Abstract (en)

[origin: EP2319787A2] The invention relates to a method for controlling the slitting of a web-like material on the slitter-winder, in which method, slitting the web into several partial webs which are wound into partial web reels, and monitoring the travel of the web on the slitter-winder with a monitoring device (100) which automatically detects events deviating from the normal winding such that an image is created of a monitoring area (104) being monitored and, triggered by a fault detected in the image, taking measures to eliminate the fault or to minimise its effects. In the method, determining in the monitoring area a fixed point and, simultaneously when an image is created of the monitoring area (104) being monitored substantially continuously, determining the position of the fixed point and, if the position of the fixed point changes more than pre-determined, re-determining the position of the monitoring area such that the monitoring area (104) is located in a new place determined by the changed position of the fixed point.
