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.
Claims19
A web having a primary extension in a longitudinal direction and being defined by first and second longitudinal edges and first and second ends, said web comprising a plurality of sheets arranged in an end-to-end fashion in the longitudinal direction;
- each sheet being defined by a portion of the first and second longitudinal edges of the web and by perforation lines which extend between said first and second longitudinal edges;
- said perforation lines comprising at least one perforation;
- wherein the web is folded along at least one fold axis, each of which lies in the longitudinal direction of the web and crosses said perforation lines;
- said web being in the form of a roll, which has been rolled about the first or second end;
- and
- wherein at each point at which each of said at least one fold axis crosses each perforation line, the fold axis coincides with a perforation.
A method for forming a web comprising the steps of:
- a. providing a web having a primary extension in a longitudinal direction and being defined by first and second longitudinal edges and first and second ends;
- b. providing the web with longitudinally-spaced perforation lines which extend between said first and second longitudinal edges and comprise at least one perforation;
- c. folding the perforated web about at least one fold axis, each of which lies in the longitudinal direction of the web;
- such that, at each point at which the at least one fold axis crosses each perforation line, the fold axis coincides with a perforation;
- and
- d. rolling the folded, perforated web into a roll about the first or second end.
