A creasing and folding machine comprises a creasing mechanism (1) for forming creases on a sheet (S) ; a folding mechanism (2) for folding the sheet (S) along the creases, the sheet (S) being conveyed from the creasing mechanism (1) ; and a controller (3) for controlling operations of the creasing mechanism (1) and the folding mechanism (2). Acreasingsection (45) comprises first and second creasing units (4,5) aligned in a conveying direction (F) of the sheet (S). The first creasing unit (4) comprises a first convex block (40) opposite to a first surface (S1) of the sheet (S); and a first concave block (41) opposite to a second surface (S2) of the sheet (S), the first convex and concave blocks (40, 41) being moved toward each other to form a first crease (400) which provides a recess on the first surface (S1) of the sheet (S) and a protrusion on the second surface (S2) of the sheet (S). The second creasing unit (5) comprises a second concave block (51) opposite to the first surface (S1) of the sheet (S) ; and a second convex block (50) opposite to the second surface (S2) of the sheet (S), the second recess and convex blocks (51, 50) being moved toward each other to form a second crease (500) which provides a protrusion on the first surface (S1) of the sheet (S) and a recess on the second surface (S2) of the sheet (S). |
