Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
74 words
In a tufted modular construction having a base and a plurality of mutually spaced filament tufts extending therefrom the improvement comprising: a plurality of the tuft-receiving apertures in said base, each aperture receiving a prefused homogeneous mass of said filamentary material with integral filament tufts extending therefrom so that when the mass of material cools, the said mass conforms to the geometrical confines of the aperture to hold the said tuft in the base.
Claim 2
Dependent Claim
74 words
In a tufted modular construction having a base and a plurality of mutually spaced filament tufts extending therefrom the improvement comprising: a plurality of the tuft-receiving apertures in said base, each aperture receiving a prefused homogeneous mass of said filamentary material with integral filament tufts extending therefrom so that when the mass of material cools, the said mass conforms to the geometrical confines of the aperture to hold the said tuft in the base.
Claim 3
Dependent Claim
20 words
A tufted modular construction according to claim 1 wherein both the tufts and base are formed from the same material.
Claim 4
Dependent Claim
17 words
A tufted brush construction according to claim 2 wHerein both the base and the tufts are polypropylene.
Claim 5
Dependent Claim
76 words
A tufted modular brush construction comprising: a plurality of mutually spaced filament tufts extending integrally from a brush back, said back comprising a base having mutually spaced apertures therein; each tuft comprising a plurality of synthetic filaments extending from a prefused homogeneous mass of said filamentary material, each of said prefused masses received in an aperture in said base and conforming to the geometric confines of said aperture to hold said tufts to said brush back.
Claim 6
Dependent Claim
76 words
A tufted modular brush construction comprising: a plurality of mutually spaced filament tufts extending integrally from a brush back, said back comprising a base having mutually spaced apertures therein; each tuft comprising a plurality of synthetic filaments extending from a prefused homogeneous mass of said filamentary material, each of said prefused masses received in an aperture in said base and conforming to the geometric confines of said aperture to hold said tufts to said brush back.
Claim 7
Dependent Claim
23 words
The tufted modular brush construction of claim 4 wherein the synthetic filament tufts and integral base support are formed from the same material.
Claim 8
Dependent Claim
20 words
The tufted modular brush construction of claim 5 wherein both the tufts and the integral base are formed of polypropylene.
