METHOD AND APPARATUS FOR FORMING A ROLLED PAPER PRODUCT

摘要

A nested rolled paper product is shown in which raised and depressed areas a re formed in a sheet. The depressed areas may comprise square shapes, rounded shapes or other geometric shapes that are capable of aligning or nesting in registration when the sheet is rolled to form a reduced diameter rolled product. A high loft through air drying fabric is employed to imprint a high caliper pattern into the sheet in such a way as to nest raised portions, resulting in a more compact product having a minimized roll diameter. Groove s or channels in the sheet are capable of aligning as the sheet is rolled. The resulting rolled product may be toilet tissue, paper towels, or other simila r paper products. The final rolled product achieves a minimum roll diameter fo r a fixed roll length.
