A creasing-folding machine comprises, in sequenced arrangement, a sheet-feeding unit (12), sheet-feeding driven rollers (20, 22), a first creasing unit (30) and a second creasing unit (130) similar to the first unit but turned upside down with respect to it, and a transfer belt (42) for feeding the sheet to a subsequent folding station. Each creasing unit comprises a vertically movable, transverse shaping bar (32), connected to driving means, and an abutment bar (38), opposite to the first bar (32) and grooved complementarily to it. |
