Abstract: The present invention is directed generally to a folder apparatus for sheets, and more particularly a folder with a fold path transverse to a feed path. In an embodiment, the folder comprises a channel for receiving a sheet, feed rollers for feeding the sheet along the feed path and through the channel, the feed rollers are axially aligned with the feed path, guide rollers positioned transverse to the feed path for feeding the sheet along a fold path to pinch rollers which pinch the sheet to form folds. The paper path does not reverse and the folding action is smooth so that noise and vibration are reduced. Also, the folder has a smaller footprint than other folders.
