ABSTRACT:
A machine for folding flexible sheets, such as paper, and more particularly blueprints and the like, comprises a plurality of fold stations, each including a pair of pinch rolls and a deflector selectively operable to cause a sheet of material fed to the machine to be fed between a pair of pinch rolls and thus folded, or to be fed past the pinch rolls and not folded, an infeed tray to feed a sheet of material to the fold stations, a plurality of first sensing devices on the infeed tray spaced apart in the direction of travel of the sheet to sense the presence of a sheet of material on the infeed tray, and a sensing device at each fold station to sense the presence of a sheet being folded at that station, said sensing devices operatively connected with the deflectors to operate the deflectors to cause the sheet of material to be folded at the next succeeding fold station only when the sheet of material is sensed simultaneously by the spaced sensing devices on the infeed tray and the sensing device at the next preceding folding station.
