Abstract
The moisture content of a base paper for manufacturing a paper tube is controlled to a predetermined value. Water-soluble adhesive is applied to a side of the base paper in such a small amount as to cause the adhesive to ridge on the side of the base paper, and the ridging adhesive is uniformly smoothed over the side of the base paper. The base paper is wound into a tube.
