Abstract

A printed sheet handling system and method for use with lazy-portrait narrow-end to narrow-end (LPEE) formatted pages web printed pages to produce document sets includes: a printer to print LPEE formatted paired document pages on a continuous web; a slitter that divides the LPEE formatted printed web into two streams of sheets; collecting each stream in separate rolls of continuous sheets; withdrawing the stream of continuous sheets from a top of one roll, rotating the second roll 180°, and withdrawing the stream of continuous sheets from a bottom of the second roll; transferring each of the unwound streams of continuous sheets to a cutter that cuts each stream into individual pages; and collating the individual pages into correctly aligned and page number-sequenced document sets.
