Abstract
Disclosed is an interleaved L-fold towel arrangement which minimizes a number of different types of commonly occurring paper towel dispensing failures. Each towel in the interleaved stack of towels in the present invention is comprises of a sheet which has been folded in half to substantially create a two-ply arrangement. A second fold is imparted to the towel substantially to the first fold thereby creating a lead flap and a trailing flap. The lead flap begins with the first fold and thereby creates a tab end which is two-ply and which will not delaminate on dispensing. The user will thus always be grasping a two-ply product as it is being dispensed thereby minimizing tear-out and tab-out failure. The lead flap preferably has less width than the trailing flap, thus limiting the amount of deformation which must be imparted by the trailing flap to the lead flap next to be dispensed to cause said lead flap to be drawn through the dispensing opening of a dispenser.
