Abstract (en)
The invention relates to a method for computer-implemented tracking of production history of a continuous web (5), which is processed in a production system (1), comprising at least one sub-system (10) applied to perform one or more specific operations. The web (5) is transported along a curved given path (P) through the production system (1) by winding/unwinding from/onto a coil (11, 23). The following steps are performed at each time point of one or more time points during the operation of the production system (1):a) obtaining measured data (MD) of the web (5) while being transported along the path (P), the measured data (MD) being current time-stamped measured data (MD) acquired by at least one of a sensor (31, 32, 33) or a measuring device installed at or in the vicinity of the production system (1) along the path (P), where a spatial position of each sensor (31, 32, 33) and measuring device with respect to the given path (P) is known;b) obtaining movement information (MI) of the web (5);c) determining production-relevant features (PRF) of the web (5) by processing the time-stamped measured data (MD) and the movement information (MI) of the web (5) by mapping the time-stamped measured data (MD) to physical points of regions of the web (5).
