<p>A system (10) for analysing web breaks in a printing press, comprising sensing devices (12, 14) for monitoring the web and the printing press and detecting a web break, characterised by a database (24) with predetermined web break causes, for each of the predetermined web break causes, a real cause probability calculation algorithm for calculating the probability that the corresponding predetermined web break cause is the real cause of a detected web break as a function of said sensing devices' (12, 14) outputs, and a real web break cause determining processor (20) for executing each real cause probability calculation algorithm, ranking the predetermined web break causes according to their calculated real cause probabilities, and identifying the web break cause amongst the predetermined web break causes with the highest real cause probability as the cause for said detected web break.</p> |
