The present invention provides a cutter device that cuts a workpiece of an absorbent article that is conveyed in a conveyance direction. The cutter device comprises a cutter roll whereon a cutter blade is disposed that protrudes from the external circumference face, and an anvil roll that receives the cutter blade by an external circumference face that is positioned in opposition to the external circumference face of the cutter roll. The cutter roll and the anvil roll rotate against one another along the conveyance direction, and cut the workpiece by passing the workpiece between the cutter roll and the anvil roll. At least one of either the cutter roll or the anvil roll further comprises a motion balance correction unit that corrects the motion balance of the roll such that the sum of the values of balance quality (mm/sec), as defined by JIS B 0905, of one end side and the other end side of the roll in the rotational axis direction is less than or equal to six. |
