METHOD AND DEVICE FOR MANUFACTURING SHEET MEMBER FOR ABSORBENT ARTICLE

Document Type and Number:

WIPO Patent Application WO/2017/216927

Kind Code:

A1

Abstract:

The present invention has: a supply step for conveying a continuous sheet (3a) in a conveyance direction that is the continuity direction of the sheet (3a) and thereby sending the sheet (3a) into a fabrication processing part (L3aK); a fabrication step in which a fabrication device (34) of the fabrication processing part (L3aK) performs fabrication intermittently in the conveyance direction on absorbent-article 1 portions of the sheet (3a) at a fabrication processing position (P3a) in the conveyance direction; a position adjustment step performed at an adjustment processing position (P35) in the conveyance direction, the position adjustment step comprising adjusting, in a CD direction intersecting with the conveyance direction, the position of an end part (3ae) of the sheet (3a) in the CD direction; and a detection step for detecting a trace of the fabrication remaining on the sheet (3a) at a detection processing position (P36) downstream from the fabrication processing position (P3a) and the adjustment processing position (P35) and outputting the detection result. In the supply step the tension value in the conveyance direction of the continuous sheet (3a) during sending into the fabrication processing part (L3ak) is adjusted on the basis of the detection result.
