Definitions

  • the invention relates to a method for producing a multiple-use strip which is provided for application to a target substrate, further relates to the multiple-use strip and relates to the corresponding use for application to the target substrate.
  • Data carriers such as value or identity documents, but also other objects of value such as branded items, are often provided with security elements for protection that allow the authenticity of the data carrier to be checked and at the same time serve as protection against unauthorized reproduction.
  • Security elements can for example be integrated into the substrate of the data carrier or applied to the substrate of the data carrier.
  • a multiple use strip, on which several security elements are arranged one behind the other, can be applied to a multiple use, such as a sheet of banknotes which comprises several individual uses.
  • the position of the multiple-use strip for multiple-use is irrelevant in many applications. In some cases, however, a precisely positioned application is sometimes also desired.
  • EP 2 848 425 A2 it is proposed to create several security elements one behind the other and spaced apart from one another on an endless web as an intermediate carrier.
  • the security elements are thus created in exactly the form in which they are to be applied to a target substrate.
  • a created area is brought into the outer shape of the security element either before application and / or during application to the target substrate.
  • WO 2015/124227 A1 shows a tax stamp in the edge area of a multi-up strip that includes several individual copies.
  • Multi-use strips are created on an intermediate carrier, the multi-use strip being intended to be placed on or in a multi-use area of the target substrate.
  • the multi-use strip comprises a security element and an area surrounding the security element for each individual use. Perforations for anchoring the multiple-use strip to the target substrate can be provided in the single-up if the multiple-use strip is introduced during the production of the target substrate.
  • the intermediate carrier is an intermediate carrier web on which several of the multi-use strips are created next to one another. The intermediate carrier web is cut into several strip partial webs, on each of which several of the multi-use strips are arranged one after the other lengthwise.
  • the invention is based on the object of specifying a flexible method which, in particular, ensures good positioning.
  • the present method for producing multi-use strips comprises at least the following steps.
  • Multi-use sections are created on an intermediate carrier, the multi-use sections being provided for application to a multi-use area of a target substrate.
  • two outer sections are created on the intermediate carrier, which are provided for application to outer areas of the target substrate.
  • the two outer sections of a multi-use section together with the multi-use section form a multi-use strip.
  • the length of the multi-utility section lies between its two outer sections.
  • the outer sections of the multi-use strip are pre-structured on the intermediate carrier for the application of the multi-use strip to the target substrate.
  • the intermediate carrier is an intermediate carrier web on which several of the multi-use strips are created next to one another.
  • the intermediate carrier web is cut into several strip partial webs on which several of the pre-structured multi-use strips are arranged one after the other lengthwise.
  • the multi-use strip can also be transferred to the target substrate using a conventional device. Any positional inaccuracy during the pre-structuring does not have a negative effect on the positioning of the multi-use section.
  • the pre-structuring in the outer section prevents the multi-utility section from being impaired by the pre-structuring.
  • Mechanical pre-structuring can lead, for example, to deformations, optical pre-structuring by means of laser, for example, for early thermal activation of a pressure-sensitive adhesive, and chemical pre-structuring, for example through diffusion effects, in the multi-use section.
  • the pre-structuring is preferably carried out offset longitudinally with respect to one another.
  • any possible — in particular mechanical — loading of the intermediate carrier web triggered by the pre-structuring can be spatially distributed (and thus locally reduced).
  • the outer portion preferably comprises a minimum portion that is applied to the target substrate and a pre-structuring portion. For two (adjacent or) consecutive multiple-use strips An intermediate area can lie between two outer sections, in particular between the two pre-structuring sections.
  • a pre-structuring offset is possible regardless of the position of the multi-use sections on the intermediate carrier web.
  • the multiple-use sections lying next to one another can be present on the intermediate carrier web without being offset (identical) to one another.
  • the position of the pre-structuring can vary within the pre-structuring section (and / or the intermediate area).
  • the length of the minimum sections can be varied in order to obtain a pre-structuring offset.
  • At least the multiple-use strips lying next to one another are created offset longitudinally to one another.
  • a multi-use strip offset on the intermediate carrier web can contribute to a pre-structuring offset, that is to say generate or enlarge it.
  • the pre-structuring offset is preferably greater than 4 mm.
  • the multi-use strip is applied to the target substrate with a position tolerance.
  • This position tolerance depends on the device used; it is usually between 0.5 and 1 mm, but in any case less than 2 mm.
  • the position tolerance indicates the maximum deviation of the actual position of the multiple-use strip on the target substrate in relation to a reference position, that is to say the position of the multiple-use area.
  • the pre-structuring offset is preferably greater than twice the position tolerance.
  • the minimum section is preferably greater than twice the position tolerance.
  • a pre-structuring tolerance can be greater than the position tolerance.
  • the size of the pre-structuring tolerance has no influence on the positioning tolerance. In the case of pre-structuring, work can therefore be carried out more cost-effectively or with less control effort.
  • the intermediate carrier web comprises a primary carrier and a secondary carrier.
  • the secondary carrier is usually laminated onto the primary carrier.
  • a laminating adhesive layer preferably has a thickness of 2 to 3 ⁇ m.
  • the primary carrier is laminated onto the secondary carrier (on the back of the secondary carrier) before the step of pre-structuring the multiple-use strips.
  • the pre-structuring is carried out by means of laser radiation, it is conceivable to protect the primary carrier by means of a non-laserable barrier layer, for example a copper layer, which is provided between the primary carrier and the secondary carrier.
  • the primary carrier is only laminated onto the secondary carrier (on the back of the secondary carrier) after the step of pre-structuring the multiple-use strips.
  • This configuration increases the flexibility in the pre-structuring and guarantees the required stability.
  • different primary carriers can be laminated and / or can be pre-structured differently.
  • the primary carrier web is laminated onto the back of the secondary carrier web, so the laminating takes place before the intermediate carrier is cut.
  • the later lamination possibly in connection with an offset, enables pre-structuring that sever, remove or cut out the primary carrier (and the multi-use strip) over the entire width of a partial strip web.
  • the created outer section is pre-structured in particular mechanically, chemically or by means of radiation.
  • the pre-structuring corresponds to a local or area-wise change of the created outer section.
  • the pre-structuring extends over the entire width of the partial strip web (or over the length of the pre-structuring section). In particular, it can serve to avoid contamination, for example from fragments of the multiple-use section, as is known for multiple-use sections with embossed lacquer layers.
  • the pre-structuring can also be useful in order to support reliable application to the target substrate, in particular if adhesion problems could otherwise arise when the intermediate carrier is detached from the multi-use section.
  • Lasing, UV irradiation and / or (ultra) sound-based methods are particularly conceivable as irradiating pre-structuring.
  • Mechanical pre-structuring can include perforating, punching out, stamping out or pressing.
  • Chemical pre-structuring can include local removal (etching) or local change (e.g. locally softening brittle embossing lacquer).
  • the pre-structuring can take the form of an individual pre-structuring, as a pre-structuring that is repeated in a partial area or as a uniform or repeating pre-structuring over the entire pre-structuring section be designed.
  • a pre-structuring can also extend over a partial area or the entire area of the pre-structuring section, in particular in that a continuous pre-structuring continues in a pattern or meandering manner over the partial area or the entire area.
  • Outer sections of two adjacent multi-use sections are particularly preferably jointly pre-structured.
  • these two outer sections can comprise a common pre-structuring section.
  • a positioning aid for positioning the multi-use section relative to the target substrate and / or a production identifier is created which uniquely identifies the multi-use strip, the partial strip web and / or the intermediate carrier web. If the positioning aid is created together with the multi-up section - and not independently of it, for example during pre-structuring - there are no additional tolerances.
  • a production identifier uniquely identifies the multi-use strip, the partial strip web and / or the intermediate carrier web, at least in the production system. It can thus be recorded and stored which components have been processed or which component is at least partially contained in which end product, such as a bank note.

  • No metal layer is arranged in the minimal outer section 26 of the multi-use strip 25.
  • the outer section is free of motifs.
  • the embossing lacquer layer 823 is therefore generally unembossed, that is to say without a relief structure.
  • the layers 821, 822, 824, 825 and 826 that do not form a motif are present in the outer section as well as in the multi-use section.
  • the embossing lacquer layer 823 (and underlying layers 821 and 822) extends into the prep area. In the preparation area, at least the embossing lacquer layer 823 is pre-structured on both sides.
  • the two pre-structuring 88 extend into the primary carrier 833. It is conceivable, but not necessary in the present embodiment, to provide a plurality of pre-structurings next to one another or to provide the section 28 with a large number of pre-structurings. Without a secondary carrier 831, a partial strip web with multi-use strips could tear (positioning problem) or, in extreme cases, even tear through.
  • the pre-structuring 88 can be produced, for example, by perforating or cutting into a corresponding depth, in particular by means of a laser or mechanically.
  • Positioning aids 82, 86 and a production identifier 84 are in relation to the other layers in FIG Figure 8 recognizable. Your respective function is now based on Figure 9 described.
  • Figure 9 shows - analogous to Figure 2 - A partial strip web with several multi-use strips 20 in plan. Therefore, only the additional elements will be discussed.
  • a positioning aid 86 can be created in the outer section 22, which indicates the exact position of the multi-use section.
  • the positioning aid 86 for the multi-use section like an optional positioning aid 82 for the pre-structuring section 27, is also created in the step of creating the outer section.
  • the positioning aids 82 the position of the pre-structuring can be determined for the pre-structuring step.
  • the (possibly different) Length of the outer sections 22 and the width of the intermediate sections 23 are generated or taken into account.
  • a production identifier 84 is a one-to-one identification, for example in the form of a number or a barcode.
  • the production identifier 84 uniquely identifies the multi-use strip, the partial strip web and / or the intermediate carrier web, at least in the production system. It can be recorded and saved automatically when the multiple-use strip is applied or in a subsequent production step. On the basis of the recorded data, it is possible to understand which components have been processed or which component, such as individual utility strips as a security element, in which end product, such as bank note, is at least partially contained.
