Preferential defect marking on a web
First Claim
1. A method comprising:
- obtaining a web to be converted into individual sheets of a plurality of different grade levels;
associating a unique mark with each of the different grade levels;
obtaining anomaly data that identifies positions of anomalies on the web for each of the grade levels, wherein each of the anomalies represents a physical deviation of the web that is a potential defect for at least one of the plurality of different grade levels; and
marking the position of each anomaly on the web at the position of the anomaly, wherein each anomaly is marked with each of the marks corresponding to each of the grade levels for which the anomaly is determined to be a defect.

Abstract
A system for preferentially marking defects on a web is described. The system includes a web of material to be converted into individual sheets of a plurality of different grade levels, a database storing anomaly data of anomalies on the web, wherein an anomaly is a potential defect in at least one of the plurality of different grade levels, a marker that associates a unique mark with at least one of the grade levels, and a controller to retrieve the anomaly data from the database and to signal the marker as to where to make a mark, wherein the marker applies the mark associated with at least one of the grade levels for which the anomaly may cause a defect. The system may provide advantages, such as that a converter of various products from a single web roll may determine which regions of the web satisfy each grade level.

19. A method comprising:
-
receiving a web to be converted into individual sheets of a plurality of different grade levels, wherein the web has marks to indicate positions of anomalies on the web, wherein the marks include a unique mark for each of the different grade levels; separating the web into the individual sheets; selecting, for each individual sheet, one or more of the products into which to incorporate the sheet in accordance with the marks; and incorporating each sheet into the selected product or products. - View Dependent Claims (20, 21, 22)

23. A system comprising:
-
a web of material to be converted into individual sheets of a plurality of different grade levels; a database storing anomaly data of anomalies on the web, wherein an anomaly is a potential defect in at least one of the plurality of different grade levels; a marker that associates a unique mark with at least one of the grade levels; and a controller to retrieve the anomaly data from the database and to signal the marker as to where to make a mark, wherein the marker applies the mark associated with at least one of the grade levels for which the anomaly is determined to be a defect. - View Dependent Claims (24, 25, 26)

27. A non-transitory computer-readable medium comprising instructions stored therein for causing a programmable processor to perform:
-
retrieving web identifying information, wherein the web is to be converted into individual sheets of a plurality of different grade levels; associating a unique mark with each of the grade levels; obtaining anomaly data that identifies positions of anomalies on the web for each of the grade levels, wherein each of the anomalies represents a physical deviation of the web that is a potential defect for at least one of the plurality of different grade levels; and signaling a marker to mark the position of each anomaly on the web at the position of the anomaly, wherein each anomaly is marked with each of the marks corresponding to each of the grade levels for which the anomaly is determined to be a defect.
