- means for feeding a printed sheet to a folding location;
- means for forming a first fold in the sheet at said folding location;
- means for forming a second fold in the sheet at a second folding location;
- recirculating loop means for recirculating the twice folded sheet toward said folding location;
- wait station means for arresting the movement of said twice folded sheet before the sheet reaches said folding location;
- means for applying glue to the edges of an address carrying sheet, said address carrying sheet being fed from glue applying means into said first folding location where a single fold is placed therein;
