Tissue containing relatively high basis weight buckled regions
First Claim
Patent Images
1. A method of making a tissue or towel sheet comprising:
- (a) forming a wet tissue web by depositing an aqueous suspension of papermaking fibers onto a forming fabric;
(b) transferring the wet tissue web to a molding fabric which imparts a three-dimensional contour to the web, said contour having spaced-apart elongated elevated regions aligned in the machine direction;
(c) removing the wet molded web from the molding fabric; and
(d) flattening the molded web, wherein elongated machine direction-oriented buckled regions are created, said buckled regions having a basis weight that is higher than the average basis weight of the web.

Abstract
Tissue and towel sheets having a pattern of spaced-apart elongated regions of relatively high basis weight oriented in the machine direction of the sheets are produced by forming a molded three-dimensional wet web having spaced-apart ridges and valleys substantially oriented in the machine direction and thereafter flattening the molded web such that the web is buckled upon itself. Upon drying, the resulting tissue sheet has a relatively flat surface texture, yet contains a high degree of cross-machine direction stretch.
