Abstract
An on-the-fly cut sheet folder has a pinch feeding conveyor for pinch feeding a medial panel of a cut sheet in order to feed the sheet in a downstream direction. A fold up plough extends along one side of the pinch feeding conveyor and a fold down plough extends along the other side of the conveyor. A folded sheet conveyor extends below and downstream of the pinch feeding conveyor. The ploughs extend beyond the downstream end of the pinch feeding conveyor and toward the folded sheet conveyor in order to guide sheets folded by the ploughs onto the downstream conveyor.
