A method for creating mailpieces from a single web of printed material. The web of printed material includes a continuous web having a width and a length, the length comprised of a series of attached sheets. The series of attached sheets is comprised of envelope sheets and content pages. The content pages are rectangular in shape and may be oriented relative to the envelope sheets in a number of different configurations. In some configurations, two sets of content pages and/or envelope sheets can be printed across the width of the web. The method starts with cutting consecutive attached sheets into separated sheets. The content pages belonging to a same mailpiece are accumulated together. The separated envelope sheet is transported, bypassing the accumulating and turning steps. The accumulated and turned content pages are then merged with the envelope sheet, and the envelope sheet is folded and closed around the accumulated content pages to form a finished enclosing envelope.
