The envelope staging section includes structure for holding and forwarding an envelope fed from an envelope feeder. Envelope transport structure transports an envelope forwarded from the envelope staging section to the insertion section. The envelope transport structure includes a vacuum deck located at the insertion section and a vacuum drum located between the envelope staging section and the vacuum deck. The envelope transport structure further includes a plurality of envelope transport belts operating in cooperation with the vacuum drum and the vacuum deck. A plurality of backstops are located at the downstream end of the insertion section. A pivoting sucker bar assembly lifts open a top panel of the envelope when the envelope is against the backstops. A pair of rotating funnel guide horns guide enclosures being conveyed for insertion into the envelope. A dual belted enclosure transport assembly located upstream of the insertion section transports a collation toward the insertion section. A plurality of overhead pushers seize the enclosures from the enclosure transport, stuff the enclosures into the opened envelope and push the stuffed envelope from the insertion section into engagement by output belts that are located downstream from the insertion section and above the envelope transport belts.
