摘要： The present invention relates to an easily removable paper tube used for winding material, such as fabric, a band, a film, and so forth, and a method for successively using articles, each of which uses the paper tube, and, more specifically, to an easily removable paper tube and a method for successively using articles that use the paper tube, in which the paper tube is effectively removed, without deforming a roll of material wound around the paper tube, such use of the material enabled by releasing it from the inside of the roll with the paper tube removed, thereby increasing the unrolling speed of the material, and a first article and a second article, each of which includes wound material, are connected to each other for use, thereby allowing successive provision of the articles, and thus remarkably increasing a rate of successive production.
