PROBLEM TO BE SOLVED: To provide a perforated line working method for forming a perforated line in a conveyance direction on carried sheets or a continuum of materials to be worked, which alleviates shock to a machine blade to reduce waste and wear even in selectively forming the perforated line on the material to be worked. SOLUTION: While not working, the machine blade 16 is brought into contact with the surface of the material 19 to be worked and rotated in response to conveyance of the material 19. While working, the machine blade 16 is pressed by a pressing means from a non-working state onto a receiving barrel 17 in the thickness direction of the material 19 and rotated in response to the conveyance of the material 19, thereby forming the perforated line 19A.
