Abstract

DC60 (25/03/42) Crumpled paper products rolled into coils, such as kitchen paper towels, can be prepared to achieve a high volume and tightness by immediately steaming the dry, crumpled paper sheets before embossing them between matching steel embossing rollers. Steaming provides initial preparation to the paper sheets so that the embossing maintains their shape and structural rigidity, thus transferring greater volume and tightness to the rolled product. Furthermore, the paper sheets experience less reduction in lateral stiffness resulting from embossing. Crumpled paper products rolled into coils, such as kitchen paper towels, can be prepared to achieve a high volume and tightness by immediately steaming the dry, crumpled paper sheets before embossing them between matching steel embossing rollers. Steaming is... The initial preparation of the paper sheets ensures that the embossing process preserves their shape and structural strength, thus transferring greater material volume and density to the wound product roll. Furthermore, the paper sheets experience less reduction in toughness in the transverse direction resulting from the embossing process.

Claims (18)

1. A roll of crumpled paper with a material content of 13 cubic centimeters per gram (cc/g) or more, a roll tightness of 10 millimeters (mm) or less, and a cross-machine toughness (CD) of approximately 2000 grams per 3 inches of width (g) or more. 2. Paper rolls as per claim 1, with a material content of 15 cc/g or more. 3. Paper rolls as per claim 1, with a material content of 16 cc/g or more. 4. Paper rolls as per claim 1, with a material content of approximately 14 to approximately 20 cc/g. 5. Paper rolls as per claim 1, with a material content of approximately 15 to approximately 17 cc/g. 6. A paper roll pursuant to claim 1 with a tight, compact roll diameter of approximately 9 mm or less. 7. A paper roll pursuant to claim 1 with a tight, compact roll diameter of approximately 6 to approximately 10 mm. 8. A tightly rolled paper roll, as per claim 1, with a thickness of approximately 7 to approximately 9 mm. 9. A roll of sticky paper, as per claim 1, on a CD, approximately 2500 or more. 10. A roll of paper as per claim 1, with a adhesiveness of approximately 2200 to approximately 3500 grams, in a CD. 11. A paper roll according to claim 1 with a viscosity of approximately 2300 to approximately 3200 grams in Cd. 12. Method for making high-material paper sheets, which involves spraying steam onto dry paper sheets that are immediately wrinkled after embossing. The steamed paper sheets are placed between matching steel embossing rollers, and the steamed/embossed paper sheets are then rolled into a paper roll. 13. The method under claim 12 where the tightness of the paper roll is increased by approximately 15 percent or more relative to the same paper roll wrapped with embossed paper sheets that have not yet been steam-treated. 14. The method under claim 12, whereby the tightness of the paper roll is increased from approximately 20 to approximately 50 percent relative to the same paper roll wrapped with embossed paper sheets that have not been steam-treated. 15. The method under claim 12, whereby the tightness of the paper roll is increased from approximately 20 to approximately 35 percent relative to the paper roll wrapped with embossed paper sheets that have not been steam-treated. 16. The method under claim 12 where the stickiness in a rolled paper CD is increased by approximately 10 percent or more relative to the same roll rolled with embossed paper that has not been steam-treated. 17. The method under claim 12, where the stickiness in a CD of rolled paper is increased from approximately 10 to approximately 30 percent relative to the same roll of paper rolled with embossed paper that has not been steam-treated. 18. The method under claim 12, whereby the viscosity of a rolled paper CD is increased from approximately 10 to approximately 20 percent relative to the same roll rolled with embossed paper that has not been steam-treated (Clause 18, illustration - picture).
