Abstract
A slitter device 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, 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 control device which includes a comparator to which the first tension detecting unit and the second tension detecting unit are connected, and which compares the raw-cloth tension value and the divided material tension value with each other; and a drive controller which controls an operating state of a 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 comparator.
