Abstract: A method for producing laminated embossed webs useful as toweling, napkins, placemats and the like. The method employs a novel arrangement of embossing and laminator rolls to achieve a nested configuration of the embossed, inwardly-extending projections, and avoids the speed limitations inherent in prior machines.

Abstract: A tissue product with at least four plies made of tissue paper base sheet or nonwoven comprises:



a first outer ply and a second outer ply and at least two inner plies between the first outer ply and the second outer ply, wherein
only one of the inner plies is un-embossed;
the outer plies comprise a micro-embossing pattern;
at least one of the outer plies comprises a décor embossing pattern; and
at least two adjacent inner plies comprise the un-embossed inner ply and one micro-embossed inner ply; wherein the density of the micro-embossed protrusions of the micro-embossed inner ply is different to the density of further embossed protrusions of the micro-embossing pattern of the outer ply which is adjacent to the micro-embossed inner ply.

Abstract: A means of making a multi ply structural panel by eliminating the top liner in the corrugating process. The present invention is made possible through modification to the corrugating rolls of the singlefacer. The design modification to the rolls involves incorporation of slots that run around the circumference of one roll and mating creasing tools incorporated around the circumference of the other of the corrugated roll set. These slots and creasing tools are incorporated across the existing flutes of the corrugating rolls.
