Abstract:
1. An apparatus for producing a deep-nested embossed product comprising: a first embossing member having a first surface and a plurality of first embossing elements extending from the first surface, the plurality of first embossing elements being discrete embossing elements and being disposed in a first non-random pattern; a second embossing member having a second surface and a plurality of second embossing elements extending from the second surface, the plurality of second embossing elements including at least one linear embossing element and being disposed in a second non-random pattern wherein the second non-random pattern is coordinated with the first non-random pattern; and, the first embossing member and the second embossing member being aligned such that the respective coordinated first non-random pattern and second non-random pattern nest together such that they engage each other to a depth of greater than about 0.01 mm; wherein the second embossing member includes a plurality of linear embossing elements in a second pattern and wherein the first embossing elements and the second embossing elements, when engaged with each other, provide an engagement embossing pattern wherein at least one of the linear embossing elements is separated from every other linear embossing elements by at least one first embossing element; wherein the at least one linear embossing element includes an at least partially enclosed region and the first embossing pattern includes at least one first embossing element that, when engaged with the second embossing pattern, is disposed within the at least partially enclosed region of the linear embossing element; wherein the first embossing elements comprise a distal end and a sidewall, at least a portion of the distal end and at least a portion of the sidewall meeting at a transition region, wherein the transition region has a radius of curvature of greater than about 0.075 mm; wherein the distal end of at least one of the first embossing elements is generally curved; wherein every linear embossing element is separated from every other linear embossing element by at least one first embossing element; and wherein the second embossing pattern includes a plurality of linear embossing elements including at least partially enclosed regions and the first embossing pattern includes a plurality of first embossing elements that, when engaged with the second embossing pattern, at least some of the plurality of first embossing elements are disposed within the at least partially enclosed regions of the linear embossing element.
