Claim Text:
1. A method of wrapping a folio ream, the method comprising: pre-creasing a wrap sheet such that the wrap sheet creases or dents before a front edge of the folio ream reaches the wrap sheet; positioning the wrap sheet such that an upper flap and a lower flap of the wrap sheet are ready to be folded along a rear edge of the folio ream; driving the folio ream into the wrap sheet toward a fold position; forming a bubble of wrap in the wrap sheet while the folio ream advances toward the fold position; cutting the wrap sheet while the folio ream is advancing toward the fold position, such that the lower flap extends beyond a lower rear edge of the folio ream after the ream stops at the fold position; holding the upper flap to a top portion of the folio ream; forming an upper flap fold on the rear edge of the folio ream; applying glue to an inner surface of the lower flap of the wrap sheet while holding an outer surface of the lower flap of the wrap sheet flat via a vacuum; folding the lower flap of the wrap sheet in an upward direction and simultaneously applying a force to the outer surface of the lower flap via the vacuum to keep lower flap flat during folding; affixing the inner surface of the lower flap of the wrap sheet to an outer surface of the upper flap of the wrap sheet; and reversing the folio ream to compress the glue from the lower flap to the upper flap to form a rear edge seam on the folio ream.
