A packaging apparatus packages a cylindrical article having a hollow region therein by gathering an end of a wide packaging sheet wrapped around the cylindrical article, and pressing the gathered end into the hollow region in the cylindrical article. The gathered end of the packaging sheet is pressed into the hollow region in the cylindrical article by a presser which has an outside diameter smaller than the diameter of the hollow region and an inside diameter greater than the outside diameter of a core tube used to gather the end of the packaging sheet. The core tube is withdrawn from the hollow region before the gathered end of the packaging sheet is fully pressed into the hollow region by the presser. The packaging apparatus can reliably gather and squeeze a packaging sheet having long opposite ends. Since the gathered end is pressed into the hollow region in the cylindrical article, the hollow region can be sealed against entry of humidity, air, and light without use of special members such as labels or plastic caps.
