Abstract
A paper sheet folding apparatus includes three rotatably mounted folding rollers which cooperate in pairs to provide two folds in a single paper sheet or a packet of paper sheets. A first paper support member on one side of the rollers cooperates with a delivery roller to flex paper into one of the pairs of rollers to provide a first fold in the paper. A second paper support member on the opposite side of the rollers receives the folded paper and cooperates with the first pair of rollers to flex the paper into the second pair of rollers to provide a second fold in the paper. The second pair of rollers then discharges the paper from the apparatus.
