A creasing unit (10) is disclosed for creasing a pre-cut blank (28) for a hinge lid pack cigarette box. The creasing unit comprises a four-sided turret (12) carrying first, second, third and fourth crease-forming dies (18A, 18B, 18C, 18D). Lifting plates (20) are provided on each side of the turret for feeding blanks onto the crease-forming dies. A suction inlet (32) holds the blank in position on each crease forming die. A press (22) carries a complemental crease-forming die (24) for sandwiching the blank between the respective dies so as to sequentially form creased blanks (28A, 28B, 28C, 28D). The invention extends to a method of forming a crease in a precut blank. <IMAGE> |
