Problems solved by technology

Disadvantageously, this identification on the flat side of the metal strip will be lost after the coil has been severed (for example when carrying out end-side cutting of the strip end)
Also, all strip sections separated from the coil, such as sheets, slitting strips, flat strips, etc., lack any markings except for the sheet sections at the end sides
As a result, at least retroactive tracking of band segments is made difficult or not possible at all
and it is no longer possible to retroactively deduce the location of the strip segments on the original metal strip

Embodiment Construction

[0030] according to figure 1 For example, a metal strip 2 , ie an aluminum strip, wound into a coil 1 or coil is shown according to the first embodiment, which has markings 3 on the flat side 2 . 1 for preferably unambiguous identification of the coil 1 . Markings 3 are printed onto the metal strip 2 . However, this marking 3 can also be provided on a label glued to the metal strip 2 , which is not shown in detail in the figures.

[0031] According to the invention, the printed marking 3 has an information track 4 . This information track 4 is arranged over the entire length L of the metal strip 2 , more precisely in the region of the longitudinal edges of the metal strip 2 . Furthermore, this information track 4 has successively arranged words 5.1, 5.2, 5.3, 5.4, 5.5 of the De Bruijn sequence 5 . For better clarity, the words 5.1, 5.2, 5.3, 5.4, 5.5 are separated from each other by spaces in figure 1 is shown in , but it is entirely conceivable to form tag 3 without space...

Abstract

The invention relates to a coil (1) made of a coiled metal strip (2), in particular an aluminum strip, having a marking (3, 103) on a flat side (2.1) of the metal strip (2). The aim of the invention is, inter alia, to be able to clearly identify the strip segments (7) severed from said coil (1). This aim is achieved, according to the invention, in that, for allocating strip segments (7) severed from the coil (1), the marking (3, 103) assigns the coil (1) and the original position of the marking on the coil(1) an information track, preferably extending across the entire strip length (L) of themetal strip (2), comprising a de-Bruijn sequence (5) of successively arranged words (5.1, 5.2, 5.3, 5.4, 5.5 or 5.6 to 5.25) of said de-Bruijn sequence, or of a subset of the words (5.1, 5.2, 5.3, 5.4, 5.5 or 5.6 to 5.25) of said de-Bruijn sequence.

Description

technical field [0001] The invention relates to a coil made of a wound metal strip, in particular an aluminum strip, which has markings on the flat side of the metal strip. Background technique [0002] It is known from the prior art to mark coils produced from coiled or capstan-wound metal strips on the end sides in order to thereby give the coils a clear identification. The disadvantage is that this identification on the flat side of the metal strip is lost after the coil has been severed (for example when the strip end is cut sideways). Furthermore, all strip sections separated from the coil, such as sheets, slit strips, flat strips, etc., except for the end-side sheet sections, lack any markings. As a result, at least the retroactive tracking of the tape sections is made difficult or not possible at all. Furthermore, it is no longer possible to retrospectively deduce the position of the strip sections on the original metal strip. Contents of the invention [0003] T...
