METHODS, APPARATUS AND SYSTEMS FOR ESTABLISHING A REGISTERED SCORE, SLIT OR SLOT IN A CORRUGATED BOARD, AND ARTICLES PRODUCED THERE FROM

摘要

Methods, apparatus, and systems increase converting accuracy and consistency of corrugated articles of manufacture such as blanks, intermediates or converted structures to minimize unintended gap variations, fishtail variations and visual discord as well as to minimize unintentional loss of strength due to conversion of such articles. The constitution of converted articles formed from a corrugated board blanks according to the invention comprises at least one intelligently located score, slit or slot (hereinafter collectively “registered modification”) based upon knowledge of the corrugated board's fluted medium, including the absolute relative location of at least one fluted medium feature and/or the fluted medium geometry, such as its pitch.

主权项

1. A method for creating a registered modification in a corrugate board having at least one fluted medium that defines a flute axis and has a flute pitch, the method comprising:
ascertaining the location of a feature of the fluted medium in the corrugated board; determining a distance from the feature in a direction orthogonal to the flute axis for establishing a desired location of the registered modification; and creating the registered modification.
