Abstract: In a composite sheet manufacturing device, a second roller having a plurality of first projections and a third roller are disposed so as to be adjacent to a first roller having multiple recessed areas. The outer diameters of the first and third rollers are the same size. The third roller is joined to the first roller with a first gear pair therebetween, so as to rotate at the same rotation frequency as that of the first roller. A first sheet that is fed in between the first roller and the second roller is shaped by being pushed into the recessed areas of the first roller by the first projections of the second roller. A second sheet is then superimposed onto the first sheet and is passed through the space between the first roller and the third roller, and the first and second sheets are thereby bonded to each other.

Abstract: Provided are a composite stretchable member and wearing article capable of improving design properties at the time of contraction. A composite stretchable member stretchable in a specific direction includes two sheets facing each other, and a plurality of elastic members extending along the specific direction and being stretchable in the specific direction between the sheets. The sheets are bonded to each other at first bonding sections. Each first bonding section continuously extends along the intersecting direction intersecting the specific direction and intersects the elastic members. Each elastic member is bonded to each sheet at an intersection with the corresponding one of the first bonding sections. Each first bonding section has a wavy-line-shape extending in the intersecting direction with convex portions and concave portions that alternately appear continuously.

Abstract: A sheet is used for a disposable wearable article. The sheet is such that a plurality of projections are formed on a single nonwoven fabric. A hole is formed in the apex of the projection. The projection includes a holding portion, in a periphery of the hole and at a position adjacent to the hole, for holding the projection and holding an open state of the hole.
