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.
