Abstract

A cutter apparatus for cutting a workpiece of an absorbent article that is being transported in a transport direction, includes: a cutter roller having a cutter blade projecting from an outer circumferential surface thereof; and an anvil roller that receives the cutter blade at an outer circumferential surface thereof disposed to face the outer circumferential surface of the cutter roller. While rotating mutually in the transport direction, the cutter roller and the anvil roller cut the workpiece by allowing the workpiece to pass between the rollers. In at least one of the cutter roller and the anvil roller, a dynamic-balance correction section is provided which corrects the dynamic balance of the roller so that the sum of the values of balance quality (mm/sec) defined in JIS B 0905 at one end and the other end of the roller in a rotational-axis direction is 6 or less.
