Abstract: Method for predicting the presence of product defects during an intermediate processing step of a thin product wound in a roll, which provides for—receiving a roll of thin product that has been assigned a unique identification code stored in a database system, this latter containing process and/or product parameters detected in the production steps of said thin product wound in said roll upstream of said intermediate processing step, associated with said unique identification code, —accessing said database system, —entering one or more of the process and/or product parameters associated with the unique identification code of said roll contained in said database system in a predictive model, which uses a correlation, created by means of machine learning logics, from historicized values related to the process and/or product parameters output from said intermediate processing step and historicized values related to process and/or product parameters of the same rolls detected in the production steps of said rolls upstream of said intermediate processing step, in order to predict product parameters output from said intermediate processing step, —comparing said aforesaid product parameters with respective predefined limit values, —generating predictive diagnosis information of thin product defects based on the result of said comparison.
