Document Type and Number:
WIPO Patent Application WO/2017/038231
Kind Code:

Abstract:
The present invention provides a method for producing a composite sheet (20) for an absorbent article (1), the composite sheet (20) having a first continuous sheet (21), a second continuous sheet (22) and rubber-based fibers (23) disposed between the first continuous sheet (21) and the second continuous sheet (22). This method is characterized by: rotating a first rotating body (25) provided with first projections (251) and second projections (252) projecting radially outwardly, and conveying the first continuous sheet (21), the second continuous sheet (22) and the rubber-based fibers (23) in a state where the rubber-based fibers (23) disposed between the first continuous sheet (21) and the second continuous sheet (22) are at least partially interposed between the first projections (251) and the second projections (252); and processing the first continuous sheet (21) and the second continuous sheet (22) by sandwiching the first continuous sheet (21) and the second continuous sheet (22) between the first projections (251), the second projections (252) and a second rotating body (26) during conveyance by the rotating body (25).
