Abstract
Abstract A repeating arrangement of embossments for roll material includes a first array of projections generally regularly spaced from one another and a second array of projections superimposed on the first array of projections with each projection of the second array extending longitudinally between two projections of the first array so as to minimize nesting of adjacent layers of material.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
142 words
A roll of material having a repeating arrangement of embossments, said arrangement of embossments comprising: means for minimizing nesting of adjacent layers of said material, said means comprising: a first array of projections generally regularly spaced from one another and arranged in a sinusoidal manner, said first array of projections being provided in all of the plies of the material and being symmetrically arranged on both sides of the material; and a second array of projections superimposed on said first array of projections with each projectionof said second array extending longitudinally between two projections of said first array and encompassing said two projections of said first array, the projections of said second array being provided in all of the plies of the material and having a height which is substantially the same as the height of the projections of the first array.
Claim 2
Dependent Claim
