The scanning device (22) is configured to continuously scan a surface (25) of the moving web (21) and generates output data representative of the surface of the web. The data processing circuitry (23) is responsive to selected output data representing at least one type of surface anomaly (26) such that Region Of Interest (ROI) data are automatically recorded. This ROI data represents the detected anomaly (26) and an immediate surrounding region (27) including the detected anomaly. The hands-free data processing circuitry (23) continuously monitors and analyzes the output data generated by the scanning device (22) while the ROI data is being stored. A storage device (28) is coupled to the data processing circuitry (23) for storage of the selected ROI data.Field of SearchWeb, sheet or filamentFlaw detector Of surface (e.g., texture or smoothness, etc.) Manufacturing or product inspection With circuit for evaluating a web, strand, strip, or sheet Evaluation by regions, zones, or pixels With imaging With scanning With imaging INSPECTION OF FLAWS OR IMPURITIES Textile inspection Elongated textile product (e.g., thread, yarn, etc.) Detection of foreign material (e.g., trash, splinters, contaminants, etc.) | |
