Abstract
A coil made of a coiled metal strip, in particular an aluminum strip, having a marking on a flat side of the metal strip. In order to be able, inter alia, to clearly identify the strip segments severed from the coil it is proposed that the marking, for allocating strip segments severed from the coil to the coil and the original position of the marking on the coil, comprises an information track, preferably extending across the entire strip length of the metal strip having a de-Bruijn sequence of successively arranged words of said de-Bruijn sequence or from a subset of the words of said de-Bruijn sequence.

A coil made of a coiled metal strip, comprising a marking on a flat side of the metal strip, wherein the marking is used for allocating strip segments separated from the coil to the coil and an original position of the marking on the coil, and the marking comprises an information track, extending across a strip length of the metal strip having a de-Bruijn sequence of successively arranged words of said de-Bruijn sequence or from a subset of the words of said de-Bruijn sequence.
A method of using a marking on a flat side of a metal strip wound into a coil, comprising using a marking that comprises an information track provided over a strip length of the metal strip and having a de-Bruijn sequence of successively arranged words of said de-Bruijn sequence or of a subset of the words of said de-Bruijn sequence, for assigning strip segments separated from the coil both to the coil and to an original position of the strip segments on the coil.
