摘要： This disclosure describes techniques for automatically controlling the operation of a slitter (40) to convert a web (20) of material into smaller slit rolls (64, 66, 68). A slitter director (60) may automatically control the operation of a slitter (40) for defect removal, web splicing, and/or slit roll rejection based on continually registering previously-generated anomaly data (62) with physical locations of the web (20).
