Claim 5

The on-line recirculating folder apparatus of claim 3, including deflector means within the paper path of said recirculating loop means for either deflecting or not deflecting twice folded sheets.

Claim 6

The on-line recirculating folder apparatus of claim 4, including slitter means within the paper path of said recirculating loop means for trimming the twice folded sheets to a predetermined size.

Claim 7

The on-line recirculating folder apparatus of claim 1, including sitter means within the paper path of said recirculating loop means for trimming said twice folded sheets to a predetermined size.

Claim 8

An on-line recirculating folder apparatus for a direct mail application comprising: 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; slitter means for trimming the twice folded sheet to a predetermined size; 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; control means for actuating said wait station means for releasing the printed sheet held thereby in synchronization with the address carrying sheet reaching said first folding location such that the printed sheet is inserted inside the address carrying sheet before the address carrying sheet is double folded to form an envelope; and stacker means for receiving the folded and glued envelope.

Claim 9

An on-line recirculating folder apparatus for a direct mail application comprising: 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; slitter means for trimming the twice folded sheet to a predetermined size; 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; control means for actuating said wait station means for releasing the printed sheet held thereby in synchronization with the address carrying sheet reaching said first folding location such that the printed sheet is inserted inside the address carrying sheet before the address carrying sheet is double folded to form an envelope; and stacker means for receiving the folded and glued envelope.

Claim 10

An on-line recirculating folder apparatus for a direct mail application comprising: means for forming first and second folds in a sheet at a first and second fold location, respectively; and recirculating path means for recirculating the sheet away form said second fold location to said first fold location.

Claim 11

An on-line recirculating folder apparatus for a direct mail application comprising: means for forming first and second folds in a sheet at a first and second fold location, respectively; and recirculating path means for recirculating the sheet away form said second fold location to said first fold location.

Claim 12

The on-line recirculating folder apparatus of claim 8, including slitter means within the paper path of said recirculating path means for trimming said twice folded sheets to a predetermined size.

Claim 13

The on-line recirculating folder apparatus of claim 8, including wait station means for arresting the movement of said twice folded sheets before the sheet reaches said first 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; means for actuating said wait station means and releasing the printed sheet held thereby in synchronization with the address carrying sheet reaching said first folding location such that the printed sheet is inserted inside the address carrying sheet before the address carrying sheet is double folded to form an envelope; and stacker means for receiving the folded and glued envelope.

Claim 14

The on-line recirculating folder apparatus of claim 10, including perforator means for perforating at least one edge of the envelope in order to enhance opening of the envelope.

Claim 15

The on-line recirculating folder apparatus of claim 10, including means for inserting other sheet material into the twice folded sheet before the twice folded sheet reaches said wait station means.

Claim 16
