Abstract:
Described herein are methods and systems for minimizing folding defects when rolling a paper product. The method comprises rotating a roll in a manner that draws a paper product toward the roll. The location of a pick-up point between the roll and the paper product is altered by influencing the air pressure experienced by the paper product. This may be accomplished by flowing air in one of several manners described in the specification.
