An automatic sheet metal folding machine comprises two gripping members and upper and lower folding members disposed respectively above and below the gripping members. The folding members are pivotally mounted about pivot axes generally fixed during folding operations. The gripping members are adapted to clamp the sheet of metal therebetween and bring the sheet of metal to an upper or lower horizontal reference plane for folding,or some position therebetween . The upper folding member folds sheet metal downwardly and the lower folding member folds sheet metal upwardly, thereby avoiding having to turn over the sheet of metal.An orientation table may be associated with the actual folding machine for turning around a sheet of metal between successive folding operations and/or feeding and discharging the sheet of metal into and out of the folding machine.
