摘要
A method and system for monitoring web defects along a moving web (10) of paper involves determining a dimension of a web defect (14) as the paper web (10) moves along an established paper path in a machine direction (12). A distance from a side edge of the paper web (10) to a location of the web defect (14) is also determined as the paper web (10) moves along the established paper path. A value indicative of a likelihood of paper web failure at the web defect (14) is then established based at least in part upon both the determined dimension and the determined distance. A determination of whether to stop the moving paper web (10) for repair of the web defect (14) can then be made based at least in part upon the determined failure likelihood indicative value. An alternative technique involves establishing a plurality of paper web width regions. A dimension of a web defect (14) is determined as the paper web (10) moves along an established paper path in a machine direction (12). The web defect (14) is categorized as falling into one of the established paper web width regions. A determination of whether to repair the web defect (14) can then be made based at least in part upon the determined dimension and the categorization made.
