ABSTRACT:
Envelopes and letter sheets are mounted on a continuous carrier in such a manner that they alternate and are continuously shingled. The envelope flaps are first affixed to the carrier sheet, with the envelopes in an open position and with their flap folds adjacent and parallel to infolds between carrier sheet panels. The letter sheets are then affixed to the same panels, with the free end of each sheet extending across both an outfold and the next infold. When the carrier sheet is fanfolded, each envelope closes over the top margin of the following letter sheet, and the lower margin of each letter sheet extends across the upper margin of the following envelope.
