LABEL, LABEL TAPE AND METHOD FOR MAKING LABELS

Description

[0001] Labels are used for a variety of applications. For example, labels are used to mark objects to facilitate identification, classification, and / or sorting of the marked items.

[0002] To facilitate the attachment of labels to various objects, labels are often provided with an adhesive. This allows such self-adhesive labels to be attached to objects, eliminating the need for additional fasteners.

[0003] However, the use of adhesive in such self-adhesive labels has some disadvantages with regard to the production and / or application of the labels.

[0004] For example, the adhesive used can contaminate and / or damage machines and / or tools used in the production and / or processing of the self-adhesive labels. This can occur, for example, if parts of the label are cut or punched after the adhesive has already been applied to the label. The adhesive can contaminate and / or damage the cutting or punching tool used during the cutting or punching process. Other tools and / or machines used to process and / or handle the labels, particularly after the cutting or punching process, can also be contaminated and / or damaged by the adhesive.

[0005] Furthermore, the adhesive can also cause disadvantages when using the labels in their intended application, for example, for marking objects. For example, the adhesive can extend beyond an edge of the label and / or the adhesive can collect at an edge of the label, which can contaminate and / or otherwise affect the user's hands and / or the object to which the label is attached and / or other objects.

[0006] From the state of the art, no or only inadequate measures are known to counteract such disadvantages of self-adhesive labels provided with adhesive.

[0007] US Pat. No. 5,351,426 A discloses a label assembly that improves the removability of individual labels from a carrier sheet. The labels are distributed longitudinally along the entire length of the carrier sheet. An adhesive temporarily holds the labels to the carrier sheet. A transverse leading edge of each label is adhesive-free.

[0008] GB 2 288 162 A discloses a self-adhesive postage stamp comprising: a layer of stamp paper with a printed stamp design on the front and perforated edges, a layer of pressure-sensitive adhesive on the back of the stamp paper, and a removable backing sheet covering the adhesive. Preferably, the pressure-sensitive adhesive is a hot-melt adhesive, and preferably the adhesive is applied by screen printing. A layer of moistenable, water-soluble adhesive may be disposed between the stamp paper and the pressure-sensitive adhesive layer. Preferably, the adhesive layer does not extend to the perforated edges of the stamp, but leaves a free edge.Such stamps are manufactured by a process comprising the following steps: providing a sheet or web of stamp paper having perforation lines defining stamps therein, followed by coating the back of the stamp paper with a layer of pressure-sensitive adhesive and a removable backing sheet.

[0009] Furthermore, DE 195 01 380 A1 discloses a label and a method for producing the label with reduced pressure-sensitive adhesive bleeding. A composite consisting of a carrier tape and a self-adhesive first film web is punched into smaller bottom film sections using a first punch. A second punch is used to punch another film web into smaller top film sections, which are larger than the bottom film sections. The top film sections are placed over the bottom film sections. As a result, the top film sections are larger on all sides than the bottom film sections.

[0010] However, in the process described, the composite of the carrier tape and the self-adhesive first film web is punched, which means that during punching, and possibly also during further processing of the labels, the tools and / or machines used can be contaminated and / or damaged by contact with the adhesive.

[0011] It is an object of the present invention to provide a self-adhesive label or a method for producing self-adhesive labels in order to overcome the disadvantages of the prior art and in particular to facilitate the handling of self-adhesive labels.

[0012] This object is achieved by the subject matter of the independent patent claims. Advantageous embodiments with expedient further developments of the invention are specified in the respective subclaims and in the following description.

[0013] A first aspect of the invention relates to a method for producing labels. The method comprises step a), in which a base material web is provided.

[0014] The base material web can be provided in the form of a tape, which is preferably wound on at least one roll and unwound from the roll when the base material web is provided. In the unwound state, the base material web can have a length in a longitudinal direction of the base material web of at least 10 m, preferably at least 20 m, more preferably at least 50 m, more preferably at least 100 m. Furthermore, the base material web can be an endless web.

[0015] The base material web is preferably flexible and / or pliable to facilitate its processing and / or transport, for example in the form of a wound roll.

[0016] The base material web can be a silicone-containing or siliconized paper. The base material web can be a multilayer composite. For example, such a multilayer composite can have at least one silicone layer. Alternatively, the base material web can be a plastic film, preferably a film made of polyester and / or at least one polyolefin. A film made of polypropylene (PP), polyethylene (PE), and / or polyvinyl chloride (PVC) is also conceivable. The base material web can comprise synthetic and / or natural materials.

[0017] Preferably, the base material web has a thickness of 50 µm to 200 µm, preferably 50 µm to 70 µm, more preferably 75 µm to 150 µm, more preferably 100 µm to 150 µm.

[0018] The material of the base material web can have a relatively high stiffness, or at least a higher stiffness than one or more of the other components of the manufactured label, in order to improve the handling and / or robustness of the label, for example, through a sufficiently high residual stress and / or restoring force of the base material web. This can additionally or alternatively improve the peeling behavior of the label, for example, the peeling behavior of the base material web from another component of the label and / or the peeling behavior of another component of the label from the base material web.

[0019] The base material web can be transported and provided by means of at least one transport device. The transport device can have at least one drive device that can drive the transport device and thus move the base material web. For this purpose, the transport device can have a drive roller that is configured to interact with the base material web and drive it in a moving manner. The drive roller can be driven by the drive device of the transport device.

[0020] In addition, the base material web can be guided over one or more deflection rollers and / or guide rollers and / or made available to the manufacturing process.

[0021] The method further comprises step b), in which at least one adhesive is applied to the base material web along at least one row by means of at least one application device. The adhesive is applied intermittently to the base material web along the row, so that the row has a plurality of individual adhesive regions, each spaced apart from one another by adhesive-free regions. The adhesive is a hot-melt adhesive.

[0022] The adhesive can be applied to the base material web, for example, using a hot-melt application head as the application device. Alternatively, the application device can be a printing device, such as a screen printing device, that prints the adhesive onto the base material web. It is also conceivable to use multiple application devices, such as multiple hot-melt application heads and / or printing devices, which apply adhesive to the base material web either at least partially simultaneously or at least partially sequentially.

[0023] The application device may have at least one opening from which the adhesive can be dispensed and applied to the base material web. Preferably, the application device has a plurality of openings, which may be arranged in a matrix, for example, in one row or in several rows.

[0024] A variety of different adhesive types can be used for application to the base material web. Furthermore, the adhesive can be applied to the base material web in different layer thicknesses. The adhesive types and / or the layer thickness of the respective adhesive to be applied can be selected and / or adapted to the adhesive strength requirements and / or the properties of the object to which the label is to be adhered and / or the stresses on the connection between the label and the object to which the label is to be adhered. For example, in applications for objects with low adhesive properties, such as steel or rolled products made of steel, concrete, wood or some plastics, an adhesive with a stronger adhesive strength can be selected and / or applied to the base material web in a thicker layer thickness.The adhesive is applied to the base material web in a layer thickness of 40 to 200 µm. The application device can be configured to vary the adhesive layer thickness.

[0025] The adhesive can be stored in at least one adhesive reservoir. When needed, i.e., during application and / or before application of the adhesive to the base material web, the adhesive can be fed from the adhesive reservoir to the application device.

[0026] The application device can apply the adhesive row by row, i.e. along at least one row, to the base material web. The adhesive can be applied to the base material web along each row at preferably predefined time intervals, i.e. discontinuously or intermittently, along the row. This allows a plurality of individual adhesive regions, each spaced from one another by adhesive-free regions, to be applied row by row to the base material web. The application device and the base material web can move relative to one another when the adhesive is being applied to the base material web. For this purpose, the application device can be transported, for example by means of at least one, preferably controlled, movement device, and / or the base material web can be transported, for example by means of at least one, preferably controlled, base material web transport device.

[0027] The adhesive regions can each have a substantially uniform shape and / or substantially uniform dimensions. The adhesive regions can have any desired shapes and / or contours. The shape and / or contour of the adhesive regions can depend, among other things, on the manner in which the adhesive is applied and / or the type of application device. Preferably, the adhesive regions each have a substantially rectangular shape, with respect to a viewing direction perpendicular to the surface of the base material web to which the adhesive regions are attached. However, other shapes and / or contours are also conceivable.

[0028] The method further comprises step c), after which a covering material is provided. The covering material can be provided in the form of a strip, which is preferably wound on a roll and unwound from the roll when the covering material is provided. In the unwound state, the covering material in the form of a strip can have a length in a longitudinal direction of the covering material strip of at least 10 m, preferably at least 20 m, more preferably at least 50 m, more preferably at least 100 m. Furthermore, the covering material can be in the form of a web, preferably an endless web.

[0029] The cover material is preferably flexible and / or pliable to facilitate its processing and / or transport, for example in the form of a wound roll.

[0030] The cover material can be a silicone-containing or siliconized paper. The cover material can be a multilayer composite. For example, such a multilayer composite can have at least one silicone layer. Alternatively, the cover material can be a plastic film, preferably a film made of polyester and / or at least one polyolefin. A film made of polypropylene (PP), polyethylene (PE), and / or polyvinyl chloride (PVC) is also conceivable. The cover material can comprise synthetic and / or natural materials.

[0031] Preferably, the cover material has a thickness of 50 µm to 200 µm, more preferably 75 µm to 150 µm, more preferably 100 µm to 150 µm.

[0032] The cover material can also have a relatively high rigidity, or at least a higher rigidity than one or more of the other components of the label, in order to improve the handling and / or robustness of the label, for example, through a sufficiently high residual stress and / or resilience of the cover material. This can also improve the peeling behavior of the label, for example, the peeling behavior of the cover material from another component of the label, for example, from the base material web, or the peeling behavior of another component of the label from the cover material.

[0033] The cover material can be transported and provided by means of at least one transport device. The transport device can have at least one drive device that can drive the transport device and thus move the cover material. For this purpose, the transport device can have a drive roller that is designed to interact with the cover material and drive it in a moving manner. The drive roller can be driven by the drive device of the transport device.

[0034] In addition, the cover material can be guided and provided via one or more deflection rollers and / or guide rollers.

[0035] The method further comprises step d), after which the cover material is applied at least in regions to the base material web, so that several of the applied adhesive regions are completely covered by the cover material.

[0036] The cover material and the base material web, with the adhesive areas adhering thereto, are preferably laminated together by means of at least one laminating device to form a composite which comprises at least the base material web, the adhesive and the cover material.

[0037] When applying the cover material at least partially to the base material web, the cover material can be moved along a cover material transport direction and the base material web can be moved along a base material web transport direction, wherein the cover material transport direction and the base material web transport direction can run parallel and / or coincident to one another. Alternatively, the cover material can remain stationary and the base material web can be moved, for example, by means of at least one base material web transport device, or the base material web can remain stationary and the cover material can be moved, for example, by means of at least one cover material transport device.

[0038] The cover material can be applied to the base material web from above, from below or from one side with respect to a vertical direction when the production line for producing the labels is in an operating position.

[0039] Because the cover material completely covers several or a large number, i.e. at least 2, of the applied adhesive regions, the cover material also extends over at least one adhesive-free region arranged between the adhesive regions covered by the cover material. The cover material can cover more than two adhesive regions, for example 3, 4, 5, 10, 15, 20 or more adhesive regions. The cover material can also at least partially cover adhesive-free regions that are not arranged along the row, i.e. not between two adjacent adhesive regions along the row. For example, the cover material can cover adhesive-free regions that are arranged laterally next to the row, for example between two rows if several rows are provided.

[0040] The method preferably also comprises step e), according to which the base material web and / or the cover material is at least partially separated exclusively along adhesive-free regions by means of at least one separating device.

[0041] Preferably, the base material web and / or the cover material is at least partially separated exclusively along adhesive-free regions at a distance of at least 0.25 mm, preferably at least 0.5 mm, more preferably at least 1 mm, more preferably at least 1.5 mm, more preferably at least 2 mm, more preferably at least 3 mm, more preferably at least 4 mm, more preferably at least 6 mm, more preferably at least 8 mm, more preferably at least 10 mm, from each adhesive region.

[0042] Preferably, the base material web and / or the cover material is at least partially separated exclusively along adhesive-free regions at least in regions at a distance of 0.25 mm to 5 mm, preferably from 0.5 mm to 4 mm, more preferably from 0.5 mm to 3 mm, more preferably from 0.5 mm to 2 mm, from a region of the adhesive regions.

[0043] Separation in the sense of the present invention can be a complete separation, ie a complete separation from each other of respective regions of the base material web and / or of respective regions of the cover material, or only a region-by-region and / or point-by-point separation, for example perforation.

[0044] Preferably, the base material web and the cover material are at least partially separated simultaneously or successively.

[0045] However, only the base material web or only the cover material can also be at least partially separated. For example, the separating device can only penetrate into a region of the composite that comprises at least the base material web and the cover material, thus at least partially separating only the base material web or only the cover material, without both the base material web and the cover material being at least partially separated.

[0046] The separating device can, for example, be a punching device which is designed to punch the base material web and / or the cover material in order to at least partially, preferably completely, separate respective regions of the base material web and / or respective regions of the cover material from one another.

[0047] The base material web and / or the cover material can be at least partially separated substantially transversely, in particular substantially transversely to the row or rows of adhesive regions, along adhesive-free regions. Alternatively or additionally, the base material web and / or the cover material can be at least partially separated longitudinally, ie, substantially parallel to the row or rows of adhesive regions, along adhesive-free regions.

[0048] By at least partially separating the base material web and / or the cover material exclusively along adhesive-free areas, the cutting contour of each individual label produced lies entirely in areas where no adhesive has been applied. This prevents or at least reduces contact of the adhesive with the separating device, thus preventing or at least reducing contamination and / or damage to the separating device, e.g., the cutting or punching tool.

[0049] Due to the adhesive-free separating edges of the base material web and / or the cover material thus created, contamination and / or damage to other tools and / or machines for processing and / or handling the labels, in particular after the separating step, can be avoided or at least reduced.

[0050] By separating exclusively along adhesive-free areas, unwanted flow and / or spreading and / or smearing of the adhesive, for example beyond an edge of the cover material and / or the base material web, can be avoided or at least reduced.

[0051] Due to the reduced contamination and / or damage to the corresponding tools and / or machines, downtime and / or maintenance and / or repair costs for cleaning and / or repairing the tools and / or machines can also be reduced.

[0052] Multilayer composite materials are frequently used for labels. For example, the base material web can be a multilayer composite, wherein the composite preferably comprises at least one silicone layer. When separating such composite materials using a separating device, for example a punching device, individual layers, for example the silicone layer, can be compromised or damaged, allowing adhesive to penetrate the multilayer composite. This can compromise the multilayer composite. For example, individual layers of the composite can become detached. This can cause damage to corresponding processing tools and / or processing machines, and downtimes for the same. These effects can be avoided or at least reduced by separating exclusively along adhesive-free areas.

[0053] Due to the adhesive-free separation edges of the label produced using the manufacturing process described above, and the reduced flow and / or smearing of the adhesive, the labels can be made easier to handle during use. For example, contamination and / or other adverse effects on objects and / or the user's body, particularly on the user's hands, caused by the adhesive can be avoided or at least reduced. This can increase the user-friendliness of the produced labels.

[0054] Furthermore, this can enable automatic and reliable label dispensing. In particular, it can prevent or at least reduce contamination and / or damage to a label dispenser that can dispense the produced labels for use. This can also reduce downtime and / or maintenance and / or repair costs for the label dispenser.

[0055] Overall, the handling of the self-adhesive labels produced by the method according to the invention can be improved or facilitated both in the production process and in the application, ie when applying them to objects.

[0056] Furthermore, by means of the described manufacturing method, in particular by means of the intermittent application of the adhesive to the base material web and the at least partial separation of the base material web and / or the cover material exclusively along adhesive-free areas, a relatively high manufacturing speed of self-adhesive labels can be realized with comparatively few and / or less complex manufacturing steps compared to the methods known from the prior art.

[0057] The separation of the base material web and / or the cover material by means of at least one separation device can be controlled at least partially automatically, for example with the aid of a provided control unit. For this purpose, at least one sensor, preferably an optical sensor, can additionally be provided. At least one marking can be provided on the cover material and / or on the base material web. The sensor can be configured to detect the marking, preferably optically, and to provide information about the position of the marking to the control unit. The control unit can control an alignment and / or a positioning of the separation device(s) relative to the cover material and / or the base material web, at least partially based on the provided information.The control device can control an alignment device and / or a positioning device in order to align and / or position the separating device(s) relative to the cover material and / or the base material web.

[0058] It can also be provided that the sensor and the control unit can control an alignment and / or positioning of the separating device(s) relative to the cover material and / or the base material web without such markings. Instead of a marking, the sensor can detect alternative features and provide information about them to the control unit in order to control an alignment and / or positioning of the separating device(s) relative to the cover material and / or the base material web. For example, the sensor can be configured to detect the alignment and / or positioning of the adhesive regions and provide information about them to the control unit. The control unit can be configured to control an alignment and / or positioning of the separating device(s) relative to the cover material and / or the base material web, at least partially based on the information provided.

[0059] Preferably, the base material web is transported at least in sections along a base material web transport direction by means of at least one transport device and / or the cover material is transported at least in sections along a cover material transport direction by means of at least one transport device.

[0060] The base material web and the cover material can be transported by a common transport device or several common transport devices. Alternatively, the base material web and the cover material can be transported by separate transport devices, preferably independently of one another. The transport device(s) can each have a drive roller, which interacts with and drives the base material web and the cover material. The transport device(s) can also have a plurality of rollers, at least one or more of which are driven.

[0061] In step b), the row along which the adhesive is intermittently applied to the base material web preferably runs along the base material web transport direction.

[0062] Preferably, the base material web transport direction and the cover material transport direction run at least in sections at an angle of 30° to 120°, preferably of 40° to 110°, more preferably of 50° to 100°, more preferably of 60° to 95°, more preferably of 70° to 95°, to each other.

[0063] Preferably, before step d), the base material web is deflected by means of at least one deflection device from a first base material web transport direction to a second base material web transport direction, so that the second base material web transport direction and the cover material transport direction run essentially parallel to one another or are coincident after the deflection. Additionally or alternatively, preferably before step d), the cover material is deflected by means of at least one deflection device from a first cover material transport direction to a second cover material transport direction, so that the second cover material transport direction and the base material web transport direction run essentially parallel to one another or are coincident after the deflection.

[0064] The provision of at least one deflection device, preferably a plurality of deflection devices, can enable a variable spatial arrangement and / or orientation of the machine(s) and / or processing stations and / or tools used for the production process. In other words, the machines and / or processing stations and / or tools used to produce the labels can be spatially arranged independently of the intended or assumed orientation and / or positioning of the base material web and / or the cover material at the respective processing stations for producing the labels, since the deflection device can effect the intended or assumed orientation and / or positioning of the base material web and / or the cover material by deflecting the same.This allows the machines and / or processing stations and / or tools used to produce the labels to be arranged in a more compact and / or space-efficient manner.

[0065] Preferably, at least before the application of the cover material in step d), the cover material transport direction runs, at least in some areas, essentially opposite to the base material web transport direction. This allows the base material web and the cover material to be fed from essentially opposite directions. This can enable flexible and / or independent guidance of the base material web and the cover material.

[0066] Alternatively or additionally, at least when applying the cover material in step d), the cover material transport direction and the base material web transport direction can be substantially in the same direction.

[0067] The cover material can be applied longitudinally along the row or rows of adhesive regions to the base material web. The cover material can have a smaller width transverse to the cover material transport direction and / or base material web transport direction than the base material web, particularly when multiple rows of adhesive regions are applied side by side to the base material web. Multiple cover material webs, particularly one cover material web per row of adhesive regions, can be applied side by side, preferably substantially parallel to one another, to the base material web. Alternatively, the cover material can be applied to the base material web transverse to the row or rows of adhesive regions and / or to the cover material transport direction and / or base material web transport direction.

[0068] Preferably, in step d), several cover material webs are applied to the base material web, so that several of the applied adhesive areas are completely covered by a respective cover material web. The cover material webs are preferably applied to the base material web running substantially parallel to one another.

[0069] Preferably, in step b), the adhesive is applied intermittently to the base material web along at least two, preferably at least three, more preferably at least four, rows extending substantially parallel to one another and spaced from one another by adhesive-free regions. Each row preferably has a plurality of individual adhesive regions, each spaced from one another by adhesive-free regions. The rows can be applied to the base material web side by side, with respect to a direction transverse to the rows and / or to the cover material transport direction and / or base material transport direction. The rows are preferably spaced from one another by adhesive-free regions.

[0070] In step b), the rows can be applied to the base material web essentially simultaneously, i.e., an adhesive region can be applied to the base material web essentially simultaneously for each intended row. Alternatively, the rows can be applied to the base material web one after the other, i.e., the adhesive regions for one row are applied intermittently to the base material web, and subsequently, i.e., with a time delay, the adhesive regions for another row are applied intermittently to the base material web.

[0071] Preferably, step e) comprises the following step(s): e1) the base material web and / or the cover material are separated at least partially, preferably completely, outside the adhesive regions, running parallel to the row; and / or e2) the base material web and / or the cover material are separated at least partially, preferably completely, outside the adhesive regions, running transversely to the row of adhesive regions.

[0072] The respective separation paths, i.e., running parallel to the row and / or transverse to the row of adhesive areas, can determine or at least influence the contour and / or dimensions and / or other properties, such as the number of adhesive areas per label, of the produced label. Furthermore, this allows individual labels to be separated from a label strip comprising a plurality of connected labels, which can be arranged, for example, in a matrix-like manner, preferably in several rows, in the label strip.

[0073] Steps e1) and e2) can be performed simultaneously or sequentially.

[0074] The base material web can be a release material, preferably a silicone paper, for removal from the respective adhesive area or areas of the produced label, and the cover material can be a plastic film, preferably a film made of polyester and / or at least one polyolefin. Alternatively, the base material web can be a plastic film, preferably a film made of polyester and / or at least one polyolefin, and the cover material can be a release material, preferably a silicone paper, for removal from the respective adhesive area or areas of the produced label.

[0075] When applying the finished label, the release liner can be removed from the adhesive area, leaving the adhesive area attached to the plastic film. The plastic film, with the adhesive in the adhesive area, can then be adhered to an object, for example, to mark the object.

[0076] Preferably, the plastic film, which can be designed as a base material web or as a cover material, has a thickness of 50 µm to 200 µm, more preferably 75 µm to 150 µm, more preferably 100 µm to 150 µm.

[0077] The material of the base material web can also have a relatively high stiffness, or at least a higher stiffness than one or more of the other components of the label, in order to improve the handling and / or robustness of the produced label, for example, through a sufficiently high residual stress and / or restoring force of the base material web. This can also improve the peeling behavior of the label, for example, the peeling behavior of the base material web from another component of the label or the peeling behavior of another component of the label from the base material web.

[0078] The adhesive may have a greater adhesive force on the base material web than on the cover material. Alternatively, the adhesive may have a greater adhesive force on the cover material than on the base material web. The adhesive force may be determined at least partially by the surface structure of the cover material and / or the base material web. Thus, the surface structure of the cover material and / or the base material web can be predefined and / or modified, for example, by a treatment process, to achieve a desired and / or required adhesive force on the cover material and / or the base material web. Alternatively or additionally, the adhesive force of the adhesive may be determined at least partially by its composition.

[0079] Preferably, before step d), the cover material can be divided into smaller cover material segments, preferably cover material strips, in such a way, preferably transversely to the row of adhesive regions and / or transversely to the cover material transport direction and / or transversely to the base material web transport direction, that the cover material segments have a width in a width direction which is from 1 mm to 15 mm, preferably from 2 mm to 10 mm, greater than a width of the respective adhesive regions in the same width direction after the cover material has been applied to the base material web.Alternatively or additionally, preferably before step d), the base material web can be divided into smaller base material web segments, preferably base material web strips, such that the base material web segments have a width in a width direction that is from 1 mm to 15 mm, preferably from 2 mm to 10 mm, greater than a width of the respective adhesive regions in the same width direction.

[0080] The provision of such cover material segments or base material web segments can increase the flexibility and / or variability in the production of the labels.

[0081] Preferably, the width direction may extend along the row of adhesive regions and / or along the base material web transport direction and / or along the cover material transport direction.

[0082] Preferably, the cover material segments can each have a longitudinal axis, wherein the cover material segments are preferably applied to the base material web and the adhesive regions in step d) such that the longitudinal axes of the cover material segments run transversely to the row of adhesive regions and / or transversely to the base material web transport direction and / or transversely to the cover material transport direction after the respective cover material segments have been applied to the respective adhesive regions. Alternatively or additionally, the base material web segments can each preferably have a longitudinal axis, which preferably runs along the row of adhesive regions and / or along the base material web transport direction and / or along the cover material transport direction.

[0083] Preferably, at least one marking element, preferably a plurality of marking elements, can be applied to the base material web and / or to the cover material at least before step e), wherein the separation of the base material web and / or the cover material in step e) can be controlled at least in part by means of the marking element(s).

[0084] The separation of the cover material and / or the base material web via the adhesive regions in step e) can be controlled at least partially automatically, at least partially with the aid of the marking element(s), for example by means of a provided control unit. For this purpose, at least one sensor, preferably an optical sensor, can additionally be provided. The sensor can be configured to detect the marking element(s), preferably optically, and to provide information about the position and / or orientation of the marking element(s) to the control unit. The control unit can control an alignment and / or positioning of the separating device(s) relative to the cover material and / or the base material web, at least partially based on the provided information.The control device can control an alignment device and / or a positioning device in order to align and / or position the separating device(s) relative to the cover material and / or the base material web and then to at least partially separate the cover material and / or the base material web.

[0085] Alternatively, the sensor and the control unit can also control an orientation and / or positioning of the separating device(s) relative to the cover material and / or the base material web without marking elements. Instead of a marking element, the sensor can detect alternative features and provide information about them to the control unit in order to control an orientation and / or positioning of the separating device(s) relative to the cover material and / or the base material web.

[0111] Further advantages, features, and details of the invention will become apparent from the following description of a preferred embodiment and from the drawings. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respective specified combinations, but also in other combinations or on their own, without departing from the scope of the invention.

[0112] Fig. 1 and 2show a base material web 10 with adhesive regions 12 applied thereto, each having an adhesive adhering to the base material web 10. The adhesive regions 12 are shown in dashed lines in the figures. The base material web 10 is preferably a continuous web. The base material web 10 preferably has a total length of at least 10 m, preferably at least 20 m, more preferably at least 50 m, more preferably at least 100 m.

[0113] The base material web 10 can be a silicone-containing or siliconized paper. The base material web 10 can be a multilayer composite. For example, the base material web 10 can be a multilayer composite with at least one silicone layer. Alternatively, the base material web 10 can be a plastic film, preferably a film made of polyester and / or at least one polyolefin. A film made of polypropylene (PP), polyethylene (PE), and / or polyvinyl chloride (PVC) is also conceivable. The base material web 10 can comprise synthetic and / or natural materials.

[0114] The adhesive on the adhesive areas 12 is applied in a manufacturing process according to the invention by means of at least one application device (not shown) onto the base material web 10 along two rows 14a, 14b, the course of which is in the Fig. 1 and 2each marked with an arrow. According to the manufacturing method according to the invention, the adhesive is applied intermittently along the rows 14a, 14b to the base material web 10, so that the rows 14a, 14b each have a plurality of individual adhesive regions 12, which are each spaced from one another by adhesive-free regions 16. More than two rows, for example at least three, four, or five rows each, of adhesive regions 12 can also be applied to the base material web 10.

[0115] The adhesive areas 12 are in Fig. 1 and 2 rectangular, with respect to a viewing direction perpendicular to the surface of the base material web 10 to which the adhesive regions 12 are attached. However, the adhesive regions 12 may also have alternative shapes and / or contours.

[0116] The rows 14a, 14b of adhesive regions 12 are arranged adjacent to one another and spaced apart from one another, i.e., the rows 14a, 14b of adhesive regions 12 are also spaced apart from one another transversely to the extension of the rows 14a, 14b by adhesive-free regions 18. The rows 14a, 14b can be applied to the base material web 10 essentially simultaneously, i.e., one adhesive region 12 can be applied to the base material web 10 essentially simultaneously for each provided row 14a, 14b. Alternatively, the rows 14a, 14b can be applied successively to the base material web 10, ie, the adhesive regions 12 for a first row 14a are applied intermittently to the base material web 10 and subsequently, ie, staggered in time, the adhesive regions 12 for a further row 14b are applied intermittently to the base material web 10.

[0117] In Fig. 2 is additionally compared to the Fig. 1A cover material 20 is arranged in regions on the base material web 10. The cover material 20 can, for example, be unwound and provided from one or more rolls and applied to the base material web 10 by means of a device, for example a laminating device.

[0118] The cover material 20 completely covers a plurality of the applied adhesive regions 12 and the adhesive-free regions 16 arranged between the adhesive regions 12. According to the embodiment of Fig. 2The cover material 20 is fed in several parts to the base material web 10 and applied thereto. The cover material 20 is in particular designed in strip or web form, with each strip or web of the cover material 20 completely covering a row 14a, 14b of adhesive regions 12. In other words, each strip or web of the cover material 20 completely covers each row 14a, 14b of adhesive regions 12.

[0119] However, it is also conceivable to supply the cover material 20 in one piece to the base material web 10 and apply it thereto. In this case, the cover material 20 would completely cover both rows 14a, 14b of adhesive areas 12, or several rows of adhesive areas 12, in one piece.

[0120] The adhesive areas 12 are arranged between the base material web 10 and the cover material 20. Thus, the adhesive areas 12 are located, from the perspective in Fig. 2, hidden beneath the cover material 20.

[0121] The composite comprising at least the base material web 10, the adhesive areas 12 and the cover material 20 forms a label strip 60, which can be further processed into individual labels.

[0122] The label strip 60 can preferably be wound onto and unwound from a roll before and / or after assembly or lamination of the label strip 60. This allows the label strip 60 to be transported, for example, to a recipient and / or to further processing stations.

[0123] In one step of the method according to the invention, the base material web 10 and the cover material 20, as a composite, are at least partially separated exclusively along adhesive-free regions 16, 18 by means of at least one separating device (not shown).

[0124] Exemplary separating lines 24a, 24b, along which the base material web 10 and the cover material 20 are at least partially separated, are shown in Fig. 2 marked with dot-dash lines.

[0125] The separating line 24a runs essentially transversely to the rows 14a, 14b of the adhesive regions 12. Thus, the separating line 24a runs, on the one hand, through the adhesive-free regions 16, which are arranged between the adhesive regions 12 of a respective row 14a, 14b, and, on the other hand, also through the adhesive-free region 18, which is arranged between the rows 14a, 14b. The separating line 24a thus corresponds to a cross-section of the label strip 60. Fig. 2For the sake of clarity, only one separating line 24a is shown between two adjacent adhesive areas 12 of the respective rows 14a, 14b. However, it is understood that along the entire respective row 14a, 14b, the base material web 10 and the cover material 20 can be separated in the adhesive-free areas 16, ie along respective separating lines 24a. Further separating lines 24a preferably run substantially parallel to the Fig. 2 shown dividing line 24a.

[0126] The separating line 24b runs essentially parallel to the rows 14a, 14b through the adhesive-free area 18, which is arranged between the rows 14a, 14b. The separating line 24b thus corresponds to a longitudinal section of the label strip 60. Although in Fig. 2only one separating line 24b is shown, further separating lines 24b can also be provided, along which the base material web 10 and the cover material 20 can be at least partially separated in the adhesive-free areas 18. Further separating lines 24b preferably run essentially parallel to the Fig. 2 shown dividing line 24b.

[0127] The cross-sectional cut, ie, along the dividing line 24a, of the label strip 60 can be performed using a transverse cutting device (not shown), and the longitudinal cut, ie, along the dividing line 24b, of the label strip 60 can be performed using a longitudinal cutting device. Alternatively, the cross-sectional cut and the longitudinal cut can be performed using a common cutting device.

[0128] However, alternative dividing lines are also conceivable, which differ from those in Fig. 2shown dividing lines 24a, 24b, provided that the dividing lines run exclusively along adhesive-free areas, for example the adhesive-free areas 16, 18.

[0129] The base material web 10 has a plurality of marking elements 21 in order to control the separation of the base material web 10 and the cover material 20 partly based on the marking elements 21, preferably at least partially automatically. For this purpose, a control unit (not shown) can be provided which is configured to control an alignment and / or positioning of at least one separating device relative to the cover material 20 and the base material web 10. In addition, at least one sensor, preferably an optical sensor, can be provided which is configured to detect the marking elements 21, preferably optically, and to provide information about the position of the marking elements 21 to the control unit. The control unit can be configured to control an alignment and / or positioning of the separating device relative to the cover material 20 and the base material web 10, at least partially based on the provided information.The control unit can control an alignment device and / or a positioning device in order to align and / or position the separating device relative to the cover material 20 and the base material web 10.

[0130] The sensor and the control unit can also control an alignment and / or positioning of the separating device relative to the cover material 20 and the base material web 10 without marking elements 21. Instead of the marking elements 21, the sensor can detect alternative features and provide information about them to the control unit in order to control an alignment and / or positioning of the separating device relative to the cover material 20 and the base material web 10. For example, the sensor can be configured to detect the alignment and / or positioning of the adhesive regions 12 and provide information about them to the control unit. The control unit can be configured to control an alignment and / or positioning of the separating device relative to the cover material 20 and the base material web 10, at least partially based on the provided information.

[0131] Fig. 3 and 4show an embodiment of a label 100 according to the invention, which in a separation step of the method according to the invention by means of at least one separation device from the Fig. 2 shown label strip 60 was cut out.

[0132] The label 100 comprises a base material 110 with at least one adhesive region 112 to which an adhesive is applied. The base material 110 was prepared from the Fig. 1 and 2 shown base material web 10. Although the Fig. 3 and 4 While the label 100 shown has only one adhesive region 112, the label 100 may alternatively have a plurality of adhesive regions 112.

[0133] The label 100 also has an adhesive-free edge 122 that extends completely around the adhesive area 112 and to which no adhesive is applied. The adhesive-free edge 122 includes a portion of the Fig. 1 and 2shown adhesive-free areas 16, which are arranged between adjacent adhesive areas 12 of a respective row 14a, 14b and space them apart. The adhesive-free edge 122 also comprises a part of the Fig. 1 and 2 shown adhesive-free areas 18, which are arranged between the rows 14a, 14b of the adhesive areas 12 and space them apart from one another.

[0134] The label 100 also has a cover material 120 that completely covers the adhesive area 112 and covers at least a portion of the adhesive-free edge 122. The cover material 120 was made from the Fig. 2 shown cover material 20 is cut out.

[0135] The adhesive region 112 is arranged between the base material 110 and the cover material 120. Thus, the adhesive region 112, from the perspective in Fig. 3 , hidden beneath the cover material 120.

[0136] The base material 110 also has an opening 124 which can serve, for example, as a fastening means, in addition to the adhesive, for attaching the label 100 to objects.

[0137] In the areas 126, 128, the cover material 120 is flush with the adhesive-free edge 122 of the base material 110 (see Fig. 3 ). In Fig. 4 the areas 126, 128 are directed out of the drawing plane or into the drawing plane, so that the flush finish of the cover material 120 with the adhesive-free edge 122 of the base material 110 in Fig. 4 cannot be seen.

[0138] Figs. 5 and 6 show a further variant for producing a label strip 160 which has essentially the same, or at least similar, features as the label strip 60 from Fig. 2 The same, or at least similar, features are found in Figs. 5 and 6 therefore with the same reference numerals as in Fig. 1 and 2 provided.

[0139] In contrast to the label tape 60, the Fig. 6 The label strip 160 shown has a plurality of cover material strips 20A, 20B, 20C, 20D along the rows 14a, 14b of the adhesive regions 12. Each cover material strip 20A, 20B, 20C, 20D is arranged on an adhesive region 12. The cover material 20 can be provided, for example, as a web which, before the cover material 20 is joined, preferably laminated, to the base material web 10, is separated into the individual cover material strips 20A, 20B, 20C, 20D, which can then be joined, preferably laminated, to the base material web 10. As a result, no cover material 20 is arranged in an area of ​​the adhesive-free regions 16, as in Fig. 6 can be seen.

[0140] Figs. 7 and 8show a further embodiment of labels 200A, 200B according to the invention, which in a separation step of the method according to the invention by means of at least one separating device from the Fig. 6 shown label strip 160 were cut out.

[0141] The Figs. 7 and 8 The labels 200A, 200B shown have essentially the same, or at least similar, features as the label 100 from the Fig. 3 and 4 The same, or at least similar, features are found in Figs. 7 and 8 therefore with the same reference numerals as in Fig. 3 and 4 provided.

[0142] In contrast to the label 100, which was completely separated from the label strip 60 as a single label, the labels 200A, 200B are designed as label strips 201 with a plurality of individual labels 200A, 200B that are at least partially connected to one another. Fig. 7Two interconnected individual labels 200A, 200B are shown. However, this is merely an example. More than just two individual labels 200A, 200B can be interconnected in a label strip 201.

[0143] To produce the label strip 201, analogous to label 100, the label tape 160 can be completely separated along the dividing line 24b to form individual label strips 201. In contrast to the label 100, which was formed, among other things, by a complete separation along the dividing lines 24a and 24b, to produce the labels 200A, 200B, however, the label tape 160 can only be perforated along the dividing line 24a to form a perforation line 203 between the labels 20A, 200B.

[0144] As a result, the label strip 201, preferably wound up in a roll, can be arranged, for example, in a label dispenser in order to remove individual or multiple labels 200A, 200B from the label dispenser and to tear them off along the perforation line 203 and use them accordingly.
