Patent ID: 8460496

Claim:
A method for producing corrugated material comprising the steps of: forming a single-faced web of corrugated material having a first edge and a spaced apart second edge; conveying the single-faced web along a track; providing an air stream to convey a portion of the single-faced web off the track and towards a double backer; engaging the portion with the double backer, whereby the double backer pulls the single-faced web therein and begins producing a corrugated material therewith; applying a cut through the first edge of the single-faced web to form a cut portion of the single-faced web; preventing the cut from extending through the second edge; stopping conveying the single-faced web along the track; and continuing to pull the generally immobile single-faced web into the double backer whereby the single-faced web separates completely from the first edge to the second edge and generally proximate the cut portion.
