Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 39 words
A method for embossing a convolutely wound roll to avoid nesting comprising the steps of embossing web material with co-mating rolls having a pattern repeat in the machine direction at least equal to the circumference of the finished roll.
Claim 2
Independent Claim 39 words
A method for embossing a convolutely wound roll to avoid nesting comprising the steps of embossing web material with co-mating rolls having a pattern repeat in the machine direction at least equal to the circumference of the finished roll.
Claim 3
Dependent Claim 19 words
The method of claim 1 in which each of said co-mating rolls has an integral number of pattern repeats.
Claim 4
Dependent Claim 14 words
The method of claim 1 in which said co-mating rolls are constructed of steel.
Claim 5
Dependent Claim 12 words
The method of claim 1 in which the pattern is substantially random.
Claim 6
Dependent Claim 16 words
The method of claim 4 in which the pattern includes a number of different size embossments.
Claim 7
Dependent Claim 18 words
The method of claim 5 in which the pattern embossments is substantially similar to that of FIG. 5.
Claim 8
Dependent Claim 8 words
The finished roll produced according to claim 1.
Claim 9
Dependent Claim 15 words
The method of claim 1 in which the said web material is a paper web.
Claim 10
Dependent Claim 16 words
The method of claim 7 in which the finished roll is a roll of toilet tissue.
Claim 11
Dependent Claim 17 words
The method of claim 7 in which the said finished roll is a roll of kitchen toweling.
Claim 12
Dependent Claim 12 words
The method of claim 1 in which said co-acting rolls are rubber-steel.
Claim 13
Dependent Claim 12 words
The method of claim 1 in which said co-acting rolls are paper-steel.
Claim 14
Dependent Claim 23 words
The method of claim 1 in which each of the co-acting rolls have a circumference equal to an integer of the pattern repeat.
Claim 15
Dependent Claim 16 words
The method of claim 13 in which each of the co-acting rolls are of different diameter.
Claim 16
Dependent Claim 34 words
The method of claim 1 in which a small repeat pattern is surrounded by a randomized plurality of embossments, said plurality having a sketch repeat greater than the circumference of the finished roll product.
Claim 17
Dependent Claim 32 words
The method of claim 1 in which randomized patterns having a sketch repeat length greater than the circumference of the finished product roll are interspersed between MD strips of small repeat patterns.
Claim 18
Dependent Claim 59 words
A convolutely wound roll comprising web material wound on itself and having a pattern of embossments arranged in a repeat pattern, said repeat pattern having a length at least equal to the circumference of the finished roll and wherein the embossments of any top convolutely wound web sheet will be substantially displaced from the embossments of the underlying sheet.
Claim 19
Dependent Claim 59 words
A convolutely wound roll comprising web material wound on itself and having a pattern of embossments arranged in a repeat pattern, said repeat pattern having a length at least equal to the circumference of the finished roll and wherein the embossments of any top convolutely wound web sheet will be substantially displaced from the embossments of the underlying sheet.
