Abstract:
A stack of sheets comprising a plurality of individually W-folded wet sheets which are stacked in alignment one on top of each other via an overlapping portion having a predetermined width so that an underlying sheet is lifted along with an overlying sheet when the overlying sheet is withdrawn,wherein each sheet is folded about fold lines all parallel to one side of a wet sheet to define two central portions having identical widths, a top flap portion folded upward upon one central portion, and a bottom flap portion folded downward under the other central portion, the W-folded wet sheets are stacked up so that odd-numbered wet sheets and even-numbered wet sheets are alternately arranged to orient a first fold line of each odd-numbered wet sheet in an opposite direction of a first fold line of each even-numbered wet sheet, and that the top flap portion of the underlying wet sheet overlies the bottom flap portion of the overlying wet sheet to define the overlapping portion, and a dimension of each W-folded wet sheet is defined to satisfy L2+L3âˆ’Lw=L1, if an unfolded length L0 of each sheet is expressed by L0=2Ã—L1+L2+L3, wherein Lw indicates the width of the overlapping portion, L1 indicates the width of the two central portions, L2 indicates the width of the top flap portion, and L3 indicates the width of the bottom flap portion.
