Abstract:
1. A method for the production of a web of tissue paper, the method comprising the steps of: depositing a layer of aqueous suspension of papermaking fibers on at least one formation fabric; reducing the water content of said layer until the weight percentage of fibers in said layer is brought up to a first value; removing said layer from said formation fabric after reducing said water content of said layer to provide a layer free of support; wet-embossing said layer free of support in a nip between a pair of embossing rollers to form an embossed layer, said embossing rollers having protuberances and cavities, said protrusions of one of said rollers penetrating into cavities of another one of said rollers; and drying said embossed layer downstream of said nip to form a web of tissue paper.
