Abstract

A web, such as a tissue or nonwoven web. Perforation lines in the web define sheets. The web is folded before being rolled or stacked, such that the intersection of the perforation lines and the folding line provides reliable dispensing. The web in roll or stack form, a method for forming the web, and a dispenser adapted for dispensing the web are also described.
