Abstract
Abstract A method 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: 6
Claim 1
Independent Claim
130 words
A method for forming a tufted, flared brush construction wherein each tuft is disposed at an angle different from each adjacent tuft comprising: providing a thermoplastic sheet substrate, supporting said sheet at the edges thereof, and heating said sheet until it softens; providing a plurality of synthetic filament tufts, supporting said tufts in a mutually spaced parallel relationship, and heating a common end of each of said tufts, simultaneously, until each of said ends fuses; simultaneously fusing said ends of each of said tufts to a surface of said heat softened substrate to mount said tufts thereon in the parallel mutually spaced relationship; then deforming said heat softened sheet while supported only by the edges into a convex configuration to form said flared construction with said tufts extending outwardly therefrom.
Claim 2
Independent Claim
130 words
A method for forming a tufted, flared brush construction wherein each tuft is disposed at an angle different from each adjacent tuft comprising: providing a thermoplastic sheet substrate, supporting said sheet at the edges thereof, and heating said sheet until it softens; providing a plurality of synthetic filament tufts, supporting said tufts in a mutually spaced parallel relationship, and heating a common end of each of said tufts, simultaneously, until each of said ends fuses; simultaneously fusing said ends of each of said tufts to a surface of said heat softened substrate to mount said tufts thereon in the parallel mutually spaced relationship; then deforming said heat softened sheet while supported only by the edges into a convex configuration to form said flared construction with said tufts extending outwardly therefrom.
Claim 3
Dependent Claim
116 words
The method of claim 1 wherein the step of supporting said sheet at the edges thereof further comprises providing a mold having upstanding walls defining an opening, the periphery of the opening defining a pre-determined shape, said substrate being supported by said mold at said opening; providing a die member having a convex surface, the periphery of said convex surface having the configuration of the opening in said die member; supporting said sheet at the edges thereof and heating said sheet until it softens; inserting said die member against the surface of said sheet to deform said sheet to conform to the configuration of said die member and extend through said opening in a convex configuration.
Claim 4
Dependent Claim
54 words
The method of claim 1 wherein the step deforming said heat softened sheet comprises providing a die having a convex surface, inserting said die into the surface of said heat softened sheet substrate opposite the surface mounting said tufts to deform said substrate into a configuration corresponding to the convex surface of said die.
Claim 5
Dependent Claim
52 words
The method of claim 3 wherein said die is at a temperature of less than about 75° F. when said die is inserted against the heat softened surface of said substrate, said method further comprising holding said die against said heat softened substrate until said substrate cools to form said tufted construction.
Claim 6
Dependent Claim
20 words
The process of claim 4 further comprising providing a brush handle, and mounting said tufted construction on said brush handle.
