ABSTRACT:
A roll-like article has a core and a sheet roll wound around the core so that both side portions of the core projects from both side faces of the sheet roll. A leading end of a wrapping sheet material is fixed to the outer surface of the sheet roll and a leading end of a side face sealing material is fixed to the outer surface of each side portion of the core in a position angularly deviated in one direction from the position in which the leading end of the wrapping sheet material is fixed to the outer surface of the sheet roll. The article is rotated around the core in said one direction by a predetermined angle so that the wrapping sheet material is wound around the sheet roll and the side face sealing material is wound around the core. Each of the side edge portions of the wrapping sheet material projecting from the side faces of the sheet roll is folded along the side face of the sheet roll and the outer portion thereof is pressed against the core. Then the article is rotated around the core in said one direction by another predetermined angle so that the wrapping sheet material is further wound around the sheet roll and the side face sealing material is wound around the outer portion of each of said side edge portions which has been pressed against the core. The last two steps are repeated.
