Abstract

Toilet paper rolls are provided with angled sidewalls that impart a wavy shape to the paper as it is unwound from the roll. When individual sheets within the roll are folded or otherwise superimposed on each other, the resulting combination provides an effective width that is greater than the actual width of the individual sheets. As a result, toilet paper sheets can be made narrower than conventional toilet paper sheets while maintaining wiping performance.
