Title: METHOD AND DEVICE FOR MANUFACTURING SHEET-SHAPED MEMBER FOR ABSORBENT ARTICLE
Abstract:
Provided is a method for manufacturing a sheet-shaped member for an absorbent article by overlapping and fixing first and second sheets (3a, 5a) at a merging position (Pj). A first pitch is set in a continuing direction on the first sheet (3a). Before reaching the state of a sheet roll (5ar), marking elements (IL) are formed on the second sheet (5a) with a second pitch smaller than the first pitch. A sensor (31s) outputs a value according to a force applied to a central roll (31m) from the second sheet (5a) wound around three rolls (31u, 31m, 31d) at fixed positions on the upstream side of a device (51), and a device (21) unwinds the second sheet (5a) from the sheet roll (5ar) on the basis of the value. The device (51) conveys the second sheet (5a) to the merging position (Pj) while changing a stretched state of the second sheet (5a) such that the marking elements (IL) are arranged with the first pitch and the marking elements (IL) are positioned at target positions on the first sheet (5a) on the basis of the first pitch.
