembly becoming caught in the robot applicator is significantly reduced.

[0048] The features, technical effects and / or advantages described in connection with the material band system according to the first aspect of the invention also apply at least analogously to the material band system composite according to the second aspect of the invention, so that a corresponding repetition is omitted at this point.

[0049] According to a third aspect of the invention, the object mentioned above is achieved by a method having the features of patent claim 18. The method is provided for producing a material tape system composite according to the second aspect of the invention. The method comprises the following steps: providing the first material tape system; providing the second material tape system; detaching the fixing adhesive tape from the carrier 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 portion of the carrier tape of the second material tape system on the second side of the carrier tape of the second material tape system.

[0050] In one embodiment, the method comprises the following step: connecting the connecting adhesive surface of the second connecting adhesive tape of the second material tape system to the first end portion of the carrier tape of the first material tape system on the first side of the carrier tape of the first material tape system.

[0051] Even if the method steps are described in a specific order, the present invention is not limited to this order. Rather, the individual method steps can be performed in any meaningful order, in particular at least partially in parallel.

[0052] The features, technical effects and / or advantages described in connection with the material band system according to the first aspect of the invention and in connection with the material band system composite according to the second aspect of the invention also apply at least analogously to the method according to the third aspect of the invention, so that a corresponding repetition is omitted at this point.

[0053] According to a fourth aspect of the invention, the object mentioned at the outset is achieved by a use having the features of patent claim 20. The use relates to a use of a material band 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 band system according to the first aspect of the invention, in connection with the material band 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 analogously to the use according to the fourth aspect of the invention, so that a corresponding repetition is omitted here.

[0054] Further features, advantages, and possible applications of the present invention will become apparent from the following description of the exemplary embodiments and the figures. All described and / or illustrated features, individually and in any combination, constitute the subject matter of the invention, regardless of their composition in the individual claims or their references. In the figures, the same reference numerals continue to represent the same or similar objects. Fig. 1 shows a schematic view of a first embodiment of a material belt system according to the invention, Fig. 2 shows a schematic view of a second embodiment of the material belt system according to the invention, Fig. 3 shows a schematic view of an embodiment of a material band system composite according to the invention, and Fig. 4 shows two schematic views of the embodiment of the material band system composite according to the invention in Fig. 3 in a top view ( Fig. 4 a) and in a view from below ( Fig. 4 b).

[0055] Fig. 1 shows a schematic view of a first embodiment of a material tape system 1 according to the invention. The material tape system 1 comprises a carrier tape 3, a fixing adhesive tape 5, a first connecting adhesive tape 7, a second connecting adhesive tape 9 and a separating tape 11.

[0056] The carrier tape 3 has a first end section 13 and a second end section 15. The carrier tape 3 extends from the first end section 13 to the second end section 15. The carrier tape 3 has a first side 17 and a second side 19 opposite the first side 17. The first end section 13 has a first end face 21, which in the first embodiment of the material tape system 1 according to the invention in the Fig. 1 is covered by the separating tape 11. The second end section 15 has a second end face 23, which in the first embodiment of the material tape system 1 according to the invention is in the state shown in Fig. 1. The first end face 21 is arranged opposite the second end face 23 in a carrier tape extension direction such that the first end face 21 and the second end face 23 point in opposite directions. The carrier tape 3 has a release layer 25, which in the first embodiment of the material tape system 1 according to the invention is a release paper, and a carrier layer 27 connected to the release layer 25. The release layer 25 has a surface facing away from the carrier layer 27 and has a section to which, in particular, pressure-sensitive adhesive surfaces can be connected and from which these pressure-sensitive adhesive surfaces can be particularly easily detached. The carrier layer 27 ensures that the carrier tape 3 is mechanically robust in its main extension plane, in particular with respect to tensile loads in the main extension plane. The release layer 25 is arranged on the first side 17 of the carrier tape 3.The carrier layer 27 is arranged on the second side 19 of the carrier tape 3. Because the separating layer 25 is arranged on the first side 17 of the carrier tape 3 and the carrier layer 27 is arranged on the second side 19 of the carrier tape 3, the carrier tape 3 can provide the functionality of the separating layer 25 on the first side 17 and the functionality of the carrier layer 27 on the second side 19. The carrier tape can be arranged around a . Fig. 1 be wound around the roll core of the material tape system 1, not shown.

[0057] The fixing adhesive tape 5 has a connecting section 29 and a fixing adhesive surface 31. The fixing adhesive tape 5 is releasably connected to the first end section 13 of the carrier tape 3, specifically to a section of the release layer 25 of the carrier tape 3, via the fixing adhesive surface 31 on the first side 17 of the carrier tape 3. The releasable connection between the fixing adhesive surface 31 of the fixing adhesive tape 5 and the first end section 13 of the carrier tape 3 ensures that the fixing adhesive tape 5 is connected to the carrier tape 3 and can be detached therefrom.In particular, the detachable connection between the fixing adhesive surface 31 of the fixing adhesive tape 5 and the section of the separating layer 25 of the carrier tape 3 ensures that the fixing adhesive tape 5 and the carrier tape 3 can be particularly easily separated from one another, in particular when the connection between the fixing adhesive surface 31 of the fixing adhesive tape 5 and the section of the separating layer 25 of the carrier tape 3 is to be removed. The connection between the fixing adhesive tape 5 and the carrier tape 3 ensures that the carrier tape 3 can be connected, for example, to a roll core of the material tape system 1 or to a section of the carrier tape 3, in particular on the first side 17 of the carrier tape 3, using the fixing adhesive tape 5, in particular when the carrier tape 3 is wound around the roll core.Detaching the fixing adhesive tape 5 from the carrier tape 3 ensures that the carrier tape 3 can be decoupled from the roll core of the material tape system 1 or from the section of the carrier tape 3, in particular on the first side 17 of the carrier tape 3, by detaching the fixing adhesive tape 5 from the carrier tape 3 during or after the detachment. The detachable connection between the fixing adhesive tape 5 and the carrier tape 3 thus ensures that the function of connecting the carrier tape 3, for example to the roll core of the material tape system 1 or to the section of the carrier tape 3, in particular on the first side 17 of the carrier tape 3, can be fulfilled by the fixing adhesive tape 5 and the structural design of the carrier tape 3 can be selected independently of this function.

[0058] The adhesive fixing tape 5 has a carrier layer 33 and an adhesive layer 35. The carrier layer 33 ensures that the adhesive fixing tape 5 is mechanically robust in its main extension plane, particularly with respect to tensile loads in the main extension plane. The adhesive layer 35 is bonded to the carrier layer 33. The adhesive layer 35 is pressure-sensitively adhesive and thus ensures that the adhesive fixing tape 5 can be bonded to other elements, such as the first end section 13 of the carrier tape 3 or to the release tape 11, or to both the first end section 13 and the release tape 11. The adhesive layer 35 of the adhesive fixing tape 5 forms an adhesive surface having multiple sections.A first section of the multiple sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 forms the fixing adhesive surface 31, with which the fixing adhesive tape 5 is detachably connected to the first end section 13 of the carrier tape 3. A second section of the multiple sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 forms an adhesive surface with which the fixing adhesive tape 5 can be detachably connected, for example, to a roll core of the material tape system 1 or to a section of the carrier tape 3, in particular on the first side 17 of the carrier tape 3. The second section is shown in FIG. Fig. 1 exposed. Furthermore, a third section of the plurality of sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 is provided. The third section is arranged between the first section and the second section and in Fig. 1 covered by the separating tape 11.

[0059] The first connecting adhesive tape 7 has a connecting section 37 and a connecting adhesive surface 39. With the connecting section 37, the first connecting adhesive tape 7 is connected to the first end section 13 of the carrier tape 3 on the second side 19 of the carrier tape 3, which is opposite the first side 17 of the carrier tape 3. The connection between the connecting section 37 of the first connecting adhesive tape 7 and the first end section 13 of the carrier tape 3 ensures that when the first connecting adhesive tape 7 is connected to a further element, the carrier tape 3 is connected to this further element via the first connecting adhesive tape 7. The connecting adhesive surface 39 is in the Fig. 1, the first embodiment of the material belt system 1 according to the invention is covered by the separating belt 11.

[0060] The first connecting adhesive tape 7 has a carrier layer 41 and an adhesive layer 43. The carrier layer 41 ensures that the first connecting adhesive tape 7 is mechanically robust in its main extension plane, in particular with respect to tensile loads in the main extension plane. The adhesive layer 43 is connected to the carrier layer 41. The adhesive layer 43 is pressure-sensitively adhesive and thus ensures that the first connecting adhesive tape 7 can be connected to other elements, such as the first end section 13 of the carrier tape 3 or to the release tape 11 or to both the first end section 13 and the release tape 11. The adhesive layer 43 of the first connecting adhesive tape 7 forms an adhesive surface having a plurality of sections. A first section of the plurality of sections of the adhesive surface of the adhesive layer 43 of the first connecting adhesive tape 7 forms the Fig. 1 connecting adhesive surface 39 of the first connecting adhesive tape 7 covered by the release tape 11. A second section of the plurality of sections of the adhesive surface of the adhesive layer 43 of the first connecting adhesive tape 7 adjacent to the first section forms an adhesive surface with which the first connecting adhesive tape 7 is connected to the first end section 13 of the carrier tape 3.

[0061] The first connecting adhesive tape 7 extends in a first connecting adhesive tape extension direction 45, the vectorial representation of which is arranged in the main extension plane of the first connecting adhesive tape 7. The first connecting adhesive tape 7 extends in the first connecting adhesive tape extension direction 45 away from the first end portion 13 of the carrier tape 3.It has proven particularly advantageous that an extension of the connecting section 37 of the first connecting adhesive tape 7 in the first connecting adhesive tape extension direction 45 of between 20% and 40%, preferably between 30 and 35%, corresponds to an extension of the first connecting adhesive tape 7 in the first connecting adhesive tape extension direction 45, since this ensures both a mechanically robust overlapping connection between the carrier tape 3 and the first connecting adhesive tape 7 and a sufficiently large connecting adhesive surface 39 of the first connecting adhesive tape 7 for mechanically robust connections. This effect can be observed over an entire range from 20% to 40% and is particularly pronounced in a range from 30% to 35%. In the in . Fig. 1, the extension of the connecting section 37 of the first connecting adhesive tape 7 in the first connecting adhesive tape extension direction 45 corresponds to 33% of the extension of the first connecting adhesive tape 7 in the first connecting adhesive tape extension direction 45. It has surprisingly been found that at 33% the overlapping connection between the carrier tape 3 and the first connecting adhesive tape 7 and mechanically robust connections can be particularly advantageously coordinated with one another using the connecting adhesive surface 39 of the first connecting adhesive tape 7.

[0062] The second connecting adhesive tape 9 has a connecting section 47 and a connecting adhesive surface 49. The connecting section 47 connects the second connecting adhesive tape 9 on the first side 17 of the carrier tape 3 to the second end section 15 of the carrier tape 3. The connection between the connecting section 47 of the second connecting adhesive tape 9 and the second end section 15 of the carrier tape 3 ensures that, when the second connecting adhesive tape 9 is connected to another element, the carrier tape 3 is connected to this another element via the second connecting adhesive tape 9.For example, the connection between the connecting section 47 of the second connecting adhesive tape 9 and the second end section 15 of the carrier tape 3 can ensure that the carrier tape 3 can be connected, for example, to a roll core of the material tape system 1 or to a section of the carrier tape 3, in particular on the first side 17 of the carrier tape 3, using the second connecting adhesive tape 9, in particular when the carrier tape 3 is wound around the roll core. The connecting adhesive surface 49 is in the form shown in FIG. Fig. 1 illustrated first embodiment of the material band system according to the invention.

[0063] The second connecting adhesive tape 9 has a carrier layer 51 and an adhesive layer 53. The carrier layer 51 ensures that the second connecting adhesive tape 9 is mechanically robust in its main extension plane, in particular with respect to tensile loads in the main extension plane. The adhesive layer 53 is bonded to the carrier layer 51. The adhesive layer 53 is pressure-sensitively adhesive and thus ensures that the second connecting adhesive tape 9 can be bonded to other elements. The adhesive layer 53 of the second connecting adhesive tape 9 forms an adhesive surface having a plurality of sections. A first section of the plurality of sections of the adhesive surface of the adhesive layer 53 of the second connecting adhesive tape 9 forms the connecting adhesive surface 49 of the second connecting adhesive tape 9.A second section of the plurality of sections of the adhesive surface of the adhesive layer 53 of the second connecting adhesive tape 9, adjacent to the first section, forms an adhesive surface with which the second connecting adhesive tape 9 is connected to the second end section 15 of the carrier tape 3.

[0064] The second connecting adhesive tape 9 extends in a second connecting adhesive tape extension direction 55, the vectorial representation of which is arranged in the main extension plane of the second connecting adhesive tape 9. The second connecting adhesive tape 9 extends in the second connecting adhesive tape extension direction 55 away from the second end portion 15 of the carrier tape 3.It has proven particularly advantageous that an extension of the connecting section 47 of the second connecting adhesive tape 9 in the second connecting adhesive tape extension direction 55 of between 20% and 40%, preferably between 30 and 35%, corresponds to an extension of the second connecting adhesive tape 9 in the second connecting adhesive tape extension direction 55, since this ensures both a mechanically robust overlapping connection between the carrier tape 3 and the second connecting adhesive tape 9 and a sufficiently large connecting adhesive surface 49 of the second connecting adhesive tape 9 for mechanically robust connections. This effect can be observed over an entire range from 20% to 40% and is particularly pronounced in a range from 30% to 35%. In the in . Fig. 1, the extension of the connecting section 47 of the second connecting adhesive tape 9 in the second connecting adhesive tape extension direction 55 corresponds to 33% of the extension of the second connecting adhesive tape 9 in the second connecting adhesive tape extension direction 55. It has surprisingly been found that at 33% the overlapping connection between the carrier tape 3 and the second connecting adhesive tape 9 and mechanically robust connections can be particularly advantageously coordinated with one another using the connecting adhesive surface 49 of the second connecting adhesive tape 9.

[0065] As already described, the carrier tape 3 can be connected to the roll core of the material tape system 1 or to a section of the carrier tape 3, in particular on the first side 17 of the carrier tape 3, using the second connecting adhesive tape 9, in particular when the carrier tape 3 is wound around the roll core. In particular, when the carrier tape 3 is wound around the roll core and the carrier tape 3 is connected to the roll core of the material tape system 1 using the fixing adhesive tape 5, the carrier tape 3 can be connected to the section of the carrier tape 3, in particular on the first side 17 of the carrier tape 3, using the second connecting adhesive tape 9.Alternatively, particularly when the carrier tape 3 is wound around the roll core and the carrier tape 3 is connected to the roll core of the material tape system 1 by means of the second connecting adhesive tape 9, the carrier tape 3 can be connected to the section of the carrier tape 3, in particular on the first side 17 of the carrier tape 3, by means of the fixing adhesive tape 5. These two alternatives ensure that the carrier tape 3 can be connected to the roll core and, at the same time, to itself, in particular to a section on the first side 17 of the carrier tape 3, so that the carrier tape 3 remains in the state of being wound around the roll core. When the carrier tape 3 is in the state of being wound around the roll core, the material tape system 1 can be stored in a particularly space-saving manner.To use the material tape system 1, when the carrier tape 3 is connected to the section of the carrier tape 3, in particular on the first side 17 of the carrier tape 3, by means of the second connecting adhesive tape 9, the second connecting adhesive tape 9 can be detached from the section of the carrier tape 3, and then the carrier tape 3 can be unwound from the roll core. When the carrier tape 3 is connected to the section of the carrier tape 3, in particular on the first side 17 of the carrier tape 3, by means of the fixing adhesive tape 5, to use the material tape system 1, the fixing adhesive tape 5 can be detached from the section of the carrier tape 3, and then the carrier tape 3 can be unwound from the roll core.In connection with these two alternatives, the separating layer 25 in particular has proven to be advantageous since it can have a section with which in particular the pressure-sensitive adhesive surfaces, such as the adhesive surface of the fixing adhesive tape 5, with which the fixing adhesive tape 5 can be detachably connected to the section of the carrier tape 3 on the first side 17 of the carrier tape 3, ie the second section of the plurality of sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5, or the connecting adhesive surface 49, can be connected and from which these pressure-sensitive adhesive surfaces can be particularly easily detached.

[0066] The release tape 11 has a release layer 57, which in the first embodiment of the material tape system 1 according to the invention is a release paper, and a carrier layer 59 connected to the release layer 57. The release layer 57 has a surface facing away from the carrier layer 59, to which surface, in particular, pressure-sensitive adhesive surfaces, such as the bonding adhesive surface 39 of the first bonding adhesive tape 7, can be bonded and from which these pressure-sensitive adhesive surfaces can be detached particularly easily. The carrier layer 59 ensures that the release tape 11 is mechanically robust in its main extension plane, in particular with respect to tensile loads in the main extension plane. Furthermore, the release tape 11 has a first side 61 and a second side 63. The carrier layer 59 is arranged on the first side 61 of the release tape 11. The release layer 57 is arranged on the second side 63 of the release tape 11.The separating tape 11 is arranged between the fixing adhesive tape 5 and the first connecting adhesive tape 7. The separating tape 11 lies against the first end face 21 of the first end section 13 and thereby covers it, so that the first end face 21 is protected from mechanical influences, such as elastic or plastic deformation of the first end face 21, such as cracks in the first end face 21. As already described, in the in . Fig. 1, the fixing adhesive tape 5 is connected to the carrier tape 3. The release tape 11 is arranged between the fixing adhesive tape 5 and the first connecting adhesive tape 7 such that the first section, which forms the fixing adhesive surface 31 of the fixing adhesive tape 5, the second section and the third section of the plurality of sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 face the first side 61 of the release tape 11. In this case, the third section of the plurality of sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 is covered by the release tape 11. Furthermore, the release tape 11 is arranged between the fixing adhesive tape 5 and the first connecting adhesive tape 7 such that the connecting adhesive surface 39 of the first connecting adhesive tape 7 faces the second side 63 of the release tape 11. The connecting adhesive surface 39 of the first connecting adhesive tape 7 is covered by the separating tape 11.

[0067] In the Fig. The first embodiment of the material tape system 1 according to the invention shown in Figure 1 is particularly advantageous in that the fixing adhesive tape 5 and the first connecting adhesive tape 7 are each connected to the carrier tape 3 in a specific manner. The fixing adhesive tape 5 and the first connecting adhesive tape 7 are connected to the carrier tape 3 in such a way that, when the fixing adhesive tape 5 is connected to the carrier tape 3, the connecting adhesive surface 39 of the first connecting adhesive tape 7 is covered. Furthermore, the fixing adhesive tape 5 and the first connecting adhesive tape 7 are connected to the carrier tape 3 in such a way that, when the fixing adhesive tape 5 is detached from the carrier tape 3, the connecting adhesive surface 39 of the first connecting adhesive tape 7 is exposed.

[0068] When the fixing adhesive tape 5 is bonded to the carrier tape 3, the bonding adhesive surface 39 of the first bonding adhesive tape 7 is covered, so that when the material tape system 1 is used, the first bonding adhesive tape 7 does not stick to objects to which it should not stick. Furthermore, when the bonding adhesive surface 39 of the first bonding adhesive tape 7 is covered, the bonding adhesive surface 39 is protected from contamination when the material tape system 1 is used.

[0069] Furthermore, when the fixing adhesive tape 5 is detached from the carrier tape 3, the connecting adhesive surface 39 of the first connecting adhesive tape 7 is exposed, so that by detaching the fixing adhesive tape 5 from the carrier tape 3, the connecting adhesive surface 39 can be specifically exposed in order to specifically connect it to other elements, such as, for example, to the connecting adhesive surface 49 of the second connecting adhesive tape 9 of another material tape system 1 or to the second end section 15 of the carrier tape 3 of the other material tape system 1 on the second side 19 of the carrier tape 3 of the other material tape system 1 or both to the connecting adhesive surface 49 of the second connecting adhesive tape 9 of the other material tape system 1 and to the second end section 15 of the carrier tape 3 of the other material tape system 1 on the second side 19 of the carrier tape 3 of the other material tape system 1.

[0070] In summary, the material tape system 1 ensures several functions through its structure and in particular through the fixing adhesive tape 5 and the interaction of the fixing adhesive tape 5 with the other elements of the material tape system 1. Firstly, the carrier tape 3 can be detachably attached to other elements using the fixing adhesive tape 5, such as a roller roller of the material tape system 1. Furthermore, the structural design of the carrier tape 3 can be selected independently of the function of detachably attaching the carrier tape 3 to other elements. This allows the carrier tape 3 to be designed particularly flexibly according to its intended use. For example, the carrier tape 3 can be designed to be particularly lightweight and at the same time mechanically robust, in particular tear-resistant.Furthermore, the design of the material tape system 1, and in particular the fixing adhesive tape 5, ensures the targeted covering and exposure of the connecting adhesive surface 39 of the first connecting adhesive tape 7, so that it is protected from contamination on the one hand and can be exposed as needed on the other. The material tape system 1 thus ensures that the carrier tape 3 can be mechanically robust and that the use of the material tape system 1 is particularly user-friendly. This user-friendliness is ensured in particular by the fact that the connecting adhesive surface 39 can be easily exposed by detaching the fixing adhesive tape 5 from the carrier tape 3.

[0071] As already described, the first embodiment of the material tape system 1 according to the invention comprises the release tape 11. The release tape 11 is designed, arranged, and connected to the fixing adhesive tape 5 such that, when the fixing adhesive tape 5 is connected to the carrier tape 3, the connecting adhesive surface 39 of the first connecting adhesive tape 7 is directly covered by the release tape 11, i.e., the latter rests against the connecting adhesive surface 39 and completely covers it. Furthermore, the release tape 11 is designed, arranged, and connected to the fixing adhesive tape 5 such that, when the fixing adhesive tape 5 is detached from the carrier tape 3, the connecting adhesive surface 39 of the first connecting adhesive tape 7 is exposed, i.e., the release tape 11 does not rest against the connecting adhesive surface 39 and does not cover it.The release tape 11 is connected on its first side 61 to the fixing adhesive tape 5 and on its second side 63 to the connecting adhesive surface 39 of the first connecting adhesive tape 7 in such a way that when the fixing adhesive tape 5 is detached from the carrier tape 3, the release tape 11 detaches from the connecting adhesive surface 39. Thus, the connecting adhesive surface 39 can be exposed by removing the fixing adhesive tape 5 and the concomitant removal of the release tape 11.

[0072] The first embodiment of the material tape system 1 according to the invention is particularly advantageous due to the arrangement of the carrier tape 3, the fixing adhesive tape 5, the connecting adhesive tape 7 and the separating tape 11 relative to one another and their interactions with one another, in particular due to the interaction of different pressure-sensitive adhesive surfaces whose pressure-sensitive adhesiveness is coordinated with one another.

[0073] The fixing adhesive tape 5 has the pressure-sensitive adhesive layer 35, which has the adhesive surface with the multiple sections. The first section of the multiple sections of the adhesive surface of the adhesive layer 35 forms the pressure-sensitive adhesive fixing surface 31, with which the fixing adhesive tape 5 is releasably connected on the first side 17 of the carrier tape 3 to the first end section 13 of the carrier tape 3. Here, the pressure-sensitive adhesive fixing surface 31 is connected to a section of the release layer 25 of the carrier tape 3, wherein the surface of this section of the release layer 25 is not pressure-sensitively adhesive, so that the pressure-sensitive adhesive fixing surface 31 can be particularly easily detached from this surface of the section of the release layer 25.

[0074] Between the first section and the second section (which is in Fig. 1 exposed) of the plurality of sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 is provided. The third section of the plurality of sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 is provided. The third section forms a pressure-sensitive adhesive surface with which the fixing adhesive tape 5 is connected on the first side 61 of the release tape 11 to a surface of the carrier layer 59 of the release tape 11. The surface of the carrier layer 59 of the release tape 11 is not itself pressure-sensitively adhesive. However, compared to the surface of the section of the release layer 25, the surface of the carrier layer 59 of the release tape 11 is designed such that the material bond between the fixing adhesive tape 5 and the release tape 11 is mechanically more robust than the material bond between the fixing adhesive tape 5 and the carrier tape 3.

[0075] The first connecting adhesive tape 7 has the pressure-sensitive adhesive layer 43, which has the adhesive surface with the multiple sections. The first section of the multiple sections of the adhesive surface of the adhesive layer 43 forms the pressure-sensitive adhesive connecting surface 39, which Fig. 1 is covered by the release tape 11. Here, the pressure-sensitive adhesive bonding surface 39 on the second side 63 of the release tape 11 is bonded to a surface of the release layer 57 of the release tape 11. The surface of the release layer 57 of the release tape 11 is not pressure-sensitively adhesive. Compared to the surface of the carrier layer 59 of the release bath 11, the surface of the release layer 57 of the release tape 11 is designed such that the material bond between the fixing adhesive tape 5 and the release tape 11 is mechanically more robust than the material bond between the release tape 11 and the first connecting adhesive tape 7.

[0076] In the first embodiment of the material tape system 1 according to the invention, the pressure-sensitive adhesiveness of the different pressure-sensitive adhesive surfaces is coordinated with one another as follows. A first adhesive force acting from the fixing adhesive surface 31 onto the carrier tape 3 is smaller than a second adhesive force acting from the connecting section 29 of the fixing adhesive tape 5 onto the release tape 11. The second adhesive force acts from the third section of the multiple sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 onto the release tape 11. Furthermore, the second adhesive force acting from the connecting section 29 of the fixing adhesive tape 5 onto the release tape 11 is greater than a third adhesive force acting from the connecting adhesive surface 39 of the first connecting adhesive tape 7 onto the release tape 11.Furthermore, the third adhesive force acting from the connecting adhesive surface 39 of the first connecting adhesive tape 7 onto the release tape 11 is smaller than a fourth adhesive force acting from the connecting portion 37 of the first connecting adhesive tape 7 onto the first end portion 13 of the carrier tape 3.

[0077] The first, second, third and fourth adhesive forces are each a force threshold that must be overcome in order to hold the corresponding elements in the image plane of the Fig. 1 and perpendicular to the first connecting adhesive tape extension direction 45. The first adhesive force is a force threshold that must be overcome in order to separate the carrier tape 3 and the fixing adhesive tape 5 from each other, the second adhesive force is a force threshold that must be overcome in order to separate the fixing adhesive tape 5 and the release tape 11 from each other, the third adhesive force is a force threshold that must be overcome in order to separate the first connecting adhesive tape 7 and the release tape 11 from each other, and the fourth adhesive force is a force threshold that must be overcome in order to separate the first connecting adhesive tape 7 and the carrier tape 3 from each other.

[0078] If the material band system 1 is subjected to a tensile load in the image plane of the Fig. 1 and perpendicular to the first connecting adhesive tape extension direction 45, by a tensile force acting on the fixing adhesive tape 5 and an oppositely acting tensile force acting on the first connecting adhesive tape 7, both the carrier tape 3 and the fixing adhesive tape 5 and the connecting adhesive tape 7 and the release tape 11 detach from each other, wherein both the fixing adhesive tape 5 and the release tape 11 and the carrier tape 3 and the first connecting adhesive tape 7 remain connected to each other.

[0079] Due to the geometric structure of the first embodiment of the material tape system 1 according to the invention, the ratios of the adhesive forces to one another ensure the desired result of the described release of the individual elements. The first embodiment of the material tape system 1 according to the invention is also constructed such that the pressure-sensitive adhesive strength of the different pressure-sensitive adhesive surfaces is coordinated with one another as follows. A first strength threshold value of the connection between the fixing adhesive surface 31 and the carrier tape 3 is smaller than a second strength threshold value of the connection between the connecting section 29 of the fixing adhesive tape 5 and the release tape 11. The second strength threshold value relates to the connection between the third section of the multiple sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 and the release tape 11.Furthermore, the second strength threshold value of the connection between the connecting section 29 of the fixing adhesive tape 5 and the separating tape 11 is greater than a third strength threshold value of the connection between the connecting adhesive surface 39 of the first connecting adhesive tape 7 and the separating tape 11. Furthermore, the third strength threshold value of the connection between the connecting adhesive surface 39 of the first connecting adhesive tape 7 and the separating tape 11 is smaller than a fourth strength threshold value of the connection between the connecting section 37 of the first connecting adhesive tape 7 and the first end section 13 of the carrier tape 3. The first, second, third and fourth strength threshold values ​​are each to be understood as strength threshold values ​​that must be overcome in order to secure the corresponding elements under a load in the image plane of the . Fig. 1 and perpendicular to the first bonding adhesive tape extension direction 45. The first strength threshold is a strength threshold that must be overcome in order to separate the carrier tape 3 and the fixing adhesive tape 5 from each other, the second strength threshold is a strength threshold that must be overcome in order to separate the fixing adhesive tape 5 and the release tape 11 from each other, the third strength threshold is a strength threshold that must be overcome in order to separate the first bonding adhesive tape 7 and the release tape 11 from each other, and the fourth strength threshold is a strength threshold that must be overcome in order to separate the first bonding adhesive tape 7 and the carrier tape 3 from each other.

[0080] The features, technical effects and / or advantages described in connection with the first, second, third and fourth adhesive force as well as in connection with the first, second, third and fourth strength threshold value also apply at least analogously to a first, second, third and fourth peel force, which describes the force threshold that must be overcome in order to peel one element off another element. If, for example, in the first embodiment of the material band system 1 according to the invention, the Fig. 1 extreme left end of the fixing tape 5 in the image plane of the Fig. 1 is first pulled upwards perpendicular to the first connecting adhesive tape extension direction 45 and then upwards and counter to the first connecting adhesive tape extension direction 45, due to the ratios of the first, second, third and fourth peeling forces to one another, both the carrier tape 3 and the fixing adhesive tape 5 and the connecting adhesive tape 7 and the separating tape 11 separate from one another, wherein both the fixing adhesive tape 5 and the separating tape 11 and the carrier tape 3 and the first connecting adhesive tape 7 remain connected to one another.

[0081] As already described, the material tape system 1 can have a roll core with a circumferential outer surface. The fixing adhesive tape 5 can be connected to the outer surface by the connecting section 29, in particular to the second section of the multiple sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5. Alternatively, the second connecting adhesive tape 9 can be releasably connected to the circumferential outer surface of the roll core by the connecting adhesive surface 49.

[0082] Fig. Figure 2 shows a schematic view of a second embodiment of the material tape system 1 according to the invention. The material tape system 1 comprises the carrier tape 3, the fixing adhesive tape 5, the first connecting adhesive tape 7 and the second connecting adhesive tape 9. In comparison to the first embodiment of the material tape system 1 according to the invention in Fig. 1, the material tape system 1 according to the second embodiment does not have a release tape 11. In particular, the arrangement of the carrier tape 3, the fixing adhesive tape 5, and the first connecting adhesive tape 7 provided in the second embodiment of the material tape system 1 according to the invention ensures that a release tape 11, as provided in the first embodiment of the material tape system 1 according to the invention, can be dispensed with. Thus, the second embodiment of the material tape system 1 according to the invention represents a particularly resource-saving alternative. Just as in the first embodiment of the material tape system 1 according to the invention, the release layer 25 of the carrier tape 3 in the second embodiment of the material tape system 1 according to the invention is a release paper.

[0083] Also in the second embodiment of the material tape system 1 according to the invention, the fixing adhesive tape 5 and the first connecting adhesive tape 7 are connected to the carrier tape 3 in such a way that when the fixing adhesive tape 5 is connected to the carrier tape 3, the connecting adhesive surface 39 of the first connecting adhesive tape 7 is covered, and when the fixing adhesive tape 5 is detached from the carrier tape 3, the connecting adhesive surface 39 of the first connecting adhesive tape 7 is exposed. As in Fig. 2, when the fixing adhesive tape 5 is connected to the carrier tape 3, the connecting adhesive surface 39 of the first connecting adhesive tape 7 is arranged on the first side 17 of the carrier tape 3. The arrangement of the connecting adhesive surface 39 of the first connecting adhesive tape 7 on the first side 17 of the carrier tape 3 can be as in Fig. 2, by wrapping the first connecting adhesive tape 7 around the first end portion 13 of the carrier tape. The first connecting adhesive tape 7 is arranged in a U-shape and encloses the first end portion 13 of the carrier tape 3 such that the first end face 21 is covered by the first connecting adhesive tape 7.

[0084] The fixing adhesive tape 5 has the pressure-sensitive adhesive layer 35, which has the adhesive surface with the multiple sections. The first section of the multiple sections of the adhesive surface of the adhesive layer 35 forms the pressure-sensitive adhesive fixing surface 31, with which the fixing adhesive tape 5 is releasably connected on the first side 17 of the carrier tape 3 to the first end section 13 of the carrier tape 3. Here, the pressure-sensitive adhesive fixing surface 31 is connected to a section of the release layer 25 of the carrier tape 3, wherein the surface of this section of the release layer 25 is not pressure-sensitively adhesive, so that the pressure-sensitive adhesive fixing surface 31 can be particularly easily detached from this surface of the section of the release layer 25.

[0085] Between the first section and the second section (which is in Fig. 2 exposed) of the plurality of sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 is provided. The third section of the plurality of sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 is provided. The third section forms a pressure-sensitive adhesive surface with which the fixing adhesive tape 5 is connected to a surface of a section of the carrier layer 41 of the first connecting adhesive tape 7 on the side of the carrier layer 41 of the first connecting adhesive tape 7. The surface of the section of the carrier layer 41 of the first connecting adhesive tape 7 is not itself pressure-sensitively adhesive. However, the surface of the section of the carrier layer 41 of the first connecting adhesive tape 7 is designed in comparison to the surface of the section of the separating layer 25 such that the material bond between the fixing adhesive tape 5 and the first connecting adhesive tape 7 is mechanically more robust than the material bond between the fixing adhesive tape 5 and the carrier tape 3.

[0086] The first connecting adhesive tape 7 has the pressure-sensitive adhesive layer 43, which has the adhesive surface with the multiple sections. The first section of the multiple sections of the adhesive surface of the adhesive layer 43 forms the pressure-sensitive adhesive connecting surface 39, which Fig. 2 is covered by a surface of a section of the release layer 25 of the carrier tape 3. Here, the pressure-sensitive adhesive bonding surface 39 on the first side 17 of the carrier tape 3 is bonded to the surface of the section of the release layer 25 of the carrier tape 3 that is arranged at the first end section 13 of the carrier tape 3. The surface of the section of the release layer 25 is not pressure-sensitively adhesive. Compared to the surface of the section of the carrier layer 41 of the first adhesive bonding tape 7 facing the fixing tape 5, the surface of the section of the release layer 25 at the first end section 13 is designed such that the material bond between the fixing tape 5 and the first adhesive bonding tape 7 is mechanically more robust than the material bond between the first adhesive bonding tape 7 and the carrier tape 3 on the first side 17 of the carrier tape 3.The second section of the plurality of sections of the adhesive surface of the adhesive layer 43 of the first connecting adhesive tape 7 is arranged on the second side 19 of the carrier tape 3 and forms a pressure-sensitive adhesive surface with which the first connecting adhesive tape 7 is connected to a surface of a section of the carrier layer 27 of the carrier tape 3 at the first end section 13 of the carrier tape 3.

[0087] The surface of the section of the carrier layer 27 of the carrier tape 3 at the first end section 13 of the carrier tape 3 on the second side 19 of the carrier tape 3 is designed in comparison to the surface of the section of the separating layer 25 of the carrier tape 3 at the first end section 13 of the carrier tape 3 on the first side 17 of the carrier tape 3 such that the material bond between the carrier tape 3 and the first connecting adhesive tape 7 on the second side 19 of the carrier tape 3 is mechanically more robust than the material bond between the carrier tape 3 and the first connecting adhesive tape 7 on the first side 17 of the carrier tape 3.

[0088] In the second embodiment of the material tape system 1 according to the invention, the pressure-sensitive adhesiveness of the different pressure-sensitive adhesive surfaces is coordinated with one another as follows. A first adhesive force acting from the fixing adhesive surface 31 onto the carrier tape 3 is smaller than a second adhesive force acting from the connecting section 29 of the fixing adhesive tape 5 onto the first connecting adhesive tape 7. In this case, the second adhesive force acts from the third section of the multiple sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 onto the first connecting adhesive tape 7. Furthermore, the second adhesive force acting from the connecting section 29 of the fixing adhesive tape 5 onto the first connecting adhesive tape 7 is greater than a third adhesive force acting from the connecting adhesive surface 39 of the first connecting adhesive tape 7 onto the first end section 13 of the carrier tape 13.Furthermore, the third adhesive force acting from the connecting adhesive surface 39 of the first connecting adhesive tape 7 onto the first end portion 13 of the carrier tape 3 is smaller than a fourth adhesive force acting from the connecting portion 37 of the first connecting adhesive tape 7 onto the first end portion 13 of the carrier tape 3.

[0089] The first, second, third and fourth adhesive forces are each a force threshold that must be overcome in order to hold the corresponding elements in the image plane of the Fig. 2 and perpendicular to the first connecting adhesive tape extension direction 45. The first adhesive force is a force threshold that must be overcome in order to separate the carrier tape 3 and the fixing adhesive tape 5 from one another, the second adhesive force is a force threshold that must be overcome in order to separate the fixing adhesive tape 5 and the first connecting adhesive tape 7 from one another, the third adhesive force is a force threshold that must be overcome in order to separate the first connecting adhesive tape 7 and the carrier tape 3 on the first side 17 of the carrier tape 3, and the fourth adhesive force is a force threshold that must be overcome in order to separate the first connecting adhesive tape 7 and the carrier tape 3 on the second side 19 of the carrier tape 3.

[0090] If the material band system 1 is subjected to a tensile load in the image plane of the Fig. 1 and perpendicular to the first connecting adhesive tape extension direction 45, by applying a tensile force to the fixing adhesive tape 5 and an oppositely acting tensile force to the first connecting adhesive tape 7 on the second side 19 of the carrier tape 3, both the carrier tape 3 and the fixing adhesive tape 5 detach from each other, as well as the first connecting adhesive tape 7 and the carrier tape 3 on the first side 17 of the carrier tape 3 detach from each other, wherein initially both the fixing adhesive tape 5 and the first connecting adhesive tape 7 as well as the carrier tape 3 and the first connecting adhesive tape 7 on the second side 19 of the carrier tape 3 remain connected to each other. Subsequently, the fixing adhesive tape 5 can be detached from the first connecting adhesive tape 7 and the Fig. 2, the section of the first connecting adhesive tape 7 arranged on the first side 17 of the carrier tape 3 can be folded over in the direction of the first connecting adhesive tape extension direction 45, so that the first connecting adhesive tape 7 extends along the first connecting adhesive tape extension direction 45. By removing the fixing adhesive tape 5 and folding over the first connecting adhesive tape 7, the connecting adhesive surface 39 of the first connecting adhesive tape 7 can be exposed.

[0091] Due to the geometric structure of the second embodiment of the material tape system 1 according to the invention, the ratios of the adhesive forces to one another ensure the desired result of the described release of the individual elements. The second embodiment of the material tape system 1 according to the invention is also constructed such that the pressure-sensitive adhesive strength of the different pressure-sensitive adhesive surfaces is coordinated with one another as follows. A first strength threshold value of the bond between the fixing adhesive surface 31 and the carrier tape 3 is smaller than a second strength threshold value of the bond between the connecting section 29 of the fixing adhesive tape 5 and the first connecting adhesive tape 7. The second strength threshold value relates to the bond between the third section of the multiple sections of the adhesive surface of the adhesive layer 35 of the fixing adhesive tape 5 and the first connecting adhesive tape 7.Furthermore, the second strength threshold value of the connection between the connecting section 29 of the fixing adhesive tape 5 and the first connecting adhesive tape 7 is greater than a third strength threshold value of the connection between the connecting adhesive surface 39 of the first connecting adhesive tape 7 and the first end section 13 of the carrier tape 13. Furthermore, the third strength threshold value of the connection between the connecting adhesive surface 39 of the first connecting adhesive tape 7 and the first end section 13 of the carrier tape 13 is smaller than a fourth strength threshold value of the connection between the connecting section 37 of the first connecting adhesive tape 7 and the first end section 13 of the carrier tape 3. The first, second, third and fourth strength threshold values ​​are each to be understood as strength threshold values ​​that must be overcome in order to secure the corresponding elements under a load in the image plane of the . Fig. 2 and perpendicular to the first connecting adhesive tape extension direction 45. The first strength threshold is a strength threshold that must be overcome in order to separate the carrier tape 3 and the fixing adhesive tape 5 from one another, the second strength threshold is a strength threshold that must be overcome in order to separate the fixing adhesive tape 5 and the first connecting adhesive tape 7 from one another, the third strength threshold is a strength threshold that must be overcome in order to separate the first connecting adhesive tape 7 and the carrier tape 3 on the first side 17 of the carrier tape 3, and the fourth strength threshold is a strength threshold that must be overcome in order to separate the first connecting adhesive tape 7 and the carrier tape 3 on the second side 19 of the carrier tape 3.

[0092] The features, technical effects and / or advantages described in connection with the first, second, third and fourth adhesive force as well as in connection with the first, second, third and fourth strength threshold value also apply at least analogously to a first, second, third and fourth peel force, which describes the force threshold that must be overcome in order to peel one element off another element. If, for example, in the second embodiment of the material band system 1 according to the invention, the Fig. 2 extreme right end of the fixing tape 5 in the image plane of the Fig. 2 is first pulled upwards perpendicular to the first connecting adhesive tape extension direction 45 and then upwards and counter to the first connecting adhesive tape extension direction 45, due to the ratios of the first, second, third and fourth peeling forces to one another, first the fixing adhesive tape 5 and the first connecting adhesive tape 7 detach from one another and, together therewith, in particular simultaneously therewith, the first connecting adhesive tape 7 and the carrier tape 3 on the first side 17 of the carrier tape 3 and then the fixing adhesive tape 5 and the carrier tape 3 detach from one another, wherein the first connecting adhesive tape 7 and the carrier tape 3 remain connected to one another on the second side 19 of the carrier tape 3.

[0093] The features, technical effects and / or advantages described in connection with the first embodiment of the material band system 1 according to the invention also apply at least analogously to the second embodiment of the material band system according to the invention.

[0094] Fig. 3 shows a schematic view of an embodiment of a material belt system composite 65 according to the invention. Fig. 4 shows two schematic views of the embodiment of the material band system composite 65 according to the invention in Fig. 3 in a top view ( Fig. 4 a) and in a view from below ( Fig. 4 b). The material tape system composite 65 comprises a first material tape system 1 according to a third embodiment of the material tape system 1 according to the invention and a second material tape system 1 according to the third embodiment of the material tape system 1 according to the invention. The connecting adhesive surface 39 of the first connecting adhesive tape 7 of the first material tape system 1 is connected on a second side 19 of the carrier tape 3 of the second material tape system 1 to the second end section 15 of the carrier tape 3 of the second material tape system 1. The connecting adhesive surface 49 of the second connecting adhesive tape 9 of the second material tape system 1 is connected to the first end section 13 of the carrier tape 3 of the first material tape system 1 on the first side 17 of the carrier tape 3 of the first material tape system 1.

[0095] As already described, the Fig. 3, the material tape system assembly 65 comprises the first material tape system 1 and the second material tape system 1, each according to the third embodiment of the material tape system 1 according to the invention. When the third embodiment of the material tape system 1 according to the invention is used, the first end section 13 of the carrier tape 3 of the first material tape system 1 is arranged between the second end section 15 of the carrier tape 3 of the second material tape system 1 and the connecting adhesive surface 49 of the second connecting adhesive tape 9, and the second end section 15 of the carrier tape 3 of the second material tape system 1 is arranged between the first end section 13 of the carrier tape 3 of the first material tape system 1 and the connecting adhesive surface 39 of the first connecting adhesive tape 7. This provides a particularly space-saving material tape system assembly 65.When the first or second embodiment of the material band system 1 according to the invention is used, the first end face 21 of the first end section 13 of the carrier band 3 of the first material band system 1 and the second end face 23 of the second end section 15 of the carrier band 3 of the second material band system 1 can abut one another. As a result, the carrier band 3 of the first material band system 1 and the carrier band 3 of the second material band system 1 are aligned, which is particularly advantageous when using the material band system assembly 65 in an automated robot applicator, since the guidance of the material band system assembly 65 through the robot applicator is simplified and, in particular, the probability of the material band system assembly 65 becoming caught in the robot applicator is significantly reduced.

[0096] The first end portion 13 of the carrier tape 11 has a first edge region 67 and a second edge region 69. The second end portion 15 of the carrier tape 11 has a first edge region 71 and a second edge region 73.The carrier tape 3 of the first material tape system 1 and the carrier tape 3 of the second material tape system 1 are arranged such that a first tangential surface running perpendicular to the connecting adhesive surface 39 of the first connecting adhesive tape 7 of the first material tape system 1 runs along the first edge region 67 of the first end section 13 of the carrier tape 3 of the first material tape system 1 and along a first edge region 71 of the second end section 15 of the carrier tape 3 of the second material tape system 1 and a second tangential surface running parallel to the first tangential surface runs along the second edge region 69 of the first end section 13 of the carrier tape 3 of the first material tape system 1 and along the second edge region 73 of the second end section 15 of the carrier tape 3 of the second material tape system 1.Due to this arrangement, the carrier tape 3 of the first material tape system 1 and the carrier tape 3 of the second material tape system 1 are aligned, which is particularly advantageous when using the material tape system composite 65 in an automated robot applicator.

[0097] In the Fig. 3 and Fig.In the embodiment of the material strip system composite 65 according to the invention shown in Figure 4, a plurality of punched parts 75 are arranged on the first side 17 of each carrier strip 3. In other, not shown, embodiments of the material strip system composite 65 according to the invention, a plurality of punched parts 75 can be arranged exclusively on the second side 19 of the carrier strip 3. In further, not shown, embodiments of the material strip system composite 65 according to the invention, a plurality of punched parts 75 can be arranged both on the first side 17 of the carrier strip 3 and on the second side 19 of the carrier strip 3. Thus, different arrangements of punched parts 75 can be provided on the carrier strip 3. By different arrangements of punched parts 75 on the carrier strip 3, the punched parts 75 can be optimally arranged for the corresponding application.This allows flexible material belt systems 1 and material belt system composites 65 to be provided.

[0098] As already described, the detachable connection between the fixing adhesive tape 5 and the carrier tape 3 ensures that the function of connecting the carrier tape 3, for example to the roll core of the material tape system 1 or to the section of the carrier tape 3, in particular on the first side 17 of the carrier tape 3, can be fulfilled by the fixing adhesive tape 5, and the structural design of the carrier tape 3 can be selected independently of this function. This has proven particularly advantageous in the case in which a plurality of punched parts 75 are arranged on the first side 17 of the carrier tape 3 and / or a plurality of punched parts 75 are arranged on the second side 19 of the carrier tape 3, since in this case the carrier tape 3 can be structurally adapted to the plurality of punched parts 75.

[0099] The separating layer 25 has proven to be particularly advantageous since it can have a section with which in particular the pressure-sensitive adhesive surfaces, such as the adhesive surface of the fixing adhesive tape 5, with which the fixing adhesive tape 5 can be detachably connected to the section of the carrier tape 3 on the first side 17 of the carrier tape 3, or the connecting adhesive surface 49, can be connected and from which these pressure-sensitive adhesive surfaces can be particularly easily detached, in particular when the material tape system 1 is to be used, for example, in an automated robot applicator for applying a large number of punched parts 75.

[0100] The material tape system composite 65 is manufactured as follows. The first material tape system 1 and the second material tape system 1 are prepared. The fixing adhesive tape 5 is then detached from the carrier tape 3 of the first material tape system 1. The connecting adhesive surface 39 of the first connecting adhesive tape 7 of the first material tape system 1 is then connected to the second end section 15 of the carrier tape 3 of the second material tape system 1 on the second side 19 of the carrier tape 3 of the second material tape system 1. The connecting adhesive surface 49 of the second connecting adhesive tape 9 of the second material tape system 1 is then connected to the first end section 13 of the carrier tape 3 of the first material tape system 1 on the first side 17 of the carrier tape 3 of the first material tape system 1.

[0101] The features, technical effects and / or advantages described in connection with the first embodiment of the material band system 1 according to the invention and those described in connection with the second embodiment of the material band system 1 according to the invention also apply at least analogously to the third embodiment of the material band system 1 according to the invention and to the embodiment of the material band system composite 65 according to the invention.

[0102] Additionally, it should be noted that "comprising" does not exclude other elements or steps, and "a" or "an" does not exclude a plurality.
