Abstract
The edge portion (18) of sheet material moves about a turning plate (65), moving through first and second right angle turns (44) and (45). A turning belt (50) moves in unison with the edge portion (18) through the first two turns, and then moves through third and fourth right angle turns to advance along its return flight. An open ended slot (73) is formed between the first and second right angle turns to allow the turning belt and edge portion to move from beneath the turning plate to above the turning plate, so as to permit the edge portion of the sheet material to always turn in a downward direction as it is being turned over and placed in a folded position. Folding plate (77) guides the sheet material to help form the fold (20) in the sheet material, and separator plate (76) separates the edge portion (18) of the sheet material from the turning belt (50).
