1. 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; andwherein at each point at which each of said at least one fold axis crosses each perforation line, the fold axis coincides with a perforation. 2. The web according to claim 1, wherein said at least one fold axis lies in the longitudinal direction of the web. 3. The web according to claim 2, wherein said at least one fold axis is located the same distance from each longitudinal edge. 4. The web according to claim 1, wherein each perforation line comprises alternating perforation tags and perforations such that adjacent sheets are connected solely by said perforation tags. 5. The web according to claim 4, wherein the extension of the perforations in the direction of the perforation line is greater than the extension of the perforation tags in the direction of the perforation line. 6. The web according to claim 5, wherein the extension of the perforations in the direction of the perforation line is at least twice the extension of the perforation tags in the direction of the perforation line. 7. The web according to claim 4, wherein each perforation tag has an extension in the direction of the perforation line which is less than 5 mm. 8. The web according to claim 1, wherein each perforation line extends substantially in a transverse direction, being perpendicular to the longitudinal direction in the plane of the web. 9. The web according to claim 1, wherein the web is a tissue web. 10. The web according to claim 1, wherein the web is a nonwoven web. 11. The web according to claim 1, wherein the web is a wet-wipe. 12. The web according to claim 11, wherein the wet-wipe is impregnated with an emulsion. 13. A dispenser comprising the web according to claim 1, said dispenser further comprising a dispensing opening through which said web is dispensed. 14. The dispenser according to claim 13, wherein the dispensing opening has a form selected from the group consisting of: circular, square, rectangular or slit-shaped. 15. The dispenser according to claim 13, comprising a dispensing insert in which the dispensing opening is located, said insert being formed of an elastic material. 16. The dispenser according to claim 13, wherein the dispensing opening has an area of between 0.8 mm2-20=2. 17. The dispenser according to claim 13, further comprising a cap adapted to cover the dispensing opening when the dispenser is not in use. 18. 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; andd. rolling the folded, perforated web into a roll about the first or second end. 19. 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. folding the web about at least one fold axis, each of which lies in the longitudinal direction of the web;c. providing the folded web with longitudinally-spaced perforation lines which extend between said fold axis and first and second longitudinal edges and which comprise at least one perforation, such that, at each point at which the at least one fold axis crosses each perforation line, the fold axis coincides with a perforation; andd. rolling the folded, perforated web into a roll about the first or second end.
