Abstract
The invention relates to a method for monitoring a rapidly-moving paper web. In the method, images of the rapidly-moving web are taken with cameras at several consecutive positions, of the same cross-direction point of the web. The images are analysed in real time in order to detect deviations, and the position data of the deviations are determined. Each deviation found in the analysis is connected to an event chain in real time using a selected criterion on the basis of the position data of each deviation. Images containing a deviation are shown to the operator immediately as event chains.
