Abstract: Provided is a method for manufacturing a ribbon piece that allows suppressing a damage of a rotary die cutter. A method for manufacturing a ribbon piece of the present disclosure includes punching out a ribbon piece from a ribbon material using a rotary die cutter. The rotary die cutter includes a die roll and an anvil roll. The die roll includes a die roll body, and a cutting blade is formed to protrude on an outer peripheral surface of the die roll body. The anvil roll includes an anvil roll body, a groove is provided on an outer peripheral surface of the anvil roll body, and the cutting blade is engageable with the groove with a space.

Abstract: This roll cutter device is provided with roll units in which a thin plate material is passed between a pair of rolls. Three sets of the roll units are provided in an axial direction of the rolls in such a way that central axes of the rolls lie on one straight line in the axial direction. The configuration is such that a plurality of the roll units including an upper roll and a receiving roll exist in the axial direction.
