Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
59 words
A three dimensional structurally stable product comprising a plurality of structurally unstable textile fiber layers pleated together with the layers of each pleat in close contact and with contiguous multi-layer pleats in close contact, the ends of the pleats forming the sides of the product and the folds between pleats forming the upper and lower surfaces of the product.
Claim 2
Dependent Claim
59 words
A three dimensional structurally stable product comprising a plurality of structurally unstable textile fiber layers pleated together with the layers of each pleat in close contact and with contiguous multi-layer pleats in close contact, the ends of the pleats forming the sides of the product and the folds between pleats forming the upper and lower surfaces of the product.
Claim 3
Dependent Claim
13 words
The product according to claim 1, in which the layers have different porosities.
Claim 4
Dependent Claim
17 words
The product according to claim 2, in which the layers are formed of fibers of different deniers.
Claim 5
Dependent Claim
15 words
The product according to claim 1, in which the layers have different degrees of resilience.
Claim 6
Dependent Claim
15 words
The product according to claim 3 in which the layers have different total void spaces.
Claim 7
Dependent Claim
19 words
The product according to claim 4 in which the layers are formed of fibers having different cross sectional shapes.
Claim 8
Dependent Claim
15 words
The product according to claim 1, in which the layers have different degrees of rigidity.
Claim 9
Dependent Claim
17 words
The product according to claim 7, in which the layers are formed of fibers of different stiffness.
Claim 10
Dependent Claim
15 words
The product according to claim 1, in which the layers have different liquid retention characteristics.
Claim 11
Dependent Claim
15 words
The product according to claim 9, in which the layers have different total void spaces.
Claim 12
Dependent Claim
19 words
The product according to claim 9, in which the layers are formed of fibers having different cross sectional shapes.
Claim 13
Dependent Claim
15 words
The product according to claim 1, in which the layers have different gas retention characteristics.
Claim 14
Dependent Claim
24 words
The product according to claim 1, in which at least one layer contains binder fibers whereby stability is imparted to that layer when heated.
Claim 15
Dependent Claim
30 words
The product according to claim 1, in which at least one layer is impregnated with a substance which when moistened with water causes the layer to become rigid when dried.
Claim 16
Dependent Claim
38 words
The product according to claim 1, in which one layer contains binder fibers and an adjacent layer is a sheet which becomes adhesive when heated whereby pleating and heating causes the sheet to adhere to the adjacent layers.
Claim 17
Dependent Claim
33 words
The product according to claim 1, in which a flat sheet of material which melts under heat is positioned on one of the opposite surfaces and is united to the surface by heating.
Claim 18
Dependent Claim
28 words
The product according to claim 1, having in addition an unwoven sheet of material which melts under heat positioned between two adjacent layers for connecting them upon heating.
Claim 19
Dependent Claim
26 words
The product according to claim 1, having a layer of unwoven material positioned on one of the outer surfaces of the product and adhered to it.
Claim 20
Dependent Claim
61 words
The product according to claim 1, having in addition a flat sheet of heat activated adhesive material on an outer surface of the product, and a flat sheet of porous unwoven material on the upper surface of the sheet of heat activated adhesive material, whereby upon heating and cooling the sheet of porous unwoven material will be adhered to the product.
