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 method of producing a paper product. A paper web is formed on a paper machine. The paper web has a plurality of sections. The web is analyzed to perform at least one of inspecting and identifying properties. The web is marked with a plurality of marks. At least one mark is marked at each of the plurality of sections. Thereafter, the web is wound with a winder to form a parent roll. A paper rating is assigned to each section based upon properties in that section that are identified. The web is unwound from the parent roll on a converting line having a plurality of operational parameters. At least one of the plurality of marks is read with a mark reading unit. The paper rating associated with the at least one mark is obtained. At least one operational parameter of the converting line is changed based upon the rating.

1. A method of producing a paper product, the method comprising:
(a) forming a paper web on a paper machine, the paper web including a plurality of sections; (b) analyzing the paper web with a web analysis unit to perform at least one of inspecting the paper web and identifying properties in the paper web; (c) marking the paper web with a plurality of marks, at least one mark being marked at each of the plurality of sections; (d) winding the paper web with the winder to form a parent roll after the paper web has been inspected and marked; (e) assigning a paper rating to each section of the paper web based upon the properties in that section of the paper web that are identified in the analyzing step; (f) unwinding a paper web from a parent roll on a converting line having a plurality of operational parameters; (g) reading at least one of the plurality of marks with a mark reading unit; (h) obtaining the paper rating associated with the at least one mark read by the reading unit; (i) changing at least one operational parameter of the converting line based upon the paper rating; and (j) converting the paper web into a paper product.
