An elastic member in a stretched state is inserted into the two-layer part, and the inserted elastic member is bonded to the nonwoven fabric only in the crotch area, and is not bonded to the remaining front and back areas,
A pair of left and right upright elastic sheets are cut at both side latitude lines of the wide part of the top sheet and the front edge line and rear tightening line of the narrow part and folded inward at the side edge line of the narrow part to have pleats and a double-layer elastic part. The material is integrally formed with the topsheet material, and the circumferential portion of the pleats of the upright elastic material and the two-layer elastic portion facing the topsheet in the front and back regions are adhered to the upper surface of the topsheet material to form the upright elastic material. The elastic sheet member and the top sheet material are cut along the transverse cutting line to a predetermined size along with the back sheet material to form a top sheet and an upright elastic sheet, and a nonwoven fabric for the top sheet is used, and the upright elastic sheet is used for areas other than the crotch area. This makes it possible to reduce the width of the sheet and to manufacture upright elastic sheets in a continuous operation.

の接着工程を容易にするものである。A second invention of the present application is based on the first invention, wherein the nonwoven fabric for forming the top sheet is made wider than the width of the product, and the edge of the extending portion is folded in half to form a two-layer part. The inserted elastic member is bonded to the nonwoven fabric only in the crotch area, and the remaining front and back areas are not bonded, and the elastic member is bonded to the nonwoven fabric in the inseam area, and the remaining front and back areas are not bonded. A pair of left and right upright elastic sheet materials having pleats and a two-layer elastic portion are integrally formed with the top sheet material by cutting along the leading edge line and the trailing edge line and folding inward at the side edge line of the narrow portion. , position the pleats of the upright elastic sheet material in the longitudinal direction and the two-layer elastic section upward, and fold it back in a bifold shape to make the pleats two layers, so that the entire bottom surface of the upright elastic sheet material is placed in the appropriate position on the top surface of the top sheet material. The upright elastic sheet material and the top sheet material are then cut along the predetermined cutting lines along with the back sheet material to form the top sheet and the upright elastic sheet, facilitating the process of adhering the upright elastic sheet to the top sheet material. It is something to do.
