ABSTRACT:
An envelope forming apparatus has a vacuum table with apertures through which a vacuum is applied onto the surface of the vacuum table. A series of parallel endless belts move across the vacuum table and transport an envelope blank across the vacuum table. The vacuum through the apertures in the vacuum table holds the blank on the belts as they move across the vacuum table and as the blank is folded by a plowshare folder located relative to the vacuum table. Alternatively, a single wide belt with apertures may be substituted for the series of parallel belts.
