Abstract: The present invention relates to an apparatus for packaging various relatively thin and long rolls, which is suitable for packaging rolls having a center hole or recess in the opposite ends thereof. According to the present invention, it is possible to package the rolls with high efficiency and without the necessity of changing packaging paper rolls even when the length of the rolls to be packaged is varied. Firstly, a packaging paper is derived and cut from a packaging paper roll to a desired length and the cut paper sheet is put on a flat table. A roll to be packaged by this paper sheet is made to roll on the paper sheet in a direction normal to the paper sheet supply direction. When one edge of the packaging paper sheet is adhered to the roll to be packaged and the roll is advanced with the rotation thereof, the paper sheet wraps around the outer periphery of the roll tightly.
