METHODS AND APPARATUSES FOR CONTROLLING A MANUFACTURING LINE USED TO CONVERT A PAPER WEB INTO PAPER PRODUCTS BY READING MARKS ON THE PAPER WEB

摘要

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.
