Zusammenfassung:	A roll-like article (2) has a core (4) and a sheet roll (6) wound around the core (4) so that each end portion of the core (4) projects beyond a side face of the sheet roll (6). A leading end of a wrapping sheet material (12) is fixed to the outer surface of the sheet roll (6) and a leading end of a side face sealing material (14) is fixed to the outer surface of each side portion of the core (4) at an angularly displaced position. The article (2) is rotated around the core (4) through a predetermined angle so that the wrapping sheet material (12) is wound around the sheet roll (6) and the side face sealing material (14) is wound around the core (4). Each of the side edge portions of the wrapping sheet material (12) projecting from the side face of the sheet roll (6) is folded along the side face of the sheet roll (6) and the outer portion thereof is pressed against the core (4). Then the article (2) is again rotated so that the wrapping sheet material (12) is further wound around the sheet roll (6) and the side face sealing material (14) is wound around the outer portion of each of said side edge portions which has been pressed against the core (4). The last two steps are repeated.
