In-feed and accordion folding components

Paper gates (“flippers”), and other items have been removed for clarity.

The accordion folder comprises a pair of in-feed rolls, and a folding drum that works together with two fold rolls. A document entering the folder passes through the bridge and into the in-feed rolls, which push the document into contact with the folding drum. Sensors located at the fold rolls detect the leading edge of the document and this information is used to control the folding drum in the first phase of the folding program.

The incoming document is pushed forward by the in- feed document and is captured by the lower fold roll.
