Abstract

A method of making a wet roll includes providing a body of a roll of wet wound sheet material, where the body of the roll is connected to a tail of the roll, applying an adhesion promoter between the body and the tail, and contacting the body and the tail. The body and tail of the roll contain a wetting solution.

Claims

1. A method of making a wet roll, comprising:

providing a body of a roll of wet wound sheet material, the body connected to a tail of the roll, and the body and tail comprising a first wetting solution;

applying an adhesion promoter between the body and the tail; and

contacting the body and the tail.

2. The method of claim 1, wherein the adhesion promoter comprises a second wetting solution.

3. The method of claim 2, wherein the second wetting solution has a composition that is the same as a composition of the first wetting solution.

4. The method of claim 2, wherein the second wetting solution has a composition that is different from a composition of the first wetting solution.

5. The method of claim 2, wherein the second wetting solution is in liquid form.

6. The method of claim 2, wherein the second wetting solution is in the form of a foam.

7. The method of claim 6, wherein the second wetting solution comprises water and a surfactant.

8. The method of claim 6, wherein the second wetting solution has a composition that is the same as a composition of the first wetting solution.

9. The method of claim 1, wherein the adhesion promoter comprises an adhesive.

10. The method of claim 9, wherein the adhesive is water-soluble.

11. The method of claim 9, wherein the adhesive comprises an emulsion.

12. The method of claim 1, wherein the adhesion promoter comprises a viscous aqueous composition having a viscosity of at least about 100 centipoise.

13. The method of claim 12, wherein the viscous aqueous composition comprises a surfactant or an adhesive.

14. The method of claim 1, wherein the applying an adhesion promoter comprises applying the adhesion promoter to the body.

15. The method of claim 1, wherein the applying an adhesion promoter comprises applying the adhesion promoter to the tail.

16. The method of claim 1, wherein the applying an adhesion promoter comprises applying the adhesion promoter to the roll.

17. The method of claim 1, wherein the contacting the body and the tail comprises allowing the body to rotate onto the tail.

18. The method of claim 1, wherein the contacting the body and the tail comprises pressing the tail to the body.

19. The method of claim 1, wherein the roll of wet wound roll sheet material comprises a first wetting solution add-on greater than about 25%.

20. The method of claim 1, wherein the sheet material comprises a water-dispersible binder.

21. A method of making a wet roll, comprising:

applying an aqueous foam to a roll of wet wound sheet material, the roll comprising a body and a tail pendant to the body; and

contacting the tail to the body.

22. The method of claim 21, wherein the foam has a foamability between about 1 cm and about 4 cm.

23. The method of claim 21, wherein the foam has a foamability between about 1.5 cm and about 3 cm.

24. The method of claim 21, wherein the foam has a foamability of about 2 cm.

25. The method of claim 21, wherein the applying comprises depositing the roll into the foam.

26. The method of claim 21, wherein the applying comprises dispensing the foam onto the tail.

27. The method of claim 21, wherein the applying comprises dispensing the foam onto an exterior of the roll.

28. The method of claim 21, wherein the applying comprises providing the foam on a surface, and allowing the roll to pass through the foam on the surface.

29. The method of claim 21, wherein the contacting comprises allowing the body to rotate onto the tail.

30. The method of claim 21, wherein the contacting comprises pressing the tail to the body.

31. The method of claim 30, wherein the pressing comprises rotating the roll between an upper conveyor belt and a lower conveyor belt.

32. An apparatus for making wet rolls, comprising:

means for applying an adhesion promoter to a roll of wet wound sheet material, the roll comprising a body and a tail pendant to the body; and

means for contacting the tail to the body.

33. The apparatus of claim 32, wherein the means for applying an adhesion promoter comprises means for dispensing a wetting solution onto the wet roll.

34. The apparatus of claim 32, wherein the means for applying an adhesion promoter comprises means for forming an aqueous foam.

35. The apparatus of claim 34, wherein the means for applying an adhesion promoter further comprises means for depositing the roll onto the foam, wherein the foam is on a surface.

36. The apparatus of claim 32, wherein the means for contacting the tail to the body comprises means for rotating the body onto the tail.

37. The apparatus of claim 32, wherein the means for contacting the tail to the body comprises means for pressing the tail to the body.

38. An apparatus for making wet rolls, comprising:

a surface positioned to accept a roll of wet wound sheet material, the roll comprising a body and a tail pendant to the body; and

a solution applicator configured to contact the roll with a wetting solution once the roll is on the surface.

39. The apparatus of claim 38, wherein the surface comprises an inclined plane such that the body can rotate onto the tail along the plane.

40. The apparatus of claim 38, wherein the solution applicator comprises a spray nozzle, and the wetting solution is in the form of a foam.

41. The apparatus of claim 40, wherein the foam is dispensed from the solution applicator onto a portion of the surface, and the surface is positioned such that the roll contacts the foam on said portion of the surface.

42. The apparatus of claim 38, wherein the solution applicator comprises a drool bar.

43. The apparatus of claim 38, wherein the solution applicator comprises a spray boom.

44. A method of making a plurality of wet rolls, comprising:

providing a roll of wet wound sheet material, the roll comprising a body, and a tail connected to the body;

applying an adhesion promoter to the roll when the roll is at an application site to produce a treated roll;

transporting the treated roll away from the application site; and

repeating the providing, applying and transporting.

45. The method of claim 44, wherein the less than 10% of the treated rolls comprise a tail that is not adhered to the body.
