For example, objects for labeling are provided with labels that were previously printed. It is also known to mark rubber tires by application of colored dots. In this way, certain characteristics of the tires for individuals or automatic detection systems can be easily and quickly identified. The respective identification may contain different information, for example simply a specific color or a two-dimensional code containing a large amount of information.

By the WO 2015/118155 A1 It is known to ablate parts of rubber tires by means of laser radiation in order to produce a visible marking. The structure of the tire is thereby changed.

By the WO 2005/000714 A1 a device is known by means of which parts of rubber tires can be removed by means of laser radiation in order to create a visible marking.

By the DE 20 2015 009 105 U1 It is known to structure a surface of a tire so that only by the resulting geometry, a two-dimensional code of different bright appearing elements of the same material is created.

By the US 5 603 796 A a method is known, are provided in the identification body by means of laser radiation with an identification and then applied to car tires. The laser beam impinges on a surface which is remote from an adhesive surface, with which the identification body is then attached to the tire.

By the US 5 047 110 A discloses a method, an apparatus and a carrier body for carrying out thermal transfer printing on tires. In this case, coating material is transferred from a carrier body under the action of heat of a punch on the tire. The transferred print image results from the shape of the stamp or the shape of the coating on the carrier body.

By the US 2003/0 201 202 A1 a method is known, processed in the identification body individually by means of laser radiation and then arranged on a support body, wound, unwound, cleaned and rewound.

In particular, then in the case of a faulty identification, the entire object does not have to be discarded, but the faulty identification can be removed and replaced by a correct identification. Another advantage is preferred in that any objects can be marked, provided that the identification body can be attached to it. In particular, for tires offers the advantage that the application of identification bodies is a proven method.

The following is a method of applying a label 01 on an object 02 described. This object 02 is preferably made of at least one rubber or at least one elastomer. In particular, a surface on which the marking 01 is to be applied, preferably made of at least one rubber or at least one elastomer. Under rubber are to be understood in particular vulcanizates of natural rubber and / or synthetic rubber. The object 02 has, for example, additional components of other materials. The object 02 is preferred as a tire 02 formed, in particular as a rubber tire 02 , For example, the object is 02 as vehicle tires 02 educated. Tires are for example as solid tires 02 or solid rubber tires 02 trained or as air-filled tires 02 educated. tires 02 For example, have additional components that are formed for example of other material, such as metal. The marking 01 for example, on a flank of the tire 02 applied.

The marking 01 preferably has a matrix code 04 on. A marking body is preferred 03 especially permanently with the object 02 connected. The identification body 03 preferably prefers or in combination with the object 02 the marking 01 In particular, the identification body 03 prefers a matrix code 04 on, for example, at the same time the matrix code 04 the marking 01 is. The marking 01 has in particular a labeling structure. This identification structure preferably has the at least one matrix code 04 on. The identification structure has alternatively or additionally further components. The identification structure alternatively or additionally has at least one ornamental component which serves for a decoration.

The one in the matrix code 04 coded information content is preferably read by means of a reading device, for example by means of an external device, in particular optically readable. Such a reading device has at least one sensor, which is designed, for example, as an optical sensor. For example, matrix codes can be captured using a corresponding camera, such as those available and / or common in cell phones or portable computers or as accessories for computers. This offers the advantage that the information provided can be transmitted in a particularly simple manner, in particular automatically and, for example, does not have to be input manually or has to be converted into machine-readable data by means of letter recognition software. In particular, this reduces the susceptibility to errors and saves time. The matrix code 04 can still be used without error by error correction functions despite partially lacking transmission. In addition, only a binary recognition of individual elements and no distinction of a variety of elements is necessary.

Preferably, the method and / or the carrier body is characterized 09 and / or the marking 01 additionally or alternatively by indicating that the matrix code 04 as a QR code 04 is trained. In addition to the error correction, this gives the particular advantage that this matrix code 04 can be decoded and used with easily accessible and widely used means.

There are different types of barcodes. For example, barcodes always form an array of characters. It can be one-dimensional barcodes (1-D codes), two-dimensional barcodes 04 (2-D codes) and three-dimensional barcodes 04 (3-D codes). Normally, barcodes are essentially flat, so they essentially extend in only two spatial directions. An extension in a third spatial direction is harmless, provided the barcode 04 remains readable from corresponding directions. One-dimensional barcodes or barcodes have a series of different widths of bars, each usually colored in one of two colors, in particular either black or white. These bars are sequentially arranged along a linear direction or main orientation. Two-dimensional barcodes 04 , in particular matrix codes 04 , have characters arranged in multiple rows and in multiple columns. The rows and columns are preferably orthogonal to each other, but other angles are possible, such as the so-called MaxiCode 04. Thus, the characters form a matrix or are arranged like a matrix. The characters are usually each colored in one of two colors, in particular either black or white. Under a three-dimensional barcode 04 is in particular a barcode 04 to understand that in the Essentially like a two-dimensional barcode 04 is constructed, but the characters have a total of more than two different colors, the different colors convey a further meaning content. Variants of the three-dimensional barcode 04 are based, for example, on differences in hue, color saturation or color brightness. A two-dimensional or three-dimensional barcode 04, in particular a matrix code 04 requires less space with the same information content than a one-dimensional barcode. Both two-dimensional and three-dimensional barcodes 04 are also called matrix codes 04 designated.

barcodes 04 are usually standardized in their graphic representation as well as in their information content, z. In ISO / IEC 15415 (2-D) codes, ISO / IEC 15416 (1-D) codes, ISO / IEC 15418 (Data structures) or ISO / IEC 15420 , Known 1-D codes are z. B. the alphanumeric Code39 after ISO / IEC 16388 , the code128 after ISO / IEC 15417 or the purely numerical code Interleaved 2/5 after ISO / IEC 16390 , In two-dimensional barcodes 04 the information contained is also encrypted perpendicular to the respective main orientation. Examples of two-dimensional barcodes are matrix codes 04 like QR codes 04 , DataMatrix codes 04, MaxiCodes 04 or Aztec codes 04 , The QR code 04 is especially after ISO / IEC 18004 Are defined. The DataMatrix code 04 is in particular after ISO / IEC 16022 Are defined. The Aztec code 04 is especially after ISO / IEC 24778 Are defined. barcodes 04 and in particular matrix codes 04 For example, with a camera system, in particular a CCD camera, omnidirectional readable. Preferably, data is encoded using at least one error correction function. This can vary depending on the code 04 and, depending on the error correction function, more or less large parts of the illustrated matrix code 04 be flawed without affecting its readability.

The QR code 04 consists of a square matrix of symbols that represent the encoded data in binary form. In one form, the symbols are respective squares colored, for example, black or white. But it is also possible to use other symbols, provided their distinctness is guaranteed. In particular, alternative symbols such as circles can also be displayed in front of a background of a first color. So can a QR code 04 or another matrix code 04 are represented as a surface of a first color, which is interspersed by arranged on a raster symbols, in particular circles, a second color. The presence or absence of such a symbol, in particular a circle, at a grid location then represents the particular binary information. For a three-dimensional matrix code 04 the symbols can be colored differently. A special marker in three of the four corners of the square indicates the orientation. This marking is represented by a standardized arrangement of corresponding symbols, in particular circles. With the QR code 04 but also with other matrix codes 04, it is only necessary to ascertain the significance of each square structural element or other shaped symbol shown in the drawing plane, for example whether it is black or white or whether it is present or not.

To capture a matrix code 04 a camera system is preferably used, which detects the information two-dimensionally and evaluates the captured image, for example by means of a pattern recognition. The camera system therefore sets the detected structural elements of the matrix code 04 in an electronic, preferably digital payload.

The identification body is preferred 03 by means of a compact 06 temporarily against the object 02 pressed, in particular around the identification body 03 permanently with the object 02 connect to. Further preferred is the identification body 03 thereby by means of at least one adhesion promoter 07 permanently with the object 02 connected. The at least one adhesion agent 07 is for example at least one adhesive 07 , The at least one adhesion agent 07 For example, it is previously applied to the object 02 applied. Preferably, the at least one adhesion promoter 07 however, part of the identification body 03 and / or already with the identification body 03 connected before the identification body 03 and / or the at least one adhesion promoter 07 with the object 02 in contact. The identification body is preferred 03 with a pressure against the object 02 which is at least 2 Newton per square centimeter, more preferably at least 5 Newton per square centimeter, and even more preferably at least 10 Newton per square centimeter. The identification body is preferred 03 regardless of the lower pressure limit with a pressure against the object 02 which is at most 100 Newton per square centimeter, more preferably at most 50 Newton per square centimeter, and even more preferably at most 20 Newton per square centimeter.

At least one contact surface is preferred 08 of the compact 06 before and / or during the pressing of the identification body 03 against the object 02 heated, in particular by controlled and / or regulated energy supply. This is preferably at least one contact surface 08 heated to a temperature of at least 75 ° C, more preferably at least 100 ° C and even more preferably at least 125 ° C. This is preferred at least one contact surface 08 independently of the lower temperature limit, to a temperature of at most 200 ° C, more preferably at most 175 ° C, and even more preferably at most 150 ° C. Due to the heat, the adhesion promoter is preferred 07 changed, for example melted. In particular, in conjunction with the applied pressure thereby a particularly stable connection between the object 02 and identification body 03 generated. After cooling the identification body 03 this connection remains.

At least one carrier body preferably comes 09 used, a plurality of identification bodies 03 is formed supporting. Then many objects can be very fast and precise 02 successively with respective identification bodies 03 be provided. The carrier body 09 is in particular a carrier body 09 with a plurality of identification bodies 03 for marking at least one object 02 , The respective identification bodies 03 are preferably each in particular individually about at least one particular own layer of an adhesive 17 with the carrier body 09 connected. The adhesive remedy 17 preferably has a melting point which is relatively low, in particular lower than a melting point of the at least one adhesion promoter 07 , As an adhesive remedy 17 For example, there is a wax 17 for use. Is then through the heated contact surface 08 of the compact 06 Energy on the identification body 03 transferred, for example, melts the adhesive 17 , especially the wax 17 , The by the bonding agent 07 produced compound is much stronger than that by the adhesive 17 generated, even if the adhesive remedy 17 , especially wax 17 froze again. After transfer of the identification body 03 on the object 02 can the adhesive remedy 17 are neglected, in particular because its adhesion is so low that it then plays no role and / or because its optical properties are irrelevant and / or because it was at least partially removed during heating and pressing.

For example, the carrier body 09 as a band 09 , especially plastic band 09 or paper tape 09 formed on which the plurality of identification bodies 03 is arranged. The ribbon 09 has for example a thickness, ie a smallest dimension, which is preferably between 10 .mu.m and 100 .mu.m, more preferably between 20 .mu.m and 70 .mu.m and even more preferably between 30 .mu.m and 55 .mu.m. Such a carrier body 09 is arranged, for example, rolled up as a supply roll and is unwound by intermittent movement and preferably wound onto a waste roll, in particular after a transfer of respective identification bodies 03 , Along a transport path of the carrier body 09 After the supply roll and preferably in front of the waste roll, a marking point is preferably arranged on which the contact surface 08 of the compact 06 at least for transmitting the respective identification body 03 against a back of the carrier body 09 is pressed. In this case, the respective front side of the carrier body arranged on a side opposite the rear side of the carrier body 09 is preferred 09 arranged identification body 03 against the object to be marked 02 pressed and connected to this. The carrier body 09 is then preferably transported on, in particular until again an identification body 03 opposite the contact surface 08 is arranged and again a particular other object 02 with a signature body 03 can be provided.

Each identification body 03 preferably has at least one as a contrast layer 11 trained shift 11 on. This contrast layer 11 preferably has different optical properties than at least one with the contrast layer 11 cooperating layer 13 ; 14 , This makes it possible, from the interaction of the contrast layer 11 with this with the contrast layer 11 cooperating layer 13 ; 14 a label 01 to generate and represent. As with the contrast layer 11 cooperating layer 13 ; 14 comes, for example, a surface 13 of the object 02 itself or one as a cover layer 14 trained shift 14 of the identification body 03 for use.

For example, one with openings 12 provided contrast layer 11 arranged in the foreground and the visually different object 02 even in the background, that's how the object works 02 even as with the contrast layer 11 cooperating layer 13 and it will be the openings 12 the contrast layer 11 clearly visible and can be used to display information, for example in the form of a matrix code 04 , It is assumed that an adhesive layer 07 is not visible or even corresponding openings 12 having. The contrast layer 11 itself carries in this case the actual information in the form of openings 12 and is therefore an information carrier layer in this case 11 , Such a structure is in particular with identification bodies 03 for an upstream structuring, but in principle also with identification bodies 03 possible for downstream structuring. An upstream structuring is to be understood as a case in which the identification body 03 is first provided with a marking structure and then in particular by means of the compact 06 with the object 02 is connected. A downstream structuring is to be understood as a case in which the identification body 03 initially, in particular by means of the compact 06 with the object 02 and then provided with an identification structure.

On the other hand, one with openings 16 provided cover layer 14 arranged in the foreground and a visually different and from the object 02 different contrast layer 11 in the background, so are the openings 16 the topcoat 14 clearly visible and can be used to display information, for example in the form of a matrix code 04 , In this case is wearing the topcoat 14 the actual information in the form of the openings 16 and is therefore an information carrier layer in this case 11 , Such a structure is in particular with identification bodies 03 possible for downstream structuring. The corresponding at least one identification body 03 and / or the corresponding carrier body 09 is then characterized by the fact that the at least one cover layer 14 and the at least one contrast layer 11 differ in their optical properties. Preference is given to a color of the cover layer 14 essentially the color of the object 02 in the immediate vicinity of the identification body 03 , Thus, the identification body 03 as inconspicuous as possible.

Especially in the case of identification bodies 03 for an upstream structuring has the respective identification body 03 preferably at least the contrast layer 11 on. The contrast layer 11 stands in the case of identification bodies 03 for an upstream structuring on a contact side said first side preferably with the adhesion promoter 07 in contact and / or stands in the case of identification bodies 03 for an upstream structuring on a top side called second side, for example, directly to the carrier body 09 in contact and / or preferably directly with the adhesive 17 and thereby about the adhesive 17 indirectly with the carrier body 09 in contact. The adhesive remedy 17 itself is in this case preferably directly with the carrier body 09 in contact. (Exemplary is a carrier body 09 with identification bodies 03 for an upstream structuring in 2a shown.)

Preferably, at least in the case of identification bodies 03 for an upstream structuring of each identification body 03 at least one contrast layer 11 and at least one adhesive layer 07 on. This at least one adhesive layer 07 is the layer 07 that made up the at least one bonding agent 07 is formed. In particular, at least in the case of identification bodies 03 for an upstream structuring, the at least one contrast layer is preferred 11 about the at least one layer 17 the adhesive 17 with the carrier body 09 connected. marking bodies 03 for an upstream structuring therefore have one as an information layer 11 trained contrast layer 11, in particular by means of laser radiation prior to contact with the object 02 is provided with an identification structure, this information structure in particular in contrast with a surface of the object 02 becomes visible. For example, the object is essentially black. This is usually the case with vehicle tires. An example white contrast layer 11 a tag body 03 for an upstream structuring is then preferred with openings 12 provided so that after connecting the identification body 03 with the object 03 a particular white field with black symbols in the form of the openings 12 you can see. The openings 12 For example, as viewed from above, they have a substantially circular shape. Alternatively, colors other than white are used. Relevant is the contrast to the color of the object 02 at the appropriate place.

Especially in the case of identification bodies 03 for a downstream structuring, the respective identification body 03 prefers the at least one contrast layer 11 and additionally a cover layer 14 on. The at least one contrast layer 11 stands in the case of identification bodies 03 for a downstream structuring on a contact side said first side preferably with the adhesion promoter 07 in contact and / or stands in the case of identification bodies 03 for a downstream structuring on its upper side said second side, for example, directly with the cover layer 14 in contact. The cover layer 14 is thus on its underside preferably with the at least one contrast layer 11 in contact and / or stands on its upper side, for example, directly to the carrier body 09 in contact and / or preferably directly with the adhesive 17 and thereby indirectly via the adhesive 17 with the carrier body 09 in contact. The adhesive remedy 17 itself is in this case preferably directly with the carrier body 09 in contact. (Exemplary is a carrier body 09 with identification bodies 03 for downstream structuring in 3a shown.)

As the at least one contrast layer 11 is in a multi-colored version of identification bodies 03 for a subsequent structuring a sequence of at least two contrast layers 11 arranged, each having different optical properties, for example, different colors. These may then preferably be selectively exposed to together with the cover layer 14 a label 01 with selectable optical properties. This can be, for example, a multi-colored marking 01 his or a monochrome marking 01 their color by exposing the corresponding contrast layer 11 is selectable without other identification body 03 to use and / or without another carrier body 09 in the appropriate application device 18 to have to use. Regarding the order of the layers 07 ; 11 ; 14 Preferably, the above already applies to identification bodies 03 for a downstream structuring called with the addition that in place of at least one contrast layer 11 at least two contrast layers 11 to step. In the case of two contrast layers 11 would then be, for example, the carrier body 09 with the adhesive remedy 17 in direct contact and the adhesive 17 with the topcoat 14 in direct contact and the topcoat 14 with a first contrast layer 11 in direct contact and the first contrast layer 11 with a second contrast layer 11 in direct contact and the second contrast layer 11 with the adhesion agent 07 in direct contact. In between, further layers may optionally be arranged with further functions. labeling bodies 03 for downstream structuring, three or more contrast layers combined in a corresponding manner can also be used depending on requirements 11 exhibit.

Preferably, at least in the case of identification bodies 03 for a downstream structuring of each identification body 03 at least one cover layer 14 and at least one contrast layer 11 and at least one adhesive layer 07 on. This at least one adhesive layer 07 is the layer 07 that made up the at least one bonding agent 07 is formed. In particular, at least in the case of identification bodies 03 for a downstream structuring, the at least one contrast layer is preferred 11 between the adhesive layer 07 and the topcoat 14 arranged and preferably the cover layer over the at least one layer 17 of the adhesive 17 with the carrier body 09 connected. marking bodies 03 for a downstream structuring therefore have one as an information layer 11 trained cover layer 14 and an underlying underlying contrast layer 11 on, with the topcoat 14 in particular by means of laser radiation after the contact of the identification body 03 with the object 02 is provided with an identification structure and wherein this information structure in particular in contrast with the contrast layer 11 becomes visible.

For example, the object is essentially black. This is usually the case with vehicle tires. Then, for example, a tag body 03 for a downstream structuring with a likewise black cover layer 14 arranged. The contrast layer of the identification body 03 for a subsequent structuring is then white, for example. The particular black cover layer 14 of the identification body 03 for an upstream structuring is then after the connection of the identification body 03 with the object 03 preferably with openings 16 provided so that a black box with white symbols in the form of openings 16 to see, or more preferably only the white symbols in the form of openings 16 are visible because the top layer 14 visually with the object 02 merges. The openings 16 have, for example, a substantially circular shape when viewed from above. Alternatively, colors other than black and / or white are used. Relevant is the contrast to the color of the cover layer 14 to the color of the contrast layer 11 at the appropriate place. Preferably, the openings extend 16 in the case of identification bodies 03 for a subsequent structuring through the cover layer 14 and for safety's sake partly in the contrast layer 11 into it. This will ensure that the topcoat 14 completely open and the contrast layer 11 not completely open, but through the opening 16 the topcoat 14 is visible through.

Preferably, the at least one identification body 03 Irrespective of an upstream or a downstream structuring, at least in certain areas luminescent pigments and / or fluorescent paint and / or at least one fluorescent substance and / or at least one phosphorescent substance. This has the advantage that corresponding pigments or dyes or substances under normal lighting conditions with the naked eye are not or only very difficult to see, but can be made visible by appropriate lighting, such as UV light. As a result, markings can be generated that do not interfere with everyday life, but can be reliably identified if necessary.

For example, in the case of tag bodies 03 for an upstream structuring the at least one contrast layer 11 Luminescent pigments and / or phosphor ink and / or at least one fluorescent substance and / or at least one phosphorescent substance, more preferably the corresponding surface 13 of the object 02 not or at least in a different concentration. Then, after attaching the identification body 03 a label can be made recognizable, which consists for example of a fluorescent and / or phosphorescent surface with incorporated symbols.

For example, in the case of tag bodies 03 for a downstream structuring the at least one contrast layer 11 Luminescent pigments and / or phosphor ink and / or at least one fluorescent substance and / or at least one phosphorescent substance, more preferably the cover layer 14 not or at least in a different concentration. Then, after attaching the identification body 03 a label of fluorescent and / or phosphorescent symbols are exposed.

For example, in the case of tag bodies 03 for a subsequent structuring the top layer 14 Luminescent pigments and / or phosphor ink and / or at least one fluorescent substance and / or at least one phosphorescent substance, more preferably the at least one contrast layer 11 not or at least in a different concentration. Then, with the help of the fluorescent and / or phosphorescent properties of the identification body 03 safe on the object 02 be found and precisely treated further, for example, openings 16 in the topcoat 14 while ensuring that the identification body 03 is taken.

marking bodies 03 If appropriate, they may also be subject to both upstream and downstream structuring.

The identification body 03 preferably has a thickness, ie a smallest dimension which is at most 200 μm, more preferably at most 100 μm and even more preferably at most 50 μm. The thickness of the identification body 03 is preferably at least 1 .mu.m, more preferably at least 10 .mu.m and even more preferably at least 20 .mu.m.

In the method of applying a mark 01 on an object 02 is preferred, the identification body 03 before and / or after the pressing of the identification body 03 to the object 02 partially changed by entry of energy by means of at least one laser beam and thereby provided with an identification structure. Happens this material change before joining the identification body 03 with the object, this is also called upstream structuring. Happens this material change after connecting the identification body 03 with the object, this is also called downstream structuring. The material change consists for example of the removal, in particular burning and / or evaporation of parts of the identification body 03, in particular openings 11 the contrast layer 11 and / or openings 16 the topcoat 14 to create. It is therefore preferably avoided that the laser beam is the object 02 could affect yourself. Preferably, the method is characterized by the fact that the object 02 even by the entry of energy by means of the at least one laser beam remains materially unchanged. This is made possible by different embodiments of the method, which can also be combined with one another.

In a first embodiment of the method, which is also called embodiment with upstream structuring, the identification body 03 before pressing the identification body 03 to the object 02 partially changed by entry of energy by means of at least one laser beam and thereby provided with an identification structure. As a result, the identification structure can be produced without using the laser beam object 02 to impair. In a second embodiment of the method, which is also called an embodiment with downstream structuring, the identification body becomes 03 after pressing the identification body 03 to the object 02 partially changed by entry of energy by means of at least one laser beam and thereby provided with an identification structure. By not completely passing the laser beam through the tag body 03 penetrates, the identification structure can be made without using the laser beam object 02 to impair.

The at least one laser beam is preferably formed by electromagnetic radiation having a wavelength in the infrared range. In particular, the wavelength of the electromagnetic radiation of the laser beam is preferably at least 5 μm (five microns), more preferably at least 9 μm (nine microns), and / or independently at most 50 μm (fifty microns), more preferably at most 11 μm (eleven microns). For example, at least one carbon dioxide laser comes 19 as a laser source 19 for use. For example, the laser source 19 a laser power that is at least 5 W and / or that is at most 100 W. The generated laser beam is preferably deflected by means of in particular two movable, in particular pivotable mirrors and can thus be directed to different destinations. In this way, at different points of the respective identification body 03 a corresponding material change of the identification body 03 performed. The laser beam is preferably deactivated during the pivoting operations of the mirror. Thus, the material change is preferably made only in those places where a symbol of the label to be generated 01 is provided.

The method is preferably characterized in that the identification structure is formed by at least one layer 07 ; 11 ; 14 of the identification body 03 is removed in at least a limited area of space and thereby at least one through opening 12 ; 16 this at least one layer 07 ; 11 ; 14 is produced. Further preferred is a plurality of such openings 12 ; 16 generated. In the embodiment of the method with upstream structuring, the identification structure is preferably formed by at least the at least one contrast layer 11 and more preferably also the adhesive layer 07 of the identification body 03 is removed in at least a limited area of space and thereby at least one through opening 12 this at least one contrast layer 11 and preferably also this adhesive layer 07 is produced. In the embodiment of the method with downstream structuring, the identification structure is preferably formed in that at least the cover layer 14 of the identification body 03 is removed in at least a limited area of space and thereby at least one through opening 16 this topcoat 14 is generated and these openings 16 further preferably into at least one contrast layer 11 extend without completely penetrating them.

Preferably, the identification structure results from at least one of a plurality of through holes 12 ; 16 having layer 07 ; 11 ; 14 of the identification body 03 , This layer 07 ; 11 ; 14 preferably has an optical contrast to an underlying layer 11 ; 13 on. The layer below 13 is for example a surface 13 of the object 02 , in particular tire 02 itself, wherein then more preferably the embodiment of the method with upstream structuring is used. The layer below 11 is alternatively another layer 11 of the identification body 03 , in particular a contrast layer 11 of the identification body 03 , wherein then more preferably the embodiment of the method with downstream structuring is used.

In the embodiment of the method with upstream structuring, a structuring process is preferably carried out first. The method is characterized in particular in this case preferably by the fact that the identification body 03 before pressing the identification body 03 to the object 02 and more preferably before each contact with the object 02 is provided with the identification structure. (A result is exemplary and schematic in 2 B shown). For this structuring process, the identification body is preferred 03 positioned at a location accessible by the laser beam. This happens, for example, by an application device 18 is aligned accordingly. The application device 18 preferably has a supply of identification bodies 03 on. For example, this stock is on the tape 09 trained carrier body 09 arranged and rolled up on a supply roll. The application device 18 and the laser source 19 is aligned so relative to each other that one of the carrier body 09 opposite side of the identification body 03 the laser source 19 is facing. For example, the corresponding carrier body 09 at this moment already at the identification point of the application device 18 arranged. Then the irradiation of the identification body takes place 03 by means of the laser beam. In this case, the at least one contrast layer 11 with openings 12 provided in the form of the desired identification structure. This happens from the side of the identification body 03 off, later closer to the object 02 will be arranged. The identification structure is therefore preferably generated in mirror image, ie reversed. If preferred as already an adhesive layer 07 on the identification body 03 is arranged, this is in the area of the openings 12 preferably also removed.

Thereafter, in the embodiment of the method with upstream structuring, an alignment process is preferably carried out, followed by a contacting process and simultaneously with this contacting process and / or thereafter a joining process. In the alignment process, the identification body is preferred 03 relative to the object 02 aligned. In the contacting process, the identification body 03 with the object is preferred 02 brought into contact. The contacting process and the joining process together preferably last between 0.5 s and 4 s, more preferably at most 1 s. In the connection process, the identification body is preferred 03 connected to the object, in particular permanently. In the alignment process, the alignment is preferably done by the application device 18 is moved accordingly. Alternatively or additionally, the object itself is preferably moved. The movement of the application device 18 In particular, in this embodiment of the method has the advantage that optionally the laser source 19 does not need to be moved to the object 02 to provide enough space. The contact between identification body 03 on the one hand and object on the other hand, for example, produced by the fact that the entire application device 18 on the object 02 to be moved. However, it is preferred to produce this contact of the compacts 06 on the object 02 to move while the carrier body 09 with the identification body arranged thereon 03 between the compact 06 and the object is arranged. This is the compact 06 with the carrier body 09 in contact and comes the identification body 03 with the object 02 in contact. Preferably, this contacting process goes into the joining process by increasing the pressure with which the compact 06 the identification body 03 against the object 02 pressed. As described, the contact surface 08 of the compact 06 heated, for example by a heating element, the entire compact 06 heated. (Example is in 2c schematically a between pressed body 06 and object 02 arranged carrier body 09 with already structured identification body 03 shown.)

In a preferably subsequent removal process, the compact is preferred 06 again from the object 02 away. As a result, the identification body loses 03 prefers its contact with the carrier body 09 and stays on the object 02 , At least now, but preferably before and in particular by switching off a heating current, a cooling of the identification body takes place 03 , This also cools the bonding agent 07 and creates a lasting connection.

The object 02 is now with the label 01 provided and can be removed to the next object 02 To make room. This can in particular be provided with a different identification structure when the laser source 19 is controlled accordingly. (Example is in 2d schematically such an object 02 with identification body 03 shown.)

In the embodiment of the method with downstream structuring, the identification body is preferred first 03 on the object 02 appropriate. For this purpose, preferably an alignment process and then a contacting process and simultaneously with this contacting process and / or thereafter a connection process and then a removal process. (Example is in 3b schematically a between compact 06 and object 02 arranged carrier body 09 with not yet structured identification body 03 Unless contradictions arise, the same applies to the alignment process and / or the contacting process and / or the joining process and / or the removal process as already described for the embodiment of the method with upstream structuring. (Example is in 3c and 3e each schematically such an object 02 shown with not yet structured identification body 03. It shows 3e an embodiment in which the cover layer 14 has an enlarged dimension around the at least one contrast layer 11 However, in the embodiment of the method with downstream structuring, a structuring process takes place after the removal process. The application device 18 also in this case preferably has a supply of identification bodies 03 on. For example, this stock is on the tape 09 trained carrier body 09 arranged and rolled up on a supply roll.

In the embodiment of the method with downstream structuring, the method is preferably characterized in that the identification body 03 after pressing the identification body 03 to the object 02 is provided with the identification structure and further preferably characterized in that by generating the identification structure at least one layer 11 of the identification body 03 becomes visible, which was previously obscured. In the embodiment of the method with downstream structuring, the object is preferred for this structuring process 02 and thus also the marking body 03 arranged thereon positioned at a location which can be reached by the laser beam. This happens, for example, by the object 02 and / or the laser source 19 is aligned accordingly. The object 02 and the laser source 19 are aligned relative to each other so that one from the object 02 opposite side of the identification body 03 the laser source 19 is facing. Then the irradiation of the identification body takes place 03 by means of the laser beam. In this case, the cover layer is preferred 14 with openings 16 provided in the form of the desired identification structure. This happens from the side of the identification body 03 off, farther from the object 02 is arranged remotely. The identification structure is therefore preferably generated in the correct page. The openings are preferred 16 produced so deeply that they reach into the at least one contrast layer 11 rich, but not through them.

The object 02 is now with the label 01 provided and can be removed to the next object 02 To make room. This can in particular be provided with a different identification structure when the laser source 19 is controlled accordingly.

In a combined embodiment of the method, the identification body 03 has at least one contrast layer 11 and at least one cover layer 14 on. Then, first analogous to the embodiment of the method with upstream structuring, a first set of openings 12 in the form of a reversed structure generated by both the at least one contrast layer 11 as well as through the top layer 14 pass. Thereafter, the attachment of the identification body 03 on the object 02 as described. After that, there will be more openings 16 through the cover layer 14 through, but only partially into the contrast layer 11 generated as described in the embodiment of the method with downstream structuring. As a result, viewed from the outside through some of the openings 16 the contrast layer 11 and through some of the openings 12 the object 02 be seen without the object 02 could be affected by the laser beam.

Preferably, the method is characterized alternatively or additionally by the fact that the identification structure by a spatially limited change of optical properties of at least one layer 11 ; 14 of the identification body 03 is produced. In place of removing material of the tag body 03 can also be a change in color by means of a laser, if this on a layer 11 ; 14 is directed, whose color is variable by heat and / or by light of the wavelength of the laser.

The width is preferably at least 1 mm, more preferably at least 2 mm, and even more preferably at least 5 mm. The width is, for example, at most 100 mm, more preferably at most 50 mm, even more preferably at most 20 mm, and even more preferably still more preferably at most 10 mm.

For example, the matrix code 04 in each line between 5 and 200 provided grid locations for symbols, regardless of whether a symbol is actually arranged at a respective grid location or not. For example, the matrix code in each column has between 5 and 200 grid locations for symbols, regardless of whether a symbol is actually located at a respective grid location or not.

Different big openings 12 ; 16 can be, for example, by different laser powers and / or different optics of the laser source 19 realize. Symbols of a matrix code 04 can also each consist of several closely adjacent openings 12 ; 16 be assembled to achieve appropriate sizes.

By way of example, it is possible to use a 30 W laser source 19 a structuring of a label 01 in the form of a square matrix code with a side length of approx. 15 mm and with 30 x 30 screen spaces within less than 0.5 s.
