Appl. No.:

12/574325

Assignee:

KIMBERLY-CLARK WORLDWIDE, INC. - Neenah WI

International Classification:

A47K 10/16
B65H 18/28
B65H 18/10

B65H 19/28

US Classification:

2421601, 2425323, 2425322

Abstract:

Coreless tissue rolls can be produced without having to use an adhesive to form a hollow center. Instead, moisture can be used to promote light hydrogen bonding between the layers of the tissue web that line the hollow center. The hydrogen bonding provides sufficient structure to maintain the shape of the hollow center without rendering the tissue web surrounding the passageway unusable. Passageways can also be formed in accordance with the present disclosure that are substantially circular so that the rolls will easily spin on a spindle. In an alternative embodiment, moisture is not used in constructing the wound tissue roll.
