Abstract
A method and apparatus are disclosed for forming printed paper products having a folded or pocket portion, for example inserts for magazines and brochures having a reply envelope. A moving web of paper from which the inserts are made is first folded along the edges thereof to form the folded or envelope portion of the insert. Thereafter, printing is carried out on the folded web. Since folding precedes printing, a web having a width which exceeds the maximum width that the printing press can accommodate may be used. In this way, an insert having a width up to the maximum width that the printing press can accommodate and/or inserts having envelope portions and/or envelope flap portions of increased size are obtained.
