<p>A dust collecting paper bag for a vacuum cleaner, wherein a base paper is joined to form a cylindrical body having a top surface portion (1) and a lower surface portion (2). Then, right and left portions of the cylindrical body are folded to make the cylindrical body flat. Right and left fold gazettes (6) have their fold positions displaced in a widthwise direction from one another. Displaced positioning of gazette folds of the dust collecting paper bag for vacuum cleaners makes end flaps of the cylindrical body overlapping smooth to make joining and sealing perfect.</p> |
