Abstract: A converting line for producing a paper product. The converting line includes a paper web being unwound from a parent roll. The paper web has a plurality of sections with at least one mark having a paper rating assigned to each of the plurality of sections. The converting line also includes a mark reading unit that reads at least one of the plurality of marks on the paper web and produces a corresponding output. The converting line includes a controller that receives the output from the mark reading unit, and is configured: (i) to obtain the paper rating associated with the at least one mark read by the reading unit, and (ii) to change at least one operational parameter of the converting line based upon the paper rating. The converting line also includes a finisher. The paper web is fed to the finisher and converted into a paper product.

Abstract: A paper web and a method of marking a paper web. The paper web includes a surface having a plurality of sections. At least one section of the plurality of sections has a plurality of positions. The plurality of positions each have an equal length and are obtained by subdividing the at least one section. The paper web also includes ink applied to the surface of the paper web at some of the plurality of positions. The method includes applying a first mark and a second mark to a paper web. The first mark has a start position and is coded to convey an identifier for the paper web. The second mark includes a start position and is coded to indicate a position on the paper web. The start position of the second mark is a predetermined distance after the start position of the first mark.

Abstract: A system for producing a paper product. The system includes a paper machine, an analysis tool, and a converting line. The paper machine forms a paper web having a plurality of sections, inspects the paper web to identify web properties, and marks the paper web with a plurality of marks. The analysis tool assigns action scores to each section of the paper web based upon the identified properties that section of the paper web. The converting line reads at least one of the plurality of marks on the paper web, obtains the action score associated with a second one of the plurality of marks, calculates a distance between the at least one mark read by the reading unit and the second one of the plurality of marks, and changes at least one operational parameter of the converting line when the calculated distance is less than a threshold.

Abstract: Described herein are methods and systems for reducing the tail on a parent roll. The system may comprise a web tail extending from a parent roll supported by an unwind stand. The system may further comprise one or more nozzles positioned below the web tail and configured to facilitate the rewinding of the web tail about the parent roll. The web tail may be rewound about the parent roll in a direction opposite to that which the web was initially wound about the parent roll. As a result, the length of the web tail extending from the parent roll may be reduced and is less likely to lengthen as the parent roll is ejected from the unwind stand.
