ABSTRACT:
A sheet folding apparatus including a plurality of sheet processing units each having a couple of folding rollers, a deflector and a folding position controlling passage. One set of the apparatus is sufficient to effect two-folding, z-folding and reversed z-folding of the sheet. A guiding member is disposed closely adjacent to the nip of the folding roller couple for conveying the sheet out of the folding positions controlling passage and for forming a new fold. When the sheet is three-folded, an undesirable double fold is prevented, which may otherwise be produced by an undesirable fold formed adjacent to the already formed fold when the sheet is folded second time.
