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.
