ABSTRACT:
Apparatus for folding a paper sheet includes a pair of spaced parallel flaps pivotally mounted on a frame. A die has an inner side and is mounted on the frame between the flaps to allow insertion of the paper sheet to a loaded position on the inside of the die and in front of the flaps. An actuator is coupled to the flaps for alternately closing them against the inner side of the die to doubly fold the paper sheet.
