Method for wetting and winding a substrate
View Patent ↗A method of making wet rolls includes providing a web of material, applying a wetting solution to the web to produce a wet web, and winding the wet web into a roll. The wetting solution may be applied at an add-on greater than 25%, and the web may travel at a speed of at least 60 meters per minute.
1. A method of making a wet careless roll comprising:
a) providing a wet web of material;
b) breaking the wet web and forming a cigarette from the leading edge of the break;
c) forming a roll of the wet web around the cigarette in a roll forming pocket;
d) separating the wet web roll from the web while repeating step b); and
e) discharging the separated wet web roll from the roll forming pocket.
2. The method of claim 1 , wherein the roll forming pocket comprises a first roller, a second roller, and a third roller.
3. The method of claim 1 , wherein the roll forming pocket comprises a first roller, a second roller, and a third roller; the wet web contacting the first roller, the second roller, and the third roller; the first, second and third rollers rotating in the same circular direction; and the second roller rotating in a circular direction opposite from the direction of movement of the wet web.
4. The method of claim 1 , further comprising perforating the web.
5. The method of claim 4 , further comprising making the break of step b) along a line of perforation.
6. The method of claim 1 , wherein the method is performed in an environment which is substantially free of contaminants.
7. The method of claim 1 , wherein the web travels at a speed of at least 60 meters per minute.
8. The method of claim 1 , wherein the wet web comprises an add-on of a welling solution of at least about 25%.
9. A method of making wet coreless rolls comprising:
providing a wet web;
breaking the wet web;
winding the wet web into a roll using a roll forming pocket;
the roll forming pocket comprising a first roller, a second roller and a third roller; the wet web contacting the first roller, the second roller, and the third roller; the first, second and third rollers rotating in the same direction; and the second roller rotating in a direction opposite from the direction of movement of the wet web; and
discharging the wet web roll from the roll forming pocket.
10. The method of claim 9 , wherein the wet web is made by applying a welling solution to a basesheet.
11. The method of claim 10 , wherein the wetting solution is applied at an add-on greater than about 25%.
12. The method of claim 10 , wherein the welling solution is applied at an add-on between about 25% and about 700%.
13. The method of claim 10 , wherein the welling solution is applied at an add-on between about 50% and 400%.
14. The method of claim 10 , wherein the wetting solution is applied at an add-on between about 100% and 350%.
15. The method of claim 10 , wherein the wetting solution is applied at an add-on between about 150% and 300%.
16. The method of claim 10 , wherein the wetting solution is applied at an add-on between about 200% and 250%.
17. The method of claim 10 , wherein the wetting solution comprises salt.
18. The method of claim 9 , wherein the method is performed in an environment which is substantially free of contaminants.
