PROBLEM TO BE SOLVED: To provide a die cut roll of a rotary die cutter in which, when holes like suction holes are opened in an outer circumferential surface of a die roll body, the strength of the die roll body is not impaired even if intervals among the holes are small, and which can easily cope with changes of positions of the opened parts of the holes without causing a cost increase.SOLUTION: Blade dies 5 are formed on the outer circumferential surface of a die roll body 1 so as to be protruded from the outer circumferential surface and extended to the outer circumferential surface, the die roll body 1 having a columnar outline and rotated around an axis O, and openings 8 communicating with holes 6 formed in the die roll body 1 are formed at positions avoiding the blade dies 5 on the outer circumferential surface of the die toll body. Lids 9 formed with through-holes 9a are detachably attached to the openings 8. |
