ABSTRACT:
A plastic sheet with a bending rule line, having satisfactory bending properties and pliability, feeling soft, having a fine appearance, and allowing a bending operation to be mechanically performed; and a ruled line blade for such plastic sheet. A bending ruled line (2) added to the bending portion of a plastic sheet (1) is formed, and shallow grooves (3) are formed along the bottom surface (2b) of the bending ruled line 2 and at predetermined longitudinal intervals, while a plurality of grooves (4) deeper than the shallow grooves (3) are formed longitudinally along the bottom surface (2b) between shallow grooves (3,3). And a ruled line blade (6) for the plastic sheet having the bending ruled line (2) added thereto is formed, and blades (7) having a small cutting depth are formed along the top surface (6b) of the ruled line blade (6) at predetermined longitudinal intervals, while a plurality of blades (8) having a larger cutting depth than in the shallow blades (7) are formed longitudinally along the top surface (6b) between the shallow-blades (7,7).
