Title:
METHOD AND APPARATUS FOR FORMING A ROLLED PAPER PRODUCT
Document Type and Number:
WIPO Patent Application WO2002040260
Kind Code:
A3
Abstract:
A nested rolled paper product is shown in which raised and depressed areas are 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. Grooves 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 similar paper products. The final rolled product achieves a minimum roll diameter for a fixed roll length.
