Title:
吸収性物品に係るシート状部材の製造方法、及び製造装置
Document Type and Number:
Japanese Patent JP6676664
Kind Code:
B2
Abstract:
The present invention is provided with: a step for conveying a composite sheet 30mf in which a plurality of elastic members 35a, 35a…, which extend along the conveyance direction in a state of being stretched in the conveyance direction, are interposed and fixed, in a state of being arranged in the CD direction, which intersects the conveyance direction, between a first non-woven fabric 30mf1 which is continuous in the conveyance direction, and a second non-woven fabric 30mf2 which is provided overlapping the first non-woven fabric 30mf1 in the thickness direction, and which is continuous in the conveyance direction; a step S50 in which push-in members 55p are pushed in the thickness direction into positions between adjacent elastic members 35a, 35a in the composite sheet 30mf in the CD direction, to form through holes h in the composite sheet 30mf; a step S60 in which a tensile force is applied to the composite sheet 30mf in the CD direction at a position located further downstream than a through-hole-formation processing position P51 where the through holes h are formed in step S50; and a step S70 in which the composite sheet 30mf is processed at a position located further downstream in the conveyance direction than a tensile force application position P60 where the tensile force is applied in step S60.
