Definitions

  • the invention relates to a collar made of a wound metal strip, in particular aluminum strip, with a marking on a flat side of the metal strip.
  • the marking has an information track provided over the, preferably entire, length of the metal strip
  • information can first be given to each strip section separated from the metal strip, by means of which information can at least be drawn about the collar from which the strip section has been cut off. An assignment of band sections separated from the federal government to the federal government is thus possible. If this information track also has a de Bruijn sequence of words of this de Bruijn sequence arranged one after the other, the respective marking on the cut strip sections can also be used to determine their original position in the metal strip.
  • each separated section of the tape there is at least one word once as a partial sequence of the de Bruijn sequence, for example B (k, n) above a, preferably alphanumeric, alphabet with a quantity of k characters and a length n of words.
  • B (k, n) a partial sequence of the de Bruijn sequence
  • a, preferably alphanumeric, alphabet with a quantity of k characters and a length n of words.
  • this information track can also have a de Bruijn sequence from a subset of the words in this de Bruijn sequence, which not only allows the former position of the band section on the band to be determined, but also makes it possible to differentiate from which bundle the band section in question originates .
  • Each covenant has a clear section of the de Bruijn sequence via the partial sequence, which makes it possible to use the section to identify the covenant from which the band section originates.
  • Known data on the information track on the tape can be used, for example, to draw conclusions about the position of this tape section on the tape on the basis of a word or possibly several words on the tape section.
  • the information track is comparatively easy to read visually and is easy to process, in particular also by machine.
  • the words of the de Bruijn sequence can be formed from an alphabet with distinguishable symbols.
  • Such an alphabet can be made up of symbols, colors, characters, letters, numbers, Morse codes etc. or a combination thereof.
  • the information track can have a one-dimensional or two-dimensional de Bruijn sequence.
  • the one-dimensional de Bruijn sequence also makes it easier to process the information track - such as reading it out and thus making data available.
  • the de Bruijn sequence can preferably have the order k and words of length n.
  • a de Bruijn sequence of order 10 with words of length greater than or equal to 6 has proven to be particularly robust for marking a bundle.
  • the words of the de Bruijn sequence are formed from an alphanumeric or numeric alphabet, this can further facilitate the processability of the information track, such as reading out and thus also making data available.
  • the information track has the same identification before and / or after each word of the de Bruijn sequence, in addition to information about the former position of the tape section on the tape, fixed information can also be provided on the tape section - for example information about the tape, the producer, the customer, the date of production etc.
  • One or more characters of the, preferably alphabetic, alphabet, for example Latin letters, can be suitable for the labeling, for example.
  • the alphabet of the identification preferably differs from the alphabet of the de Bruijn sequence in order to be able to separate the identification and de Bruijn sequence more easily. This can further facilitate the processability of the information track.
  • a marking is used on a flat side of a metal strip wound into a bundle
  • the marking an information track provided over the, preferably entire, length of the metal strip with a de Bruijn sequence of words of this de Bruijn sequence arranged one after the other or from a subset of the words of this de Bruijn sequence, it can be possible to assign band sections separated from the bundle both to the bundle and to their original position on the bundle.
  • the information track on the severed band section On the basis of a part of the information track on the severed band section, unambiguous information on the position on the metal band of the bundle or on the relevant origin band is available.
  • the assignment of band sections separated from the bundle to their original position on the bundle is thus possible.
  • the information track is comparatively easy to read visually and is easy to process, in particular also by machine.
  • the information track can have a one-dimensional or two-dimensional de Bruijn sequence.
  • the one-dimensional de Bruijn sequence also makes it easier to process the information track - such as reading it out and thus making data available. The handling of the information track used can thus be facilitated.
  • the de Bruijn sequence can preferably have the order k and words of length n.
  • a de Bruijn sequence of order 10 with words of length greater than or equal to 6 has proven to be particularly robust for marking a bundle.
  • a sufficiently long de Bruijn sequence can be ensured if the words of the de Bruijn sequence are formed from an alphanumeric or numeric alphabet. In addition, this can further facilitate the use of the information track, such as reading out and thus also making data available.
  • Information about the tape, the producer, the customer, the production date etc. can be reliably added to the marking if the information track before and / or after each word of the de Bruijn sequence has the same marking, for example from one or more Signs of the, preferably alphabetic, alphabet.
  • the alphabet of the marking preferably differs from the alphabet of the de Bruijn sequence in order to be able to distinguish between the marking and the de Bruijn sequence more easily. This can further facilitate the processability of the information track.
  • a hash value is formed over the information track of the federal government, this can be used to check the authenticity and / or integrity of data and / or a document that relates to the federal government or to those separated from it Band sections are related. Data with this hash value or a document with this hash value, for example: a delivery note, electronic documents, etc., can thus be clearly assigned to a federal government. Forgeries, manipulation, etc. are easily recognized.
  • a metal strip 2, namely aluminum strip, wound up to form a bundle 1 or coil is shown according to a first exemplary embodiment, which has a marking 3 for preferably uniquely identifying the bundle 1 on a flat side 2.1.
  • the marking 3 is printed on the metal strip 2.
  • this marking 3 can also be provided on a label glued to the metal strip 2, which is not shown in more detail.
  • this printed marking 3 has an information track 4.
  • This information track 4 is provided over the entire length L of the metal strip 2 - preferably in the area of the longitudinal edge of the metal strip 2.
  • this information track 4 has words 5.1, 5.2, 5.3, 5.4, 5.5 of a de Bruijn sequence 5 arranged one after the other . These words 5.1, 5.2, 5.3, 5.4, 5.5 are separated from one another by spaces in the figure for better illustration Fig. 1 shown - but it is quite conceivable that the marking 3 is free of spaces - as in the Fig. 2 can be seen at the marking 103.
  • de Bruijn sequence B (5.3) above the, preferably numerical, alphabet ⁇ 0,1,2,3,4 ⁇ made up of, in particular, natural numbers.
  • the words 5.1, 5.2, 5.3, 5.4, 5.5 thus have the length n, namely 3, and the de Bruijn sequence B (k, n) has the order k, namely 5.
  • the de Bruijn sequence B (5.3) are in Fig. 1 the words ⁇ 402 ⁇ , ⁇ 301 ⁇ , ⁇ 201 ⁇ , ⁇ 101 ⁇ and ⁇ 401 ⁇ recognizable.
  • each word 5.1, 5.2, 5.3, 5.4, 5.5 of the de Bruijn sequence occurs only once in the information track 4 on the metal strip 2.
  • the information track 4 in front of each word 5.1, 5.2, 5.3, 5.4, 5.5 of the de Bruijn sequence B (5, 3) has the same identification 6, namely "amag", which denotes the manufacturer. It is also conceivable to provide the bundle number, manufacturer code etc. in the information track 4 via the identification 6. For this same identification 6, several characters of the alphabetical alphabet from, for example, Latin letters are used.
  • the numerical alphabet of the words of the de Bruijn sequence and the alphabetic alphabet of the marking 6 make the marking 3 easy to read visually and therefore stable to process. According to the invention, it is thus possible, even after a strip section 7 has been severed from the metal strip 2, via the information track 4 remaining on the strip section 7, not only the original collar with the identification "amag", but also via the word 5.1, namely ⁇ 401 ⁇ , and / or infer the word 5.2, namely ⁇ 101 ⁇ , to the original position of the band section 7 on the metal band 2 of the collar 1.
  • the information track 4 is also comparatively easy to recognize visually and its information is therefore easy to process.
  • the information track 4 has a subset of all the words of the Bruijn sequence B (5, 3).
  • a Bruijn sequence B (5, 3) can thus be used to mark several frets with a clear identification of the band sections 7 separated from them.
  • Fig. 1 In contrast to Fig. 1 is the mark 103 on collar 1 after Fig. 2 provided in the second embodiment on the flat side 2.1 along opposite longitudinal sides 2.2, 2.3. In this way, the marking 103 can also remain on a strip section 7 which has been split into two split strips 7.1, 7.2.
  • the marking 103 has a page numbering 8 - namely 1 or 2 - in order to be able to recognize on the slit band 7.1, 7.2 which side is the split band section 7.
  • a label 6, namely "amag” can be found in the information track 4.
  • This label 6 is the same as for Fig. 1 in the de Bruijn sequence B (5.3) between two words 5.6-5.24 of the de Bruijn sequence B (5.3). As shown, however, the marking 6 is provided after 5 words 5.6-5.10, 5.11-5.15, 5.16-5.20 and 5.21-5.25 of the de Bruijn sequence B (5.3).
  • the words 5.6-5.10 namely ⁇ 000 ⁇ , ⁇ 001 ⁇ , ⁇ 010 ⁇ , ⁇ 100 ⁇ , ⁇ 002 ⁇
  • the words 5.11-5.15 namely ⁇ 003 ⁇ , ⁇ 030 ⁇ , ⁇ 301 ⁇ , ⁇ 011 ⁇ , ⁇ 110 ⁇
  • the words 5.16-5.20 namely ⁇ 130 ⁇ , ⁇ 302 ⁇ , ⁇ 021 ⁇ , ⁇ 210 ⁇ , ⁇ 102 ⁇
  • the words 5.21-5.25 namely ⁇ 202 ⁇ , ⁇ 023 ⁇ , ⁇ 230 ⁇ , ⁇ 303 ⁇ , ⁇ 031 ⁇ are also arranged one after the other.
  • a hash value is formed from the information track 4 over the, preferably entire, information track 4 of the bundle 1. For example, from "0001002a-mag0030110amag120" of information track 4, using hash function CRC32, hash value 5ce0c22a is formed. This hash value 5ce0c22a represents one clear reference to information track 4. If data or a document are linked or provided with the hash value, the authenticity and / or integrity of this data or this document can be checked.
