A cutting device provided with a guide between press rolls has been proposed to prevent warp deformation of a cotton swab or the like (Japanese Patent Laid-Open No. 63-46155). However, when such a device is used as an absorbent body for a sanitary napkin, a warp preventing press roll suitable for the length (15 cm to 30 cm) of the sanitary napkin becomes a huge one having an excessive radius of curvature.
