To provide a method for manufacturing a disposable diaper having a flute structure and a joining device used in the method, capable of preventing the occurrence of creases in a joining part of both sheets in intermittently joining two layer sheets of a flute structure.
Pattern blocks 11, 12 are formed near both sides in the axial direction of a roll body 10 of an emboss roll 1, and while both sheets are joined by holding superposed sheets S1, S2, S3 between the pattern blocks and bonding means 2, 3, both sheets are brought into contact with the roll body in an area outside of an area including the pattern blocks to apply the turning force of the emboss roll. Thus, both sheets are joined without causing creases in the superposed parts thereof. Both sheets are abutted on the emboss roll at a predetermined angle of embrace, so that both sheets can be joined without the occurrence of creases in superposed parts.
