ABSTRACT:
A paper folding device includes a drive roller, a delivery roller and a follower roller extending longitudinally between and mounted rotatably on a pair of partition plates. The delivery roller is mounted slidably on the partition plates so as to permit lateral movement of the delivery roller toward and away from the drive roller. A paper support member extends longitudinally between the partition plates, and is disposed below the delivery roller and the drive roller. The paper support member confines a paper inlet to permit extension of a paper sheet to be folded therein. Rotation of the drive roller forces the paper sheet that extends into the paper support member to bend toward the drive roller and the follower roller so as to be grasped by the latter in order to form a fold in the paper sheet.
