Abstract (en)

[origin: WO03080928A1] The invention concerns a method and system for maintaining runnability in a paper or board machine, which machine for making paper or board includes two or more successive section complexes, such as a web formation section (10), a press section (11), a drying section (12) and a finishing device (13), and wherein at the section complex (10 - 13) (i) cleaning measures are carried out, (ii) the cleanness level is checked, (iii) if the cleanness level does not meet the criteria established for it, the procedure continues from step (i), otherwise, (iv) the cleanness level is accepted. Checking of the cleanness level is performed by using computer vision and the observations obtained by computer vision are compared with a criterion value established to correspond with the required cleanness level, and based on this value the procedure either continues with cleaning measures (i) or the cleanness level is accepted (iv).
