Abstract
A continuous, filled envelope assembly includes continuous, envelope forming webs and laterally abbreviated insert webs. The insert webs are capable of accurate feeding with the envelope webs, and also adapted to be processed independently, and include a row of spaced feed holes of one web superimposed on a non-marginal row of spaced feed holes of an adjacent web.
