Process for Identifying and Correcting Defects or Non-Conformities on Self-Adhesive Labels or Patters Made on a Continuous Band

Abstract: a process for identifying and correcting defects and/or non-conformities on patterns and/or labels present on a continuous band comprises the steps of advancing the continuous band () so as to expose the labels or the pattern to first inspection means (), which detect the presence of any defects and/or non-conformities, and, if detected, keep the portion of the continuous band () containing the defect and/or non-conformity steady at a correction station (), from which the portion of the continuous band () containing the defective label or non-conforming section of the pattern is removed and/or replaced, then checking, by means of second inspection means (), the absence of defects and/or non-conformities in the portion of the continuous band () from which the defective label or the non-conforming section of the pattern has been removed and/or replaced.
