Abstract

Provided is a slitter device including a cutter device (20) having a plurality of disk-shaped rotary blades (23) provided according to the number of divisions of a sheet material (SM), and having a support roll (21) to which the rotary blade (23) is pressed and around which the sheet material (SM) is wound, wherein a roll driving motor (MR) that is provided to rotationally drive the support roll (21) is controlled such that a tension of the sheet material is maintained to a desired degree and cutting of the sheet material by the cutting device is performed appropriately. The slitter device (1) includes a first tension detecting unit for obtaining a raw-cloth tension value which is a tension value of a sheet material fed out from a let-off mechanism (10); a second tension detecting unit for obtaining a divided material tension value which is the sum of the tension values of each of divided sheet materials; and a drive controller (47c) which controls an operating state of the roll driving motor such that the raw-cloth tension value and the divided material tension value coincide or substantially coincide with each other based on the comparison result of the raw-cloth tension value and the divided material tension value.
