ABSTRACT:
By reducing the overlap distance O of the interfolded sheets in the upper layer of a stack of interfolded sheets, sheet tears and/or multiple dispensing can be avoided for the initial sheets dispensed. By increasing the overlap distance O of the interfolded sheets in the lower layer of a stack of interfolded sheets, fallback of the subsequent sheets can be avoided. To maximize the number of sheets that can be placed into the same sized dispenser, the folded width of all sheets in the stack should be substantially the same. The interfolded stack is especially useful in an upright dispenser to improve sheet dispensing, but can also be utilized in a flat dispenser.
