PROCÉDÉ ET SYSTÈME DE SURVEILLANCE DES CARACTÉRISTIQUES DES DÉFAUTS DANS UNE BANDE DE MATÉRIAU QUI SE DÉPLACE DANS UNE MACHINE DE PRODUCTION DE LA BANDE ET D'IDENTIFICATION DES CAUSES DES DÉFAUTS DANS LA BANDE DE MATÉRIAU

摘要

Monitoring continuous repetitive web sheet defects to determine the causes of such defects by creating unique diagnostic patterns associated with selected components of a web-making machine and employing pattern recognition techniques to analyze and classify web-sheet dynamic and deterministic defect patterns, and identify their root causes. Corrective actions can be effected thereby enhancing machine run-time to minimize late deliveries and improves overall product quality. The technique which is integrated with quality control system can be applied to the manufacturer of paper, packaging, rubber sheets, plastic film, metal foil, and the like.
