Abstract
Abstract A method and apparatus for making flared, tufted, brush constructions is disclosed. A plurality of synthetic filament tufts are picked, and the ends fused. Simultaneously, the fused ends are mounted parallel on a heat softened, thermoplastic support. Before the support cools, it is deformed to a convex configuration so that when the support cools, a flared, tufted construction is formed, suitable for mounting on a handle. The support may also be deformed to a concave configuration so that the tufts converge.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
73 words
A tufted, flared brush construction comprising: a semi-rigid thermoplastic sheet substrate having a convex configuration; a plurality of mutually spaced synthetic filament tufts, each of said tufts mounted on said substrate at an end fused integrally thereto, each of said tufts extending outwardly at an angle different from the angle of each adjacent tuft and substantially perpendicular to the surface of said substrate mounting said tuft; handle means for supporting said tufted construction.
Claim 2
Dependent Claim
73 words
A tufted, flared brush construction comprising: a semi-rigid thermoplastic sheet substrate having a convex configuration; a plurality of mutually spaced synthetic filament tufts, each of said tufts mounted on said substrate at an end fused integrally thereto, each of said tufts extending outwardly at an angle different from the angle of each adjacent tuft and substantially perpendicular to the surface of said substrate mounting said tuft; handle means for supporting said tufted construction.
Claim 3
Dependent Claim
71 words
A tufted, flared brush construction comprising a hollow, spherical, thermoplastic substrate; and a plurality of mutually spaced synthetic filament tufts mounted about the surface of said sphere, each of said tufts having an end fused integrally with said substrate, and each of said tufts extending from said substrate at an angle different from the angle of each adjacent tuft and substantially perpendicular to the surface of said substrate mounting said tuft.
Claim 4
Dependent Claim
71 words
A tufted, flared brush construction comprising a hollow, spherical, thermoplastic substrate; and a plurality of mutually spaced synthetic filament tufts mounted about the surface of said sphere, each of said tufts having an end fused integrally with said substrate, and each of said tufts extending from said substrate at an angle different from the angle of each adjacent tuft and substantially perpendicular to the surface of said substrate mounting said tuft.
Claim 5
Dependent Claim
45 words
The tufted construction of claim 2 wherein said spherical substrate comprises a pair of hemispherical, hollow thermoplastic members having a plurality of mutually spaced synthetic filament tufts extending therefrom; and means for joining the periphery of said hemispherical members to form a sphere shaped substrate.
